A person or an organization can infiltrate a business phone system through different means:
Social engineering scams: Persuading employees to provide confidential information
Eavesdropping: Listening in on business calls without the person knowing
Malware: Injecting malware into apps, websites, or browsers and employees unknowingly downloading the malicious software
Being vulnerable to hackers is one of the disadvantages of VoIP, with bad actors disrupting normal business operations and extorting money. To reduce the risk of falling victim to VoIP hacking, companies must enforce strong security measures, such as using virtual private networks (VPNs) for remote access, implementing two-factor authentication, updating VoIP firmware, and conducting regular audits.
