Stupid ransomware virus – another threat to your personal files

Stupid ransomware is a file-encrypting virus that is written in .NET programming language. Malware has few different versions which are recognized by the appended file extensions. The ransomware can add .haters, .xncrypt or .FailedAccess extensions to each of the targeted files. It uses a strong encryption algorithm that locks the files and prevents users from opening or using them. In order to get back access to the data, victims need to obtain a specific decryption key. However, purchasing it from the cyber criminals is not recommended. The virus is designed to corrupt 61 file types, including various image, audio, video and text files, that are stored in My Pictures, My Music, Downloads and other C:\\Windows and C:\\Programs top-level directories. Thus, there’s no doubt that victims lose the most valuable files. If you have data backups, you should not worry about lost documents or photographies. You just need to focus on the Stupid removal and once it’s done, plug in external storage and copy necessary data to the computer.

The image of Stupid ransomware

Cyber criminals always give victims instructions how to redeem encrypted files. It’s unknown how much money authors of the Stupid ransomware asks to pay; however, you should not consider this option. If you are thinking about paying the ransom, let us tell few possible scenarios that should discourage you from reaching for your credit card. Hackers are not obliged to recover your files. Ransomware is their illegal source of income, and they are interested in getting money. Keeping their promise to recover your data is a matter of their conscience. Thus, they may not provide a decryptor.[1] If you decide to pay the demanded sum of money, you can always be asked to transfer more Bitcoins. Otherwise, crooks might threaten to delete your files or cause other damage to the device. What is more, you might purchase not working or infected decryptor, and suffer from other malicious programs. Thus, you should forget your damaged files for a while and remove Stupid ransomware using Reimage or another malware removal program.

Ransomware prevention tips

Developers of Stupid ransomware might use several strategies to spread malware and infiltrate devices. However, if you take precautions, you should not encounter ransomware. File-encrypting viruses can enter the system when you open a malicious email attachment, click on a malware-laden ad, install bogus software or fake update, etc. Thus, you should stay away from spam emails. It’s better not to open them at all, but if you did that, please do not click on any buttons, links or attached files. Bear in mind that these emails might look like sent from banks, governmental institutions, and other well-known companies, so you should always double-check information about the sender and be critical. Stupid ransomware might also use exploit kits and take advantage of outdated software or other vulnerabilities to hijack the device. Thus, you should keep all your software updated and do not install any programs or updates from unknown or shady sources. We want to remind that ads informing about detected viruses or offering to install software are dangerous! Lastly, you should be prepared for the worst and regularly update data backups.[2] They are crucial in case of the attack.
