Google has warned Android users about a significant zero-day exploit, identified as CVE-2024-53104, that could cause software instability and allow attackers to manipulate devices. This vulnerability operates at the Linux kernel level and affects all Android devices, including the Galaxy S25 and S24. A fix is included in the February security patch, but OEMs must distribute it. Current reports indicate that exploitation attempts are limited, but users are urged to update their devices promptly. Additionally, another flaw affecting Qualcomm technology may grant remote access to devices, with no reported victims yet. In 2023, 97 zero-day vulnerabilities were exploited, a 50% increase from 2022, primarily impacting Android devices.

The text discusses the increasing threat of cyberattacks due to reliance on digital devices without adequate protection, particularly antivirus software. It highlights the dangers of phishing and ransomware attacks, especially for businesses. Zero-day threats are described as vulnerabilities in software unknown to developers, which hackers exploit before a fix is available. Traditional antivirus systems primarily use signature-based detection and heuristic analysis, which are ineffective against zero-day exploits. To combat these threats, advanced strategies like Endpoint Detection and Response (EDR), artificial intelligence (AI), and Next-Generation Antivirus (NGAV) are being developed. A multi-layered security strategy is recommended, combining various tools and practices to enhance protection against cyber threats.

Researchers from the cybersecurity firm ESET discovered a zero-day exploit named "EvilVideo" targeting the Telegram messaging app on Android devices. The exploit, found on an underground forum, allowed attackers to send harmful payloads disguised as multimedia files by leveraging Telegram's automatic media download feature. Users could inadvertently download malicious files if they tapped the download button. Telegram released a patch in versions 10.14.5 and above to address the vulnerability by displaying malicious files as applications instead of videos. The exploit had a potential active window of about five weeks, but it remains unclear if it was used in the wild or the identity of the hacker behind it. The same forum account that promoted the exploit also advertised undetectable Android cryptomining malware.
