The recent ransomware attack on London hospitals by the Russian group Qilin has sent shockwaves through the healthcare sector. The attack, which occurred on June 3rd, targeted the NHS provider Synnovis, causing the cancellation of hundreds of operations and appointments. The impact of the attack was felt particularly in southeast London, where hospitals such as King’s College and Guy’s and St Thomas’ were severely affected. The attack also disrupted services such as blood transfusions, leading to a memo to staff labeling it as a “critical incident.”
One of the major concerns arising from the attack is the reported data dump of patient records. According to reports, almost 400GB of data, including patient names, dates of birth, and descriptions of blood tests, were shared by Qilin on their darknet site and Telegram channel. This has raised significant privacy and security concerns, especially given that the stolen records reportedly cover 300 million patient interactions, including sensitive information such as blood test results for HIV and cancer.
In response to the attack, NHS England has set up a website and helpline to assist affected patients. The National Crime Agency has confirmed that it is leading the criminal investigation into the incident. However, verifying the data included in the published files is proving to be a complex and time-consuming process, with NHS England warning that investigations of this nature can take weeks, if not longer, to complete. The situation is further complicated by the fact that most ransomware gangs are based in former Soviet states, making them difficult to apprehend and bring to justice.
Ransomware attacks, like the one on London hospitals, have become increasingly common and are considered one of the costliest and most disruptive forms of cybercrime. These attacks target a wide range of organizations, including local governments, court systems, hospitals, and schools. The attackers typically paralyze computer systems with malware and demand payment in exchange for releasing them. In the case of Qilin, they lease malware to affiliates who carry out attacks on their behalf in exchange for a percentage of the ransom payments.
The ransomware attack on London hospitals serves as a stark reminder of the growing threat posed by cybercriminals to organizations across various sectors, including healthcare. The incident highlights the need for robust cybersecurity measures and rapid response mechanisms to mitigate the impact of such attacks. As the investigation into the attack continues, it is imperative that organizations and authorities work together to identify and apprehend those responsible and prevent future attacks from occurring.
