'SalesBleed' security flaws 'lead to very unexpected consequences'
The Hacker News
OpenAI on Wednesday disclosed six new instances of "unexpected or concerning model behavior" that took place over the past six months, while sharing a new framework for reporting, tracking, investigating, and disclosing model misalignment in a bid to improve transparency. "As AI systems grow more advanced and more widely deployed, we need to build a broader and better-informed consensus on the

Microsoft has finally fixed a known issue that was causing systems running Windows Server 2019 and 2022 to "unexpectedly" upgrade to Windows Server 2025. [...]
The Hacker News
Some weeks in cybersecurity feel routine. This one doesn’t. Several new developments surfaced over the past few days, showing how quickly the threat landscape keeps shifting. Researchers uncovered fresh activity, security teams shared new findings, and a few unexpected moves from major tech companies also drew attention. Together, these updates offer a useful snapshot of what is happening
The Hacker News
This week’s updates show how small changes can create real problems. Not loud incidents, but quiet shifts that are easy to miss until they add up. The kind that affects systems people rely on every day. Many of the stories point to the same trend: familiar tools being used in unexpected ways. Security controls are being worked on. Trusted platforms turning into weak spots. What looks routine on
CISA advisories
Overview The Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), Health and Human Services (HHS), U.S. Department of Agriculture (USDA), and the Department of Transportation (DoT)—hereafter referred to as “the authoring organizations”—are aware of malicious cyber activity targeting industrial refrigeration and cold chain monitoring systems globally. Organizations in the Healthcare and Public Health, Chemical, Food and Agriculture, and Transportation Systems Sectors widely use these systems, including in refrigerated transport services, for automated and remote monitoring of temperatures, continuous temperature logging, defrost cycle management, and energy optimization. The authoring organizations urge owners and operators to defend against this activity by using strong authentication, keeping systems updated, identifying any systems that are accessible from the internet, removing unnecessary remote access, and securing any necessary remote access. Threat The authoring organizations are aware of malicious cyber actors targeting electronic temperature controllers and commercial refrigeration controllers in retail grocery and cold storage facilities. The actors may exploit vulnerabilities or weaknesses in unpatched or internet-accessible controllers to remotely alter settings and force units into continuous heating and defrost cycles, which can cause widespread inventory loss and equipment hazards. Specifically, the actors may exploit these flaws through multiple vectors: Authentication bypass; Arbitrary code injection; and Weak configurations. Upon successful exploitation of the flaws, the actors could achieve the following effects: Change of temperature, which could: Affect the service life of the system; Create a fire hazard; Cause loss of inventory; or Indirectly harm consumers if products are consumed after unsafe storage. Loss of visibility into current temperatures (a denial-of-view condition). Mitigations The authoring organizations urge owners and operators to immediately take the following actions. These mitigations align with the Cross-Sector Cybersecurity Performance Goals (CPGs), developed by CISA and the National Institute of Standards and Technology (NIST). The CPGs provide a minimum set of practices and protections that CISA and NIST recommend all organizations implement: Eliminate public internet exposure: Do not expose control system devices and/or systems, particularly controller panels, to the internet [CPG 3.S]. Should remote access be necessary, protect it by using a firewall or edge device and updating it to the latest version to reduce security vulnerabilities. See CISA’s Internet Exposure Reduction Guidance and Defend the Edge: The Critical Importance of Edge Device Security for additional guidance on securing edge devices. Isolate operational technology (OT) devices: Create a dedicated OT virtual local area network (VLAN) to separate OT devices from business networks [CPG 3.I]. Enforce credential security: Change default passwords [CPG 3.A], strengthen passwords, and implement strong password policies [CPG 3.B]. Further, implement phishing-resistant multifactor authentication wherever feasible [CPG 3.F]. Apply patches: Keep device firmware up to date and establish a structured lifecycle management process to identify, retire, and replace legacy devices that are at end of life (EOL) and no longer supported by the manufacturer [CPG 2.A, 2.B]. See CISA’s BOD 26-04: Implementation Guidance for Prioritizing Security Updates Based on Risk and BOD 26-02: Mitigating Risk From End-of-Support Edge Devices for additional guidance. Restrict access: Define and maintain device and IP address allowlisting, limiting access to only those devices and IP addresses authorized to make changes [CPG 3.H]. Have reliable backups: Maintain current backups offsite and offline and test them [CPG 3.O]. Monitor and report: Enable logging [CPG 3.Q] and regularly review logs for unexpected activity. For OT assets where logs are non-standard or not available, collect network traffic and communications between the assets. Review setpoint ranges: Define and maintain reasonable setpoint limits for devices operating downstream of controllers to stay within safe ranges and establish alerting for deviations. Resources The authoring organizations strongly urge industrial refrigeration and cold chain monitoring system owners and operators to secure remote access to their OT systems. To strengthen system security, owners and operators should review the following resources and implement recommended mitigations: CISA: Primary Mitigations to Reduce Cyber Threats to Operational Technology CISA: Defend the Edge: The Critical Importance of Edge Device Security CISA: Internet Exposure Reduction Guidance United Kingdom’s National Cyber Security Centre and Partners: Secure Connectivity Principles for OT Contact Information The authoring organizations recommend U.S. organizations report suspicious or criminal activity related to information provided in this fact sheet: Contact CISA via CISA’s 24/7 Operations Center at contact@cisa.dhs.gov or 1-844-Say-CISA (1-844-729-2472). For more information on reporting a cyber incident, refer to CISA’s Voluntary Cyber Incident Reporting web page. File a claim with FBI’s Internet Crime Complaint Center (IC3) or contact your local FBI field office. When available, please include the following information regarding the incident: Date, time, and location of the incident; Type of activity; Number of people affected; Type of equipment used for the activity; and Name of the submitting company or organization, and a designated point of contact. Contact HHS via HHSCyber@hhs.gov or the HHS 24/7 Operations Center at 202-619-7800 for assistance mitigating potential disruptions to the delivery of healthcare resulting from health and medical supply chain impacts.

Graham Cluley
Graham gets a phone call from the police. Well, someone who sounds convincingly like the police. There's just one small problem: what they really want is the 24-word seed key to Graham's cryptocurrency wallet. Meanwhile, if you've stayed in a hotel recently, the free Wi-Fi you connected to might have come with an unexpected extra: an all-you-can-eat buffet of "Captive Crunch" for a Russian intelligence-linked hacking group. And a group calling itself the "ExFilSquad" has walked off with 600,000 records of the UK's teachers and head teachers from the Department for Education — sending an unusually polite ransom demand. All this and more in episode 479 of the "Smashing Security" podcast with cybersecurity expert and keynote speaker Graham Cluley, and special guest Danny Palmer.
