Security Research

1. Hacker Exploits Amazon Q AI Tool for Data-Erasing Attacks, Exposing Risks: A security researcher has uncovered vulnerabilities in Amazon's AI ecosystem, specifically targeting the Amazon Q AI tool. The exploit allows attackers to erase data, highlighting significant security risks within AI systems. This discovery has sparked discussions on social media platforms, emphasizing the need for enhanced security measures in AI technologies. Source: WebProNews.
2. AI Data Security: The 83% Compliance Gap Facing Pharmaceutical Companies: A recent study reveals a staggering 83% compliance gap in AI data security within the pharmaceutical industry. This gap poses a severe threat, as the leakage of sensitive data, such as molecule structures, could lead to significant financial losses. The report calls for urgent action to address these vulnerabilities and protect valuable research investments. Source: Clinical Leader.
3. Q2 2025 Ransomware Trends Analysis: Boom and Bust: The latest analysis of ransomware trends in Q2 2025 indicates a volatile landscape, with new affiliates potentially posing as security researchers or law enforcement. This trend complicates the identification of genuine threats and underscores the need for robust verification processes. The report suggests that organizations must remain vigilant and adapt to the evolving tactics of ransomware groups. Source: SecurityBrief Australia.
4. High-Severity Chrome Vulnerabilities Expose Users to Arbitrary Code Execution: Security researcher Shaheen Fazim has discovered critical vulnerabilities in Google Chrome, allowing for arbitrary code execution. These flaws, identified in July 2025, have prompted Google to issue urgent patches to protect users. The discovery highlights the ongoing need for vigilance and prompt response to security threats in widely-used software. Source: CyberPress.
5. Honeywell Smart Building Middleware Vulnerable: Security researchers have identified vulnerabilities in Honeywell's smart building middleware, which could potentially be exploited to bypass security alarms. This discovery raises concerns about the security of IoT devices and the need for manufacturers to implement stronger protective measures. The findings emphasize the importance of securing critical infrastructure against cyber threats. Source: BankInfoSecurity.

API Security

1. Possible ORM Leak Vulnerability in the Harbor: Administrator users on Harbor could exploit an ORM Leak vulnerability in the /api/v2.0/users endpoint to leak users' password hash and salt values. The vulnerability arises from the q URL parameter allowing filtering by any column, which can be abused to leak sensitive information. This flaw could potentially be exploited by lower privileged users to gain unauthorized access to sensitive data. Source: Vulners.
2. IBM Db2 Mirror for i Cross-Site WebSocket Hijacking: IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 are vulnerable to cross-site WebSocket hijacking. An unauthenticated malicious actor could exploit this by sending a specially crafted request to sniff an existing WebSocket connection, allowing them to perform unauthorized operations. Source: Vulners.
3. Digital Signature Forgery Attack on Bitcoin: A cryptographic attack known as Digital Signature Forgery Attack poses a threat to Bitcoin transactions by allowing attackers to create fake ECDSA digital signatures. This vulnerability risks unauthorized transaction authorization without the owner's private key, threatening the security of cryptocurrency wallets. Source: Vulners.
4. Stack-Based Buffer Overflow in u-link Management API: An unauthenticated remote attacker can exploit a stack-based buffer overflow in the u-link Management API to gain full access to the affected system. This vulnerability poses a significant risk as it allows attackers to execute arbitrary code remotely. Source: Vulners.
5. bun Vulnerable to OS Command Injection: All versions of the package bun are susceptible to OS Command Injection due to improper neutralization of user input in the $ shell API. Attackers can exploit this by providing crafted input with command-line arguments or shell metacharacters, leading to unintended command execution. Source: Vulners.
