Today, I'm releasing the first version of a small web 🚀: rosti.bin.re
It provides IOCs and YARA rules collected semi-automatically from public blog posts and reports of almost 200 cybersecurity sites.
I hope it proves useful to some of you ... 🙏✨ #ThreatIntel

This hack is brilliant, APT28 hopping into a target environment over wifi by compromising neighbouring companies and finding a dual-homed host within range.

And yet... they got caught doing this!

@david_obrien @mrcoups @CrowdStrike Yes, we have seen it take up to 15-20 reboots until you are lucky to get the updated file and problem is solved.
English
@mrcoups @CrowdStrike There are legit reports saying that repeated reboots might fix it.
English
The fix from @CrowdStrike so far is to login to individual servers to fix the issue, if you’re in the enterprise, today is not a great and you have a long weekend coming up. Please remember your sysadmins today!
English
@x0rz What about disk-encrypted systems, ie with Bitlocker etc?
English
> PXE boot on a system-rescue.org image
> ssh into every workstations/servers
> remove faulty .sys file
> reboot normally
> CrowdStrike updates
> ???
> profit and see you on monday

@vmesc4pe @_JohnHammond We do the same. Its great for automated flows and sharing, all machine-to-machine stuff, and as a database. But we use other tools to actually do the daily job, like OpenCTI and self developed things.
English
@_JohnHammond All of the above. We store every ioc we come across and use it to enrich our detections and IR tooling, then share ioc data with other government misp instances. Hooks up to DFIR-IRIS quite well too
English
CTI/DFIR people. If I may please prod your mind.
Do you actually use MISP?

A friendly reminder that you are indeed responsible for backups even when using someone else’s data center.
Scott Piper@0xdabbad00
Google Cloud accidentally deleted a company's entire cloud environment (Unisuper, an investment company, which manages $80B). The company had backups in another region, but GCP deleted those too. Luckily, they had yet more backups on another provider. theguardian.com/australia-news…

@adbertram Great one! Had no idea.
Is there one for DomainNames.tld too? 😀

#PowerShell tip of the day: Use the [ipaddress] type accelerator to quickly parse and validate IP addresses.

@tmels ohhh thank you, had missed that possibility! Will be a great extra project to work on.

Has anyone seen any way to visualize for Corp Users any changes IT does to o365/EntraID/Intune?
Im dreaming of an internal website showing anything that has changed, showing any new apps, policy changes etc etc

Which group of 'people' did this atrocity?
What are you doing to resist this evil group?
Do you have co-workers who support these war crimes?
Do you work in a place that supports these war crimes?

I highly suggest everyone in #CTI to check out the community version of @ValidinLLC.
Free availability of historical DNS data going several years back is absolutely amazing to have at hand.
I use this tool several times a week during my investigations, with great success.
Validin@ValidinLLC
It's here - our long-awaited update is out! This update builds on our massive passive DNS database and is packed with features requested by the community. ❤️ If you're a threat hunter or researcher, this platform is made for you! validin.com/blog/announcin…

This 👇 is interesting and suggests that we can't anymore consider only the possibility of a common initial access broker #IAB in case of one victim claimed under more than one #ransomware brand.
I've counted 88 cases of cross-claims since Jan. 1st, 2023. Let's take a look...

🌐 On the last day, Lockbit #ransomware group announced sixteen new victims despite operation #Cronos 🚨 More than five of the victims are companies that were already been #compromised by BlackCat (ALPHV) team, whose website was allegedly shut down by law enforcement 👀 #Lockbit with a total of 2533 victims 🥇 ➡️ More Info: DARKFEED.IO #BlackCat
