Have you ever heard of ransomware? It’s a nasty type of malware that locks up your files or systems and asks for money to unlock them. If you don’t pay, you might lose your data forever or have it leaked online. Sounds scary, right?
Ransomware has been around for a while, but it’s getting more advanced and common these days. According to a report by CISA, there were almost 200 million ransomware attacks in the first half of 2018, which is more than double the number from the same period in 2017. Some of the most famous ransomware attacks include WannaCry, which hit over 200,000 computers in 150 countries in 2017; Petya/NotPetya, which targeted businesses and critical infrastructure in Ukraine and other countries in 2017; and Colonial Pipeline, which shut down the largest fuel pipeline in the US for six days in 2021.
So how does ransomware work? Usually, it comes as a Trojan that pretends to be a normal file that you download or open from an email or a website. But once you do, it encrypts your files or systems and shows you a ransom note. Sometimes, ransomware can also spread by itself through networks or exploit weaknesses in software or systems. Ransomware attackers often ask for payment in cryptocurrencies like Bitcoin, which are hard to track and get back.
How can you protect yourself from ransomware? Here are some tips:
- Back up your important files regularly and keep them offline or on a separate device.
- Update your software and systems with the latest security patches and antivirus software.
- Don’t open suspicious email attachments or links from unknown senders or sources.
- Learn about the risks and signs of ransomware and how to report incidents.
- Have a plan and a team ready in case of a ransomware attack.
Ransomware is a serious cyber threat that can have terrible consequences for its victims. By following these tips, you can reduce your chances and impact of ransomware attacks.
