Fake Hardhat npm Packages Target Ethereum Developers

A new malicious campaign is currently targeting Ethereum developers in the wild. The campaign is using fake Hardhat npm packages to steal private keys. It is crucial for developers to implement proper monitoring and security measures to safeguard their development environments from such threats.

New Malicious Campaign Uses Fake Hardhat npm Packages To Steal Private Keys

In a recent report by the Socket.dev Research Team, it has been revealed that a fresh malicious campaign is actively going after Ethereum developers.

This particular campaign is essentially a supply chain attack directed at the Nomic Foundation and Hardhat platforms. It involves the distribution of fake Hardhat npm packages to Ethereum developers.

The threat actors responsible for this campaign are creating malicious packages that closely resemble legitimate Hardhat plugins to deceive users. These fake packages claim to provide the same functionalities as the genuine plugins. They also mimic the deployment processes of legitimate plugins, such as gas optimization and smart contract testing, to appear more authentic to users.

Since these packages are hosted on npm, they appear trustworthy to developers, making it easier for them to extract data as they mimic similar functionalities. This allows the packages to steal sensitive information like private keys and mnemonics from the Hardhat environment. The stolen data is then encrypted using an AES key and sent to endpoints controlled by the attackers.

The attackers could also utilize these packages to deploy malicious contracts, potentially disrupting the Ethereum mainnet.

The Socket.dev team has provided detailed information about this malicious campaign in their report. During their investigation, they identified 20 malicious packages created by three authors. One of these packages, @nomicsfoundation/sdk-test, has received over 1000 downloads, indicating the significant impact of this campaign.

To mitigate the risks posed by this and similar threats, the researchers recommend that users, especially Ethereum developers, should enforce stringent security monitoring and auditing practices in their development environments. Additionally, developers should exercise caution when selecting packages to avoid falling victim to malicious ones.
