Social Engineering: How Cybercriminals Exploit Human Behavior in Cyber Attacks
31 July, 2023
As technology continues to transform the African landscape, the digital world opens new opportunities and challenges for individuals and businesses. Among these challenges is the increasing threat of social engineering attacks – a sophisticated form of cyber attack that preys on human vulnerabilities instead of the machine or network.
It may interest you to know that, social engineering rank no 1 of the top attack type in 2022. This should signal the level of attention that should be given to this type of attack, yet when people discuss hacking and cyber security matters they tend to think more along the line of networks and devices ignoring the human factor which is really the weakest link.
In this blog post, we delve into the world of social engineering, examining how hackers exploit human behavior in cyber attacks. With a focus on the African context, we aim to raise awareness and empower individuals and businesses to stay cyber-savvy in the face of these evolving threats.
Social engineering is a form of cyber attack that exploits human behavior and psychological manipulation to deceive individuals into revealing sensitive information, performing certain actions, or granting unauthorized access to secure systems. Unlike traditional hacking methods that rely on technical vulnerabilities, social engineering targets the human element, making it a potent and pervasive threat in the cybersecurity landscape.
Social engineering attacks often take advantage of human emotions and cognitive biases to achieve their malicious objectives.
Social engineering exploits fundamental aspects of human behavior, including trust, curiosity, fear, urgency, and the desire to help others. Cybercriminals use these emotions to manipulate victims and gain unauthorized access to sensitive information or systems.
Common Types of Social Engineering Attacks:
Phishing: Phishing is one of the most prevalent social engineering attacks. In phishing attacks, cybercriminals send deceptive emails, and messages, or create fake websites that closely resemble legitimate ones. They aim to trick recipients into divulging sensitive information, such as login credentials, financial details, or personal data. Phishing attacks often play on emotions like fear or urgency to prompt quick action from the victim.
Pretexting: Pretexting involves creating a fabricated scenario to gain the victim’s trust and extract information. The attacker might pose as someone with authority or a trustworthy entity, such as an IT support technician, a government official, or a colleague. Through this fabricated pretext, they manipulate the victim into sharing confidential information or performing specific actions that compromise security.
Baiting: Baiting attacks lure victims with enticing offers or rewards. Cybercriminals might use attractive incentives like free software downloads, music, movies, or gift cards to entice individuals to click on malicious links or download infected files. Once the bait is taken, malware is delivered to the victim’s device, compromising security and potentially stealing sensitive data.
Spear Phishing: Spear phishing is a targeted social engineering attack aimed at specific individuals or organizations. Attackers conduct extensive research on their targets, gathering information from various sources like social media profiles, press releases, or company websites. Armed with this knowledge, they craft personalized messages that appear genuine, increasing the likelihood of success in deceiving the target.
Tailgating (Piggybacking): Tailgating, also known as piggybacking, involves gaining unauthorized physical access to a secure area by following an authorized person. Cybercriminals exploit the goodwill or courtesy of employees or visitors to enter restricted areas without proper authorization, bypassing physical security measures.
Quizzes and Surveys: In this type of social engineering attack, cybercriminals use quizzes or surveys that prompt users to answer seemingly innocent questions. These quizzes may be shared through social media or email and are designed to collect personal information that can be used for identity theft or other malicious activities.
Tech Support Scams: In tech support scams, attackers pose as technical support representatives from reputable companies or organizations. They contact individuals via phone calls or pop-up messages, claiming there is a technical issue with their computer or device. The scammer then convinces the victim to grant remote access to their system or provide sensitive information, leading to potential data theft or financial loss.
Awareness and education are essential in mitigating the risks posed by social engineering attacks. Being cautious of unsolicited communications, verifying the authenticity of requests, and staying informed about the latest social engineering tactics are crucial steps in protecting against these manipulative cyber threats.
The Psychology Behind Social Engineering
Social engineering attacks are effective because they exploit the fundamental aspects of human psychology and behavior. Cybercriminals leverage various psychological techniques to manipulate individuals into revealing sensitive information, performing certain actions, or granting unauthorized access. Understanding the psychology behind social engineering is crucial in recognizing and defending against these deceptive tactics. Here are some key psychological principles that cybercriminals use in social engineering attacks:
Trust and Authority: Social engineers often impersonate individuals or organizations that people trust or perceive as authoritative. By posing as a trusted figure, such as a colleague, manager, IT support personnel, or government official, attackers gain the victim’s confidence and increase the likelihood of compliance with their requests.
