Why You Shouldn't Respond to Voicemails from Unknown Callers

Why You Shouldn't Respond to Voicemails from Unknown Callers

Although most people are aware being wary of phone calls from unknown numbers, the caller identification business Hiya has discovered a new scam call method that uses voicemail to encourage potential victims to call back.

This new scam strategy utilized by fraudsters begins with unclear voicemail messages left on a victim’s smartphone where an unknown voice is heard talking about them to another person.

Suppose a potential victim’s interest is sparked by someone in a voicemail stating, “I’m trying to get a hold of them right now,” and they decide to call back. In that case, the fraudsters on the other end of the line will attempt to steal their personal information or money by promising phony tax relief services.

The Eavesdropping Scam is particularly efficient because it escapes most call security systems by not displaying any regular scam call flags. Because of the ambiguity of the voicemail and the absence of any typical fraud-related terms, this scam has the potential to reach more victims. Still, happily, Hiya was able to intervene and halt it using the company’s Adaptive AI.

Thwarting the Eavesdropping Scam

Although the Eavesdropping Scam may avoid detection by other call protection systems, Hiya’s Adaptive AI enabled the firm to identify over 90% of these calls from the start.

The company’s Real-Time Intelligence Service allows its Adaptive AI to recognize new frauds based on their strategies, even during the first conversation. Phone numbers involved in the Eavesdropping Scam call were detected in fewer than 12 call attempts on average, and after successfully recognizing and reporting these calls, Hiya collaborated with a third-party service provider to shut down the original operation within 24 hours.

The company’s call protection service also uses the STIR/SHAKEN protocol to improve its capacity to detect scam calls and faked calls. However, the protocol demonstrates its limitations in the highly dynamic, ever-changing scam call ecology, which is why Hiya employs additional signals.

Hiya CEO Alex Algard explained in a press release how the company’s Adaptive AI was able to thwart the Eavesdropping Scam, saying:

“Catching this new and emerging scam tactic shows the power of Hiya’s Adaptive AI capabilities. Because our models are self-learning and focus on tactics, we can detect new scam risks in real-time and, in this case, shut down the operation before it reaches most users. At Hiya, our mission is to eradicate spam and fraud calls from the voice network fully, and the Eavesdropping Scam is the latest example of how we’re outsmarting scammers and protecting users.”
