Major amplification attacks from UDP port 11211

CC BY-SA 2.0 image by David Trawin Over last couple of days we’ve seen a big increase in an obscure amplification attack vector – using the memcached protocol, coming from UDP port 11211. In the past, we have talked a lot about amplification attacks happening on the internet. Our most recent two blog posts on this subject were: The general idea behind all amplification attacks is the same. An IP-spoofing capable attacker sends forged requests to a vulnerable UDP server.…

Deep Neural Networks for Survival Analysis Based on a Multi-Task Framework

Stephane Fotso, Data Scientist at Square, recently developed a new method to calculate survival functions. Here’s his paper describing the process. Deep Neural Networks for Survival Analysis Based on a Multi-Task Framework was originally published in Square Corner Blog on Medium, where people are continuing the conversation by highlighting and responding to this story.

Cosmic space invaders or victims of galactic eviction? — ScienceDaily

An international team of astronomers led by the Max Planck Institute for Astronomy (MPIA) has made a surprising discovery about the birthplace of groups of stars located in the halo of our Milky Way galaxy. These halo stars are grouped together in giant structures that orbit the center of our galaxy, above and below the flat disk of the Milky Way. Researchers thought they may have formed from debris left behind by smaller galaxies that invaded the Milky Way in…

You Are Your Own Best Hype Person – Square Corner Blog – Medium

Learn how to accurately and effectively advocate for yourself and grow in your career by recording your accomplishments. At some point in your career, you’re going to have to prove to someone that you’re worth it: worth hiring, worth promoting, worth the raise, worth taking a risk on. If you’re lucky, you might have someone who has seen your work first hand, who believes in you and can vouch for you. Gif of Blanche from TV show The Golden Girls…

Global levels of ethane and propane in the atmosphere have been underestimated by more than 50% — ScienceDaily

Global levels of ethane and propane in the atmosphere have been underestimated by more than 50%, new research involving scientists at the University of York has revealed. These hydrocarbons are particularly harmful in large cities where, through chemical reactions with emissions from cars, they form ozone — a greenhouse gas which is a key component of smog and directly linked to increases in mortality. Ethane and propane escape into the air from leaks during natural gas extraction and distribution, including…

Starting as an Engineering Manager

I joined Cloudflare last week as an Engineering Manager, having previously spent 4 years working as the head of the software engineering community in the UK Government’s Digital Service (GDS). You only get one chance to be a new starter at each new place, so it’s important to make the most of the experience. Also, the job of Engineering Manager is different in every organisation, so it’s important to understand what the expectations and need for the role is in…

Wayfair at WSDM: Conference Recap

At the beginning of February, I attended one of ACM’s premier conferences, WSDM 2018 in Los Angeles. Apart from the Hollywood-style banquet dinner on a boat, I was looking forward to the opportunity to talk through ideas with some of the brightest minds in the world from both academia and industry. Here are my nuggets from the conference – Multimodal Learning As humans we leverage some subset of our senses – hearing, sight, touch, etc., when we learn new skills. Recall…

Using Cloudflare Workers to identify pwned passwords

Last week Troy Hunt launched his Pwned Password v2 service which has an API handled and cached by Cloudflare using a clever anonymity scheme. The following simple code can check if a password exists in Troy’s database without sending the password to Troy. The details of how it works are found in the blog post above. use strict; use warnings; use LWP::Simple qw/$ua get/; $ua->agent('Cloudflare Test/0.1'); use Digest::SHA1 qw/sha1_hex/; uc(sha1_hex($ARGV[0]))=~/^(.{5})(.+)/; print get("https://api.pwnedpasswords.com/range/$1")=~/$2/?'Pwned':'Ok', "n"; It’s just as easy to implement the…

Engineering Ethics Blog: Sorting Souls with fMRI

In the March issue of Scientific American, brain-imaging expert John Gabrieli says that we can now use functional magnetic-resonance-imaging (fMRI) technology to predict whether depressed patients will benefit from certain therapies, whether smokers will be able to quit, and whether criminals will land back in jail soon.  But he leaves unanswered some questions he raises—namely, if we find that we can reliably obtain this kind of information, what should we do with it? First, a brief explanation of what fMRI…
