Types Of Social Engineering Attacks
Hackers use different social engineering tactics to manipulate their target depending on how they implement the attack. For example, they may use email, web, phone, USB drives, or other means. So, here are the some of the social engineering tactics:
There are two major types of Social Engineering attack – remote or in-person.
1. Remote Attacks (Phishing)
Phishing is one of the most popular social engineering tactics attackers use to get sensitive information from their target. It’s usually via email, text messages and phone calls.
– Email Attacks
Attackers send a well-crafted email with a deceptive subject line to trick the recipient into believing the email is from a trusted source. The email may contain seemingly legitimate documents, logos, contact details or a link to a cloned website to trick their target. The attack aims to create a sense of urgency and immediate action from the user. For example, you may receive an email prompting a password change or invoice for payment, which sends the attacker information or money once submitted.
– Phone Call Attacks (Vishing)
A social engineer who attacks over the phone, often called “vishing” for voice phishing, usually pretends to be someone, e.g., an account holder, business partner, staff or a trusted provider of your organisation. They typically gather necessary background information before making the call to avoid suspicion.
– Spear Phishing
Spear Phishing has the highest success rate. For example, the attacker sends a personalised spear phishing email or calls the target based on their job title or technical skills. The attacker may pretend to be a colleague within the organisation or an IT consultant who coerces the target for confidential information. Spear phishing attacks require months of preparation, making them harder to detect.
Scareware manipulates users through fear by deceiving the target with notifications of a malware infection. It suggests the user buy or download a fake antivirus software to get rid of it. However, the antivirus is a potentially dangerous software that can steal your personal information once installed. It’s common to encounter this type of social engineering attack while browsing the internet or via email. Rogue security software and crypto miner lock are two of the most popular scareware tactics cybercriminals use.
2. In-Person/Onsite Attacks
In-person social engineering techniques are less common than remote attacks. Yet, they’re very effective because businesses usually focus on IT security, not physical threats.
– Shoulder Surfing
Shoulder surfing is a physical social engineering attack that uses direct observation techniques to steal information. The attacker stands beside someone and watches them enter their login credentials or PIN at an ATM.
Tailgating is another onsite social engineering technique used by attackers seeking entry to restricted areas where biometrics, RFID cards, or any electronic access control is present. The attacker waits for the perfect opportunity to walk in behind an authorised person or determines when the next scheduled maintenance may be and arrives dressed like one to get past the front desk successfully.
– Key Loggers
Hardware and network devices often need technical services, so hackers usually take this opportunity. They may impersonate a third-party onsite tech support and install a key logger on shared computer systems to obtain usernames and passwords. It provides the hacker with access rights to control the workstations remotely.
Baiting is the equivalent of a Trojan horse in social engineering. The attacker will leave a malware-infected flash drive in a public place, hoping someone will pick it up and plug it into their computers. Distributed USBs are usually labelled as “Confidential” or “Salary info” to entice the victim to use it, giving access rights to the hacker once opened. Hackers also use online baiting to attract their target with free goods in exchange for personal information.
