Vulnerability in Ledger Library Affects Numerous DApps

Vulnerability in Ledger Library Affects Numerous DApps

A vulnerability has been discovered in a library developed by Ledger, potentially affecting numerous decentralized applications (DApps) that integrate with it.

Vulnerability in Ledger Library Could Impact Numerous DApps

The DeFi community on X (formerly Twitter) is abuzz with reports of a security flaw in the Connect-Kit toolset developed by Ledger. This toolset has been compromised with malware capable of automatically draining user assets upon any interaction.

Several popular DApps, including Hey, SushiSwap, and Zapper, which utilize this toolset, may have their front-ends compromised, potentially affecting users. Even the token revocation site, Revoke, is among the impacted websites.

Confirmation from SushiSwap

The CTO of SushiSwap has confirmed that their front-end was affected by this attack. He identified the root cause as a compromised web3 connector, which allowed the attacker to inject malicious code affecting multiple DApps. The malicious code appears to have originated from the GitHub repository of Ledger's hardware wallet.

He further stated:

"Any DApps using LedgerHQ/connect-kit are vulnerable to this attack...This isn't a single attack but a large-scale attack on multiple DApps. The Ledger DApps connection kit allows developers to connect their DApps with Ledger hardware wallets using the Ledger Extension or Ledger Live."

He also urged users to "avoid interacting with any DApps until further notice."

Recent Development and Safety Measures

The vulnerability seems to have emerged recently (around 4:44 PM on 12/14). Users who have not interacted with DApps in the past 4-5 hours are likely safe.

Technical KOLs recommend that users refrain from any transactions in the near future to minimize the risk of asset theft. They specifically advise against connecting to any DApps using Ledger cold wallets.

Update from Ledger

Ledger's X account acknowledged the vulnerability and stated that a patch is being deployed. However, users are still advised not to interact with any DApps at this time. Ledger hardware wallets remain secure and are not affected by this library vulnerability.

ZachXBT shared the attacker's wallet address, estimating that $610,000 had been stolen via this exploit. Tether has since frozen the funds associated with the hacker.

The latest patch version is 1.1.8. Users should ensure they have updated to this version before engaging in any new interactions with Ledger.

Stay tuned for further updates on this developing situation.
