⚠️ want a highly impactful, actively exploited border gateway zero days situation to wake you up?

Ivanti Pulse Secure aka Ivanti Connect Secure and Ivanti Policy Secure Gateway customers - prepare to deploy mitigations and await follow on patches.

In the wild exploitation, probable nation state - includes authentication (including MFA) bypass and code execution.

Looks like Ivanti have done a really good job identifying.

I call it ConnectAround. #threatintel #connectaround

It's really widely used in enterprise space and government, so I would suggest it's one to get skates on and may need a bunch of compromise assessments at larger orgs.

Obvious point - there will likely be more #ConnectAround victims.

Most orgs don't have the capability to detect suspected zero day exploitation of a VPN and call in Mandiant IR... they probably have Bob The Builder as an MSP and a security budget of 4 twigs.

@GossiTheDog I get at least 5 twigs, and sometimes a pile of dirt!

You're so rude.

@GossiTheDog Sometimes they spit in the dirt to remind me how good I have it for being the only security SME and also doing my standard T3 ops work.
