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. volexity.com/blog/2024/11/22… And yet... they got caught doing this!

Windows 11's new AI Recall feature raises security concerns. Therefore, check this KQL hunting query (see below) designed for Microsoft Defender for Endpoint users to detect any activations of AI Recall on your network which has been created by Steven Lim. #ThreatHunting

A friendly reminder that you are indeed responsible for backups even when using someone else’s data center.
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-ne…

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.
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/announcing_…

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

I've developed a new Red-Teaming tool called NoArgs. It dynamically hooks into Windows APIs to manipulate and hide process arguments. By injecting it into a cmd process, it hides the arguments of every newly spawned processes at runtime, without leaving traces for logging applications that rely on information from the Process Environment Block (PEB). Source and detailed info: github.com/oh-az/NoArgs

CISA is requiring all Federal agencies to disconnect Ivanti products by Friday at midnight (Ivanti Connect Secure & Ivanti Policy Secure). This is roughly 48 hours notice, to not patch, but rip it out! Ivanti is an American company. This is unprecedented. cisa.gov/news-events/directi…

During incident response it is easy to focus only on the technical issues, but IR is as much a people problem. Microsoft DART have released a downloadable interactive playbook to help navigate those problems through practical and people-focused guidance - microsoft.com/en-us/security…

So, Mike Brutman (mTCP author) has created something new & cool: a utility that allows you to mount an image on a modern Linux or Windows system, and access the files from a DOS machine! And since it is TCP, you can even mount an image over the internet! brutman.com/mTCP/mTCP_NetDri…

…what. I don’t know what to say about this one. Is this a first? It appears that the ALPHV (BlackCat) ransomware group has…filed an SEC complaint on behalf of one of their victims. Are we entering into a new era of extortion via compliance failure? I have questions…
