Keith is an architect by day, blogger by night. He’s responsible for all the content on this blog, and irresponsible for everything else.
First a definition. A lambda function is a service provided by aws that runs code for you without the introducing the complexity of provisioning servers of managing Operating Systems. It belongs in a category of architectures called serverless architectures. There’s a whole slew of folks trying to define with is serverless, but my favorite definition is this. Serverless means No Server...
As a company, Grab has done enormously well for itself, and naturally will be the target of some hate.
But I think there's a deeper issue with Grab that needs addressing before it becomes an unsolvable problem.
Android TV boxes, are computers that stream content from the internet onto your TV. The difference between them and your smart-phone is that it has a HDMI connector to your TV, and it usually comes pre-loaded with software to illegally stream content. While the boxes themselves, are general purpose computers running Android (the most popular OS today), the real focus of any regulation should be...
I’m still deep in my lambda love affair. Here’s my talk at the AWS meetup in SG on Lambda layers :
2018 in review I started the year building out govScan.info, a site that audits .gov.my websites for TLS implementation. Overall I curated a list of ~5000 Malaysian government domains through various OSINT and enumeration techniques and now use that list to scan them daily. The project stalled around Jun/July, and it’s basically on auto-pilot till I figure out what to do. The scans still...
Shutting Down!! Sayakenahack was undoubtedly the highlight of my 2017. If you’ve come from sayakenahack.com, I’m sorry but I’ve shutdown the site :(. I learnt so much from it, and it was even my ticket for presenting at Hack In the Box Singapore … But all good things must come to an end, there’s no point having a site that does nothing but consume my hosting charges...
Over the past few weeks, I’ve been toying with lambda functions and thinking about using them for more than just APIs. I think people miss the most interesting aspect of serverless functions — namely that they’re massively parallel capability, which can do a lot more than just run APIs or respond to events. There’s 2-ways AWS let’s you run lambdas, either via...
GitHub Webhooks with Serverless
Just because you have webhook, doesn’t mean you need a webserver.
With serverless AWS Lambdas you’ve got a free (as in beer) and always on ability to receive webhooks callbacks without the need for pesky servers. In this post, I’ll setup a serverless solution to accept incoming POST from a GitHub webhook.
DNS Queries on GovScan.Info This post is a very quick brain-dump of stuff I did over the weekend, in the hopes that I don’t forget it :). Will post more in-depth material if time permits over the weekend. govScan.info, a site I created as a side hobby project to track TLS implementation across .gov.my websites — now tracks DNS records as well. For now, I’m only tracking MX, NS...
The security community has been abuzz with an absolutely shocker of story from Bloomberg. The piece reports that the Chinese Government had subverted the hardware supply chain of companies like Apple and Amazon, and installed a ‘tiny chip’ on motherboards manufactured by a company called Supermicro. What the chip did — or how it did ‘it’ was left mostly to the...
