Online data monitoring and prevention service Under the Breach says a hacker is attempting to sell client information belonging to cryptocurrency hardware wallet manufacturers Trezor, KeepKey, and Ledger. 

According to a tweet published May 24, Under the Breach said an the alleged hacker of the Ethereum.org forum was attempting to sell databases belonging to Trezor, KeepKey and Ledger. The stolen data was reportedly obtained via an exploit involving the e-commerce platform Shopify, with the tweet implying more leaks could have occurred that have gone unnoticed. 

The hacker also claimed to have the full SQL database belonging to the online crypto and fintech investment bank, BnkToTheFuture. 

In a subsequent tweet, the data monitoring service claims to have warned BnkToTheFuture about the leaked information.

The documents posted by Under the Breach reveal the hacker allegedly has information belonging to three large databases encompassing 80,000 clients.  

Ledger responded to the proposed Shopify data breach the same day, calling the hack a “rumor.” The crypto wallet manufacturer claimed to have analyzed screenshots from the leaked database and found it did not match their records. 

A Shopify representative told News.Bitcoin that the company had investigated the security breach and found “no evidence” of any compromise.
