🔒🎮 Steam Enforces SMS Verification to Curb Malware-Ridden Updates

‍Valve, the company behind Steam, has announced new security measures to tackle the recent outbreak of malware-infected updates on the platform. Developers publishing games on Steam will now have to pass an SMS-based security check before releasing updates. This move comes in response to reports of compromised Steamworks accounts being used to distribute malicious builds that infect players with malware. Valve has assured the gaming community that the impact of these attacks was limited, but they are taking proactive steps to prevent future incidents. Starting from October 24, 2023, developers will need to associate a phone number with their Steamworks account to receive a confirmation code via SMS. The same requirement will apply when adding new users to the Steamworks partner group. Stay secure and enjoy gaming! 🎮

Emergence of BunnyLoader: A Versatile Malware-as-a-Service with Expanding Capabilities

‍In recent findings, cybersecurity experts have uncovered a novel malware-as-a-service (MaaS) known as 'BunnyLoader.' This malicious tool has been actively promoted across various hacker forums and is gaining notoriety for its fileless loader capabilities, allowing it to pilfer and substitute clipboard contents. However, BunnyLoader has evolved significantly since its initial appearance on September 4, now boasting a wide array of functionalities. These include the ability to download and execute malicious payloads, capture keystrokes, exfiltrate sensitive data and cryptocurrencies, and even carry out remote commands. Researchers at Zscaler have observed a rapid development cycle for BunnyLoader, with ongoing enhancements such as anti-detection mechanisms and additional data theft features. Notably, BunnyLoader's popularity is surging among cybercriminals due to its robust feature set, affordability, and user-friendly design, making it accessible even to those with limited hacking skills.

Microsoft AI Exposes 38TB of Confidential Data for 3 Years: A Lesson in Data Security

‍In a shocking incident, it was discovered that an overprovisioned SAS token exposed a massive 38-terabyte trove of private data on Microsoft's AI GitHub repository for almost three years. The token, which was misconfigured, granted unauthorized access to the entire cloud storage instead of the intended bucket. This exposed sensitive information, including secret keys, personal passwords, and over 30,000 internal Microsoft Teams messages from hundreds of employees.

The incident highlights the critical importance of robust data security measures. The researchers who discovered the exposure emphasize the risks associated with Account SAS tokens, which are long-lived and highly permissive, potentially escaping the monitoring perimeter. This breach could have facilitated a supply chain attack, enabling an attacker to inject malicious code into the storage blob, compromising users who relied on Microsoft's reputation.

Microsoft has been notified, and the SAS token has been invalidated. However, this incident serves as a reminder for organizations to implement stringent security protocols to safeguard sensitive data and regularly review and audit access controls to prevent unauthorized exposures.

Warning: Over 100,000 Critical Infrastructure Systems Exposed and Vulnerable

‍Cybersecurity experts at BitSight have issued a concerning alert, revealing that more than 100,000 critical infrastructure systems are currently exposed and susceptible on the internet. These systems encompass a wide range of vital components, including power grids, traffic light systems, security infrastructure, and water systems. Notably, this vulnerability extends to various devices like sensors, actuators, switches, building management systems, and automatic tank gauges.

Surprisingly, this figure represents an improvement from the previous year, highlighting a positive trend in addressing these issues since 2019. Vulnerabilities are widespread across essential sectors, including finance, education, and energy. Among the countries most at risk are the United States, Canada, Italy, the United Kingdom, and France. This alarming discovery underscores the urgent need for heightened security measures to safeguard critical infrastructure from potential cyber threats.
