MI5 has warned of espionage in which individuals are offered freelance geopolitical analysis work. I've seen these "cash for reports" ads on LinkedIn, posted by suspicious users offering high sums yet lacking the specificity that would give such reports actual value.

Despite the headline, this isn't limited to tech and it isn't limited to exec security. Corporate security spending is up across the board due to geopolitical/conflict risks, economic espionage, resilience requirements, and crisis management.

Another deeply frustrating article which reduces the extremely broad (and overwhelmingly ethical, legal, and frankly friendly) private intelligence field to a handful of dodgy private investigations and Due Diligence firms.

Tech theft isn't new: China's tea secrets were stolen by an East India Company spy and Venetian telescope makers were confined to the isle of Murano to prevent leaks. The (connected) modern economy and research collab makes the scale of today's challenge different though!

Everyone seems to think they have independently invented the corporate geopolitical risk field. CEOs have not left international relations to "lobbyists"; most have sophisticated political risk teams!

Essential reading from THE expert on the PDB!

#intelligence
In light of CNN’s recent reporting that the administration has cut back access to the President’s Daily Brief, I trace here the evolution of a dozen presidents’ choices about the PDB’s dissemination—a 60 year “who’s who” of intelligence-policy relations:

Donald Trump’s reported restriction of the President’s Daily Brief represents just the latest change in six decades of ebb and flow in the readership of this top secret, highly coveted document.
