Internet Security Impersonation Reports for 02 7245 4557
Four contributors have reported calls from 02 7245 4557 (also written as 0272454557) involving deceptive claims about internet security. The pattern centres on callers impersonating technical support or government representatives, attempting to create urgency about alleged security breaches that do not exist.

The caller behaviour suggests a coordinated scam attempting to bypass verification. When recipients of calls from 02 7245 4557 ask direct questions about the alleged security issues, the caller either disconnects or deflects. This pattern indicates the caller lacks genuine technical information and relies solely on pressure tactics rather than legitimate credentials.
