Over 100 Ukrainian websites have been compromised by hackers who used fake Cloudflare checks to distribute a malware known as Lunex Stealer. This malware is designed to steal sensitive information, including browser passwords, authentication tokens, and cryptocurrency wallets from users. The attack targets individuals visiting these hacked sites, tricking them into downloading the malware under the guise of a security verification process. This incident is particularly concerning as it affects a wide range of users in Ukraine, potentially leading to significant financial losses and identity theft. The use of legitimate-looking fake checks makes it harder for users to recognize the threat, emphasizing the need for increased awareness and caution when browsing online.
