Security firm discovers $500M vulnerability in Tron multisig accounts

After reporting the vulnerability to Tron in February, the researchers highlighted that the issue was promptly addressed and resolved within a few days.

A research team at dWallet Labs has discovered a zero-day vulnerability in Tron multisig accounts, allowing an attacker to bypass the multisignature mechanism and sign transactions with a single signature.

In a technical breakdown post, the research team said the vulnerability could have impacted $500 million in assets held in Tron multisig accounts. This is because it allows any signer to “completely overcome the multisig security offered by TRON.”

As its name suggests, multisignature wallets require multiple signers defined in an account to approve transactions and move funds, allowing the creation of joint accounts in crypto. Each account signer holds their own keys and the account requires a certain threshold for approving transactions. 

According to the research team, the vulnerability with Tron’s multisig allows for generating many valid signatures. They wrote:

“We can bypass the multisig verification process by signing the same message with non-deterministic nonces of our choice. By doing so, we will be able to generate many valid different signatures for the same message by the same private key.”

According to the cybersecurity team, Tron ensures the signatures are unique instead of checking if the signers are unique. Because of this, signers can potentially “double vote” or sign twice. Omer Sadika, the CEO of dWallet Labs, said the fix was simple: verify the address instead of the number of signatures.
