One of my favorite parts of penetration testing is and always has been social engineering. I love it. In fact, I love it so much; I developed a real passion for it. My passion led well beyond the traditional social engineering and evolved into the study and practice of more sophisticated techniques associated with socio-psycho manipulation. It is a gift of sorts and who am I to question a gift? When speaking with prospective or current clients with respect to security assessments I have often implored them to include both physical security analysis and social engineering. This habit was formed upon entry into the world of professional security consulting where I sharpened these skills under the tutelage of many senior to me in both age and experience. Almost all of my earliest mentors in this space were or had been active in the United States DoD or like intelligence services, most of whom shared a common pedigree not unlike my own hailing from the world of information security and intelligence. These environments taught us to remain vigilant and open to idea that the unexpected should be expected therefore our ability to address anomalous events must remain categorically strong.
Over the years, within many engagements, activities of this nature were written into SoWs (Statements of Work for the lay person), and acted upon with full approval of parties both able to authorize such activity within and against their organizations and their legal representation (a detail I cannot stress enough that should not be overlooked). We would engage reconnaissance carefully leveraging skills we had cultivated in our former lives and applying them to the commercial world. We would engage in deep open source intelligence gathering and analysis in order to supplement our knowledge base regarding our target(s). We would become familiar with the physical environment in which our targets could and would likely be found. These locations would range from their places of business, to local restaurants and pubs, to local shopping districts to other geographic locales that we knew to be frequented by parties belonging to the organization, our target, in question. All the while we would be looking for ingress and egress points in addition to ideal areas for initial contact and exploitation. We would additionally identified areas in which useful information may or not be discarded by our targets that truly believed that no one would be interested (ah how I loved dumpster diving in my youth!). Finally, upon having enough information we would begin our careful insertion and infiltration. There is an art to doing this as much as there is a science and at times, the art becomes (or at least in my experience became), much more valuable.
These exercises almost always proved fruitful, as they would typically be multi-faceted involving multiple small teams each of which was cognizant of the others activities but all tasked with different missions during these exercises within the greater assessment. Some teams focused more upon the physical compromise of the environment, the acquisition of credentials and knowledge which could be socially engineered or stolen and thus counterfeited to serve our purposes in pushing deeper into the environment escalating our mission per our SoW and charter. Others would work on compromising individuals, seeking to gain their trust and subsequently their knowledge and any information considered noteworthy. Others still work on electronic and social engineering utilizing e-mail, web and telephonic techniques all designed to gain the trust of our targets or members of our target organizations in the hopes of escalating our privileges and advancing our efforts. This was good work. It was important work. And it was work that not all are capable of nor designed for. To the layperson reading this post I imagine it sounds outrageous if not frightening that work of this nature goes on and is conducted by security professionals in an effort to test and assess the security posture of a client and to a degree I can understand that attitude. However, this work is terribly important and often demonstrates weaknesses not previously accounted for within enterprise environments (public or private), during traditional security assessments and audits.
At this point you may be wondering whether or not there is merit in engaging a qualified team to do provide this type of service in addition to traditional services brought to the table as part of a security assessment. My personal perspective is that if you have overt responsible for the risk posture of an organization and understand that security or the state of being secure is contingent upon the three legs of the security stool (people, process and technology) being dutifully tested and exercised you most assuredly should do so. Failure to do so can expose you and your organization to a world of risk, which complying mindlessly with a three lettered data security standard or a mutagenic health-privacy act cannot hope to save you from. So what are we to do? First, if you haven’t already done so, conduct a meticulous review and analysis of your organizational information and physical security policies. If you don’t have any now is the time to remedy this deficiency. Should you (as I imagine most do, but will refrain from assuming), have these policies on hand review while employing a healthy dose of third party ego; remove yourself from the immediate, intimate involvement with them as they relate to your job and evaluate them as though you were brought in to do so as a third party. Do they look mature? Are they clearly articulated and well defined? Are they comprehensive? Do they address the natural bridges that occur between physical and logical security? Provided you have the resources, engage them to conduct preliminary assessments (provided they are qualified to do so), and if they are found to be lacking in the ability, do not hesitate to contact professionals with the appropriate pedigree, background and reputation to speak to about scoping a statement of work on your behalf. Remember that not every attack of a truly serious nature takes place across a wire and that many begin and end with a simple telephone call, a conversation around a smoking area or via a new hire.
