A recent incident involving a CEO with more than 20 years in cybersecurity is a useful reminder that account takeover can happen to anyone.
The executive reportedly had their account on X hijacked. The attacker changed the username, effectively disconnecting the account from its original handle, and then began sending messages on their behalf, some of which may have contained malicious links.
That small detail about the username is more important than it looks.
On X, the handle is a core part of identity. It is how people recognise and verify someone in practice. When an attacker changes it, the legitimate owner can temporarily lose control of that identity, and followers may not immediately realise something is wrong. In some cases, attackers may even attempt to reclaim or reuse the original handle, adding another layer of confusion.
This is not just an account takeover. It is an identity disruption combined with a trust attack.
Why a Trusted Account Is the Perfect Delivery Channel
A senior cybersecurity leader brings built-in credibility. Their audience includes peers, clients, and other trusted contacts. If that account sends a message, especially a short and casual one, people are far more likely to engage with it.
That is exactly what attackers are exploiting.
Instead of crafting long phishing emails, they rely on familiarity. A simple message like "can you check this?" or "have a look at this link" can be enough. Because it comes from a known and trusted source, the usual skepticism is lowered.
From there, the attack can move in different directions. The link might lead to a fake login page designed to steal credentials, or to a malware payload such as an information stealer or remote access tool. In some cases, it may be part of a broader campaign targeting multiple people within the same network.
What makes this effective is not technical sophistication, but context.
How These Accounts Get Compromised
As for how the account was compromised in the first place, the exact method is rarely confirmed publicly, but the likely paths are well understood.
Phishing remains the most common. Even experienced users can be caught by a convincing login page that looks identical to the real platform. Entering credentials once is enough.
Session hijacking is another possibility. Instead of stealing a password, attackers steal an active session token from a browser, which can allow access without triggering a fresh login, sometimes even bypassing multi-factor authentication.
Third-party app abuse is also a real risk. Over time, many accounts accumulate connected services. If one of those is malicious or becomes compromised, it can provide a backdoor into the account.
MFA fatigue is another technique that still works. Repeated authentication prompts are sent until one is approved, exploiting inattention rather than breaking security systems directly.
What stands out is that none of these methods require breaking advanced security systems. They rely on deception, timing, and normal user behaviour.
The Uncomfortable Part
Someone can have decades of cybersecurity experience and still be targeted successfully. Not because they lack knowledge, but because attackers are constantly refining how they exploit trust and attention.
This is why executive social accounts should be treated as part of the security surface. They are not just communication tools. They can influence perception, relationships, and decision-making across entire networks.
A compromised account at that level can be used to spread malware, impersonate leadership, or quietly target high-value individuals through direct messages.
What to Do About It
The takeaway is not about a single incident. It is about recognising a shift. Attackers are moving closer to people, not just systems. They are using real identities as delivery channels.
For those managing high-profile accounts, protections should go beyond basic setup. Strong multi-factor authentication, ideally hardware-based, careful control over connected apps, and visibility into login activity all matter. Just as important is having a clear recovery path if something goes wrong.
For everyone else, the mindset needs to change slightly.
Trust the person, but verify the message.
If a known contact suddenly changes username, sends an unexpected link, or communicates in a way that feels slightly off, it is worth pausing. A quick check through another channel can prevent a much larger problem.
