It could definitely have been a "bump" (a manufactured 'accidental' introduction). If you work in a sensitive field, I'd definitely report it. If you hold a clearance, you should have already reported it.

I wouldn't spend much energy trying to second-guess who was ultimately behind the meeting. Especially if it is nefarious, often the initial contact is done with a cut-out or other intermediary and true affiliations are almost never disclosed initially (or perhaps ever).
