Charter Communications has provided the following tips for businesses and consumers concerned about preventing telecommunications hacking and fraud:
Charter Business Customers Fraud Prevention
The following are some industry guidelines that, if followed could help reduce the risk of telephone hacking for businesses.
1. Evaluate your phone system's current settings and disable any features not in use such as the call forwarding feature.
2. If you do not need to make international calls and/or casual dialing (e.g., 10-10XXX + 1 + area code + phone number), block that ability with your phone provider.
3. Do not keep extensions active and remove inactive mailboxes for former personnel or positions.
4. Work with a phone equipment vendor to secure your phone system to ensure voicemail boxes have complex passwords. Periodically force password and authorization code changes for employees.
5. Familiarize yourself with your business' call patterns and monitor them regularly.
6. Ensure only trusted system administrators know the administrator password. Be sure to change passwords as soon as possible after any personnel changes.
7. Look for any suspicious call activity after hours, including weekends and holidays.
Charter Residential Customers Fraud Prevention
The following are some industry guidelines that, if followed could help reduce the risk of telephone or computer hacking for residential customers.
1. Be cautious when surfing the Internet and close pop-up boxes especially if it indicates "no credit card is needed" or a product or service is "free".
2. Install and run up-to-date anti-virus software and spyware removal tools.
3. Don't accept collect calls from people you don't know. By accepting a call, you have agreed to pay the phone charges.
4. Don't provide any information to individuals claiming to be law enforcement or telephone companies who ask you to accept collect calls or third-party calls as part of an investigation or repair/analysis project. Legitimate law enforcement and telephone officials will never ask you to accept collect calls or third-number charges.
5. Verify the identity of those who come to work on your equipment. Charter technicians or contractors will have proper identification with them at all times.
