What is phone hacking?


There are many types of phone hacking and phone-taping that are conducted legally by police and illegally by newspaper reporters, private investigators, spies and other people and groups. Hacking in the latest instance means getting access to another person's voicemail. The vulnerability occurs because the phone companies have developed systems which allow you the owner of the phone, to access your messages remotely, using another land-line phone or cell-phone. The same vulnerability applies to any message banks on your land-line phone as well. You as owner of the phone can simply ring the number, enter a pin number and the messages will be replayed for you to listing to. But others can hack into this tool and access your voice mail.

For many of the older phones a default pin number was set for the phone when it was purchased. Uses could change their pin number, but many uses didn't not bother, and so there were a huge number of phones with the same default pin number such as "1111", "9999", "1234" etc. All the hacker had to do was call your number when it was engaged or the phone was turned off, enter a default pin associated with the brand of phone you were using and they would have access to your inbox.

Many people publish their mobile numbers on websites, in emails and in social media sites such as Twitter and Facebook.The provider can often be identified by Googling the whole number or part of it. Various providers have different systems associated with pin numbers, ways of accessing you voice mail and default pin numbers. So once the phone number and provider were known it was a simple matter of trying the default pins. In some cases personalised pins could be obtained illegally from various websites on the internet. Also A four number pin is relatively easy to hack simply by trial and error, especially when many people use part of their birth date, mother's maiden name and other codes that can be found in various ways.

What is Caller ID Spoofing?


Caller ID Spoofing is a system which allows you phone someone and to pose as another phone number. A relatively simple bit of software or a website is used to do this. The hacker is prompted to enter the phone number he wants to call, and the phone number he wants to masquerade as calling from. The system is tricked into thinking the call is coming from the owner’s phone. Many cell phone providers have systems which skip the pass code when the call is initiated from the handset owned by the consumer. Hackers can then access the voicemail without entering a pass code.

Are Newer Phone Safer Now?


The network providers have tighten up the access to mail messages. Default PINs are no longer allocated. New phone owners are required to set up their own PIN when setting the voicemail. That at least makes it harder for hackers, though it can still be done, especially if you make it easier for them. Picking a PIN with recurring or sequential numbers (4444 or 1234 for example) or your birthday or other personal codes that can be easily found should avoided.

How does Social media increase the risks?


Twitter, Facebook and other social networks represent a potential hazard. Some people put far too much personal information on their profile page on Facebook. This may include their mobile phone number, date of birth, their address.

Disclosing location information can also be a risk. Many people like to 'check in' and tell their followers and friends where we are. Hackers can then target that location to ease-drop on your conversations. This also tells criminals where you aren't - that is you are not at home and your house is vacant and ripe for burglars to pay a visit.

What is Text and SMS spoofing?


SMS spoofing is a relatively new technique which uses SMS to replace the originating mobile number (Sender ID) with alphanumeric text. The new text can fool the person receiving the call into believing it is from a trusted source. It may also be used to fool the provider into believing the message requesting a pin number came from the owner rather than a hacker. Spoofing has legitimate uses such as for company name identification, caller identification etc. But it can have illegitimate uses, such as impersonating company, another person or product.
