Kovter malware upgrade takes it from mild to mean
Hackers are upgrading already planted Kovtermalware with the goal of gaining broad access to Fortune 500 computer networks.
Cybereason Lab found hackers are placing the click-fraud and adware tools on corporate systems and then upgrading the software into more malicious forms of malware capable of grabbing control of a network or important company assets, the research firm wrote.
Cybereason Lab pointed out that one reason this tactic is so dangerous is because most companies consider click fraud and adware low-risk threats and more or less dismiss them, particularly compared to zero-day attacks and ransomware.
