Picture yourself waking up one morning, booting up your computer, and being met with a cold message: "Your files have been encrypted. Pay $500 in Bitcoin to regain access." That's the horror of ransomware. It's not the plot from a hacker flick it's an emerging cyber threat that can affect anyone, from individuals and companies to even governments.
Ransomware is a form of malicious software that encodes your files and asks for money to release them. Consider it a cyber kidnapper that holds your documents for ransom.
The attack typically begins with an infection frequently via a harmful link, email attachment, or security flaw. The files get encrypted once inside, and they become inaccessible until you input the decryption key, something the thief vows to offer once payment has been made.
Ransomware attacks have grown exponentially in recent years, with hospitals, schools, and companies being targeted by cyberthieves. Worldwide damages will cost billions each year, so prevention is more critical than ever.
