gmazurat March 05,2015 Straight forward demonstration on how cryptolocker malware can ruin your day. Be warned, using security software based off of signature analysis is not the complete solution to averting cryptolocker malware. Common sense safe computer use including the use of off net back-ups, cloud back-ups, and encrypted files are among some of the other countermeasures used to avert such attack. Plenty of good ideas available on the Internet. Google “cryptolocker countermeasures”.
nbodykat March 10,2015 A couple weeks ago NBC news did a story about viruses encrypting a person's files and having to pay a ransom to get access back. One of the victims was a police department who needed the evidence for several trials so they paid the ransom. This is also a good argument for having backups of your files. I backup everything on my personal laptops. If I was hit with this, I can always recover from it. I do backups frequently and there is nothing on my personal computer that would make me pay ransom to get it back because I have a backup. That being said this video is a good argument for keeping your anti-malware and security software up to date. My program updates almost daily with the latest malware signatures. Additionally, I update my applications frequently because I read a report where 80% + of the attacks against organizations were successful because that organization neglected to keep their anti-malware software and applications up to date and neglected to implement a patch management and update program. My advice besides keeping your applications up to date is to also do backups of any important files you can't live without.
Ahmedat March 21,2015 using Antivirus is quite useful but i think educating users and clients about those nasty malware is the most important because you can always get a malware that's not recognized by the antivirus system.
connellytat March 23,2015 Sophos has a decent write up of Cryptolocker as well. This one talks about how much money the operator have been estimated to get from it. It also talks about how it was used in conjunction with Gameover Zeus, and when the FBI took down the GOZ command and control servers, it also took down the cryptolocker control server as well. https://nakedsecurity.sophos.com/2014/06/03/has-cryptolocker-been-cracked-is-gameover-over/
