As we’ve reported before, the ransomware threat has many negative effects. Ransomware “is malware. The hackers demand payment, often via Bitcoin or prepaid credit card, from victims in order to regain access to an infected device and the data stored on it.” [Ransomware: The Smart Person’s Guide, by James Sanders]
How pervasive is the threat of ransomware in our everyday lives? Check out this rather scary cartoon from Joy of Tech. It was inspired by the recently published Ransomware: Defending Against Digital Extortion by Allan Liska and Timothy Gallo! [Click the image for a larger version of the cartoon.]
The term “ransom” has been around for hundreds of years and is best described as a way to redeem someone from captivity, bondage, detention, etc., by paying a demanded price.
Today, we have another destructive variation of the word ransom — that is “ransomware.” What is it and what can we do about it?
TechRepublic recently produced Ransomware: The Smart Person’s Guide, written by James Sanders. This is an executive summary quoted from the guide:
- What is it? Ransomware is malware. The hackers demand payment, often via Bitcoin or prepaid credit card, from victims in order to regain access to an infected device and the data stored on it.
- Why does it matter? Because of the ease of deploying ransomware, criminal organizations are increasingly relying on such attacks to generate profits.
- Who does this affect? While home users have traditionally been the targets, healthcare and the public sector have been targeted with increasing frequency. Enterprises are more likely to have deep pockets from which to extract a ransom.
- When is this happening? Ransomware has been an active and ongoing threat since September 2013.
- How do I protect myself from a ransomware attack? A variety of tools developed in collaboration with law enforcement and security firms are available to decrypt your computer.
Sanders adds: “For those who have been infected, the No More Ransom project — a collaboration between Europol, the Dutch National Police, Kaspersky Lab, and Intel Security — provides decryption tools for many widespread ransomware types.
