In 2023, two ethical hackers from Echelon Risk + Cyber, Kristopher Johnson and Michael, gained network administrator access to a client's system by exploiting a physical security flaw. They used social engineering tactics, offering to shovel snow during winter to bypass entry protocols, demonstrating how seemingly minor physical vulnerabilities can lead to significant cyber compromises.
Physical Security Breached by Snow Shoveling Red Team
A recent incident highlights the critical importance of physical security as a cornerstone of overall cybersecurity. In 2023, a professional red team successfully infiltrated a client's network by exploiting a simple oversight: an open maintenance door during a winter storm. This unconventional entry method underscores how human elements and environmental factors can create unexpected vulnerabilities for even well-defended organizations.
Echelon Risk + Cyber's Offensive Security Mission
The security assessment was conducted by Echelon Risk + Cyber, a cybersecurity professional services firm founded in 2021 and based in Pittsburgh, Pennsylvania, specializing in offensive security and compliance. Echelon Risk + Cyber provides tailored risk assessments and strategic security roadmaps to enhance organizational resilience. Kristopher Johnson, an offensive security consultant at the firm in 2023, led the on-site team, with his manager, Dahvid Schloss, providing remote supervision. Schloss, a recognized expert in offensive security with over 13 years in the industry, later co-founded Emulated Criminals.
Exploiting Human Trust and Winter Conditions
The red team's opportunity arose during winter conditions when a maintenance door at the client's office was left open. Johnson and another team member, Michael, entered through this unsecured access point, encountering a staff member in the mail room. Employing social engineering, they presented themselves as new IT employees whose badges were not yet active and offered to assist the maintenance crew with snow shoveling, a gesture readily accepted by the staff. While Michael helped clear snow, Johnson requested entry to set up Michael's laptop, gaining unchallenged access to the building's interior.

Once inside, Johnson was free to explore the premises, seeking a suitable location to deploy a Raspberry Pi, a small, credit-card-sized single-board computer often used in penetration testing due to its portability and affordability. This device would allow for persistent access to the network, bypassing traditional perimeter defenses. This incident vividly demonstrates how physical breaches can directly lead to significant cyber compromises, highlighting a critical, yet often overlooked, attack vector.
What This Means
This incident serves as a stark reminder that even advanced digital defenses can be rendered ineffective by fundamental lapses in physical security. Organizations frequently invest heavily in firewalls, intrusion detection systems, and encryption, yet overlook the human element and physical access points. A robust cybersecurity posture requires a holistic approach that integrates strong physical controls, employee security awareness training, and regular red teaming exercises. Without addressing these physical vulnerabilities, companies remain susceptible to determined attackers who understand that the path of least resistance often lies outside the digital realm. The ease with which a Raspberry Pi can be deployed for network penetration testing further emphasizes the need for vigilance.
Key Points
- Professional red teamers exploited a physical security flaw in 2023 to gain network access.
- The team used social engineering, offering to shovel snow, to bypass entry controls.
- Kristopher Johnson and Michael, from Echelon Risk + Cyber, conducted the assessment.
- Dahvid Schloss, a seasoned offensive security expert, supervised the operation remotely.
- A Raspberry Pi was intended for deployment to establish persistent network access.
The Bottom Line
The snow-shoveling red team incident underscores that physical security is not a separate concern from cybersecurity; it is an integral part. Businesses must implement comprehensive physical access controls, conduct regular employee training on social engineering awareness, and perform realistic physical penetration tests to identify and remediate vulnerabilities. Neglecting the physical perimeter leaves an open door for threat actors, regardless of the strength of digital defenses. Organizations should continuously evaluate their security posture, recognizing that human trust, when exploited, can be the weakest link in any defense strategy.
