Notable Incidents:

  • Synnovis Attack: In June 2024, Synnovis, a laboratory services provider for the UK's National Health Service, suffered a ransomware attack by the Qilin group. The incident led to the theft of 400GB of patient data, causing widespread disruptions in medical services across London. The financial impact was severe, with losses amounting to £32.7 million, far exceeding the company's £4.3 million profit from the previous year.

  • BlackCat/ALPHV Takedown: In December 2023, the FBI disrupted the BlackCat (also known as ALPHV) ransomware group by seizing multiple websites and releasing a decryption tool for victims. Despite this, the group continued its activities into 2024, including an attack on Hong Kong's Consumer Council in May.

  • Rhysida Group Activities: The Rhysida ransomware group emerged as a significant threat in 2024, targeting various organizations, including the British Library and Insomniac Games.

  • LockBit ransomware group intensified its attacks on the financial sector, notably targeting banks and financial institutions. A significant incident occurred in June 2024 when Evolve Bank & Trust, an Arkansas-based institution, suffered a cyberattack attributed to LockBit. The breach led to the exposure of customer data on the dark web, prompting the bank to involve law enforcement and offer affected customers credit monitoring and identity theft protection services.

The incident highlights the critical need for robust cybersecurity measures within the banking sector to safeguard against such sophisticated threats. 

Evolving Tactics:

Ransomware groups have adopted more sophisticated methods, including double extortion tactics where they not only encrypt data but also threaten to publish it unless ransoms are paid. The emergence of new groups like Rhysida and the persistence of established ones like LockBit underscore the dynamic and evolving nature of ransomware threats.
