Scare tactics used by ransomware

Ransomware is a type of malware that locks away access to files on a particular computer or network and releases them upon making payments. Recent variants of ransomware do so by encrypting data that makes them impossible to recover without a decryption key. However, many variants of ransomware go beyond just encrypting files just to force payments. Here are some scare tactics used by recent ransomware variants. Keep in mind, however, that making payments does not guarantee the release of a victim’s files.

Jigsaw, a ransomware variant that appeared in 2016, featured the image of the antagonist in the “Saw” movie, as well as a countdown timer. While several variants use intimidating images to persuade victims, many ransomware variants have adopted the use of a countdown timer to pressure victims into paying the ransom.

Other variants went even further and made payments grow exponentially as time progressed, giving victims an illusion of an incentive if they pay now rather than later. There are also those that stretch this payment period for weeks, giving the victim ample time to make the payment.

Some ransomware variants also lie about their capabilities to pressure its victims. Although there are variants that can steal data, there are those who simply say so and threaten victims that their data would be released on the internet if they fail to pay. Some even use the logo of local law enforcement and accuse victims of federal crimes just so they would pay immediately.
