Spoiler: no sophisticated tool, accessible to any "ordinary" citizen
In 1944, the OSS (Office of Strategic Services), the forerunner to the CIA, produced the Simple Sabotage Field Manual. This document was declassified in 2008 - and is available on the CIA website.
Its goal was quite simple: train normal people, to subtly disrupt enemy operations without sophisticated tools or training.
In other words, teaching people to do their jobs in the worst yet subtle manner!
It’s a shortbook, written for historical wartime contexts… But, its relevance extends to understanding insider threats and organizational vulnerabilities today.
Without transition, let’s jump into a list of tactics from the declassified document !
Non-exhaustive list of some (very simple) tactics shared in this document
- Insist on strict adherence to bureaucratic processes.
- Prolong discussions with irrelevant issues, speeches, or debates.
- Refer decisions back to committees or demand excessive documentation.
- Demand written orders and delay delivering them.
- Assign inefficient workers to critical tasks.
- Over-inspect or reject perfectly acceptable work for minor flaws.
- Work slowly or inefficiently, creating unnecessary delays.
- Pretend not to understand instructions or deliberately make errors.
- Mix defective parts with functional ones.
- Delay, garble, or misroute messages.
