Anthropic's Claude Mythos is an advanced AI model currently available only to a select group of vetted technology companies, not the general public. While it holds significant promise as a defensive tool, capable of uncovering security flaws before criminals can exploit them, the same capabilities could be misused to lower the effort needed to exploit weaknesses in email, banking, and personal accounts.
For high-net-worth individuals, families, and executives managing significant assets, this increases the risk of targeted fraud, account takeovers, and financial loss, making strong cybersecurity practices more important than ever.
Claude Mythos is an advanced artificial intelligence model developed by Anthropic, the company behind the widely used Claude AI assistant. It can be thought of as a much more powerful version of AI tools that many people already use for daily tasks. Mythos goes far beyond earlier models, especially in areas such as complex reasoning, software analysis, and, most importantly, the ability to identify weaknesses in computer systems.
At this time, Mythos is not available to the general public. It is still going through testing and review and has only been released in a highly controlled way to a small number of trusted organizations. These include major technology and security companies such as Microsoft, Apple, Amazon, Cisco, and CrowdStrike. This limited release is intentional. Anthropic has stated that Mythos is powerful enough to cause serious harm if misused, so they have chosen to share it cautiously and with careful oversight.
There are two main reasons Mythos is receiving so much attention. The first is concern within the cybersecurity community. Mythos represents a major step forward in what AI can do when applied to computer systems. Security professionals worry that existing defense tools and practices have not yet caught up. There is also concern that criminals could use tools like Mythos to make cybercrime faster, cheaper, and easier to carry out.
The second reason is business momentum. Every major AI announcement attracts investors and increases public interest. This often raises the perceived value of companies such as Anthropic, OpenAI, and Google. As a result, Mythos has become not only a security issue, but also a financial and market-driven story.
It is important to understand that Mythos is not an isolated development. Other companies, including OpenAI and Google, have already released AI models with similar cybersecurity-related capabilities, though generally at a lower level. What makes Mythos different is how quickly and efficiently it operates, as well as Anthropic’s openness in discussing both its potential benefits and its risks.
Mythos does not create entirely new types of cyber threats. Instead, it significantly lowers the level of skill, knowledge, and time needed for attackers to exploit existing weaknesses. These weaknesses exist in the everyday technology we all rely on, including phones, laptops, email systems, and banking or investment applications.
Cyberattacks that once required a team of highly skilled hackers may soon be possible for a single individual using AI tools. For individuals and families with significant financial assets, sensitive personal communications, or access to influential networks, this increases risk. The most common and serious threats remain personal email compromise, fraudulent wire transfers, and targeted account takeovers.
Make sure all important accounts, such as banking, email, and investment platforms, use strong, unique passwords, and enable multi-factor authentication wherever it is available. In addition, use credit monitoring services to help detect fraud, unauthorized accounts, or identity misuse as early as possible.
AI can now generate very realistic phishing emails, texts, and phone messages. If something seems unusual or urgent, verify it through a separate and trusted method before taking action.
Organizations that manage your assets should be reviewing and strengthening their cybersecurity controls, including how sensitive data is protected and how fraud risks are managed.

AI-powered tools are now integrated into various platforms, from office software and operating systems to image editors and chat applications. But how can you use ChatGPT, Gemini, DeepSeek, and other AI-powered tools without compromising your digital security?
OpenAI’s privacy policy indicates that user data may be utilized to enhance AI performance. When using services like ChatGPT, Sora, or Operator, your interactions could be used to train AI models.
According to a study done by Harmonic Security, 8.5% of prompts contained sensitive information.
Never input sensitive personal information such as passwords, passport or banking details, addresses, phone numbers, names, or any confidential business data. If necessary, replace sensitive details with placeholders like asterisks or “REDACTED.”
For professionals, especially software engineers leveraging AI for code review, it’s crucial to strip out any information that could reveal company secrets and/or application structure.
Everything shared with an AI chatbot has the potential to be stored and analyzed.
