Community reports for 02 9199 7881 (0291997881): Callers impersonate cyber crime units and Binance, requesting crypto account details and personal info via call and SMS.
Crypto Impersonation Reports for 02 9199 7881
Three contributors have reported scam activity from 02 9199 7881 (also written as 0291997881) involving impersonation of law enforcement and cryptocurrency exchange platforms. The reports describe callers claiming to be from a cyber crime unit and messages falsely attributed to Binance, all attempting to extract sensitive account information or redirect victims to fraudulent verification processes.
This Optus-allocated NSW number has been used in coordinated attempts across both voice calls and SMS to target cryptocurrency account holders. The pattern suggests sophisticated social engineering designed to exploit victims' trust in established institutions like law enforcement and major crypto platforms.
What Callers and Messages from 02 9199 7881 Claim
One contributor received a call from 02 9199 7881 where the caller claimed to represent a cyber crime unit and specifically asked questions about crypto accounts. The caller's authority impersonation was designed to pressure the recipient into disclosing sensitive financial information.
SMS messages attributed to 02 9199 7881 impersonated Binance, the major cryptocurrency exchange platform. The message included a verification code and explicitly warned the recipient not to share the code with anyone - a classic phishing tactic that creates urgency while mimicking legitimate platform communications.
A third report describes an SMS claiming a withdrawal request was pending and requesting the recipient call a hidden number to confirm the transaction. This callback request technique, combined with the fake withdrawal alert, attempts to manipulate victims into contacting scammers directly on attacker-controlled lines.
Report Patterns and Tactics
The reports show a multi-channel attack pattern across both voice and SMS. Two of the three reports involved impersonation tactics, while phishing links and callback requests appeared in separate incidents. The SMS reports mention verification codes and withdrawal alerts - language directly mimicking legitimate Binance communications to increase credibility.
One contributor noted they had experienced similar callback scams from different numbers weeks earlier, suggesting they may be on a targeted list. The coordination between impersonation (cyber crime unit, Binance) and technical social engineering (fake verification codes, hidden caller IDs) indicates organised scam activity rather than random spam.
