Social Engineering Attack Life Cycle: The Art of Human Hacking

In the beginning, social engineering was an art of social science. It is used to change people’s behaviour and make changes in society. It looks at a lot of groups, including government, media, academia and industries.

Nevertheless, with the development of technology and people’s concerns about security, social engineering has started to be used. Cyber criminals use it to trick humans by using deceptive techniques or information that disguises their intentions. Now, social engineering is an active element of the attack layout of cyber attacks. Whether insider threats, spear-phishing, smashing, or vishing – all of these attacks involve social engineering element as a starting factor.

What is social engineering in cyber security?

The definition of social engineering is explained as exploiting human psychology to manipulate people and influence them into performing actions or divulging confidential information. It is often used as a social science concept in psychological warfare or computer security, and it can be highly effective. Corporations spend millions on prevention mechanisms because they know how devastating it can be when social engineers compromise their assets.

So, social engineering is the art of three things?

Manipulating
Influencing
Deceiving

Social engineering is an effective means of cyber attack that potential threat actors and competent malicious social attackers apply to their target to obtain their desirable access, data, or assets. Depending upon the attacker’s goal, the objectives may vary; however, generally, these attacks’ primary targets are employees, colleagues, friends, or often the business owner and the board members.

Attack lifecycle

The attack lifecycle is a systematic process that an attacker follows in order to successfully carry out a cyber attack. This process can be broken down into several stages:

Research and Information Gathering: Attackers gather information about their target, such as their name, job title, email address, phone number, and social media profiles.
Developing a False Identity: The attacker creates a false identity to use in the attack, such as a fake email address, phone number, or social media account.
Building Trust: The attacker builds trust with the target by offering help or asking for assistance with a plausible scenario.
Manipulation: Once the attacker has gained the target’s trust, they manipulate the target into divulging sensitive information or performing actions that compromise their security.
Execution: The attacker uses the information they have gathered to carry out the attack, such as theft of sensitive information or unauthorized access to systems.

These five steps make up the social engineering attack life cycle, which can be used to compromise individuals and organizations. It is important to be aware of these tactics and to take steps to protect against social engineering attacks.

This cycle is not always linear and may repeat itself multiple times. It is important for organizations to be aware of the attack lifecycle and take measures to detect and prevent cyber attacks at each stage.

The attack practice of social engineering happens in a few phases. The cyber criminals initially investigate the target to find out the necessary information to identify potential weak points, missing security controls, vulnerable protocols, etc. That could later help them prepare social engineering tactics before proceeding with the actual social engineering attack.

Afterwards, the criminals move further to prepare the attack plan through various social engineering tactics that likely help them gain the victim’s trust and facilitate breaking into the security mechanism. Generally, victims are targeted through calls, online activities, and often time in-person to assist in gaining or escalating privileges and disclosing sensitive information such as personal identifiable information (PII), financial information, etc. The attacker does not rely upon a single source to gather information; he/she approaches another staff or authority of the targeted organization to collect more data and add credibility to the information provided by the first source.

What are the impacts of Social Engineering?

Social engineering attacks can have a significant impact on both individuals and organizations. These attacks can result in the theft of sensitive information, such as login credentials, financial information, and personal information. This information can be used for identity theft, financial fraud, and other malicious activities. Social engineering attacks can also compromise the security of systems and networks, allowing attackers to gain access to confidential information and carry out further attacks.

A successful social engineering attack results in an attacker gaining authorised and authentic access to the target’s system. Once the attacker has open access as of the employee or individual, he/she can infiltrate the system, network, or data with their malicious activities or even exfiltrate the data. This data exfiltration leads the business compromise and becomes the cause of data theft, data leakage, modification. In addition to it, in worse cases, it sometimes drives to ransomware.

Currently, most businesses are aware of the negative effect and possible consequences of successful cyber attacks on the company or organisation. They are often unaware of how severe an impact any social engineering attack can hold on the business in both short and long-term scenarios.

Short term effects on business:

Short-term effects on businesses from social engineering attacks can include:

Financial Loss: Organizations may incur direct financial losses from theft of sensitive information or unauthorized access to systems. They may also face costs from remediation efforts and compensation for victims of the attack.
Reputation Damage: A successful social engineering attack can damage an organization’s reputation and cause customers and stakeholders to lose trust in the security of their information.
Productivity Loss: Businesses may experience a loss of productivity as employees work to mitigate the effects of the attack and restore normal operations.
Legal Liability: Organizations may face legal liabilities if sensitive information is compromised, or if they fail to meet regulatory compliance requirements.
Decreased Employee Morale: Employees may feel violated and lose confidence in their ability to protect sensitive information, leading to decreased morale and motivation.

