According to Aqua Security researchers, attackers could exploit flaws in the vulnerability disclosure process of open-source projects to gather the information they need to launch attacks before patches are made available. The maintainer is aware of "half-day" vulnerabilities, and information about them is publicly available on GitHub or the National Vulnerability Database, but there is still no official fix.

The attorney general of the state of New York recently announced that a medical company has been fined $450,000 over a data breach resulting from a ransomware attack.  According to the New York AG's office, US Radiology Specialists, a major private radiology group, was targeted in a ransomware attack in December 2021.  The incident resulted in the personal and health information of nearly 200,000 patients, including 92,000 New Yorkers, getting compromised.

Jen Easterly, Director of the Cybersecurity and Infrastructure Security Agency (CISA), and Baek Jong-wook, the Republic of Korea's Deputy Director of the National Intelligence Service (NIS), have signed a Memorandum of Understanding (MoU) outlining collaboration areas under the bilateral Cyber Framework signed by President Biden and Republic of Korea President Yoon in April. The Cyber Framework declares cooperation with Korea in CISA mission areas, including sharing technical and operational cyber threat information and best practices in cyber crisis management.

The National Security Agency (NSA), the Office of the Director of National Intelligence (ODNI), the Cybersecurity and Infrastructure Security Agency (CISA), and industry partners have published "Securing the Software Supply Chain: Recommended Practices for Software Bill of Materials Consumption." This Cybersecurity Technical Report (CTR) aims to help software developers, suppliers, and customer stakeholders ensure the integrity and security of software through contractual agreements, software updates, notifications, and vulnerability mitigations.

The US Cybersecurity and Infrastructure Security Agency (CISA) has added the Service Location Protocol (SLP) vulnerability, tracked as CVE-2023-29552 with a CVSS score of 7.5, to its Known Exploited Vulnerabilities (KEV) catalog. The SLP is a legacy service discovery protocol that enables computers and other devices to find services in a local area network without initial configuration. The flaw is a Denial-of-Service (DoS) vulnerability that an unauthenticated, remote attacker can exploit to register arbitrary services.

Russia's Sandworm Advanced Persistent Threat (APT) group used Living-off-the-Land (LotL) techniques to cause a power outage in a Ukrainian city during missile strikes in October last year. Sandworm, which is linked to Russia's Main Center for Special Technologies, has a long history of cyberattacks in Ukraine, including the 2015 and 2016 BlackEnergy-induced blackouts, the NotPetya wiper, and more recent campaigns that overlap with the Ukraine war. This article continues to discuss the Sandworm APT's disruption of power in Ukraine.

A new set of malicious Python packages has infiltrated the Python Package Index (PyPI) repository, aiming to steal sensitive information from compromised developer systems. According to Checkmarx, the packages appear harmless obfuscation tools, but they contain malware called BlazeStealer. The malware retrieves an additional malicious script from an external source, enabling a Discord bot that gives attackers control over the victim's computer.

OpenAI has confirmed that ChatGPT and its API experienced a major outage on Wednesday due to what appeared to be a distributed denial-of-service (DDoS) attack.  The organization reported seeing problems with its LLM-based chatbot and API on November 7.  The disruptions were initially described as partial outages, but a major outage was reported on November 8.

Japanese electronics manufacturer Japan Aviation Electronics is recovering from a cyberattack for which the Alphv/BlackCat ransomware group has claimed responsibility.  The company was founded in 1953 and headquartered in Shibuya, Tokyo.  Japan Aviation Electronics manufactures electrical connectors, aerospace electronics, and user interface related devices.  The company noted that the incident occurred on November 2 and involved some of its servers being accessed by an unauthorized external party.

Researchers at the University of North Dakota (UND) will use an award from the US Department of Energy (DOE) to develop algorithms for a cybersecurity software tool that will help Distributed Energy Resources (DERs) securely participate in energy markets. Examples of DERs include solar and wind power generation methods and devices such as electric vehicle chargers. As these devices, which are typically connected to the Internet, are increasingly being added to power grids across the US, additional cybersecurity measures are required.
