There is a growing threat that is causing many victims to be infected by ransomware.
Cybercriminals are attacking innocent users with a wide range of malware and then demanding money from the user in order for the user to get access to their own files. There are two basic types of ransomware: 1) crypto ransomware and 2) locker ransomware.
Crypto Ransomware (data locker)
This is the most common ransomware which aims to prevent access to data and files by encrypting them. This malware will find and encrypt valuable data stored on the computer making the data useless unless the user obtains the decryption key.
Locker Ransomware (computer locker)
This malware is designed to deny access to the computer or device by locking it. This ransomware utilizes social engineering techniques to pressure victims into paying. Examples of social engineering techniques include masquerading as law enforcement authorities, or showing pornographic images to embarrass the user who feels pressured to pay the fine.
Businesses As Targets
Business computers that contain business plans, databases, forms, proposals, reports, source code, and tax compliance documents are primary targets for ransomware threats. Symantec reports that modern crypto ransomware threats can catalog all accessible drives, such as local file-share servers, and encrypt files on these as well. More than one system can be impacted by just a single crypto ransomware infection the loss of which can have a catastrophic impact on the business.
