Is Someone Watching You Through Your Webcam? A study on the awareness and concern of webcam hacking No longer limited to Hollywood movies about cybercrime, web camera hacking has stealthily – and aggressively – broken into average American households. Similar to the legendary Trojan horse used by Greek soldiers to enter Troy, the glamour of today’s laptops often lulls consumers into a false sense of security. Unaware of the risks, computer users often drop their guard – allowing hackers to enter their homes undetected. An estimated 170 million people use laptop computers worldwide (eTForecasts, 2010). The vast majority of these machines have built-in webcam technology (Boatman, 2007) that allows users to experience and record real-time interaction. While web camera technology is popular with social media and Skype users, many consumers have no idea that webcam hacking is both widespread and simple (Kumar, 2009). Inputting the phrase “how to hack a webcam” into any search engine easily accesses a variety of instructional websites, videos, and how-to-guides that empower hackers with the ability to secretly enter people’s homes. PROBLEM Naïve about privacy risks, unsuspecting laptop users are easy prey for webcam hackers. Consider some recent cases: • A Rutgers’ student committed suicide after his roommate used a webcam to record the student kissing another man (Mulvihill, 2012; Pitts, 2010). • A Philadelphia school district settled a lawsuit for $610,000 after students learned the district could spy on them by remotely activating web cameras in school-issued laptops (Mah, 2011a, 2011b; Martin, 2010). • A Wyoming couple discovered a rental company that sold them a laptop used the machine’s web camera to take pictures for use in the company’s bill collection process (Jamieson & Robinson, 2011; Shamlian, 2012). Unfortunately, such incidents are not isolated. In 2010, one “cyber-peeper” was jailed for 18 months after being found guilty of hacking into and turning on thousands of web cameras belonging to individuals and businesses. According to prosecutors, the hacker distributed “cleverly-disguised e-mails, measured by the millions, if not tens of millions, bearing sophisticated viruses” (Wonzy, 2010, para. 8). Parham Eftekhari, President and Founder of CamPatch, a company that manufactures webcam covers, explained that a skilled webcam hacker can access someone’s laptop in a minute or less. After gaining control of a machine’s web camera, cybercriminals have the ability to “remotely access, intercept and monitor customers’ private, personal electronic communications, information, screen shots, keystrokes or images captured on webcams” (Jamieson & Robinson, 2011, p. 1). “While web camera technology is popular with social media and Skype users, many consumers have no idea that webcam hacking is both widespread and simple (Kumar, 2009).” Eftekhari, who has over 10 years of experience in IT and telecommunications, explained that three particular laptop behaviors increase the risk of webcam hacking: 1 Is Someone Watching You Through Your Webcam? • Frequency of use – The risk of hacking is higher when a laptop is on. Turning the machine off after use significantly reduces the risk a web camera will be ‘hijacked.’ • Lack of virus protection – Since most hackers use a virus or Trojan to gain access to a webcam (Boatman, 2007; F-Secure, 2010), the absence of reliable virus protection increases the risk of web camera hacking. While installing and maintaining strong virus protection software substantially decreases the risk of hacking, laptop users should remember that such approaches do not eliminate all risks. • Failure to close the laptop – When a laptop is left open, hackers can easily observe and record activities occurring around the machine. Shutting a laptop physically prevents hackers from cyber-peeping even if the webcam has been hacked. PURPOSE This study investigated consumers’ attitudes about web camera hacking. In particular, the study: • Measured to what extent laptop users are aware that webcams can be hacked • Determined to what extent people are at risk of web camera hacking • Explored how laptop users would feel if their web camera was ‘hijacked’ METHODOLOGY Laptop users were invited to participate in an online survey about web cameras. Invitations were distributed via social media (Facebook and LinkedIn) and participants were encouraged to share a URL to the survey with other laptop users. RESULTS Sample After two weeks of data collection in March 2012, 250 laptop users responded to the survey. Equal percentages of men and women participated. The average age was 43.6 with a standard deviation of 13.9. About 37% (n = 93) of the sample was represented by members of Generation X (born between 1965 and 1981), 36% (n = 89) were Baby Boomers (1946-1964), 21% (n = 53) represented Generation Y (1982 to 1993), and only one person was from Generation Z. About 3 out of 4 participants said they did not have children under 18 living in their households. Participants’ occupations varied. About 2 out of 3 survey takers reported working for private businesses, with 23% employed with educational institutions. Approximately 10% said they work for the government; and 2% represented other occupations. Assuming a population of 170 million laptop users (eTForecasts, 2010), a sample size of 250, and a 95% confidence level, there was a 6.2 margin of error. 