Cisco Firewall Fiasco: How Vulnerabilities Are Turning Secure Networks Into Swiss Cheese
Cisco firewall vulnerabilities are under attack by an “advanced threat actor,” causing cybersecurity agencies to sound the alarm. The flaws allow attackers to implant malware and execute commands. CISA demands immediate patching, while Cisco faces scrutiny for its delayed response. Cybersecurity: where zero-day is the new normal.

Hot Take:
Well, well, well, it seems like Cisco’s firewalls are more like Swiss cheese – full of holes, and not exactly the kind you want around your data. The advanced threat actor seems to be having quite the field day exploiting these vulnerabilities, and it’s clear Cisco’s firewalls are letting more through than a sieve. Time to patch up, or these devices might as well be used as doorstops.
Key Points:
- Critical vulnerabilities in Cisco’s ASA and FTD devices are under attack from an advanced threat actor.
- CISA issued an Emergency Directive urging immediate action within 24 hours.
- UK’s National Cyber Security Centre also stressed the importance of patching these vulnerabilities.
- Cisco knew about the exploitation since May, but it took months to sound the alarm.
- The vulnerabilities are linked to the ArcaneDoor campaign, suggesting state-sponsored espionage activities.
