How to PWN FoMo3D, a beginners guide : ethereum
I found out about FoMo3D today and saw that it's an pyramid game holding an insane $12M stash currently. Looking through the code, it's multiple contracts totaling thousands of lines of code. Let's be honest, $12M inside thousands of lines of Solidity... that's asking for it.

Hacker Curriculum
This site is intended to serve Computer Science researchers and teachers as a guide to the rich and diverse world of ethical hacker publications and to raise awareness of state-of-the-art research ideas that originate in the hacker community.

There are several excellent academic research labs that are aware of hacker research and appreciate hacker skills. We are grateful for your support! Unfortunately, to many others fellow academics the hacker community is a stereotyped unknown that is both distrusted and discounted. We would like to fix this and make sure that the ethical hacker community gets acknowledged for what it is - a national resource of great value.

Xerox scanners/photocopiers randomly alter numbers in scanned documents [D. Kriesel]
In this article I present in which way scanners / copiers of the Xerox WorkCentre Line randomly alter written numbers in pages that are scanned. This is not an OCR problem (as we switched off OCR on purpose), it is a lot worse – patches of the pixel data are randomly replaced in a very subtle and dangerous way: The scanned images look correct at first glance, even though numbers may actually be incorrect. Without a fuss, this may cause scenarios like:

All watched over by machines – a review of Yasha Levine’s “Surveillance Valley” | LibrarianShipwreck
Surveillance Valley is a troubling book, but it is an important book. It smashes comforting myths and refuses to leave its readers with simple solutions. What it demonstrates in stark relief is that surveillance and unnerving links to the military-industrial complex are not signs that the Internet has gone awry, but signs that the Internet is functioning as intended.

Security and Game Theory: Algorithms, Deployed Systems, Lessons Learned: Milind Tambe: 9781107096424: Amazon.com: Books
Global threats of terrorism, drug-smuggling, and other crimes have led to a significant increase in research on game theory for security. Game theory provides a sound mathematical approach to deploy limited security resources to maximize their effectiveness. A typical approach is to randomize security schedules to avoid predictability, with the randomization using artificial intelligence techniques to take into account the importance of different targets and potential adversary reactions. This book distills the forefront of this research to provide the first and only study of long-term deployed applications of game theory for security for key organizations such as the Los Angeles International Airport police and the U.S. Federal Air Marshals Service. The author and his research group draw from their extensive experience working with security officials to intelligently allocate limited security resources to protect targets, outlining the applications of these algorithms in research and the real world. The book also includes professional perspectives from security experts Erroll G. Southers; Lieutenant Commander Joe DiRenzo III, U.S. Coast Guard; Lieutenant Commander Ben Maule, U.S. Coast Guard; Erik Jensen, U.S. Coast Guard; and Lieutenant Fred S. Bertsch IV, U.S. Coast Guard.

What It’s Like to Live in a Surveillance State - The New York Times
This personal information, along with your biometric data, resides in a database tied to your ID number. The system crunches all of this into a composite score that ranks you as “safe,” “normal” or “unsafe.”Based on those categories, you may or may not be allowed to visit a museum, pass through certain neighborhoods, go to the mall, check into a hotel, rent an apartment, apply for a job or buy a train ticket. Or you may be detained to undergo re-education, like many thousands of other people.

There are some good comments and suggestions on how you can mitigate this kind of attack on reddit and Hacker News. Also, oh-my-zsh now includes a fix for this issue (which relies on Bracketed Paste Mode support in the terminal). Oh, and it seems that other people wrote a detailed text about this issue in 2008.

SSL/TLS - Typical problems and how to debug them

This guide tries to help with debugging of SSL/TLS problems and shows the most common problems in interaction between client and server. It is not intended to help with writing applications and thus does not care about specific API's etc. But it should help with problems outside of a specific API, like different or broken SSL stacks or misconfigurations.

BearSSL - Constant-Time Mul
As noted in the section on constant-time crypto, integer multiplication opcodes in CPU may or may not execute in constant time; when they do not, implementations that use such operations may exhibit execution time variations that depend on the involved data, thereby potentially leaking secret information.

Why I Still Don't Buy the Russian Hacking Story - Bloomberg View
In the real world outside of soap operas and spy novels, however, any conclusions concerning the hackers' identity, motives and goals need to be based on solid, demonstrable evidence. At this point, it's inadequate. This is particularly unfortunate given that the DNC hacks were among the defining events of the raging propaganda wars of 2016.
