Phone Security Issues


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.



The wealth of information housed by contact centers can be leveraged by fraudsters for data mining and cross-channel attacks. In an effort to prevent phone fraud, many businesses implement authentication methods; however, most fail to administer the authentication required to provide a layered defense system. As social engineering and fraud technologies have become more advanced, standard authentication methods have proven to become less sufficient. “You have to assume the criminals can get through one layer [of authentication]; they can get through two, they can even get through three,” says Avivah Litan, Vice President with the consultancy Gartner. “But if you have multiple layers, up to five, and you’re continuously authenticating that user and continuously looking at their activities against their profile, you should be in pretty good shape.”

Multiple layers of security allow organizations to meet regulatory requirements and effectively safeguard customer data. Knowledge-based authentication (KBA), has served as a standard authentication method for years; however, 10-15% of KBA fails entirely, proving that authentication requires another layer of security in order to ensure data protection. A layered approach to authentication starts with “protecting the endpoint, trying to secure the browser, going all the way up to looking at the navigation, building profiles of users and accounts and looking for anomalies, doing that across channels,” says Litan. This kind of identity assessment analyzes endpoint and user data, metadata, and ehavior as it identifies linkages across and between entities.


No singular authentication method used on its own is sufficient enough to keep determined fraudsters out. Creating a layered defense system makes it more difficult for an illegitimate caller to access desired information, such as a physical location, computing device, network, or database. If one barrier is broken or compromised, the fraudster still has at least one more barrier to breach before successfully accessing the desired information. This system ensures that each layer defends the previous layer, making it more difficult for a fraudster to circumvent the security of the entire system.

Aite InfographicAite Group, an independent research and advisory firm focused on business, technology, and regulatory issues, interviewed 25 executives at 18 of the top 40 largest U.S. financial institutions based on asset size in order to provide an accurate evaluation of the most effective technology solutions to protect against fraud. On Tuesday, Aite’s Senior Analyst, Shirley Inscoe, joined Pindrop’s Director of Research, Dr. David Dewey, for an online discussion of the growing threat of fraud in the contact center.

Top 10 Takeaways

  1. As EMV continues to gain momentum in the US, organized fraud rings will move to the phone channel, replacing traditional counterfeit card fraud.
  2. The contact center is the cross-channel fraud enabler. Current authentication factors in the contact center often fail due to various data fraudsters can acquire through social engineering tactics.
  3. The majority of financial institutions (72%) expect contact center fraud loss to continue in an upward trajectory.
  4. The root source of fraud, the contact center, is often misdiagnosed due to fraud enablement in other channels, such as debit card, credit card, and check order takeover – online fraud that exists from reset credentials being reset by the contact center agent.
  5. Fraud will move downstream toward smaller institutions and credit unions as phone fraud solutions are integrated into larger firms.
  6. Organized fraud rings are using automated attacks, specifically robotic fraudsters, targeting interactive voice recordings (IVRs), to keep their cost down while still managing to dramatically increase market coverage.
  7. In the U.S., Contact center fraud is expected to double to a $775 million problem by 2020.
  8. 61% of account takeover losses trace back to the contact center.
  9. For every 1-second authentication is reduced, an organization can save $1 million annually.
  10. Of the 23 different technology solutions reviewed by leading executives, Pindrop’s phoneprinting and voiceprinting technologies hold the highest combined ranking on industry awareness of the product, overall product ranking, and likelihood of recommending to colleagues.

75% of Tuesday’s webinar attendees confirmed having seen a recent rise in fraud. Contact centers will continue to enable cross-channel fraud until technology solutions are implemented to thwart it. Ensuring optimal protection against fraud in the contact center requires multiple layers of security that provide high coverage, high accuracy, high speed, and low friction without being easily fooled by fraud techniques, such as spoofing, voice distortion, and social engineering. Pindrop’s technology provides multi-factor authentication through layered intelligence scores, reason codes, and risk factors.

TWIPF2 This week in phone fraud, Pindrop’s CEO discusses voice authentication and Chinese and Taiwanese fraudsters arrested in Turkey.

This week, Financial Times met with Pindrop CEO, Vijay Balasubramaniyan, to discuss the future of voice authentication. Voice is an “extremely rich” and quick way of authenticating someone’s identity.

GB Times reported after an over 70 Chinese wire fraud suspects were deported from Kenya to China in April, a gang of Chinese and Taiwanese fraudsters were arrested in Turkey on suspicion of phone fraud. The gang reportedly stole information from over 3,000 Chinese tourists.




Forbes: Scam Alert: Why the IRS won’t call you – Fraudsters frequently use psychological attempts to scare people into give up personal information used for identity theft. Once the fraudsters have possession of that sensitive information, they can open credit accounts and start stealing away.

The UK sees more than 2x the amount of  call center fraud than the US

The UK is no stranger to phone fraud in financial institutions. The recent data compiled in 10-global-phone-fraud-rates-01Pindrop’s 2016 Call Center Fraud Report shows that 1 in every 700 calls made to enterprise call centers in the UK is fraudulent. This is over two times higher than the fraud call rate in the US.

A major factor that’s causing the high levels of fraud in the UK is the chip card technology implemented in 2004. Because chip cards make it harder to commit card-present fraud, attackers began to move towards card-not-present channels, notably the call center, to continue making fraudulent transactions.

This shift gives the US valuable insight into the future of call center fraud due to the recent transition of chip-and-pin cards stateside. According to the Aite Group, fraud attacks in the call center grew 79% in the UK following the chip card roll out.

Fraud calls in the UK are mostly domestic

72% of fraud calls to financial institutions originate within the UK. The US sees a much lower number of domestic calls at only 48%. Again, the high percentage in domestic fraud calls is linked to chip cards. When chip cards were first introduced in Europe, card-present fraudsters moved to non-physical attacks like call center fraud, rather than relocate out of the country. In addition to the UK, similar trends have been seen in other European countries who have implemented chip cards. France, for example, saw an increase in domestic card-not-present attacks by more than 360% between 2004 and 2009 (Iovation, Fighting CNP Fraud: 5 Things to Consider).


Most UK fraud comes from mobile devices

UK financial institutions see 64% of fraud calls coming from mobile devices, while the US only sees 37%. In the UK, it is easier to program mobiles phones to show a restricted caller ID. In fact, 70% of fraud calls in the UK use a restricted caller ID rather than spoofing a phone number, a common trick in the US.


The state of call center fraud in the UK gives us a glimpse into the future of fraud in the US. Phone fraud has risen 45% since 2013 stateside. Fraudsters will go down the path of least resistance, which in financial institutions is the phone channel. As physical and cyber security increases and data breaches become more frequent, bad actors exploit data over the phone. To combat fraud, financial institutions should implement security solutions around authentication and voice biometrics to ensure the safety of their customers.
