Cyber security infographic vishing11/13/2023 To avoid this issue, consumers can hang up and then use a completely different phone to call a known number for the entity to confirm the problem. In this way, the fraudster hijacks the next call, spoofing a dial tone and impersonating the trusted entity. However, although the victim hangs up, the vishing caller does not, and the line stays open as the victim attempts to call out again. Vishing attackers may also call victims, and direct them to call a government agency, bank, or other trusted entity. They might also convince the victim to take any number of actions, like transferring money, changing a password, downloading malware, or some other harmful activity. Human fraudsters may persuade victims by posing as employees of legitimate entities such as ISPs, banks, tech support, or others and attempt to obtain personal information. This is the simplest form of vishing, but sometimes vishing scams are more sophisticated. They enter a bank account number or credit card number on the keypad, and possibly additional personal details, such as expiration date, security Personal Identification Number (PIN), and date of birth. The victim calls the number, and again hears automated instructions-probably what they expect from a bank. The message then instructs the victim to call the institution immediately, but at a specific phone number-typically the same number spoofed in the victim’s caller ID. The “recording” tells the victim about unusual activity on their bank account, or that their credit card has been frozen, for example. Typically, an automated recording plays when the victim answers the call, usually generated by a text-to-speech synthesizer or similar vishing tool. ![]() This allows them to succeed based on volume alone, in many cases. And deepfake audio can even fool many listeners into believing they are hearing a trusted source.Ī common vishing tactic is for the cyber attacker to configure a war dialer to call a list of phone numbers stolen from an institution or phone numbers in a given region. However, vishing attackers can now use automated systems (IVR), caller ID spoofing, and other VoIP features to make monitoring, tracing, and blocking their activities difficult. And even mobile phones are at least associated with known users. ![]() Each line is associated with a specific user, the person or business who pays the bill, and terminates in a known physical location. Traditionally, landline telephone services have been trustworthy. ![]() Or, in a more involved vishing call, a scammer might attempt to use social engineering to induce the victim to share financial information and personal information, such as passwords and account numbers, or convince them to download “software” that is actually malware. During a typical vishing attack, a scammer might place hundreds of calls using voice over IP technology and a war dialer, spoofing a bank’s caller ID to make the call seem to originate from a trusted source.
