The cybersecurity meganews of the week is anything to do with HAFNIUM. Hafnium is the name Microsoft uses to denote a specific gang of cybercriminals, allegedly operating out of China via cloud services in the US. The newsworthy of this cybergang right now is that they have been connected with a number of brand new exploits recently patched in Microsoft Exchange systems. These zero-day bugs can be used, amongst other things, to get access into, and to implant malware onto, Exchange systems, giving crooks a sneaky entry pathway that avoids the need for cracked or guessed passwords.”]
