The leaked Babuk Locker ransomware builder tool has finally made headway for a new attack campaign. An anonymous threat actor has been found using the leaked builder tool in a very active campaign that targets victims worldwide. The new ransomware variant, named after ‘Babuk Locker’, encrypts files on victims’ systems and later drops a note demanding a ransom of 0.006 Bitcoins.

Cybersecurity analysts are also warning of another ongoing cyberattack conducted by a China-based IndigoZebra threat actor group. The attackers are leveraging Dropbox to infiltrate the Afghan National Security Council (NSC) and drop a backdoor dubbed BoxCaon. The malware is capable of stealing confidential data.

The Windows SMB server is also under attack by the NSABuffMiner worm. The ultimate goal is to drop cryptominers on compromised machines.
