What is known about Necurs rootkit?
Win32/Necurs, Trojan:Win32/Necurs or just simply Necurs virus is a dangerous trojan horse, which is used to distribute various computer infections, for example, rogue anti-spyware that belong to 'WinWeSec' family. What is more, this virus can be used to deliver destructive payloads of various malicious viruses. Once it infiltrates target computer system, it adds its own registry entries, connects to a remote Command & Control server, then disables antivirus protection programs and starts the malicious activity on the system. Recently, malware researchers have discovered that computers infected with Necurs are united into a dangerous botnet and that it is used to distribute most dangerous malware, including ransomware viruses. Locky, ODIN or Shit ransomware are only a few infamous virus names that are being delivered via Necurs botnet. It has also been used to spread Dridex banking Trojan and numerous other illegal programs that are meant to cause havoc on the target computer system.
Although Necurs botnet has been destroyed by law enforcement agencies in 2015, it has been resurrected and became fully operational again. Officially, it is the largest botnet in the world (featuring over 6.1 million bot devices). If the computer becomes infected with the rootkit and becomes a Necurs spambot, attackers can use this machine however they want - they can install additional malware on it, use the computer to send out massive spam email campaigns, or use it to distribute malicious programs to other computers, or perform DDoS attacks. It has been discovered that Locky virus is actively being distributed with the help of this botnet because during its shutdown malware researchers have noticed a drop in the spam emails that delivered Locky virus.
Win32/Necurs malware can remain silent in the system for weeks until it receives a command from the remote host. Unlike unprofessional computer viruses, this one stays quiet and does not display a single warning message, and discloses its presence only when it needs to. It is very hard to remove Necurs rootkit from the system, and we definitely do not recommend you to do that manually. Reimage is a reliable Necurs removal tool that can eliminate the malware for good.
