!Story
The day I became the 400 pound Chinese hacker 4chan.
I built this front-end solution for a client (but behind a back end login), and we get on the line with some fancy European team who will handle penetration testing for the client as we are nearing dev completion.
They seem... pretty confident in themselves, and pretty disrespectful to the LAMP environment, and make the client worry even though it's behind a login the project is still vulnerable. No idea why the client hired an uppity .NET house to test a LAMP app. I don't even bother asking these questions anymore...
And worse, they insist we allow them to scrape for vulnerabilities BEHIND the server side login. As though a user was already compromised.
So, I know I want to fuck with them. and I sit around and smoke some weed and just let this issue marinate around in my crazy ass brain for a bit. Trying to think of a way I can obfuscate all this localStorage and what it's doing... And then, inspiration strikes.
I know this library for compressing JSON. I only use it when localStorage space gets tight, and this project was only storing a few k to localStorage... so compression was unnecessary, but what the hell. Problem: it would be obvious from exposed source that it was being called.
After a little more thought, I decide to override the addslashes and stripslashes functions and to do the compression/decompression from within those overrides.
I then minify the whole thing and stash it in the minified jquery file.
So, what LOOKS from exposed client side code to be a simple addslashes ends up compressing the JSON before putting it in localStorage. And what LOOKS like a stripslashes decompresses.
Now, the compression does some bit math that frankly is over my head, but the practical result is if you output the data compressed, it looks like mandarin and random characters. As a result, everything that can be seen in dev tools looks like the image.
So we GIVE the penetration team login credentials... they log in and start trying to crack it.
I sit and wait. Grinning as fuck.
Not even an hour goes by and they call an emergency meeting. I can barely contain laughter.
We get my PM and me and then several guys from their team on the line. They share screen and show the dev tools.
"We think you may have been compromised by a Chinese hacker!"
I mute and then die my ass off. Holy shit this is maybe the best thing I've ever done.
My PM, who has seen me use the JSON compression technique before and knows exactly whats up starts telling them about it so they don't freak out. And finally I unmute and manage a, "Guys... I'm standing right here." between gasped laughter.
If only it was more common to use video in these calls because I WISH I could have seen their faces.
Anyway, they calmed their attitude down, we told them how to decompress the localStorage, and then they still didn't find jack shit because i'm a fucking badass and even after we gave them keys to the login and gave them keys to my secret localStorage it only led to AWS Cognito protected async calls.
Anyway, that's the story of how I became a "Chinese hacker" and made a room full of penetration testers look like morons with a (reasonably) simple JS trick.

It's been a while DevRant!
Straight back into it with a rant that no doubt many of us have experienced.
I've been in my current job for a year and a half & accepted the role on lower pay than I normally would as it's in my home town, and jobs in development are scarce.
My background is in Full Stack Development & have a wealth of AWS experience, secure SaaS stacks etc.
My current role is a PHP Systems Developer, a step down from a senior role I was in, but a much bigger company, closer to home, with seemingly a lot more career progression.
My job role/descriptions states the following as desired:
PHP, T-SQL, MySQL, HTML, CSS, JavaScript, Jquery, XML
I am also well versed in various JS frameworks, PHP Frameworks, JAVA, C# as well as other things such as:
Xamarin, Unity3D, Vue, React, Ionic, S3, Cognito, ECS, EBS, EC2, RDS, DynamoDB etc etc.
A couple of months in, I took on all of the external web sites/apps, which historically sit with our Marketing department.
This was all over the place, and I brought it into some sort of control. The previous marketing developer hadn't left and AWS access key, so our GitLabs instance was buggered... that's one example of many many many that I had to work out and piece together, above and beyond my job role.
Done with a smile.
Did a handover to the new Marketing Dev, who still avoid certain work, meaning it gets put onto me. I have had a many a conversation with my line manager about how this is above and beyond what I was hired for and he agrees.
For the last 9 months, I have been working on a JAVA application with ML on the back end, completely separate from what the colleagues in my team do daily (tickets, reports, BI, MI etc.) and in a multi-threaded languages doing much more complicated work.
This is a prototype, been in development for 2 years before I go my hands on it. I needed to redo the entire UI, as well as add in soo many new features it was untrue (in 2 years there was no proper requirements gathering).
I was tasked initially with optimising the original code which utilised a single model & controller :o then after the first discussion with the product owner, it was clear they wanted a lot more features adding in, and that no requirement gathering had every been done effectively.
Throughout the last 9 month, arbitrary deadlines have been set, and I have pulled out all the stops, often doing work in my own time without compensation to meet deadlines set by our director (who is under the C-Suite, CEO, CTO etc.)
During this time, it became apparent that they want to take this product to market, and make it as a SaaS solution, so, given my experience, I was excited for this, and have developed quite a robust but high level view of the infrastructure we need, the Lambda / serverless functions/services we would want to set up, how we would use an API gateway and Cognito with custom claims etc etc etc.
Tomorrow, I go to London to speak with a major cloud company (one of the big ones) to discuss potential approaches & ways to stream the data we require etc.
I love this type of work, however, it is 100% so far above my current job role, and the current level (junior/mid level PHP dev at best) of pay we are given is no where near suitable for what I am doing, and have been doing for all this time, proven, consistent work.
Every conversation I have had with my line manager he tells me how I'm his best employee and how he doesn't want to lose me, and how I am worth the pay rise, (carrot dangling maybe?).
Generally I do believe him, as I too have lived in the culture of this company and there is ALOT of technical debt. Especially so with our Director who has no technical background at all.
Appraisal/review time comes around, I put in a request for a pay rise, along with market rates, lots of details, rates sources from multiple places.
As well that, I also had a job offer, and I rejected it despite it being on a lot more money for the same role as my job description (I rejected due to certain things that didn't sit well with me during the interview).
I used this in my review, and stated I had already rejected it as this is where I want to be, but wanted to use this offer as part of my research for market rates for the role I am employed to do, not the one I am doing.
My pay rise, which was only a small one really (5k, we bring in millions) to bring me in line with what is more suitable for my skills in the job I was employed to do alone.
This was rejected due to a period of sickness, despite, having made up ALL that time without compensation as mentioned.
I'm now unsure what to do, as this was rejected by my director, after my line manager agreed it, before it got to the COO etc.
Even though he sits behind me, sees all the work I put in, creates the arbitrary deadlines that I do work without compensation for, because I was sick, I'm not allowed a pay rise (doctors notes etc supplied).
What would you do in this situation?4 -
AAAH, fucking aws. Why the fuck do you make documentation if it doesnt even make sense. I struggeled for hours to let your cock sucking Cognito work and I'm still fucking stuck. Why is there no proper documentation or tutorial available for nodejs. This pisses me the fuck off. I hate this piece of shit.
Ah... I feel better now. -
Auth0 and Okta merge.... Is Cognito the only other major player here? This merge now makes an Auth monopoly!7

