Phone Security Issues


Last week, Pindrop joined nearly 35,000 attendees at the NRF Annual Convention and EXPO in New York City. According to speakers from the event, retail brands will need to focus on their customers, their technology, and their leadership in 2017. Customer priorities are constantly adapting as available technology changes. These new innovations and technical capabilities will continue to transform the retail experience for customers, and brands will need to hone in on how to administer an experience that is not only timely, but also secure. According to Vishaal Melwani, CEO of menswear retailer Combatant Gentlemen, “there will be more emphasis placed on the omnichannel experience as companies continue to look for fresh ways to connect with consumers through the intersection of offline and online” in 2017.

While the retail experience is becoming increasingly omnichannel, retailers are still neglecting the phone channel, the weakest link in security, as a common point of access for customers. Despite the intent to administer positive customer experiences, contact centers agents often fall victim to the methods that enable fraud attacks. Today, Caller ID is freely spoofed and knowledge-based authentication questions (KBA’s) are easily bypassed. Criminals either socially engineer the answers, find them online, or purchase them on the black market. Fraud efforts are becoming increasingly aggressive in their attempts to fool contact center agents into processing fraudulent card-not-present (CNP) transactions.

According to Aite Group, an independent research firm, 72% of executives expect call center fraud loss to continue to grow, with $4 billion in counterfeit card fraud moving into the phone channel. These fraud attacks increase operational costs, decrease customer satisfaction, and jeopardize brand reputation as customer data is repeatedly lost to fraud. Retailers’ existing security systems are not robust or secure enough to handle the increasing volume of data filtering across web-enabled devices and processes. A digitally-influenced retail experience may enable brands to conduct business from a variety of access points, but it is also putting their enterprises under siege. By adopting next-generation security measures, including data loss prevention methods, cloud-based solutions, and contact center protection initiatives, retailers are sheltering sensitive digital content and lessening their exposure to fraud.

Businesses of all sizes need to assess which data is most at risk from a cyberattack and ensure their security solution protects against potential threats. Learn more.


Analysts at Aite Group have identified five key security and service steps that legacy solutions are failing to perform. These are the features that are keeping Caller ID, KBA, and voice biometrics from being viable anti-fraud and authentication solutions for the contact center. With 61% of account takeovers traced back to the contact center, this $400 million problem needs immediate resolve.

Protecting personal data in the contact center relies on a best-in-class security solution that benefits both the organization and the customer through:

  1. Universal Coverage. Customers must be authenticated and fraudsters must be identified on their first call. This prevents fraudsters from being able to enroll as illegitimate customers and alleviates customer privacy concerns.
  2. Accuracy. The right solution accurately differentiates between legitimate and illegitimate customers. Legacy solutions, such as Caller ID verification and KBA, fail to provide the accuracy needed.
  3. Speed. Contact center agents must be informed about the legitimacy of callers before they provide access to personal data. KBA takes a long time, which frustrates legitimate customers and offers fraudsters many chances to collect data.
  4. Low Friction. Customers want service that requires little effort on their part. Most voice biometrics solutions require an enrollment process, which leads to longer call times and lower customer satisfaction.
  5. Foolproof Technology. Fraudsters are currently using voice distortion, spoofing, social engineering, gateway hacking, and more to circumvent traditional security measures. The right solution needs to withstand these attempts to break through protection.

How do the largest global contact centers stop fraud and protect their customers?

According to a recent survey of 25 executives at 18 of the 40 largest US financial institutions, Phoneprinting is the highest ranked contact center anti-fraud solution. Pindrop’s patented technology analyzes 147 different factors in the audio of a phone call in order to create a unique signature that allows contact centers to accurately detect fraud. Avivah Litan, VP Distinguished Analyst at Gartner, describes phoneprinting technology and voice biometrics as “complementary technologies” that mutually benefit both contact center agents and security teams. This phoneprint allows a fraud analyst to create a unique signature for an illegitimate caller, while also determining the caller’s true geographic location, device type, and more. Unlike a phone number or a voice, this information is impossible for fraudsters manipulate. Phoneprinting allows Pindrop’s customers to catch over 80% of fraud calls with less than a 1% false positive rate.

