Abandoned Defi website used to host Crypto Wallet Drainers

Decentralized Finance (DEFI) users were warned yesterday by a new fraud vector. The scammer took over the abandoned project’s website and led the previous users to sign a malicious “drainage” transaction.

This warning comes from 0xngmi, the founder of the pseudonym for the Analytics platform Defillama. Defillama confirmed that the expired domain has been removed from the platform and its browser extensions, but it still urged users to be warned.

This passive tactic differs from more common fraud methods, usually requiring active participation from the scammers themselves. When taking over a legitimate URL, the scam relies on former users who have returned to interact with familiar websites (which are likely to be bookmarked if they follow best practices) to remove any funds they have had Previously deposited when the project was still active.

There is no team left to warn security violations or replace malicious interfaces, so there is little to do about these proper defy website traps besides careful checking of transactions being signed.

What is a front-end attack?

In contrast to closed-source centralized cryptographic exchange, the defi protocol runs directly on blockchains such as Ethereum and Solana.

The majority of users interact with the Defi protocol via the project’s website or through a user-friendly interface that creates transactions that are signed through the Crypto wallet. Technically, it is possible to create transactions using other tools, including block explorers like Etherscan, but this is unusual.

Naturally, the frontend itself is an attack vector for becoming a hacker. The general approach that led to the waves of events last summer was Compromising on official websites through social engineering of DNS providers.

Sites are usually cloned, but transactions presented to users are modified to grant, for example, approval for the token or send funds directly to the attacker.

Simpler tactics include similar cloning of legal sites, but host them via similar URLs or obfuscations, or “spoofing,” like X or Google hyperlinks.

Of course, some front-end losses are not fraud. Rather, it is a code vulnerability in the site that hackers can exploit. This is a fact about the $2.6 million Defi Lending Platform Morpho on Friday, and fortunately, it was on the forefront by the well-known Mev Bot C0ffeebabe.eth.

Such attacks that generally target individual users are unlike any other threats facing users of the Defi platform, such as exploiting the smart contract itself or major personal compromises. These often lead to greater losses when assets hosted within a project’s contract are emitted at once.

Just this week, both of these types of incidents have resulted in significant losses. Just yesterday, Zksync announced that the $5 million ZK token left from the project’s airdrop had been looted after the 1-of-1 multisig appears to have compromised.

Monday, distributed PERPS exchange Kiloex lost $7.5 million Project price due to Oracle vulnerabilities.

Another risk comes from the team itself, which frequently manages the vast amount of project tokens. As we’ve seen in the past few days, teams can withdraw liquidity on a whim or sell token OTCs. This results in wild price fluctuations when overrated token leverage positions explode or get hacked by yourself.
