Founder and president of Cyber Saiyan - www.cybersaiyan.it - a no profit organization founded to promote social initiatives to spread cyber security and ethical hacking culture; Cyber Saiyan organizes RomHack - www.romhack.io - a cyber security conference held yearly in Rome.
I'm heading "Information, systems and network Security" at ENAV, the italian air navigation service provider.
Sometimes I write about open source, security and boring stuff on my blog www.scubarda.com
Squid can be configured to make SSL/TLS inspection (aka HTTPS interception) so the proxy can decrypt proxied traffic (Squid calls this feature ssl bump).
Afaik the Squid package included in the Linux distros is not compiled with SSL/TLS inspection support but the good news is that diladele (its github repo and Websafetydocumentation are useful resources) provides packages for Ubuntu and Centos, recompiled (you can do by yourself) with support for HTTPS filtering and SSL/TLS inspection. This means that we have just to configure Squid. Not an easy task anyway 🙂
I provide to you a working config, follow next steps.
I was very busy organizing the second edition of RomHack, the free cyber security conference made with ❤ by Cyber Saiyan – the non-profit organization I founded 2 years ago – that took place in Rome past 28th of September.
We had an incredible lineup with italian and international speakers coming from around the world and 400 attendees. Not just the conference; at the end of the conf 16 team played the on site Capture The Flag.
Phishing is a common attack characterized by simplicity and effectiveness; phishing emails are used to drop malware, cryptolocker, steal credentials… and they are successfull just because Dave. I suggest reading this page to understand “the existing forms of phishing attacks and the currently available mitigations“.
Companies – hopefully – train their employees with internal phishing campaigns; in this post I show how we can build a simple office document that – once opened – sends information to an external server. We can use the document – along with Gophish or other tools – to build our own phishing campaign and test our organization exposure to phishing, teaching people and rising awareness.
I use twitter to follow a lot of good feeds but often I need to follow twitter threads for new replies to have a fast and complete view of complex threads even if I’m not cited or the tweet owner.
I did some search and found a python script from @edu on github that was a good starting point. I learned that twitter API doesn’t allow to get all the replies to a tweet but can be used to search for replies to a given tweet and replies to any reply as well. Good.
So starting from @edu code I wrote Twitter Scraper, a project – made of 2 scripts
twitter-scraper.py to get a complete list of twitter threads replies so you can have a fast and complete view of complex threads even if you are not the owner or you are not cited in all the tweet branches [video]
In this post I just show what domains you need to enable to authorize access to telegram and whatsapp web sites behind your corporate proxy. This is useful when you need to allow – like me – just a subset of your users to access it.
