Crypto Exchange Impersonation SMS Scam for 02 5553 0253

Three contributors have reported SMS messages from 02 5553 0253 (also written as 0255530253) impersonating legitimate cryptocurrency exchanges. The scam targets users with text messages claiming to be from either CoinSpot or Coinbase, including fake withdrawal authorisation codes and urgent requests to call for support. All reports about 0255530253 describe the same social engineering pattern: a withdrawal code is provided in the SMS to create a false sense of urgency and legitimacy, followed by a callback request to this NSW-based number.

One contributor who received a call from 02 5553 0253 noted they don't even have a Coinbase account, indicating the attackers are sending these messages broadly without verifying whether targets actually use these services. The scam is particularly effective because it mimics the genuine security practices of real exchanges, which do send withdrawal codes and provide support numbers.

What Callers from 02 5553 0253 Say

The SMS messages impersonating 02 5553 0253 follow a consistent format designed to appear official. Contributors reported receiving texts stating "[CoinSpot] Your Withdrawal Code is..." or "[Coinbase] Your Withdrawal Code is [CODE]. Please do not share this code with anyone. If you have NOT requested this, please call: +61255530253 for support."

By using the exact branding and structure of legitimate exchanges, the messages are crafted to bypass initial skepticism. The inclusion of a specific numerical code adds credibility. One contributor described it as a code "to use to withdraw funds," with the implicit threat that someone else is attempting unauthorised access. This pressure tactic is designed to make recipients act quickly without verifying legitimacy, calling the number provided in the message.

Report Patterns and Timing

All three reports about 02 5553 0253 were submitted within a three-day window (16-18 November 2025), suggesting an active campaign targeting Australian users. Each report came via SMS, indicating attackers are using text-based phishing rather than voice calls. The scam affects both cryptocurrency platform users and non-users, with one contributor explicitly stating they have no Coinbase account, showing the attack is untargeted and broadly distributed.

The timing and similarity of reports indicate this is a coordinated effort, not isolated incidents. Contributors who received messages from 0255530253 all reported the same impersonation approach and callback mechanism, confirming this number is a known endpoint for this particular scam campaign.