Phoneprinting provides universal protection for all incoming calls to the contact center, allowing contact center agents to identify unknown attackers on their very first call while also creating a robust intelligent blacklist of known attackers. Contact centers are empowered with the technology necessary to stop fraud loss, reduce operations costs, protect brand reputation and compliance, and improve the customer’s overall experience.

Join Pindrop’s Director of Research, Dr. David Dewey, on November 15 to learn more about how Phoneprinting helps the largest global contact centers protect customers and fight fraud.



1. What are the key challenges of authenticating callers into the call center and IVR channels?

Traditional contact center anti-fraud and authentication methods no longer stand up to the advanced tactics leveraged by today’s criminals. Most contact centers rely on caller ID, a facility that identifies and displays the telephone numbers of incoming calls made to a particular line, but these telephone numbers can be easily spoofed. Contact centers also rely on knowledge-based authentication (KBA), asking questions that only the legitimate consumer can supposedly answer, to identify a caller. KBA has an average failure rate of 10-15%, and this rate can sometimes go as high as 30%. Most of these failures comes from legitimate customers, not criminals. Meanwhile, over 60% of these criminals can successfully answer these questions because of data they’ve already stolen.

2. What are the most effective methods for securing the phone channel?

“We need to reduce our reliance on static data,” says Avivah Litan, VP Distinguished Analyst at Gartner. All of the data compromises from the last few years have resulted in hoards of data being stolen by criminals and put into databases that are being resold to other criminals. Enabling accurate identity assessment in the contact center relies on endpoint-centric measures, which look at the originating call and the originating phone that is making that call in order to assess the legitimacy of the user that’s calling. Litan describes phoneprinting technology combined with voice biometrics as “the strongest method for detecting fraudsters who call into enterprises.”

3. What are call centers most concerned about and how are their needs satisfied?

Contact center and fraud teams have a mutual interest in protecting customers, their data, and the overall security and reputation of an organization. Call center agents aim to provide high levels of productivity and consistent customer satisfaction. Security teams aim to eliminate weak call center authentication processes and reduce dependence on call center agents for screening out fraudsters. Phoneprinting combined with voice biometrics provides user authentication and fraud detection, enabling both contact center and security teams.

blackhat2016Fraudsters live and die today by executing on what some may call — prank calls. Only the punchline hits businesses in their pockets, leaving law enforcement and companies to ask, “How do we know stop them?” They are robocalls, voice phishers and caller ID spoofers using cybercrime techniques to launch scam campaigns through the telephony channel that many people have long trusted.

Black Hat, one of the premier, highly technical security conferences of the year, welcomes Pindrop Labs Research Scientist Aude Marzuoli to host a session at Black Hat USA 2016.

I am excited for Marzuoli to discuss her latest research findings on the most menacing trends of the telephony channel and describe the calling patterns she tracked via a telephony honeypot. She will share with you her original thesis and how she used Pindrop’s honeypot to gather and analyze accurate and timely information on unwanted phone calls across the United States. By determining how these bad call sources can be quickly and accurately identified using features extracted from honeypot call audio, Pindrop Labs stands to aid law enforcement and businesses across the globe that are combatting rising telephony fraud.

Using machine learning and semantic information collected from honeypot call audio, Marzuoli and her team collected over 500,000 calls over five months from 90,000+ unique source phone numbers. Leveraging this data, Pindrop Labs developed a method to “fingerprint” high-risk call sources, attempting to hide behind phone numbers, and detect them in the first few seconds of a call.

In total, Marzuoli’s research included 1,072,840 calls placed to a honeypot by 209,755 sources and to 57,818 destinations. Out of these calls, she sampled over 100,000 for recording and analysis. The eye opening results were shared with Federal Communications Commission and the Federal Trade Commision. We look forward sharing to these results and what can be done to protect consumers and stop robocall scams.

I will be in the audience as she takes the stage and we will both be available after the session. I hope you will join us at Black Hat on August 4, 2016 at 5 pm PST in the South Seas CDF room. More details on her session are available here.
