Hacking Internet of Things (IoTs) have become an amazing practice for cyber criminals out there, but messing with <b>Traffic lights</b> would be something more crazy for them.<br />
<br />
The hacking scenes in hollywood movies has just been a source of entertainment for the technology industry, like we've seen traffic lights hacked in Die Hard and The Italian Job, but these movies always inspire hackers to perform similar hacking attacks in day-to-day life.<br />
<br />
Security researchers at the University of Michigan have not only hacked traffic light signals in real life, but also claimed that it’s actually shockingly easy to perform by anyone with a laptop and the right kind of radio. If we compare the traffic light hacks in movies and real life, the reality is much easier.<br />
<div>
<br /></div>
In a <a href="https://jhalderm.com/pub/papers/traffic-woot14.pdf" rel="nofollow" target="_blank"><b>paper</b> </a>study published this month, the security researchers describe how a series of major security vulnerabilities in traffic light systems allowed them to very easily and very quickly seized control of the whole system of at least 100 traffic signals in an unnamed Michigan city from a single point of access.<br />
<br />
Researchers took permission from a local road agency before performing the hack, but they did not disclose exactly where in Michigan they did their research.<br />
<div>
<blockquote class="tr_bq">
‟Our attacks show that an adversary can control traffic infrastructure to cause disruption, degrade safety, or gain an unfair advantage,” the paper explained.</blockquote>
<h3 style="text-align: left;">
SECURITY HOLES IN TRAFFIC LIGHT SYSTEMS</h3>
<div>
The team, led by University of Michigan computer scientist<a href="https://jhalderm.com/" rel="nofollow" target="_blank"><b> J. Alex Halderman</b></a>, said that the networked traffic systems are left vulnerable to three major weaknesses:</div>
<div>
<ol style="text-align: left;">
<li>Unencrypted radio signals,</li>
<li>The use of factory-default usernames and passwords, and</li>
<li>A debugging port that is easy to attack</li>
</ol>
</div>
<div>
This left the network accessible to everyone from cyber criminals to young hackers.</div>
</div>
<div>
<img alt="traffic light hacking" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi-Hz-q_vlDKG-73Dtv8wNchxLXPKflqlSfRg0s32gGEm-8i2hwO9zn4qu74dMYtAKuravqvRHGKdluwbCeSmSEvZvACBAGxGcpRmXaY_Y_iFbbgfhZwihGw771J7JhHBIUJlNj5BKxTzE/s728/traffic-light-hacking.png" /></div>
<div>
<blockquote class="tr_bq">
“The vulnerabilities we discover in the infrastructure are not a fault of any one device or design choice, but rather show a systemic lack of security consciousness,” the researchers report in a paper.</blockquote>
<div>
In an effort to save on installation costs and increase flexibility, the traffic light system makes use of wireless radio signals rather than dedicated physical networking links for its communication infrastructure - this hole was exploited by the researchers. Surprisingly, more than 40 states currently use such systems to keep traffic flowing as efficiently as possible.</div>
<blockquote class="tr_bq">
“The safety critical nature of traffic infrastructure requires that it be secure against computer-based attacks, but this is not always the case,” the team said. “We investigate a networked traffic signal system currently deployed in the United States and discover a number of security flaws that exist due to systemic failures by the designers. We leveraged these flaws to create attacks which gain control of the system, and we successfully demonstrate them on the deployment.”</blockquote>
</div>
<div>
<h3 style="text-align: left;">
WIRELESS SECURITY IN QUESTIONS</h3>
<div>
The Traffic light systems use a combination of 5.8GHz and 900MHz radio signals, depending on the conditions at each intersection, for wireless communication in point-to-point or point-to-multipoint configurations. The 900MHz links use "a proprietary protocol with frequency hopping spread-spectrum (FHSS)," but the 5.8GHz version of the proprietary protocol isn't terribly different from 802.11n.</div>
<div>
<br /></div>
<div>
The researchers says that anyone with a laptop and a wireless card operating on the same frequency as the wirelessly networked traffic light — in this case, 5.8 gigahertz — could access the entire unencrypted network.</div>
<h3 style="text-align: left;">
DEBUG PORT</h3>
<div>
Now, after gaining access, next was to communicate with one of the controllers in their target network. This was done very easily due to the fact that this system’s the control boxes run VxWorks 5.5, a version which by default gets built from source with a debug port left accessible for testing.</div>
<blockquote class="tr_bq">
“By sniffing packets sent between the controller and this program, we discovered that communication to the controller is not encrypted, requires no authentication, and is replayable. Using this information, we were then able to reverse engineer parts of the communication structure,” the paper reads.</blockquote>
<blockquote class="tr_bq">
“Various command packets only differ in the last byte, allowing an attacker to easily determine remaining commands once one has been discovered. We created a program that allows a user to activate any button on the controller and then displays the results to the user. We also created a library of commands which enable scriptable attacks. We tested this code in the field and were able to access the controller remotely.”</blockquote>
<div>
This debug port allowed researchers to successfully turned all lights red or alter the timing of neighboring intersections — for example, to make sure someone hit all green lights on a given route.</div>
<div>
<br /></div>
<div>
More worrying part is the ability of a cyber criminal to perform denial-of-service (DoS) attack on controlled intersections by triggering each intersection’s malfunction management unit by attempting invalid configurations, which would put the lights into a failure mode.</div>
</div>
<h3 style="text-align: left;">
SOLUTION TO PROBLEM</h3>
At last, the team called for manufacturers and operators to improve the security of traffic infrastructure. It recommended that the traffic-system administrators should not use default usernames and passwords, as well as they should stop broadcasting communications unencrypted for “casual observers and curious teenagers” to see.<br />
<blockquote class="tr_bq">
"While traffic control systems may be built to fail into a safe state, we have shown that they are not safe from attacks by a determined adversary," the paper concluded.</blockquote>
Moreover, they also warned that devices like voting machines and even connected cars could suffer similar attacks.<br />

Secure yout account from a new facebook virus !!

<div dir="ltr" style="text-align: left;" trbidi="on">
<b>A new Facebook virus has infected more than 50K users.....are you one of them ??</b><br />
<br />
<div style="text-align: center;">
<img alt="new facebook virus" src="http://4.bp.blogspot.com/-A1WKgGui7rk/U9ZuYfTSYwI/AAAAAAAAAro/e7M4PN3vgPA/s1600/BeFunky_10576968_572202006225590_3130942518715690367_n.jpg.jpg" /></div>
<br />
Facebook viruses have been around for a while, but lately I’ve seen them cropping up even more frequently. You get a Facebook virus when you click on a link that installs malicious code or if you allow an untrusted application access to your account.<br />
<br />
What to do if you too are infected from this virus ?<br />
<br />
The first thing you have to do when you discover you have a Facebook virus is change your Facebook password.<br />
<br />
Finally, check to be sure the application isn’t lurking on your account. It’s probably not, but it’s good to be sure and now is a good time to clean out the apps you’re not using any more anyway. To check the apps connected to your account, follow these instructions:<br />
<br />
1) Go to Account > Privacy Settings.<br />
<br />
2) Click the Edit your Settings link under Apps and Websites.<br />
<br />
<br />
3)Click the top Edit Settings button (by Apps You Use).<br />
The Apps You Use page comes up listing all the apps you’ve allowed to have access to your account.(Mostly the app is named Xperia or HTC)<br />
Go through the list and be sure you know each and every one of the apps.<br />
If you’re unsure if the app is trusted or if you want to remove an app.<br />
<br />
