Microsoft Sinkholes Notorious ZLoader Botnet
The notorious ZLoader cybercrime botnet, which was used to deliver Ryuk ransomware in attacks on healthcare providers, has been disabled by Microsoft’s Digital Crimes Unit (DCU). Microsoft recently obtained a court order from the United States District Court for the Northern District of Georgia authorizing the seizure of 65 hard-coded domains used by the ZLoader botnet for command-and-control communications. Those domains have now been sinkholed, preventing the operator of the botnet from communicating with devices infected with ZLoader malware. ZLoader malware included a domain generation algorithm (DGA) which is triggered if communication with the hard-coded domains is not possible, which serves as a failsafe against any takedown efforts. The court order also allowed Microsoft to seize 319 DGA-registered domains. Microsoft is working to block the registration of any future DGA domains. ZLoader is part of a family of malware variants that descended from the ZeuS banking Trojan. Initially, ZeuS was used for credential and financial theft, with the aim of transferring money out of...
SuperCare Health Sued Over 318,000-Record Data Breach
A lawsuit has been filed against the in-home respiratory care provider, SuperCare Health, over a cyberattack and data breach that was reported to the Department of Health and Human Services on March 28, 2022. The incident involved the exposure and potential theft of the protected health information of 318,400 patients, including names, addresses, birth dates patient account numbers, medical record numbers, health insurance information, testing, diagnostic, treatment, and claims information. A subset of individuals also had their Social Security numbers and/or driver’s license numbers exposed. SuperCare Health said unauthorized individuals had access to its network between July 23, 2021, to July 27, 2021, but did not disclose the nature of the cyberattack. It took SuperCare Health until February 4, 2022, to determine that the files potentially accessed in the attack contained patients’ PHI. Notification letters were sent on March 25, 2022, and according to the notice provided to the California Attorney General, credit monitoring and identity theft protection services were offered to...
JekyllBot:5 Vulnerabilities Allow Hackers to Take Control of Aethon TUG Hospital Robots
Five zero-day vulnerabilities have been identified in Aethon TUG autonomous mobile robots, which are used in hospitals worldwide for transporting goods, medicines, and other medical supplies. Hospital robots are attractive targets for hackers. If access to the robots is gained, a variety of malicious actions could be performed. Attackers could trigger a denial-of-service condition to disrupt hospital operations for extortion, and since sensitive patient data is fed into the devices, exploitation of the vulnerabilities could provide hackers with access to patient data. The robots are given privileged access to restricted areas within healthcare facilities, which would not normally be accessible to unauthorized individuals. The robots can open doors and access elevators, and could be used to block access, shut down elevators, or bump into staff and patients. Since the robots have integrated cameras, they could be hijacked and used for surveillance. The robots could also potentially be hijacked and used to deliver malware or could serve as a launchpad for more extensive cyberattacks...

CISA Issues Guidance on Sharing Cyber Event Information
The Cybersecurity and Infrastructure Security Agency (CISA) has recently published a fact sheet on cyber threat information sharing to guide organizations reporting cyber incidents, which will help the agency mitigate current and emerging cybersecurity threats to U.S. critical infrastructure. Following the passing of the Cyber Incident Reporting for Critical Infrastructure Act of 2022 (CIRCIA), a rulemaking process will commence to implement statutory requirements; however, the fact sheet serves as an interim measure to guide organizations through the voluntary sharing of information about cyber-related events. The sharing of cyber threat information is an essential part of the collective defense against cyber threats and helps to strengthen U.S. cybersecurity. The rapid sharing of threat information with CISA allows the agency to issue prompt warnings and provide assistance to other organizations and entities that could help them avoid falling victim to similar attacks. Having access to threat information can also help CISA to identify attack trends that will guide future efforts...
