A new Trojan horse has been detected to spread at an alarming rate that surpasses even the WannaCry infection. The malware, called Zusy has been detected to replicate via a worm and then drop what appears to be a cryptocurrency miner, known as Tiggre (other name is Digmein), which aims to overload the CPU and GPU of the affected computers in order to obtain tokens at their expense and credit them to the cyber-crooks behind this outbreak. In case your computer has been infected by the Zeus Trojan, we recommend that you read this article as it will help you remove this malware and restore your PC’s performance to normal.

See If Your System Has Been Affected by Zusy Trojan
In order to be widespread on a serious level, the Zusy Virus uses a worm infection, which has been reported at VirusTotal and uploaded on Twitter by researcher Vess (@VessOnSecurity ).

The Zusy malware may use advanced exploits since researchers have reported it in VT as being highly evasive. One report by PayloadSecurity indicateds the following replication URLs in relation to the Zusy virus:
In addition to this, the malware may also have the capability of hijacking flash drives and other external memory carriers that copy scripts that allow for the infection to take place by exploiting AutoPlay in Windows.
Zusy Trojan – Analysis
The Zusy Trojan is the type of threat which aims to drop it’s payloaad files. The payload fils have random names and are also located in folders with random names. The folders are created in the %AppData% directory:
→ %AppData%\{random}\{random file}.exe – also detected as TSPY_ZBOT.ZUSY
%AppData%\{random}\{random file 2}.{random extension}
%AppData%\{random}\{random file 3}.tmp
Once this is done, the Zusy virus then creates an autostart type of registry entry in the following registry sub-key:
The entry is set to run the randomly named .exe file, we mentioned above. Besides these modifications, the Trojan also adds registry entries in the following Windows sub-keys:
→ HKEY_CURRENT_USER\Software\Microsoft\
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\SharedAccess\Parameters\ FirewallPolicy\StandardProfile\AuthorizedApplications\
List %Windows%\explorer.exe = “%Windows%\explorer.exe:*:Enabled:Windows Explorer”
From there it may download a CryptoCurrency miner virus, known as the Tiggre miner (W32/Tiggre), which aslo drops malicious files in the %AppData% directory and begins connecting to a remote server in order to begin mining for cryptocurrencies by utilizing your CPU and GPU to almost a 100%, which results in your PC starting to slow down at an alarming rate.
In addition to this, since it’s also a spyware, the Zusy Trojan may also use it’s tracking technologies to steal different type of information from your PC, based on how the virus is configured. The types of data can be the following:
Log your keystrokes.
Steal saved passwords.
Obtain files from your PC.
Take over your communication logs (Chat history, etc.).
Take screenshots.
Control your web camera.
Furthermore, the Zusy virus may also delete its main malicious file after infecting your computer and continue to spread on another PC’s on a network level of replication (via intermediary and end devices, like routers, switches, etc.). This is done for malware researchers to prevent discovering the infection and hence creating a kill switch of it.
