Microsoft RPC exploit could be a packaged deal

Thursday, October 30th, 2008

While Microsoft has labeled Thursday’s emergency patch MS08-067 as “critical” and provided a rareout-of-cycle fix because its exploit could easily be used as worm on a compromised network, one security researcher doesn’t think it will happen that way.

“It’s likely we’re going to see this packaged with some other attack.” said Ben Greenbaum, senior research manager at Symantec. “A Web-based attack, for example. We’re looking out for are exploits of this being bundled with client-side exploits or Trojans so that the worm can get past corporate firewalls and get behind that firewall into the internal network.”

Comparisons have been made to Zotob, an RPC worm that spread like wildfire in 2005. Remote Procedure Calls (RPC) allows programmers to run code either locally or remotely; a flaw within them is ideal for creating a worm.

“The potential is certainly there,” Greenbaum said, adding that modern day attackers are “looking to create as much revenue for themselves as possible, and part of that equation means avoiding detection. What we’re likely to see is that this will be added to a wide variety of attack tool kits already available.”

“It’s possible–but it’s not likely–that we’ll end up seeing a purpose-built worm that only exploits this one vulnerability,” he said.

Since the patch came out Thursday morning, Symantec has seen increased scanning on ports 139 and 445, ports that exploits of MS08-067 would use.

There are some mitigating factors. Most firewalls, with default settings in place, should not allow an exploit of this penetrate that firewall, he said. However, home networks with File and Printer Sharing could fall victim to a bundled attack using this exploit.

The greatest danger is to systems running Windows XP and Windows 2000; Microsoft has ranked the patch as critical for these systems. On Windows Vista, Windows Server 2008, or Windows 7 pre-Beta, if the firewall is disabled, and File and Printer sharing enabled, an anonymous user could use this exploit to connect but would do so only at the lowest possible integrity setting, Greenbaum said. Microsoft has rated the patch only as important for those operating systems.

AIDS treatment should start sooner

Thursday, October 30th, 2008

People who have the AIDS virus should start drug treatments sooner than current guidelines recommend, suggests a large new study that could change the care of hundreds of thousands of Americans.

The study found that delaying treatment until a patient’s immune system is badly damaged nearly doubles the risk of dying in the next few years compared to patients whose treatment started earlier.

Doctors have thought it would be better to spare patients the side effects of
AIDS drugs
as long as possible.

“The data are rather compelling that the risk of death appears to be higher if you wait than if you treat,” said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, which helped pay for the study.

If the results prompt doctors to change practice - as Fauci and other AIDS specialists predict - several hundred thousand Americans who are not taking
AIDS drugs
now would be advised to start.

The study was reported Sunday at an
infectious diseases
conference in Washington.

About 56,300 Americans are newly infected with HIV each year. The virus ravages T-cells - “helper cells” of the immune system that fight off germs. Once that happens, people can fall prey to a host of diseases that prove fatal.

Powerful drug combinations available since the mid-1990s have transformed HIV infection into a manageable chronic condition rather than the death sentence it once was. But they can cause heart and cholesterol problems, diarrhea, nausea and other
side effects
. They also must be taken faithfully or resistance develops and the drugs stop working.

That is why guidelines by the government and the International AIDS Society recommend that patients who are not yet having AIDS symptoms delay starting on the drugs until their T-cell counts fall below 350 per cubic millimeter of blood (healthy people have more than 800).

“There was this thinking, maybe the drugs were worse than the disease. If you could wait as long as you possibly could wait, you would have fewer
side effects
,” said Dr. Robert Schooley,

infectious diseases
chief at the
University of California, San Diego.

The new study is the largest to look at whether that advice is sound. Researchers led by Dr. Mari Kitahata of the University of Washington in Seattle pooled information on 8,374 people in the United States and Canada with T-cell counts of 351 to 500 from 1996 to 2006.

About 30 percent started taking
AIDS drugs
right away; the rest waited until their T-cell counts fell below 350, as guidelines recommend.

“We found a 70 percent improvement in survival for patients who initiated therapy between 350 and 500″ compared to those who waited, Kitahata said.

