What is Trojan.NSIS.Injector (A) virus?

Trojan.NSIS.Injector (A) is ransomware-type malware. It looks for the files on your disk drive, encrypts it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your documents inaccessible, this malware additionally does a lot of damage to your system. It alters the networking settings in order to stop you from checking out the elimination guides or downloading the anti-malware program. Sometimes, Trojan.NSIS.Injector (A) can additionally block the setup of anti-malware programs.

Trojan.NSIS.Injector (A) Summary

Summarizingly, Trojan.NSIS.Injector (A) ransomware activities in the infected PC are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Creates RWX memory;
  • Dynamic (imported) function loading detected;
  • Reads data out of its own binary image;
  • CAPE extracted potentially suspicious content;
  • Authenticode signature is invalid;
  • Created a process from a suspicious location;
  • Installs itself for autorun at Windows startup;
  • Creates a copy of itself;

  • Blocking the launching of .exe files of anti-malware programs
  • Blocking the launching of installation files of security tools

Ransomware has been a headache for the last 4 years. It is difficult to realize a more hazardous malware for both individual users and companies. The algorithms used in Trojan.NSIS.Injector (A) (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need a lot more time than our galaxy currently exists, and possibly will exist. But that virus does not do all these horrible things instantly – it can require up to several hours to cipher all of your files. Thus, seeing the Trojan.NSIS.Injector (A) detection is a clear signal that you must begin the elimination procedure.

Where did I get the Trojan.NSIS.Injector (A)?

Typical tactics of Trojan.NSIS.Injector (A) spreading are basic for all other ransomware variants. Those are one-day landing web pages where users are offered to download the free program, so-called bait e-mails and hacktools. Bait emails are a relatively new strategy in malware spreading – you receive the e-mail that mimics some routine notifications about shipments or bank service conditions changes. Inside of the e-mail, there is a corrupted MS Office file, or a link which leads to the exploit landing page.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Avoiding it looks pretty easy, but still needs tons of awareness. Malware can hide in different places, and it is far better to prevent it even before it gets into your system than to depend on an anti-malware program. Common cybersecurity knowledge is just an important item in the modern world, even if your interaction with a PC remains on YouTube videos. That may save you a great deal of time and money which you would spend while searching for a fix guide.
