We know that regular ATMs are a popular target for cybercriminals. But so far, there has been much less discussion about Bitcoin ATM malware, probably because there are relatively few machines available worldwide. With the growing popularity of cryptocurrencies and the fact that cybercriminals will always try to take advantage of them to make money, mining malware has been common over the past year. So it's not surprising that we're thinking that bitcoin ATM malware is going to appear in the underground market. Unlike regular ATMs, Bitcoin ATMs do not have uniform verification or security standards. For example, Bitcoin ATMs do not need to use ATMs, credit or debit cards for transactions, but instead use mobile numbers and ID cards for user authentication. The user must then enter the wallet address or scan their QR code. Wallets used to store digital currency are not standardized and can be downloaded from the app store, so cybercriminals are sure to have an advantage. While searching through underground forums, we found a user offering Bitcoin ATM malware for sale.

Electrum is a popular software wallet that works by connecting to a dedicated server. These servers receive a hash of the Bitcoin address in the wallet and reply with transaction information.
