While many cybersecurity risks stem from external threats, the potential damage caused
by an attacker who has gained internal access—whether through a compromised user account,
physical access, or insider threat—can be far more severe. Barkrum’s Internal Penetration
Testing service simulates the tactics and techniques of a malicious actor operating from
within your organization’s network, revealing critical gaps in security controls that
traditional perimeter defenses often overlook.
Each engagement is led by a Barkrum Cybersecurity Specialist and follows a structured
methodology that combines automated scanning with advanced manual testing. We begin by
conducting a thorough discovery of the internal environment, including scanning all
accessible hosts for vulnerabilities such as outdated software, insecure configurations,
and exposed services. From there, our specialists execute a wide range of internal attack
techniques—ranging from basic credential harvesting to complex exploitation chains such as
LLMNR/NBT-NS poisoning, man-in-the-middle attacks, pass-the-hash, kerberoasting, and golden ticket attacks.
Upon completion of the engagement, Barkrum provides a detailed assessment report outlining every
discovered vulnerability, misconfiguration, and security gap, alongside their potential impact if
exploited by an internal threat actor. Each finding is rated by risk level, supported by technical
evidence, and accompanied by actionable remediation recommendations tailored to your environment.