Two other recent studies found that people who start taking AIDS drugs while their T-cell count is above 350 have a better chance of getting their count back to normal than those who start later. Another key study found that briefly interrupting treatment to give patients “drug holidays” puts them at grave risk.

“These studies have all shown the same thing - that we were starting too late” and need to keep treatment going once it starts, said Schooley. He helped write the AIDS society guidelines and consults for several companies that make
AIDS drugs
.

The bigger problem is that as many as a third of people diagnosed with HIV only discover they are infected after their T-cell counts already have fallen below 350 and they have serious complications.

“People are still being tested and identified way too late,” and the new study shows how important it is to test and find people sooner, said Dr. Daniel Kuritzkes, an AIDS specialist at Brigham and Women’s Hospital in Boston.

Newer drug combinations that have come out in recent years have fewer
side effects
. Also, some require only a pill or two a day, making adherence less of an issue.

These advances and the new study justify a fresh look at the guidelines, Fauci said. He predicted that doctors would not wait for them to change to start treating patients sooner.

The new study’s findings do not apply to HIV patients who also have hepatitis, kidney damage or other medical
problems
, or who are pregnant - doctors have long advised that these people start treatment as soon as they are diagnosed.

EXCLUSIVE - GM, Chrysler clear major deal issues - sources

Thursday, October 30th, 2008

General Motors Corp and Cerberus Capital Management have resolved the major issues in a proposed GM-Chrysler merger, but the final form of any deal would depend on the financing and government support available, sources familiar with the talks said on Wednesday.

Both sides have agreed that GM Chief Executive Rick Wagoner would lead the combined automaker, the sources said.

A merged GM-Chrysler would be the largest automaker by global sales, but analysts have cautioned it would struggle to turn around the overlapping Detroit-based operations of two companies that have seen mounting losses tied to a global downturn in sales.

GM shares jumped by as much as 11 percent in reaction to news of progress in the merger talks. GM bonds also moved higher and the cost to insure the company’s debt against default fell.

As GM seeks some $10 billion in U.S. government aid to support the deal, Chrysler owner Cerberus is in its own set of intense discussions with banks to refinance billions of dollars in Chrysler debt, the sources said.

GM has been in talks with Cerberus about buying Chrysler since last month, but the discussions have been snagged by difficulty in securing investment or financing.

A decision by the Bush administration to provide the government’s first funding for the auto sector since the $1.5 billion bailout of Chrysler in 1980 has been widely seen as the merger’s best chance for success.

GM and Cerberus declined comment. A United Auto Workers union spokesman had no immediate comment.

Chrysler’s lending consortium — which includes JPMorgan Chase & Co, Goldman Sachs Group Inc, Citigroup Inc and Morgan Stanley — has not made a decision yet, and talks are complicated because lenders have sold part of the debt to other investor groups, the sources said.

The banks hold the first-lien loan of $7 billion issued to finance the Cerberus buyout of an 80 percent stake in Chrysler from Daimler AG last year. Banks have been selling off parts of it in an effort to trim their exposure to risky leveraged buyout debt.

A failure to refinance that debt could require the merged company to pay it off in full because of a change in control. That would be difficult given GM and Chrysler’s struggle to preserve cash at a time when their core operations are under increasing strain.

GM burned through $1 billion a month in the second quarter and its cash burn rate is expected to have increased in the third quarter when its global sales dropped 11 percent.

Chrysler, now in a dead heat with Honda Motor Co for the No. 3 spot in the U.S. market, has been hardest hit by the slump because of its dependence on the U.S. market for some 90 percent of sales.

Chrysler’s sales have fallen 25 percent through September, while GM’s sales are down 18 percent. Industry-wide sales are expected to drop near 30 percent in October.

GM and Chrysler have responded by slashing jobs and delaying vehicles in development.

But as it sought backing for the proposed deal, GM has consulted with the UAW during its talks with Cerberus, people familiar with the negotiations said.

As a condition of government support, GM has offered to merge the auto operations in a way that protects as many jobs and as much of the Chrysler sales volume as possible, sources have said. Taken together, GM and Chrylser have some 97,000 union-represented factory workers.

GMAC ROLE SEEN KEY

One element of the GM-Cerberus talks has involved GMAC, the GM-affiliated finance company in which Cerberus owns a controlling 51 percent stake, people with knowledge of the talks have said.

