From careless employees and departing executives to fake remote workers and hijacked AI assistants, the greatest danger to corporate information increasingly comes from someone who already has access. Rocky the Raptor here, RPost's Cybersecurity AI Product Evangelist, and this week, we're looking at a growing cybersecurity challenge: what happens when the threat doesn't need to break in because someone on the inside, knowingly or unknowingly, opens the door?
The $6.34 billion cryptocurrency heist at Binance began, remarkably, with something as ordinary as a job interview. According to Binance's November 3 incident report, a software engineer was approached about a potential new job. After an initial video interview and a second conversation with someone posing as a company's chief executive, the engineer was asked to download a coding assignment, which apparently contained malware.
The attackers eventually used compromised employee devices, stolen credentials, and an internal AI tool to reach Binance's wallet systems. On October 29, billions in digital assets were transferred. The FBI attributed the attack to North Korea's TraderTraitor operation. What makes the case so interesting is that the engineer wasn't accused of stealing the money. He had been tricked into opening the door.
This brings us to an important distinction: not every threat that originates from inside an organization is caused by a malicious insider. Sometimes it's a careless employee, a compromised account, a trusted third party, or an AI assistant acting on instructions it should never have followed.
This is not to say that the traditional insider threat has disappeared, but the boundaries of insider risk have expanded considerably. And sometimes the person gaining access isn't even who the company thinks it hired.
This is the oldest and most recognizable form of insider risk. An executive, engineer, or salesperson preparing to join a competitor quietly copies customer lists, pricing models, proprietary code, or strategic plans. The employee may rationalize the behavior as taking personal knowledge accumulated over years. The employer sees something different: intellectual property walking out the door.
This is a classic malicious insider scenario. The person has legitimate access and deliberately uses it for an unauthorized purpose. But not every damaging disclosure involves such intent.
A lawyer attaches the wrong confidential document, a finance executive selects an incorrect email address, or a business-development team sends acquisition details to the wrong party. The mistake in all these cases could take seconds. Once ordinary email and attachments have been delivered, conventional email recall is often unreliable or impossible. The damage can last years.
These employees aren't malicious insiders. They are authorized users making mistakes that can have consequences just as serious as deliberate data theft. This is why insider-risk management must address accidental disclosure, not just suspicious employee behavior.
An employee discovers that an AI summarization tool can analyze a 100-page strategic plan in seconds. In goes the document, and out comes a useful summary.
What the employee may not appreciate is that confidential information has now entered an external AI environment, potentially outside corporate governance, retention policies, or contractual protections. Whether it is retained, used for training, or exposed to others depends on the service and its settings. But once uploaded, the company may have little ability to retrieve every copy or reverse the disclosure.
The problem gets worse when the employee works for a supplier or professional adviser. Your organization may govern its own AI use, but not necessarily what happens to information legitimately shared with third parties.
Here, the risk doesn't necessarily originate from a bad employee or a compromised system. It comes from the expanding number of tools and external environments in which trusted people can handle sensitive information.
Modern phishing can capture more than passwords. An attacker may place a convincing imitation login experience between the employee and a legitimate service, capturing authentication-session tokens. This technique, commonly called adversary-in-the-middle phishing, can undermine conventional multifactor authentication. The employee thinks the login worked, but the attacker may now be able to access the account.
Strictly speaking, this isn't a malicious insider attack. It's an external attacker exploiting a trusted identity. But from the perspective of systems that recognize the employee's credentials or session, the activity may appear authorized.
That distinction matters. Organizations can spend heavily on preventing unauthorized access while remaining vulnerable when attackers successfully impersonate authorized users.
AI assistants can now read correspondence, summarize attachments, prepare responses, and perhaps send messages. But what happens when the assistant encounters an email containing hidden instructions intended for the AI rather than the human recipient?
This is prompt injection. A malicious message might tell the assistant to ignore its original task, extract information, or send data elsewhere. An agent with permission to act can become an unwitting accomplice. The risk depends on the agent's access and safeguards, but the attack requires no conventional malware.
