The Twitter account is back under Netflix's control, but the incident reminded me that people routinely have their own Netflix accounts hacked, and many don't know.
Just a few weeks ago, a colleague of mine noticed some suspicious viewing activity of the TV show "Arrow" on her Netflix, and figured out her account had been compromised.
Netflix lets multiple people use an account at the same time, and this feature is great when it allows you to mooch off a friend's account without inconveniencing them.
But one problem with this policy is that it has inadvertently created a black market for "access" to stolen Netflix accounts.
A report by McAfee Labs last year revealed you can buy access to Netflix accounts in "Dark Web" marketplaces, which can only be accessed using a special internet browser called TOR that hides your computer's digital footprint, known as an IP address.
Hackers in these marketplaces are selling lifetime access to Netflix accounts for as little as $0.50. While some of these accounts are likely purchased with stolen credit card information, others used hacked login information, Raj Samani, the CTO of Intel Security, told Tech Insider. And sometimes hackers don't even sell the stolen accounts, but rather, just dump the login credentials on the internet for people to use.
Luckily, there's an easy ways to check if you've been hacked, and fix it.
