Health Service Executive Ransomware Attack
Edit
The content is sourced from: https://handwiki.org/wiki/Medicine:Health_Service_Executive_ransomware_attack

On 14 May 2021, the Health Service Executive (HSE) of Ireland suffered a major ransomware cyberattack which caused all of its IT systems nationwide to be shut down. It was the most significant cybercrime attack on an Irish state agency and the largest known attack against a health service computer system. Bloomberg News reported that the attackers used the Conti ransomware. The group responsible was identified as a criminal gang known as Wizard Spider, believed to be operating from Russia. The same group is believed to have attacked the Department of Health with a similar cyberattack. On 19 May, the Financial Times reviewed private data for twelve individuals which had appeared online as a result of the breach. On 28 May, the HSE confirmed confidential medical information for 520 patients, as well as corporate documents were published online. On 23 June, it was confirmed that at least three quarters of the HSE's IT servers had been decrypted and 70% of computer devices were back in use. By September, over 95% of all servers and devices had been restored.
