How can organizations trust their AI when the data it learns from might be compromised?

Data poisoning is a growing concern in cybersecurity, especially with the expanding reliance on machine learning models. At its core, data poisoning involves malicious actors tampering with training datasets to undermine an AI system's performance or behavior. This manipulation could lead to subtle biases, complete dysfunction, or even harmful outcomes in critical applications like healthcare diagnostics, fraud detection, or autonomous systems.

For example, in a supervised learning model for financial fraud detection, attackers might inject fraudulent transaction data labeled as legitimate during the training process. As a result, the model becomes less effective at identifying real fraud cases. Detecting these poisoned inputs is immensely challenging, particularly in large-scale datasets where irregularities might appear statistically insignificant.

The threat becomes more pressing as organizations increasingly rely on third-party datasets or shared data repositories. Without stringent validation mechanisms, poisoned data can infiltrate and compromise AI at scale. Worse, attacks can be tailored—targeting specific outputs or patterns—allowing attackers to exploit vulnerabilities that are very difficult to predict or reverse.

Mitigating this risk requires advanced strategies. Techniques like data provenance checks, anomaly detection during data preprocessing, and model robustness testing can help. Also, employing federated learning (training models locally without centralizing data) limits exposure to malicious actors. But these defenses are resource-intensive and introduce their own complexities.

Ultimately, ensuring AI systems remain trustworthy hinges on securing the integrity of the data pipeline—not just reacting after the damage is done. As the adoption of AI accelerates, so does the urgency to prioritize its foundational safety.

Have you considered how "forgotten" data can still persist in AI systems?

Once shared, even for a moment, data can linger within generative AI chatbots like ChatGPT or Bard, potentially resurfacing in unexpected ways. Here's why: when you input information into these models, even if the original source is later deleted or access is restricted, the model may have already incorporated elements of that data during its training or refinement process.

This is particularly concerning because generative AI lacks traditional memory but learns by analyzing patterns in vast datasets. If sensitive details inadvertently become part of this learning, they can't easily be "unlearned." For example, if confidential company strategies are fed into a chatbot to draft a report, fragments of that data could indirectly reappear in future outputs.

Most providers try to manage this risk with clear limits on how inputs are used and improved privacy mechanisms. However, the challenge remains substantial. The lack of transparency over training datasets, combined with how models store relationships between words and ideas, makes control over such "forgotten" data complex.

Organizations and individuals must exercise caution by steering clear of sharing sensitive or private information with AI tools unless there's explicit assurance about privacy and data usage policies.

How secure is your information when you apply for a new job?

A Texas-based recruitment software company has disclosed that hackers managed to access sensitive data belonging to job applicants. Among the stolen information were Social Security Numbers (SSNs), financial details, and potentially other personal data provided during job applications. This breach raises serious concerns about the security of applicant tracking systems, which are widely used by companies to process hiring.

These systems often collect a significant amount of personal information, from resumes to tax documents, making them a prime target for cybercriminals. The breach highlights vulnerabilities in how sensitive data is stored and transmitted within such platforms. While details about the specific method of attack weren't disclosed, this serves as a reminder that encryption, regular audits, and robust cybersecurity protocols are essential when handling personal data.

For individuals, it’s critical to stay vigilant after such breaches. Monitoring credit reports, placing fraud alerts, and using identity theft protection services can reduce the potential harm caused by stolen financial or identification details. Companies, meanwhile, must reassess their cybersecurity strategies, ensuring compliance not just with basic security standards but with advanced, proactive measures to deter breaches like this in the future.

Did you know a single vulnerability could expose sensitive files and grant admin access to remote attackers?

Fortinet's FortiWLM (Wireless LAN Manager) recently faced a critical security flaw, tracked as CVE-2023-34990, with a CVSS score of 9.6. This vulnerability, now patched, allowed remote, unauthenticated attackers to exploit built-in log-reading functions via specific crafted requests. By leveraging this flaw, attackers could traverse directories, read sensitive files, and even hijack user sessions.

Here’s how it works: using the `/ems/cgi-bin/ezrf_lighttpd.cgi` endpoint, attackers could manipulate the `imagename` parameter to bypass input validation. This allowed unauthorized access to verbose logs containing static session ID tokens. Such tokens persist until the device reboots, enabling attackers to hijack sessions and gain admin privileges. Essentially, they could abuse log file access to control authenticated endpoints.

The issue affected FortiWLM versions 8.6.0 through 8.6.5 and 8.5.0 through 8.5.4 but has been addressed in updates 8.6.6 and 8.5.5, respectively. Security researchers also discovered that CVE-2023-34990 could be chained with another vulnerability, CVE-2023-48782 (CVSS 8.8), to enable remote arbitrary code execution with root-level permissions, significantly escalating the risk.

Although the exposure to the internet is relatively low—about 15 publicly visible instances—FortiWLM is especially popular among State, Local, and Education (SLED) sectors, as well as healthcare organizations. This pattern makes timely updates essential for those relying on these systems.

Keeping firmware updated and conducting regular vulnerability assessments are vital steps in defending against such threats, particularly when devices like Fortinet’s are frequent targets of cyberattacks.

How dangerous can a 9.5 CVSS vulnerability really be?

A critical flaw in Apache Struts, tracked as CVE-2024-53677, has caught the attention of threat actors. With a severity rating of 9.5 out of 10, this vulnerability could allow remote code execution (RCE) and poses a significant risk to organizations relying on Apache Struts for public-facing portals or internal workflows.

The flaw stems from improper handling of file upload parameters, potentially enabling an attacker to bypass restrictions, upload malicious files, and execute arbitrary commands. This could lead to data exfiltration, additional malware downloads, or even more advanced exploits. Struts versions between 2.0.0 and 6.3.0.2 are affected, but the latest patch in version 6.4.0 resolves the issue. Users running older versions are urged to update their systems immediately and adopt safer configurations using the new Action File Upload mechanism.

Interestingly, this vulnerability may be linked to an incomplete patch for last year’s CVE-2023-50164, which carried a slightly higher CVSS score of 9.8. Exploitation attempts for the latest flaw have already surfaced, with attackers scanning systems for vulnerable instances and uploaded scripts. For now, the origins of these attempts trace back to a specific IP address, but the situation is likely to escalate as proof-of-concept (PoC) exploits become more widely adopted.

Given Apache Struts' widespread use in high-stakes environments, unpatched systems expose businesses to significant operational risks. Immediate action is essential—update, reconfigure, and monitor traffic to detect any unusual activity.
