Bransys ELD
CISA reports Bransys ELD apps ship hardcoded MQTT and FTP credentials plus cleartext transport, exposing real-time telemetry for connected fleet devices.
CISA's advisory covers three Bransys ELD mobile app flaws: CVE-2026-86520 hardcoded MQTT credentials (CVSS 7.5), CVE-2026-86689 cleartext transmission of sensitive information, and CVE-2026-77960 hardcoded FTP credentials. Exploitation could allow unauthorized reading of real-time telemetry data from every active device connected to affected brokers across a subset of carriers. Android versions below 11.00.00 and iOS versions below 1.1.54 are affected; no public exploitation has been reported to CISA.
- Hardcoded MQTT credentials expose real-time telemetry for all devices on carrier brokers
- CVE-2026-86689 allows cleartext data interception by anyone connecting to the broker
- Hardcoded FTP credentials (CVE-2026-77960) permit reading data on the server
- Android below 11.00.00 and iOS below 1.1.54 are affected

Recommended Practices
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities.
- Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
- Locate control system networks and remote devices behind firewalls and isolating them from business networks.
- When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
CISA also recommends users take the following measures to protect themselves from social engineering attacks:
- Do not click web links or open attachments in unsolicited email messages.
- Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.
- Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.
No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.
