Identify Social Engineering AttacksCan you identify different types of social engineering attacks in the Security+ exam?
The Security+ exam expects you to to be able to analyze and differentiate different types of social engineering attacks, including shoulder surfing, dumpster diving, tailgating, impersonation, hoaxes, whaling, phishing, and vishing. You might even see a performance based question related to these types of attacks.
Social engineering is the practice of using social tactics to gain information. It’s often low-tech and encourages individuals to do something they wouldn’t normally do, or cause them to reveal some piece of information, such as their user credentials.
Some of the individual methods and techniques include:
- Flattery and conning
- Assuming a position of authority
- Encouraging someone to perform a risky action
- Encouraging someone to reveal sensitive information
- Impersonating someone, such as an authorized technician
- Tailgating or closely following authorized personnel without providing credentials
Performance Based QuestionsTopics such as identifying attacks are ideally suited for the new performance based questions on the CompTIA Security+ exam. Instead of answering a multiple choice question, you might need to identify an attack and match it to the most likely target. If you're unfamiliar with the new performance based questions, check out these blogs too:

Matching Attacks Practice QuestionThe following table includes three columns: attack methods, attack targets, and attack types. However, they are jumbled and not in the correct order.
Would you be able to rearrange the items in the table so that each attack method is matched to the appropriate attack target and attack type? Each attack method, attack target, and attack type is used only once so your solution needs to ensure that all choices are used.

Phishing and WhalingPhishing is the practice of sending e-mail to users with the purpose of tricking them into revealing personal information or clicking on a link. A phishing attack will often send the user to a malicious website that appears to the user as a legitimate site.
The classic example is where a user receives an e-mail that looks like it came from eBay, PayPal, a bank, or some other well-known company. The “phisher” doesn’t know if the recipient has an account at the company, just as a fisherman doesn’t know if any fish are in the water where he casts his line. However, if the attacker sends out enough e-mails, the odds are good that someone who receives the e-mail has an account.
Whaling is a form of spear phishing that attempts to target high-level executives.
As an example, attackers singled out as many as twenty thousand senior corporate executives in a fine-tuned whaling attack a few years ago. The e-mails looked like official subpoenas requiring the recipient to appear before a federal grand jury and included the executive’s full name and other details, such as their company name and phone number.
The e-mails also included a link for more details about the subpoena. If the executives clicked the link, it took them to a website that indicated they needed a browser add-on to read the document. If they approved this installation, they actually installed a keylogger and malware. The keylogger recorded all their keystrokes to a file, and the malware gave the attackers remote access to the executive’s systems.
Similar whale attacks have masqueraded as complaints from the Better Business Bureau or the Justice Department. Executives are sensitive to issues that may affect the company’s profit, and these attacks often get their attention. This blog also covers phishing, spear phishing, and whaling.
VishingVishing attacks use the phone system to trick users into giving up personal and financial information. It often uses Voice over IP (VoIP) technology and tries to trick the user, similar to how other phishing attacks try to trick the user. When the attacker uses VoIP, it can spoof the caller ID, making it appear as though the call came from a specific company.
In one form of a vishing attack, a person receives a phone message indicating they need to call about one of their credit cards, and the message provides a phone number. In another form, the person receives an e-mail with the same information.
If the person returns the call, an automated recording gives some vague excuse about a policy and then prompts the user to verify their identity. One by one, the recording prompts the user for information like name, birthday, Social Security number, credit card number, expiration date, and so on. Once the person provides the information, the recording indicates the account is verified. What really happened, though, is that the person just gave up some important data to a criminal.
RoguewareRogueware (or scareware) is a type of Trojan that masquerades as a free antivirus program. When a user visits a site, a message on the web page or a popup appears indicating it detected malicious software (malware) on the user’s system. The user is encouraged to download and install free antivirus software. Users that take the bait actually download and install malware.
After a user downloads it and starts a “system scan,” it will report that it has located malware and pop up an official looking warning. In reality, it doesn't scan for malware and will always reports bogus infections.
If users try to remove the threats, they are informed that this is only the trial version, and the trial version won’t remove any threats. However, for the small fee such as $79.95, users can unlock the full version to remove the threats. Many people pay. Panda security reported that criminals took in an average of $34 million a month in recent years. This blog also covers rogueware.
Matching Attacks Practice Question AnswerThe following table shows the attack methods, attack targets, and attack types in the correct order.
- Whaling is a targeted phishing email sent to CEOs and other senior executives.
- Vishing is a type of phishing attack using a phone.
- Rogueware is bogus antivirus software downloaded by unsuspecting users from a website.
