Detailed Analysis
**Impact** At least 10 reported cases in Singapore since February have resulted in losses totaling approximately $1.7 million. Victims span individual users who were targeted through their personal devices. Financial losses occurred due to unauthorized bank transfers and credential theft, with potential exposure of banking information. The scam also risks operational disruption through remote access to victims’ devices. **Technical Details** The attack begins with a browser pop-up alert falsely claiming the victim’s device is compromised, prompting them to call an internet-based phone number starting with “3.” Victims are then transferred to scammers impersonating police officers who coerce them into transferring funds or providing banking credentials. Remote access tools are installed via links or downloads to facilitate control over victims’ devices and accounts. No specific malware names, CVEs, or infrastructure details were provided. **Recommended Response** Users should avoid calling phone numbers displayed in pop-up alerts, refrain from clicking links or buttons within suspicious messages, and close such alerts by exiting the browser. If compromised, disconnect from the internet immediately, remove unauthorized applications, perform a full antivirus scan, and change all passwords from a trusted device. Financial institutions should monitor for unauthorized transactions and added payees. Reporting incidents to police and CSA’s SingCERT is advised. No patch or specific detection signatures were provided.
