simplocker-ransomwareA new Ransomware infection, carrying the name ‘SimpleLocker’ is been detected by security software out in the wild. The attack may affect both Android devices as well as PCs. This type of trojan horse infection is employed with the purpose of scanning the victim device for necessary and important files and encrypt them. After that, it may leave a ransom note prompting the user to pay in exchange for the decryption keys. ‘SimpleLocker’ may change the files extension to an unfamiliar one(ex: .aaa, .crypt, etc). This type of ransomware uses a strong algorithm to encrypt user files that are very difficult to decrypt. The ransom payment for decryption of the files encrypted by ‘SimpleLocker’ is usually done by using anonymous TOR – based networking and involves BitCoins for maximum identity concealment.

How Did I Become Infected?

There are several ways you could have become a victim of this devious threat. One of them is by opening a spam mail with an attached document or a picture in it that might have contained malicious code within its own. More so, you may have clicked on an ad or could have been redirected to a drive-by download type of web page. Such pages may initiate a download, containing ‘SimpleLocker’ concealed as a Java applet, Flash Player or an ActiveX update. Some web pages may directly inject exploit creating code within the user device. Experts advise on being aware what you install on your device. This is because PUPs (Potentially Unwanted Programs) usually administer most pop-ups and redirects that may be bundled with other free programs you may have downloaded online.

More About ‘SimpleLocker’ Ransomware

One variant of the ‘SimpleLocker’ Ransomware is believed to display the following message on either your smartphone, tablet or other devices:

“Attention! Your phone has been blocked! The device has been blocked for the distribution of child pornography, zoophilia, and other sick things. To unlock your phone, you need to pay 900 hryvnias.
1.Find a payment fulfillment terminal, located in your proximity.
2.In it, locate Money.
4. Input 260 hryvnias and tap on ‘Pay’
Do not forget to take your receipt! After the payment has been conducted your device will be unencrypted in 24 hours. IN CASE, YOU HAVEN’T PAYED YOU WILL LOSE ALL THE DATA ON YOUR DEVICE FOREVER!”

The principle of ‘SimpleLocker’ ransomware is the same for both Android devices and PCs – It scans and encrypts data. What is interesting is that this particular ransomware is reported by researchers to encrypt whole memory cards in phones, asking for ransom. Also, it is believed to lock out the screen of the device with the ransom note, without giving any possibility to the user in accessing his information. Users may simply reboot their smartphones, but this may not help at all since it activates once more. It is even worse for users who have all of their contacts saved on their phone since this particular attack may also encrypt the contact entries and cause a lot of headaches.

For PCs, the situation varies but usually it involves making an anonymous payment by downloading TOR browser, which uses virtual private networking and several other technologies to mask identities. Some variants of this ransomware may try to convince users that they are dealing with a government institution and have committed a crime while browsing. FBI and other law enforcement agencies are one of the most preferred ones when it comes to these type of attacks. They are designed to use the fear in inexperienced users from the law hence convince them to conduct a payment.
