Weirdly, in Firefox 7zip.com is blocked but www.7zip.com isn't.
If you type '7zip' in the address bar and then press Ctrl+Enter to go to the address, you'll get owned, because that key-combo adds the www at the beginning.
Yes, and I think this case gets somewhat more notoriety because the phishing site has the .com domain and the legitimate one has a .org.
Like it or not, .com adds perceived trustworthiness and works as a branding signal, especially in these times of VCs throwing large amounts of money at branding and buying 3 to 6 letter .com domains, but a small project like 7zip cannot afford that kind of expense.
Lookalike websites serving malware have always existed. So this isn't exactly news. But the browsers are blocking them like they should.
