Hey #infosec and #cybersecurity folks. I have a couple thinky questions I'd like to get perspective on: - What makes a "good" cybersecurity partner in this day and age? - What services or capabilities are table stakes for you? always curious what you folks are seeing or would like to see

Random Monday thoughts… As most of us have come here to find a safe haven from extremism, I feel it’s important not to use this sanctuary to intentionally sow further division. Paraphrasing Ram Dass, “individualism leads to war, anger, insecurity, and fear.”

This git is full of resources for event logs/auditing. Covers everything from tool configs to audit cheatsheets to event attack chains and data samples. In #DFIR visibility is key. This is a solid resource for those responding to an incident or trying to prevent one. #grc github.com/stuhli/aweso...

Vulnerabilities from 2021 still haunt orgs. When I respond to attacks where these have been exploited I commonly hear "We were just about to upgrade that server next quarter." Yesterday's threats may still present risks today. Focus on asset and vulnerability management.. among other things.

3 years later log4j vuln is #8 most exploited. The hype was justified. Also, why are people still using vulnerable versions and still not updating? www.cisa.gov/news-events/...

Determining how a process interacted on a Linux host can be a hassle without the data laid out in front of you. The goal of the ProcFD output is to provide the analyst structured data for quick sorting, making the analysis of running processes more efficient. #linux #dfir

The response for this artifact has been overwhelmingly positive. I wanted to provide a screenshot of the output to illustrate the value to those who haven't had a chance to tinker. The ability to sort the filesystem output based on timestamps can be very helpful during an investigation. #dfir #linux

It's no surprise, credential reuse from infostealers is fueling authentication attacks. Our researchers at Talos detailed findings around a new campaign targeting education and government orgs, PXA Stealer. blog.talosintelligence.com/new-pxa-stea... #threatintel #infostealer #talosthings
