Security experts are warning businesses of all sizes to stay alerted for ransomware and maladvert attacks against them. In fact, the Federal Bureau of Investigation renewed its warnings concerning the increasing pace of ransomware.
Fact Check: What is Ransomware?
Ransomware is malware downloaded on an individual’s computer or a business’s computer system, Once the virus is unleashed, it freezes a computer or a computer system making it useless. To get files unlocked, victims pay a ransom, usually in Bitcoins. Most often, the ransomware is attached to an email.
Initially, ransomware targeted home computer users. The cyber criminals asked for small ransoms – often less than $100. Usually, home users directly paid the ransom, and their computers were released from being frozen. It wasn’t long before the criminals trolling the internet realized that if home users paid, businesses would too. They were right, and in 2016 ransomware became the number one security scourge for business.
Interestingly, when companies do pay the ransom, they get their systems and data decrypted. Knowing this helps cyber gangs keep the scam going as businesses think it is cheaper to pay than prevent a ransomware attack.
