bridge[.]arbtirum[.]guru

This domain, bridge.arbitrum.guru, is flagged for elevated-risk Arbitrum bridge phishing, a targeted attack vector designed to mimic legitimate cross-chain token bridges. Analysis indicates the domain was engineered to deceive users into connecting wallets or entering private keys under the pretense of facilitating Ethereum Layer 2 transactions, specifically impersonating Arbitrum’s official bridge interface. The threat type is classified as cryptocurrency phishing with infrastructure tailored to exploit trust in decentralized finance (DeFi) protocols. Infrastructure analysis reveals multiple high-confidence indicators of malicious activity. The domain resolves to IP address 172.67.163.248, a host associated with prior phishing campaigns. VirusTotal reports 3 out of 95 security vendors flagging the domain as malicious, a detection ratio consistent with early-stage phishing operations. Gridinsoft assigns a trust score of 0/100, reflecting zero legitimacy. The domain appears on one security blocklist and is currently offline, though this status may change. Historical records indicate the domain was likely registered recently, aligning with the rapid deployment tactics typical of phishing infrastructure. Mitigation requires immediate action from both users and network defenders. Users who interacted with bridge.arbitrum.guru should revoke any connected wallet permissions, rotate private keys, and monitor accounts for unauthorized transactions. Network-level protections should include DNS filtering to block resolution of the domain and its associated IP, as well as real-time monitoring for related indicators such as SSL certificates or subdomains. Given the domain’s offline status, defenders should prioritize hunting for residual artifacts, including cached pages or phishing kits deployed on compromised hosts. Organizations operating Arbitrum-based services should proactively warn users about this specific threat vector and implement multi-factor authentication (MFA) for bridge transactions to reduce reliance on single points of failure.
