Users are urged to follow Bluetooth security guidance and contact Apollo Pharmacy for vendor-specific information.

🔒 AVer PTC500S, PTC115, PTC500+, and PTC115+ cameras contain an input validation flaw that could permit unauthenticated remote arbitrary code execution via a crafted web request. Affected devices are rated CVSS v3 9.8 and relate to CWE-552 Files or Directories Accessible to External Parties. AVer has released firmware to address the issue and CISA advises minimizing network exposure, placing devices behind firewalls, and using secure remote access methods such as updated VPNs.

🔒 The advisory describes vulnerabilities in Brickcom cameras that permit unauthenticated attackers to access live snapshots via the /ONVIF endpoint and exploit default credentials to obtain administrative control. CISA reports vendor non-coordination and urges users to contact Brickcom for support while following defensive measures. Recommended mitigations include isolating devices behind firewalls, minimizing internet exposure, and using secure remote access methods such as updated VPNs.

🔒 Yarbo mobile apps and cloud infrastructure expose hard-coded MQTT broker credentials and lack per-device authorization, enabling broad access to telemetry and command topics across the robot fleet. The vulnerability allows wildcard subscription to telemetry and publishing to individual robot command topics using only a serial number. Yarbo recommends updating the mobile app to 3.17.4 or later; server-side broker authorization will be enforced with the May 2026 update. CISA advises network restrictions, isolation behind firewalls, and use of secure remote access methods while organizations perform risk assessments.

🔒 CISA published an advisory on multiple critical vulnerabilities in the Naxclow IoT Platform that allow device impersonation, credential exposure, and fleet enumeration. A replayable onboarding flow and inadequate authorization let attackers reassign devices, while persistent, non-rotating relay credentials enable long-term access. Additional weaknesses include a hard-coded platform salt for request signing, predictable device identifiers, and cleartext Wi‑Fi secrets exposed via UART.

🔍 Lumen’s Black Lotus Labs reports a China-linked botnet called JDY has grown to over 1,500 compromised SOHO and IoT devices used to rapidly discover and fingerprint internet-facing systems after public vulnerability disclosures. The activity, tied to nation-state actors including Volt Typhoon, enables persistent, distributed reconnaissance that can evade geofencing and IP-reputation controls. Researchers warn this marks a shift toward industrialized pre-exploitation scanning and undermines traditional perimeter patch and monitoring assumptions.

🔍 A reverse-engineered iOS SDK from Bright Data reveals free apps can turn devices, including always-on smart TVs, into exit nodes that relay web-scraping traffic. The SDK, embedded behind opt-in screens, uses peer channels with weak authentication and can bypass VPNs on iOS, allowing background relays that consume home bandwidth. Blocking a handful of SDK domains at the router or scanning apps on managed devices can stop the behavior.

🔧 AWS IoT Device Management now surfaces MQTT session data in its connectivity status API, helping teams troubleshoot device connectivity and audit connection patterns across IoT fleets. The update provides session timeout and expiry values and, optionally, socket-level details like source/destination IPs, ports, and client VPC endpoint IDs. Access to socket information is controlled by granular IAM policies. The API keeps connection records indefinitely, exceeding the 30-minute retention of AWS IoT Core's GetConnection API.

🔍 AWS IoT Core now emits two new Amazon CloudWatch Log event types to help troubleshoot device connectivity and authentication across IoT fleets. The Ping log captures MQTT Keep‑alive messages to identify connections or devices that fail to maintain connectivity. The Connection.AuthNError log records rejected connection attempts with detailed error codes to speed resolution of credential and certificate issues. Enable event-level logging and choose a CloudWatch log group, then opt into these event types; they are available in all AWS Regions where AWS IoT Core operates.

🔧 AWS IoT Core introduces two MQTT connection management APIs: GetConnection and ListSubscriptions. These APIs provide detailed visibility into device MQTT connections and subscriptions, including session details and optional socket-level data, controlled by granular IAM policies. They complement the existing DeleteConnection API to offer a fuller connection management capability available in all supported AWS regions.

🔔 AWS IoT Core now supports direct point-to-point messaging to any connected device, enabling delivery acknowledgements and improved visibility into message status.
