What is Social Engineering

Social engineering is a manipulation technique that exploits human error to gain private information, access, or valuables. In cybercrime, these “human hacking” scams tend to lure unsuspecting users into exposing data, spreading malware infections, or giving access to restricted systems.

Know The Red Flags

Phishes are masters of making their content and interactions appealing. From content design to language, it can be difficult to discern whether content is genuine or a potential threat, which is why it is so important to know the red flags. Awkward and unusual formatting, overly explicit call outs to click a hyperlink or open an attachment, and subject lines that create a sense of urgency are all hallmarks that the content you received could be potentially from phish and indicate that it should be handled with caution.

Verify The Source

Phishing content comes in a variety of ways, however, many phishes will try to impersonate someone you may already know — such as a dean or a department chair or a colleague, or friend — as a way to trick you into believing their malicious content is actually trustworthy. Don’t fall for it. If you sense any red flags that something may be out of place or unusual, reach out directly to the individual to confirm whether the content is authentic and safe. If not, break-off communication immediately and flag the incident through the proper channels.

Be Aware

As more digital natives have come online and greater awareness has been spread about phishing, bad actors have begun to diversify their phishing efforts beyond traditional email. For example, voice phishing — or vishing — has become a primary alternative for bad actors looking to gain sensitive information from unsuspecting individuals. Similar to conventional phishing, vishing is typically executed by individuals posing as a legitimate organization — such as a healthcare provider or insurer — and asking for sensitive information. Simply put, it is imperative that individuals be wary of any sort of communication that asks for personal information whether it be via email, phone or chat — especially if the communication is unexpected. If anything seems suspicious, again, break-off the interaction immediately and contact the company directly to confirm the veracity of the communications.

What is Social Engineering

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 fool someone into giving you their password than it is for you to try hacking their password (unless the password is really weak).Security is all about knowing who and what to trust. It is important to know when and when not to take a person at their word and when the person you are communicating with is who they say they are. 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?Ask any security professional and they will tell you that the weakest link in the security chain is the human who accepts a person or scenario at face value. It doesn’t matter how many locks and deadbolts are on your doors and windows, or if have guard dogs, alarm systems, floodlights, fences with barbed wire, and armed security personnel; if you trust the person at the gate who says he is the pizza delivery guy 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?

It can definitely look like an email from a friend. If a 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 person’s contacts or leave messages on all their friend’s social pages, and possibly on the pages of the person’s friend’s friends.

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 so the criminal can take over your machine and collect your contacts info and deceive them just like you were deceived
• Contain a download of pictures, music, movie, document, etc., that has malicious software embedded. If you download–which you are likely to do since you think it is from your friend–you become infected. Now, the criminal has access to your machine, email account, social network accounts and contacts, and the attack spreads to everyone you know. And on, and on.

Emails from another trusted source such as the Dean or your Building Manager

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. 

Using a compelling story or pretext, these messages may:

• Urgently ask for your help. Your ’friend’ is stuck in country X, has been robbed, beaten, and is in the hospital. They need you to send money so they can get home and they tell you how to send 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, and you may also be asked to prove who you are often including your social security 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 Peer-to-Peer sites offering a download of something like a hot new movie, or music. But the schemes are also found on social networking sites, malicious websites you find through search results, and so on. Or, the scheme may show up as an amazingly great deal on classified sites, auction sites, etc.. To ally your suspicion, you can see the seller has a good rating (all planned and crafted ahead of time). 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 while also offering more help. 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. For example, even though you know you didn’t originally ask a question you probably a problem with your computer’s operating system and you seize on this opportunity to get it fixed. For free! The moment you respond you have bought the crook’s story, given them your trust and opened yourself up for exploitation. 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, or 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; these are often carried out by people you know and who are angry with you, but it is also done by nasty people just trying to wreak havoc, people who want to first create distrust in your mind about others so they can then step in as a hero and gain your trust, or by extortionists who want to manipulate information and then threaten you with disclosure. This form of social engineering often begins by gaining access to an email account or another communication account on an IM client, social network, chat, forum, etc. 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 they 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 phishing 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 sales 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.
