Just a collection of stuff (mostly from my old blog)

Keith’s on #HITBGSEC

K

I haven’t blogged in a long while — but I have a good(ish!) excuse. I spent most of August prepping for the #HITBGSEC conference in Singapore. It was my first time presenting at a security conference, and I had an absolute blast. The output of the countless hours I spent is in the embedded youtube video below, and the presentation material can downloaded here[.key] and a html version...

Why my people will never be Ministers

W

As Malaysians woke up today, to a brand new cabinet of Ministers, many have already begun expressing their dissatisfaction on the lineup. I know better than to wade into these politically charged discussions — but I will point out that my people have long been overlooked for Ministerial positions. Who are ‘my people’ you ask… Hackers. Or if you prefer a less negative word...

Gov TLS Audit has a website!

G

Gov TLS Audit finally has a website to complement the API. I used the services of a guy from fiverr to code the site, it isn’t the best design in the world, but it’s good enough for now. The site allows you to query a site and view the historical details of a particular .gov.my website. The full list of .gov hostnames can be found here. It also links to the full daily scan outputs (in...

First I deleted my most popular tweet — then I deleted 2000 more.

F

Two weeks ago, I rage-tweeted something regarding Malaysian politics that got a lot more viral than I liked (I’ve censored out the profanity for various reasons, most notably, there are teenagers who read this blog). It was a pointless collection of 200 characters, that somehow resonated with people enough to be shared across social media. Obviously, since it was me, the tweet was filled...

Why we need centralized breach notification

W

Let’s start with the basics. Data Breaches are common — and will continue to be the norm. How the App Economy and Big Data ruined it As we shifted towards the ‘App-Economy’ and ‘Big-Data’ (circa 3 years ago), consumers begun sharing more data with more apps. Everyone and their granny, wanted to create a new app, and everyone was told to collect as much data as...

I scanned 1000 government sites, what I found will NOT shock you

I

Previously, I moaned about dermaorgan.gov.my, a site that was probably hacked but was still running without basic TLS. This is unacceptable, that in 2018, we have government run websites, that ask for personal information, running without TLS. So I decided to check just how many .gov.my sites actually implemented TLS, and how many would start being labled ‘not secure’ by Google in...

Another Day, Another breach

A

220,000 is a lot of people. It’s the population of a small town like Taiping, and roughly twice the capacity of Bukit Jalil Stadium. Yet today, a data breach of this size, barely registers in the news-cycle. After all, the previous data breach was 200 times bigger, and occurred just 3 months ago. How could we take seriously something that occurs so frequently, and on a scale very few...

That long post about Data breaches (you never wanted to read!)

T

Part 1: An intro to Data Breaches Let’s start with some basics. What is a Data Breach? According to┬áVerizon, a data breach is when you’ve confirmed that data has been lost to an attacker, while a data incident is merely something that ‘may’ result in a breach. An incident is when a laptop goes missing from your company’s office. A breach is when the data on that...

Part 8: False prepaid registrations

P

Consider this a bonus piece from my long thoughts about data breaches. You might the older post before reading this. So let’s dive in. The telco breach was a giant hairball of issues, and one of the strands in the hairball is false prepaid registrations. Immediately after releasing sayakenahack, people reported that they were seeing additional numbers linked to their mykad numbers. From...

Writing Millions of rows into DynamoDB

W

While designing sayakenahack, the biggest problem I faced was trying to write millions of rows efficiently into DynamoDB. I slowly worked my way up from 100 rows/second to around the 1500 rows/second range, and here’s how I got there. Work with Batch Write Item First mistake I did was a data modelling error. Sayakenahack was supposed to take a single field (IC Number) and return the results...
