Ransomware is a form of malicious software designed to encrypt a victim’s files and/or system, then demand a ransom fee from the victim in exchange for the restoration of access to the files and/or system. Over the years, ransomware has become the biggest threat to businesses of all types – from governmental agencies to healthcare organizations to small shops and everything in between – with ransom fees growing as time goes on.
The average ransom fee as of lately? A staggering $13,000.
In the past, ransomware attacks relied on mass phishing emails sent out to a huge amount of people with the goal of getting a few hits. Nowadays, cybercriminals are launching more focused, sophisticated attacks:
- Abusing stolen credentials to gain access to systems
- Exploiting vulnerabilities in remote desktop protocols
- Creating phony domains designed to entice downloads
How Does Ransomware Work?
It’s important to understand exactly how ransomware works, in order to prepare yourself and stay protected:
- Attackers deliver the malware payload to the target via a phishing attack, gaining access to the systems or enticing them to download it somehow.
- The malware reaches out to the cybercriminals to let them know a victim has been infected and it’s time to encrypt their data and/or systems.
- The data and/or systems are encrypted – often starting with the local disk, then moving onto mapped shares or open shares.
- The victim receives a ransom note from the cybercriminal demanding a specific dollar figure in the form of cryptocurrency in exchange for the decryption key.
