Is your Cybersecurity Canoodling with a Zero-day? It’s Time to Update!

In the soap opera that is cyber security, Barracuda, one of the leading protagonists, found themselves in quite a pickle. Some sneaky rascals by the fancy code-name UNC4841 (sounds like some hidden treasure, doesn’t it?), seemingly based in China, found a zero-day vulnerability to play with. It’s like leaving the backdoor open while going for a vacation and a burglar finds out.

This nasty little bug, sensationally tagged as CVE-2023-7102 (no, it’s not the next Star Wars droid), was feasting on Email Security Gateway (ESG) appliances. Sounds like somebody forgot to install the antivirus on their cyber-toaster, right?

Luckily, our cyber-heroes at Barracuda quickly swing into action with a barrage (get it? Barracuda? Barrage?) of patches starting from December 21. However, what’s the lesson here? Keep updating, my friends! Updates might be annoying, but it’s better than having your cyber-toaster held hostage by a group seemingly auditioning for the next Mission Impossible movie!
