According to the FBI\u2019s 2024 Internet Crime Report<\/a>, crypto-related scams accounted for nearly $16.6 billion in victim losses last year across the globe ($9.3 billion in the United States alone \u2014 a 66% increase from 2023). Crypto thieves employ a variety of tactics to defraud people, but a certain type, known as a crypto wallet drainer<\/i>, is proliferating and one of the ways scammers find new victims is through malicious browser extensions.<\/p>\n

A crypto wallet drainer is basically any type of fraudulent method that gives bad actors unauthorized access to a user\u2019s crypto wallet. In the case of browser extensions, we find malicious extensions masquerading as legitimate extensions from trusted, known crypto wallets. Unfortunately for users who install a scam crypto wallet extension and input their private keys and credentials, the effects are often immediate and devastating. The funds quickly vanish and they\u2019re virtually impossible to recover.<\/p>\n

According to Add-ons Operations Manager Andreas Wagner, who leads content security and review efforts, AMO (addons.mozilla.org<\/a>) has uncovered \u201chundreds\u201d of scam crypto wallets over the past few years. \u201cIt\u2019s a constant cat and mouse game,\u201d Wagner explains, as “developers try to work around our detection methods.\u201d<\/p>\n

To help protect Firefox users, the Add-ons Operations team developed an early detection system designed to identify and stop crypto scam extensions before they find traction with unsuspecting users. The first layer of defense involves automated indicators that determine a risk profile for wallet extensions submitted to AMO. If a wallet extension reaches a certain risk threshold, human reviewers are alerted to take a deeper look. If found to be malicious, the scam extensions are blocked immediately.<\/p>\n

While add-on reviewers are doing everything they can to find and snuff out crypto wallet scams before they can do harm, there are things users should be aware of as well to help protect themselves. \u201cCheck your crypto wallet\u2019s website to see if they have an official extension, and only use the one they link to,\u201d advises Wagner, while adding you might also consider reaching out directly to your crypto wallet service to confirm you\u2019re selecting a legitimate extension. You can never be overly cautious when it comes to protecting your digital assets. There are too many disastrous tales out there<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
