Blockaid Flags $182K Exploit On ShapeShift FOX Colony
An attacker drained roughly $132,700 from ShapeShift's FOX Colony on Arbitrum on May 13, 2026, with a follow-on hit adding about $50,000 for total losses near $182,700. Security firm Blockaid flagged the exploit and named the attacker wallet at 0xeed236Afb6967f74099a0a6bf078BC6b865fbf28. The flaw sits in Colony Network's contract design, so any colony exposing the same function pattern is exposed too, on any chain.
The Exploit
The attacker targeted the executeMetaTransaction function in FOX Colony's contracts. They meta-signed a transaction that repointed the colony's resolver to a malicious contract, then used a delegate call to drain funds. Because the affected registration function carries no permission modifier, any external address can call it. That's the part that turns one exploit into a class of exploits: the lock isn't broken on a single door, the lock is missing from every door of that design.
The FOX token contracts themselves are not the target. Security checks on the FOX token across Ethereum, Arbitrum, Polygon, Gnosis, and Optimism show open source, non-pausable, no blacklist, ownership locked. The damage is to the governance program built on Colony Network, not to FOX as a token.
Why This Is A Class Vulnerability
Blockaid's warning explicitly extends beyond ShapeShift. Every Colony Network deployment that exposes executeMetaTransaction on top of EtherRouter shares the same attack surface, regardless of chain. That makes this a pattern alert, not a single-project incident. Other colonies haven't necessarily been drained yet. They can be.
This lands in a bad year for DeFi security. April 2026 was the worst month on record for DeFi exploits, with roughly $625 million drained across 28 incidents. Blockaid has flagged a $5 million Wasabi Protocol drain and a $6.7 million TrustedVolumes exploit in recent weeks alone. The FOX Colony loss is small by comparison, which is exactly why it's worth attention: the technique matters more than the dollar figure.
What To Watch For
- Other Colony Network deployments: If you participate in any colony that uses the EtherRouter pattern, treat your funds as exposed until the colony confirms a patch or migration.
- ShapeShift's response: No public statement at the time the alert went out. Watch for an official post, a contract pause, or a migration plan before treating FOX Colony participation as resumed.
- The attacker wallet:
0xeed236Afb6967f74099a0a6bf078BC6b865fbf28. Movements from this address or repeated patterns at the same function signature on other colonies are the live signal. - Token approvals to colony contracts: Approvals you granted for staking, voting, or other Colony interactions persist independently of the exploit. Review and revoke what you don't need.
- Recovery scams: Named exploits attract fake support accounts within hours. ShapeShift, Colony, and Blockaid will not DM you a rescue link.