Fear and Urgency: Fear and urgency are powerful emotions that social engineers exploit to create a sense of panic or crisis. Attackers may use scare tactics, such as threatening account closures, fines, or legal action, to pressure victims into immediate action without taking the time to verify the situation.
Curiosity and Clickbait: Curiosity is a natural human instinct, and social engineers capitalize on it by creating enticing clickbait. They lure individuals with intriguing offers, sensational headlines, or fake news stories, leading them to click on malicious links or download infected files.
Reciprocity: The principle of reciprocity plays a role in social engineering attacks. Attackers might offer something to the victim, such as a free software download or a gift, creating a sense of indebtedness. This reciprocity motivates the victim to comply with the attacker’s request in return.
Social Norms: Social engineers exploit social norms to influence behavior. For example, they may create a sense of belonging or group pressure by stating that “many others have already taken this action” to convince victims to follow suit.
Overconfidence and Complacency: Social engineering attacks often succeed because people tend to overestimate their ability to detect deception. This overconfidence can lead individuals to let their guard down, making them vulnerable to manipulation.
Information Overload: Social engineers bombard their targets with excessive information, overwhelming their decision-making capabilities. In such cases, victims might not thoroughly assess the situation, making it easier for attackers to exploit their cognitive load.
Consistency and Commitment: Once individuals commit to a particular course of action, they tend to remain consistent with that commitment. Social engineers capitalize on this principle by gradually escalating their requests, starting with seemingly harmless actions and gradually leading to more significant demands.
Understanding the psychology behind social engineering is key to recognizing and thwarting these deceptive cyber attacks.
Real-Life Examples of Social Engineering Attacks
The “Nigerian Prince” Scam: One of the most infamous social engineering scams is the “Nigerian Prince” or “419” scam. In this classic email scam, cybercriminals pose as wealthy individuals from Nigeria or other countries, claiming they need help to transfer a significant sum of money out of the country. They promise the victim a substantial reward for assisting them. To proceed, the victim is asked to provide their bank account details or make upfront payments for various fees. In reality, there is no fortune, and scammers use the victim’s information for identity theft or further fraudulent activities.
Targeted Spear Phishing Attack on Gmail: In 2017, a sophisticated spear phishing attack targeted Google’s Gmail service. The attackers sent personalized emails to numerous Gmail users, including high-profile individuals like journalists, government officials, and activists. The emails contained malicious links disguised as legitimate Google Docs invitations. When recipients clicked on the link, they were redirected to a fake login page, tricking them into entering their Gmail credentials. This allowed the attackers to gain unauthorized access to their accounts and potentially access sensitive information.
The Equifax Data Breach: In 2017, Equifax, a major credit reporting agency, suffered a massive data breach that exposed the personal information of over 147 million individuals. The breach occurred due to a social engineering attack through a vulnerability in the company’s website software. Attackers exploited this weakness to gain unauthorized access to Equifax’s systems and extract sensitive customer data, including Social Security numbers, addresses, and credit card information.
The Bangladesh Bank Heist: In 2016, cybercriminals orchestrated a sophisticated social engineering attack targeting Bangladesh Bank. The attackers used malware to infiltrate the bank’s computer systems and gained access to the bank’s SWIFT financial messaging network. They then sent fraudulent transfer requests totaling hundreds of millions of dollars to accounts in the Philippines. Although some of the transfers were blocked, the attackers successfully stole $81 million, highlighting the impact of social engineering on financial institutions.
The Twitter Bitcoin Scam: In July 2020, attackers compromised several high-profile Twitter accounts, including those of celebrities, politicians, and companies. They posted tweets asking followers to send Bitcoin to a specified address, with the promise of doubling the amount in return. The tweets were part of a social engineering scheme aimed at defrauding users into sending money to the attackers’ Bitcoin wallet. The incident raised concerns about the vulnerability of prominent social media accounts to social engineering attacks.
Real-life examples of social engineering attacks demonstrate the craftiness and adaptability of cybercriminals in exploiting human vulnerabilities. These incidents underscore the importance of cybersecurity awareness and education for individuals and organizations alike.