Finally made my node production server stable enough that I could focus on writing tests*. I start by setting up docker, mocking cognito, preparing the database and everything. Reading up on Node test suites and following a short tut to set up my first unit test. Didn't go smoothly, but it's local and there are no deadlines so who cares. 4 days later, first assert.equal(1+1, 2) passes and I'm happy.
I start writing all sorts of tests, installing everything required into "devDependancies," and getting the joy of having some tests pass on first try with all asserts set up, feels good!
I decide to make a small update to production, so I add a test, run and see it fail, implement the feature, re-run and, it passes!
I push the feature to develop, test it, and it works as intended. Merge that to master and subsequently to one of my ec2 production servers**, and lo and behold, production server is on a bootloop claiming it "Cannot find module `graphql`". But how? I didn't change any production dependencies, and my package lock json is committed so wth?
I google the issue, but can't find anything relevant. The only thing that I could guess was that some dependencies (including graphql) were referenced*** in both, prod and dev, and were omitted when installed on a prod NODE_ENV, but googling that specific issue yielded no results, and I would have thought npm would be clever enough to see that and would always install those dependencies (spoiler: it didn't for me).
With reduced production capacity (having one server down) I decided to npm uninstall all dev dependencies anyway and see what happens. Aaaaand it works.....
So now I have a working production server, but broken local tests, and I'm not sure why npm is behaving like this...
* Yes I see the irony.
** No staging because $$$, also this is a personal project.
*** I am not directly referencing the same thing twice, it's probably a subdependency somewhere.2 -
Staring at a dozen cognito errors, spending two days sifting through AWS, only to find that the test DB is fucking empty...1

I hate the company (agency) I moved to...I've negotiated good pay and the project for cutting edge medical product which will change the world (cancer diagnose and it actually works).
Now the dark side I've got shit tier laptop which I don't want, overtime is payed 30% less, all the people in the agency from development team don't know shit and are mostly I would call them juniors (of course who would with enough seniority work with shit hardware and almost not payed overtime), only tap water and since this is the old part of town you instantly get sick, they treat people like shit.
The product dark side. We are actually working on crm for doctors to input patient data, we cannot have any real data because we are the agency people, product is being led by the guy who has 0 production experience (they choose the database basically with coin toss and emulated the mongodb in postgress with jsnob, they don't know how to build their own auth system hence my previous rant about b2c, they are using cognito and now moving to auth0 which probably won't fit their need because a lot of stuff needs to be custom), they are choosing every hipe tech out there without any prior experience. It's chaos...
I'm trying to guide them but i think this will be a huge expensive failure and that i need to leave asap.
There I feel better now, moral of the story, choose startups wisely.1 -
Trying to stand up an app using AWS "serverless" and Cognito, but feel like I've shown up to a seminar on time shares by multi-level-marketers. Has anyone really used this?1
