Details of a previous Electrum wallet hack surfaced following the massive 1,400 Bitcoin (BTC) theft that hit headlines a few days ago. 

"I had a similar situation 2 months ago," a Github user named Cryptbtcaly posted on the social media platform on Aug. 31. The user claimed someone pilfered 36.5 BTC from one of their wallet addresses. The BTC reportedly ended up spread across five different addresses. 

"Some of the stolen Bitcoin went to Binance, but they ignore my appeals and do not return," cryptbtcaly added.

Details of a larger hack surfaced on Aug. 30, when a different Githubber reported 1,400 BTC as missing from their Electrum wallet. Prior to the hack, the victim reportedly had not used this particular Electrum wallet in about three years. 

The thief, or thieves, appear to have also utilized a Binance account, back in January 2018, making a 5 BTC withdrawal, according to on-chain analysis using data from Crystal Blockchain. The transaction ID, or TXID, for the 1,400 BTC theft involved more than 75 addresses, based on comments from a Binance representative. One of those addresses was the one that withdrew 5 BTC in January 2018. 

A phishing attack also plagued Electrum users in December 2018, although it is unclear at this time if the incident relates to the present day hacks.
