🔒 CISA, the NSA, the FBI, and international partners issued a joint advisory describing People’s Republic of China state-sponsored APT actors compromising networks worldwide to support long-term espionage. Investigations through July 2025 reveal these actors exploit vulnerabilities in large backbone provider edge and customer edge routers—often modifying firmware and configurations to evade detection and maintain persistent access. Affected sectors include telecommunications, government, transportation, lodging, and defense. The advisory urges network defenders, especially in high-risk sectors, to actively hunt for intrusions and apply the recommended mitigations.

🛡️ U.S. and international agencies warn that People's Republic of China (PRC) state-sponsored actors have been compromising global networks since at least 2021 to collect communications and other intelligence. Actors targeted telecommunications backbone routers, provider- and customer-edge devices, and infrastructure across government, transportation, lodging, and military sectors. They exploited known CVEs (for example CVE-2024-21887, CVE-2024-3400, Cisco CVEs), modified devices to maintain persistence using on-box PCAP/containers and tunnels, and exfiltrated data via peering and covert channels. The advisory includes IP indicators, binary hashes, Yara/Snort rules, hunting guidance, and prioritized mitigations to patch, isolate management planes, harden credentials, and detect PCAP creation.

🔐 Ukraine's Defence Intelligence agency (HUR) says its hackers exfiltrated classified files and technical documentation related to the newly commissioned Russian nuclear ballistic missile submarine Knyaz Pozharsky. Leaked materials, posted on Telegram, reportedly include combat manuals, schematics of combat and survivability systems, crew lists with qualifications, and operational schedules. Russian authorities have not commented and independent verification by Western intelligence or cybersecurity experts is still pending.

🔍 Thousands of North Korean IT workers have used stolen and fabricated US identities to secure roles at Western companies, funneling hundreds of millions of dollars annually to Pyongyang’s military programs. They leverage AI for resumes and cultural coaching, faceswap and VPN tools for video calls, and remote-access setups tied to US-based "laptop farms" run by facilitators who launder paychecks and ship company-issued machines abroad. Recent DOJ raids and the 102-month sentence for Christina Marie Chapman highlight legal, financial and national security risks, including potential sanctions violations.

🔒 CISA's Joint Cyber Defense Collaborative (JCDC) is coordinating with major cloud providers and federal partners to strengthen core cloud identity and authentication systems against sophisticated, nation-state affiliated threats. Recent incidents have exposed risks from token forgery, compromised signing keys, stolen credentials, and gaps in secrets management, logging, and governance. On June 25, a technical exchange convened experts from industry and government to share best practices and explore mitigations such as stateful token validation, token binding, improved secrets rotation and storage, hardware security modules, and enhanced logging to better detect and respond to malicious activity.

🔒 UpGuard secured a 1.7 TB repository that had been publicly accessible via an rsync server, containing schematics, administrative credentials, email archives, photographs, and installation materials tied to Russian telecommunications infrastructure. The dataset appears to primarily implicate Nokia and MTS, and includes detailed documentation for the SORM lawful-intercept system. UpGuard notified vendors and regulators and the files were taken offline after disclosure, though the exposure presented serious national security risks.
