Navy story time again. Grab that coffee and fire up Kali, the theme is security.
So, when I got promoted to Lieutenant Jr. I had to attend a 1-year school inside my nostalgic Naval Academy... BUT! I was wiser, I was older... and I was bored. Like, really bored. What could go wrong? Well, all my fellow officers were bored too, so they started downloading/streaming/torrenting like crazy, and I had to wait for hours for the Kali updates to download, so...
mdk3 wlan0mon -d
I had this external wifi atheros card with two antennae and kicked all of them off the wifi. Some slightly smarter ones plugged cables on the net, and kept going, enjoying much faster speeds. I had to go to the bathroom, and once I returned they had unplugged the card. That kind of pissed me off, since they also thought it would be funny to hide it, along with the mouse.
But, oh boy, they had no idea what supreme asshole I can be when I am irked.
So, arpspoof it is. Turns out, there were no subnetworks, and the broadcast domain was ALL of the academy. That means I shut EVERYONE off, except me. Hardware was returned in 1 minute with the requested apologies, but fuck it, I kept the whole academy off the net for 6 hours. The sysadmin ran around like crazy, because nothing was working. Not even the servers.
I finally took pity on the guy (he had gotten the duties of sysadmin when the previous sysad died, so think about that) and he almost assaulted me when I told him. As it turned out, the guy never had any training or knowledge on security, so I had to show him a few things, and point him to where he could study about the rest. But still, some selective arp poison on select douchebags was in order...
Needless to say, people were VERY polite to me after that. And the net speed was up again, so I got bored. Again. So I started scanning the net.
To be continued...3 -
Paranoid Developers - It's a long one
Backstory: I was a freelance web developer when I managed to land a place on a cyber security program with who I consider to be the world leaders in the field (details deliberately withheld; who's paranoid now?). Other than the basic security practices of web dev, my experience with Cyber was limited to the OU introduction course, so I was wholly unprepared for the level of, occasionally hysterical, paranoia that my fellow cohort seemed to perpetually live in. The following is a collection of stories from several of these people, because if I only wrote about one they would accuse me of providing too much data allowing an attacker to aggregate and steal their identity. They do use devrant so if you're reading this, know that I love you and that something is wrong with you.
That time when...
He wrote a social media network with end-to-end encryption before it was cool.
He wrote custom 64kb encryption for his academic HDD.
He removed the 3 HDD from his desktop and stored them in a safe, whenever he left the house.
He set up a pfsense virtualbox with a firewall policy to block the port the student monitoring software used (effectively rendering it useless and definitely in breach of the IT policy).
He used only hashes of passwords as passwords (which isn't actually good).
He kept a drill on the desk ready to destroy his HDD at a moments notice.
He started developing a device to drill through his HDD when he pushed a button. May or may not have finished it.
He set up a new email account for each individual online service.
He hosted a website from his own home server so he didn't have to host the files elsewhere (which is just awful for home network security).
He unplugged the home router and began scanning his devices and manually searching through the process list when his music stopped playing on the laptop several times (turns out he had a wobbly spacebar and the shaking washing machine provided enough jittering for a button press).
He brought his own privacy screen to work (remember, this is a security place, with like background checks and all sorts).
He gave his C programming coursework (a simple messaging program) 2048 bit encryption, which was not required.
He wrote a custom encryption for his other C programming coursework as well as writing out the enigma encryption because there was no library, again not required.
He bought a burner phone to visit the capital city.
He bought a burner phone whenever he left his hometown come to think of it.
He bought a smartphone online, wiped it and installed new firmware (it was Chinese; I'm not saying anything about the Chinese, you're the one thinking it).
He bought a smartphone and installed Kali Linux NetHunter so he could test WiFi networks he connected to before using them on his personal device.
(You might be noticing it's all he's. Maybe it is, maybe it isn't).
He ate a sim card.
He brought a balaclava to pentesting training (it was pretty meme).
He printed out his source code as a manual read-only method.
He made a rule on his academic email to block incoming mail from the academic body (to be fair this is a good spam policy).
He withdraws money from a different cashpoint everytime to avoid patterns in his behaviour (the irony).
He reported someone for hacking the centre's network when they built their own website for practice using XAMMP.
I'm going to stop there. I could tell you so many more stories about these guys, some about them being paranoid and some about the stupid antics Cyber Security and Information Assurance students get up to. Well done for making it this far. Hope you enjoyed it.26 -
Walk into mall, bring my child to kids zone. They have free wifi 🤤
Accessing -> Scanning -> Got Ya! -> Brute Force -> Cracked!
There you're.
Now I can monitoring my kid while reading rant!
Just normal day in my life6 -
A few years ago I was in high school and used to have a small reputation of hacking things. I could hack, just would never hack any school networks or systems (reputation + notice that there was a breach is a bad combo since everyone would immediately suspect you).
Anyways one day the networks internet connection went down in the school district and I was the only one who used a laptop to take notes. So I quickly opened the terminal and ran Wireshark and said to the person to my right "see that button there? yeah I programmed this last night. anytime I press it I can shut down the network so the teacher can't reach her files (she famously only saved them online). *Long dramatic press* Wireshark started scanning the network so all the numbers and lines were going crazy as it viewed the packet info "Now just wait", soon the whole class knew what I had done through whispers and lo and behold a few minutes later and the teacher couldn't reach her files.
Everyone loved me for the rest of the year for saving them from the homework for the week the wifi network was out since it also ended up having to cancel two tests in the class, and a lot more homework and tests in all their other classes. Solidified my reputation and no one fucked with me from that day on. -
And just when you like Linux a little too much, it bites you in the ass to remind you why the year of the Linux desktop never happened.
Wifi printer is installed, CUPS test page works, even scanning works. But printing anything else results in the printer spitting out raw postscript with a few random lines per page.
Great. Looks like I'll have to print to PDF, then go to a copy shop and print because printing under Linux is still an unsolved issue.
And yes, that would have worked even with Windows 10. Fuck.24 -
Hey Google
Did you know that
uuuuuuh
you can go choke on my already available location that my phone already shows?1 -
Gotta love the IoT.
They set up a new surveillance camera in the company, that can stream live footage over the network and that little shit picked the IP adress of a coworker one day AFTER being set up.
Hurray for static routing. Hurray to the person who didn't disable DHCP on the router (Should probably configure my PC to use a static IP as well lel)
Anyways, this happened outta nowhere when I, the only guy who knows shit about IT and is usually present at yhe office, wasn't there and could not connect remotely.
The other, remote programmer, who set up the network, could guide the coworker to get a new IP but, he was worried that we got ourselves an intruder.
Since nobody told me yet that we (should) have static routing, I thought there was a mastermind at work who could get into a network without a wifi-access point and spoof the coworker in order to access the some documents.
The adrenaline rush was real 😨
Scanning the network with nmap solved the mystery rather quickly but thought me that I need to set up a secure way to get remote access on the network.
I would appreciate some input on the set up I thought of:
A raspberry Pi connected to a vpn that runs ssh with pw auth disabled and the ssh port moved.
Would set up the vpn in a similar fashion.
