Fourteen Ways to Read the PID for the Local Security Authority Subsystem Service (LSASS)

Process enumeration is necessary prior to injecting shellcode or dumping memory. Threat actors tend to favour using CreateToolhelp32Snapshot with Process32First and Process32Next to gather a list of running processes. And if they’re a bit more tech-savvy, they’ll use the NtQuerySystemInformation system call directly.

Although this post will focus on obtaining a PID specifically for LSASS, the methods described here can be adapted to resolve PIDs for any process. Some of these are well known and have been discussed before, but there’s also a few new ones that many readers won’t be familiar with…

SQUIP: Exploiting the Scheduler Queue Contention Side Channel

In this paper, we present the SQUIP attack, the first side-channel attack on scheduler queues. With SQUIP, we measure the precise degree of Scheduler Queue Usage (i.e., occupancy) via Interference Probing. We show that this occupancy level measurement works on microarchitectures of different vendors, namely the Apple M1, AMD Zen 2 and Zen 3…

TLDR - Do not buy, do not use, and remove all of these devices from service immediately (IPC-3605N and the model IPC-4605N). They are so miserably insecure it took me less than a day of effort to develop a utility to remotely compromise any of them. Keep reading if you want to know how… (from Author)
