Ransomware is one of the most dangerous cyber threats today. It’s a type of malicious software that locks your files and demands payment (a ransom) to unlock them.
What’s New This Year?
Hackers are now using double extortion tactics:
- They lock your files.
- They steal your data and threaten to publish it online if you don’t pay.
This means even if you have backups, you could still be at risk of sensitive information being leaked.
How Ransomware Works
- You click a dangerous link or download a fake file.
- The ransomware installs itself on your computer.
- It encrypts (scrambles) your files so you can’t open them.
- You get a message demanding payment, often in cryptocurrency like Bitcoin.
Encryption is a way of changing data into a secret code so only someone with the right key can read it.
Recent Trends
- Targeting small businesses: Hackers know smaller companies often have weaker security.
- Faster attacks: Some ransomware can encrypt thousands of files in minutes.
- AI-assisted attacks: AI helps hackers find the most valuable files to lock.
Real Case
In mid-2025, a hospital was hit by ransomware. Hackers demanded $2 million, threatening to leak patient records. The hospital had backups but still paid because of the privacy risk.
How to Protect Yourself
- Regular backups: Store copies of your files offline.
- Don’t click unknown links: Be careful with emails from strangers.
- Use strong passwords: Avoid simple ones like “123456”.
- Train employees: Teach staff how to spot suspicious emails.
Conclusion
Ransomware is evolving, and paying the ransom doesn’t guarantee safety. Prevention and awareness are your best defenses.
