We’re all familiar with eavesdropping on phone calls but do you know that this can be done on VoIP calls too? Read on to know how the whole thing works and how to protect yourself from such a scenario.
There are some common methods to eavesdropping. First up is through the parallel phone which means the phone being used to eavesdrop is connected to the same phone line as the original one. This technique works not only on wired phones but on radio phones as well. All you have to do is tune to the phones so that they work on a similar frequency. The second method is by installing a bug into the phone line but then again, this works only on stations with wired phones.
By far the most popular technique though is by installing the bug into the phone switchboard. Mostly used by authorities such as the FBI and police, this works on mobile phones as well. Moreover, they can connect the high-level network and get to intercept a million calls all at the same time. By using the vulnerabilities of today’s smartphones, an eavesdropping bug can be installed into your mobile’s memory core. Such applications can gain access to make all your calls visible.
But how does one intercept VoIP calls? As you know, the protocol of VoIP works by sending the information over the net or LAN. Compressed in voice packages, this information is sent together with other packages. It basically works the same way as uploading a file on an internet server. Being this the case, it’s now crystal clear if a person has the access or has hacked the PC from where your traffic is coming through can also have access to the voice packages.
The good news though is that these packages are actually encrypted and even if acquired, those with malicious intent can’t gain anything over their illegal actions. Major developers of VoIP have ensured that an array if different encryption protocols are provided to ensure that your calls are safer. What’s more, this comes in both free and paid programs. The simplest encryption of VoIP is called the Zfone which is free but needs to be installed for both talkers. Other calls though are not protected.
Another protection option is by organizing a separate but protected LAN and have all the VoIP phones connected to it. This is limited though only to the local level. A closed paid encryption protocol can provide protection only for your personal information while the protocol is unknown at a relatively short time period. Because of leaks in information and hacking attempts, such protocols easily become insecure as well.
By now, you are already aware that a major portion of VoIP calls get intercepted when the packages get to a client’s PC and are decrypted. Given this situation, what you need to is make your VoIP calls safe so that your network is safe too. You see, a hacker would find it easy to hack your PC and install an application to steal decrypted voice packages compared to intercepting them at a network of high-level and exert effort in cracking the encryption protocol on his own.
The best thing to do is also to employ firewalls and the recent versions of antimalware apps to ensure that your information stays safe. It has happened before that over 90% of a particular corporate data was stolen because of Wi-Fi networks vulnerabilities. There are times though when it’s a necessity to use a wireless network with no other options. In such a case, you need to bear in mind that hackers can connect to your wireless network due to accessibility even from a great distance.
