The Good, the Bad and the Ugly in Cybersecurity - Week 45 (2026)
SentinelOne, Friday, November 6th, 2026
SentinelOne's week 45 roundup: investment scam takedowns, Teams help desk impersonation with AD CS abuse, and European fridge attacks.
SentinelOne's weekly roundup covers three main stories.
The good: European police with Europol and Eurojust arrested seven suspects and seized over 100 servers behind an investment fraud service, the US indicted two Canadians for hacking universities to mine cryptocurrency, and Russian police arrested three suspected VasyGrek members.
The bad: attackers posed as IT help desk staff on Microsoft Teams, used Quick Assist to gain access, then abused misconfigured Active Directory Certificate Services templates to obtain persistent privileged certificates.
The ugly: a second wave of attacks altered internet-exposed refrigeration controllers at retailers in six European countries and at French blood bank cold storage, likely through exposed interfaces and weak default credentials.
