You have probably seen a lot in the news recently about 'cybercriminals' and have concerns over how this will affect your small to medium-sized business. We will likely post more on this in future, so they are in bite-size chunks, but for now, see some information below and what you can be doing to protect your business. As the BBC reports in reference to the image here, "Evgeniy Bogachev, said to be known as "lucky12345" and "slavik", is accused of being involved in attacks on more than a million computers."
What are Gameover Zeus and Cryptolocker?
Gameover Zeus is used by cybercriminals to intercept transactions during online banking sessions and Cryptolocker is a form of ransomware, which works by encrypting files on the victim’s hard-drive, then demanding payment for the key to decrypt (so asking for payment so that you can remove it).
The UK National Crime Agency and the FBI, working with anti virus software venders, were able to significantly disrupt two financial malware operations: Gameover Zeus botnet and Cryptolocker ransomware network.
