Glupteba Trojan – Distribution Information and What Actions To Take To Prevent It From Compromising A Network?

The Glupteba Trojan malware could spread through a few methods, the most effective of which is explained in the following paragraphs.

How the process works in chronological order – the authors send Bitcoin transactions via a designated Electrum Bitcoin wallet, which was threatened by a prolific phishing campaign in the past. Glupteba, programmed with a hardcoded ScriptHash string, then makes its way via a public list of Electrum servers to find every transaction made by the cybercriminals.

Inside said transactions lies the OP_RETURN command data which contains an encrypted Command and Control domain. The ScriptHash string is set to decrypt the data once it has been received. This acts as a re-pinging to the host, with each new Bitcoin transaction making a new C&C connection.

The process is also showcased in the below infographic made by TrendMicro:
