Remove MassJacker Malware

MassJacker is a cryptojacking malware designed to hijack cryptocurrency transactions. It achieves this by intercepting and replacing copied cryptocurrency wallet addresses with attacker-controlled ones, a tactic known as clipboard hijacking. As a result, victims unknowingly send funds to cybercriminals instead of their intended recipients. Since cryptocurrency transactions are irreversible, recovering stolen funds is nearly impossible.

What is MassJacker Malware?

MassJacker is believed to be operated by multiple threat actors, suggesting that it may function as Malware-as-a-Service (MaaS). It employs advanced techniques to evade detection, including obfuscation, runtime function manipulation, code scrambling, and payload encryption. This makes it particularly dangerous and difficult to remove.
