What Is Ransomware? A Primer For IT Professionals
Backup Central, Monday, January 19th, 2026
The question sounds almost too basic for 2026: what is ransomware? Yet tens of thousands of people search for this term every single month. And here's the truth-even seasoned IT professionals need to revisit this topic because ransomware attacks have changed dramatically over the past few years.
This blog post summarizes the main points of my latest podcast episode.
At its core, ransomware is malicious software that gains access to your systems, encrypts your data, and demands payment (usually in Bitcoin) for the decryption key. The name comes from the concept of holding your data for ransom-they've taken it from you, and you can have it back if you pay up.
The traditional attack works like this: someone clicks a bad link or opens a malicious attachment, the malware installs itself, encrypts everything it can reach, and then you see that lovely screen asking for cryptocurrency. Simple, brutal, effective.
