I just got some notifications on the 20th December that someone in Wollongong had signed into my gmail accounts. I breifly lived in Wollongong in late 2013 for 3 months, and I had a falling out with my flatmates, thats why I left. I suspect it must be them, they are obviously very vindictive that they are trying to crack my password and presumably take my personal information. The password was 8 characters long with a capital and a number in it. How hard is it to crack a password like that? Is there some dark net software people can buy that will do it? I have changed all my passwords to new ones unrelated to the old ones. I am just worried they might do it again. Is this a valid fear?