This represents another expansion of insider risk. The AI assistant isn't an employee, and it doesn't have malicious intent. Yet it may operate with permissions granted by a legitimate employee, creating opportunities for attackers to misuse those privileges.
As organizations delegate more work to AI agents, protecting sensitive information increasingly means controlling not only what people can access, but also what their AI assistants can do with that access.
The FBI has warned repeatedly that North Korean operatives use stolen identities, fabricated résumés, and U.S.-based intermediaries to obtain remote technology jobs. Some have company-issued laptops hosted at American residences while the actual workers connect remotely from elsewhere. Once hired, they may access source code, sensitive systems, and intellectual property. Federal investigators have documented data theft, extortion, and schemes that finance North Korea's government.
Unlike the employee tricked into downloading malware, this scenario involves a malicious actor deliberately entering the organization under a false identity.
This is not the same technique used in the Binance engineer's fake interview, but both demonstrate how employment and recruitment processes have become cyberattack channels. One exploits the trust placed in a prospective employer. The other exploits the trust granted to someone who appears to be a legitimate employee.
Finally, consider the simplest workaround to sophisticated data-loss prevention software. An employee cannot download or forward a protected document, so the employee points a personal smartphone at the screen. The image can leave through a text message, personal cloud account, or messaging app, entirely outside the company's email controls.
Unlike accidental disclosure, this may be deliberate misuse of authorized access. And unlike phishing or account compromise, it requires no sophisticated technical attack.
Billions spent protecting digital files do little against an unrestricted camera.
These seven scenarios don't all qualify as traditional insider threats, and that is precisely the point. Some involve deliberate theft, others human error or compromised identities. Some exploit legitimate employees, while others involve malicious actors posing as employees or manipulating AI agents.
What unites them is the exposure of valuable information through an apparently authorized person, identity, or workflow. And this is where traditional approaches to insider-threat protection face a growing challenge. Preventing unauthorized access is important, but what happens when sensitive information is already in the hands of someone, or something, that has permission to use it?
This is where RPost's approach to PRE-Crime™ cybersecurity becomes relevant. Rather than focusing solely on detecting threats after the damage is done, the emphasis shifts toward recognizing suspicious activity early, limiting potential exposure, and maintaining control over sensitive information even after it leaves the organization.
For example, RPost's Double DLP™ capabilities help identify risky outbound communications before sensitive information reaches the wrong recipient. RDocs® extends that protection beyond delivery, allowing organizations to restrict or revoke access to supported protected documents. It also provides ways to discourage unauthorized sharing, including identifying information that can help attribute leaked content.
But accidental disclosure is only part of the problem. AI assistants, external collaboration tools, and third-party relationships are creating new opportunities for sensitive information to be exposed, often without malicious intent. RAPTOR™ AI and HawkEye™ 3D bring additional intelligence to these interactions, helping organizations recognize suspicious signals and potential risks that conventional security controls may overlook.
The counterintelligence dimension takes this further. By analyzing signals associated with access to protected content, RPost can help identify suspicious activity involving compromised insiders, third parties, or adversaries gathering information before an attack. When warranted, AI Auto-Lock™ can restrict further access to supported protected content.
The goal is not to assume every employee is a threat. It's to recognize that even legitimate access can become a security risk, and to give organizations a better chance of acting before that risk turns into a damaging incident.
For years, cybersecurity has focused heavily on keeping attackers out and responding when they get in. But today's insider-risk landscape demands another consideration: What happens to our sensitive information after someone is legitimately given access to it?
The next damaging incident may begin with an employee leaving for another job, attaching the wrong file, asking an AI assistant for help, or accepting what appears to be an attractive career opportunity. It may involve a criminal using a stolen identity, a trusted supplier mishandling information, or an AI agent following instructions hidden in an otherwise ordinary email.
The person involved might be malicious, careless, or simply fooled. In some cases, there may not even be a human insider directly responsible for the harmful action. The information at risk doesn't know the difference.
The future of insider-risk protection isn't merely about identifying the bad employee. It's about protecting the information, even when the employee is good, the identity appears legitimate, or the technology is trusted, but the decision or action is bad.
That is the PRE-Crime opportunity.
