The shady world of ransomware extortion is experiencing a significant upheaval as researchers notice a surge in attacks from PYSA ransomware. It has been found that the relatively new ransomware was behind 50% of attacks that occurred in November. In another concerning revelation, threat actors have created a new exploit that bypasses the patch for the MSHTML remote code execution flaw.
