OoPS virus Removal Guide

What is OoPS ransomware virus?

OoPS crypto-virus locks your files in a ZIP archive with an elaborate password

The image of OoPS ransomware virus

OoPS functions as a file-encrypting threat which employs AES[1] algorithm to corrupt 45 different file types. It aims at MS Office, image, audio, video, and other popular files. The virus adds these files to a password-protected ZIP archive and appends .ramen file extension. Recently, another version of the malware has been detected OopsLocker virus.

Undoubtedly, people standing behind this cyber threat offer to get back access to encrypted data by paying the ransom. How much money they ask to pay is currently unknown. However, taking this risky deal is not recommended because you might end up with money loss too. Thus, after the attack, we highly recommend focusing on OoPS removal.

It’s important to delete all malicious components from the system to protect your device from further damage or cyber attacks. The best way to do it is running a full system scan with FortectIntego pr Malwarebytes.

The virus arrives on the system as obfuscated “OoPS Ramenware.exe” file. Once it’s executed, malware makes modifications on system and instals various malicious components in %AppData%, %Roaming%, %Local%, %LocalLow% and %Temp% directories. Malware might also modify Windows Registry and affected several sub-keys in order to run as soon as a computer is turned on.

Before starting data encryption, OoPS ransomware might also get administrative privileges of the device. What is more, it might delete Shadow Volume Copies of the targeted files and backups. Thus, data recovery is nearly impossible without specific decryption software.

We want to remind that purchasing it from cyber criminals is not recommended. They might not have working decryption software, you might be tricked into installing malicious software, or they might simply disappear as soon as they receive the ransom. We believe it’s better to remove OoPS and lose your files than risking to lose the money as well.

Another version – OopsLocker – strikes

On July 18th, a new version has been detected roaming around. The malware which introduces itself as OopsLocker threat. As the previous version, it targets Windows OS users via RDP and spam emails. Its trojan, Deepscan.Generic.Ransom.Wcryg!c, may also lurk for victims in corrupted domains. After the infiltration, the infection encodes files and marks them with .oops file extension.

Luckily, at the moment the activity of the malware is quite low. The malware seems to be rather a test version. Its GUI is not highly sophisticated. It warns users several times not to make any modifications to the files. In exchange to the data, the felons require paying 0.1 bitcoins to the indicated Bitcoin address. In case of technical issues, they provide only4you@protonmail.com address.

Furthermore, the malware also drops the following files: \oops\,oops.exe
EncryptedFiles.txt, EncryptedKey, and KeyHash. Once you notice one of them make a rush to reboot the system. Since the malware is still undeveloped, you may disrupt its processes. Then, proceed to OopsLocker removal. Malware elimination tools will help you detect and delete all associated files. Let us remind you once again not to pay the ransom.

The virus lurks for unsuspecting users in spam attachments

OoPS ransomware is mostly distributed via malicious spam email campaigns.[2] Criminals use social engineering techniques and pretend to be from well-known companies, such as PayPal, FedEx, Amazon, etc. Also, they might claim to be representatives from banks and governmental organizations. Thus, crooks can easily trick victims into opening an obfuscated attachments or click on an infected link.

Once a person does that, the malicious payload is dropped and executed on the system. Besides, OoPS might also enter the system as fake updates or software. Usually, they are promoted as crucial components or useful programs in unknown file-sharing sites, P2P networks or torrents. In order to avoid this cyber threat, you always have to think twice before opening suspicious email attachment and choose reliable sources for software downloads and updates.

Before clicking on content provided in an unknown email, look up for grammar and spelling mistakes, strange phrases, lack of credentials, and similar details that might reveal criminals. In order to protect your computer from OoPS ransomware, you should also choose reliable sources for software downloads and updates.

How to prevent from getting ransomware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
