Lessons Learned From The Biggest Ransomware Attacks - Cybercrime Magazine
Ransomware has become the fastest-growing cybercrime, with global damage predicted to exceed $265 billion by 2031, according to Cybersecurity Ventures.
The most expensive ransomware attacks since 2023 have targeted major companies across various sectors, causing billions in damages and operational disruptions. These incidents demonstrate that no industry is immune to cyber extortion.
Healthcare System Paralyzed
Change Healthcare, a giant healthcare payment processor, was paralyzed in February 2024 when ransomware infiltrated its systems. Attackers exfiltrated over 6 terabytes of sensitive health and financial data, severely disrupting claims processing across the United States.
The attack affected an estimated 40% of all U.S. medical claims, delaying prescription fulfillment, billing, and reimbursements nationwide. Beyond the $22 million ransom payment, the total cost of the attack reportedly reached $2.87 billion.
Major Companies Targeted
Six other major ransomware attacks hit Jaguar Land Rover, Marks & Spencer, CDK Global, MGM Resorts, Royal Mail, and Cencora. These incidents show that any company, regardless of sector, can fall victim to ransomware and be extorted for millions of dollars.
ProLion, developers of CryptoSpike, a solution to protect storage systems from ransomware, has analyzed these attacks to understand what could have been done differently to prevent such costly breaches.
