Greetings!

A relatively quiet week to wrap the month with significantly less losses ($25m) relative to July ($462m). I guess web3 blackhats take time off too. The largest compromise was of BitBrowser users who enable a sync feature lost $520,000+ worth of crypto after the browser backend infrastructure was compromised.

Things are more concerning on the malware side with more information released by GCHQ about the Infamous Chisel Android malware associated with the infamous Sandworm Russian APT group. The malware is a credential and crypto stealer targeting major wallet software.

To gain access to comprehensive vulnerability write-ups, post-mortems, exploit proof of concepts (PoCs), attacker addresses, and additional data regarding this week’s compromises, please subscribe to the premium plan below.

Quiet weeks like these are much needed for all of us to catch up on research and tools, so I hope you will find time to read up on research and tool release in this and previous editions of the newsletter!
