KIEV, Ukraine — The hacker, known only by his online alias “Profexer,” kept a low profile. He wrote computer code alone in an apartment and quietly sold his handiwork on the anonymous portion of the internet known as the Dark Web. Last winter, he suddenly went dark entirely.

Profexer’s posts, already accessible only to a small band of fellow hackers and cybercriminals looking for software tips, blinked out in January — just days after American intelligence agencies publicly identified a program he had written as one tool used in the hacking of the Democratic National Committee.

But while Profexer’s online persona vanished, a flesh-and-blood person has emerged: a fearful man who the Ukrainian police said turned himself in early this year, and has now become a witness for the F.B.I.

“I don’t know what will happen,” he wrote in one of his last messages posted on a restricted-access website before going to the police. “It won’t be pleasant. But I’m still alive.”