51% Aware 49% Unaware Figure 1. Study participants’ awareness of web camera hacking. Webcam Hacking Awareness As shown in Figure 1, 51% of survey participants (n = 117) reported being unaware that it is possible for an unauthorized person to activate a laptop’s web camera to observe and record a person’s activities. 2 Is Someone Watching You Through Your Webcam? Awareness by Gender Women were significantly more unaware of webcam hacking than men. Approximately 61% of women (n = 72), compared to 40% of men (n = 45), did not know about the risk of web camera hacking (see Figure 2). Male Aware 60% Female Unaware 40% Unaware 61% Aware 39% Figure 2. Comparison of men and women’s awareness of web camera hacking. Awareness by Generation Generation Y laptop users were the least informed about the risk – with almost 6 of 10 saying they were not aware of webcam hacking. Baby Boomers were similarly unaware, with 55% indicating they had no prior knowledge of such activities. In contrast, less than half (45%) of Generation X participants reported being unaware of webcam hacking risks (see Figure 3). Generation X (n=83) Aware 45% Unaware 55% Baby Boomers (n=84) Unaware 45% Aware 55% Generation Y (n=51) Aware 43% Figure 3. Awareness of web camera hacking by generation. 3 Unaware 57% Is Someone Watching You Through Your Webcam? Awareness by Occupation About 6 in 10 study participants who worked in the field of education (n = 52) were unaware of webcam hacking (see Figure 4). Nearly half (n = 52, 52%) of individuals who worked in non-government occupations were similarly unaware. In contrast, only about 3 in 10 government workers and 2 in 10 employees from other occupations were unaware of webcam hacking. 70% 60% 60% 52% 50% Percentage 40% 29% 30% 17% 20% 10% 0% Education Non-Government Government Other Unawareness of Webcam Hacking Figure 4. Percentage of unawareness of web camera hacking by occupation. Awareness by Frequency of Laptop Use As shown in Figure 5, regardless of the frequency of their laptop use, study participants tended to be equally unaware of web camera hacking risks. Daily laptop users had the lowest level of unawareness, with about half (49%) indicating they were unaware. Low (51%) and medium frequency (57%) laptop users were similarly unaware. 70% 57% 60% 51% 49% 50% Percentage 40% 30% 20% 10% 0% Low (n=86) Medium (n=21) High (n=124) Unawareness of Webcam Hacking Figure 5. Percentage of participant unawareness of webcam hacking by frequency of laptop use. 4 Is Someone Watching You Through Your Webcam? Webcam Hacking Risk An overall webcam risk score was computed for laptop users based on their participation in three high-risk laptop behaviors: • Frequency of use (1 = low, 2 = medium, 3 = high) • Lack of virus protection (1 = virus protection, 2 = no virus protection) • Failure to close the laptop (1 = close every time, 2 = close when done for the day, 3 = always leave open) Risk scores ranged from 3 (little to no risk) to 8 (high risk). The entire sample had an average webcam hacking risk score of 5.25 with a standard deviation of 1.31. Regardless of laptop users’ gender, generation, occupation, awareness, or concern, all laptop users in the study had statistically similar risks of webcam hacking. However, other comparative trends emerged. As indicated in Figures 6 and 7, survey participants who were aware of webcam hacking reported participating in behaviors that placed them at slightly higher risk. Likewise, laptop users who reported higher levels of concern were at more risk than individuals expressing less concern. Men, Generation X, and participants working in the field of education most frequently took part in behaviors that placed them at risk of webcam hacking.

Webcam Hacking Reactions Before sharing their reactions to webcam hacking, study participants listed locations where they use laptops. As shown in Figure 8, the most frequently mentioned places were the living room (n = 154, 62%) or home office (n = 145, 58%). Other locations included the bedroom (n = 110, 44%), public places (i.e., airports, internet cafes; n = 98, 39%), work office (n = 87, 35%), kitchen (n = 83, 33%), outdoors (n = 49, 20%), car (n = 27, 11%), bathroom (n = 19, 8%), and/or garage (n = 3, 1%).

