Web Infection Holds Computer Files Hostage (Ransom-ware for Windows)
Associated Press | May 24, 2004 | TED BRIDIS

WASHINGTON (AP) -- Computer users already anxious about viruses and identity theft have new reason to worry: Hackers have found a way to lock up the electronic documents on your computer and then demand $200 over the Internet to get them back.

Security researchers at San Diego-based Websense Inc. uncovered the unusual extortion plot when a corporate customer they would not identify fell victim to the infection, which encrypted files that included documents, photographs and spreadsheets.

A ransom note left behind included an e-mail address, and the attacker using the address later demanded $200 for the digital keys to unlock the files.

"This is equivalent to someone coming into your home, putting your valuables in a safe and not telling you the combination," said Oliver Friedrichs, a security manager for Symantec Corp.

The FBI said the scheme, which appears isolated, was unlike other Internet extortion crimes. Leading security and antivirus firms this week were updating protective software for companies and consumers to guard against this type of attack, which experts dubbed "ransom-ware."

"This seems fully malicious," said Joe Stewart, a researcher at Chicago-based Lurqh Corp. who studied the attack software. Stewart managed to unlock the infected computer files without paying the extortion, but he worries that improved versions might be more difficult to overcome. Internet attacks commonly become more effective as they evolve over time as hackers learn to avoid the mistakes of earlier infections.

"You would have to pay the guy, or law enforcement would have to get his key to unencrypt the files," Stewart said.

The latest danger adds to the risks facing beleaguered Internet users, who must increasingly deal with categories of threats that include spyware, viruses, worms, phishing e-mail fraud and denial of service attacks.

In the recent case, computer users could be infected by viewing a vandalized Web site with vulnerable Internet browser software. The infection locked up at least 15 types of data files and left behind a note with instructions to send e-mail to a particular address to purchase unlocking keys. In an e-mail reply, the hacker demanded $200 be wired to an Internet banking account. "I send programm to your email," the hacker wrote.

There was no reply to e-mails sent to that address Monday by The Associated Press.

FBI spokesman Paul Bresson said more familiar Internet extortion schemes involve hackers demanding tens of thousands of dollars and threatening to attack commercial Web sites, interfering with sales or stealing customer data.

Experts said there were no widespread reports the new threat was spreading, and the Web site was already shut down where the infection originally spread. They also said the hacker's demand for payment might be his weakness, since bank transactions can be traced easily.

"The problem is getting away with it - you've got to send the money somewhere," Stewart said. "If it involves some sort of monetary transaction, it's far easier to trace than an e-mail account."

Why the heck aren't the police or FBI tracking down both the Email address and bank account!

I would have kept quiet and had LE pay the $200 so they could track where it goes.

The crime isn't the demand for $200, it's the denial of the data's owner to have access to it. With a business that had to far exceed the $200. That should also have made it grand theft in all likelihood.

Because we have a Criminal Justice System, not a Victim Justice System.

Has something changed? I wasn't aware that "Justice" had anything to do with our Legal System these days.

Admittedly, the average Keystone Kops law enforcement organization isn't going to care about $200 worth of extortion that they have zero idea how to deal with, but I can see the case where this cretin is going to piss off the wrong guy. It might be somebody with international banking connections who figures out how to kill this criminal. Hopefully.
