File-NUKING Cryptolocker PC malware MENACES ‘TENS of MILLIONS’ in UK

BACKUP BACKUP BECKUP
OR END UP PAYING OUT £560 TO GET YOUR FILES BACK!!

This is quite possibly the cleverest and most lethal virus/malware to ht the UK and its going viral because people are clicking it!

Here is the low-down on what it does:

Lurking within the attachments is a Trojan called Cryptolocker that, when executed, silently installs itself and quietly begins encrypting documents one by one on the Windows PC using tough-as-nails AES256. When it’s finished, it demands a ransom payment of 2 Bitcoins (at least 500 quid or 800 bucks) to decrypt the data, which must be paid within a time limit.

The software nasty is particularly fiendish: The malware first contacts its master’s control server, which generates a new public-private 2048-bit RSA cryptographic key pair and sends the public half to the malware.

Then for every file discovered on the computer, Cryptolocker generates a new 256-bit key and uses it to encrypt that document using the virtually unbreakable AES256 algorithm. That AES key is then encrypted using the RSA public key and stored with the obfuscated document.

Only when the victim pays up does the Trojan download the private half of the RSA key, which is used to decrypt the per-file AES keys and ultimately restore all the protected documents. Targeted files include anything with .doc, .docx, .xls, .xlsx, .ppt, .pptx, .dwg, .dxf, .dxg and .jpg extensions and plenty more.

So all your Office files, all your Photographs GONE!!! Unless you pay.

NEVER click HYPERLINKS in Emails: If you  need to visit your bank site. Paypal ec, type in the URL manually the very top bar in your browser

Please ensure ALL your staff and co-workers, Friends & Family know this risk, its LIVE right now and expected to hit more throughout the week!
There is NO way to FIX what this virus does, it cannot be undone without PAYING, so it is vital that you ensure your backups are working and you have a backup NOT connected to any PC too!

Hit SHARE to post to Facebook, Twitter etc

Users are urged to maintain regular backups of their data, kept separate from their computers, as the encryption is essentially uncrackable, and consider using tools to thwart the software nasty. The Trojan infects systems running Windows 8, Windows 7, Vista, and XP.

I started on computers back in the days of the Sinclair ZX81 and Spectrum, back when people were coming to terms with how great their new digital watch was. Even though I worked in DIY Shops, Fancy Goods, the building trade, DJ’ing etc, my main interest and passion was always in coding, graphics and games. I decided to take the plunge into computer shops in the mid 90’s and in 2003 set up my own computer business.
I have a simple work ethic which is I prefer to make a little money often, rather than charging a fortune and losing customers. This has proven to work for me and my customers. In all the years I have traded I have never advertised and yet each week, I get new customers through recommendations – there is no higher praise :)
