Vishing (voice or VoIP phishing) is an electronic fraud tactic in which individuals are tricked into revealing critical financial or personal information to unauthorized entities. Vishing works like phishing but does not always occur over the Internet and is carried out using voice technology. A vishing attack can be conducted by voice email, VoIP (voice over IP), or landline or cellular telephone.

The potential victim receives a message, often generated by speech synthesis, indicating that suspicious activity has taken place in a credit card account, bank account, mortgage account or other financial service in their name. The victim is told to call a specific telephone number and provide information to "verify identity" or to "ensure that fraud does not occur." If the attack is carried out by telephone, caller ID spoofing can cause the victim's set to indicate a legitimate source, such as a bank or a government agency.

SMS and text messages have become a popular tool for phishing. Scammers use social engineering to scam people into providing information by creating a sense of urgency and a false pretext of legitimacy to trick people into providing personal information.

Do not provide personal information, especially passwords, or PIN through a text.

Do not open links through text messages and SMS.

A Trojan horse, or Trojan, is a type of malicious code or software that looks legitimate but can take control of your computer. A Trojan is designed to damage, disrupt, steal, or in general inflict some other harmful action on your data or network.

A Trojan acts like a bona fide application or file to trick you. It seeks to deceive you into loading and executing the malware on your device. Once installed, a Trojan can perform the action it was designed for.

Anytime you need to share confidential information about yourself, such as all of your contact information, your credit/bank account number (to make online payments), you should always make sure that the site is HTTPS. This will protect your information from being taken by hackers and used to steal your identity. If you want to make a purchase online and you notice that the site is not HTTPS, you should either phone in your order or physically go to the store.

By using a VPN (virtual private network) when you connect to a public Wi-Fi network, you'll effectively be using a 'private tunnel' that encrypts all of your data that passes through the network. This can help to prevent cybercriminals — that are lurking on the network — from intercepting your data.

Spear-phishing emails have improved within the past few years and are now extremely difficult to detect without prior knowledge on spear-phishing protection. Spear-phishing attackers target victims who put personal information on the internet.

Cybercrooks may be able to force mobiles to send premium-rate SMS messages or prevent them from receiving messages due to security weaknesses in mobile telecoms standards.

The weakness involves the handling of messages directed towards SIM Application Toolkits, applications preloaded onto SIM cards by mobile operators. The applications can be used for functions such as displaying available credit or checking voicemail, as well as handling value-added services, such as micro-payments.

Security researchers have found a way to bypass that limit on Visa cards. Their hack, which isn’t limited to U.K. cards, could let opportunistic crooks drain accounts with a single tap, and they claim they don’t even need to steal the credit card. And little on Visa’s side is being done to address this fresh fraud threat.
