After extensive research into global banking fraud techniques, examining evidence from cybersecurity experts, financial institutions, and law enforcement agencies worldwide, including cases from the United States, United Kingdom, India, Pakistan, Singapore, and other countries, one thing becomes crystal clear: the widespread belief that silent phone calls can automatically hack bank accounts or drain funds without victim participation is a dangerous myth that needs immediate debunking.

Myth-Busting: Separating Fiction from Reality
The Silent Call Banking Hack Myth
❌ MYTH: A few-second silent call can automatically install software, hack your phone, and drain your bank account without any action from you.
✅ REALITY: No credible evidence exists anywhere in the world—from the US to India to Pakistan—that supports the claim that answering a silent call can automatically compromise banking apps or drain accounts.
The “Automatic Software Attachment” Myth
❌ MYTH: Malicious software can be “attached” to your phone simply by receiving a voice call.
✅ REALITY: Standard telecommunications voice calls cannot transmit executable files or install malware. This is technologically impossible with current phone systems.
The WhatsApp Zero-Click Myth
❌ MYTH: Any WhatsApp call from unknown numbers automatically hacks your account.
✅ REALITY: While extremely rare zero-click exploits have existed (like Pegasus spyware), these were quickly patched, targeted only high-profile individuals, and were not used for mass banking fraud.
