BlockThreat - Week 5, 2023
T-Mobile | Bonq | Orion Protocol | SperaxUSD
Unfortunately my predictions of major hacks dropping a few weeks of quiet were true. Where to begin? T-Mobile was breached, again. The compromise also affects 3rd party providers such as Google Fi and Mint which used their network. So if you their customer, it is now time to change your password and be on the lookout for signs of phone porting. On the DeFi side we had a $120M Bonq exploit which was relying on a cheap to manipulate price oracle and Orion Protocol with a good ole’ reentrancy.
On the more positive side, FBI briefly changed their profile picture with a seized BAYC thanks to the tip by ZachBXT.
Hope you stay safe out there. Let’s dive into the news, but first a really interesting note from our sponsors at Chainalysis on how the bad actors launder stolen assets!
$23.8B in Crypto Laundered in 2022 (up from $14.2B last year 🤯)
Money laundering is critical to all financially motivated crime—it enables criminals to cash out from their nefarious activities without being detected. We’re seeing the majority of laundering activity happen at fiat off-ramps like centralized exchanges, though we’ve also seen a big spike in underground money laundering services touting brand names and sophisticated infrastructure.
