In October of 2013, Antivirus companies discovered a new ransomware known as Cryptolocker. Since then, after many attempts at blocking and killing the software attacks, a new version came out, and both are “seized” according to Deputy Attorney General James Cole. The leader, Evgeniy Bogachev, is even wanted by the FBI. Whenever one attack is stopped, there is almost always another that is stronger and less detectable than the last. Here is the low-down on ransomware.
What is Cryptolocker Ransomware?
Ransomware is a type of malware which restricts access to the computer system that it infects, and demands a ransom paid to the creator(s) of the malware in order for the restriction to be removed. Cryptolocker ransomware is particularly nasty because infected users are in danger of losing their files… forever.
These messages have been targeted to businesses through phishing attacks. The only way to unlock your files is by using a private key stored on the cybercriminal’s server. Infected users must pay $300 USD to receive this private key. There is also a time limit placed on this, if you exceed it, you’re files could be lost forever.
Here is a list of file extensions that are targeted and encrypted so you can’t access them after attack:
3fr, accdb, ai, arw, bay, cdr, cer, cr2, crt, crw, dbf, dcr, der, dng, doc, docm, docx, dwg, dxf, dxg, eps, erf, indd, jpe, jpg, kdc, mdb, mdf, mef, mrw, nef, nrw, odb, odm, odp, ods, odt, orf, p12, p7b, p7c, pdd, pef, pem, pfx, ppt, pptm, pptx, psd, pst, ptx, r3d, raf, raw, rtf, rw2, rwl, srf, srw, wb2, wpd, wps, xlk, xls, xlsb, xlsm, xlsx

How do you protect yourself?
When you see the message like the one shown above, it’s actually too late. You need to prevent ransomware before it starts.
First off, be aware of how to identify malicious emails in your inbox.
Second, make sure you have a program on your computer that blocks these types of attacks. Losing access to all your files can be detrimental for your business. Protect yourself and your client’s information that is stored on your computer by investing in an anti-malware software. FlexTech offers programs that will both protect against ransomware, and help to recover files in the unfortunate event you are attacked.
