Ransom.Agent.NR detection is a malware detection you can spectate in your computer. It generally shows up after the provoking activities on your PC – opening the dubious e-mail, clicking the advertisement in the Internet or setting up the program from suspicious sources. From the second it appears, you have a short time to take action before it starts its harmful activity. And be sure – it is much better not to await these harmful actions.

What is Ransom.Agent.NR virus?

Ransom.Agent.NR is ransomware-type malware. It looks for the files on your disk drive, encrypts it, and then asks you to pay the ransom for getting the decryption key. Besides making your files locked, this malware additionally does a ton of harm to your system. It alters the networking settings in order to stop you from reading the elimination tutorials or downloading the antivirus. In some cases, Ransom.Agent.NR can even prevent the launching of anti-malware programs.

Ransom.Agent.NR Summary

Summarizingly, Ransom.Agent.NR ransomware actions in the infected computer are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Attempts to connect to a dead IP:Port (2 unique times);
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Creates RWX memory;
  • Dynamic (imported) function loading detected;
  • Enumerates running processes;
  • CAPE extracted potentially suspicious content;
  • Drops a binary and executes it;
  • The binary contains an unknown PE section name indicative of packing;
  • Authenticode signature is invalid;
  • Detects Sandboxie through the presence of a library;
  • Behavioural detection: Injection (Process Hollowing);
  • Executed a process and injected code into it, probably while unpacking;
  • Behavioural detection: Injection (inter-process);
  • Creates or sets a registry key to a long series of bytes, possibly to store a binary or malware config;
  • Created a process from a suspicious location;
  • Installs itself for autorun at Windows startup;
  • Creates a hidden or system file;
  • CAPE detected the Andromeda malware family;
  • Checks the presence of disk drives in the registry, possibly for anti-virtualization;
  • Attempts to modify proxy settings;
  • Creates a copy of itself;
  • Attempts to modify Explorer settings to prevent hidden files from being displayed;
  • Ciphering the files kept on the target’s disks — so the victim cannot open these documents;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-malware programs

Ransomware has actually been a major problem for the last 4 years. It is hard to realize a more harmful virus for both individual users and companies. The algorithms used in Ransom.Agent.NR (typically, 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. However, that malware does not do all these terrible things immediately – it may take up to a few hours to cipher all of your documents. Hence, seeing the Ransom.Agent.NR detection is a clear signal that you should start the elimination process.

Where did I get the Ransom.Agent.NR?

Standard methods of Ransom.Agent.NR distribution are usual for all other ransomware examples. Those are one-day landing websites where victims are offered to download and install the free app, so-called bait e-mails and hacktools. Bait e-mails are a relatively new strategy in malware distribution – you receive the e-mail that mimics some regular notifications about deliveries or bank service conditions shifts. Within the email, there is a corrupted MS Office file, or a web link which opens the exploit landing page.

Malicious email spam

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

Avoiding it looks quite simple, but still requires a lot of attention. Malware can hide in different places, and it is much better to stop it even before it invades your computer than to rely on an anti-malware program. Simple cybersecurity knowledge is just an important thing in the modern-day world, even if your interaction with a PC remains on YouTube videos. That may save you a great deal of money and time which you would certainly spend while trying to find a solution.
