According to Wikipedia, Typosquatting, “is a form of cybersquatting, and possibly brandjacking which relies on mistakes such as typos made by Internet users when inputting a website address into a web browser.” This same technique can be used to bypass email protections and get malicious mail into mailboxes with domains that are, or look like, they are authentic.

To begin, create a free account to gain access to the higher usage limit of 50,000 API requests per month. After creating an account, access your dashboard from https://ipinfo.io/account, scroll down to the bottom, and grab your access token. You’ll need this later.
When someone’s credentials get compromised by spammers, you’re sure to see an increase in logins from locations that aren’t…
I hate winter. I need up-to-date data every couple of days telling me exactly how much more of winter I have to endure. I don’t trust foreign and/or unproven sources for this knowledge, I had to create something myself.
Here’s what I used:
Allocate a folder or something, example
/var/www/html/spring, change to it, and download the plugin:
➜ ~ unzip jquery.countdown-2.2.0.zip
➜ ~ cd jquery.countdown-2.2.0
