Win32/Injector.COFG detection is a malware detection you can spectate in your system. It frequently shows up after the provoking actions on your computer – opening the dubious e-mail, clicking the advertisement in the Web or installing the program from suspicious resources. From the second it shows up, you have a short time to act until it begins its malicious action. And be sure – it is much better not to await these harmful actions.

What is Win32/Injector.COFG virus?

Win32/Injector.COFG is ransomware-type malware. It searches for the files on your computer, ciphers it, and after that asks you to pay the ransom for getting the decryption key. Besides making your documents locked, this virus additionally does a lot of damage to your system. It modifies the networking settings in order to stop you from checking out the removal manuals or downloading the antivirus. Sometimes, Win32/Injector.COFG can also stop the setup of anti-malware programs.

Win32/Injector.COFG Summary

In summary, Win32/Injector.COFG malware actions in the infected PC are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Uses Windows utilities for basic functionality;
  • Reads data out of its own binary image;
  • CAPE extracted potentially suspicious content;
  • Drops a binary and executes it;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Behavioural detection: Injection (Process Hollowing);
  • Behavioural detection: Injection (inter-process);
  • Deletes executed files from disk;
  • Anomalous binary characteristics;
  • Uses suspicious command line tools or Windows utilities;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Ciphering the documents located on the target’s disk drive — so the victim cannot use these files;
  • Blocking the launching of .exe files of anti-virus apps
  • Blocking the launching of installation files of anti-malware apps

Ransomware has actually been a major problem for the last 4 years. It is challenging to picture a more damaging virus for both individuals and companies. The algorithms utilized in Win32/Injector.COFG (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have a lot more time than our galaxy currently exists, and possibly will exist. However, that malware does not do all these bad things without delay – it may require up to several hours to cipher all of your files. Therefore, seeing the Win32/Injector.COFG detection is a clear signal that you have to start the clearing process.

Where did I get the Win32/Injector.COFG?

Typical tactics of Win32/Injector.COFG spreading are standard for all other ransomware variants. Those are one-day landing websites where users are offered to download the free app, so-called bait emails and hacktools. Bait e-mails are a relatively new tactic in malware spreading – you receive the email that mimics some regular notifications about shipments or bank service conditions updates. Within the e-mail, there is an infected MS Office file, or a link which leads to the exploit landing site.

Malicious email spam

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

Avoiding it looks quite simple, however, still requires tons of attention. Malware can hide in different spots, and it is far better to prevent it even before it invades your PC than to depend on an anti-malware program. Common cybersecurity awareness is just an important item in the modern world, even if your relationship with a PC remains on YouTube videos. That may save you a lot of time and money which you would certainly spend while trying to find a fixing guide.
