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...
Hosting an S3 site via Cloudflare From my previous post, you can see that I hosted a slide show on a subdomain on hitbgsec.keithrozario.com. The site is just a keynote presentation exported to html format, which I then hosted on an S3 bucket. The challenge I struggled with, was how to point the domain which I hosted on Cloudflare to the domain hosting the static content. The recommended way is to...
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...
On the 20th of July, Singaporean authorities announced a data breach affecting SingHealth, the country largest healthcare group. The breach impacted 1.5 million people who had used SingHealth services over the last 3 years. Oh boy, another data breach with 1.5 million records … **yawn**. But Singapore has less than 6 million people, so it’s a BIG deal to this island I currently call...
Recently, there was a poorly written article in The New Straits Times, that suggested the Malaysian Police would know if you were watching porn online. Let me cut to the chase, the article is shit. The software in question, aptly named Internet Crime Against Children Child Online Protective Services (ICACCOPS) is used to detect Child Pornography, and Child Pornography only — as the name...
Gov-TLS-Audit got a brand new domain today. No longer is it sharing a crummy domain with sayakenahack (which is still blocked in Malaysia!), it now has a place to call it’s own. The domain cost me a whooping $18.00/yr on AWS, and involved a couple hours of registration and migration. So I felt that while migrating domains, I might as well implement proper security headers as well. Security...
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...
Last week, MyNic suffered a massive outage taking out any website that had a .my domain, including local banks like maybank2u.com.my and even government websites hosted on .gov.my. Here’s a great report on what happened from IANIX. I’m no DNSSEC expert, but here’s my laymen reading of what happened: .my uses DNSSEC Up to 11-Jun,.my used a DNSKEY with key tag:25992 For some...
