What is Voicemail Hacking? 

What is Voicemail Hacking

Voicemail hacking is defined as unauthorized access to one’s voicemail account. By this, the hacker is able to delete, listen to, or even exploit messages from hacked voicemail systems. 

This involves listening to messages without the account holder’s knowledge by hacking into weak points in the voicemail system. 

Most voicemail systems allow remote access for users who wish to check their voice messages or revise their greetings. To do this, you can call your own mobile number and type a PIN or password when you reach the voicemail. 

Attackers can perform illegal activity using various methods, such as social engineering techniques, which trick individuals into divulging personal information, or by exploiting voicemail systems that use weak or default PINs.

Voicemail system hacking involves guessing voicemail passwords or PINs or discovering a way around it. This alarming breach allows unauthorized individuals to listen to stored messages, which could include sensitive personal or business information. 

How do Hackers Gain Access to Your Voicemail? 

A hacker tries to exploit your voicemail by guessing pins, passwords, or combinations to gain access to the system. The voicemail boxes may still have the default pins and passwords, so hackers can easily hack into your voicemail system. 

Hackers break into voicemail systems to steal personal or financial details or access your accounts by intercepting two-factor authentication codes. 

They can alter voicemail account settings, changing outgoing messages to receive expensive international collect calls. They can also utilize the call-forwarding feature to send calls to international numbers and make unauthorized calls using your account.

Hacking Method How It Works Example
Guessing Weak Passwords Hackers try default or easy passwords (like “1234” or birthdates) to gain access to your voicemail. They call your voicemail and try passwords like your birth year (e.g., “1985”).
Exploiting Call Forwarding They configure the voicemail’s call-forwarding feature to redirect calls to international numbers for unauthorized use. Your calls are forwarded to a number in another country, racking up charges. 

Things You Should Know: 

  • Hackers break into business voicemail systems during holidays or weekends when businesses are not cautious. 
  • Hackers are usually international, with calls from different countries around the world.
  • In international call scams, businesses won’t know they are hacked until the phone company reports it. 
  • Hackers can rack up high phone bills. 
  • Hackers can change voicemail greetings to intercept calls or information. 

How to Tell if Your Voicemail Has Been Hacked?

If you think your voicemail has been hacked, then watch out for these signs:

  1. Unexpected Voicemail Messages, Unsolicited Texts or Emails
    If you receive strange or unfamiliar voicemail messages, it could be a sign that someone else is accessing your account.
  2. Voicemail Password Changes
    If your voicemail password has been changed without your knowledge, it’s a clear sign that your voicemail might have been hacked.
  3. Unusual Activity or Calls
    Notice any unfamiliar incoming or outgoing calls from your voicemail? Hackers may use your system to make calls or forward messages.
  4. Unexplained Phone Bill Charges
    If your phone bill suddenly has unexpected international or long-distance charges, hackers may have been using your voicemail system to make unauthorized calls.
  5. Voicemail Is Full, but You Didn’t Fill It
    If your voicemail inbox suddenly shows as full without you receiving many messages, hackers might be using it to store their own messages or fill it with spam.
  6. Unusual Outgoing Messages
    If you hear a different voicemail greeting than the one you set, hackers may have changed it to redirect calls or impersonate you.
  7. Unfamiliar Phone Numbers in Voicemail Inbox
    If you see unknown phone numbers in your voicemail inbox, especially from international or unusual locations, it’s a red flag.
  8. Two-Factor Authentication Alerts
    If you receive notifications about two-factor authentication attempts that you didn’t make, hackers may be intercepting codes sent to your voicemail.
  9. Slower Phone Performance
    If your phone starts acting slow or behaving strangely, it could be due to malicious software running in the background, which might be linked to a compromised voicemail system.

Precautions to Prevent Voicemail System Hacking Scheme

Precautions to Prevent Voicemail System Hacking Scheme

1. Create a Strong and Unique PIN

The first step towards protecting your voicemail starts with a strong PIN. We usually put default passwords like “0000” or “1234” which are way too easy for hackers to guess. So change your PIN to something random and at least six digits long. Do not use obvious passwords like your birthday or phone number. 

Updating your PIN regularly is just as important. Set a reminder to change it every few months. 

2. Turn On Two-Factor Authentication

Enable two-factor authentication (2FA) for extra protection. With 2FA, you’ll need a second form of ID sent to your phone system to access your voicemail. Even if someone guesses your PIN, they can’t access it without that code.

This extra layer of security helps protect not just your voicemail but any accounts linked to it, like banking or social media.

3. Disable Remote Access (If You Don’t Need It)

Sure, remote access sounds handy, but it’s also a typical tactic for hackers. So, if you don’t really need it, turn it off. Ask your phone provider to disable it. Because disabling remote access, if not required, adds an extra layer of security. 

4. Keep an Eye on Your Voicemail Settings

Hackers can change your voicemail settings, like changing your voicemail greeting or turning on call forwarding. So, it’s a great idea to check your settings from time to time. Check if there are any alterations to your voicemail greeting or settings. 

If you think your voicemail system is hacked or notice anything unusual, then update your PIN and let your phone system provider know. 

5. Avoid Public Wi-Fi for Voicemail

We love free public Wi-Fi, dont we? But it’s very risky. We should never use public wifi to access our sensitive information or systems like voicemail or bank accounts because public wifi is very easy to exploit. 

So always stick to trusted networks and keep your private messages private! It’s an easy habit that can go a long way toward keeping hackers out.
