•[ cyber espionage, vulnerability exploitation, SSH brute force ]
BleepingComputer reported on Cisco Talos research describing a sophisticated China-nexus actor tracked as UAT-7290 targeting telecommunications providers, historically in South Asia and recently expanded into Southeastern Europe. The group was described as conducting extensive reconnaissance and using one-day exploits plus target-specific SSH brute force to compromise public-facing edge devices for initial access and privilege escalation. Talos reported the actor deploys a primarily Linux-based malware suite (with occasional Windows implants) and establishes Operational Relay Box (ORB) infrastructure that can be used by other China-aligned threat actors. The report is campaign-level and does not enumerate a single named victim breach event date.

•[ vulnerability exploitation, data leak, third-party breach ]
A cybercrime group exploited a URL redirection vulnerability in a third-party contractor system for StubHub to steal around 1,000 digital tickets for major events, including Taylor Swifts Eras Tour. The stolen tickets, valued at approximately $635,000, were resold online for profit. The scheme operated between June 2022 and July 2023 before being uncovered through a coordinated investigation by cybersecurity and law enforcement agencies. Two individuals, Tyrone Rose and Shamara P. Simmons, were arrested and charged with grand larceny, identity theft, and computer tampering in connection with the operation.
