A vulnerability in Microsoft Defender, named ShieldBreak, has been revealed by security researcher Nightmare Eclipse, allowing malicious actors to gain complete system-level access to a user's device. Microsoft has previously warned against public disclosure of vulnerabilities and suggested potential legal repercussions for researchers who do so outside its protocols. Users of Microsoft Defender are advised to remain vigilant regarding this vulnerability.

A security researcher named Nightmare Eclipse has discovered a vulnerability in Windows, called ShieldBreak, which allows hackers to gain system-wide access to users' devices and sensitive data by exploiting a flaw in Windows Defender. The vulnerability affects Windows 10, Windows 11 (including version 25H2), and Windows Server 2025. A proof-of-concept exploit has been provided, requiring users to run a Windows application to trigger the vulnerability. Security researcher Will Dormann confirmed that Windows Defender must be enabled for the exploit to work. Microsoft has not yet released a patch for ShieldBreak, which is classified as a zero-day vulnerability. This discovery follows previous vulnerabilities disclosed by Nightmare Eclipse, including RoguePlanet, for which Microsoft issued an inadequate patch. The situation has heightened tensions between the researcher and Microsoft regarding the handling of bug reports, especially after Microsoft threatened legal action against researchers disclosing zero-days outside established protocols. The disclosure of ShieldBreak occurred shortly after Microsoft's monthly security patch releases, which have been increasing in number.

Security researchers from Huntress discovered a sophisticated SQL Injection (SQLi) attack that led to the deployment of a rare toolkit called Khunt. The attackers exploited a public-facing application backed by an Oracle database by failing to validate user input, allowing malicious SQL commands to be executed. The Khunt toolkit enabled activities such as executing operating system commands, stealing credentials, and exfiltrating registry hive data. Experts recommend robust defense mechanisms, including input sanitation, regular security audits, and the implementation of web application firewalls to protect against such attacks.

Recent research from the Electronic Frontier Foundation (EFF) has revealed that millions of Android users' location data are being inadvertently exposed to advertisers through third-party code libraries. This occurs when seemingly harmless applications, like weather services and fitness trackers, integrate third-party SDKs that collect user location information automatically upon permission approval, often without developers' awareness. Data brokers aggregate this location information to create detailed movement profiles sold to advertisers and government agencies. Despite privacy regulations like GDPR and CCPA, enforcement is inconsistent, and developers may claim ignorance regarding data practices they did not implement. Google has improved Android's privacy controls, but visibility into third-party libraries accessing data remains limited. Developers face challenges in auditing third-party code due to resource constraints, leading to a complex landscape where user information traverses multiple entities without clear accountability. Privacy advocates are calling for new technical standards to require SDKs to disclose their data practices.

The Microsoft Bounty Program awarded million to 562 researchers across 64 countries, surpassing last year's million distributed to 344 researchers. The program invites researchers to report vulnerabilities in Microsoft's products and services. This year's increase in submissions is partly due to advancements in artificial intelligence, which helps researchers identify vulnerabilities but also aids malicious actors. The Microsoft Zero Day Quest event resulted in over 700 vulnerability reports and more than .3 million awarded to participants.

Security researchers found that several Samsung Smart TV applications, including Pac-Man, were embedding residential proxy SDKs from data brokers like Bright Data. In response, Samsung has banned the inclusion of residential proxy functionality in new app submissions and is working to remove existing apps with such software. The investigation by Norwegian cybersecurity firm Mnemonic revealed that the Bright Data SDK was integrated into various gaming applications, some promoted by Samsung. While Samsung TVs were not automatically sharing internet connections, the SDK could be activated remotely by developers, requiring user consent. Once consent was granted, the proxy service could operate in the background. Many Samsung TV applications were found to download most of their code from remote servers, complicating verification processes. The issue of residential proxy software is not limited to Samsung, as it has also been identified in various Android apps and devices. Following these findings, LG and Google have also taken measures to address the risks associated with residential proxy networks.

Sergey Lozhkin, head of Kaspersky’s global research and analysis team for the Asia-Pacific, Middle East, Turkey, and Africa, reported an increase in malware injection attacks targeting AI agents, particularly from outside an organization’s network. He noted that traditional signature-based analysis is becoming ineffective as AI skills operate in the cloud, connecting to external resources. Dmitry Galov, leading Kaspersky’s research for Russia and the CIS, emphasized the importance of behavioral analysis and sandboxing AI applications to combat these threats. Lozhkin warned that the rapid growth of skills and plugins requires organizations to adopt innovative security measures, as old models are no longer sufficient.
