Recently we have seen an emerging trend among malware distributors - Bitcoin miners being integrated into installers of game repacks.
This type of system hijacking is just one of the many ways to exploit a user by utilizing their system's computing resources to earn more cash. Malware is easily bundled with game installers that are then uploaded and shared with unsuspecting users using torrent download sites. Once a machine is infected, a downloaded Bitcoin miner silently carries out mining operations without the user's consent.
We have seen this technique used by Trojan:Win32/Maener.A. This threat is dropped by TrojanDropper:Win32/Maener.A as a bundle with some games.
