The Adylkuzz Crypto-Miner is a Trojan that uses the infected PC's hardware for generating cryptocurrency via background processes. Since these attacks don't provide symptoms or a user interface for the user of the compromised machine, passive anti-malware protection and safe Web usage habits are your best defenses against this Trojan. Use specialized anti-malware utilities for identifying or uninstalling the Adylkuzz Crypto-Miner, which will attempt to conceal its components or means of entry from any casual observation.

Your Choice of Consequences for Security Failure: Hardware Damage or Locked Files

While the campaigns for file-encrypting threats like the WannaCryptor Ransomware and the '.wcry File Extension' Ransomware are seeing increased attention, thanks to news of associated NSA exploits, other threat actors also are making different uses out of the same security loopholes. Recently, malware experts managed to verify another kind of Trojan abusing the backdoor loopholes of both DoublePulsar and EternalBlue for compromising new systems. Besides copying the WannaCrypto Ransomware's infection strategy, this other threat, the Adylkuzz Crypto-Miner, also takes steps to isolate the PC from any future infections from competing sources.

The Adylkuzz Crypto-Miner's campaign appears to be global in scale and is targeting a variety of network-vulnerable systems to distribute itself to as many servers as possible per individual security breach. Simultaneously, the Adylkuzz Crypto-Miner also shuts down SMB (or Server Message Block) networking communications, which may interfere with file-sharing, networked printing tasks and other activities. The threat actors most likely do this to keep other threats from gaining access to the infected servers, including additional, redundant versions of the Adylkuzz Crypto-Miner. The Trojan, then, mines the isolated systems for a cryptocurrency.

Like the Kirk Ransomware or the NsCpuCNMiner, the Adylkuzz Crypto-Miner generates an alternative cryptocurrency, Monero, instead of the traditional Bitcoin. In the meantime, its intensive resource usage for creating this digital currency can cause performance problems or even hardware failure.

Keeping Your Hardware Off Limits from Trojan Excavation

The Adylkuzz Crypto-Miner belongs to a classification of threats that don't display symptoms or user interfaces of any type, besides the performance problems they might provoke. As previously noted, its delivery mechanism, the DoublePulsar vulnerability, also is a viable threat for installing other types of threatening software. Initial infections may be thanks to such proliferation strategies as forged e-mail attachments or brute-force attacks, the latter of which depend on bad password management to break into a network.

Other than limiting network traffic, the Adylkuzz Crypto-Miner doesn't attack the victim's PC directly. However, extended cryptocurrency miner infections may use your graphics card, CPU and other components without any safety measures in place to prevent burnout. If you feel that your network or personal computer may be under attack by a threat of this type, allow your anti-malware products to analyze the environment, including all active memory processes, and remove the Adylkuzz Crypto-Miner safely.

Many of the infection vectors related to the Adylkuzz Crypto-Miner can be prevented from loading, as long as you're using updated software. A March-dated security update by Microsoft corrects one of the most egregious of these network vulnerabilities and is an easy way to make sure your servers will not fall prey to the latest in hardware-mining technology.
