Research from Pindrop Security has found a 30-percent rise in phone fraud attacks on enterprises and more than 86.2 million attacks per month on U.S. consumers.
The annual Phone Fraud Report said that large financial institutions’ call centers were exposed to an average of more than $9 million in potential fraud each year. Financial and retail institutions have seen an increase in phone fraud of more than 30 percent since 2013, with one in every 2,200 calls being fraudulent. This rate increases for retailers that sell popular, expensive products with a high resell rate. The report also indicates that credit card issuers receive the highest rate of fraud attempts, with one in every 900 calls being fraudulent.
“These attackers are sophisticated, using a variety of tactics, including automation, working in criminal rings and using both the phone and cyber channel to make tracking their actions more difficult,” said Matt Garland, vice president of research and head of Pindrop Security’s newly formed Pindrop Labs team, which analyzed the data behind the report. “As major data breaches such as Anthem and Target have occurred, attackers have found the phone channel to be the vulnerable underbelly for corporations and consumers, allowing them to monetize the breaches through social engineering and account takeovers.”
Other report findings include:
- On average, large financial institutions exposed more than $9m in funds to attackers last year. Exposure measures the value of accounts in which an attacker was able to authenticate to the account.
- Banks experience a fraud call rate of one in every 2,650 calls. Brokerages report slightly less, with only one in 3,000 calls being fraud.
- More than 86.2 million calls per month in the U.S. are phone scams, and 36 million of those calls can be traced to one of the 25 most common phone scams.
- Attackers use VoIP lines for 53 percent of their calls, compared to 7.8 percent of the general public using VoIP as a means for phone communication.
