In the context of information security, social engineering is the psychological manipulation of people into performing actions or divulging confidential information. A type of confidence trick for the purpose of information gathering, fraud, or system access, it differs from a traditional "con" in the sense that it is often one of the many steps in a more complex fraud scheme. [1] It has also been defined as "any act that influences a person to take an action that may or may not be in their best interests." [2]

Contents

Research done in 2020 has indicated that social engineering will be one of the most prominent challenges of the upcoming decade. Having proficiency in social engineering will be increasingly important for organizations and countries, due to the impact on geopolitics as well. Social engineering raises the question of whether our decisions will be accurately informed if our primary information is engineered and biased. [3]

Social engineering attacks have been increasing in intensity and number, cementing the need for novel detection techniques and cyber security educational programs. [4]

Techniques and terms

All social engineering techniques are based on human nature of a human humanity decision-making known as cognitive biases. [5] [6]

One example of social engineering is an individual who walks into a building and posts an official-looking announcement to the company bulletin that says the number for the help desk has changed. So, when employees call for help the individual asks them for their passwords and IDs thereby gaining the ability to access the company's private information. Another example of social engineering would be that the hacker contacts the target on a social networking site and starts a conversation with the target. Gradually the hacker gains the trust of the target and then uses that trust to get access to sensitive information like password or bank account details. [7]

Pretexting

Pretexting (adj. pretextual), also known in the UK as blagging, [8] is the act of creating and using an invented scenario (the pretext) to engage a targeted victim in a manner that increases the chance the victim will divulge information or perform actions that would be unlikely in ordinary circumstances. [9] An elaborate lie, it most often involves some prior research or setup and the use of this information for impersonation (e.g., date of birth, Social Security number, last bill amount) to establish legitimacy in the mind of the target. [10]

Water holing

Water holing is a targeted social engineering strategy that capitalizes on the trust users have in websites they regularly visit. The victim feels safe to do things they would not do in a different situation. A wary person might, for example, purposefully avoid clicking a link in an unsolicited email, but the same person would not hesitate to follow a link on a website they often visit. So, the attacker prepares a trap for the unwary prey at a favored watering hole. This strategy has been successfully used to gain access to some (supposedly) very secure systems. [11]

Baiting

Baiting is like the real-world Trojan horse that uses physical media and relies on the curiosity or greed of the victim. [12] In this attack, attackers leave malware-infected floppy disks, CD-ROMs, or USB flash drives in locations people will find them (bathrooms, elevators, sidewalks, parking lots, etc.), give them legitimate and curiosity-piquing labels, and wait for victims.

Unless computer controls block infections, insertion compromises PCs "auto-running" media. Hostile devices can also be used. [13] For instance, a "lucky winner" is sent a free digital audio player compromising any computer it is plugged to. A "road apple" (the colloquial term for horse manure, suggesting the device's undesirable nature) is any removable media with malicious software left in opportunistic or conspicuous places. It may be a CD, DVD, or USB flash drive, among other media. Curious people take it and plug it into a computer, infecting the host and any attached networks. Again, hackers may give them enticing labels, such as "Employee Salaries" or "Confidential". [14]

One study published in 2016 had researchers drop 297 USB drives around the campus of the University of Illinois. The drives contained files on them that linked to webpages owned by the researchers. The researchers were able to see how many of the drives had files on them opened, but not how many were inserted into a computer without having a file opened. Of the 297 drives that were dropped, 290 (98%) of them were picked up and 135 (45%) of them "called home". [15]

Law

In common law, pretexting is an invasion of privacy tort of appropriation. [16]

Pretexting of telephone records

In December 2006, United States Congress approved a Senate sponsored bill making the pretexting of telephone records a federal felony with fines of up to $250,000 and ten years in prison for individuals (or fines of up to $500,000 for companies). It was signed by President George W. Bush on 12 January 2007. [17]

Federal legislation

The 1999 Gramm-Leach-Bliley Act (GLBA) is a U.S. Federal law that specifically addresses pretexting of banking records as an illegal act punishable under federal statutes. When a business entity such as a private investigator, SIU insurance investigator, or an adjuster conducts any type of deception, it falls under the authority of the Federal Trade Commission (FTC). This federal agency has the obligation and authority to ensure that consumers are not subjected to any unfair or deceptive business practices. US Federal Trade Commission Act, Section 5 of the FTCA states, in part: "Whenever the Commission shall have reason to believe that any such person, partnership, or corporation has been or is using any unfair method of competition or unfair or deceptive act or practice in or affecting commerce, and if it shall appear to the Commission that a proceeding by it in respect thereof would be to the interest of the public, it shall issue and serve upon such person, partnership, or corporation a complaint stating its charges in that respect."

