  3. Odido confirms major breach:
    • 688,102 accounts added to HIBP
    • ~6M records potentially exposed
    • ShinyHunters claims responsibility
    • Ransom refused — data leaked in stages

  4. UNC3886 leveraged ORB infrastructure for stealthy telecom targeting.

    Per Cyber Security Agency of Singapore:
    • Zero-day firewall compromise
    • Rootkit persistence mechanisms
    • GOBRAT & TINYSHELL C2 nodes
    • ORB-tagged IP clustering in Singapore ASNs
    • NetFlow-confirmed router-to-ORB communications
    • Pre-positioned reconnaissance

    Attribution aligned with assessments from Mandiant linking activity to China-sponsored espionage.

    ORB networks blur the line between botnets and residential proxy ecosystems, increasing attribution friction and collateral risk.

    Defensive priorities:
    • Threat intel enrichment
    • Edge device patch enforcement
    • ASN anomaly detection
    • Zero-trust segmentation
    • IoT telemetry visibility

    How mature are ORB detection capabilities in your SOC?

  6. UNC3886 targeted Singapore’s telecom infrastructure, impacting Singtel, StarHub, M1 & Simba.

    Limited access, small technical data exfiltration, no customer data exposed.

  7. Reporting indicates a prolonged telecom-focused intrusion campaign may have affected mobile communications of UK government aides, with attribution linked by U.S. sources to Salt Typhoon.

    The case reinforces concerns around persistent access, metadata exposure, and call interception - particularly where legacy telecom systems intersect with modern threat actors.

    From a defensive standpoint, where should governments prioritize: network hardening, endpoint security, or telecom architecture redesign?

  8. Brightspeed has acknowledged an ongoing investigation into alleged unauthorized access following claims made by a known threat group.

    The case underscores the importance of evidence validation, controlled disclosures, and coordinated response when dealing with public claims of data exfiltration - especially in large telecom environments.

  10. Two former Cisco Networking Academy students have been linked to the Salt Typhoon campaign, which has compromised 80+ global telecom providers. Investigators say the attackers used technical skills learned directly from Cisco’s curriculum to target IOS and ASA devices.

    This case reignites debate over whether corporate training programs in politically tense regions may inadvertently strengthen future threat actors.

  12. DoT has clarified that the Telecom Cyber Security (TCS) Amendment Rules 2025 remain active, despite a duplicate Gazette publication being withdrawn.

    The updates introduce MNV-based identity validation, enhanced IMEI verification for resold devices, and tighter coordination with TIUEs handling telecom identifiers - all with data-protection guardrails.

    Thoughts from the security community on the practical impact?

  15. 📞 Caller ID spoofing is now industrialized.
    Europol urges a unified European framework to stop “spoofing-as-a-service” kits enabling large-scale impersonation scams.

    Losses exceed €850M annually, with law enforcement calling for cross-border cooperation and technical standards to trace calls.
    Can telecoms realistically close this gap - or do we need new protocols at the network level?

  18. Weekly output: Ford’s EV strategy, Open RAN security risks, Waymo + Spotify

    After a week and a half on the West Coast that began with Black Hat, I can now turn my attention to catching up on the talks I had to skip at that conference, since on-demand video is now available for all but a handful of its sessions. Video of some DEF CON talks is also now starting to pop up, and I’m looking forward in particular to seeing the Voting Village talks that I missed because I bugged out of Vegas Friday afternoon of that week.

    Patreon readers got a recap of Black Hat that included some observations about Washington’s wilted presence at this security conference and the generally skeptical take of conference speakers on AI hype.

    8/11/2025: Ford Announces $5B Plan to Make EVs Cheaper, Starting With $30,000 Pickup, PCMag

    With PCMag’s automotive writer traveling, I stepped in to write this breakdown of the automaker’s ambitious plan to reinvent electric-vehicle production. I hope Ford can deliver on this, and I hope the coming family of cheaper EVs will include a four-door hatchback (even if they call it an SUV or a crossover because it’s a little taller than a sedan).

    8/14/2025: Researchers recap some security downsides to open RAN, Light Reading

    This Black Hat briefing on Thursday of the previous week about possible vulnerabilites in Open RAN (Radio Access Network) sites went much deeper in the weeds than I usually get when covering telecom infrastructure. So I took an extra couple of days to look over the presentation again, read the reports linked to from it, listen again to my recording of the session, and briefly quiz researchers Tianchang Yang and Kai Tu over e-mail. And then I somehow typed two numbers wrong in the same graf, both of which I’d had correct in my notes. Fortunately, my editor quickly fixed those flubs after Yang brought them to my attention.

    8/16/2025: Waymo Picks Up Spotify: Cue Up Personal Playlists on Robotaxi Rides, PCMag

    I found out about this change to the Waymo ride experience not from one of that Alphabet subsidiary’s social-media posts, a note from any of its publicists, or an announcement on its site, but from an e-mail I got as a Waymo customer Friday morning. I felt a little bad learning that Waymo had posted this news on four different social platforms Tuesday, but then I realized that earlier news coverage had not mentioned Waymo’s removal of online documentation about an older, jankier way to play music from your phone through a Waymo robotaxi’s speakers.

  29. "🔍 Unveiling Sandman APT: The Silent Menace Targeting Global Telcos 🎯"

    SentinelLabs has unearthed a new threat actor dubbed Sandman APT, primarily targeting telecommunication providers across the Middle East, Western Europe, and South Asia. This enigmatic group employs a novel modular backdoor named LuaDream, utilizing the LuaJIT platform, a rarity in the threat landscape. The meticulous movements and minimal engagements hint at a strategic approach to minimize detection risks. The LuaDream malware, a well-orchestrated and actively developed project, is designed for system and user info exfiltration, paving the way for precision attacks. The intriguing part? The attribution remains elusive, hinting at a private contractor or a mercenary group akin to Metador. The activities observed are espionage-driven, with a pronounced focus on telcos due to the sensitive data they harbor. The meticulous design of LuaDream showcases the continuous innovation in the cyber espionage realm, urging for a collaborative effort within the threat intelligence community to navigate the shadows of the threat landscape.
