A major female star who has had thousands of intimate pictures and messages detailing her affair with a household name sportsman blocked the researcher who found them when he reported it to her.
The Daily Mail can reveal the woman, who is said to be British and in her 30s, had a two-year relationship with a top boxer who has won several titles, but they are now thought to have separated.
Cybersecurity expert Jeremiah Fowler came across the data leak online earlier this year and contacted both the woman, and her then businessman husband but both blocked him and refused to engage with him.
Jeremiah told the Daily Mail he also contacted the boxer concerned but received no reply.
He also informed police but it is not known if any action was taken and the material, which he described as 'very revealing' has now been removed.
The tech researcher discovered 86,859 images and messages from various Facebook, Whats App, Instagram and TikTok accounts belonging to the cheating couple.
Jeremiah described the woman as a 'high profile personality and entrepreneur' with millions of followers and who in turn was followed by other A listers with similar numbers of fans.
Jeremiah told the Daily Mail: 'I reached out to the woman and she blocked me immediately; she just didn't want to know what I had found was out there about her and what she was up to.
When an IT expert contacted a married British star to tell her that thousands of texts and explicit photos had been leaked online exposing her fling with a boxer, she blocked him
'It was all readily accessible, and my intentions were completely honourable, I had no desire to blackmail her or use the information I had found for criminal purposes, I just wanted her to know what I had seen.
'But she just wasn't interested, I found an account for her husband and discovered they were divorced so I messaged him and got a message back saying, 'She is no longer part of my life'.
'He said he wasn't interested either and also blocked me, so I then contacted the sports star but had no reply back and I also informed the police, but I don't think they took any action and the data has now gone.'
Jeremiah said he believed the sports star had managed to install spyware called Cocospy on the woman's phone to infiltrate her email and social media and it was programmed to take screen hots every few minutes.
Germany based Jeremiah, who is also a US national, said: 'I guess he thought if you are cheating on your husband I want to make sure you aren't doing the same to me.'
He added: 'I didn't want to scare the lady but I just thought she ought to know what was out there – it was real Jerry Springer stuff, toe curling and the sort of stuff you wouldn't want anyone else to read.
'From what I could see this was all material from 2024-2025 but the woman and her husband have now divorced.'
Cocospy was taken offline last year, along with two similar spyware apps, after a major security breach saw sensitive data leaked form millions of devices that were being monitored.
Jeremiah, who is a researcher for US based Black Hills Information Security, refused to name any of the people involved and added: 'I am an ethical researcher, so there is no way I can say the names, but I was surprised she didn't want to know.
'I was able to get hold of her and her ex-husband via the numbers that were on the screenshots and I told her that she was the victim of a crime because this software is illegal.
'Besides the messages there was also other highly sensitive information such as telephone numbers, emails, pictures of documents, invoices, receipts and a whole bunch of other stuff.
'It looks like whoever installed it set it up incorrectly and it therefore allowed anyone with an internet connection to access these sensitive images and messages.'
Jeremiah added:'This case highlights how easily personal communications and online interactions can be monitored when malicious software is present.
'My intention was to highlight these cybersecurity threats and provide guidance on how to identify and mitigate similar forms of digital surveillance.'
Cybersecurity expert Jeremiah Fowler said he contacted the woman to tell her about the leak, but she blocked him - and her husband was equally uninterested in engaging with him
Writing on ExpressVPN blog Jeremiah said: 'Stalkerware is a type of spyware that can be installed on a phone, tablet, or computer to secretly monitor another person's activities without their knowledge or consent.
'Once the software is installed, it can potentially track the victim's location, read messages, record calls, access photos, and monitor social media. Some types of spyware can even activate microphones or cameras.
'Stalkerware is often marketed as harmless monitoring or tracking, but in reality, it is commonly used in unauthorised surveillance.'
Despite the software attempting to go unnoticed, some signs may indicate that the device is infected with spyware.
These include unusual system behaviour, battery drain, higher than regular data usage, overheating, unexpected pop-ups, or unfamiliar apps mysteriously appearing.
In some cases, devices may run slower than usual, restart unexpectedly, or show strange permissions requests.
