Symantec Unmasks Black Basta’s Sneaky Exploit: Did Microsoft’s Patch Miss a Zero-Day?
Symantec’s threat hunters suggest Black Basta ransomware gang exploited a Windows zero-day bug before it was patched. Microsoft fixed the flaw in March, but evidence indicates the gang may have used it earlier, potentially achieving full system control. This highlights the ongoing cat-and-mouse game between cybercriminals and security experts.

Hot Take:
Looks like the Black Basta gang found a way to exploit a Windows bug before Microsoft could say “Patch Tuesday!” If only they used their powers for good—like fixing printers or making Clippy useful again.
Key Points:
- Symantec suspects Black Basta exploited a Windows privilege escalation bug before it was patched.
- Microsoft patched the flaw, CVE-2024-26169, in March.
- The bug could allow attackers to gain SYSTEM-level access.
- Symantec’s analysis suggests the exploit was used before the patch was issued.
- Microsoft’s Quick Assist application was abused in similar attacks by the same gang.
