In the previous piece of Ransomware 101, we talked about locker ransomware. Here, we will talk about the other type of cryptovirological activity that is more complex and deadly as compared to locker strain. The purpose of “Ransomware 101” series is to increase awareness regarding cryptovirology and ransomware removal and protection.
Crypto Ransomware
Crypto ransomware is also known as Data Locker for an obvious reason i.e. it locks down the stored data on the infiltrated device. Unlike locker ransomware, this cryptovirological strain doesn’t limit its destructions to few features of the operating system. They are designed to encrypt different file formats stored at different locations in the device.
Data: A Priced Commodity of Today
With the extensive digitization of our lifestyles, data has become a valuable commodity just like vehicles, cash, and any other tangible item. Developers of crypto ransomware have understood the importance of data more lucidly than users. Therefore, they have devised a malware program that holds data hostage. The aim is to receive extortion money from the affected victims to ‘release their data’.
Crypto Ransomware Shows its Presence After Staying Under the Radar
Once it infiltrates into a digital environment, a crypto ransomware quietly starts to look for the file extensions that are susceptible for its encryption. After sorting its target, the strain starts its encryption activity and finally releases a ransom note through an autorun window or a text file.
Extensive Ransomware Removal Measures are Needed
We have discussed how the devices infected by locker strains can be disinfected by minimal ransomware removal measure. However, it is quite opposite in the case of crypto ransomware. Security experts have to analyze the complete encryption module of the strain to develop a decryption key that can conduct effective ransomware removal action. Reverse engineering is often used by digital security personnel to develop a ransomware decrypter.
Affected Device Remain Operational
Unlike locker strain, the affected device remains operational even after the encryption because it doesn’t affect the critical features of the operating system. However, experts advise against the use of infected devices before the conclusion of ransomware removal activities.
