TrojanRansom.HiddenTear detection is a virus detection you can spectate in your computer. It often shows up after the preliminary activities on your PC – opening the untrustworthy email, clicking the banner in the Web or setting up the program from unreliable sources. From the moment it appears, you have a short time to do something about it until it starts its malicious activity. And be sure – it is much better not to wait for these malicious effects.

What is TrojanRansom.HiddenTear virus?

TrojanRansom.HiddenTear is ransomware-type malware. It searches for the files on your computer, encrypts it, and then 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 alters the networking setups in order to stop you from checking out the elimination articles or downloading the anti-malware program. In some cases, TrojanRansom.HiddenTear can also prevent the launching of anti-malware programs.

TrojanRansom.HiddenTear Summary

Summarizingly, TrojanRansom.HiddenTear malware activities in the infected system are next:

  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Dynamic (imported) function loading detected;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Possible date expiration check, exits too soon after checking local time;
  • Enumerates the modules from a process (may be used to locate base addresses in process injection);
  • CAPE extracted potentially suspicious content;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • CAPE detected the RedLine malware family;
  • Anomalous binary characteristics;
  • Encrypting the documents located on the target’s disks — so the victim cannot check these files;
  • Blocking the launching of .exe files of anti-virus apps
  • Blocking the launching of installation files of security tools

Ransomware has actually been a headache for the last 4 years. It is hard to imagine a more damaging virus for both individuals and corporations. The algorithms used in TrojanRansom.HiddenTear (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 actually exists, and possibly will exist. However, that virus does not do all these terrible things immediately – it may require up to a few hours to cipher all of your documents. Hence, seeing the TrojanRansom.HiddenTear detection is a clear signal that you should begin the elimination procedure.

Where did I get the TrojanRansom.HiddenTear?

Typical ways of TrojanRansom.HiddenTear spreading are standard for all other ransomware examples. Those are one-day landing web pages where victims are offered to download and install the free software, so-called bait e-mails and hacktools. Bait e-mails are a relatively modern strategy in malware distribution – you get the e-mail that mimics some regular notifications about deliveries or bank service conditions changes. 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 quite easy, however, still requires a lot of awareness. Malware can hide in different spots, and it is far better to prevent it even before it gets into your system than to trust in an anti-malware program. General cybersecurity knowledge is just an essential item in the modern-day world, even if your interaction with a PC remains on YouTube videos. That may save you a lot of time and money which you would spend while searching for a fix guide.