Cerberus is keen to increase its holding in GMAC and has considered merging it with Chrysler Financial, Chrysler’s captive finance company, at a time when the financial firms stand to benefit from new government steps aimed at the tight credit markets, sources said.

GMAC, which has some $20 billion in outstanding debt and has faced a tougher market for its financing, said on Tuesday that it had been approved to borrow through the U.S. Federal Reserve’s recently created commercial paper facility.

A U.S. Treasury spokeswoman said on Wednesday that GMAC and other automotive finance companies could sell distressed assets in upcoming auctions to shore up their balance sheets.

GM shares were up 8.5 percent at $6.78 on the New York Stock Exchange late on Wednesday afternoon, off an earlier high at $6.98.

GM’s 8.375 percent bond due 2033 was up 3.75 cents to 32.5 cents on the dollar, according to MarketAxess. GMAC’s 8 percent bond due 2031 was up 8 cents to 50.5 cents.

The cost to insure GMAC and GM debt with credit default swaps dropped. Credit default swaps on GM’s debt have fallen to around 60 percent the sum insured upfront, from around 70 percent at the start of the week.c

Iran’s Rafsanjani blames finance ‘tsunami’ for low oil price

Saturday, October 25th, 2008

The influential former president of OPEC’s second largest oil producer Iran on Friday called the world financial crisis a tsunami which has dragged down oil prices and caused a huge loss of revenue.

“This is the first wave of the tsunami to reach us. The oil price has fallen from 147 dollars a barrel to around 64 dollars. This is a huge loss” for Iran, Akbar Hashemi Rafsanjani said in a Friday prayer sermon on state radio.

“Our economists and government and parliament officials should cooperate and be prepared. The first wave has arrived and it was dangerous for oil-producing nations,” added Rafsanjani.

He heads the Expediency Council, Iran’s top arbitration panel, and also the Assembly of Experts which supervises the work of the country’s supreme leader, Ayatollah Ali Khamenei.

“We have to be able to control future such waves or they will inflict serious harm on our society, especially the poor,” Rafsanjani said.

Oil prices hit record highs in July of above 147 dollars a barrel, but plunged to their lowest for 17 months on Friday, despite news that OPEC will cut output by 1.5 million barrels per day.

New York’s main contract, light sweet crude for December delivery, tumbled to 62.85 dollars a barrel — a price last seen in May 2007.

Ahead of Friday’s OPEC meeting in Vienna, Iran urged a cut in the cartel’s output to combat the sharp dive in oil prices as the world battles a financial crisis experts say it is the worst since last century’s Great Depression.

New MS Therapies Show Promise

Friday, October 24th, 2008

Two medications may prove to be advances in the treatment of multiple sclerosis, researchers say.

In one study, an experimental drug called oral fumarate (BG00012) substantially reduced symptoms in patients with relapsing-remitting multiple sclerosis, according to a phase II clinical trial by European and North American researchers.

And in a second trial, researchers found that the leukemia drug alemtuzumab (Campath) was about 70 percent more effective than another drug already widely used to treat MS. However, alemtuzumab also had significant side effects, including bleeding disorders, a greater risk of thyroid disease, and infections. This prompted experts to say that much more research is needed before alemtuzumab can be prescribed to treat multiple sclerosis.

Multiple sclerosis is a nervous system disease that affects the brain and spinal cord. It damages the myelin sheath, the material that surrounds and protects nerve cells. This damage slows or blocks messages between the brain and the body, according to the U.S. National Library of Medicine.

Symptoms of the disease can include visual disturbances; muscle weakness; trouble with coordination and balance; sensations such as numbness, prickling, or “pins and needles;” and thinking and memory problems.

It’s not known what causes multiple sclerosis. It may be an autoimmune disease, which happens when the body attacks itself. MS affects women more than men, and it often begins between the ages of 20 and 40. An estimated 400,000 Americans have the disease. Usually, the disease is mild, but some people lose the ability to write, speak or walk. There’s no cure for MS, but medicines may slow it down and help control symptoms, according to the National Library of Medicine.

