In September 2024, a critical minting vulnerability in multiple uniBTC vault smart contracts across eight blockchains was exploited for approximately $2 million after a third-party security firm disclosed the flaw hours before the attack. Post-incident forensics by Fuzzland, disclosed in June 2025, attributed the exploit to an insider threat — a former employee who embedded malware into Fuzzland's internal codebase and used privileged access to execute the attack; Bedrock has since integrated Chainlink Proof of Reserve and expanded to multiple new chains.","timeline":[{"date":"2024-06-12","event":"Blocksec conducts initial audit of uniBTC contracts.","source":""},{"date":"2024-09-04","event":"Alleged insider (later identified as a former Fuzzland employee) modifies Cargo.toml to include malicious Rust crate 'rands', embedding malware in Fuzzland workstations.","source":""},{"date":"2024-09-25","event":"Vulnerable uniBTC vault contract deployed approximately 36 hours before the exploit.","source":""},{"date":"2024-09-26","event":"16:00 UTC — Dedaub discovers and confirms the critical infinite-mint vulnerability in uniBTC vault contracts across 8 chains.","source":""},{"date":"2024-09-26","event":"16:27 UTC — Dedaub reports vulnerability to Bedrock via Twitter. 16:41 UTC — SEAL 911 war room created.","source":""},{"date":"2024-09-26","event":"Emergency call held between Fuzzland and relevant parties to discuss the Dedaub-identified vulnerability.
