Ransomware such as Cryptolocker and Gameover-Zeus is steadily becoming more widespread and effectively infecting corporate users’ computers. In order to help mitigate infections read through the following common practices:

1)    Ensure that Windows updates are installed when shutting down your computer. (Avoid shutting down without installing restarts; Microsoft releases Windows updates on the second Tuesday of each month, plan ahead and allow 15-20 minutes of install time if there are more than 10 updates available)

2)    Perform proper security maintenance by regularly checking whether your PC’s Windows updates are up to date, Windows Firewall is turned on and Anti-virus is enabled and updated with the latest definitions.

3)    Manage passwords effectively by using an online or local password manager with one secure master password that is changed regularly; never use the same password for multiple sites to avoid disclosure when sites are breached.

4)    Avoid clicking on suspicious links in email; don’t rely on hovering over any suspicious links either as legitimate URLs can also be spoofed to infect your computer with malware. The email method is the single most common attack vector so always pay attention to which URL / link you’re clicking on. 

5)    If you realise that your computer is infected with ransomware (screen popups, wallpaper changes etc.) disconnect its network cable / disable Wi-Fi and switch off your computer immediately and contact AddOne Support to start the troubleshooting process. Disabling network connectivity will prevent the infection from further encrypting files and folders on the network file server which is one of the attacks performed by common ransomware.
