flaws writes "The guys at Secure Science Corporation have written a revealing article demonstrating the relationship with the most recent Ransom-based Trojan (known as Glamour) and some previous data stealing trojans. They include an open source decrypting utility for unlocking your files if infected, and some stats that are a bit disturbing. According to their report, in the past 8 months, 152,000 victims have been infected, and over 14.5 million records were discovered to be logged by the trojan."

What is the infection vector for these things? Is it email, P2P networks fooling people into believing that mp3 really is an EXE file?
although I cant believe that people are stupid enough to fall for a nigerian scam wanting to deposit 30 billion dollars in their accounts overnight either.

If you've used any common p2p apps like eDonkey or the like, you'll notice that when you search for something, even if you type some arbitrary crap like "huoshgahgauoiwhrgoaghnaj" you'll also get "huoshgahgauoiwhrgoaghnaj.mp3.exe" and "huoshgahgauoiwhrgoaghnaj pics xxx mpeg avi.exe" or similar shit. So someone searching for a keygen is going to get "exactly the keygen they wanted.exe"

"Well, considering that Windows by default doesn't show the file extension for known filetypes, as far as all the noobs can tell, the file they just double-clicked was "Artist - song.mp3", since they wouldn't even see the .exe at the end. Sweet deal eh?
Which is why I've been telling people for years the first thing they should do after installing Windows (immediately after selecting the "Show hidden files and folders" option and unchecking (clearing) the "Hide extensions for known file types" and "Hide protected operating system files" options in Control Panel -> Folder Options, View tab) is to run REGEDIT and do a 'Find' for all occurrences of "NeverShowExt" and delete every single one found. All of them (spare none).

Do people still really open attachments from people that do not know or were not expecting? Are people really executing unknown .exe files?
A fun experiment: Write a small, harmless program that when executed send a single ping to your home machine/ server and an equally simple program to count the incoming pings on said system.
Write a short message saying something like "The well known virus 'YouAreTooStupid' is again spreading across the Internet. Please run the attached program to clean and/ or immunize your PC", attach your little program and send it to twenty people. Then sit back and watch your counter...

No, they are going to look for a "free decoder program," ha ha ha. Oh, the joys of non free software.
Jokes aside, this trojan is aimed at corporate users. If it's easy to fix, big dumb companies will tell their sheep to bring forth their problems and fix them. If the creeps had been bright enough to use real encryption, there would be no solution and embarrassed users will try to fix the problem themselves. Of course, paying $300 to an extortionist will get you nothing more than another request for money unless they want to sell you back each file. For more evidence of this, see Vista pricing.
