Is there still a lot of piracy with the goal to actually steal the goods though? My impression is that current-day pirates try to capture the ships themselves and hold them for ransom. (Genuinely curious though)

To be fair, historically, capturing people was likely always far more lucrative. The Mediterranean piracy for instance far was bigger (by several magnitudes) than the much more culturally popular Caribbean piracy.

The Barbary pirates enslaved about 1.25 million people between 1530 and 1780 (and it was a massive threat in the Middle Ages and ancient times we just don't really have reliable figures).

It was such a massive threat that coastal villages all but disappeared throughout much of Mediterranean Europe. The barbary pirates went as far as Ireland, England or even Iceland to murder an enslave people.

This was an issue up until the 1800s (the first foreign war the US fought was against Morocco and Tripolitania) when the European powers finally took a break from fighting each other to do something about their common enemies who were terrorizing their subjects for centuries.

I think so. I haven't read any recent news on it or anything, but there are surely still pirates that steal individual containers or sets of containers rather than trying to hijack the entire ship.

Individual containers are far far easier to steal dockside - seals can be broken and contents taken leaving the container and an undiscovered theft, containers can be rerouted onto trucks, etc.

Stealing a container on the high seas is damn near impossible, doable but a challenge.

The middle ground would be taking under tow floating containers that fall off of ships in bad weather - but I daresay that comes under salvage.

It's come down to hostage ransom now. Easier to pull some people off the boat and hide them in the jungle for ransom. The huge vessel they came in on requires expertise to crew.
