Vulnerability management is vital for cybersecurity but is limited to known assets, often leaving blind spots. External Attack Surface Management (EASM) enhances this by continuously identifying unknown risks and unmanaged resources. EASM provides real-time alerts and deeper visibility, enabling organizations to address potential threats effectively and secure their infrastructure.

A joint operation by the FBI, Europol, and cybersecurity firms has dismantled the Lumma Stealer malware network, responsible for over 10 million infections. The operation seized 2,300 domains linked to this malware-as-a-service, which targets sensitive data and employs advanced evasion techniques. Despite these actions, Lumma operators are expected to evolve further.
