A recent advisory warns Microsoft users about malicious websites that install harmful applications on Windows PCs. Security researchers at DomainTools have identified a scheme where attackers create counterfeit websites resembling popular brands to trick users into downloading malware-laden applications. These applications deploy three types of malware: VenomRAT, StormKitty, and SilentTrinity, which can steal passwords and digital wallet information, and allow attackers to maintain control over compromised systems. The counterfeit sites impersonate well-known brands, including Bitdefender and various banks, highlighting the need for users to follow Microsoft's guidance on transitioning from passwords to passkeys. The attacks utilize open-source components, making them more efficient and adaptable. Users are advised to download software only from official websites, verify website addresses, and be cautious when entering credentials.
