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.
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.
Automated removal of JSE file virus
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.
Ways of non-ransom recovery of .jse files
Cracking the crypto used by this ransom trojan is more of a science fiction thing rather than an attainable prospect for the masses. This is why the troubleshooting in predicaments of this sort is a matter of two approaches: one is to pay the ransom, which isn’t an option for many victims; and the other is to apply instruments that take advantage of the ransomware’s possible weaknesses. If the latter is your pick, the advice below is a must-try.
Backups can make your day
Not only are you a lucky person in case you’ve been backing up your most important files, but you’re also a wise and prudent user. This isn’t necessarily a resource-heavy activity these days – in fact, some providers of online services are allocating a sufficient size of cloud storage space for free so that every customer can easily upload their critical data without paying a penny. Having removed JSE ransomware, therefore, all you have to do is download your stuff from the remote server or transfer it all from an external piece of hardware if that’s the case.
Restore previous versions of encrypted files
A positive upshot of using this technique depends on whether or not the ransomware has erased the Volume Shadow Copies of the files on your PC. This is a Windows feature that automatically makes and keeps the backups of data elements on the hard drive as long as System Restore is enabled. The cryptoware in question is programmed to switch off the Volume Shadow Copy Service (VSS), but it has reportedly failed to in some cases. Checking one’s options regarding this workaround is doable in two ways: through the Properties menu of each file or by means of the remarkable open-source tool called Shadow Explorer. We recommend the software-based way because it’s automated, hence faster and easier. Just install the app and use its intuitive controls to get previous versions of the encrypted objects reinstated.
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 Data Recovery Pro by ParetoLogic features this type of capability therefore it can be applied in ransom attack scenarios to at least get the most important files back. So download and install the program, run a scan and let it do its job.
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.
