Trojan-Downloader.Win32.Rakhni

Trojan-Downloader.Win32.Rakhni is a Trojan downloader that may install a member of the Rakhni family of file-locker Trojans or a 'miner' program that uses your hardware for generating cryptocurrency. Malware experts also caution that this threat can compromise other PCs over any non-secure, local network connections. Durable network security settings and appropriate anti-malware software can keep it from spreading and delete Trojan-Downloader.Win32.Rakhni before it drops any other threats.

Threat Actors Keeping Their Infection Options Open

The profits from different versions of the Rakhni family of file-locking Trojans, such as 2016-era members like the Zeta Ransomware, the 'Guardware@india.com' Ransomware, or the Green_Ray Ransomware, may be waning. New infection attempts are using a flexible Trojan downloader, the Trojan-Downloader.Win32.Rakhni, which may drop other threats instead of a file-locking Trojan, depending on the state of the system. This Trojan also appears built for avoiding threat analysis-dedicated systems and can self-terminate in virtual environments or whenever it detects associated security software.

If the compromised PC includes a dedicated Bitcoin directory, Trojan-Downloader.Win32.Rakhni downloads and installs a traditional member of the Rakhni's family. These Trojans use encryption for locking documents and other media, inject new extensions into their names, and create text-based ransoming messages asking for Bitcoin ransoms for the decryption solution. However, malware experts are confirming that this is only one of two possibilities in a Trojan-Downloader.Win32.Rakhni infection.

If it doesn't find the Bitcoin folder, Trojan-Downloader.Win32.Rakhni installs a cryptocurrency-mining program, such as MinerGate, which it may use for generating either Dashcoin or Monero in a hidden, background process. The new Trojan may or may not hijack the GPU for this purpose.

No matter which payload it selects, Trojan-Downloader.Win32.Rakhni also disables the Windows Defender software through a series of Command Prompt instructions.

Managing the Trojan that's of Two Minds about Attacking Your PC

Between Trojans capable of causing overheating damage to the hardware and ones that block you from opening your digital media, Trojan-Downloader.Win32.Rakhni's payload has long-term implications on both the health of the PC and that of its contents. However, malware researchers also are emphasizing this Trojan downloader's network-based distribution function, which places it in the sub-category of a Trojan-worm hybrid formally. Trojan-Downloader.Win32.Rakhni copies itself into the Startup folder of each Windows PC that it can access over a non-secure local network, which places multiple servers at risk of having their data held for ransom.

Trojan-Downloader.Win32.Rakhni uses some self-enciphering techniques for hiding its identity from threat analysis software, along with closing in protected environments automatically. Malware researchers also are noting a tendency of its components for using fake file details, including Microsoft and Adobe-themed names or signatures. Most modern anti-malware products should identify and remove Trojan-Downloader.Win32.Rakhni in spite of these features accurately.

Having one's hardware taken over for creating money may seem better than not having your files open, but the long-term consequences to a compromised system are no less harmful. Keep Trojan-Downloader.Win32.Rakhni from having options with how to attack your computer by not falling for the tactics, such as fake advertisements and e-mail attachments, that are most likely of installing it.
