A malicious Firefox browser extension was removed after the add-on, called Safety Wallet, deceived and defrauded users by emptying their Cryptocurrency wallets.
Cali, a Mozilla add-ons user, explained that a few hours after installing and logging in with his real Safepal credentials, he saw his wallet drop to $0.
He continued: “I was deep in shock… I saw my last transactions and saw that [$4,000 of my funds] were transferred to another wallet. I could not believe it [was an] add-on that is deployed in the add-on list of Mozilla Firefox.”
A spokesman for Mozilla told Bleeping Computer: “When we become aware of add-ons that pose a risk to security and privacy according to our Add-On policies, we take steps to prevent them from running in Firefox. In this instance, shortly after we became aware of potential abuse by this extension, we took action to block and remove it from the Firefox Add-on store. Users should be especially cautious about installing software that might have access to private information or financial resources.”
