The Citizen Lab Bad Connection: Uncovering Global Telecom Exploitation by Covert Surveillance Actors Our investigation uncovers two sophisticated telecom surveillance campaigns and, for the first time, links real-world attack traffic to mobile operator signalling infrastructure. The findings expose how suspected commercial surveillance vendors (CSVs) exploit the global telecom interconnect ecosystem, leverage private operator networks, and conduct covert location tracking operations that can persist undetected for years. https://citizenlab.ca/research/uncovering-global-telecom-exploitation-by-covert-surveillance-actors/ 🎖@malwr

Inside the Falcon How CrowdStrike Catches You A full reverse-engineering teardown of the CrowdStrike Falcon sensor: the six kernel callback sources, the WFP network engine, the file-system minifilter, the cspcm4 broker, the user-mode service (DNS / AMSI / browser / Identity Protection), and the cloud-loaded detection engine — plus every structural blind spot.

Your executable is a SQLite database I have been probably obsessed with two things in the last few years: Nix as a tool to explore innovative ideas that require the capability to rebuild the world and replacing ELF with SQLite as an executable format. You might have noticed that these two ideas are well suited to each other. https://fzakaria.com/2026/08/23/your-executable-is-a-sqlite-database 🎖@malwr

SLEEPWALKER: A Passive Backdoor With Its Own Command Language Losing access to VirusTotal Intelligence at the start of the year was surprisingly productive. Unable to hunt for interesting new malware, I stopped adding to my “TODO” pile and finally worked through my backlog from last year. That led to a detailed examination of BeheMOF as well as the discovery of this malware. Upon closer inspection, a sample that did not seem too noteworthy at first turned out to have a distinctive design once I looked under the hood: a passive backdoor that opens no obvious listening port and carries no payload inside itself. It waits in memory doing nothing at all until one specifically crafted network packet reaches the machine, which is why I am calling it SLEEPWALKER. https://r136a1.dev/2026/08/24/sleepwalker-a-passive-backdoor-with-its-own-command-language/ 🎖@malwr
