One of the references in his post, which resonated with me, is a quote attributed to Steve Jobs:

Life can be much broader once you discover one simple fact: Everything around you that you call life was made up by people that were no smarter than you. And you can change it, you can influence it…Once you learn that, you’ll never be the same again.

At the end Mikey concludes with the endless opportunity to get involved in public service. However, his words hold just as true in any other context.

Don’t wait to be asked … Decisions are made by those who show up.

How To Avoid Task Saturation http://www.leonelson.com/2017/01/16/how-to-avoid-task-saturation/ http://www.leonelson.com/2017/01/16/how-to-avoid-task-saturation/#respond Tue, 17 Jan 2017 01:14:37 +0000 http://www.leonelson.com/?p=2828 J.D. Meier talks about three solutions on “How To Avoid Task Saturation”, checklists, cross-checks and mutual support.

Solution #1: Checklists

The key here is the checklists are vital to reducing overload and helping remind you of key actions.

I’m a fan of checklists, not only because of how it helps avoid task saturation, but also because if implemented and used correctly, it has proven to be a great tool at removing inefficiencies in processes. Atul Gawande’s, The Checklist Manifesto, provides a number of examples on how various industries have successfully implemented checklists as a method to getting things done right and at the same streamlining complex processes.

No More Ransom is an international initiative that shows the value of public-private cooperation when taking serious action cybercrime. This collaboration goes beyond geographical borders. The main aim of the project is to share knowledge and educate users across the world on how to prevent ransomware attacks. We believe that it will eventually lead to support for repairing the damage caused to victims all around the globe. By restoring access to their systems, we empower users by showing them they can take action and avoid rewarding criminals with a ransom payment.

Inspecting a PDF File http://www.leonelson.com/2016/04/15/inspecting-pdf-file/ http://www.leonelson.com/2016/04/15/inspecting-pdf-file/#respond Fri, 15 Apr 2016 11:02:00 +0000 http://www.leonelson.com/?p=2690 I recently had to complete some work with inspecting a PDF file for malicious content. This was an interesting experience so I thought I’d share the approach I took to review the file from a sandboxed environment:

1. Start with using a service such as virustotal.com, scanii.com, metadefender.com to scan the file

2. Use Adobe Acrobat to browse the internal PDF structure. Launch the PreFlight Tool (Print Production > Preflight) and then under Options select Browse Internal PDF Structure.

3. Use an Adobe PDF meta data application to inspect the file. Here are some I used that were quite helpful:

peepdf.py – PeePDF is a Python based tool to explore PDF files

pdfid.py – PDFID is a Python based tool to scan the file looking for certain PDF keywords. For e.g., does the file contain JavaScript or execute an action when opened

pdf-parser.py – PDF-Parser is a Python based tool to parse a PDF document and identify the fundamental elements used in the file.