Many free-tier AI tools explicitly state that they train on user data. Organizations using AI should consider investing in paid AI services like ChatGPT Enterprise, which ensures that user inputs and outputs are not utilized for training purposes.
Experts recommend paid plans as a more secure option for businesses looking to mitigate risks.
For businesses looking to integrate generative AI tools while minimizing security risks, Harmonic Security suggests shifting away from outright bans and instead implementing effective AI governance strategies. These include:

A family office exists to protect the family's wealth. Yet, the assets criminals are increasingly targeting with AI aren't corporate accounts or portfolios.
The targets are now personal phones, computers, social media profiles, and email addresses that belong to the people in the family themselves, as well as their trusted managers and executives.
Family office security must also extend there, because every one of those personal touchpoints is a potential doorway into everything else.
Criminals rarely stop at a hacked email inbox or a cloned social media profile. They use it as a foothold; a way to keep the cracked door open, ready for further entry.
This is what makes personal digital exposure so dangerous for family offices specifically: the assets being protected are already concentrated, and the family members connected to them are the easiest way in. Close one gap and criminals will look for the next unmonitored device, account, or email inbox.
Ultra-high-net-worth family office security solutions need to cover the full footprint of a wealthy family, not just the office itself.
Each of these, left unmonitored, becomes a route toward impersonation, extortion, or fraud aimed at the family and, by extension, the office itself.
Phones, tablets, and laptops used by principals, spouses, adult children, teenagers, grandparents and management staff are frequently the least protected devices in the entire family enterprise, even though they often hold access to email, banking apps, and shared documents.
Profiles tied to philanthropy, business involvement, or simply a family's public visibility are prime material for impersonation. A convincing fake account, built from real photos and real details, can be used to solicit money, extract information, or damage a family's reputation.
Home computers used for both family life and financial oversight are common malware entry points, particularly when shared across a household or used for both work and personal browsing.
A compromised personal or family email account is often the single most valuable asset to a criminal, since it's frequently the recovery method for banking, investment, and other financial accounts.
What has changed recently isn't just the number of points of exposure — it's how quickly and convincingly they can now be exploited:
That combination — minimal source material, minutes of setup, and near-flawless output — is what lets a single exposed asset be turned into an attack far faster, and against a far wider set of family members, than was possible even a few years ago.
Coverage in Canadian Family Offices has pointed to research from the law firm Dentons showing that many family offices have been slow to modernize their security practices, leaving them more exposed just as attacks are becoming easier to launch.
The greater danger isn't any one compromised account on its own — it's how several small exposures can be chained into a single, coordinated attack using AI.
A voice cloned from a public speech or interview can be combined with travel details or family updates pulled from a social media account to build a believable, time-pressured story. That story can then be delivered through a spoofed or already-compromised email address, adding a layer of apparent legitimacy that a bank, advisor, or household staff member may not question in the moment.
Recent reporting on Canadian fraud trends has described scammers using AI chatbots to sustain a fabricated interaction across multiple calls, emails, and messages, keeping a target engaged until money moves or information is disclosed.
The Canadian Anti-Fraud Centre has flagged impersonation and synthetic identity fraud, which similarly stitches together small pieces of real personal information into a convincing fake identity, among the fastest-growing fraud categories in Canada.
This is why closing every individual gap matters.
In an AI-assisted attack, an unmonitored device, an unclaimed and impersonated social media profile, and a leaked email password aren't isolated weaknesses — they're raw material an attacker can combine into one faster, more convincing, and more damaging campaign.
Closing these gaps means tightening the everyday habits around how a family uses its devices and accounts, alongside ongoing monitoring for signs of compromise:
Security for ultra-high-net-worth family offices means treating every family member's devices, accounts, and inboxes as part of the perimeter that needs protecting — not an afterthought outside it.
Richter Guardian monitors those personal assets on a 24/7 basis, watching for impersonation, malware, and leaked credentials before they turn into extortion or fraud, and helps families build the habits that keep new gaps from opening.
