LOL at the idea of someone paying money to Cisco for email software and/or appliances.I don’t victim-blame, so all I can say is: do not do that and thanks for the giggle. @… https://
Kevin Beaumont (@GossiTheDog@cyberplace.social)Cisco have found an in the wild zero day in Cisco Secure Email Gateway And Cisco Secure Email and Web Manager being used to backdoor appliances for later access. Now CVE-2025-20393. No patch available. They recommend nuking boxes and reinstalling from scratch if you opened spam quarantine port (6025 and 7025) to internet, and closing port. It is unclear how long boxes have been backdoored for. Ports aren't scanned by @shodan@mastodon.shodan.io yet so scope isn't known. https://sec.clouda…
