Victim of multi-chain exploit targeting at least 6 wallets across Ethereum, Arbitrum, and Solana between October 19–21, 2026 seeking other affected users.
Security & Exploits ·
Between October 19 and 21, 2026, an attacker drained at least 6 wallets across Ethereum, Arbitrum, and Solana in what appears to be a coordinated multi-chain exploit. One affected user has begun reaching out to other victims through an onchain message posted on Arbitrum, stating they are filing a police report in France and seeking to contact others who experienced losses from the same address.
The victim is using the blockchain explorer to coordinate with affected parties, explicitly noting they will not request money, private keys, or ask recipients to click links. The message was posted as an onchain communication accessible to anyone who engaged with or monitored the attacker's address during the incident window.
The scope and mechanics of the exploit remain unclear—it is not yet known whether the drains involved a single smart contract vulnerability, compromised private keys, a shared dependency across multiple applications, or another vector. The victim's involvement of French law enforcement suggests a formal investigation may be underway, but no official statements or additional details about recovery efforts or asset recovery prospects have been made public.
