Today someone stole 3,600lbs (1632kg) of Gold from the Toronto Pearson Airport. It is valued at roughly $100,000,000.

The police currently have no suspects. Unrelated to malware of course, but such a ballsy heist is impressive.

ALPHV ransomware group modus operandi has changed. The recent victim postings tone has changed significantly. They do not come across as calm and professional as ALPHV traditionally has.

Someone is new to their group and much more vocal.
