It’s that time again—your regular Password Health Check-up is due.
Now, before your eyes start to ‘roll and scroll’, skipping on to something you haven’t heard before, listen to this–
Last week’s massive cyberattack, which outsmarted some of the best and brightest and shut down major sites like Amazon, Netflix, and Twitter for hours, equaling losses in the millions?
One of the culprits behind it all–weak passwords.
If you haven’t had time yet to read about the attack and how it all went down (literally), here’s a helpful analogy for the non-geek, via tech blogger QuHarrison Terry–
‘Imagine Dyn [the DNS provider that was attacked] is the US Postal Service. If someone wanted to shut down USPS, they would get thousands of people to stand outside of every post office, each holding thousands of pieces of mail. They would continue this for days upon days until mail begins collecting in piles ten-feet tall all over the post office. Eventually, the workers get too stressed from overwork and just quit and the USPS mail system would cease existence.’
In this case, the thousands of people at the post office were millions of ‘smart devices’ like DVRs and cameras (part of the world’s massive and growing ‘Internet of Things’ (IoT), these are physical items that are ‘internetworked’ across the information society we all know and use every day).
So how were hackers able to use (actually, ‘enslave’) these gadgets and gizmos, some of which you may have in your home or office, to bring Dyn to its knees with thousands of 10-feet tall piles of requests (to go back to our analogy outside the post office)?
Simple. The devices were easy to hack and infect with malware because they were set with weak passwords.
Many of the products used were made in China by Hangzhou Xiongmai Technology, which said on Sunday that their products have weak default passwords that are easy to infect. As of Sunday, Mirai (the malware used in the attack) had been found spreading to at least 500,000 devices.
Okay so, once again, here’s Password Safety 101. First off, as astronomer Clifford Stoll has taught us,
