/ Hijacking email with Cloudflare Email Routing

Cloudflare Email Routing was in closed beta back when I discovered this vulnerability, with only a few domains having been granted access. Sadly, I was not invited to the party, so I was simply going to have to crash it instead.

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…

/ Notice about Slack password resets

On August 4, 2022, we notified approximately 0.5% of Slack users that we reset their passwords in response to a bug that occurred when users created or revoked a Shared Invite Link for their workspace. When a user performed either of these actions, Slack transmitted a hashed version of their password to other workspace members. This hashed password was not visible in any Slack clients; discovering it required actively monitoring encrypted network traffic coming from Slack’s servers. This bug was discovered by an independent security researcher and disclosed to us on July 17, 2022. It affected all users who created or revoked Shared Invite Links between April 17, 2017 and July 17, 2022.
