    When people are thinking about common vectors for cybercrimes, a voice phone call might not come to mind. However, over the last decades, criminals have found it increasingly profitable to gain information over the phone. Vishing, or voice phishing, is when a cybercriminal uses the phone to gain sensitive information from the recipient as part of a larger cyberattack. Here’s what you need to know to keep yourself safe from vishing attacks in 2024.

      What is vishing?

      Here is a simple definition of vishing. 

      Vishing definition: Vishing (voice phishing), sometimes referred to as a phone scam, is when cybercriminals use phone calls to gain sensitive information from the recipient as part of a cyberattack. 

      What is the goal of vishing attacks?

      Ultimately, vishing attacks like most cyberattacks, are about gaining money from the victim. This can be done directly, by getting the person on the phone to transfer money during that phone call or subsequent ones, often using cryptocurrencies or gift cards to make it harder to reverse and track the payments. 

      However, for businesses, vishing attacks are often designed to get more money indirectly, by getting sensitive information, such as usernames and passwords, to further a larger sophisticated attack. 

      For example, vishing is often part of a ransomware attack.

      Vishing example 

      If you search news sites for vishing examples, you’ll find dozens. Many of them are long-running scams that target the elderly and gain a few hundred to thousands of dollars per victim. However, the total gained can reach the millions as these scams are hard to investigate and easy to scale. 

      While less common, vishing attacks also threaten business, and the total dollar value of a single attack can easily exceed millions of dollars. Caesars and MGM, two Las Vegas casinos, were attacked using vishing and spear phishing techniques together. 

      Criminals used information found on LinkedIn to impersonate employees on the phone with the IT department. Then, they used the new credentials provided by IT to break into their systems and install ransomware. 

      The results were devastating. MGM saw their cash flow drop by 10-20% and market capitalization decrease by $2 billion during the 10 days they were unable to operate. 

      Caesars, unlike MGM, decided to pay a reported $15 million to the ransomware-as-a-service hackers. Indeed, if you allow the vishing scheme to get to the point where ransomware has been installed on your business’s system, then paying the ransom is often the most economical route.

      Vishing statistics

      Phone scams have been around for decades, but the nature of these schemes has changed dramatically in the last decade. Criminals are now able to “spoof” local phone numbers, even your grandchild or coworker’s phone number, to make their pitches seem more authentic. 

      In addition, they can use information publicly available on Linkedin to further benefit their case. These tools combined with lots of practice have made it very hard for even IT professionals to recognize a visher. 

      That’s why about one third of all Americans have fallen victim to a phone scam at some point. All of these attacks combined have pushed the economic cost higher, from $29.8 billion in 2021 to $39.5 billion in 2022. 

      Around 300,000 to 400,000 vishing phone calls were recorded daily in America in 2022. Despite this, only 30% of professionals were familiar with the term “vishing” in 2022, up from 25% in 2019. 

      Vishing represents the third most popular vector for cyberattacks on businesses, with the average loss from a successful attack reaching $10.1 million.

      Common vishing tactics

      According to the Federal Trade Commission (FTC), “There is no prize… You won’t be arrested… You don’t need to decide now… Only scammers demand you pay certain ways… [and] Government agencies won’t call to confirm your sensitive information.” 

      That’s a pretty good summary of common vishing tactics. Basically, they use the same tools as marketers to make you feel like you need to make a decision now and the stakes are high enough that you should listen to the visher instead of your gut.

      Here are some common specific vishing strategies:

      How do you prevent vishing attacks? 

      No vishing attack can succeed if you do three things: slow down, hang up, and call back. 

      1. Hang up: If you have even the slightest feeling something is a scam, then it’s almost definitely a scam. Simply hang up. If the call was legitimate, then you can find out during Step 3.

      2. Call back: If someone from the Bank of America calls you, then you can always hang up, find the number online, and call that number to ask about your account. If the issue was legitimate, then they’ll know about it. Otherwise, pat yourself on the back for dodging a scam. 

      As an IT leader, you should equip your team with the knowledge and tools they need to avoid vishing scams. 

      1. Knowledge: A paltry 30% of Americans know the term vishing. While many more probably have a general idea of what phone scams are, they might not be aware of just how sophisticated they can be. You should be informing them of the pitfalls and how to protect the business from this major threat.

      2. Tools: There are many types of software available to protect employees from vishing attacks. Foremost among the tools needed is a way to protect your most sensitive information. TeamPassword is the best password manager for teams. When your employees don’t need to know the credentials to share them, they can’t accidentally share them with hackers.
