BlockSec Thwarts Flash Loan Attack on Usual Protocol, Prevents Asset Loss

• Real-time defense by BlockSec’s Phalcon prevented a complex DeFi exploit on Usual
• Multi-stage attack involved flash loans and contract manipulation but was blocked early
• Usual incident highlights rising need for automated security in cross-chain DeFi protocols

A sophisticated hacking attempt on the Usual Protocol was stopped in its tracks thanks to real-time detection by BlockSec’s Phalcon system. The attack, which unfolded on May 28, targeted the decentralized stablecoin platform across multiple blockchains. 

Usual, known for its fiat-backed token infrastructure, paused operations temporarily to assess the situation. BlockSec revealed that its intelligent security system intercepted the attack before any assets were lost. This swift response marks a growing trend of DeFi protocols turning to automated tools for constant protection.
