Last week saw significant developments in cybersecurity, including Microsoft’s introduction of AI agents aimed at tackling phishing and data protection challenges. Google addressed a serious zero-day vulnerability in Chrome, while discussions arose around the limitations of cyber insurance. The UK’s National Cyber Security Centre provided guidance for domain registrars, and experts highlighted the hidden costs of security tool bloat. Other noteworthy updates included fixes for vulnerabilities in Firefox and CrushFTP, alongside insights on managing biometric data. ESET unveiled new threats from a China-linked hacking group, and cybersecurity job opportunities were also featured. Overall, the week shed light on ongoing security challenges and advancements in the industry.
Here’s a quick rundown of the latest cybersecurity news you might have missed last week, focusing on significant updates and insights for businesses and individuals alike.
In tech news, Microsoft has unveiled a new set of AI agents through its Security Copilot. These agents aim to tackle time-consuming security issues, such as phishing and data protection, making it easier for companies to manage their cybersecurity efforts.
Google recently patched a serious vulnerability in Chrome, identified as CVE-2025-2783. This zero-day flaw allowed hackers to bypass the browser’s sandbox security, prompting an urgent update for users on Windows.
Cyber insurance is another hot topic. Many companies assume their policies will cover them after a cyberattack. However, gaps in coverage and claim denials have raised concerns. It’s crucial for Chief Information Security Officers (CISOs) to carefully examine their policies and understand the risks involved.
In the UK, the National Cyber Security Centre (NCSC) has published new security guidance tailored for domain and DNS registrars. This resource aims to enhance the security posture of these essential services.
On the vulnerability front, CrushFTP has addressed a critical issue (CVE-2025-2825) that could let remote attackers exploit their enterprise file transfer solution. Companies using CrushFTP should apply the patch immediately to ensure their data remains secure.
Additionally, the emergence of Android financial threats has risen significantly, increasing by 20% in the latter half of 2024, according to ESET research. This highlights the growing need for businesses to safeguard their users’ financial information from evolving threats.
Lastly, as the use of large language models (LLMs) expands, security teams must be proactive about potential risks. A comprehensive approach to securing machine learning models is essential for organizations looking to leverage this technology effectively.
Staying informed about these developments can help businesses prepare better and secure their digital environments against potential threats.
