Malicious extensions for the Chrome browser continue to spring up just as quickly as the search giant cuts them down. This month, another batch appeared.
Google deleted 49 malicious Chrome extensions from the Chrome Web Store in mid-April after security researcher Harry Denley found them phishing cryptocurrency users. The extensions impersonate Chrome extensions for legitimate cryptocurrency wallets, but when installed they pilfer the users’ private keys and other secrets used to access digital wallets so that their authors can steal victims’ funds. Now Denley has found more.
Talking to Naked Security, Denley explained that he finds new ones each day. He pointed us to this Pastebin entry showing the original 49 he reported in April, along with another 22. The new ones impersonated the Ledger, KeepKey, MetaMask, and Jaxx wallets. The IDs on the left are extension IDs, which show up at the end of an extension’s URL when viewed in the Chrome store.
