Is Wiretapping a Threat to Business?

Cyberattacks are unauthorized and frequently malicious intrusions into digital systems and networks to compromise, disrupt, or steal data. These assaults can take many forms, but one especially malicious is Wiretapping. It is the covert interception and monitoring of electronic communications without other parties’ knowledge or consent. Also, it includes phone conversations, emails, or data transmissions. Wiretapping poses severe risks to privacy, security, and data integrity as digital communication becomes more important in personal and professional lives.


What is Wiretapping?

In cybersecurity, “Wiretapping” describes an illegal interception or monitoring of electronic communications, usually across a network or the Internet. It is a major invasion of privacy and can have significant ethical and legal consequences. Wiretapping is listening in on communication lines to record data between two or more parties or eavesdrop on conversations. It includes text messages, emails, voice calls, or other forms of digital communication. Wiretapping can be carried out physically by breaking into the network infrastructure or digitally by taking advantage of vulnerabilities in devices or networks. Additionally, it can be used for various purposes, including espionage, data theft, eavesdropping, and cyberattacks.

What are the Types of Wiretapping?

Physical Wiretapping

Physical Wiretapping is physically tapping into phone lines, communication cables, or other transmission means to intercept and monitor electronic conversations. This technique is related to listening in on talks using standard landline telephone networks. Moreover, it entails the attachment of hardware to phone lines. These gadgets made it possible for listeners to overhear voice conversations. However, due to increasingly stringent security measures and encryption standards, this type is typically challenging in digital networks.

Network-based Wiretapping

Network-based Wiretapping is a technique that allows an attacker to track and listen in on electronic communications as they pass across a computer network. It is often accomplished by getting illegal access to servers, switches, or routers on a network. Moreover, it may be done through methods like sniffing, in which an attacker gathers and examines network packets to draw out confidential data. Attackers can extract information from data packets, such as usernames, passwords, credit card numbers, or secret company information. Additionally, network wiretapping is passive because the attacker only watches the flow rather than actively altering the data. 

Digital Wiretapping

Digital Wiretapping involves intercepting and monitoring electronic conversations that take place digitally. It happens digitally, frequently across computer networks or the Internet. Attackers specifically target encrypted digital communications including Voice-over-IP (VoIP) conversations, instant messages, emails, and other platforms for communication. They infiltrate a target’s device using a variety of means, including malware, spyware, or sophisticated hacking techniques, and then they eavesdrop on their online interactions. Moreover, it is also passive since attackers only view and intercept communication flow without actively altering or interfering with it.

Email Wiretapping

Email Wiretapping refers to the unauthorized interception and monitoring of email communications. It entails secretly reading email messages exchanged between people or organizations without their knowledge or permission. Furthermore, it involves recording and keeping track of email messages as they are sent over the Internet or through the infrastructure of an email service provider. Attackers snoop on email content to access the data, such as intellectual property, financial information, or personal information.

How to Prevent Wiretapping?


Emails, text messages, and other digital communications should be secured using encryption technologies and protocols. End-to-end encryption makes sure that only the intended receiver can decrypt and read the communication.

Network Monitoring

Use network monitoring software and intrusion detection systems to spot any suspicious network activity, including possible eavesdropping attempts.

Communication Paths

Use secure communication methods to safeguard data while it is being transmitted and prevent illegal interception, such as SSL/TLS for online surfing or VPNs for remote access.

Regular Software Update

Keep operating systems, applications, and security software regularly updated to fix vulnerabilities that attackers could exploit.

Secure the Device

Install reliable antivirus and anti-malware software. These tools can assist in identifying and getting rid of malicious software that could be used for Wiretapping.

Use Strong Passwords

For accounts, especially those for email and online services, create secure, unique passwords. To provide an additional layer of protection, activate multi-factor authentication.

Beware of Phishing

Be wary of unauthorized calls, emails, or texts. Avoid opening attachments or clicking on links coming from unidentified sources. Even if they seem to originate from reliable sources, confirm the validity of requests for sensitive information.

Infrastructure Security

To prevent unwanted access, monitor network cabinets, cables, and communication connections. Establish access restrictions and security measures to stop tampering with communication devices.


Wiretapping in cybersecurity refers to the illegal interception of electronic communications for malicious purposes. It poses significant threats to privacy, security, and data integrity. So businesses and professionals should protect against Wiretapping and implement robust security measures. They should also stay informed about common cybersecurity threats and techniques used in Wiretapping. Professionals can enroll in CISM Certification Training to gain knowledge of various cybersecurity attacks. Trainees thoroughly grasp methods to protect against other cybersecurity attacks.
