Telephone Denial of Service (TDoS) attacks are on the rise, and no business is exempt from this security risk. While phone spam is not a new threat to businesses, risks to your communication systems have evolved.
Today's hackers are using sophisticated malware to infect smartphones and flood the phone systems of agencies or companies with spoofed phone calls, resulting in phone line unavailability for legitimate callers.
The growth of TDoS is so concerning, the FBI and Department of Homeland Security (DHS) have issued warnings to businesses about this risk. If a telephone-based DOS attack targets your organization, you may suffer consequences that are even worse than phone system downtime. TDoS attacks can be used as a "smokescreen," or distraction from other information security threats against your network. Increasingly, TDoS targets also face extortion demands to pay a ransom to stop the attack.
While the Internet Crime Complaint Center has received thousands of reports about TDoS attacks, there have only been a few convictions to date. TDoS attacks equally impact every kind of phone system, regardless of whether a business is using traditional phone technology, premises-based systems, or voice-over-IP (VoIP) telephony. To protect your brand, it’s time to determine your risk level, evaluate solutions, and create a plan for response.