Laptop User Concern About 8 out of 10 laptop users expressed concern about the risk of webcam hacking (see Figure 9). No Concern 18% Concern 82% Concern 82% Figure 9. Study participants’ concern about web camera hacking. Concern was higher for individuals who were unaware of webcam hacking. As shown in Figure 10, 79% of people who knew about web camera hacking before the survey expressed concern. In contrast, 84% of individuals who were informed about the risk during the survey shared similar concerns. UNAWARE AWARE No Concern 16% No Concern 21% Concern 79% Concern 84% Figure 10. Comparison of study participants’ concern by awareness of web camera hacking. 8 Is Someone Watching You Through Your Webcam? Women (86%) expressed significantly more concern than men (77%); and older laptop users were more concerned than younger users. Approximately 82% of participants from the Silent generation (n = 11) indicated they were concerned; while 87% of Baby Boomer (n = 84), 83% of Generation X (n = 81) and 72% of Generation Y (n = 50) participants expressing similar concerns. Laptop User Feelings Study participants also described, in their own words, how they would feel if their web camera was hijacked. The study’s 250 laptop users shared 299 open-ended comments. As shown in the text cloud in Figure 11, most of these comments (92%) expressed negative emotions. Many laptop users said they would feel violated, helpless, embarrassed, scared, “creeped out,” and/or “mad as hell!” In contrast, 3% of remarks expressed positive feelings about webcam hacking. Most of the study participants who shared favorable comments said they would feel entertained or flattered if someone hacked their web camera. One participant joked, “I would feel like dancing . . . naked!” Another remarked, “I would laugh because [watching me] would be a snoozefest!” Interestingly, all but one of the favorable remarks were expressed by men. Other comments were either neutral in nature (“Not surprised” or “I wouldn’t care”) or included remarks unrelated to feelings about webcam hacking. Figure 11. Text cloud of laptop users’ feelings about webcam hacking. 9 Is Someone Watching You Through Your Webcam? DISCUSSION The rapid growth of laptop computers with built-in web cameras substantially increases the risk of webcam hacking, privacy invasion, and other types of cybercrime (e.g., bullying, hate crimes, stalking, etc.). Several high-profile media reports about recent webcam hacking have focused attention on the increase in cyber-related privacy invasion. Analysis of demographic, situational, and behavioral trends suggests multiple approaches may be necessary to deal with the problem of webcam hijacking. Demographic Analysis Although every demographic group examined in the study displayed statistically similar risks of webcam hacking, men and Gen Xers (ages 31 to 47) reported slightly more risky laptop behaviors (see Figure 6). This trend emerged despite the fact that both men and Gen Xers were more aware of web camera hacking than women, Baby Boomers, or members of Generation Y (see Figures 2 and 3). Interestingly, male laptop users were significantly more likely than women to describe favorable feelings about webcam hacking – suggesting online privacy may be less important to men. When compared to government and business workers, individuals employed in education displayed slightly riskier laptop behavior (see Figure 6). However, unlike men and Gen Xers who tended to be aware of webcam hijacking, 6 out of 10 Webcams provide creative hackers laptop users who work in academia said they were unaware of web camera hacking (see Figure 6). This trend with limitless access to potentially is unfortunate since teachers who are unaware of webcam embarrassing information that could be risks may inadvertently model risky behaviors to high school and college students (two large groups of laptop users). If, on used to bully or blackmail laptop owners. the other hand, teachers were more aware of privacy issues Beyond peeping, the technology also surrounding the use of web cameras, educators could help socialize a large number of laptop users about ways to reduce provides opportunities for cyber-stalking, web camera hacking. hate crimes, and identity theft. Situational Analysis When laptops were first introduced, they typically required a wired internet connection and had limited functionality (e.g., word processing, email, website browsing). Tethered to an Ethernet cable, such machines tended to be used primarily in home or business offices. In contrast, today’s laptops use wireless connections and offer robust functionality (e.g., social media, music, video, Skype, etc.). Not surprisingly, laptops have migrated to a variety of private locations, such as living rooms, bedrooms, kitchens, and bathrooms (see Figure 7). They also accompany people to internet cafes, restaurants, airports, parking lots, and pools. While such portability provides people with tremendous convenience, laptops present webcam hackers with a smorgasbord of privacy invasion opportunities. As shown in Figure 7, 62% of laptop owners in the study indicated they use their machines in the living room – where a webcam hacker could watch and/or record a family’s children, private conversations, television programs, and/or reading material. About 4 in 10 laptop users work in a bedroom, where cyber-peepers might observe people in their underwear and/or eavesdrop on private activities. Privy to a variety of compromising situations, webcam hackers have numerous opportunities for cybercrime. As indicated earlier, after a web camera secretly recorded a gay Rutgers’s student kissing another man, deeply embarrassed, the student committed suicide (Mulvihill, 2012; Pitts, 2010). Webcams provide creative hackers with limitless access to potentially embarrassing information that could be used to bully or blackmail laptop owners. Beyond peeping, the technology also provides opportunities for cyber-stalking, hate crimes, and identity theft. 