Startup finds malware intrusions by keeping an eye on processor radio frequencies PFP Cybersecurity, a startup with roots in academia and the military, seeks out malware by analyzing the performance of hardware - not software and not the behavior of devices on the network. PFP’s system compares ongoing radio-frequency output from processors to a baseline that is established when the device is known to be performing legitimate tasks. When it detects anomalies that might represent malicious activity, it triggers alarms. Then it’s up to other tools to figure out what exactly is behind the problem. The system could be used to keep an eye on a large number of similar devices all performing the same task, such as those found in supervisory control and data acquisition (SCADA) networks that support power grids, chemical plants and the like.

Basically, a website performance is not affected by HSTS implementation, and a common user will not notice an obvious difference as if a particular website is using HSTS or not. Consequently, a logical question arises whether there is a possibility to check if the HSTS Policy is indeed enabled. There are a few ways to do that: using command prompt via SSH or with the help of online checkers. Checking HSTS status using Qualys SSL Labs

Understanding the Risk of Mixed Content Warnings Ever see one of these? Or these? Or maybe this one? It means something is wrong with the website – very wrong – yet somehow we seem to keep building websites that do this. Photos of an NSA “upgrade” factory show Cisco router getting implant A document included in the trove of National Security Agency files released with Glenn Greenwald’s book No Place to Hide details how the agency’s Tailored Access Operations (TAO) unit and other NSA employees intercept servers, routers, and other network gear being shipped to organizations targeted for surveillance and install covert implant firmware onto them before they’re delivered. These Trojan horse systems were described by an NSA manager as being “some of the most productive operations in TAO because they pre-position access points into hard target networks around the world.” The document, a June 2010 internal newsletter article by the chief of the NSA’s Access and Target Development department (S3261) includes photos (above) of NSA employees opening the shipping box for a Cisco router and installing beacon firmware with a “load station” designed specifically for the task.

HTTP Strict Transport Security HTTP Strict Transport Security (HSTS) is a simple and widely supported standard to protect visitors by ensuring that their browsers always connect to a website over HTTPS. HSTS exists to remove the need for the common, insecure practice of redirecting users from to URLs. When a browser knows that a domain has enabled HSTS, it does two things: Always uses an connection, even when clicking on an link or after typing a domain into the location bar without specifying a protocol.Removes the ability for users to click through warnings about invalid certificates. A domain instructs browsers that it has enabled HSTS by returning an HTTP header over an HTTPS connection.

Secure Salted Password Hashing - How to do it Properly If you're a web developer, you've probably had to make a user account system. The most important aspect of a user account system is how user passwords are protected. User account databases are hacked frequently, so you absolutely must do something to protect your users' passwords if your website is ever breached. The best way to protect passwords is to employ salted password hashing. This page will explain why it's done the way it is. There are a lot of conflicting ideas and misconceptions on how to do password hashing properly, probably due to the abundance of misinformation on the web.

Exploit writing tutorial part 10 : Chaining DEP with ROP – the Rubik’s[TM] Cube Table of Contents Introduction About 3 months after finishing my previous exploit writing related tutorial, I finally found some time and fresh energy to start writing a new article.

HTTP Strict Transport Security Cheat Sheet Last revision (mm/dd/yy): 08/10/2016 Description HTTP Strict Transport Security (HSTS) is an opt-in security enhancement that is specified by a web application through the use of a special response header. Once a supported browser receives this header that browser will prevent any communications from being sent over HTTP to the specified domain and will instead send all communications over HTTPS. It also prevents HTTPS click through prompts on browsers. The specification has been released and published end of 2012 as RFC 6797 (HTTP Strict Transport Security (HSTS)) by the IETF.

Inviting Hackers into Your Automated Home I was at the Web Directions South conference the other day and you know what really struck me? There is a lot of very cool, very connected stuff either here now or coming very soon. Hackable stuff! So there’s this term going around which is The Internet of Things (it has its own Wikipedia page so it must be real), or in human speak, stuff that’s connected to the web. Unusual stuff like domestic appliances and cars – literally “things” rather than devices as we know them such as PCs and phones. The term isn’t new, but the rapid emergence of “things” is.
