A Twitter user and software architect, named as WizardofAus, warns crypto community about malware contaminated Google Chrome extension called Ledger Secure.
In a tweet posted on January 2, WizardofAus said that this is not a Ledger product asked users to remove it if they have installed it. WizardofAus’ tweet reads:
“Malware Chrome extension alert
If you have “Ledger Secure” installed – REMOVE IT.
The @ChromeExtension “Ledger Secure” contains malware that passes your seed phrase back to the extension’s author.
This is *not* a @Ledgerproduct.
Successfully used against @hackedzec”
The affected user mentioned in the tweet, hackedzec lost 600 ZEC, valued at approximately $16 K at the time of tweet, in his Ledger Nano by the Chrome extension’s creator. WizardofAus told in his next tweet.
WizardofAus also mentioned the Casa founder Jeremy Welch’s warnings last year against browser extension malware at the Bitcoin (BTC) event Baltic HoneyBadger in Riga.
In his next tweet, he outlined the risks posed by these products, and asked users to be diligent. He said:
“Firstly, be very careful what extensions you install. If you’re using the same computer for your crypto as you use generally, be extra diligent.
Better to have a separate minimal machine – or use a Virtual Machine that is the only place you do crypto activity.”
WizardofAus further said:
“For using software with your hardware wallets, use the wallet vendor’s software.
When you get that software, check it comes from the vendor’s website, that the link is secure, and ideally you can validate the software checksum.
Please learn from others’ expensive lessons”
Hackedzec Twitter account was notably created in January 2020. The anatomy of the account shows that he created the account specifically to spread awareness following his experience of the malware.
The Twitter handle of Ledger Support also confirmed the detection of malware extension saying that this not a legitimate Ledger product.
