Hello IT Pro,
Welcome back to IT Pro Tuesday!
First item this week is an alert about a new form of cyber attack called email conversation thread hijacking that handily thwarts your sage advice to users that they should only open messages from people they know. If you are unfamiliar with how it works, you can read more here.
We’re looking for your favorite tips to share with the community. Please let us know those that help you do things more easily so you get better at your job!
As always, we’re updating the full, searchable list on our website here. Enjoy.
But on with this week's tools...! Here are the most-interesting items that have come across our desks, laptops and phones this week. Hornetsecurity has no known affiliation with any of these unless we explicitly state otherwise.
Let's Debug provides a set of tests to help figure out why you might not be able to issue a certificate for Let's Encrypt. You simply enter the domain and validation method to identify problems with basic DNS setup, problems with nameservers, rate limiting, networking issues, CA policy issues and common website misconfigurations. Kindly recommended by Perrydiculous.
The Bash Hackers Wiki provides human-readable documentation and information on GNU Bash so users don't have to read the entire Bash manpage. It's not intended for newbies, but a great resource for those already familiar with Bash. A shout out to whetu for directing us to this one.
A Free Tool
yEd Graph Editor is an application for generating high-quality diagrams either manually or by importing your data. Even large data sets can be arranged by the automatic layout algorithms with a single click. Runs on all major platforms. Thanks go to jmbpiano for the suggestion!
Schneier on Security is a blog on security issues by a fellow and lecturer at Harvard's Kennedy School and a board member of EFF. bdzer0 appreciates it for "high level monthly security/encryption."
Another Free Tool
Hiren's Boot CD includes pretty much everything you need to recover a dead OS or accidentally deleted or lost files. TheGreaterAjax describes it as a "One stop shop for basically anything. From loading antivirus before boot, or imaging a drive that's on it's last leg. Lots and lots of tools built-in, and it has a desktop gui as well."
P.S. Bonus Free Tools
Cmder was designed to fill the void of nice console emulators on Windows. lescompa explains, "Cmder is very customizable (tabbed interface) and a great console/terminal emulation replacement for most cli work instead of Putty/Powershell/DOS box. There is also a 'mini' version, which is USB portable."
Etcher is an open-source SD card burner app with a simple, elegant GUI that makes drive selection obvious to avoid accidentally wiping your hard-drive. Extensible and works on any platform. Suggested by cra2y_hibare, who likes it for single boot.
Have a fantastic week and as usual, let us know any comments.
