According to CoinMeta, researchers have discovered a serious security vulnerability that could put up to 70% of websites around the world at risk. This vulnerability may allow hackers to hijack unpatched servers, steal sensitive information, and launch attacks on website visitors. The flaw is widely used in various websites, including government portals and e-commerce sites. Both reports give the vulnerability a score of 9.2/10, which means attackers could potentially execute malicious code remotely without authentication. Recent developments include Finland shutting down its national internet services to address the security issue, the Dutch National Cybersecurity Agency taking down its websites, and France temporarily closing provincial websites for security repairs. Reports indicate that early attacks have already occurred, and protective measures have been implemented. Due to the leakage of vulnerability details, emergency patches were released ahead of schedule. EU cybersecurity officials are calling for immediate patching and advising operators to take down vulnerable websites if repairs cannot be made promptly. The biggest concern is that this vulnerability could accelerate the development of exploits, allowing hackers to weaponize them before millions of websites are protected.
