Whether it's a sordid affair or a deeply private medical problem, everyone has some things they'd rather keep safely hidden from public view.

But experts now warn that artificial intelligence (AI) is poised to expose everyone's darkest secrets.

Cyber-security researchers say that AI's ability to connect the dots between tiny pieces of information could allow hackers to reveal even the most hidden details.

Even information that is years old could be at risk as hackers use AI to comb through decades-old data breaches for blackmail material.

Tech expert Kim Komando told the Daily Mail: 'If it exists in digital form, treat it like it could end up on a billboard.'

It comes as Meta becomes the latest tech firm to admit that a rogue AI escaped containment during testing and hacked into another company.

During a similar breach involving Anthropic models, researchers found that the AI had tried to trick people online by making fake accounts to send private messages.

So, as experts warn that AI is becoming a genuine cyber-security threat, here are all the ways it could be used against you.

Experts now warn that artificial intelligence (AI), such as OpenAI's ChatGPT, is poised to expose everyone's darkest secrets

Exposing affairs

Cheating spouses might go to great lengths to hide their infidelity, but those sneaky tactics are no match for hackers armed with AI tools.

Large-language models (LLMs), such as ChatGPT, are exceptionally good at combing through large volumes of data to find connections.

That means every credit card purchase, deleted message and location ping could become another breadcrumb leading back to an affair.

Connected devices such as smartphones, vehicles, and even smart doorbells are constantly gathering data about our movements and activities.

While one single piece of data might not be enough to out a cheater, AI tools can piece everything together into a single coherent picture.

'You'd need the discipline of a spy and the lifestyle of a hermit. Real people have neither,' says Ms Komando.

For hackers in search of blackmail material, AI tools are also offering powerful new abilities.

Tech experts say that AI could allow hackers to break into infidelity sites, such as Ashley Madison, and sift through millions of accounts to reveal cheaters' identities

In 2015, hackers cracked into the network of Ashley Madison, an infidelity dating service, and leaked the details of roughly 37 million users.

At the time, criminals or worried spouses had to manually sift through piles of data to find evidence, but now AI can do the same in seconds.

'Marriages ended. Careers ended,' Ms Komando said.

'That was more than a decade ago, before AI could sort through stolen data at superhuman speed.'

Exposing secret social media accounts

Whether you have a secret Instagram account to share photos with close friends or a throwaway Reddit account to rant about your boss, your anonymous social media presence might not be so hidden for much longer.

New research shows that the same LLMs that power ChatGPT and Claude have made it easy for hackers to identify anonymous accounts.

In most test scenarios, the AI was able to match the secret accounts with their public identities on other sites, based on information they post.

Researchers fed anonymous accounts into AI and asked it to scrape as much information as possible.

From simple details, such as mentioning having a dog that they walk in a certain park, the AI was able to find the real person with a high degree of confidence.

AI researcher Simon Lermen, who led the study, told the Daily Mail: 'AI agents can now browse the web like humans and perform similarly to a personal investigator, drafting a profile based on social media and everything that can be found online.

'Additionally, AI can attempt to identify pseudonymous accounts and information in breached datasets from previous hacks and incorporate that data.'

While the researchers only tested their tools on fictitious accounts made for the purpose of the trial, turning this technique on the public could be disastrous.

If you have a secret account where you share personal details you'd rather not be linked to, it's worth bearing in mind that those posts could soon come back to haunt you.

Hijacking smart home devices

AI tools aren't just letting hackers piece together more information; they are also helping criminals crack into once-secure systems.

Smart home systems, such as voice assistants, are gathering huge amounts of data to train AI models, which could be leaked by hackers

Equipped with even basic open-source tools, hackers are able to use LLMs' formidable abilities to find vulnerabilities in websites and devices.

At the top of criminals' target list are the AI-powered smart home devices that can be found in many homes - including security cameras that may capture your private moments.

Devices such as fridges, TVs, hoovers, and security systems have weak security systems that could be a backdoor to your sensitive data.

Konstantin Levinzon, co-founder of Planet VPN, says: 'Devices connected to homes often have weaker security than our smartphones or laptops, making them a more lucrative target for cybercriminals.

'Your TV, camera, or printer can open the door for cybercriminals to your network, and once they break in, it is hard to stop them.'

This is made worse by the fact that AI-powered devices in your home are now gathering vast amounts of data on you.

Dr Christopher Ramezan, assistant professor of cyber-security at West Virginia University, warns that these data-hungry systems pose a serious privacy risk.

Writing in The Conversation, Dr Ramezan says: 'AI tools, the companies in charge of them and the companies that have access to the data they collect can also be subject to cyberattacks and data breaches that can reveal sensitive personal information.

Experts say that devices like AI-powered hoovers could be an easy way into your network for hackers looking to steal personal information

'These attacks can be carried out by cybercriminals who are in it for the money, or by so-called advanced persistent threats which are typically nation/state- sponsored attackers.'

Leaking medical records

Another tempting target for AI-backed hacking tools is personal medical records.

Some cybercriminals will attempt to breach medical companies to hold personal details for ransom.

Mr Lermen points out that this information is typically held behind much stronger protections, but could be exposed by a hack.

Recently, thousands of medical records and patient information stored by Partnered Health, one of Australia's biggest healthcare providers, were stolen by hackers.

The company said that 21 clinics across several cities were affected by the breach, which leaked dates of birth, addresses and contact details as well as Medicare, private health insurance and concession card details.

Worryingly, AI is becoming significantly better at breaking into even the most advanced defences.

Cybersecurity experts have issued an urgent warning to Claude AI users after hundreds of private chats were found publicly available online

Mr Lermen says: 'We recently saw an incident where Claude Mythos attempted to insert malware into a piece of software.

'For this purpose, the AI unprompted researched the humans programming this software and then made an attempt to spearphish them - send them a customised message with a dangerous payload.

'Spear phishing is one type of social engineering that AI can either help with or perform autonomously.'

Likewise, if earlier hacks have dumped large quantities of medical data onto the internet, AI can help hackers find and search through these troves of material.

'Some of the danger of AI might simply come from searching the web for such information,' says Mr Lermen

Leaking private chats

However, having your secret information exposed online doesn't always require a malicious hacker.

AI chatbots themselves have proven to be exceptionally bad at holding onto their users' secrets, leaking private conversations and personal details straight to the internet.

Some leaked chats with AI are relatively harmless, like this conversation about birds, but others included revealing personal details

This month, users of Anthropic's Claude chatbot were horrified that their private conversations were accessible directly through Google.

The issue stemmed from the 'share' function, which allows users to make a hidden URL of their conversation to privately show to other users.

These URLs aren't meant to be visible on Google, but a technical error meant they could be found with a simple search.

Some chats exposed users' financial information, including the keys to one user's cryptocurrency 'wallet' – which would have allowed anyone online to empty their account.

Other chats revealed private or embarrassing information, such as elaborate erotic roleplays, while many could be traced directly back to the users' public profiles.

Likewise, in 2023, a bug exposed some ChatGPT users' personal information and credit card details to others using the service.

The issue caused a small number of users to see chats in their history that were not theirs, exposing huge amounts of personal information to total strangers.
