While using your cell phone at a massive public event, like a concert, conference, or sporting event, you have probably experienced slow communication, poor performance or slow browsing speeds, as crowds arrive. That's because of ‘ Spectrum Crunch ’, which means, Interference of WiFi signals with each other. WiFi signals of all cell-phones in a large event interfere with each other because they are all fighting over the same limited spectrum but there is not enough bandwidth to handle all the traffic from the cellphones that are trying to use the same frequency slice at the same time, leaving them frustrated with painfully slow Internet access. However, a team of researchers from the MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) has developed a solution for this problem. In a new research paper, 'Real-time Distributed MIMO Systems,' published online this week, the MIT team described a system for managing networks that cause the WiFi ...

Recently released NSA exploit from " The Shadow Brokers " leak that affects older versions of Cisco System firewalls can work against newer models as well. Dubbed ExtraBacon , the exploit was restricted to versions 8.4.(4) and earlier versions of Cisco's Adaptive Security Appliance (ASA) – a line of firewalls designed to protect corporate, government networks and data centers. However, the exploit has now been expanded to 9.2.(4) after researchers from Hungary-based security consultancy SilentSignal were able to modify the code of ExtraBacon to make it work on a much newer version of Cisco's ASA software. Both Cisco and Fortinet have confirmed their firewalls are affected by exploits listed in the Shadow Brokers cache that contained a set of " cyber weapons " stolen from the Equation Group . The Equation Group is an elite hacking group tied to the NSA's offensive Tailored Access Operations (TAO) and linked to the previous infamous Regin and S...

A winning anonymous bidder bought 2,700 Bitcoins ( worth roughly $1.6 Million ) in an auction held by the United States Marshals Service ( USMS ) on Monday. The US government announced at the beginning of this month its plans to auction 2,719 Bitcoins that were seized during several criminal, civil and administrative cases like Silk Road. The US Marshals confirmed to CoinDesk that four bids were received in the auction that took place between 13:00 and 19:00 UTC on August 22. The majority of the Bitcoins in the auction were stemmed from investigations of the Silk Road online black marketplace. Included 2,719 Bitcoins in the auction were: Around 1,300 Bitcoins seized from a civil case related to Matthew Gillum, a Silk Road drug dealer, who was sentenced to nine years in prison in 2015. Only 2.8 Bitcoins directly came from Silk Road founder Ross Ulbricht , who was found guilty of operating Silk Road for illegal goods and handed two life sentences . Some 65 Bitcoins came ...

If you are a fan of Unreal Tournament from Epic Games or ever have participated in discussions on the online forums run by Epic Games, you possibly need to change your forum password as soon as possible. It seems the Unreal Engine and its creators, Epic Games' forums have recently been compromised by an unknown hacker or a group of hackers, who have stolen more than 800,000 forum accounts with over half a Million from the Unreal Engine's forums alone. The hackers get their hands on the forum accounts by exploiting a known vulnerability resided in an outdated version of the vBulletin forum software, which allowed them to get access to the full database. Epic believes registration information that includes usernames, scrambled passwords, email addresses, dates of birth, IP addresses, and date of joining, may have been obtained in the attack. "We believe a recent Unreal Engine and Unreal Tournament forum compromise revealed email addresses and other data entered in...

If your webcam has stopped working after installing recently-released Microsoft's big Anniversary Update for Windows 10 , you are not alone. With some significant changes to improve Windows experience, Windows 10 Anniversary Update includes the support for webcams that has rendered a number of different webcams inoperable, causing serious issues for not only consumers but also the enterprise. The problem is that Microsoft added some new ways for applications to access webcams with Microsoft's new Windows Camera Frame Server, preventing webcams from using two particular compression formats—H.264 and MJPEG. Microsoft decided that the Camera Frame Server should only receive an uncompressed YUY2 encoding stream from the webcam, which is affecting far more devices than Microsoft expected, causing Millions of cameras to crash. This is the reason why your camera hangs, freezes, or simply not works when you try to do a video calling with your friend over Skype. Brad Sams of ...

Last week, a group calling itself " The Shadow Brokers " published what it said was a set of NSA "cyber weapons," including some working exploits for the Internet's most crucial network infrastructure, apparently stolen from the agency's Equation Group in 2013. Well, talking about the authenticity of those exploits, The Intercept published Friday a new set of documents from the Edward Snowden archive, which confirms that the files leaked by the Shadow Brokers contain authentic NSA software and hacking tools used to secretly infect computers worldwide. As I previously mentioned , the leaked documents revealed how the NSA was systematically spying on customers of big technology companies like Cisco, Fortinet, and Juniper for at least a decade. Hacking tools from The Shadow Brokers leak named ExtraBacon, EpicBanana, and JetPlow, contain exploits that can compromise Cisco firewall products including devices from the Adaptive Security Appliance (ASA) li...