The 24-week study of BG00012 included 257 patients, ages 18 to 55, who were randomly assigned to receive either 120 milligrams of BG00012 once a day (64 patients), 120 milligrams three times a day (64 patients), 240 milligrams three times a day (64 patients), or a placebo (65 patients). The patients were assessed at weeks 12, 16, 20 and 24.

MRI brain scans showed that patients treated with 240 milligrams of BG00012 three times a day had 69 percent fewer new gadolinium enhancing (GdE) lesions — a marker of MS-related inflammatory activity — from week 12 to 24 than those who received the placebo. They also had fewer new or enlarging T2-hyperintense and T1-hypointense lesions at week 24.

The study also found that BG00012 reduced the annual relapse rate by 32 percent, but this finding wasn’t statistically significant. Patients who received the drug were more likely than those in the placebo group to suffer adverse events such as abdominal pain and hot flush. Dose-related adverse events in patients taking the drug included headache, fatigue and feeling hot, the researchers said.

“Longer-term (phase III) studies of BG00012 in larger patient populations are underway to define its place in the future of relapsing-remitting multiple sclerosis treatment. If these studies show similar relapse rate reductions with BG00012, interferon beta, and glatiramer acetate, BG00012 could be a suitable initial treatment for relapsing-remitting multiple sclerosis,” wrote Professor Ludwig Kappos, of University Hospital Basel, in Switzerland, and colleagues.

The study was published in the Oct. 24 issue of the The Lancet.

In an accompanying comment in the journal, Professor Per Soelberg Sorensen and Dr. Finn Sellebjerg of the Danish Multiple Sclerosis Research Center, noted that “BG00012 might have a favorable benefit-to-risk ratio profile compared with its oral competitors and the currently available first-line injectable drugs. However, we will have to await the results from the ongoing large phase III trials to establish the place of BG00012 and of other oral drugs in the treatment of relapsing-remitting multiple sclerosis.”

The study of the leukemia drug alemtuzumab, which temporarily depletes white blood cells and is part of a class of drugs called monoclonal antibodies, included 334 patients. Patients were randomly assigned to get either alemtuzumab or interferon beta, a standard MS therapy, for three years.

Alemtuzumab reduced by 74 percent the risk of MS relapse, the researchers reported in the Oct. 23 issue of the New England Journal of Medicine.

“The ability of an MS drug to promote brain repair is unprecedented,” Alasdair Coles, of Cambridge University in England, and one of the study’s leaders, told the AFP news service. “We are witnessing a drug which, if given early enough, might effectively stop the advancement of the disease and also restore lost function by promoting repair of the damaged brain tissue.”

However, in an accompanying journal editorial, Dr. Stephen L. Hauser, a neurologist at the University of California, San Francisco, said the “toxic effects associated with alemtuzumab considerably dampen any enthusiasm for its routine use in patients with multiple sclerosis until more is known about its long-term safety and sustained efficacy.”

That sinking feeling again

Friday, October 24th, 2008

They are mere numbers that have zeros attached, but carry a behavioural burden within them. And so, when the BSE Sensex cut through the 10,000 mark to close at 9,772 and the NSE Nifty knifed through 3,000 to close at 2,943, a doomsday loomed large.

A fall of almost 4 per cent or 398 points on the Sensex was led by a meltdown in metal stocks and slowdown in auto. The big boys of steel — Tata Steel and Steel Authority of India - fell over 14 per cent each on expectations of lower commodity prices following lower demand from China.

On the auto front, Tata Motors crashed 15 per cent, while Apollo Tyres fell 12 per cent, following uncertainty in demand. Tata Steel and Tata Motors were also the biggest losers among Sensex stocks.

Making matters worse, Reliance Industries, the biggest market mover today, fell 7.6 per cent. The carnage in India mirrored the rest of Asia and Europe, where the stockmarket barometers of all countries fell 4-7 per cent.

Beleaguered Aussies seek Prabhakar’s help

Friday, October 24th, 2008

THE AUSTRALIANS believe that more than the Indian spinners, it was the reverse swing that Ishant Sharma and Zaheer Khan got at Mohali that cost them the second Test. Disturbed by the fact that their bowlers were unable to produce any kind of reverse swing, the Australian team management have reportedly sounded out former India pacer Manoj Prabhakar to help their bowlers prepare for the Delhi Test that starts from October 29.

