FBI says it may have found a way to unlock shooter’s iPhone

The FBI says it may have discovered a way to break into the iPhone used by one of the San Bernardino mass shooters, and an important court hearing in the case that was scheduled for Tuesday has been postponed. "On Sunday, March 20, 2016, an outside party demonstrated to the FBI a possible method for unlocking Farook’s iPhone," lawyers for the government said in a court filing Monday afternoon, referring to the shooter Syed Farook. "Testing is required to determine whether it is a viable method that will not compromise data on Farook’s iPhone. If the method is viable, it should eliminate the need for the assistance from Apple set forth in the All Writs Act Order in this case," the government lawyers wrote.To read this article in full or to leave a comment, please click here

Tor Project says it can quickly catch spying code

The Tor Project is fortifying its software so that it can quickly detect if its network is tampered with for surveillance purposes, a top developer for the volunteer project wrote on Monday.There are worries that Tor could either be technically subverted or subject to court orders, which could force the project to turn over critical information that would undermine its security, similar to the standoff between Apple and the U.S. Department of Justice.Tor developers are now designing the system in such a way that many people can verify if code has been changed and "eliminate single points of failure," wrote Mike Perry, lead developer of the Tor Browser, on Monday.To read this article in full or to leave a comment, please click here

Cisco reorganizes engineering in a big way; veteran Ahuja out

Label Switched Multicast — Configuration

In the previous post (Label Switched Multicast - An Introduction) in this series on Label Switched Multicast (LSM) I introduced the concepts behind LSM and draft-rosen, the two most poplar methods for transporting multicast traffic through MPLS Layer 3 VPNs.

In this article I will talk through the configuration of LSM on the PE and P routers and get to the point where two CEs are successfully passing multicast traffic via the MPLS network. All of the configuration examples will be relevant to Cisco IOS.

As was the case in the introduction article in the series, it's best if you already have a good understanding of multicast and MPLS before reading this article.

At the end of this article you'll be able to start configuring your own LSM environment using the configuration samples here as a template.

Hyper-connected cars can drive you to paranoia

This sounds like an ugly thing for a ham radio operator and director of a community radio station to say but: Clip your car’s antenna. Or stuff a wad of chewing gum into your car’s USB port, and perhaps its ODB2 port. Enough is enough.As Andy Greenberg of WIRED wrote of a US DOT Public Service Announcement, “it is important that consumers and manufacturers maintain awareness of potential cyber security threats” to their now hyper-connected cars.There are likely two antennas, one for radio and one that connects your car to a third-party monitoring system. On-Star, if you have it, is tracking your every move. Do they give information to the NSA? Consider that the NSA probably already gets such cell-phone transmitted information anyway. GM cards have it, and many other cars have their own in-vehicle two-way monitoring systems.To read this article in full or to leave a comment, please click here

Tim Cook: Apple won’t shrink in fight for data privacy

Apple won't shrink from its responsibility to safeguard the privacy of its users, CEO Tim Cook said Monday, a day before Apple lawyers are due to face off with the Department of Justice in a California courtroom.Cook's comments confirm the company's continued defiance against a request from the FBI to develop software that will allow it to make multiple guesses of an iPhone passcode without triggering the phone's self-destruct feature."I've been humbled and deeply grateful for the outpouring of support that we've received from Americans across the country from all walks of life," said Cook at an event in Cupertino held to announce new products.

Leaked Clinton email shows Google wanted to help overthrow Syrian President

Last week WikiLeaks launched the Hillary Clinton email archive; it’s described as “a searchable archive for 30,322 emails & email attachments sent to and from Hillary Clinton's private email server while she was Secretary of State. The 50,547 pages of documents span from 30 June 2010 to 12 August 2014. 7,570 of the documents were sent by Hillary Clinton.”The Washington Examiner honed in on an email from 2012 that was forwarded to Clinton after her deputy chief of staff noted that it was a “pretty good idea.” It is supposedly proof that Google wanted to help insurgents overthrow Syrian President Bashar Assad. It seems like the State Department, Google and Al Jazeera were all in cahoots.To read this article in full or to leave a comment, please click here

The Design Mindset (2)

In a comment from last week’s post on the design mindset, which focuses on asking what through observation, Alan asked why I don’t focus on business drivers, or intent, first. This is a great question. Let me give you three answers before we actually move on to asking why?

Why can yuor barin raed tihs? Because your mind has a natural ability to recognize patterns and “unscramble” them. In reality, what you’re doing is seeing something that looks similar to what you’ve seen before, inferring that’s what is meant now, and putting the two together in a way you can understand. It’s pattern recognition at it’s finest—you’re already a master at this, even if you think you’re not. This is an important skill for assessing the world and reacting in (near) real time; if we didn’t have this skill, we wouldn’t be able to tolerate the information inflow we actually receive on a daily basis.network-design-mindset-01

The danger is, of course, that you’re going to see a pattern you think you recognize and skip to the next thing to look at without realizing that you’ve mismatched the pattern. These pattern mismatches can be dangerous in the real world—like the time I Continue reading

The need If you work with Linux machines and you don’t use a terminal multiplexer you’re doing it wrong. What is a terminal multiplexer? It lets you switch easily between several programs in one terminal, detach them (they keep running in the background) and reattach them to a different terminal. The Solution I use tmux, […]
