He is basing much of his conclusion on the immense expenditure of time and resources needed to gather all of the information dumped. If it were hacked rather than simply stolen and disseminated from the inside.
As to the sex of the dumper, only a woman would seek to destroy the fantasies of a million men.
Or an idealistic techie who worked there, offended that the $19 being paid to delete information was just a huge scam.
Don’t automatically attribute the time/energy to a female involved. Most IT techs are aspies. Idealism and unrealistic views about interpersonal relationships are hallmarks of aspieness. Once they make up their minds about something...Could be found dad in the database. Or ‘the wife’.
Basing my supposition on the anger over $19 fees for anonymity being a scam as the modus operandi.
Firm I worked for about 20 years ago had a hack (inside hack) from someone interested in using the US web to look at porn. Used a very very circuitous way to get around internal safeguards. Took them weeks to set it up. To look at porn. That, in the European country from whence they hailed, was available over the television waves. And bypassed totally all the trading floors and ‘banking’ servers that had actual money on them to look at ‘nekkid women’. This was before streaming video was feasible btw, he was using the hackaround to look at still shots. And in his country there were public nude beaches and comely females there weren’t in short supply.
My assessment is based on the paucity of females with tech skills necessary, by and large.