In conclusion, social engineering attacks can have significant short-term effects on businesses, leading to financial losses, reputation damage, decreased productivity, legal liabilities, and decreased employee morale. It is important for organizations to take steps to protect against these types of attacks.

Long term effects on business:

The long-term effects of social engineering on any business type are more long-lasting and not apparent than the short-term impact.

After a successful social engineering attack, if the attacker has gotten his hands on the customer data or any personal information, the customer trust and reputational damage must occur. Additionally, in this situation, it impacts the organisation to fulfil the legal requirements and lawsuits in penalties that vary from €20 million (about £18 million) to 4% of annual global turnover. This gets more severe in large amounts of data theft that takes a year to regain the reputation and customer trust and settle down the lawsuits.

Similarly, in the earlier mentioned case of a ransomware attack, the short-term impact can turn into the long-term effect if the attacker has gotten access to another network or infrastructure and plans to maintain his foothold or install a backdoor and C2C server to steal or spy on organisation activities. It is especially beneficial in the case of supply chain attacks. The advanced threat attackers choose to hide their identity after gaining access to the network and complete their suspicious mission while remaining in the environment for months and sometimes for years.

Lastly, in the cause of frequent successful social engineering attempts, the clients and customers may not like to risk their data privacy and continue the business with such that does not hold a good reputation. This would likely result in benefiting the competitor with potential customers.

What are the types of social engineering?

Generally, the attacker uses open-source intelligence (OSINT), which includes publically available information collected from the company website, social and shared networks, forums, newspapers, etc. It helps them identify the potential staff or victim from the targeted organisation to prepare a plan for the initial attacks to extract sensitive information and further access points. Social engineering attacks are carried out via many different techniques and can be performed anywhere where human interaction is involved.

It includes targeting the victim through the digital sphere as well as in the physical arena. The most effective and common types of social engineering attack are:

1. Phishing

Phishing is the most common type of social engineering attack, typically using spoofed email addresses and links to trick people into providing login credentials, credit card numbers, or other personal information. Variations of phishing attacks include:

Angler phishing – using spoofed customer service accounts on social media
Spear phishing – phishing attacks that target specific organizations or individuals

2. Whaling

Whaling is another common variation of phishing that specifically targets top-level business executives and the heads of government agencies. Whaling attacks usually spoof the email addresses of other high-ranking people in the company or agency and contain urgent messaging about a fake emergency or time-sensitive opportunity. Successful whaling attacks can expose a lot of confidential, sensitive information due to the high-level network access these executives and directors have.

3. Diversion Theft

In an old-school diversion theft scheme, the thief persuades a delivery driver or courier to travel to the wrong location or hand off a parcel to someone other than the intended recipient. In an online diversion theft scheme, a thief steals sensitive data by tricking the victim into sending it to or sharing it with the wrong person. The thief often accomplishes this by spoofing the email address of someone in the victim’s company—an auditing firm or a financial institution, for example.

4. Baiting

Baiting is a type of social engineering attack that lures victims into providing sensitive information or credentials by promising something of value for free. For example, the victim receives an email that promises a free gift card if they click a link to take a survey. The link might redirect them to a spoofed Office 365 login page that captures their email address and password and sends them to a malicious actor.

5. Honey Trap

In a honey trap attack, the perpetrator pretends to be romantically or sexually interested in the victim and lures them into an online relationship. The attacker then persuades the victim to reveal confidential information or pay them large sums of money.

6. Pretexting

Pretexting is a fairly sophisticated type of social engineering attack in which a scammer creates a pretext or fabricated scenario—pretending to be an IRS auditor, for example—to con someone into providing sensitive personal or financial information, such as their social security number. In this type of attack, someone can also physically acquire access to your data by pretending to be a vendor, delivery driver, or contractor to gain your staff’s trust.

7. SMS Phishing

SMS phishing is becoming a much larger problem as more organizations embrace texting as a primary method of communication. In one method of SMS phishing, scammers send text messages that spoof multi-factor authentication requests and redirect victims to malicious web pages that collect their credentials or install malware on their phones.

8. Scareware

Scareware is a form of social engineering in which a scammer inserts malicious code into a webpage that causes pop-up windows with flashing colors and alarming sounds to appear. These pop-up windows will falsely alert you to a virus that’s been installed on your system. You’ll be told to purchase and download their security software, and the scammers will either steal your credit card information, install real viruses on your system, or (most likely) both.