The statute states that when someone obtains any personal, non-public information from a financial institution or the consumer, their action is subject to the statute. It relates to the consumer's relationship with the financial institution. For example, a pretexter using false pretenses either to get a consumer's address from the consumer's bank, or to get a consumer to disclose the name of their bank, would be covered. The determining principle is that pretexting only occurs when information is obtained through false pretenses.

While the sale of cell telephone records has gained significant media attention, and telecommunications records are the focus of the two bills currently before the United States Senate, many other types of private records are being bought and sold in the public market. Alongside many advertisements for cell phone records, wireline records and the records associated with calling cards are advertised. As individuals shift to VoIP telephones, it is safe to assume that those records will be offered for sale as well. Currently, it is legal to sell telephone records, but illegal to obtain them. [18]

1st Source Information Specialists

U.S. Rep. Fred Upton (R-Kalamazoo, Michigan), chairman of the Energy and Commerce Subcommittee on Telecommunications and the Internet, expressed concern over the easy access to personal mobile phone records on the Internet during a House Energy & Commerce Committee hearing on "Phone Records For Sale:Why Aren't Phone Records Safe From Pretexting?" Illinois became the first state to sue an online records broker when Attorney General Lisa Madigan sued 1st Source Information Specialists, Inc. A spokeswoman for Madigan's office said. The Florida-based company operates several Web sites that sell mobile telephone records, according to a copy of the suit. The attorneys general of Florida and Missouri quickly followed Madigan's lead, filing suits respectively, against 1st Source Information Specialists and, in Missouri's case, one other records broker – First Data Solutions, Inc.

Several wireless providers, including T-Mobile, Verizon, and Cingular filed earlier lawsuits against records brokers, with Cingular winning an injunction against First Data Solutions and 1st Source Information Specialists. U.S. Senator Charles Schumer (D-New York) introduced legislation in February 2006 aimed at curbing the practice. The Consumer Telephone Records Protection Act of 2006 would create felony criminal penalties for stealing and selling the records of mobile phone, landline, and Voice over Internet Protocol (VoIP) subscribers.

Hewlett Packard

Patricia Dunn, former chairwoman of Hewlett Packard, reported that the HP board hired a private investigation company to delve into who was responsible for leaks within the board. Dunn acknowledged that the company used the practice of pretexting to solicit the telephone records of board members and journalists. Chairman Dunn later apologized for this act and offered to step down from the board if it was desired by board members. [19] Unlike Federal law, California law specifically forbids such pretexting. The four felony charges brought on Dunn were dismissed. [20]

Notable social engineering incidents

Equifax breach help websites

Following the 2017 Equifax data breach linked to China's People's Liberation Army [21] in which over 150 million private records were leaked (including Social Security numbers, and drivers license numbers, birthdates, etc.), warnings were sent out regarding the dangers of impending security risks. [22] In the day after the establishment of a legitimate help website (equifaxsecurity2017.com) dedicated to people potentially victimized by the breach, 194 malicious domains were reserved from small variations on the URL, capitalizing on the likelihood of people mistyping. [23] [24]

2016 United States Elections Leaks

During the 2016 United States Elections, hackers associated with Russian Military Intelligence (GRU) sent phishing emails directed to members of Hillary Clinton's campaign, disguised as a Google alert. [25] Many members, including the chairman of the campaign, John Podesta, had entered their passwords thinking it would be reset, causing their personal information, and thousands of private emails and documents to be leaked. [26] With this information, they hacked into other computers in the Democratic Congressional Campaign Committee, implanting malware in them, which caused their computer activities to be monitored and leaked. [26]

Google and Facebook phishing emails

Two tech giants—Google and Facebook—were phished out of $100 million by a Lithuanian fraudster. He impersonated a hardware supplier to falsely invoice both companies over two years. [27] Despite their technological sophistication, the companies lost the money. [28]

Sony pictures leak

On 24 November 2014, the hacker group "Guardians of Peace" [29] (probably linked to North Korea) [30] leaked confidential data from the film studio Sony Pictures Entertainment. The data included emails, executive salaries, and employees' personal and family information. The phishers pretended to be high up employees to install malware on workers' computers. [31]

Notable social engineers

Susan Headley

Susan Headley became involved in phreaking with Kevin Mitnick and Lewis de Payne in Los Angeles, but later framed them for erasing the system files at US Leasing after a falling out, leading to Mitnick's first conviction. She retired to professional poker. [32]

Mike Ridpath

Mike Ridpath is a security consultant, published author, speaker and previous member of w00w00. He is well known for developing techniques and tactics for social engineering through cold calling. He became well known for live demonstrations as well as playing recorded calls after talks where he explained his thought process on what he was doing to get passwords through the phone. [33] [34] [35] [36] [37] As a child, Ridpath was connected with Badir Brothers and was widely known within the phreaking and hacking community for his articles with popular underground ezines, such as, Phrack, B4B0 and 9x on modifying Oki 900s, blueboxing, satellite hacking and RCMAC. [38] [39]

