The present invention relates to a cybersecurity
system for preventing adversarial reconnaissance in cloud,
hybrid, and multi-cloud environments by dynamically modifying
user authentication identifiers, hostnames and fully qualified domain names. The
system updates login usernames in real time using randomized, non-repeating values generated from a configurable dictionary. Updates occur at scheduled, random, coordinated, or event-triggered intervals to disrupt profiling and targeting attempts. When identifiers are changed, associated sessions and tokens are invalidated to prevent reuse. The
system monitors expired credential usage to detect potential reconnaissance, generating alerts with intelligence such as IP addresses, timestamps, and affected resources. By eliminating predictable identity patterns, the system defends against reconnaissance-based attacks, unauthorized access attempts, and other credential-driven threats, thereby improving organizational security across cloud platforms.
