WatchGuard Technologies' Second Quarter 2023 Internet Security Report highlights top malware trends and threats to network and endpoint security. The analysis by researchers at the WatchGuard Threat Lab revealed, among other things, that 95 percent of malware is transmitted via encrypted connections…

The MOVEit vulnerabilities may have been patched by now, but the APT group CLOP is just getting started with its blackmail. A total of 52 names of companies that CLOP claims to have attacked via the MOVEit vulnerability have been published - for some even the first data packages or the entire data booty. Somehow the CLOP group doesn't quite believe its Robin Hood demeanor: the APT group only claims to take money from big companies. The captured data from public and government agencies had already been deleted because the group was not interested in politics. However, some experts are of the opinion that…

Ransomware: Each payment funds 9 new attacks

New research from Trend Micro reveals how the ransomware industry is staying alive. A new study shows how cybercriminals operate and finance their activities.

The study contains strategic, tactical, operational and technical information on threats. Data science methods were used to compile various information about threat actors. These data and metrics help to compare groups of ransomware, assess risk and model the behavior of threat actors. A paying…
