JSE file virus decryption and removal

The issue with an unsanctioned change of file format to .jse isn’t trivial, because it most likely means that a ransomware program has entered the computer.

The crypto malware alert du jour has to do with a bevy of user reports about the scrambling of data files on PCs that involves the JSE extension. Whereas it’s premature to accurately affiliate this threat with the existing ransomware families, the undoubted fact is it’s a new campaign aimed at defrauding people of money. The JSE file virus appears to be circulating through several vectors at this point. One is social engineering. The entry point in this case is human gullibility for the most part. The virus operators are leveraging a botnet to produce a large volume of spam. The rogue incoming webmail messages go with attachments, usually ZIP files, which launch the malicious process once extracted through double-clicking on the victim’s end. The other distribution technique occasionally detected by experts involves exploit kits, where Windows computers are compromised via unpatched software vulnerabilities.

JSE isn’t actually a harmful entity per se. It denotes the ‘JScript Encoded’ file format, a subtype of JavaScript that, ideally, can be processed using a commonplace text editor. The malicious implication, however, isn’t nearly as serene. When the ransomware plague in question attacks a computer and appends the .jse extension to the user’s sensitive files, things get out of hand because the data becomes inaccessible. The offending application takes the personal data lookup task seriously, scanning the entire hard disk for the most popular forms of information. What makes matters worse is that the infection also traverses plugged-in devices and network shares for objects that are likely to be important for the user.

As soon as the database of valuable files is readily available, the JSE ransomware unleashes the crypto part of its hideous feature set. Using a fusion of AES and RSA cryptosystems, it makes sure that the victim’s access to the data is completely blocked. The warped files are easy to tell – they all have the .jse string at the end. The only avenue to undo the damage is the use of the private RSA key, which unfortunately doesn’t reside on the machine. The malware spawns multiple ransom notes on the PC, which explain what happened and advise the person on recovery. In particular, the user is told to submit somewhere around 1 Bitcoin to obtain the unique master key and decrypt the information. Instead of quenching the extortionists’ thirst for easy profit, though, it’s strongly recommended to try a few workarounds first.

JSE ransomware automated removal and data recovery

Owing to an up-to-date database of malware signatures and intelligent behavioral detection, the recommended software can quickly locate the infection, eradicate it and remediate all harmful changes. So go ahead and do the following:

1. Download and install the antimalware tool. Open the solution and have it check your PC for PUPs and other types of malicious software by clicking the Start Computer Scan button

2. Rest assured the scan report will list all items that may harm your operating system. Select the detected entries and click Fix Threats to get the troubleshooting completed.

Data recovery toolkit to the rescue

Some strains of ransomware are known to delete the original files after the encryption routine has been completed. As hostile as this activity appears, it can play into your hands. There are applications designed to revive the information that was obliterated because of malfunctioning hardware or due to accidental removal. The tool called Stellar Data Recovery features this type of a capability and therefore it can be applied in ransom attack scenarios to at least get the most important files back. So use the app to get an idea of what data can be restored and let it do the recovery job. Here is a step-by-step walkthrough:

1. Download and install Stellar Data Recovery.

2. Open the application, select the types of recoverable files to look for, and click Next.

3. Choose the areas you want the tool to recover from and click the Scan button.

4. Having scanned the specified locations, the program will display a notification about the total amount of recoverable data. Close the dialog and click the Recover button. This will hopefully help you get some of your valuable files back.

Ransomware Prevention Tips

To avoid JSE ransomware and other file-encrypting infections in the future, follow several simple recommendations:

These techniques are certainly not a cure-all, but they will add an extra layer of ransomware protection to your security setup.

Revise your security status

Post-factum assessment of the accuracy component in malware removal scenarios is a great habit that prevents the comeback of harmful code or replication of its unattended fractions. Make sure you are good to go by running an additional safety checkup. Another benefit of using the antimalware tool is that it will keep ransomware threats from intruding on your computer further on.
