Who’s Really Behind That Executive Impersonator Requesting Your M&A Docs?

Why Executive Impersonation Keeps Working in 2025

Business e-mail compromise losses crossed $2.9 billion last year, and the most lucrative flavor is still “I’m the CEO, just do it.” The attacker’s OSINT path looks like this:

• • Scrape LinkedIn for the exec’s promotion history and writing cadence

• • Pull recent investor calls from YouTube to clone voice cadence

• • Register a cousin domain a week before the M&A announcement

• • Drop a burner phone number into the footer “just in case”

The good news: every one of those moves leaves footprints. Your job is to light those footprints up before the CFO hits “send.”

Five OSINT Checks You Can Run in Under Four Minutes

Here’s the field-tested checklist I keep taped inside my lab laptop lid for those panicked Slack calls:

Notice I didn’t list a single paid tool. Everything above is browser plus open-source plus the same sites your kids use to prank each other. Yet those four minutes have saved clients north of $30 million in the last eighteen months.

Kindi: Turning Your 4-Minute Check into 30 Seconds

I’m not a shill, but I’m also not stupid. When you’re staring at a potential $15 M loss, automation matters. Kindi lets me paste the suspicious email, auto-extracts domains, persons, phone numbers, runs the five checks above, and renders a link graph of who else interacted with those same indicators. The platform was born inside red-team exercises; now SOC analysts use it to prioritize alerts without needing a PhD in Python.

Real-World Walk-Through: The “Extra L” Domain

Last quarter a client pinged me about their “CEO” requesting W-2 copies. The sender domain looked perfect at first glance: acme-corp.com. Zoom in, though, and you’ll spot the extra “L” in “corp.” I fired up the playbook:

1. 1. Certificate transparency logs showed the domain got a TLS cert two days earlier.
   2. Passive DNS revealed only three IPs ever resolved to it, all cheap VPS hosts.
   3. Google dork “site:acme-corp.com” returned zero hits.
   4. LinkedIn showed the real CEO posted from an event in Chicago, but the mail IP geolocated to Sofia.
   5. Final nail: the phone footer matched a number created in Telegram six days prior.

Total time: two minutes, twenty-eight seconds. The CFO killed the thread, the CISO bought me a bottle of Yamazaki, and a crime that would have cost 1,200 employees their PII never happened.

Building Executive Impersonation OSINT into Consulting Engagements

Most consultants still treat business-email compromise as a user-awareness problem. That’s half the battle. Here’s how I fold executive impersonation OSINT into every M&A or cyber due-diligence engagement:

• • Pre-engagement recon: Map the exec digital footprint for clients and create a “canary” domain list so we catch cousin domains the day they’re born.

• • Table-top exercise: Run a live-fire phish using OSINT-derived language, then show executives how we caught it.

• • Continuous monitoring: Automate domain and cert alerts through Kindi and push findings to Slack or Jira.

Clients love the combo of offensive mindset plus defensive value. You’re not just the “pen-test guy” anymore; you’re the reason the CFO still has a job.

Advanced Tricks When the Adversary Gets Cute

Some crews register the cousin domain months in advance, let it sit, then weaponize it right after earnings. When passive DNS ages out, you need deeper artifacts:

• • Wayback crawl: Look for early placeholder pages or default server blunders.

• • Certificate overlap: Attackers reuse CAs; pivot on issuer hash to find sibling scams.

• • Crypto exchange tags: BTC wallets used for ransom often appear in underground forums; match against the email BTC address.

• • Voice-print deepfake score: Free tools like ElevenLabs’ detector provide a probability that the voicemail is synthetic.

Remember, the goal isn’t to write a dissertation; it’s to give general counsel a defensible “No, don’t pay” before market open.

Key Takeaways for Cybersecurity Consultants

If you leave with nothing else, tattoo this on your forearm:

1. 1. Executive impersonation OSINT is a race against the CFO’s trigger finger, not nation-state crypto.
   2. Four minutes of free-tool checks beats most $50 k appliances.
   3. Automate the boring parts with Kindi so you can focus on attacker logic, not wget syntax.
   4. Embed these checks into every due diligence statement of work; clients will pay extra for the peace of mind.
