Social Engineering (main topic)
Social engineering is the art of manipulating people so they give up confidential information. The types of information cyber criminals are seeking can vary, but when individuals are targeted the criminals are usually trying to trick you into giving them your passwords or bank information, or access your computer to secretly install malicious software – that will give them access to your passwords and bank information as well as giving them control over your computer. Cyber criminals use social engineering tactics because it is usually easier to exploit your natural inclination to trust than it is to discover ways to hack your software. For example, it is much easier to dupe someone into giving you their password than it is for you to try hacking their password. Security is all about knowing who and what to trust. It is important affirm the person you are communicating with is who they say they are as it is to know when to take a person at their word. The same is true of online interactions and website usage: when do you trust that the website you are using is legitimate or is safe to provide your information? It doesn’t matter how many locks and deadbolts are on your doors and windows, if you trust the person at the gate and you let him in without first checking to see if he is legitimate you are completely exposed to whatever risk he represents.
What Does a Social Engineering Attack Look Like?
Email from a friend
If a cyber criminal manages to hack or socially engineer one person’s email password, they have access to that person’s contact list. And because most people use one password everywhere, they probably have access to that person’s social networking contacts as well. Once the criminal has that email account under their control, they send emails to all the victim’s contacts or leave messages on all the victim’s friend’s social pages, Taking advantage of your trust and curiosity, these messages will:
- Contain a link that you just have to check out–and because the link comes from a friend and you’re curious, you’ll trust the link and click–and be infected with malware. The criminal can then take over your computer and collect your contacts information, deceiving them just like you were deceived
- Contain a download of pictures, music, movie, document, etc., that has malicious software embedded. If you download you become infected. Now, the criminal has access to your computer, email account, social network accounts and contacts, and the attack spreads to everyone you know. And on, and on.
Email from another trusted source
Phishing attacks are a subset of social engineering strategy that imitate a trusted source and concoct a seemingly logical scenario for handing over login credentials or other sensitive personal data. Financial institutions represent the vast majority of impersonated companies. Social engineering attacks including phishing and pretexting (see below) are responsible for 93% of successful data breaches.
Using a compelling story or pretext, these messages may:
- Urgently ask for your help. Your ’friend’ is stuck in country X, has been robbed, injured, and is in the hospital. He/She needs you to send money so they can get home. They tell you how to send the money. In this case, you will be sending the money to the criminal.
- Use phishing attempts with a legitimate-seeming background. Typically, a phisher sends an e-mail, IM, comment, or text message that appears to come from a legitimate, popular company, bank, school, or institution.
- Ask you to donate to their charitable fundraiser, or some other cause.Likely with instructions on how to send the money to the criminal. Preying on kindness and generosity, these phishers ask for aid or support for whatever disaster, political campaign, or charity is momentarily top-of-mind.
- Present a problem that requires you to "verify" your information by clicking on the displayed link and providing information in their form. The link location may look very legitimate with all the right logos, and content (in fact, the criminals may have copied the exact format and content of the legitimate site). Because everything looks legitimate, you trust the email and the phony site and provide whatever information the crook is asking for. These types of phishing scams often include a warning of what will happen if you fail to act soon because criminals know that if they can get you to act before you think, you’re more likely to fall for their phishing attempt.
- Notify you that you’re a ’winner.’Maybe the email claims to be from a lottery, or a dead relative, or the millionth person to click on their site, etc. In order to give you your ’winnings’ you have to provide information about your bank routing so they know how to send it to you or give your address and phone number so they can send the prize. You may also be asked to prove who you are often including your identity card number. These are the ’greed phishes’ where even if the story pretext is thin, people want what is offered and fall for it by giving away their information, then having their bank account emptied, and identity stolen.
- Pose as a boss or coworker. It may ask for an update on an important, proprietary project your company is currently working on, for payment information pertaining to a company credit card, or some other inquiry masquerading as day-to-day business.
Baiting Scenarios
These social engineering schemes know that if you dangle something people want, many people will take the bait. These schemes are often found on sites offering a download of something like a hot new movie, or music. But the schemes can also be found on social networking sites or malicious websites you find through google search results. The scheme may also show up as an amazingly great deal on classified sites, auction sites, etc. People who take the bait may be infected with malicious software that can generate any number of new exploits against themselves and their contacts, may lose their money without receiving their purchased item, and, if they were foolish enough to pay with a check, may find their bank account empty.