9. Tailgating/Piggybacking

Tailgating, also known as piggybacking, is a social engineering tactic in which an attacker physically follows someone into a secure or restricted area. Sometimes the scammer will pretend they forgot their access card, or they’ll engage someone in an animated conversation on their way into the area so their lack of authorized identification goes unnoticed.

10. Watering Hole

In a watering hole attack, a hacker infects a legitimate website that their targets are known to visit. Then, when their chosen victims log into the site, the hacker either captures their credentials and uses them to breach the target’s network, or they install a backdoor trojan to access the network.

11. Quid Pro Quo

The other form of social engineering attack involves the quid pro quo technique. Contrary to the baiting, quid pro quo relies on a mutual exchange; it could be a credential exchange for money or solving any issue and any service. Most of the time, the attacker targets the IT or technical support individuals by impersonating a security researcher or a technical person of any organisation offering free services or materialistic things in exchange. They often trick the target into switching off the security controls (turning off the anti-virus, anti-phishing solution, allowing them physical access to any data centre, system, etc.) to download malware or extract information.

12. Shoulder Surfing

This social engineering method involves simple techniques to get login credentials or other interesting information by watching over someone’s screen through passing by or looking over someone’s shoulders or behind either memorising it or writing it down.

Is phishing social engineering?

Phishing is one of the most common techniques used by social engineers to lure victims into giving away confidential information, access, or click over the malicious link.

Phishing vs social engineering

Social engineering is a broad domain in cyber security that relies on human hacking instead of exploiting technical, software, or code flaws. Phishing is one of the tactics used in the social engineering domain. Phishing involves subconscious manipulation through explicit emails encoded with suspicious attachments or web URLs [link] and targeted emotional email content with a sense of urgency to commit security mistakes or give out valuable data.

What are examples of social engineering techniques?

Human emotions are wild, and they can both make or break anything, which benefits the most social engineer attackers. Social engineering has always been the most loved tool of the ill-intentioned attackers, and they have been doing this for ages.

Here are some examples of social engineering attacks used repeatedly by attackers to gain access and benefits in terms of finance, access point, etc., or commit the different types of a cyber attack.

Urgency

Grabbing human attention with a sense of urgency is the most used case in the social engineering attack. Often attackers hit their target to perform urgent action, and they craft the scenario and email tone that presents the urgency and need to act quickly.

In 2016 the world witnessed a great example of a phishing attack when the Democratic National Convention employees fell for a spear-phishing attack. The hacker prepared and sent an email that occurred to the victim as Google sent it to rest the password. Since the email has a clickable link to reset the password and the content shows malicious activity going on the subject’s email account. This phishing attempt successfully tricked the people into changing their account’s password to stop the action urgently. People started believing in the provided information, resulting in granting access to their accounts.

The other social engineering attempt was made on one of the cyber security companies named RSA SecurID in 2011 when the phishing email was sent out to some employees with an excel document attachment claiming another company’s recruitment plan. When employees opened the excel document, they exploited the flash vulnerability and installed the infected system’s back door. This minor negligence caused the company to pay a penalty of $66 million.

Similarly, in 2014 one of the internet giants of that time, Yahoo, had become the victim of social engineering through a simple spear phishing attack targeting the company’s semi-privileged staff. The tricked employee came under the fraudster attempt and accessed the attacker he used to download the yahoo user and customer database.

In 2017, the Yahoo breach affected 3 billion user accounts placed over the dark web on the sale at $350 million.

Greed

The human emotion of greed convinces them to trust, which cybercriminals never forget to target.

In 2020, the efficient manner of social engineering attacks targeted the people through a tweet. The attacker managed to post carefully baiting tweets from high profile people offering to pay back to the community and telling people to send the amount to the account and get back the double fund within 30 minutes. The tweet’s urgent and helpful tone deceived many people, and they ended up transferring the fund to the attacker account only to find out it was a social engineering scam.

Curiosity

Social engineering attackers never miss taking advantage of the critical event by initialising the campaign to induce human curiosity and phishing attempts.

In 2019, the threat attacker began a scam campaign on the Boeing 737 Max aircraft crash with phishing emails to disclose the critical information leaked on the dark web about future plane crashes of similar nature. In the deception of protecting and restricting people to travel in those aeroplanes, the attacker distributes malware in the form of attachment, claiming to have leaked data about the plane crash.

What are the six principles of social engineering?

