Today's newsletter covered all the Cisco IOS XE drama, on how it unfolded and how attackers began to hide infected devices: https://mastodon.social/@campuscodi/111283390046046356 As Fox-IT explained today... it isn't a law enforcement takedown or a white-hate. It's the attacker. They've added an authenticator in front to prevent fingerprinting. There's still 37k infected Cisco routers around. They didn't go anywhere: https://twitter.com/foxit/status/1716472673876730149

Abusing gdb Features for Data Ingress & Egress · Arch Cloud Labs
About The Project Modern Software Development environments have significant debugging capabilities to troubleshoot issues with the complex nature of modern software . These debugging capabilities typically manifest in Interactive Development Environment (IDE) as features that extend an IDEs capability to examine the given state of an application at run time or analyze previous binary executions.

If it weren’t for public PoCs I probably would have never learned modern exploit dev. Also speaking from personal experience, publishing techniques shortens their lifespan. By a lot. https://t.co/E1j26QJisB

Summary:

✅Yes PoC helps bad people do bad things faster
✅Defenders need the PoC more than the attackers do, even though both sides are helped by its release
✅Giving defenders even slight edges over the majority of criminal attackers is net good
✨Non disclosure is far worse
What?!? It seems like spying for China is the least problematic part of this tradition.

Releasing an exploit proof of concept is a hot debate. Some argue it’s educational, but it can also empower malicious actors. We see bulk exploitation rates explode after, but advanced compromises against key victims don’t change a lot. What’s your take? pic.twitter.com/nO4bPuAsGc
