Sites as duduckgo.com say they are not tracking their users. How mere mortals, not conversant on the innards of the Web (my case), could confirm that?
They dont track as such but do collect data, mostly just country and search term. nothing like google
b) Virtual keyboards offered for home banking, couldn't be reverse engineered for an on-the-fly decoding?
Hard or soft keyboard makes no difference
Sites offering to verify how good/strong your passwords are, aren't they plain collecting points of passwords from candid users?
Yes these end up in tools for rainbow cracking passwords, they are not looking to match user to password, they are looking for the most common/most used so tools can be adjusted when password cracking.
Worst thing is fixed lengh passwords, those that make you do say 6 letter one. Straight away a hacker knows to set the tool to try only 6 letter combinations. You would believe how simply most passwords are, make people add a number and 99% choose number? yes 1 ask then to choose 2 numbers and most use? yes 11.
Best password?
One thats unpredictable, it used to be add a special character at the start then a number then the word then at the end a special character then a number. These are now all solid in rainbow tables and take mostly just over 75 mins to crack a hard one using GPU rainbow cracking.
So pick a phrase.........
Lets say its for ETO and you want a length of nine
Pick 2 numbers mid range but not too close or whatever number you want
56
Then the phrase
electronics is my hobby online
Take the phrase and do one of two things
1)EiMhO
2)oHmIe
so now we have 56EiMhO
now two special charaters
not the = sign please!
or !
%£
final password
56EiMhO%£
Try it and see how long to crack, fast machine dual graphics card using Kali linux and rainbow tables and i am already upto 2 hours most hacking machines that would equal around 10 hours work so far and the tables havnt got close yet.
Or you can switch it around a bit, but thats the general idea to make a password you can remember and is hard to crack.
