CyberSec Roundup
A synopsis of the Latest Cybersecurity News
40 Millon Britons Exposed
The U.K. Electoral Commission has revealed a year-long undetected cyber-attack that exposed the voter data of 40 million individuals. Threat actors accessed systems in August 2021, and the breach was detected in October 2022. The attack exposed personal information like names, emails, addresses, and contact numbers of anyone in Great Britain who was registered to vote between 2014 and 2022. A risk assessment by the Information Commissioner’s Office determined that the information that was exposed does not in itself present a high risk to individuals, but could be combined with other public details (such as those on social media) for profiling purposes. It is baffling why the breach wasn’t disclosed in a timelier fashion.
Breach Affects 4 Million
The Colorado Department of Health Care Policy & Financing is warning over 4 million individuals about a data breach affecting their personal and health details. The attack by Clop ransomware exploited the MOVEit Transfer zero-day vulnerability that impacted numerous global organizations worldwide. HCPF’s systems were unaffected, but the breach occurred through their contractor, IBM, which used the MOVEit software. The breach compromised files containing sensitive information like names, Social Security Numbers, and medical details. HCPF is offering two years of credit monitoring through Experian for those affected.
TripAdvisor-Themed Knight Ransomware Spreads
Knight ransomware, a rebrand of Cyclop Ransomware, is being distributed using fake TripAdvisor complaint emails. The email will open a browser displaying a fake TripAdvisor site, that if interacted with, will download an infected Excel attachment. Users tricked into opening Excel files, will initiate the ransomware that encrypts files on the device. The ransom note demands $5,000 in Bitcoin but it isn’t likely the victims will receive the decryptor if they pay.
Rhysida Ransomware on the Rise
The Rhysida Ransomware group was only launched earlier this year, but has claimed many victims, including the Chilean army, but primarily in the healthcare sector. These attacks have caused the US Department of Health and Human Services to flag the group as a major threat to the healthcare sector.
