johnson-controlsCyber Attack60209/2023
Rankiteo Explanation :
Attack limited on finance or reputation

Description: A denial of service attack has targeted the Finnish Transport and Communications Agency Traficom once more. Access to Traficom's electronic transaction services has been restricted as a result of a service denial attack. The agency posts on the social media platform Twitter that the goal is to promptly restore services. Services are being promptly restored as the attack prevention measures take effect.

johnson-controlsRansomware75209/2023
Rankiteo Explanation :
Attack limited on finance or reputation

Description: A'massive ransomware attack' reportedly affected Johnson Controls International, encrypting many company devices, including VMware ESXi servers, and negatively affecting the business operations of both the parent corporation and its subsidiaries. Development and production of industrial control systems, security tools, air conditioners, and fire safety gear are all activities of the international company Johnson Controls. However, the incident has disrupted some of the Company's business operations and is anticipated to continue doing so. The Company is evaluating the incident's potential effects on its ability to deliver its financial results for the entire fiscal year and the fourth quarter on schedule.

Johnson ControlsVulnerability10076/2025
Rankiteo Explanation :
Attack that could injure or kill people

Description: Johnson Controls, a critical infrastructure provider, faced severe exposure of its industrial control systems (ICS) due to unpatched vulnerabilities and misconfigurations. The systems, integral to power grids, water treatment plants, and manufacturing operations, were left accessible online with default credentials or known flaws. This negligence enabled potential cyber intrusions capable of triggering catastrophic outcomes—such as blackouts, chemical contamination (e.g., tampering with chlorine levels in water utilities), or operational shutdowns in energy and healthcare sectors. The 2025 CISA advisory highlighted these vulnerabilities as high-severity risks, emphasizing the systemic failure to enforce air-gapping or zero-trust security models. The lapse not only jeopardized public safety but also invited state-sponsored or criminal exploitation, amplifying threats to national security. The company’s delayed mitigation efforts, coupled with regulatory gaps and legacy system dependencies, exacerbated the exposure, leaving critical infrastructure defenseless against attacks with life-threatening or war-escalating potential.

Incident : Exposure of Critical Infrastructure

Title: Mass Exposure of Industrial Control Systems to the Open Internet

Description: Nearly 200,000 industrial control systems (ICS), critical to power grids, water treatment plants, and manufacturing lines, are exposed to the open internet due to convenience-driven configurations, outdated security practices, and lack of safeguards. These systems, often running legacy software with unpatched vulnerabilities or default credentials, are vulnerable to cyberattacks that could trigger blackouts, chemical spills, or other catastrophic failures. The trend is accelerating due to digital transformation initiatives prioritizing operational efficiency over cybersecurity, with newly deployed systems in sectors like energy, transportation, and healthcare also appearing online without firewalls or encryption. Human error, misconfigurations, and regulatory gaps further exacerbate the issue, while experts advocate for asset inventories, patching, network segmentation, and AI-driven threat detection to mitigate risks.

What recommendations were made to prevent future incidents ?

Incident : Exposure of Critical Infrastructure JOH4502045100625

Recommendations: Conduct comprehensive inventories of all connected ICS/OT assets., Immediately patch known vulnerabilities, especially those with critical CVSS ratings., Implement network segmentation and zero-trust models to limit exposure., Enforce mandatory air-gapping for the most critical systems where feasible., Replace default credentials and enforce strong authentication mechanisms., Adopt continuous monitoring to detect and respond to exposures in real-time., Integrate AI-driven threat detection to identify anomalies and potential attacks., Prioritize cybersecurity training for IT and OT teams to address skill gaps., Strengthen regulatory frameworks with mandatory compliance and enforcement mechanisms., Foster a cultural shift to prioritize security over

Description

Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to versions 19.2.16, 20.3.14, and 21.0.1, there is a XSRF token leakage via protocol-relative URLs in angular HTTP clients. The vulnerability is a Credential Leak by App Logic that leads to the unauthorized disclosure of the Cross-Site Request Forgery (XSRF) token to an attacker-controlled domain. Angular's HttpClient has a built-in XSRF protection mechanism that works by checking if a request URL starts with a protocol (http:// or https://) to determine if it is cross-origin. If the URL starts with protocol-relative URL (//), it is incorrectly treated as a same-origin request, and the XSRF token is automatically added to the X-XSRF-TOKEN header. This issue has been patched in versions 19.2.16, 20.3.14, and 21.0.1. A workaround for this issue involves avoiding using protocol-relative URLs (URLs starting with //) in HttpClient requests. All backend communication URLs should be hardcoded as relative paths (starting with a single /) or fully qualified, trusted absolute URLs.

Description

Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. An Uncontrolled Recursion vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft deep ASN.1 structures that trigger unbounded recursive parsing. This leads to a Denial-of-Service (DoS) via stack exhaustion when parsing untrusted DER inputs. This issue has been patched in version 1.3.2.

Description

Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. An Integer Overflow vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft ASN.1 structures containing OIDs with oversized arcs. These arcs may be decoded as smaller, trusted OIDs due to 32-bit bitwise truncation, enabling the bypass of downstream OID-based security decisions. This issue has been patched in version 1.3.2.

Description

Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Prior to versions 7.0.13 and 8.0.2, working with large buffers in Lua scripts can lead to a stack overflow. Users of Lua rules and output scripts may be affected when working with large buffers. This includes a rule passing a large buffer to a Lua script. This issue has been patched in versions 7.0.13 and 8.0.2. A workaround for this issue involves disabling Lua rules and output scripts, or making sure limits, such as stream.depth.reassembly and HTTP response body limits (response-body-limit), are set to less than half the stack size.

Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. In versions from 8.0.0 to before 8.0.2, a NULL dereference can occur when the entropy keyword is used in conjunction with base64_data. This issue has been patched in version 8.0.2. A workaround involves disabling rules that use entropy in conjunction with base64_data.
