It’s often noted that humans are the weakest link when it comes to
cybersecurity. To exploit that vulnerability, many hackers engage in
social engineering to support their cyberattack efforts and obtain
valuable information. Social engineers target humans, rather than
technology, to gather useful intel.
Social
engineering brings the con into the digital age. Instead of using
personal interactions to build rapport and charm users into certain
actions, social engineering leverages a lack of awareness around digital
tools and the willingness to share on digital platforms. The end result
is the same: psychological manipulation that leads to handing over
sensitive info.
Social Engineering Defined
The term social engineering refers
to methods employed by hackers to gain the trust of an end user so that
the hacker can obtain information that can be used to access data or
systems. Social engineering typically involves impersonating
representatives of legitimate organizations to manipulate people into
supplying information such as passwords or personal details.
Social
engineering can involve phone calls, emails or texts. Sometimes
referred to as “human hackers,” social engineers employ a variety of
methods to convince users to divulge information, often masquerading as
tech support or bank employees.
How Does Social Engineering Work?
Hackers develop different
tactics to support their social engineering pursuits. Most social
engineering attacks follow this path:
- Research the target.
The purpose of social engineering is to convince a user that you
represent a trusted institution. Social engineers will often attempt to
develop a rapport by offering easily obtainable details, such as
birthdate or phone number, as evidence of their legitimacy. Much of this
information is publicly available, and social engineers typically scout
social media to gather this type of vulnerable data.
- Make contact with the target.
The attacker makes contact directly with the target. Social engineers
use the information they’ve gathered to validate their fake identity.
The target is then asked to provide sensitive information the hacker can
exploit.
- Attack. Using the details they have
covertly obtained, social engineers launch their attack. This could
involve accessing systems using acquired passwords, performing a classic
case of stolen identity or putting the information to use for personal
or political gain.
History of Social Engineering
Social engineering is a
practice that is as old as time. As long as there has been coveted
information, there have been people seeking to exploit it.
The
term social engineering was first used by Dutch industrialist J.C. Van
Marken in 1894. Van Marken suggested that specialists were needed to
attend to human challenges in addition to technical ones. In 1911,
Edward L. Earp wrote Social Engineer as a way to encourage people to
handle social relations similarly to how they approach machineries.
In
modern times, social engineering has come to reference the practice of
deceiving people to obtain valuable information, which is often followed
up by a cyberattack.
Here are some of the most famous cybersecurity social engineering examples.
Target Data Breach
In
2013, more than 110 million customers fell victim to a social
engineering attack on Target. Social engineering techniques were used on
an HVAC company that had remote access to Target’s network. The HVAC
company was then compromised with malware,
which in turn infected Target’s systems. The attack resulted in the
loss of emails, names, addresses, phone numbers and credit and debit
card information.
Yahoo Security Breaches
In 2013 and 2014, two attacks compromised Yahoo email-user information. The second attack was accomplished via a spear-phishing
campaign targeted to a Yahoo engineer. The individual took the bait,
giving hackers access to names, email addresses, phone numbers, dates of
birth and passwords. This attack also gave hackers the ability to
access user accounts without passwords.
CIA Attack
A
15-year-old was able to take control of the secure emails of John
Brennan, the director of the CIA. Kane Gamble used social engineering to
convince Verizon to provide personal details about Brennan, which he
later used to impersonate the CIA director. Gamble was able to access
Brennan’s email by changing security questions and passwords with
gathered intel, allowing the 15-year-old to view sensitive military
information.
Types of Social Engineering
Social engineering is a general
term that refers to a broad range of manipulation tactics used by
hackers to acquire information.
- Baiting:
Baiting is a social engineering attack where the attacker entices the
user with a free item to lure them into clicking on a link. This may
come in the form of a free music or movie download lined up with the
user’s interests. When the unsuspecting user clicks the link, they
become infected with malware.
- Phishing:
Phishing is a type of social engineering attack that uses email, phone
or text to entice a user to click on a malicious link. The communication
appears to be from a legitimate source connected to the user. When the
user selects the ill-intentioned link, the user’s device or system
becomes infected with malware and data is often compromised.
- Pretexting:
This tactic is one more commonly associated with the term social
engineering. With pretexting, an individual impersonates a
representative from a trusted organization with the goal of acquiring
sensitive information. This social engineering technique relies heavily
on gathering research before initiating contact with the target.
- Quid Pro Quo:
The quid pro quo attack is a variation of baiting. Often known as the
“something for something” social engineering technique, the quid pro quo
attack involves promising a service or benefit for complying with the
request of an attacker. For example, a social engineer may promise a
free software upgrade to entice a user to download what is actually
malware to their system.
- Reverse Social Engineering:
In this kind of social engineering scheme, the attacker convinces a
target that they have a problem or issue and then positions themselves
with a solution. The target then initiates contact with the social
engineer believing that they are able to solve their problem.
- Tailgating:
This social engineering tactic is a physical attack. With tailgating, a
hacker gains access to restricted areas of a building by following an
approved employee into the building and piggybacking on their
credentials. In these cases, the social engineer often pretends to be an
employee or even a delivery person.
- Whaling and Spear Phishing:
These attacks are a variation of phishing and, because they target a
specific individual, they require a significant amount of research. In
whaling attacks, these individuals are high-profile people, often
executives or the C-suite.
How to Prevent and Protect Against Social Engineering
The
best form of prevention against social engineering attacks is end-user
training. Teaching your employees how to recognize social engineering
tactics and avoid them is of the utmost importance.
Here are some points to help support your training efforts.
- Research any suspicious calls, emails or texts.
- Open attachments only from trusted sources.
- Immediately
delete any emails or texts asking for passwords or personally
identifiable information (PII), such as social security numbers or
financial information.
- Don’t open any emails promising prizes or notification of winnings.
- Download software only from approved sources.
- Be wary of urgent requests or solicitations for help.
- Make sure you have spam filters and antivirus software on your device.
- When in doubt, contact IT to confirm any technology-related requests.
What’s the Difference Between Ransomware vs. Malware vs. Social Engineering vs. Phishing?
Ransomware, malware, social engineering and phishing all encompass different forms of ill-intentioned cyberattacks.
- Malware is a general term formed by the words “malicious” and “software” that
describes different types of software intended to compromise
systems, obtain sensitive data or gain unsanctioned access to a network.
- Ransomware is a category of malware where attackers use various methods to encrypt
your data, making
it inaccessible, or bar you from entry to a particular system or
device. Attackers then demand a ransom in exchange for reinstating your
access.
- Social Engineering, by contrast, is a
method used to extract sensitive details by way of human manipulation.
With social engineering, hackers connect with users while pretending to
represent a legitimate organization and seek to ascertain
critical information such as account numbers or passwords.
- Phishing is a form of social engineering that involves email, phone, text or illegitimate websites.
In both instances, the collected information is used to access protected accounts or data.
While
our guide acts as an introduction into the threats posed by social
engineering, this is by no means an exhaustive list. Social engineering
and the cybersecurity world change on a daily basis, and attacks are
becoming increasingly sophisticated. The best way to combat cyberattacks
is to stay informed about the latest attacks.
