Link: Bleeping Computer
T-Mobile has agreed to pay a $315 million settlement to the FCC following four major data breaches that exposed the personal information of millions of customers. The settlement covers fines for the inadequate security measures that allowed the breaches to occur, as well as funds to improve T-Mobile's cybersecurity infrastructure.
Windows Event Logs Targeted by Ransomware
Link: Cybersecurity News
Ransomware attackers are increasingly targeting Windows Event Logs as part of their strategy to cover their tracks. By manipulating or erasing event logs, attackers can make it more difficult for forensic teams to identify the origin and scope of the attack. This tactic is gaining popularity among ransomware groups looking to hinder incident response efforts, making it crucial for organizations to implement advanced logging and monitoring solutions.
Critical Flaw in NVIDIA Toolkit Allows Full Host Takeover
Link: Bleeping Computer
A critical vulnerability in NVIDIA's container toolkit has been discovered, allowing attackers to gain full control over host machines. This flaw affects systems that use the NVIDIA toolkit for containerized applications, commonly found in environments leveraging AI and machine learning technologies. By exploiting this vulnerability, attackers can escalate privileges and execute arbitrary commands on the host machine. Organizations using the toolkit should apply patches immediately to prevent unauthorized access.
Shadow AI Increases Workplace Sensitive Data Exposure
Link: Dark Reading
The growing use of unregulated AI tools in the workplace is leading to an increase in sensitive data exposure. Employees using AI-powered chatbots without proper oversight are unknowingly sharing confidential information, which can be exploited by cybercriminals. Known as "Shadow AI," organizations should implement stringent policies around the use of AI technologies to mitigate the risk of data leakage.
Critical Ivanti VTM Auth Bypass Bug Now Exploited in Attacks
Link: Bleeping Computer
A critical authentication bypass vulnerability in Ivanti's Virtual Traffic Manager (VTM) software is being actively exploited in the wild. Attackers can use this flaw to bypass security controls and gain unauthorized access to sensitive data. Organizations using Ivanti VTM are advised to patch their systems immediately to prevent exploitation and mitigate potential risks to their networks.
