Trojan:Win32/Corebot detection is a virus detection you can spectate in your computer. It often appears after the preliminary activities on your PC – opening the untrustworthy email, clicking the banner in the Internet or mounting the program from untrustworthy sources. From the second it appears, you have a short time to act before it begins its destructive activity. And be sure – it is much better not to wait for these malicious effects.

What is Trojan:Win32/Corebot virus?

Trojan:Win32/Corebot is ransomware-type malware. It searches for the files on your disks, ciphers it, and then asks you to pay the ransom for receiving the decryption key. Besides making your files locked, this virus additionally does a lot of damage to your system. It changes the networking settings in order to avoid you from looking for the elimination tutorials or downloading the anti-malware program. Sometimes, Trojan:Win32/Corebot can even prevent the launching of anti-malware programs.

Trojan:Win32/Corebot Summary

In summary, Trojan:Win32/Corebot virus activities in the infected computer are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Creates RWX memory;
  • Possible date expiration check, exits too soon after checking local time;
  • Dynamic (imported) function loading detected;
  • CAPE extracted potentially suspicious content;
  • Drops a binary and executes it;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Attempts to remove evidence of file being downloaded from the Internet;
  • Behavioural detection: Injection (Process Hollowing);
  • Executed a process and injected code into it, probably while unpacking;
  • Behavioural detection: Injection (inter-process);
  • Performs a large number of encryption calls using the same key possibly indicative of ransomware file encryption behavior;
  • Creates a copy of itself;
  • Encrypting the documents kept on the victim’s drive — so the victim cannot open these documents;
  • Blocking the launching of .exe files of anti-virus apps
  • Blocking the launching of installation files of anti-virus programs

Ransomware has been a horror story for the last 4 years. It is challenging to imagine a more dangerous virus for both individuals and organizations. The algorithms used in Trojan:Win32/Corebot (typically, 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 actually exists, and possibly will exist. But that virus does not do all these terrible things immediately – it can take up to a few hours to cipher all of your files. Hence, seeing the Trojan:Win32/Corebot detection is a clear signal that you need to start the removal procedure.

Where did I get the Trojan:Win32/Corebot?

Ordinary methods of Trojan:Win32/Corebot distribution are usual for all other ransomware variants. Those are one-day landing sites where victims are offered to download the free software, so-called bait emails and hacktools. Bait e-mails are a quite new method in malware spreading – you receive the email that mimics some standard notifications about deliveries or bank service conditions shifts. Inside of the email, there is a malicious 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.

Preventing it looks pretty uncomplicated, however, still needs tons of focus. Malware can hide in different spots, and it is far better to stop it even before it goes into your system than to rely on an anti-malware program. Standard cybersecurity knowledge is just an essential thing in the modern-day world, even if your relationship with a computer stays on YouTube videos. That can save you a great deal of time and money which you would spend while looking for a solution.
