It has been two weeks since the National Communications Association warned the world about the GameOver Zeus and Cryptolocker ransomware, and if you haven't taken steps to avoid these threats, it's not too late - if you haven't been infected yet, do so as soon as possible. Otherwise, your network will be vulnerable, and so will your banking credentials.
About Cryptolocker and GameOver Zeus
GameOver Zeus is said to be the reason for the massive spread of Cryptolocker, having infected more than 15,500 computers in the UK alone at the present moment. The peer-to-peer software used by GameOver Zeus looks for bank login credentials to steal sensitive information. If this malware doesn't find anything of value on your computer, it will then proceed to install Cryptolocker, a type of ransomware that will lock down your PC's hard drive and charge you a decryption fee. Cryptolocker utilizes a third-party certified cryptography software that conforms to Microsoft's CryptoAPI, and thus is very difficult to get around without paying the fine. The ransomware locks down files on your computer, limiting what you can access. You are given a timeframe before the malware encrypts everything on your system. In other words, this is one of the worst threats we've seen in a long time.
What to Do to Protect Yourself
Here are some security tips from NetWorthy Systems to help you keep your computer safe.
You should print this page in the event that your computer has been locked down so you may best combat this dangerous malware. However, if you have only been threatened by the ransomware, do not pay it.
If you see this screen, take the following actions toward limiting the impact that the malware has on your system.
NetWorthy Systems will attempt a system backup restore using your backed up files, provided they aren't infected (and you have one). At this time, there is no way to decrypt files without the decryption key.
If your computer has been locked down by Cryptolocker, as previously mentioned, it is extremely difficult to crack, and downright impossible for the average computer user. Don't let the crooks responsible for this malware push you around. Contact NetWorthy Systems today if you have any concerns about this threat.
