A Port St. Lucie man who brands himself online as a “Demonologist” and “Grey Hat Hacker” is back in the St. Lucie County Jail after being charged with illegally accessing women’s private information and posting it on TikTok.
Mark Stephen Asea, 36, was booked Sept. 30 on a felony charge of offense against computer users. His bond was set at $35,000, according to sheriff’s office records.
The case had been shut down once before. Asea was first arrested in April on stalking and computer-related allegations, but prosecutors dropped those charges in May. The case was reopened Sept. 24, and the new computer-access charge followed days later. Court records reviewed do not explain why the original charges were dropped or what led prosecutors to revive the case.
According to a police affidavit, two women told investigators their private information turned up in Asea’s TikTok videos. One woman said she had trusted him to help fix a computer problem.
A detective reviewing one of the videos documented Asea describing details about a woman’s devices and her recent online purchases.
“Let’s talk about your actual password,” he said, according to a transcript in the affidavit. “How about we talk about the last 10 purchases you made online?”
The woman said the password had only been shared in a closed TikTok group chat that Asea was not a member of, though she suspected he may have accessed it through a fake account. She told police no one in the chat had permission to share the password outside the group, and she did not know how he could have obtained her phone identification number or banking information.
The second woman said her trouble began after what she thought was routine tech support. She told police she let Asea remotely access her computer in October 2025 to troubleshoot an application. Months later, she said, he told her he had effectively planted a virus on her computer while she was out of the room, giving him access to her information without her knowledge or permission.
She said a photograph from a private Telegram message on her phone later appeared in one of Asea’s TikTok posts. He claimed in a comment that the image had come from WhatsApp, the affidavit states, but the woman gave investigators a screenshot showing the photo had actually come from Telegram.
Investigators also noted comments in which Asea appeared to claim he had tracked the woman’s location through her phone.
“Thanks to the GPS within her phone, but what did I do?” he said in one video, according to the affidavit.
Police said Asea posted more than 100 TikTok videos referencing one of the women, sometimes posting up to six in a single day, and that he also obtained a website where he posted a photo of her getting a tattoo.
Asea’s TikTok biography lists the terms “Demonologist,” “Clairsentient,” “Empath,” “PTSD,” “Grey Hat Hacker” and “Woodsman.” An earlier version of his account, documented in the April affidavit, described him as a “former satanist” and “cybersecurity engineer.”
Asea also faced a separate civil stalking case this summer. A woman was granted a temporary injunction against him in July, but a judge dissolved it and dismissed the case on Sept. 8.
Asea is scheduled to be arraigned on the felony computer-access charge Nov. 19.
