Trojan.Buzus detection is a virus detection you can spectate in your system. It usually appears after the provoking actions on your PC – opening the suspicious e-mail, clicking the advertisement in the Internet or mounting the program from dubious resources. From the moment it shows up, you have a short time to do something about it before it starts its harmful action. And be sure – it is much better not to await these malicious effects.

What is Trojan.Buzus virus?

Trojan.Buzus is ransomware-type malware. It looks for the documents on your disk drives, encrypts it, and after that asks you to pay the ransom for getting the decryption key. Besides making your files locked, this virus also does a lot of damage to your system. It modifies the networking settings in order to avoid you from reading the removal tutorials or downloading the antivirus. In some cases, Trojan.Buzus can additionally stop the launching of anti-malware programs.

Trojan.Buzus Summary

In total, Trojan.Buzus virus activities in the infected system are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • HTTPS urls from behavior.;
  • CAPE extracted potentially suspicious content;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Behavioural detection: Injection (Process Hollowing);
  • Behavioural detection: Injection (inter-process);
  • Behavioural detection: Transacted Hollowing;
  • CAPE detected the STOP malware family;
  • Attempts to modify proxy settings;

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

Ransomware has been a headache for the last 4 years. It is hard to imagine a more dangerous malware for both individual users and organizations. The algorithms used in Trojan.Buzus (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need more time than our galaxy currently exists, and possibly will exist. But that malware does not do all these horrible things without delay – it may take up to several hours to cipher all of your files. Thus, seeing the Trojan.Buzus detection is a clear signal that you should start the removal process.

Where did I get the Trojan.Buzus?

Usual methods of Trojan.Buzus distribution are common for all other ransomware variants. Those are one-day landing sites where users are offered to download and install the free software, so-called bait emails and hacktools. Bait e-mails are a pretty new strategy in malware spreading – you get the e-mail that mimics some regular notifications about deliveries or bank service conditions modifications. Inside of the email, there is a corrupted MS Office file, or a link which opens the exploit landing site.

Malicious email spam

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

Avoiding it looks quite simple, but still demands tons of focus. Malware can hide in different places, and it is much better to prevent it even before it goes into your system than to rely upon an anti-malware program. Simple cybersecurity awareness is just an essential item in the modern-day world, even if your relationship with a PC stays on YouTube videos. That can save you a lot of time and money which you would spend while trying to find a solution.
