What are the key takeaways from Pindrop’s 2024 Voice Intelligence and Security Report regarding the current state of voice-based fraud and security?
The report provides a deep dive into pressing security issues and future trends, particularly within contact centers serving financial and non-financial institutions. Key findings in the report include:
- Significant Increase in Contact Center Fraud: Contact center fraud has surged by 60% in the last two years, reaching the highest levels since 2019. By the end of this year, one in every 730 calls to a contact center is expected to be fraudulent.
- Increasing Sophistication of Attackers Using Deepfakes: Deepfake attacks, including sophisticated synthetic voice clones, are rising, posing an estimated $5 billion fraud risk to U.S. contact centers. This technology is being leveraged to enhance fraud tactics such as automated and high-scale account reconnaissance, voice impersonation, targeted smishing, and social engineering.
- Traditional methods of fraud detection and authentication are not working: Companies still rely on manual authentication of consumers which is time-consuming, expensive and ineffective at stopping fraud. 350 million victims of data breaches. $12 billion spent yearly on authentication and $10 billion lost to fraud are evidence that current security methods are not working
- New approaches and technologies are required: Liveness detection is crucial to fighting bad AI and enhancing security. Voice analysis is still important but needs to be paired with liveness detection and multifactor authentication.
According to the report, 67.5% of U.S. consumers are concerned about deepfakes in the banking sector. Can you elaborate on the types of deepfake threats that financial institutions are facing?
Banking fraud via phone channels is rising due to several factors. Since financial institutions rely heavily on customers to confirm suspicious activity, call centers can become prime targets for fraudsters. Fraudsters use social engineering tactics to deceive customer service representatives, persuading them to remove restrictions or help reset online banking credentials. According to one Pindrop banking customer, 36% of identified fraud calls aimed primarily to remove holds imposed by fraud controls. Another Pindrop banking customer reports that 19% of fraud calls aimed to gain access to online banking. With the rise of generative AI and deepfakes, these kinds of attacks have become more potent and scalable. Now one or two fraudsters in a garage can create any number of synthetic voices and launch simultaneous attacks on multiple financial institutions and amplify their tactics. This has created an elevated level of risk and concern amongst consumers about whether the banking sector is prepared to repel these sophisticated attacks.
How have advancements in generative AI contributed to the rise of deepfakes, and what specific challenges do these pose for security systems?
While deepfakes are not new, advancements in generative AI have made them a potent vector over the past year as they’ve been in a position to change into extra plausible at a a lot bigger scale. Developments in GenAI have made giant language fashions more proficient at creating plausible speech and language. Now pure sounding artificial (pretend speech) could be created very cheaply and at a big scale. These developments have made deepfakes accessible to everybody together with fraudsters. These deepfakes problem safety techniques by enabling extremely convincing phishing assaults, spreading misinformation, and facilitating monetary fraud via sensible impersonations. They undermine conventional authentication strategies, create vital reputational dangers, and demand superior detection applied sciences to maintain up with their speedy evolution and scalability.
How did Pindrop Pulse contribute to figuring out the TTS engine used within the President Biden robocall assault, and what implications does this have for future deepfake detection?
Pindrop Pulse performed a vital function in figuring out ElevenLabs, the TTS engine used within the President Biden robocall assault. Utilizing our superior deepfake detection know-how, we carried out a four-stage evaluation course of involving audio filtering and cleaning, function extraction, section evaluation, and steady scoring. This course of allowed us to filter out nonspeech frames, downsample the audio to duplicate typical telephone situations and extract low-level spectro-temporal options.
By dividing the audio into 155 segments and assigning liveness scores, we decided that the audio was persistently synthetic. Utilizing “fakeprints,” we in contrast the audio in opposition to 122 TTS techniques and recognized with 99% probability that ElevenLabs or an identical system was used. This discovering was validated with an 84% probability via the ElevenLabs SpeechAI Classifier. Our detailed evaluation revealed deepfake artifacts, notably in phrases with wealthy fricatives and unusual expressions for President Biden.
This case underscores the significance of our scalable and explainable deepfake detection techniques, which improve accuracy, construct belief, and adapt to new applied sciences. It additionally highlights the necessity for generative AI techniques to include safeguards in opposition to misuse, guaranteeing that voice cloning is consented to by actual people. Our strategy units a benchmark for addressing artificial media threats, emphasizing ongoing monitoring and analysis to remain forward of evolving deepfake strategies.
The report mentions vital issues about deepfakes affecting media and political establishments. Might you present examples of such incidents and their potential impression?
Our analysis has discovered that U.S. shoppers are most involved in regards to the danger of deepfakes and voice clones in banking and the monetary sector. However past that, the specter of deepfakes to harm our media and political establishments poses an equally vital problem. Outdoors of the US, the usage of deepfakes has additionally been noticed in Indonesia (Suharto deepfake), and Slovakia (Michal Šimečka and Monika Tódová voice deepfake).
2024 is a major election yr within the U.S. and India. With 4 billion individuals throughout 40 international locations anticipated to vote, the proliferation of synthetic intelligence know-how makes it simpler than ever to deceive individuals on the web. We count on an increase in focused deepfake assaults on authorities establishments, social media firms, different information media, and the final inhabitants, which are supposed to create mistrust in our establishments and sow disinformation within the public discourse.

This pivotal discovering underscores the significance of conducting detailed and goal analyses earlier than making public declarations in regards to the nature of doubtless manipulated media.
At a big US financial institution, Pindrop found {that a} fraudster was utilizing artificial voice to bypass authentication within the IVR. We discovered that the fraudster was utilizing machine-generated voice to bypass IVR authentication for focused accounts, offering the fitting solutions for the safety questions and, in a single case, even passing one-time passwords (OTP). Bots that efficiently authenticated within the IVR recognized accounts value concentrating on by way of primary steadiness inquiries. Subsequent calls into these accounts had been from an actual human to perpetrate the fraud. Pindrop alerted the financial institution to this fraud in real-time utilizing Pulse know-how and was in a position to cease the fraudster.
In one other monetary establishment, Pindrop discovered that some fraudsters had been coaching their very own voicebots to imitate financial institution automated response techniques. In what gave the impression of a weird first name, a voicebot referred to as into the financial institution’s IVR to not do account reconnaissance however to repeat the IVR prompts. A number of calls got here into totally different branches of the IVR dialog tree, and each two seconds, the bot would restate what it heard. Every week later, extra calls had been noticed doing the identical, however right now, the voice bot repeated the phrases in exactly the identical voice and mannerisms of the financial institution’s IVR. We consider a fraudster was coaching a voicebot to reflect the financial institution’s IVR as a place to begin of a smishing assault. With the assistance of Pindrop Pulse, the monetary establishment was in a position to thwart this assault earlier than any broken was triggered.
Unbiased NPR Audio Deepfake Experiment: Digital safety is a continually evolving arms race between fraudsters and safety know-how suppliers. There are a number of suppliers, together with Pindrop, which have claimed to detect audio deepfakes persistently – NPR put these claims to the check to evaluate whether or not present know-how options are able to detecting AI-generated audio deepfakes on a constant foundation.
