Phone Hacking or Phreaking
This article was written by ICA and published in the Stockport Times on Thursday 16th February 2012.
Whilst most of us have heard about the News of the World and their well publicised hacking into mobile phones through the voicemail, maybe not as many of us are aware that this phone hacking or phone phreaking is affecting businesses everyday. This is not limited to the UK but is a worldwide phenomenon, organised by major crime syndicates to create and launder money. It is estimated that this costs UK businesses between £1.3 billion and £1.5 billion each year!
Pre-Internet Beginnings
Prior to the internet the UK Post Office used to manage the telephone network before British Telecom was created and privatised. Hackers were able to hack into the telephone network using a series of tones to fool the system into allowing them to make free long distance calls. Often these hackers did it to prove that it could be done rather than any malicious attempt to create the industry that it now is. Now hackers access business telephony systems through the voicemail ports to make huge numbers of calls to other systems and abroad.
Facts and Figures
- The average monetary cost to a UK business is £10,000, though there is considerable time and effort spent afterwards resolving the situation too.
- Numbers called are abroad and Premium rate numbers, the most expensive
- Organisations are typically phreaked over night, or more likely, over the weekend.
- Notable organisations such as the White House and Scotland Yard have been victims previously. Companies are obviously reluctant to admit being phreaked!
What Can You Do?
There are a number of measures that can be taken to ensure that your telephone system is protected.
- Should you have more than one individual with access to the telephone system then make sure that they have different access codes.
- Immediately disable remote access codes if staff leave your organisation.
- Change your access codes and passwords from the default settings.
- Store your password information securely
- Do NOT use easy passwords such as 1234.
- Review itemised call bills
- Ask your provider about their monitoring policy.
