For a couple of years, people have been receiving extortion emails in which the intended victim is told that his computer and web cam have been hacked and that the scammers have video of him watching porn online. They threaten to send the videos to people on his contact list unless he pays a ransom in Bitcoin or some other cryptocurrency. The truth is that while it is possible to hack into someone’s webcam, these letters are being sent out as mass mailings without the videos they claim to have. The scammers’ hope is that some people will be fearful enough to send the ransom. In the Scam of the day for January 27, 2019 I wrote about how the scam had evolved whereby, in order to appear as a more legitimate threat, the scammer included in the email a password the targeted victim had used. Again, however, this email extortion threat is baseless. The password that was included in some versions of this email scam is indeed one that the targeted extortion victim had used, however, it was obtained by the scammer from one of the many data breaches in which passwords were stolen. This emphasizes the need to have unique passwords for all of your online accounts so that if there is a data breach in which your password is compromised, it will not pose a threat to all of your online accounts.
This scam also illustrates the vulnerabilities of webcams to being hacked. There have been a number of scams of which I have reported in which people’s webcams have been hacked and compromising videos taken. Often when people install webcams, they use default logins and passwords. These default passwords are easy to find online. Generally, when you hook up anything wireless to your router, it comes with a password and login so it is critical that whenever you install any of these Internet of Things devices, you change the password and login to protect yourself, which leads us to my second concern – routers. A study by security company Avast found that about 80% of Americans do not properly secure their routers, leaving themselves vulnerable to being hacked. Many people still use either default passwords or easily guessed passwords, such as “password” for their routers.
In the latest evolution of the sextortion scam, the scammers are using subject lines that appear to be a security alert. Often the subject line will include the targeted victim’s email address or password to get their attention. Some of the subject line content, as discovered by Barracuda Research include:
email@example.com wa under attack change your password
Your account has been hacked you need to unlock
Change your password (password) immediately your account has been hacked
Hackers know your password (password) password must be changed now
As we connect to the Internet through more and more devices that are a part of the Internet of Things, it becomes increasingly important to be cognizant of maintaining proper security in all devices including, of course, routers and webcams. Laziness can have dire consequences. Never use default logins and passwords. As soon as you install any device that accesses the Internet, make sure that you protect yourself with secure logins and passwords.
It is not difficult to hack into the webcam of a computer from afar. The same types of tricks used to get people to unwittingly download keystroke logging malware that enables the hacker to gather all of the personal information from your computer to be used to make you a victim of identity theft can be used to get you to download the malware that enables the hacker to take control of your webcam. Never click on links in emails or download attachments unless you are absolutely positive they are legitimate. They may be riddled with malware. Also, install and maintain anti-malware and anti-virus software on your computer and other electronic devices. For external webcams that are not a built-in component of your computer, a red light will signal that the camera is operating. Be aware of this. It is a good idea to merely disconnect the external webcam when you are not using it or merely take a post-it and cover the webcam’s lens whenever you are not using it. Last year a photograph taken in 2015 was made public showing Pope Francis using his iPad with a sticker over the built in web camera. This simple technique is also used by Mark Zuckerberg, former FBI Director James Comey and me. It is a simple and easy solution. For built in webcams, they too will generally have a blue light to indicate that it is operating, however, again, it is a good idea to merely cover the lens when you are not using it.
