BlockThreat - Week 3, 2025
Sony | UniLend | The Idols NFT | PIKA | BIGO | GraFun
Greetings!
This week saw a handful of hacks totaling just under $700K in losses. A notable trend is emerging in on-chain exploitation: the BSC chain has essentially become a hunting ground for bad actors targeting small TVL projects. These attackers even send messages congratulating one another for being the first to discover and exploit vulnerabilities.
Despite this trend, the majority of losses still originate from the Ethereum mainnet, which continues to attract serial exploiters. For example, the $200K UniLend hack not only caused significant damage but also inspired several copycat attacks.
In other news, Sony experienced a hard lesson in decentralization. Their attempt to censor tokens and transactions on their sequencer backfired when it became evident that transactions could still be submitted directly through L1.
Oh and be sure to check out a great new podcast for bug hunters in the Media section below. Let’s dive into the news!