Social engineering attack layout base their structure on the art of persuasion. These six key principles of persuasion established by Robert Cialdini, a famous behavioural psychologist, are:

Reciprocity – By nature, humans tend to return a favour.
Commitment and Consistency – If people commit, it is highly likely they will honour that commitment. Therefore, even if you may have observed that people continue to honour the original word by removing certain motivations after commitment.
Social Proof – Just because other people around you are doing, people do similar things.
Authority – Humans tend to follow authoritative personalities
Liking – If you like someone, he/she can easily persuade you.
Scarcity – Scarcity generates demand – as simple as that.

Why is social engineering dangerous?

Social engineering has a disastrous effect, and it is dangerous as any other cyber attack because of the tactic and attack nature. The frequency of social engineering attacks targeting small, mid-size to large enterprises has been increased worldwide. The defensive security tools and software are being introduced now and then, but that does not significantly decrease the social engineering attack vector.

Social engineering is more dangerous than any other cyber attack because of its attack nature and its influence on the human mind to obtain the desired result or action. Such a high ratio of social engineering attacks is the influence that social engineers create to manipulate the minds instead of fooling the tools or using any control breaking technologies.

We have discussed the types and techniques of social engineering attacks in this article. Now we must understand how attackers craft their strategies to trick the mind and make the individual follow their direction.

Social engineers use the same social science phenomena in cyber security to influence behaviour to change how one behaves under certain circumstances. Attackers often use the reverse social engineering tactic to trap the target into their activity and use the fundamental human behaviour to exploit the weaknesses. Sometimes they do this by trapping the human into the context of curiosity, sometimes with greed or sometimes with the offers mentioned earlier, yet some great strengths can be turned into significant weaknesses and help social attackers become successful in their attempt.

Let’s understand it this way.

Simple human nature manipulation: One of the human nature that makes the individual fall for a phishing scam or social engineering scam is the habit of filtering out and skim through the information. Most of us are not interested in reading long content or information. We tend to find out only the critical data or knowledge. In doing so, we often click malicious websites or download documents that result in successful social engineering, especially phishing attempts.

Assistive human nature manipulation

Humans have a helpful nature; many are soft-hearted and always up to help others. This is something cyber criminals do on their identified subject. They use their assistive spirit of helping others and craft phishing attack or baiting attack while asking for help.

Familiar nature manipulation

Cyber criminals trick their targets by creating normal circumstances. Human nature guards down the restriction for the people they know or sometimes in some familiar matter. This benefits the attacker to make the scenarios, building relationships or friendship with the victim to later take advantage of it.

Emotional nature manipulation

Human creatures follow emotion, and in the feeling, they make the right and wrong decision or often overlook some of the things. Emotional manipulation is another psychological deception that benefits the most in crafting the social engineering scam.

Is social engineering illegal?

Social engineering is a common cyber-attack vector that has been enlisted in many cases related to cyber crime. To perform social engineering, you need to manipulate human minds with charisma and trust. Hence, as they give up sensitive information like system or finance credentials which later can be used by hackers for abusing security controls of an organisation or performing fraud through identity theft.

All these approaches are illegal because it manipulates people’s minds into doing something awful without noticing any consequences beforehand. This makes them believe anything about how much good this will bring their lives when there might not even have such potential benefits.

Cybercrime is a slippery slope and can lead to fines, prison time, and other consequences. Social engineering often leads to serious penalties for the person committing it—especially when people get attacked by phishing or spear-phishing attacks that result in a financial loss on their behalf. The suspected perpetrator typically has losses of his own monetary assets reimbursed as well if he’s caught doing such damage, so be careful not to commit internet fraud!

Social Engineering is a criminal act if it’s carried out without the consent of an organisation- but only when they have given that permission can they legally be subject to this type of test.

Social engineering toolkit

The Social-Engineer Toolkit (SET) is a free tool used to make believable attacks to trick the victim. The SET has custom attack vectors, payloads and scripts that allow you to prepare and plan for social engineering assessments in no time.

Social engineering prevention

There is no denying that technologies such as Artificial Intelligence, Machine Learning, etc., are the marvel of human mind creation. They are the best that happen to facilitate the digital sphere and security arena. Defence and monitoring tools are the excellent investment any business can make to protect its cyber environment from invasion and malicious intruders, known-unknown attacks. Still, they are nothing if the human mind cannot intercept the threat coming to it.

It is not like tools, technologies, and defence mechanisms do not block the external threats or provide a safe path to interact with the outside environment; the fact is they fail when it comes to human-to-human hacking. For a robust defensive foundation and internal threat prevention, it is necessary to be aware of the human minds with various security education, training, and awareness.

