What Happened

In summer 2014, Medidata told its finance team to be ready to help with urgent transactions tied to a possible acquisition. On September 16, 2014, an accounts payable employee (Alicia Evans) received an email that appeared to come from Medidata's president, complete with his name, email address, and photo in the "From" field. It said an acquisition was near, that it was strictly confidential, and that an attorney named "Michael Meyer" would contact her. Meyer then phoned her demanding an urgent wire transfer. When Evans said she needed presidential authorization plus sign-off from a VP and the director of revenue, a follow-up group email, again appearing to come from the president, instructed all three to process and approve the payment. Evans entered the payee details Meyer supplied into Chase's online banking system, and the two executives approved it; $4,770,226 was wired to an overseas (Chinese) bank account. On September 18, "Meyer" requested a second transfer; the VP (Ho Chin) grew suspicious of the reply-to address, contacted the real president directly, and learned he had never made the requests. Medidata contacted the FBI and outside counsel. Investigators found the emails had been spoofed: an unknown actor embedded code so the messages displayed the president's identity while masking the true sender. Medidata disclosed the roughly $4.8M loss in a September 2014 SEC Form 8-K. This is a fully documented, real incident, confirmed by the company's own SEC filing and multiple federal court opinions.

How the Attack Worked

The scheme layered three pressures. First, authority and impersonation: emails were crafted so Medidata's Gmail-hosted system displayed the president's name, address, and photo, making them look genuinely internal. Second, a fake external "attorney" added legitimacy and a live, insistent human voice by phone, a classic BEC pattern of pairing a spoofed email with a corroborating caller. Third, secrecy and urgency: the "confidential acquisition" framing discouraged the employee from openly verifying, and the same-day timeline pressured fast action. Crucially, the attackers had context: finance staff had been pre-warned to expect urgent acquisition-related transfers, so the fraudulent request fit an expected pattern. When the employee's control (needing executive sign-off) kicked in, the fraudsters simply produced another spoofed "presidential" email to satisfy it, turning the internal check into part of the con.

The Lure & the Tell

Lure: a spoofed email appearing to be from the company president announcing a confidential, urgent acquisition and directing the employee to cooperate fully with an outside "attorney," reinforced by that attorney's phone call demanding a wire. Tells: the request bypassed normal process (wire demanded because a check would be "too slow"), leaned on secrecy to prevent verification, and originated from addresses that did not truly match the executive. The scam unraveled only when an executive independently examined a suspicious reply-to address and confirmed the request out-of-band with the real president, the single step that would have caught it earlier.

Outcome

The first $4.77M wire was lost; the second attempt was blocked after an executive's suspicion prompted out-of-band verification. Medidata filed an insurance claim under its $5M Chubb/Federal Insurance "Federal Executive Protection" crime policy; Federal denied coverage, arguing no hacking occurred and that employees transferred the funds voluntarily. Medidata sued (S.D.N.Y., 1:15-cv-00907). In July 2017 the district court granted summary judgment for Medidata under the policy's computer-fraud and funds-transfer-fraud provisions, awarding about $5.8M. The Second Circuit affirmed on July 6, 2018, holding the spoofing was a covered computer fraud and the proximate cause of the loss. No perpetrators were publicly identified or charged.

Why It Matters

This is a landmark early business email compromise (BEC) case and a foundational cyber-insurance precedent. It shows that no malware or system breach is needed: manipulating what recipients see in the "From" field, plus social pressure, is enough to move millions. It also crystallized a legal question that shaped how crime and cyber policies are written and litigated: whether "computer fraud" coverage extends to spoofing-driven wire fraud where employees themselves push the button. The court's answer ("larceny by trick is still larceny") helped establish that authorized-but-deceived transfers can still be covered fraud, influencing later BEC coverage disputes.

Defenses

Require out-of-band verification (a known phone number or in-person confirmation) for any wire transfer or change of payee, especially "urgent" or "confidential" executive requests; verification must be independent of the request channel. Treat secrecy demands that discourage checking as a red flag, not a reason to skip controls. Enforce dual-authorization that is genuinely independent (approvers should confirm with the executive directly, not rely on another email). Deploy email authentication (SPF, DKIM, DMARC) and external-sender/lookalike-domain warnings, and flag reply-to addresses that differ from the display sender. Pre-briefing finance staff to expect urgent transfers, as happened here, can backfire; pair any such heads-up with a mandatory verification protocol.

