Operation Zero Disco: When Hackers Boogied Past Cisco’s Security Patches
Cybersecurity researchers have uncovered “Operation Zero Disco,” a sneaky campaign exploiting a Cisco IOS security flaw to deploy Linux rootkits. Hackers are boogieing their way into older systems, using spoofed IPs and a universal password with “disco” flair, to gain unauthorized access and dance undetected. Update your systems, or risk a hacker dance-off!

Hot Take:
Well, it appears that some cybercriminals are taking their love of disco to new heights, as they boogie their way into unprotected Cisco systems with Operation Zero Disco. Who knew the dance floor wasn’t the only place you could catch a nasty bug? Someone needs to tell these hackers that just because it’s called a “rootkit” doesn’t mean it belongs in the ground like a tree! Cisco’s patch might have been a bit late, but at least they hit the right notes before the hackers could remix their own version of “Stayin’ Alive” on those legacy systems.
Key Points:
– Operation Zero Disco exploits a vulnerability in Cisco IOS Software.
– The vulnerability, CVE-2025-20352, has a CVSS score of 7.7.
– Attackers are using Linux rootkits and spoofed details to remain undetected.
– Cisco patched the vulnerability after zero-day attacks were reported.
– The rootkit’s universal password amusingly references “disco.”
