It's possible that the first woman was using a fake name to drop the tip without involving herself. Since then, there's been at least one other person come forward. She's actually spoken with the Atlantic and her story
corroborates the first one.

But she’s not the only woman who’s come forward: Jennifer Taub, a professor at Vermont Law School, received an email from a man using a Surefire Intelligence email address around the same time, on October 22. “It’s my understanding that you may have had some past encounters with Robert Mueller,” he told Taub, according to the email she forwarded to me on Tuesday afternoon. “I would like to discuss those encounters with you.” (Taub told me she has never had any encounters with Mueller, though she does appear on CNN at times as an expert commentator on the Mueller probe.)
“I believe a basic telephone call, for which I would compensate you at whatever rate you see fit (inside reason), would be a good place to start,” the man continued. “My organization is conducting an examination of Robert Mueller’s past. Tell me a decent method to contact you by telephone (or Signal, which would be ideal) and a beginning rate to talk with you about all encounters you’ve had with Special Counsel Mueller. We would likewise pay you for any references that you may have. Lastly, I would appreciate your discretion here, as this is a very sensitive matter.” Taub told me she forwarded the email to the special counsel’s office, noting that she did not plan to respond.
