Overview
In a recent wave of cyber threats, MetaMask users have become prime targets for sophisticated phishing email scams. These attacks leverage the credibility of MetaMask, a popular cryptocurrency wallet and browser extension, to deceive unsuspecting users into revealing their sensitive account information. The latest iteration of this scam has been observed through the compromise of a major router manufacturer’s support portal, where phishing emails were auto-sent to individuals seeking assistance. This method not only exploits the trust users place in legitimate support channels but also highlights the evolving tactics of cybercriminals in their quest to exploit the burgeoning cryptocurrency sector.
The
phishing emails in question mimic official MetaMask communications, often incorporating familiar branding and language to enhance their credibility. They typically urge recipients to urgently update their MetaMask accounts, claiming that failure to do so could result in loss of access or other critical issues. The email includes a link that appears to direct users to the MetaMask website but actually leads to a malicious site designed to harvest login credentials and other personal information. This approach capitalizes on the user’s fear of losing access to their cryptocurrency assets, driving them to act quickly without due caution.

How they operate
The scam typically begins with the delivery of a phishing email that masquerades as a legitimate notification from MetaMask. The email, designed to look official, informs recipients of an urgent need to update their MetaMask account due to a supposed security enhancement or system update. The message includes a convincing call to action, urging users to click on a link to perform this update. However, this link does not direct users to the genuine MetaMask site but instead leads them to a fraudulent webpage.
The deceptive URL structure used in these scams often employs the “userinfo” part of the URL schema to mislead users. For example, a URL might appear to be from a legitimate domain like “metamask.io” but actually direct users to a different site. This is achieved by embedding a misleading authority component before the actual domain, such as “hxxps://metamask.io
@zpr[.]io/x4hFSxCxEqcd.” In this format, the portion before the “@” symbol is intended to make the URL look trustworthy, while the true destination is a phishing site designed to capture login credentials.
Once users are lured to the fake MetaMask site, the phishing page is crafted to closely resemble the legitimate MetaMask interface. It prompts users to enter their MetaMask credentials, including their private keys or recovery phrases, under the pretense of completing the required update. In reality, the phishing site captures these inputs and sends them to the attacker’s server.
The stolen credentials are then used by the attackers to gain unauthorized access to users’ MetaMask wallets. Since MetaMask is a non-custodial wallet, the stolen private keys grant attackers full control over the user’s funds. The compromised data may be used for various malicious activities, including unauthorized transactions and theft of cryptocurrency assets.
Technical defenses against such phishing attacks include user education, recognizing suspicious URL structures, and implementing advanced email filtering systems. Additionally, cryptocurrency users are advised to manually verify the authenticity of any security notifications and avoid clicking on unsolicited links in emails. By understanding the mechanics of these scams and maintaining vigilance, users can better protect themselves against this prevalent and sophisticated form of cybercrime.
