Brazilian Developers Recover $200K Stolen Crypto in 5-Month Effort

A group of Brazilian developers, led by Afonso Dalvi from Web3 startup Lumx, have successfully recovered over $200,000 worth of cryptocurrency stolen from a victim's wallet by an exploiter using flashbots and scavenging bots. The recovery effort, which took around five months, involved close collaboration with public prosecutor Alexandre Senra and his assembled task force.

The victim initially contacted Senra after discovering the theft from their wallet. Senra then reached out to Dalvi and the Lumx team for their expertise in tracking and recovering the stolen funds. The process began with convincing the victim to share their private key, a critical step in enabling the developers to access the compromised wallet and initiate the recovery process.

Dalvi and his team developed a specialized flashbot to capture the stolen funds once they were released from the DeFi protocols where the exploiter had deposited them. They also employed a scavenging bot to track and recover the daily yield generated by the locked funds. The developers had to apply sophisticated MEV (Miner Extractable Value) tactics to successfully capture the funds after the release process.

Why this matters: This case highlights the growing collaboration between law enforcement and the Web3 community in combating cryptocurrency theft and exploitation. The successful recovery of stolen funds demonstrates the effectiveness of specialized tools and expertise in tracking and retrieving crypto assets, offering hope to victims of similar crimes.

Despite the exploiter being a seasoned on-chain operator, the Brazilian developers' persistence and technical skills ultimately prevailed. The case serves as a testament to the increasing efforts to combat cryptocurrency crime and the importance of cooperation between authorities and industry experts in the Web3 space.
