HEADLINE PRIVACY & IT SECURITY COMPLIANCE NEWS

In May 2023, a security flaw (CVE-2023-2868) in Barracuda Email Security Gateway (ESG) was exploited by a Chinese cyberespionage group, UNC4841, in October 2022. Mandiant confirmed UNC4841's involvement. The hackers used the flaw to deploy malicious software, and despite Barracuda issuing patches, the attacks persisted. On Christmas Eve, Barracuda revealed a new flaw (CVE-2023-7102), exploited by UNC4841 to deliver malware through Excel files. Barracuda released a patch and advised addressing another vulnerability (CVE-2023-7101) in the 'Spreadsheet::ParseExcel' library. UNC4841 had previously targeted entities in 16 countries, including governments, academics, and foreign trade offices.

A cybersecurity breach at Comcast's residential cable unit, Xfinity, has exposed confidential information of nearly 36 million customers. The breach occurred due to hackers exploiting a critical vulnerability named Citrix Bleed, embedded in Citrix networking devices widely used by major corporations. The delay in implementing Citrix's October patches left many vulnerable. Hackers used Citrix Bleed to access Xfinity systems in mid-October, compromising customer information such as usernames, scrambled passwords, names, contact info, birth dates, parts of Social Security numbers, and answers to security questions. Citrix recommends users update their devices promptly to address security issues.