Prabhakar was contacted by a member of the Australian camp on Thursday and asked if he was willing to help Brett Lee and Co. at the nets.

Prabhakar, who was Delhi’s bowling coach last season, played a big part in the development of Ishant Sharma and was undoubtedly one of the finest exponents of reverse swing in India. According to sources close to Prabhakar, he is yet to make up his mind on the offer and is a little apprehensive about helping the Australians.

“Yes, he has been contacted and asked to help the Australian bowlers, but Prabhakar hasn’t made up his mind as yet,” said the source. “He is a little apprehensive about how the administration will react if he said yes.

He has not said either yes or no,” the source added.

OPEC chief says output cut must consider consumers, producers

Thursday, October 23rd, 2008

OPEC President Chakib Khelil said on Wednesday that the cartel must weigh the impact of a prospective decision to cut oil output on both consumers and producers hit by a global financial crisis.

“The decision has to take into account the interests of the consumers but also (has to) take into account the interests of the producers,” Khelil told reporters on arrival in Vienna ahead of Friday’s special meeting of the Organization of Petroleum Exporting Countries.

OPEC’s member countries are calling for a cut to the cartel’s output of between one and 2.5 million barrels a day to help shore up oil prices. However the cartel’s kingpin Saudi Arabia has yet to reveal its preference.

Crude futures on Wednesday tumbled to 16-month lows, mainly on news that demand for crude is slumping in the United States, the world’s biggest energy consumer.

Prices slid under 65 dollars a barrel in London, down about 56 percent from a record high of 147.5 dollars reached in July.

“This is going to be a very important meeting” in Vienna on Friday, said Khelil, who is also energy minister for OPEC member Algeria.

“It comes in the middle of a financial crisis where lots of countries have been affected,” added Khelil in reference to both oil-consuming and producing nations.

He said that OPEC did not want producers, affected by the financial crisis, to be further hit by “very low” oil prices, which reduce their incomes.

Crude oil prices slumped in trading on Wednesday on news of surging US energy reserves that highlighted a fall in demand caused by a global economic slowdown.

A sharp rise in the dollar also put pressure on the dollar-priced commodity, making it more expensive for buyers using weaker currencies, traders said.

Brent North Sea crude plunged five percent, to a 16-month low of 64.59 dollars a barrel. New York’s light sweet crude slumped to 66.73 dollars — a level last seen on June 14, 2007.

Friday’s “extraordinary” meeting in the Austrian capital, home to OPEC’s headquarters, has officially been called “to discuss the global financial crisis, the world economic situation and the impacts on the oil market.”

It was originally planned for November 18 but has been brought forward, a switch analysts said was because OPEC wanted to quickly bring a halt to tumbling prices.

Khelil on Wednesday noted that crude stocks were currently “very high.”

He added: “There is an excess of supply and some of us are not able to sell the crude. I think the question of reduction has to be discussed” on Friday.

Khelil also said that non-OPEC oil producers should consider cutting output. OPEC produces 40 percent of the world’s oil and its official output quota stands at 28.8 million barrels per day. Russia is the largest non-OPEC oil producer.

Russian President Dmitry Medvedev on Wednesday told the cartel’s secretary general he wanted closer cooperation with the organization.

“For our energy institutions, cooperation with OPEC in forming energy policy is a key priority,” Medvedev told OPEC Secretary General Abdalla Salem El-Badri in Moscow.

“Russia is also a major producer and exporter of oil and is interested in supporting stable, predictable oil prices,” Medvedev said.

Earlier the OPEC secretary general said he would not be asking Russia to join in any arrangement to support prices.

“I will not ask Russia to cut production. I will request an exchange of information about the situation on the market and the financial crisis,” he said.

British Prime Minister Gordon Brown last week said it was “absolutely scandalous” that OPEC members were considering cutting production “so they can push up the price of oil” in times of economic turmoil.

El-Badri on Tuesday hit back, insisting that OPEC had no responsibility to keep production high and oil prices low to ease pain in the West caused by the credit crunch.

Competition Heats Up for Space Station Cargo Contract

Thursday, October 23rd, 2008

Three U.S. firms are preparing to submit final bids for a pair of NASA International Space Station cargo services contract worth up to $3.1 billion through 2015.

