As digital communication evolves, Voice over Internet Protocol (VoIP) has become a popular communication tool for businesses and individuals alike. However, with its increased usage, it has also become a target for cybercriminals. The digital nature of VoIP makes it susceptible to various forms of cyber-attacks.
This article will explore the top 10 common VoIP attacks and discuss how to protect against them.
1. VoIP Phishing Attacks
Phishing is a common cyber-attack levelled at VoIP systems. Cybercriminals pose as a trustworthy entity to trick individuals into revealing sensitive information like passwords and credit card details. To prevent this, users should be cautious about unsolicited calls requesting personal information. Employing voice and data cabling solutions can also provide a secure network infrastructure that limits the chances of a successful phishing attack.
2. Denial of Service (DoS) Attacks
In a DoS attack, the cybercriminal overwhelms the VoIP system with unnecessary requests, causing it to crash and denying service to legitimate users. One way to prevent this is to install firewalls and intrusion prevention systems. Regularly updating these systems can help maintain their efficiency.
3. Man-in-the-Middle Attacks
In this form of attack, a cybercriminal intercepts communication between two parties, usually to steal sensitive information. To prevent this, you can use encryption tools, which make the data indecipherable to anyone without the correct decryption key.
4. Call Interception
Cybercriminals can also eavesdrop on VoIP calls to gather valuable information. Using voice and data cabling solutions can enhance the security of your VoIP system and reduce the risk of call interception.
5. Vishing Attacks
Vishing is a form of phishing where voice communication is used to trick individuals into revealing sensitive information. The best defence against vishing is user awareness. Training staff on the signs of potential vishing attacks can help them avoid falling victim to these scams.
Malware can be used to disrupt VoIP services or steal sensitive data. Regularly updating your VoIP software can help protect against malware. You should also install reputable antivirus software and keep it updated.
7. SPIT (Spam over Internet Telephony)
SPIT involves receiving unsolicited messages over VoIP. To protect against SPIT, consider implementing SPIT-blocking software or services.
8. Call Tampering
Call tampering involves altering the properties of a call, such as a caller ID, to mislead the receiver. To protect against this type of attack, consider using secure voice and data cabling solutions.
9. Registration Hijacking
In registration hijacking, a cybercriminal takes over a VoIP user’s account, often to make long-distance calls at the user’s expense. To prevent this, use strong, unique passwords for your VoIP accounts and change them regularly.
10. Eavesdropping and Call Recording
Eavesdropping and call recording can lead to serious breaches of privacy and data theft. To prevent this, consider employing voice and data cabling solutions for a secure VoIP setup.
