Social Engineering Attack
Social Engineering impersonates the original user by using Email, SMS, and Phone calls which are known as Phishing, Smishing, andΒ Vishing or shoulder surfing and dumpster diving. Social engineering is the technique that persuades to deceive the victim to obtain sensitive and confidential information. Social engineer uses communication skills and tools to make the victim trust the social engineer and, rather than scanning for vulnerability to exploit. Social engineering usually makes phone calls sends SMS or Email, Instant messaging, and some other communication system available on the internet for persuasion and tricks to deceive the victim to get them to trust the social engineer to obtain intended and targeted information.
Firstly, the attacker builds trust between the primary victim and the social engineer so that whatever actions during communication are trusted. Building a trusting relationship with the victim may lead to releasing sensitive and confidential information and gaining unauthorized access to the information system without detection.

Human-Based Social Engineering: Human-based social engineering is person-to-person communication initiated by SMS or phone call to obtain intended information. Social engineers can impersonate an organization’s employee or technical support personnel of the same company; posting as one a current and valid employee of an organization. A social engineer can also carry out attacks on the company’s customers by posting as a customer service, support, or security technician. Shoulder surfing is a criminal technique used to steal confidential information by standing behind and watching over a victim’s shoulder when the victim logs into the account. Dumpster diving refers to searching in the trash bin to find useful information. Going through the victim’s trash can also be helpful, searching in a trash bin to recover written documents, used Tapes /CDsD, expired ID proof or credit cards, etc. Using this technique can be helpful to recover and gather some useful information.
Computer-Based Social Engineering: Computer-based social engineering refers to the use of computer and internet services that are not limited to Email or Instant messaging for persuasion to deceive the user to release target information. The social engineers may send a spoofed email or fake security issue or notification email stating ‘We notice unusual activity on your account, it is advisable to change your password, click this link to change your password now.’ A similar message is usually sent by a social engineer to steal a password by clicking the link that directs the victim to a page to enter the current password and then a new password. A social engineer can also send an email persuading a victim to download a file that may happen to be a harmful program like a virus, worm, or Trojan.
Social engineering is an act of exploiting the trust of people, which is not easy to doubt during communication. Every organization or service provider must have a support or customer service team to seek assistance or report issues, a computer or service user needs to verify once or twice by returning or directing communicated issues to technical support in the same organization or the service provider before responding or releasing information. The lack of security concerns of individuals has caused many organizations a huge financial loss.
To protect against social engineering attacks, individuals and organizations should adopt a combination of awareness, education, and security measures.
Here are some key strategies:
- User Awareness and Training:
- Educate individuals about the different types of social engineering attacks, including phishing, pretexting, baiting, and quid pro quo. Provide regular training sessions to raise awareness.
- Verify Requests:
- Encourage a healthy skepticism and promote a culture of verifying requests, especially those involving sensitive information or financial transactions. Verify through a separate communication channel.
- Use Multi-Factor Authentication (MFA):
- Implement MFA to add an extra layer of security, even if attackers manage to obtain login credentials through social engineering.
- Secure Personal Information:
- Instruct employees not to share sensitive information over the phone, email, or other communication channels unless they have verified the legitimacy of the request.
- Email Security:
- Implement email filtering solutions to detect and block phishing emails.
- Train users to recognize suspicious emails, including unexpected attachments, urgent requests, and unusual sender addresses.
- Use Strong Passwords:
- Encourage the use of strong, unique passwords and discourage password sharing.
- Regularly update passwords, especially after potential security incidents.
- Secure Physical Access:
- Control physical access to sensitive areas and information. Be cautious about allowing strangers into secure areas without proper authentication.
- Incident Response Plan:
- Develop and regularly update an incident response plan that includes procedures for handling social engineering incidents.
- Employee Reporting Mechanism:
- Establish a clear and confidential mechanism for employees to report suspicious activities or potential social engineering attempts.
- Limit Access Permissions:
- Restrict access permissions to sensitive information. Only grant access to individuals who require it for their roles.
- Regular Security Audits:
- Conduct regular security audits to identify and address vulnerabilities in systems and procedures that could be exploited through social engineering.
- Monitor Social Media Presence:
- Be cautious about the information shared on social media platforms. Attackers often gather information from public profiles to craft convincing social engineering attempts.
- Security Policies and Procedures:
- Develop and enforce strong security policies and procedures, covering areas such as information sharing, access controls, and incident reporting.
- Use Security Software:
- Implement security software that includes anti-malware, anti-phishing, and intrusion detection features.
- Regularly Update Software:
- Keep all software, including operating systems and security tools, up-to-date to patch vulnerabilities.
- Vendor and Third-Party Verification:
- Verify the identity of vendors or third parties before sharing sensitive information or granting access.
- Continuous Security Training:
- Social engineering tactics evolve, so continuous training is essential to keep employees informed about new threats and attack techniques.
By combining these measures, organizations and individuals can build a stronger defense against social engineering attacks. It’s important to foster a security-conscious culture and stay informed about emerging threats in the ever-evolving landscape of social engineering.
