New ransomware charges $300 (early bird special) to unlock your files

PandaLabs has discovered a new strain of ransomware which it is calling Trj/Crypdef.A. The new variant works like other forms of ransomware in that it locks infected computers and encrypts a user’s files before demanding a ransom to get control back.

The ransom demand says "By purchasing a license from us, we are able to rescue your files 100% guaranteed for a very low early bird price of only $300". Don’t think $300 is a bargain? Well, in five days the demand goes up to $600, and after ten days it will cost you $1,000 to unlock your system and restore your files.

Payment is by Bitcoin only and the demand helpfully tells victims to check the current price of the virtual currency using www.bitcoinaverage.com before making a payment.

As always, the best way to avoid this threat and others like it is by ensuring your operating system is up to date, and that you’re running a good antivirus program. Avoid opening email messages and files from unknown sources or visiting potentially unsafe web pages.
