@avuko aye. we're not seeing anything yet in the fleet and i was gonna ask our pals @ Censys what to query today but honestly if folks have mongo exposed, it's not worth asking Censys folks to pause their holiday festivities.

time to burn it all down?

Thanks to this share β€” masto.deoan.org/@neurovagrant/ β€” I now have an C-backed package {roast} for decoding OAST domains (which shld help nail down some campaigns better @ $WORK).

Never bothered to look into OAST before b/c we weren't extracting payload stages and I cld not care less about bug bounty hunters.

Gotta make a DuckDB SQL function for this now.

Curious to learn what good blogposts/threads you read on pivoting and APT operations this year that you found enlightening.

Trying to do the pivoting a bit more and while this is pretty easily doable for DPRK-related actors these days, imho, I am sure there's has been much I've missed.

anything JA4-related (blog.foxio.io/ja4+-network-fin) or using openly available tools to find stuff that's being hosted on github/gitlab etc especially of interest

@hrbrmstr @neurovagrant actually, much further than that. Security should be advising their NetEng teams to filter all routes announced by AS152194 at the border.
They are not just announcing bogons but also hijacks.

@neurovagrant after poking at the probe-then-payload patterns, this is an extremely well-coordinated initial access broker mass exploitation campaign designed to run when there were skeleton crews in SOCs.

AS152194 shld be perma-blocked by everyone.

@hrbrmstr here's partial-but-voluminous DNS records for the oast.tld's in the list seen in the last 30 days. (zip with CSVs)

A couple of them maxed out on the UI and I am not CLI-caffeinated yet. Will hunt more once I'm not a zombie.

@neurovagrant if it was/is an infosec vendor, they will be ripped many new ones, given some of the payloads did immediate data breaches on unpatched servers/apps/devices.

This is a super well-orchestrated recon (and RCE attempts) campaign.

Nearly 10K OAST domains (updated in GH β€” github.com/GreyNoise-Intellige β€” cc: @neurovagrant ) expertly used across scores of tags in a very compressed time window.

They likely used ProjectDiscovery tooling but did it really well.

Folks better check logs after the break.
