A new wave of crypto-related fraud surfaced over the New Year break, this time leveraging the Grubhub name to appear legitimate. Messages sent on December 29–30 instructed recipients to send Bitcoin to a specific wallet address, claiming the funds would be returned multiplied within a short time. Security experts say this type of “multiplier” offer is a long-running scam tactic.
How the Bitcoin Scam Was Detected?
The suspected scam drew attention after a series of unusual emails reached users and business partners on December 29 and 30. Framed as a holiday promotion, the messages pushed recipients to act quickly and transfer Bitcoin to a listed wallet address.
The emails used urgency cues such as “limited time” and “last chance,” aiming to trigger rushed decisions. Experts note that this pressure-driven approach is commonly used in crypto fraud schemes.
How the Grubhub Name Was Used?
The emails were designed to create the impression they originated from Grubhub, using branding elements and a tone similar to an official campaign announcement.
In some cases, the sender details appeared to resemble addresses associated with Grubhub’s partner communications, which can make the message look more credible at first glance. The campaign is believed to have targeted restaurants and other business partners in particular. Experts warn that any message requesting cryptocurrency transfers—even if it looks corporate—should be treated as high risk.
Did Grubhub Comment?
Grubhub confirmed that the messages in question were unauthorized. The company said it became aware of emails that appeared to be sent on its behalf and stated it is investigating the incident.
The company also stressed that the emails were not connected to any official Grubhub promotion, adding that steps were being taken to prevent similar attempts. Grubhub reiterated that it does not run campaigns that ask recipients to send cryptocurrency.
Why Experts Call It a “Classic” Bitcoin Scam?
Cybersecurity specialists describe “send Bitcoin and receive more back” offers as one of the most familiar online fraud patterns. The goal is to build quick trust, create urgency, and get victims to move funds before they pause to verify the claim.
Because cryptocurrency transfers are typically irreversible, scammers often favor this method. Experts also emphasize that reputable brands do not ask customers or partners to send crypto as part of a promotion—making such requests a strong red flag regardless of how convincing the email looks.
What Users Should Watch For?
Experts recommend verifying any promotion through official channels and treating crypto payment requests with extreme caution—especially during holiday periods when scams tend to spike.
Messages asking recipients to send cryptocurrency should be reported as phishing and deleted without engagement. Authorities and security professionals underline that “send–multiply–return” promises are a clear warning sign of fraud.