10 Is Someone Watching You Through Your Webcam? Behavioral Analysis Despite media coverage of the issue (Mah, 2011a, 2011b; Martin, 2010; Mulvihill, 2012; Pitts, 2010; Shamlian, 2012), many laptop owners do nothing to protect themselves from webcam hackers. Many fail to act because they did not know such activities were possible. Half the laptop users surveyed in this study were unaware of the risks of webcam hacking. With approximately 170 million people using laptops worldwide (eTForecasts, 2010), the study’s findings suggest there could be as many as 50 million unsuspecting laptop users who could be victimized by webcam hackers. Upon learning their webcams could be hacked, several study participants said they planned to cover their webcams immediately. Such responses suggest educational campaigns about the risk of webcam hacking could prompt laptop users to take action to protect their privacy. In contrast, other laptop users in the study were not concerned – even though they were aware of web camera hacking. A few survey participants, primarily men, joked about boring (or entertaining) cyber-peepers. Such comments suggested some laptop users do not believe webcam hackers pose a significant threat. Such a lassie faire attitude may be due, in part, to the availability of virus protection software; 76% of study participants said their machines were protected by software, such as Norton, McAfee, or Webroot. Since hackers typically use a virus or Trojan to gain access to a web camera, laptop users may believe virus protection software makes them impervious to hacking. It is important to remember, however, that such software is designed to prevent known threats. New viruses and Trojans are frequently introduced into cyberspace (SecurePC, 2012; “Virus or Trojan Protection Tips,” 2012), with some estimates as high as 200 . . . the use of virus protection makes new types per month (Kuo, 1999). An internet security report from 2006 cited by the Department of Homeland Security the hacker’s job more difficult – but not showed documentation for more than 2,200 new computer impossible. Laptop users who believe vulnerabilities and almost 7,000 new worms and viruses in the first six months of 2006 – setting a record for the most virus protection is a ‘bulletproof’ way to ever recorded in a 6-month period (Department of Homestop cybercriminals might be lulled into land Security, 2008). As a result, the use of virus protection makes the hacker’s job more difficult – but not impossible. a false sense of security - leaving them Laptop users who believe virus protection is a ‘bulletproof’ vulnerable to emergent threats. way to stop cybercriminals might be lulled into a false sense of security - leaving them vulnerable to emergent threats. RECOMMENDATIONS Get Covered – While virus protection software is very helpful, a cyber-security expert in the Pentagon noted that the only definitive way to prevent such hacking is to cover the lens of your webcam (P. Eftekhari, personal communication, March 20, 2012). Such an approach is highly effective since it physically stops hackers from watching and recording any laptop activities. Keep Informed – Given the rapid growth of webcam technology (e.g., laptops, tablets, game consoles, cell phones, and televisions), it is imperative for consumers as well as organizations to understand how web camera technology may encroach upon privacy. The CamPatch Academy (2012), founded by Eftekhari, provides free resources for web camera users who are interested in learning more about webcam hacking. “In the past, it’s been difficult to find information about the risks of webcam hacking,” Eftekhari said. “The CamPatch Academy provides a central repository of factual information about web camera risks as well as tools and techniques about how to protect yourself.” Stay Alert – Laptops typically have a light that indicates the camera is active. If a webcam light unexpectedly activates, be aware that it may be broadcasting an image. Also be vigilant about maintaining virus protection software. Most hackers cannot gain access to a computer without first infecting a machine’s software with a virus or Trojan. Finally, when using laptops that belong to other organizations, as was the case with the couple in Wyoming (Jamieson & Robinson, 2011; Shamlian, 2012) and the school district in Philadelphia (Mah, 2011a, 2011b; Martin, 2010), make sure you read and understand your rights and responsibilities. Close your Laptop – When you’re not using your laptop, simply close it or point it toward the wall. Doing this will ensure that even if someone does hack into your webcam they won’t see anything. CONCLUSION 11 Is Someone Watching You Through Your Webcam? CONCLUSION In several respects, webcam hacking is similar to identity theft – it is a crime. When the phenomena first emerged, most Americans were unaware someone could use a Social Security number to secretly open credit card accounts and/or take out unauthorized loans. The public at large only became aware after thousands of victims had their lives and credit ruined. With webcam technology expanding, privacy invasion risks will continue to grow. Opportunities for abuse are limited only by the creativity and imagination of cyber-criminals. Given the significant risk, today’s laptop owners need to be aware that hackers are capable of secretly entering their homes through the lens of a web camera. As awareness and concern about the issue grows, laptop users face a simple choice: • Do nothing – leaving their machines defenseless against webcam hackers or • Act now – protecting their privacy by proactively blocking potential hackers 12 Is Someone Watching You Through Your Webcam?
