Former Employee Behind $2 Million Bedrock Protocol Attack, Fuzzland Reveals

• A former Fuzzland employee stole $2 million from Bedrock’s UniBTC protocol using insider access and social engineering tactics. 

• Fuzzland compensated Bedrock for all damages and launched investigations with law enforcement agencies. 

• The attack reflects a growing trend where hackers target social engineering methods instead of technical vulnerabilities.

Smart contract analytics platform Fuzzland has disclosed that a former employee orchestrated a $2 million exploit targeting Bedrock’s UniBTC protocol in September 2024. The company released a comprehensive transparency report detailing the insider attack that shocked the DeFi security community.

The incident represents a significant breach of trust within the blockchain security sector. Fuzzland confirmed it has fully compensated Bedrock for all damages from the attack.

Sophisticated Attack Methods Employed

The former employee executed a complex multi-stage attack using advanced techniques. Social engineering tactics formed the foundation of the breach strategy. The attacker deployed supply chain attacks and advanced persistent threat methods to access sensitive internal systems.

The insider exploited critical vulnerability information discussed during an emergency response call. This timing gave the attacker significant advantages over external threats. The vulnerability had been previously identified in a Dedaub security report.

Malicious code insertion created backdoors across multiple engineering workstations. These backdoors operated undetected for several weeks. The extended access period allowed continuous data harvesting and system monitoring.

Fuzzland had identified the vulnerability before the attack occurred. However, the security team deprioritized the issue due to false positive alerts. This oversight created the window of opportunity that the insider exploited.

Industry Response and Investigation

Fuzzland launched an immediate joint investigation with security firm ZeroShadow. The company filed formal reports with Chinese law enforcement agencies and the FBI. International cooperation aims to prevent similar incidents across the industry.

Partnerships with Seal 911 and SlowMist focus on enhancing industry-wide security standards. These collaborations target insider threat detection and prevention mechanisms.

The attack affected Bedrock’s UniBTC product exclusively. Attackers drained $2 million in liquidity from decentralized exchange pools. No client or customer data was compromised during the breach.

Bedrock confirmed the September 27 exploit publicly. The protocol offers multi-asset liquid restaking through UniBTC, UniETH, and UnilOTX products. These synthetic token representations enable yield generation through staking mechanisms.

Despite the attack, Bedrock demonstrated remarkable recovery. The protocol’s total value locked grew from $240 million in September 2024 to $535 million by June 2025, according to DefiLlama data.

The incident reflects broader trends in cryptocurrency security threats. Hackers increasingly target social engineering over technical vulnerabilities. CertiK reported over $2.1 billion stolen in crypto-related attacks during 2025.

Phishing attacks and wallet compromises account for most losses. CertiK co-founder Ronghui Gu noted the strategic shift toward social engineering methods. This evolution challenges traditional security approaches across the blockchain industry.

The Fuzzland case highlights critical insider threat risks facing security companies. Internal access controls require enhanced scrutiny and monitoring systems.