Attack Chain & Defense
The sequence the attacker ran
How it could have been stopped
1
Reconnaissance and target profiling: The court record shows the fraudsters knew Medidata's finance department had been told internally to expect urgent, confidential acquisition-related transfers, and knew the specific names, roles, and email-address format (first-initial-lastname@mdsol.com) of the president plus the accounts-payable clerk, the VP, and the director of revenue. This level of detail is consistent with, though not confirmed in the court opinions as arising from, typical OSINT against a public SEC-reporting company: corporate site, press releases, LinkedIn, and prior monitoring of email traffic patterns.
Countering Stage 1: Employee-facing OSINT exposure (names, roles, internal heads-up emails about upcoming deals) is very hard to eliminate at enterprise scale for a public company; the realistic control assumes attackers can gather this and hardens the payment process it later gets used against, at Stages 5 and 6, rather than trying to hide it.
2
Spoofing infrastructure and technique: The fraudsters crafted emails using code that exploited how Google's Gmail platform matched an incoming sender address to an internal contact profile, so forged messages displayed the real president's name, email address, and photo in the "From" field, per the district court's factual findings, a display-spoofing technique rather than a look-alike domain registration.
Countering Stage 2: Deploy and enforce SPF, DKIM, and DMARC, and configure mail platforms not to auto-populate a trusted contact's name and photo based solely on address-matching for externally originating mail; add clear external-sender banners so a message that looks internal cannot pass as such by display tricks alone.
3
Initial lure to a finance employee: A spoofed email, apparently from the president, told accounts-payable employee Alicia Evans that a confidential acquisition was imminent and that an outside attorney ("Michael Meyer") would be in touch, priming her to cooperate and to keep the matter quiet.
Countering Stage 3: Train staff, especially finance, that a request framed around secrecy or confidentiality is itself a reason to escalate and verify, not a reason to stay quiet; make "don't tell anyone" instructions in a financial request a mandatory trigger for manager or security review.
4
Live voice reinforcement: The fake attorney called Evans directly, demanded an urgent wire transfer, and dismissed a physical check as "too slow," a classic BEC pairing of a spoofed email with a corroborating live caller to add pressure and legitimacy.
Countering Stage 4: Treat any wire instruction delivered or reinforced by an unverified phone caller, especially a newly introduced outside party like an "attorney," as requiring an independent callback to a previously known number for that person or firm, never a number the caller supplies.
5
Defeating the internal control: When Evans said she needed presidential authorization plus sign-off from the VP and the director of revenue, the attackers produced a second spoofed group email, again appearing to be from the president, instructing all three to process and approve the payment, turning the intended safeguard into a step in the fraud.
Countering Stage 5: Make dual-authorization genuinely independent of the request channel: approvers should confirm directly with the purported requesting executive through a known-good channel (in person or a previously verified phone number), never by relying on a second email that could be forged the same way as the first.
6
Fraudulent transaction execution: Evans entered the attacker-supplied bank details into Chase's online banking system, and the VP and director of revenue, believing the instruction was genuine, logged in and approved the transfer through the same online system, completing the company's multi-approval process without anyone contacting the president directly.
Countering Stage 6: Require out-of-band, callback verification for any new or changed wire payee or bank details before funds move, applied as a standing rule rather than only after suspicion arises; this is the same class of check that ultimately caught the second attempted transfer here, just applied too late to stop the first.
7
Payout and objective completion: $4,770,226 was wired to a Chinese bank account on September 16, 2014. A follow-up request for a second wire two days later was stopped only when the VP noticed a suspicious reply-to address and verified out-of-band with the real president, confirming the fraud after the first payout had already succeeded.
Countering Stage 7: Once funds clear to an overseas account, recovery is largely outside the victim's control (none were recovered directly in this case); the practical fallback demonstrated here is carrying crime and cyber insurance with computer-fraud and funds-transfer-fraud coverage broad enough to respond, and being prepared to litigate a wrongful denial, which is what ultimately made Medidata whole.
