In our rapidly evolving digital world, many wonder whether phone calls can be used as a hacking method. The common question is: βCan a phone be hacked through a voice call?β This article explores the truth behind this concern, potential hacking methods, and how to protect your device from such threats.
π Can a Phone Really Be Hacked Through a Call?
β Short Answer: Yes, but not in the way you might think.
β A traditional phone call via GSM or 4G networks cannot directly hack your phone.
β οΈ However, certain vulnerabilities in VoIP apps (e.g., WhatsApp, Skype, or Viber) can be exploited.
In some cases, hackers have leveraged security flaws to infect phones simply by making a call, even without the user answering it.
π¨ How Hackers Use Phone Calls to Compromise Devices?
1οΈβ£ Exploiting VoIP App Vulnerabilities
π Some communication apps may contain software bugs that allow malicious code execution.
π Example: In 2019, a flaw in WhatsApp enabled spyware installation via an unanswered call.
2οΈβ£ Social Engineering Attacks
π Hackers use psychological manipulation to trick victims into revealing sensitive information, such as passwords or verification codes.
3οΈβ£ Exploiting Outdated Network Protocols (SS7 Attacks)
π‘ Older telecom protocols (e.g., SS7 vulnerabilities) allow attackers to intercept calls, track locations, and hijack SMS-based authentication.
4οΈβ£ Vishing (Voice Phishing) Scams
ποΈ Similar to phishing, fraudulent callers impersonate trusted entities (banks, tech support, etc.) to steal personal data.
π‘οΈ How to Protect Your Phone from Call-Based Hacks?
π Keep your system and apps updated to patch known vulnerabilities.
π« Avoid answering unknown or suspicious calls, especially from international numbers.
π± Download communication apps only from official sources (Google Play, App Store).
π Enable Two-Factor Authentication (2FA) for apps linked to your number.
π‘ Use security apps to detect malware and potential threats.
π Never share sensitive details (passwords, OTPs) over the phone.
β οΈ Signs Your Phone May Be Compromised
π Rapid battery drain.
π’ Unusual phone slowdowns.
π Unexpected calls or messages.
π₯ Overheating without heavy use.
π² Presence of unknown apps.
