shadowmirror

Shadowmirror refers to a specific type of phishing attack that exploits the use of legitimate cloud-based services to store and distribute malicious content. Instead of hosting malware or phishing pages on compromised servers or dedicated malicious infrastructure, attackers leverage cloud storage platforms like Dropbox, Google Drive, or OneDrive. They create links to files or documents hosted on these services that, when opened, either download malware or redirect users to phishing websites designed to steal credentials.

The "shadow" in shadowmirror refers to the obscuring of the malicious activity by using trusted, well-known cloud providers. This makes it more difficult for traditional security defenses to detect and block, as the initial link points to a seemingly legitimate service. The "mirror" aspect refers to the fact that the attacker is essentially mirroring or duplicating malicious content onto a reputable platform. These attacks often rely on social engineering tactics within the initial communication, such as urgent requests or enticing offers, to trick users into clicking the links. The goal is to bypass security filters that might block direct links to known malicious domains.
