[[important update: It appears there is a critical error in my previous analysis. The email address returned by Constella for that 12 digit was actually sergio-gor@gmail.com, not sergio.gor@gmail.com (the latter being the address that registered steveking.com back in the day). Please accept my apologies for this horrible oversight on my part.]]

So I've been looking at this guy Sergio Gor, who's been described as one of the most powerful figures in the Trump administration: Director of the White House Office of Presidential Personnel.

Per The Times of Malta:

"While not the most glamourous sounding position, Gor’s role will see him wield considerable influence in the Trump government, responsible for vetting the appointment of thousands of employees.

Meanwhile, The New York Post wrote on June 17 that Gor still hasn't been vetted himself:

"...three administration insiders told The Post that the vetter-in-chief has not turned in his Standard Form 86, or SF-86 — a more than 100-page set of questions required for officials who need security clearances."

"Among the questions applicants must answer under threat of criminal penalties is where they were born and whether they have any foreign connections."

"Gor claims to be from the island country of Malta, though an official there could not confirm his birthplace when provided his exact birthday, saying: “No acts are registered with the provided details.”

"Gor declined to divulge his birthplace to The Post, other than to say it was not Russia."

His Wikipedia page says he was born in 1986 in Malta, and later moved w/ family to Los Angeles. But there indications he was born in Russia in 1980.

Sergio Gor is known to have worked on the campaign of the conservative former Rep. Steve King, and a search in Domaintools finds Sergio Gor registered Steveking.com way back when. Domaintools says Gor used the email address sergio.gor@gmail.com, which was also used to register the vanity domain sergiogor.com.

Constella Intelligence, a threat hunting platform that indexes breached data, finds this email address used the rather unique and long password: 961649507273. Constella further finds that this password is almost exclusively tied to a bunch of email accounts for the same name, including sgoryachev999@rambler.ru, goryachev-sergey@yandex.ru, sergio-gor@yandex.ru
sergio-gor@qip.ru, goryachev-sergey@ya.ru, goryachev-sergey@list.ru and goryachev-sergey@gmail.com.

Constella also says goryachev-sergey@yandex.ru has multiple entries in Russian government databases for a Sergey Anatolyevich Goryachev, DOB, Nov. 20, 1980, phone +79689210000. This person appears to have lived in Saratov, RU, has a tax ID number, etc.

Here's a mind map I put together on these findings. The password thing is very hard to get past.
