…by holding your operating system hostage.
Ransomware has become the most common form of malware over the past few years. Typically ransomware encrypts your key files and the attacker demands payment, however it is expected that variants will begin to emerge that are designed to modify the infected computer’s Master Boot Record. This will cause the system to boot to a lock screen demanding payment before the attacker will decrypt files and restore access to the main operating system.
Multiple layers of defense are required to counter ransomware. Strong network controls and access controls are very important, however user awareness and training is just as critical to prevent social engineering that allows an attacker to deliver the malware. Finally, always backup your data AND your operating system. In many cases, if you detect the ransomware in a timely manner, you can wipe the OS and restore from backup.
Be safe!
Good article Jason. Yes, ransomware becomes worse because attackers’ targets expand from big organizations to smaller size companies, and now to individual consumers (PC and mobile devices too). This is a sign that not enough is being done to combat ransomware effectively. This practice is becoming more and more popular. Other than backing up data and operating systems, this is an opportunity for anti-virus vendors to step up their game and create features to address ransomware in a more efficient manner.
