Ransom.StopCrypt detection is a malware detection you can spectate in your system. It usually appears after the preliminary procedures on your PC – opening the suspicious e-mail messages, clicking the banner in the Internet or setting up the program from suspicious sources. From the second it shows up, you have a short time to take action before it begins its destructive action. And be sure – it is better not to await these harmful effects.

What is Ransom.StopCrypt virus?

Ransom.StopCrypt is ransomware-type malware. It looks for the files on your disks, encrypts it, and then asks you to pay the ransom for receiving the decryption key. Besides making your files locked, this virus also does a lot of harm to your system. It changes the networking setups in order to avoid you from checking out the removal guides or downloading the antivirus. In some cases, Ransom.StopCrypt can even stop the setup of anti-malware programs.

Ransom.StopCrypt Summary

In summary, Ransom.StopCrypt virus actions in the infected computer are next:

  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Behavioural detection: Executable code extraction – unpacking;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Creates RWX memory;
  • Dynamic (imported) function loading detected;
  • Enumerates the modules from a process (may be used to locate base addresses in process injection);
  • CAPE extracted potentially suspicious content;
  • Unconventionial language used in binary resources: Uzbek (Latin);
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • CAPE detected the RedLine malware family;
  • Encrypting the documents located on the victim’s disk — so the victim cannot open these files;
  • Blocking the launching of .exe files of anti-malware programs
  • Blocking the launching of installation files of anti-virus apps

Ransomware has been a headache for the last 4 years. It is challenging to realize a more harmful virus for both individual users and businesses. The algorithms used in Ransom.StopCrypt (typically, 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 terrible things without delay – it can take up to a few hours to cipher all of your documents. Hence, seeing the Ransom.StopCrypt detection is a clear signal that you must start the removal process.

Where did I get the Ransom.StopCrypt?

Usual tactics of Ransom.StopCrypt injection are common for all other ransomware examples. Those are one-day landing web pages where victims are offered to download and install the free program, so-called bait e-mails and hacktools. Bait emails are a quite new strategy in malware spreading – you receive the e-mail that mimics some standard notifications about shipments or bank service conditions updates. Within the e-mail, there is a malicious MS Office file, or a web 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 pretty simple, but still requires a lot of recognition. Malware can hide in different places, and it is better to prevent it even before it goes into your computer than to depend on an anti-malware program. Basic cybersecurity awareness is just an important thing in the modern world, even if your relationship with a computer remains on YouTube videos. That may keep you a lot of money and time which you would certainly spend while looking for a fix guide.