Social engineering methods have been evolved with time and technologies. However, cyber criminals’ behaviour has remained constant to trick individuals and employees with basic fraud and mind manipulation techniques. There is so one bullet to kill the switch of social engineering attacks. The only way to restrict the attacker from launching a successful social engineering scam is to understand the significance of this threat and how it can be manifested.

The covid-19 has already boosted the cyber attack, let alone in 2020, 33% of all breaches involved social engineering attacks. At the same time, it has been estimated that this ratio will increase by the end of 2021. Organisations can control this cyber risk by considering all the prevention listed below, appropriate training, and proper security controls to secure both the digital and physical landscape.

Here are the following practical and advisable ways to prevent the social engineering attack from befalling over the people, process, and technologies:

Classify the critical assets and data that are important and must be protected from exposure.
Develop policies and guidelines to handle data within and outside of the organisation.
Classify the employees, partners, vendors having access and privileges to critical data.
Implement framework and security policies for vendors, third-parties who have privilege access, leading to severe disruption or consequences in a successful social engineering scam.
Implement zero-trust architecture for every classified person to access sensitive data.
Invest in a social engineering awareness campaign for employees, partners, board members, third-party vendors to help them understand the importance of data they handle, access they have, and responsibilities to prevent insider threats, spot suspicious phishing attempts, and any social engineering attack.
Perform social engineering tests by an outside party against employees to learn their defensive capabilities.
Enhance the security culture by frequent screening on random events.
Perform risk assessment, black box penetration testing to identify security gaps within the organisation to lead for actionable recommendations to improve security across the organisation.
Collect the report to find out positive and negative areas for improving security and employees’ training.
Always double-check the URL before clicking on it.
Never download or open any attachment in the form of an image, documents from an unknown and untrusted source.
Always thoroughly read the email to find social engineering indication.
Select diverse and anti-social engineering centred technologies and tools to block the threats
Invest in security incident and event management systems or SIEM solutions to ensure strong logging and monitoring processes and controls.
Consider using host-based IDS or IPS solution to detect known attacks that might have been engaged by accessing signature or behaviours.
Set-up VPN to ensure your organisation privacy on a broad level
Install proxy servers to monitor and administer internet traffic content.
Enforce regular backup policy so if anyone falls for the social engineering scam leading to compromise/corruption of systems; organisations have other ways to protect their essential data.
Keep the system updated with anti-virus, anti-malware, anti-phishing and email services.
Ensure the confirmation policy in case of personal or financial information request with a high sense of urgency
Limit the amount of employees’ information to be shared on the social network.
Do not share credentials, financial or personal information in any unverified or untrusted communication.
Install spam filters and email security products to minimise the phishing scam coming to your emails.
Some tips include generic recommendations as part of the security awareness training. Security awareness initiatives and training program are important steps in educating your employees to be aware of cyber risks.
Do not share trade, business secret through email or call.
Keep your browsers and applications up to date.
Never use the link to get directed to your bank website; always type the URL.
Stay up to date on the ongoing social engineering and phishing attack type.
Enable multi-factor authentication so if your credential got leaked or stolen, it adds an added layer of protection and greater difficulty for attackers to attempt to access your account.
Think twice before involving in any offer or free service from any source. Cross-check it by searching and asking for a more credible resource.
Never initiate the payment based on an email request, always verify it by contacting the company or the person directly. In addition to it, do not use the contact information given in the email. Verify the contact information too.
Enforce automatic locking of devices to restrict physical intrusion.
Impose no-sharing rule on all kind of devices, hardware, USB, and drives.
Never share your password with anyone, not with the IT staff in any case.
In case of already shared credentials, reset all of your passwords and inform your bank, the organisation, to block the unknown and even authorised access till the matter is resolved.

Conclusion

Without a doubt, social engineering in any form can facilitate intruders to have authorised access or get confidential information without any technical effort or breaking digital system controls. It has been the most used and most effective cyber attack method for evaluating the computer age and becoming more versatile and sophisticated with the new smishing, vishing, quid pro quo techniques etc. It is now a significant threat to all industries and businesses-whether they are startups or large enterprises. As we’ve seen many times before on television shows (and you might agree!), these attacks don’t always require some high-tech equipment to succeed; sometimes, it only takes an email from someone pretending to be from your company asking them for their password!

If you haven’t considered your social engineering vectors yet, we’re happy to discuss them!
