A cybersecurity firm has issued warnings over a new phishing campaign targeting users of the popular crypto wallet MetaMask.
In a Thursday post written by Halborn’s technical education specialist Luis Lubeck, the active phishing campaign used emails to target MetaMask users and trick them into giving out their passphrase.
The firm analyzed scam emails it received in late July to warn users of the new scam. Halborn noted that at an initial glance, the email looks authentic with a MetaMask header and logo and with messages that tell users to comply with Know Your Customer (KYC) regulations and how to verify their wallets.
However, Halborn also noted there are several red flags within the message. Spelling errors and a fake sender’s email address were two of the most obvious. Furthermore, a fake domain called metamaks.auction was used to send the phishing emails.
Phishing attacks are social engineering attacks using targeted emails to lure victims into revealing more personal data or clicking links to malicious websites that attempt to steal crypto.
There was also no personalization in the message, the firm noted, which is another warning sign. Hovering over the call to action button reveals the malicious link to a fake website which prompts users to enter their seed phrases before redirecting to MetaMask to empty their crypto wallets.
Halborn, which raised $90 million in a Series A round in July, was founded in 2019 by ethical hackers offering blockchain and cybersecurity services.
In June, Halborn researchers discovered a case where a user’s private keys could be found unencrypted on a disk in a compromised computer. MetaMask patched its extension versions 10.11.3 and later following the discovery.
However, there was no mention of the new email phishing threat on MetaMask’s Twitter feed at the time of writing.
Last week, Celsius users were warned of a phishing threat following the leak of customer emails by a third-party vendor employee.
In late July, security researchers warned of a new malware strain called Luca Stealer appearing in the wild. The information stealer has been written in the Rust programming language and targets Web3 infrastructure such as crypto wallets. Similar Malware called Mars Stealer was discovered targeting MetaMask wallets in February.
