What is BScope.TrojanDownloader.Smoke virus?

BScope.TrojanDownloader.Smoke is ransomware-type malware. It searches for the documents on your disk drives, ciphers it, and after that asks you to pay the ransom for getting the decryption key. Besides making your files inaccessible, this malware also does a ton of harm to your system. It modifies the networking settings in order to prevent you from checking out the elimination manuals or downloading the antivirus. Sometimes, BScope.TrojanDownloader.Smoke can even block the launching of anti-malware programs.

BScope.TrojanDownloader.Smoke Summary

In summary, BScope.TrojanDownloader.Smoke virus actions in the infected PC are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • CAPE extracted potentially suspicious content;
  • Unconventionial language used in binary resources: Korean;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Checks the presence of disk drives in the registry, possibly for anti-virtualization;
  • Encrypting the documents located on the target’s drive — so the victim cannot check these documents;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-virus apps

Ransomware has been a headache for the last 4 years. It is difficult to imagine a more hazardous virus for both individuals and organizations. The algorithms used in BScope.TrojanDownloader.Smoke (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have more time than our galaxy already exists, and possibly will exist. But that malware does not do all these horrible things without delay – it can take up to several hours to cipher all of your files. Hence, seeing the BScope.TrojanDownloader.Smoke detection is a clear signal that you need to start the elimination procedure.

Where did I get the BScope.TrojanDownloader.Smoke?

Standard tactics of BScope.TrojanDownloader.Smoke spreading are basic for all other ransomware examples. Those are one-day landing web pages where users are offered to download the free app, so-called bait e-mails and hacktools. Bait e-mails are a relatively new method in malware distribution – you get the email that simulates some normal notifications about deliveries or bank service conditions changes. Inside of the e-mail, there is an infected MS Office file, or a 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 demands tons of attention. Malware can hide in different places, and it is much better to stop it even before it invades your PC than to rely upon an anti-malware program. General cybersecurity awareness is just an essential item in the modern-day world, even if your relationship with a PC remains on YouTube videos. That can save you a great deal of money and time which you would certainly spend while trying to find a fixing guide.
