Ransomware – How to Protect Your Computer From Ransomware Attacks
Ransomware is a malware variant that seeks to extort victims by encrypting their files and demanding payment to decrypt them. Attackers use phishing emails and social engineering techniques to infect computers, then scan the system for valuable files that can be encrypted. Once the malware has been introduced, the victim must follow instructions on a ransom note to pay a specified sum in Bitcoin or other cryptocurrency to unlock the files.
Despite global efforts to disrupt cyber crime, ransomware attacks are growing. Attacks on businesses, governments and healthcare organizations are now a normal occurrence and there are no signs that these incidents will slow down any time soon.
In 2024 alone, healthcare was the most targeted industry with more than 1500 attacks, followed by government and military and communications organizations. Attacks on critical infrastructure are also surging, with industrial, commercial facilities and healthcare sectors at increased risk.
While some attackers have been caught and prosecuted, the vast majority are not. Instead, they will continue to wreak havoc, stealing sensitive data and holding it hostage for a ransom payment. These criminals will also invest their profits into developing even more nefarious strains that may find their way onto your systems in the future.
Even if you pay the ransom, there’s no guarantee you’ll receive a good decryptor key. And it’s not unheard of for the encryption process itself to corrupt a file beyond repair. Additionally, paying a ransom funds criminal activity and could expose you to legal or regulatory penalties for security negligence.