Space Exploration Technologies (SpaceX) of Hawthorne, Calif., and Orbital Sciences Corp., of Dulles, Va., have been honing their rival offers with the aid of $500 million in demonstration money NASA awarded under its Commercial Orbital Transportation Services (COTS) program.

Also in the hunt for the two contracts NASA intends to award Dec. 23 is Chicago-based PlanetSpace, a commercial space startup that has built a team around the biggest names in the aerospace business.

PlanetSpace announced Oct. 22 that it added Boeing to a team lineup that already included Lockheed Martin Space Systems of Denver and Minneapolis-based Alliant Techsystems.

The day before, the PlanetSpace met with NASA officials in Houston to present and defend their proposal for meeting NASA’s International Space Station cargo delivery needs. Final offers for the Commercial Resupply Services contract are due Nov. 7.

PlanetSpace is the only one of the three teams that submitted proposals back in June to develop their re-supply system without the aid of NASA COTS funding. However, PlanetSpace has been meeting with NASA officials periodically to review progress on its system under an unfunded COTS agreement signed in early 2007.

SpaceX is entitled to receive up to $278 million from NASA for meeting progress milestones spelled out in a 2006 COTS award. Orbital Sciences’ 2007 COTS award is worth up to $171 million. Both companies are required to show steady progress towards demonstration flights of their respective systems.

NASA has said since the inception of the COTS program that winning demonstration funding was no guarantee of landing a cargo launch services contract. NASA also made clear from the get-go that the eventual contract competition would be open to any U.S. firm.

Under the Cargo Resupply Services solicitation issued earlier this year, NASA said it was looking for each selected team to deliver a minimum of 20 metric tons to the space station over the seven-year life of the contract and bring back a minimum of three metric tons of materials over the same time period. No minimum dollar value was specified for the contract, but PlanetSpace Chairman Chirinjeev Kathuria said NASA has spelled out a maximum contract value of $3.1 billion.

Al Simpson, acting director of advanced programs, human space flight at Lockheed Martin Space Systems, said meeting NASA’s minimum order with the PlanetSpace system would entail 10 to 12 launches over the life of the contract.

Lockheed’s role on the team includes working with Boeing to develop, produce and operate modular Orbital Transfer Vehicles that would serve as cargo carriers to the International Space Station.

The cargo vehicle would launch atop the Athena 3 rocket Alliant Techsystems is building largely from heritage hardware. The first stage is a 2.5-segment version of the four-segment solid rocket boosters ATK builds for NASA’s space shuttle fleet. The second stage is the ATK Castor 120 engine used on Athena 1, Athena 2 and Orbital’s Taurus 1 rockets. PlanetSpace is the overall prime contractor and would manage the Commercial Resupply Services contract.

PlanetSpace team officials said Boeing brings its expertise as International Space Station prime contractor to an already well-rounded team.

“A very strong team member has just joined us,” Simpson said. “We have been at this for quite a while now and have, I think, a very valid offer to address NASA’s needs for cargo re-supply and give them the assurance that somebody can actually bring cargo to the station.”

Simpson said PlanetSpace could be ready to conduct cargo launches in 2011.

SpaceX and Orbital Sciences continue to forge ahead on separate cargo delivery demonstration flights planned for late 2009 and 2010, respectively.

NASA, meanwhile, issued a notice Oct. 15 that it intends to buy regular crew transportation and rescue services from Russia through June 2016 under a sole source contract currently under negotiation. The notice, issued by NASA’s Johnson Space Center, indicates the U.S. space agency is negotiating solely for Soyuz flights and related services, not for cargo deliveries aboard the unmanned Russian Progress ship.

NASA officials have pledged to leave Progress out of the new deal to demonstrate its commitment to buying re-supply services from the U.S. private sector.

Colombia radio host connects hostages with family

Thursday, October 23rd, 2008

On the day she was rescued after six years of jungle captivity in rebel hands, Ingrid Betancourt broke with protocol on the airport tarmac when she was supposed to be taking questions from reporters.

She asked for one journalist by name whose voice was familiar but whom she had never met.

“My brother, forever. Come here for my ‘freedom hug,’” Betancourt said.

