Cryptolocker: Menace of 2013

Quote:
Security software company Symantec this month named Cryptolocker the “Menace of the Year”.

Bitdefender logged over 12,000 victims in a week last month. That's not huge on a global scale but it should be a big enough number to make businesses pay attention.

While relatively few have been affected so far, many of those that have succumbed experienced a world of pain, as the victim stories below will attest.

For anyone who hasn’t been paying attention, Cryptolocker is a variant of ransomware that unlike its predecessors does not work by locking a computer. Instead, it encrypts all data and demands a ransom in Bitcoins for the user to regain access.

It is usually distributed as an executable attachment disguised as a Zipped document and presented as an invoice or report or similar via a spam campaign.

All of that would be frightening enough for individual users, but Cryptolocker more than most trojans is a threat to businesses too. that's because it not only attacks data on the PC on which the executable was opened, but also on devices and drives connected to that PC.

So, what’s it like being on the receiving end?

New crypto ransomware hits US, Russia and Europe

Quote:
Researchers have discovered a new crypto ransomware threat which they claim has at least 50 variants all designed to hit up victims for a $150 payment.

The Cryptolocker malware, which hit the headlines recently for encrypting victims' files and demanding $300 to unlock them, now has a cheaper rival, which researchers at security startup IntelCrawler say began large-scale distribution on 5 December.

The newer crypto-locking malware first checks the infected machine has an internet connection by calling up adobe.com, then deletes any original files the victim has on their PC after first making encrypted copies of them and adding a ".perfect" extension to the files. The attackers place a "CONTACT.TXT" file in each directory, which provides their contact information for victim that choose to buy the decryption key.

Its easy when the files and such look so real and official. It's usually those who are aware of such scams, or the overly paranoid, that have been able to avoid the issue. Though lots of innocents have been caught as well.

Near Miss

The business my friend works for had a near miss.
The accountant at the business got hit by it.

Luckily:
  • My friend set up their network (using Linux)
  • The accountant panicked and turned off the laptop when he saw the message (apparently the first thing it does is display the ransom message)
This meant that the accountant wasn't able to connect to the network (username and password required) and spread it to the Network drives.
