Hackers profit off our collective misery

A hacking collective calling itself ShinyHunters is selling a staggering amount of stolen accounts on Dark Web marketplaces for less than one cent per account. According to ZDNet, more than 73 million accounts are involved in the breach, which stretches across 10 different platforms, and the going rate is approximately $18,000 for all of them. Individual databases are being sold separately, which means any cybercriminal with enough Bitcoin could easily gain access to millions of accounts for a relatively small amount of money. These accounts also contain a number of data points that could potentially identify users, such as email addresses, phone numbers, payment information and more. If you use any of the following 10 platforms, you’ll need to change your passwords as soon as possible. And keep in mind, since the databases can be copied, multiple cybercriminals can buy it. Your data could easily end up in more hands than one if you give it enough time.
