Hackers “are learning that it’s not so easy to write secure code,” Toro says. “Most of us in the business of securing our applications and systems know that bulletproofing software is an extremely expensive and exhaustive undertaking. Malware creators who have to look to their own defences would have to slow down the production of new attacks.”
FYI, if you want to know what it looks like when you hack a hacker, look no further than the seminal 1995 film Hackers.
In IE10 and other new browsers one may create MessageChannel objects that have two MessagePorts each connected (w3c spec calls it entangled) to one another such that postMessage on one port results in the message event firing on the other. You can pass an array of ports as the last parameter to postMessage and they show up in the ports property of the message event arg.
The postMessage here is like the worker postMessage and unlike the window and iframe postMessage in that it applies no origin checking:
Unfortunately the origin isn't an optional parameter at the end to make the two postMessages have the same signature.
On the event handler side, the event arg always has an origin property. But in the no origin case it is always the empty string.
There is also a source property on the message event arg which if set is an object that has a postMessage property allowing you to post back to your caller. It is set for the origin case, however, in the no origin case this property is null. This is somewhat reasonable because in the case of MessagePort and Workers there are only two endpoints so you always know the source of a message implicitly. Unlike the origin case in which any iframe or window can be calling postMessage on any other iframe or window and the caller is unknown. So not unreasonable but it would be nice if the source property was always set for consistency.
When a MessageChannel is created it has two MessagePorts, but until those ports are started they will queue up any messages they receive. Once started they will dispatch all queued messages. Ports don't have to be started to send messages.
A port may be started in two ways, either by explicitly calling the start method on the port, or by setting the onmessage callback property on the port. However, adding an event listener via addEventListener("message", does not start the port. It works this way in IE and Chrome and the spec states this as well.
The justification is that since you can have only one callback via onmessage that once set you must implicitly be ready to receive messages and its fine to start the port. As opposed to the addEventListener in which case the user agent cannot start implicitly because it doesn't know how many event listeners will be added. I found Hixie stating this justification in geoloc meeting notes.
The first independent film to gross more than $200 million, Pulp Fiction was a shot of adrenaline to Hollywood’s heart, reviving John Travolta’s career, making stars of Samuel L. Jackson and Uma Thurman, and turning Bob and Harvey Weinstein into giants. How did Quentin Tarantino, a high-school dropout and former video-store clerk, change the face of modern cinema? Mark Seal takes the director, his producers, and his cast back in time, to 1993.
Not The Onion subreddit is for real stories that sound like The Onion articles. This is a compilation of those stories into a page that looks like The Onion.
This sounds like an Onion article but is actually a real article on NOAA’s website describing why we can’t use nukes to destroy tropical storms. This in the frequently asked questions.
According to the links within this article, although the root URI of the router requires authentication, the /password.cgi URI doesn’t and the resulting returned HTML contains (but does not display) the plaintext of the password, as well as an HTML FORM to modify the password that is exploitable by CSRF.
The attack… infected more than 4.5 million DSL modems… The CSRF (cross-site request forgery) vulnerability allowed attackers to use a simple script to steal passwords required to remotely log in to and control the devices. The attackers then configured the modems to use malicious domain name system servers that caused users trying to visit popular websites to instead connect to booby-trapped imposter sites.
Winterton, a senior entomologist at the California Department of Food and Agriculture, has seen a lot of bugs. But he hadn’t seen this species before.
There’s no off switch when you’re the senior entomologist. If you’re browsing the web you find your way to Flickr photos of insects or start correcting Wikipedia articles on insects.
One persons quest to watch the Olympics online.
The location requirements (guessed at via IP address) are irritating. The requirement that you have a particular cable subscription to view video online seems like not network neutrality.

Sticking to an exercise routine takes dedication, and many fitness junkies swear that a running companion can be a huge help. That’s why researchers have developed “Joggobot,” a quad-rotor helicopter drone designed to motivate joggers by flying in front of them.
The aerial robot uses its camera to spot a colorful pattern on a T-shirt worn by the jogger, and flies at a safe distance ahead. The runner can control Joggobot using a smartphone: In “companion mode,” the drone simply maintains the jogger’s pace; in “coach mode,” it pushes its human trainee a little faster.
Don’t worry, there’s a video
Maybe it should chase you instead?
