Ransomware is a word that has, unfortunately, become more common in our lexicon. With a spate of high-profile incidents in recent times, understanding ransomware is crucial, not just for IT professionals, but for anyone who uses a computer. In this article, we’ll delve into the basics of ransomware, highlighting notable incidents and their impact. (Definition)
What is Ransomware?
At its core, ransomware is malicious software, or malware, that encrypts a victim’s files. The attacker then demands a ransom from the victim to restore access to the data upon payment. In many cases, the ransom amount is demanded in cryptocurrencies like Bitcoin to maintain the anonymity of the cybercriminal.
Ransomware can target any user, be it an individual, a small business, or a large corporation. It doesn’t discriminate. Once it infiltrates a system, the malware will lock (encrypt) files, making them inaccessible. The user is then greeted with a message explaining that their files have been locked and will only be released upon the payment of a ransom.
Notable Ransomware Incidents and Their Impact
– WannaCry (2017): Probably the most infamous ransomware attack to date, WannaCry affected over 230,000 computers across 150 countries in a matter of days. Hospitals, businesses, and public services were thrown into chaos. The financial cost was estimated to be in the billions of dollars, but the real impact was felt by ordinary people – patients who had their treatments delayed, customers who couldn’t access services, and employees who were unable to work.

– NotPetya (2017): Just a month after WannaCry, NotPetya struck, initially targeting Ukraine but quickly spreading worldwide. While it posed as ransomware, its primary purpose seemed to be destruction. Companies like Maersk, the world’s largest shipping firm, and Merck, a global pharmaceutical company, faced disruptions that cost them hundreds of millions. CISA Alert

An estimated $2.7 million. Wikipedia
– Colonial Pipeline (2021): In a significant attack on critical infrastructure, the Colonial Pipeline, which provides nearly half the fuel supply to the U.S. East Coast, was forced to shut down its operations due to a ransomware attack. The company eventually paid a ransom of $4.4 million, showcasing the tangible threat of ransomware to national security. CISA News
Ransomware isn’t just a buzzword – it’s a genuine threat in our increasingly digital world.
