BlockThreat - Week 35, 2023
Infamous Chisel | BitBrowser | AppSocial | Sui
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.