Badir Brothers

Brothers Ramy, Muzher, and Shadde Badir—all of whom were blind from birth—managed to set up an extensive phone and computer fraud scheme in Israel in the 1990s using social engineering, voice impersonation, and Braille-display computers. [40] [41]

Christopher J. Hadnagy

Christopher J. Hadnagy is an American social engineer and information technology security consultant. He is best known as an author of 4 books on social engineering and cyber security [42] [43] [44] [45] and founder of Innocent Lives Foundation, an organization that helps tracking and identifying child trafficking by seeking the assistance of information security specialists, using data from open-source intelligence (OSINT) and collaborating with law enforcement.

<span class="mw-page-title-main">Phishing</span> Form of social engineering

Phishing is a form of social engineering and a scam where attackers deceive people into revealing sensitive information or installing malware such as viruses, worms, adware, or ransomware. Phishing attacks have become increasingly sophisticated and often transparently mirror the site being targeted, allowing the attacker to observe everything while the victim navigates the site, and transverses any additional security boundaries with the victim. As of 2020, it is the most common type of cybercrime, with the FBI's Internet Crime Complaint Center reporting more incidents of phishing than any other type of cybercrime.

In addition to credit and demographic data and services to business, Equifax sells credit monitoring and fraud prevention services directly to consumers.

A black hat is a computer hacker who violates laws or ethical standards for nefarious purposes, such as cybercrime, cyberwarfare, or malice. These acts can range from piracy to identity theft. A Black hat is often referred to as a "cracker".

A security hacker or security researcher is someone who explores methods for breaching defenses and exploiting weaknesses in a computer system or network. Hackers may be motivated by a multitude of reasons, such as profit, protest, information gathering, challenge, recreation, or evaluation of a system weaknesses to assist in formulating defenses against potential hackers.

Pretexting is a type of social engineering attack that involves a situation, or pretext, created by an attacker in order to lure a victim into a vulnerable situation and to trick them into giving private information, specifically information that the victim would typically not give outside the context of the pretext. In its history, pretexting has been described as the first stage of social engineering, and has been used by the FBI to aid in investigations. A specific example of pretexting is reverse social engineering, in which the attacker tricks the victim into contacting the attacker first.

Cyber crime, or computer crime, refers to any crime that involves a computer and a network. The computer may have been used in the commission of a crime, or it may be the target. Netcrime refers, more precisely, to criminal exploitation of the Internet. Issues surrounding this type of crime have become high-profile, particularly those surrounding hacking, copyright infringement, identity theft, child pornography, and child grooming. There are also problems of privacy when confidential information is lost or intercepted, lawfully or otherwise.

There is no commonly agreed single definition of “cybercrime”. It refers to illegal internet-mediated activities that often take place in global electronic networks. Cybercrime is "international" or "transnational" – there are ‘no cyber-borders between countries'. International cybercrimes often challenge the effectiveness of domestic and international law, and law enforcement. Because existing laws in many countries are not tailored to deal with cybercrime, criminals increasingly conduct crimes on the Internet in order to take advantages of the less severe punishments or difficulties of being traced.

Social hacking describes the act of attempting to manipulate outcomes of social behaviour through orchestrated actions. The general function of social hacking is to gain access to restricted information or to a physical space without proper permission. Most often, social hacking attacks are achieved by impersonating an individual or group who is directly or indirectly known to the victims or by representing an individual or group in a position of authority. This is done through pre-meditated research and planning to gain victims’ confidence. Social hackers take great measures to present overtones of familiarity and trustworthiness to elicit confidential or personal information. Social hacking is most commonly associated as a component of “social engineering”.

Between May and July 2017, American credit bureau Equifax was breached. Private records of 147.9 million Americans along with 15.2 million British citizens and about 19,000 Canadian citizens were compromised in the breach, making it one of the largest cybercrimes related to identity theft. Equifax discovered the breach end of July, but did not disclose it to the public until September 2017. In a settlement with the United States Federal Trade Commission, Equifax offered affected users settlement funds and free credit monitoring.

Internet security awareness or Cyber security awareness refers to how much end-users know about the cyber security threats their networks face, the risks they introduce and mitigating security best practices to guide their behavior. End users are considered the weakest link and the primary vulnerability within a network. Since end-users are a major vulnerability, technical means to improve security are not enough. Organizations could also seek to reduce the risk of the human element. This could be accomplished by providing security best practice guidance for end users' awareness of cyber security. Employees could be taught about common threats and how to avoid or mitigate them.
