Gameover Zeus and CryptoLocker warning

Posted on Tuesday, June 3rd, 2014 in Cyber Security

The National Crime Agency (NCA) has given the UK public two weeks to up their computer defences.

Two forms of malware (GameOverZeus & CryptoLocker) have been attacking hundreds of thousands of users with increasing severity as time has passed. goZeus and CryptoLocker both have different methods,  however they have a singular goal; to take as much money from you as possible.

goZeus will initially connect your computer to a network of already infected machines called BotNet lies dormant within your computer system whilst you surf the web, do work, watch videos, etc. however as soon as you commit any type of banking transaction it’ll be more than ready to take your banking details and send them through BotNet where the criminals will be more than ready to leave you left with as little as they can get away with.

CryptoLocker is a little different, whilst goZeus sits and waits in the background for you to potentially slip up, CryptoLocker will sit for a little while, slowly encrypting your files one by one until you receive a notification in the form of a large window that to sum, tells you to either pay them within a given time limit (usually around $300), or have the key to your encrypted files destroyed forever.

This destructive set of malware has the potential to leave you penniless. So that’s why one of the largest law enforcement collaborations to ever take place between an active 11 countries has given the UK public these two weeks to make sure their computers have their defences up to scratch and ready for anything. The collaboration led by the FBI and fuelled by unrelenting motivation to see you secure have finally managed to break through in to command and control infrastructure and managed to bring a large portion of it down, so whilst they hold the front lines, make sure your walls are ready.
