Social Engineering / Hacking Your Mind

Hacking Your Mind
Cyber criminals have learned that the easiest way to take control of your computer or
steal your information is to simply ask. Use common sense. If a person or a message
seems suspicious or too good to be true, it may be an attack.

The Attack
Today, much of your interaction with other people is done virtually; you no longer need to be  in physical contact to communicate. You talk to people on the phone, chat with them via instant messaging, send SMS messages on your smartphone or communicate with email. These technologies have made it much easier to communicate and work with people from
around the world. However, these technologies also make it much easier for cyber criminals to launch one of their most effective attacks against you: social engineering.

Social engineering is not a technical attack, meaning it does not exploit vulnerabilities in your computer. Instead, it is a psychological attack that exploits vulnerabilities in you. Cyber criminals build trust by pretending to be a person or organization you know. They then exploit this trust to obtain whatever they want, such as access to your computer, your money or your information. Cyber criminals have learned that often the easiest way to steal something is to
simply ask for it. Social engineering attacks use the same tools you use every day, including email, smartphones and the web.

Protecting Yourself
Social engineering attacks are the hardest to protect against because technology alone cannot solve the problem. You are the best defense. Understand that you are a target and that cyber criminals will use any technique they can to fool or trick you. The simplest way to protect yourself is to use common sense. If an email, message on Facebook or phone call seems suspicious or sounds too good to be true, it is most likely an attack. Below are several common social engineering attacks.

Malicious Email
You receive an email from your bank saying that your account has been locked for security reasons. You must log into your account and reset it right away or you will be permanently locked out. The email then provides a link for you to click on. If you click on the link you are taken to a website that looks just like your bank. However, in reality this is a fake website controlled by the hackers, whose goal is to harvest your username and password when you log in. In some cases, instead of sending you to a website to steal your username and password, they send you to a website that will automatically hack into and infect your computer. The best way to protect yourself is not to click on any links in emails you were not expecting. If you are  concerned that the email may be legitimate, open your browser, type in the URL to your bank yourself and then log in instead of clicking on the link. That way you know for sure you are connected to your real bank.

Scams
You receive a text message on your smartphone announcing you have won the lottery. To collect your lottery winnings you must contact a person and provide them your banking information. When you contact the person they explain that to receive your lottery winnings you must first pay a transaction fee or taxes. Once you provide your information and pay the fees, the cyber criminals disappear with your money and information, never to be seen again. The simplest way to protect yourself is simply ignore and delete the email.

Facebook
Your friend posts on her Facebook page that she is on vacation in London and has just been mugged. She needs someone to send her money right away so she can get back home. However, this is a lie; your friend is not really on vacation, nor has she been mugged. Instead a cyber criminal has hacked into her Facebook account, then posted this fake message in an attempt to scam money from her friends, such as you. In this case, the best way to protect yourself would be to call your friend on the phone and confirm if she needs help.

Tech Support Scam
You receive a phone call from someone claiming to be from a computer support company. They believe your computer is infected and have been tasked to investigate and help you secure your computer. They then ask you if there are specific files on your computer and tell you how to find them. When you locate the files on your computer the caller confirms your computer is infected. In reality this is all a lie, your computer is not infected, these files are standard files that every computer has.

Once they have you fooled into believing your computer is infected they will then pressure you into buying their security software. However, this software is really a virus that gives them total control of your computer. In the end, not only has the caller tricked you into infecting your computer for them, but you just paid them to do it.

    Thanks for the heads up! With all these schemes going around, it helps to be skeptical. When in doubt, take time to research on deals, especially those made online, before you get involved. Take advantage of the free reverse phone number look-up service at Callercenter.com too! The website does not only provide accurate information on the phone number, but it also developed a free call blocker app to help filter incoming calls. And lastly, in the event of getting a scam call, make sure to report it to the proper authorities.