Response to a question you never had
Criminals may pretend to be responding to your’ request for help’ from a company. They pick companies that millions of people use such as a software company or bank. If you don’t use the product or service, you will ignore the email, phone call, or message, but if you do happen to use the service, there is a good chance you will respond because you probably do want help with a problem. The representative, who is actually a criminal, will need to ’authenticate you’, have you log into ’their system’ or, have you log into your computer and either give them remote access to your computer so they can ’fix’ it for you. They may also tell you the commands so you can fix it yourself with their help–where some of the commands they tell you to enter will open a way for the criminal to get back into your computer later.
Creating distrust
Some social engineering is all about creating distrust, or starting conflicts. This is done by horrid people just trying to wreak havoc or extortionists who want to manipulate information and then threaten you with its disclosure. This form of social engineering often begins by gaining access to an email or social media account. They accomplish this either by hacking, social engineering, or simply guessing really weak passwords.
- The malicious person may then alter sensitive or private communications (including images and audio) using basic editing techniques and forwards these to other people to create drama, distrust, embarrassment, etc. They may make it look like it was accidentally sent, or appear like they are letting you know what is ’really’ going on.
- Alternatively, they may use the altered material to extort money either from the person they hacked or from the supposed recipient.
There are literally thousands of variations to social engineering attacks. The only limit to the number of ways cyber criminals can socially engineer users through this kind of exploit is the criminal’s imagination. And you may experience multiple forms of exploits in a single attack. Then the criminal is likely to sell your information to others so they too can run their exploits against you, your friends, your friends’ friends, and so on as criminals leverage people’s misplaced trust.
Don’t become a victim
While these attacks are rampant, short-lived, and need only a few users to take the bait for a successful campaign, there are methods for protecting yourself. Most don't require much more than simply paying attention to the details in front of you. Keep the following in mind to avoid being phished yourself.
Tips to Remember:
- Slow down. Spammers want you to act first and think later. If the message conveys a sense of urgency or uses high-pressure pitch tactics, be skeptical; never let their urgency influence your careful review.
- Research the facts. Be suspicious of any unsolicited messages. If the email looks like it is from a company you use, do your own research. Use a search engine to go to the real company’s site, or a phone directory to find their phone number.
- Don’t let a link be in control of where you land. Stay in control by finding the website yourself using a search engine to be sure you land where you intend to land. Hovering over links in email will show the actual URL at the bottom, but a good fake can still steer you wrong.
- Email hijacking is rampant. Hackers, spammers, and social engineers taking over control of people’s email accounts (and other communication accounts) has become rampant. Once they control an email account, they prey on the trust of the person’s contacts. Even when the sender appears to be someone you know, if you aren’t expecting an email with a link or attachment check with your friend before opening links or downloading.
- Beware of any download. If you don’t know the sender personally AND expect a file from them, downloading anything is a mistake.
- Foreign offers are fake. If you receive an email from a foreign lottery or sweepstakes, money from an unknown relative, or requests to transfer funds from a foreign country for a share of the money, it is guaranteed to be a scam.
Ways to Protect Yourself:
- Delete any request for financial information or passwords. If you get asked to reply to a message with personal information, it’s a scam.
- Reject requests for help or offers of help. Legitimate companies and organizations do not contact you to provide help. If you did not specifically request assistance from the sender, consider any offer to ’help’ restore credit scores, refinance a home, answer your question, etc., a scam. Similarly, if you receive a request for help from a charity or organization that you do not have a relationship with, delete it. To give, seek out reputable charitable organizations on your own to avoid falling for a scam.
- Set your spam filters to high. Every email program has spam filters. To find yours, look at your settings options, and set these to high–just remember to check your spam folder periodically to see if legitimate email has been accidentally trapped there. You can also search for a step-by-step guide to setting your spam filters by searching on the name of your email provider plus the phrase ’spam filters’.
- Secure your computing devices. Install anti-virus software, firewalls, email filters and keep these up-to-date. Set your operating system to automatically update, and if your smartphone doesn’t automatically update, manually update it whenever you receive a notice to do so. Use an anti-phishing tool offered by your web browser or third party to alert you to risks.
