Ransomware is not going anywhere: Attacks are up 24%

Avast released a report revealing a significant increase in global ransomware attacks, up 24% from Q1/2022. Researchers also uncovered a new zero-day exploit in Chrome, as well as signals how cybercriminals are preparing to move away from macros as an infection vector.

Conti members have now branched off to create new ransomware groups, like Black Basta and Karakurt, or may join other existing groups, like Hive, BlackCat, or Quantum, causing an uptick in activity.”

Zero-day exploits

Researchers discovered two new zero day exploits used by Israeli spyware vendor Candiru to target journalists in Lebanon, among others. The first was a bug in WebRTC, which was exploited to attack Google Chrome users in highly targeted watering hole attacks, but also affected many other browsers. Another exploit allowed the attackers to escape a
