<p>International relations might have been polite at summit meetings this week in Asia, but in cybersecurity, the global struggles proceeded as expected. Driving much of the news were tales of nation-state threat groups causing damage worldwide through breaches, <a href=”https://www.techtarget.com/whatis/feature/Common-cryptocurrency-scams”>cryptocurrency crimes</a>, hacktivism and tampering with critical infrastructure.</p>
<p>China, Russia, Iran and North Korea often play key roles in nation-state attacks targeting Western governments and businesses. Cybersecurity vendor Trellix <a target=”_blank” href=”https://www.cybersecuritydive.com/news/north-korea-hacking-trellix-report/803641/” rel=”noopener”>attributed</a> North Korean groups with 18% of the nation-state activity it detected between April and September, the largest share of such schemes.</p>
<p>This week’s featured articles examine nation-state threats that have affected a range of targets, from a company’s revenue forecasts to industrial control systems (ICSes) in Canada.</p>

<h2 class=”section-title”><i class=”icon” data-icon=”1″></i>Nation-state cyberattack hits F5’s top line</h2>
<p>Network technology vendor F5 said this week that some of its customers are hesitant to sign or renew contracts following an intrusion by a nation-state group, which was subsequently <a href=”https://www.bloomberg.com/news/articles/2025-10-16/potentially-catastrophic-breach-of-cyber-firm-blamed-on-china”>reported to be China</a>. After <a href=”https://www.cybersecuritydive.com/news/f5-supply-chain-breach-nation-state-cisa/802887/”>breaching the company’s networks</a>, the group maintained long-term access to F5’s development and engineering platforms. The hackers accessed information about security vulnerabilities that F5 was evaluating.</p>
<p>Given the visibility of the incident, some F5 customers are holding off on new commitments, CEO François Locoh-Donou told investors during an earnings call Monday. F5 said it expected revenue growth in fiscal 2026 to be anywhere from flat to 4%, which would fall short of the roughly 9% growth predicted by Wall Street.</p>
