AI Model Identifies Multiple Security Vulnerabilities in Firefox

-


 Artificial intelligence is increasingly being used in cybersecurity research, and a recent collaboration between Anthropic and Mozilla demonstrates its potential. During this initiative, Anthropic’s advanced AI model was used to analyze the source code of the Firefox browser and successfully detected 22 previously unknown vulnerabilities.

Among the discovered issues, 14 were categorized as high-severity vulnerabilities, meaning they could potentially have serious security implications if exploited by attackers. Mozilla addressed the majority of these security flaws in a recent browser update, which was released to strengthen Firefox’s overall security.

AI-Driven Vulnerability Analysis

The AI model analyzed a large portion of Firefox’s codebase in order to identify patterns that could indicate potential weaknesses. By examining thousands of lines of code, the system was able to detect unusual behaviors and potential memory-related errors that might lead to security problems.

One of the most notable discoveries occurred early in the analysis, when the system identified a memory management issue within the browser’s JavaScript engine. After the finding was reported, security researchers reviewed the issue and confirmed that it represented a real vulnerability that required remediation.

Throughout the research process, the AI generated numerous reports highlighting potential issues within the code. However, after verification by human researchers, only a portion of those reports were confirmed to be legitimate security vulnerabilities.

Evaluating AI’s Ability to Create Exploits

Researchers also wanted to understand whether the AI could go beyond simply identifying vulnerabilities and actually develop working exploits. To test this capability, the system was tasked with attempting to convert some of the identified vulnerabilities into functional exploits.

Despite multiple attempts and extensive computational resources, the AI was able to produce a working exploit only in a limited number of cases. This suggests that while AI can significantly accelerate vulnerability discovery, creating reliable exploits remains a much more complex process.

Impact on the Future of Security Research

The results highlight the growing role of artificial intelligence in software security testing. AI systems are capable of analyzing large codebases far more quickly than traditional manual approaches, which may help security researchers identify vulnerabilities earlier in the development process.

At the same time, the increasing use of AI for vulnerability discovery could create new challenges for software developers, as automated systems may generate a large number of potential security findings that require careful verification and remediation.

The Hidden Lag Killing Your SIEM Efficiency

-

  If your security tools feel slower than they should, you’re not imagining it. Many IT teams blame their sluggish SIEM performance on query complexity or alert volume. But sometimes the real issue is much simpler: oversized input files quietly dragging your system down. Think about the last time you had to sift through a bloated PDF or an unoptimised log dump. Every unnecessary megabyte adds strain. Every redundant line eats up cycles. Your SIEM doesn’t just react to threats—it processes all incoming data, relevant or not. When it starts lagging, detection gets delayed, triage slows, and in the high-stakes world of threat response, even seconds count. We often focus on analytics and rule tuning, but upstream efficiency—what you feed into your system—deserves just as much attention. This article looks at how optimising your inputs unlocks downstream performance. Why Oversized Files Clog the Pipeline As data volumes grow, organisations face esca lating  data storage costs ,...

Critical Vulnerability in Veeam Backup & Replication Exposes Enterprises to Remote Code Execution By : Rei Ibraima A newly discovered critical vulnerability in Veeam’s Backup & Replication software, designated as CVE-2025-23120, poses a significant security risk to enterprise environments. The flaw allows authenticated domain users to execute arbitrary code remotely, potentially leading to full compromise of backup infrastructures. About CVE-2025-23120 The vulnerability arises from an insecure deserialization issue within Veeam Backup & Replication components—particularly in the .NET classes Veeam.Backup.EsxManager.xmlFrameworkDs and Veeam.Backup.Core.BackupSummary. Improper input validation in these components allows attackers to inject malicious serialized objects that are executed on the server side, resulting in Remote Code Execution (RCE). This issue affects systems where Veeam Backup & Replication is deployed in a domain-joined configuration, which—while common—is...

Lotus Panda Hacks SE Asian Governments With Browser Stealers and Sideloaded Malware

The China-linked cyber espionage group tracked as Lotus Panda has been attributed to a campaign that compromised multiple organizations in an unnamed Southeast Asian country between August 2024 and February 2025. "Targets included a government ministry, an air traffic control organization, a telecoms operator, and a construction company," the Symantec Threat Hunter Team said in a new report shared with The Hacker News. "The attacks involved the use of multiple new custom tools, including loaders, credential stealers, and a reverse SSH tool." The intrusion set is also said to have targeted a news agency located in another country in Southeast Asia and an air freight organization located in another neighboring country. The threat cluster, per Broadcom's cybersecurity division, is assessed to be a continuation of a campaign that was disclosed by the company in December 2024 as a high-profile organization in Southeast Asia since at least October 2023. ...