As millions watched on live TV, Herbin Hoyos slid through the security cordon, past the defense minister, military chief, Betancourt’s mother and other dignitaries. The two embraced.

For 14 years, Hoyos has hosted “Kidnapped Voices,” a radio program for relatives of Colombian kidnap victims to broadcast messages to their loved ones.

Now Hoyos, a former kidnap victim himself, is being honored for work that has occupied most of the 38-year-old reporter’s adult life.

This month he won Colombia’s highest award for journalists, the Simon Bolivar prize for Journalist of the Year, followed by the National Peace Prize, sharing it with William Perez, a medic held with Betancourt who attended to her and other hostages as they battled tropical illnesses.

“The program has taught me the greatest humility lesson anyone could learn in life,” Hoyos told The Associated Press. “Every day, I experience human drama.”

Since launching the program, Hoyos says, he has received “freedom hugs” from 11,017 people freed or rescued from ransom- and politically motivated kidnappings.

But he worries that after the July 2 rescue of the highest profile hostages — Betancourt and three U.S. military contractors — those they left behind will be forgotten. Mostly soldiers and police officers, some held for as long as a decade, the hostages continue to waste away amid a paucity of efforts to secure their release.

Until recently, Colombia had the world’s highest kidnapping rate, which experts believe has now been surpassed by Mexico. Iraq is also a contender.

According to government figures, Colombia had more than 2,800 unresolved kidnappings through the end of June. The cases date back to 1996 and include people disappeared and presumed dead.

The government attributes 700 kidnappings to leftist rebels. But officials familiar with the issue, speaking on condition of anonymity because superiors will not permit them to publicly clarify the matter, say rebels probably hold no more than a few hundred.

Hoyos was a young reporter when the leftist Revolutionary Armed Forces of Colombia, the same group that held Betancourt, abducted him in March 1994.

He was rescued by the army 17 days later. But during his short time in captivity, Hoyos met another FARC hostage, Nacianceno Murcia, who “chewed me out because we journalists weren’t doing anything for the kidnapped.”

Murcia was released for ransom in 1996 but died two years later of a pancreatic ailment he’d acquired as a hostage.

As soon as Hoyos was freed, he went to his bosses at Caracol radio in Bogota and asked for air time to give kidnap victims radio messages from their loved ones.

And so began a show that Hoyos says has transmitted more than 328,000 messages to thousands of kidnap victims over its 14 years.

“I respectfully request of ’senores kidnappers’ that you let the kidnapped turn on the radio,” Hoyos says to launch his pre-dawn program every Sunday. “Here begins ‘Kidnapped Voices.’ ”

In their jungle prisons, the kidnapped hear heartwarming tidings of marriages and births, as well as heartbreaking news of a spouse’s or parent’s death.

Betancourt’s mother and children hardly ever missed a week to recount the most minute details of their daily lives.

At the end of each show, Hoyos promises the hostages a “freedom hug” when they are released.

Most family members call in their messages by telephone, though many also knock on the doors of Caracol’s studios and await Hoyos to usher them into the studio.

Hoyos says he has no social life. He works 20-hour days, is separated from his wife and doesn’t drink alcohol. To relax, he flies ultralight planes.

Miriam Torres, whose businessman son, Juan Camilo Mora, has been missing for three years, faithfully sends messages through Hoyos’ program each week — even though she has no confirmation that he was kidnapped.

“The families of rich people and politicians have the power to seek freedom for their kidnapped. We only have Herbin,” Torres said.

For years, Hoyos’ show got little attention.

Then Betancourt, a dual French national, was kidnapped in February 2002 while running for president. A year later, the three U.S. contractors fell into the FARC’s hands when their surveillance plane crashed in rebel territory.

“The subject began to take on international relevance, and people in Colombia began to become a bit more sensitive,” Hoyos said.

Every week, Hoyos repeats that his program won’t go off the air until Colombia’s last kidnap victim is freed.

On the day of her release, Betancourt told him, “Let’s put an end to that program.”

But this weekend, like every weekend, Hoyos once again will be at the mike.

“To us, he’s a part of our families,” Betancourt told the AP in an e-mail from France. “His voice accompanied us for years in the jungle. Friends for always.”
