Have you upgraded to v14 and Active Directory/LDAP auth to the appliance admin stopped working? Try running this: tmsh modify auth ldap system-auth check-roles-group enabled save sys config Seems that there was a change in how group enumeration happens, and this fix sorts it. You don’t need to reboot or anything, it just works. [Read More]

A pretty cool and easy to follow article on configuring filebeat to monitor your Ubuntu/CentOS boxes from Burnham Forensics is pretty cool. Though, I do have to question any article from a security professional that includes the following line: Elevate to sudo if not done so already: sudo su … let alone in an article about logging! :) [Read More]

While job seeking I’ve been reading the LinkedIn Daily Rundown; I’m not normally one for business news, but it tends to be a good quick thing to catch up on. Today’s instalment was particularly dystopian. Like your job? Sadly it could be automated sooner than you think, according to a new Organisation for Economic Co-operation and Development (OECD) report. Not surprising, really - there’s a lot of process work and drivers out there. [Read More]

A great writeup on how Bansky handles authentication of his artworks. So Banksy created a not-for-profit company, Pest Control, to sell and authenticate his works. The process is fiendishly clever, as Will Ellsworth-Jones writes in his book ‘Banksy: The Man Behind the Wall’: Now, for £65 you can get your Banksy print authenticated. And just to keep the whole thing as jokey as possible, the authentication certificate has stapled to it half a ‘Di faced tenner’, a £10 note faked by Banksy with Lady Diana’s face on it. [Read More]

A friend asked me for help with this one. I hadn’t planned on doing the Plaid CTF but I’m easily dragged into a neat programming challenge. can you guess me Misc (100 pts) Here’s the source to a guessing game: here You can access the server at nc canyouguessme.pwni.ng 12349 Nothing ridiculously simple here, the solution’s obviously in the code… here’s the code that was provided: #! /usr/bin/env python3 from sys import exit from secret import secret_value_for_password, flag, exec print(r"") print(r"") print(r" ____ __ __ ____ __ __ ") print(r" / ___|__ _ _ _\ \ / /__ _ _ / ___|_ _ ___ ___ ___| \/ | ___ ") print(r"| | / _` | '_ \ V / _ \| | | | | _| | | |/ _ \/ __/ __| |\/| |/ _ \ ") print(r"| |__| (_| | | | | | (_) | |_| | |_| | |_| | __/\__ \__ \ | | | __/ ") print(r" \____\__,_|_| |_|_|\___/ \__,_|\____|\__,_|\___||___/___/_| |_|\___| ") print(r" ") print(r"") print(r"") try: val = 0 inp = input("Input value: ") count_digits = len(set(inp)) if count_digits <= 10: # Make sure it is a number val = eval(inp) else: raise if val == secret_value_for_password: print(flag) else: print("Nope.

This was the challenge: The flag is contained in the following attached file. You know how QR codes work right? Flag is in format “word”. (So no flag bit on this one) Challenge by Garry. Attached was a 1.2MB, 20,000 line file which looked like this: I’ve been around a while and the =’s at the end of the lines made me think of base64, so I copied it out into CyberChef and got my first indication I was on the right path: [Read More]

I couldn’t find an easy list when I went looking for these, so I made a list. Key Combination Command Host + R Reset Host + Q Close VM Host + S Settings Host + T Snapshot Host + N Session Information Host + P Pause Host + H ACPI Shutdown View Window Key Combination Command Host + F Fullscreen Host + L Seamless mode Host + C Scaled mode Host + A Adjust Window Size Host + E Take Screenshot Keyboard Key Combination Command Host + End Send Ctrl-Alt-Delete Host + Backspace Send Ctrl-Alt-Backspace [Read More]

I’ve been playing around with stackstorm for a little while now, and wanted to get back into it after a bit of distraction on other things. The idea of automating a lot of my daily repetetive tasks really appeals to me, so I started work on another module today. The end result of today’s head-desking was st2-whois, a pack that does basic whois calls and saves me from having to find the website that works just right for it, or open a shell from a box with the right access.

This article on Naked Security is a little bit calmer than some of the other coverage I’ve seen. If I was doing physical/staff security for a large organisation with a global platform I’d totally be using any intel sources I could find to help improve my results. This has to be the least creepy thing they do with thier data. What’s unique about Facebook’s approach to BOLOs is that it doesn’t just disseminate a list of names to security staff. [Read More]

I really like this idea from a longer post about the ethics of blogging by Brett Terpstra I sometimes wish that job résumés and Tinder profiles required an appendix of all of the comments a person has left on other’s work in the last year. You can learn a lot about a person from how they approach offering criticism when it’s not face to face. Anonymity’s a mess, I’m thankful I seem to live on a nicer part of the internet most of the time, more through lack of exposure. [Read More]
