Ransomware deployment has turned into a profitable business, where some computer criminals write the code and others distribute the malady at their own risk. The money at stake is huge – the estimates for 2015 alone reach hundreds of millions of dollars. Such an amount of maliciously earned resources, obviously, allows the fraudsters to improve their infrastructure and come up with more advanced samples. Ransom32, for instance, is a trojan that may appear to be a replica of its numerous counterparts, but it turns out unique in several ways. First off, it features a robust tracking mechanism reflected in an intuitive administration panel. Effectively, this is affiliate marketing in its generally accepted form, where virtually anyone interested can sign up, start spreading the threat and get a share of each ransom payment sent by victims.
As soon as the virus is executed and its files have been unpacked, it connects to the malign C&C server in order to retrieve the BTC address for ransom payment and obtain the encryption key. It encrypts all of the victim’s personal files while ignoring system data inside such directories as ‘windows’, ‘temp’, etc. Then the trojan triggers a warning message providing information on the ransom payment deadline and other recovery details. The cryptographic algorithm used for locking the user’s documents and media is AES, with a separate 128-bit key getting generated for each file. This key also undergoes encryption, but with RSA. Ultimately, the complex encoding routine is impossible to bypass. There’s no reason to lose heart, however, as there exist techniques to restore the information seized by Ransom32 that don’t presuppose paying.
Automated removal of Ransom32/NW.js ransomware
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 Ransom32 encrypted data
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 Ransom32, 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.
