1. Online criminals are using our sense of shame to rob us.
According to the F-Secure Labs:
Ransomware’ is a type of malware that attempts to extort money from a computer user by infecting and taking control of the victim’s machine, or the files or documents stored on it. Typically, the ransomware will either ‘lock’ the computer to prevent normal usage, or encrypt the documents and files on it to prevent access to the saved data.
The ransom demand will then be displayed, usually either via a text file or as a webpage in the web browser. This type of malware leverages the victim’s surprise, embarrassment and/or fear to push them into paying the ransom demanded.
Ransomware may arrive as part of another malware’s payload, or may be delivered by an exploit kit such as Blackhole, which exploits vulnerabilities on the affected computer to silently install and execute the malware.
2. It can infect you regardless where you live whether you’re on your PC or mobile device.
The internet erases geography. If you often install applications from third-party Android markets and happen to download a Trojan:Android/SLocker app, then you can get infected. If you stay within the official markets then this risk is minimized.
3. Prevention is better than the cure.
Make sure you have updated security protection for all your PCs and devices. Practice good computing habits on your PC and your mobile.
Be very cautious when installing any application on your device. Although official markets have served up malware, the risk is minimized heavily. Always keep your phone’s OS and apps up-to-date.
Once a malware is able to encrypt your data, there’s usually very little chance to decrypt them yourself so regularly backup important files with either offline or online/cloud solutions.
4. Once your files are encypted, you probably won’t get them back.
For instance Trojan:Android/SLocker uses AES for encryption, which is a really strong encryption. You can try to use our removal tool but remember number 3.
5. Don’t pay.
Giving into the scheme only encourages the bad guys.
