Every 4.2 seconds a new malware specimen emerges to threaten the safety and security of your business. The Sangfor security team, dedicated to keeping you informed of any new potentially dangerous variants, recently discovered that the ransomware Globelmposter has been updated to version 3.0. This comes close on the heels of last week’s notice of a new Globelmposter 2.0 variant. Globalmposter 3.0 infects systems and encrypts database files, appending encrypted files with .Ox4444 and requiring victims to contact hackers through email to negotiate ransom and get the decryption key.

With several large Chinese hospitals experiencing recent attacks, Sangfor reminds customers to be wary of GlobeImposter and all its variants.
