Bluesnarfing Bluesnarfing is the unauthorized access of information from a wireless device through a Bluetooth connection, often between phones, desktops, laptops, and PDAs (personal digital assistant.). This allows access to a calendar, contact list, emails and text messages, and on some phones, users can copy pictures and private videos. Both Bluesnarfing and Bluejacking exploit others' Bluetooth connections without their knowledge. While Bluejacking is essentially harmless as it only transmits data to the target device, Bluesnarfing is the theft of information from the target device. Current mobile software generally must allow a connection using a temporary state initiated by the user in order to be 'paired' with another device to copy content. Any device with its Bluetooth connection turned on and set to "discoverable" (able to be found by other Bluetooth devices in range) may be susceptible to Bluejacking and possibly to Bluesnarfing if there is a vulnerability in the vendor's software.
SSD drives difficult to wipe securely, researchers find Current methods for securely wiping data from magnetic hard disks simply aren't reliable enough to use on solid state drives (SSDs), a detailed study by engineers at the University of California has found. The techies at the university’s Department of Computer Science and Engineering uncovered a range of problems in secure SSD ‘sanitisation’ of both whole drives and individual files, starting with problems in the way some drive firmware implemented the ATA/SCSI commands to conduct the erase function. The researchers tested twelve unnamed SSD drives, and found that only four of them successfully erased the test whole-drive fingerprint image. Three drives failed, two because of bugs in the firmware, and one reported success despite the fact that all data on it remained intact and accessible. The results for wiping a single file from an SSD using a range of common sanitisation protocols were even worse, with between 4 percent and 75 percent of the data recoverable.
What Is a Packet Sniffer? (with pictures) A packet sniffer is a device or program that allows the user to eavesdrop on traffic traveling between networked computers. The program will capture data that is addressed to other machines, saving it for later analysis. All information that travels across a network is sent in "packets." For example, when an email is sent from one computer to another, it is first broken up into smaller segments. In the example of the simplest network where computers share an Ethernet wire, all packets that travel between the computers are "seen" by every computer on the network. A slightly safer environment is a switched Ethernet network. There are ways to hack the switch protocol, however. These programs can also be used on the Internet to capture data traveling between computers. A packet sniffer is not just a hacker's tool. The best defense against eavesdropping is a good offense: encryption.
Playstation hacker raises money to fight Sony lawsuit A hacker sued by Sony for jailbreaking its PlayStation 3 game claims that he's raised enough money to begin his defence efforts just two days after launching an online appeal for donations. In a blog post, George Hotz, 21, thanked supporters and announced that the first round of donations to his cause has been closed. "I have enough to cover my legal fees for the time being," Hotz wrote. In an interview, Hotz' attorney Stewart Kellar confirmed that the fundraising effort has been closed. Kellar said that he has filed a motion asking the San Francisco federal court to dismiss the case because Hotz is a New Jersey native and therefore not under the jurisdiction of the California court in this case. Hotz who is already known for jailbreaking the iPhone, is one of three named individuals in a lawsuit filed by Sony Computer Entertainment Inc. in federal court in San Francisco. The lawsuit has drawn considerable criticism in some quarters. The site also attracted critics.
Hacking for Beginners One of the best things about computers is how dynamic they are. There is so much information about computers and it changes constantly. As a hacker, you are at the leading edge of changes to technology. This makes it a very exciting and interesting field of study and can even lead to some awesome job opportunities as a computer security expert. Hackers are often misrepresented as “evildoers” bent on stealing money and personal information from individuals and businesses. White Hat Hackers are benevolent security experts that do not seek profits from illegal network access. Black Hack Hackers are the people who use their knowledge of computers for illegal or unethical purposes. The point – use your computer knowledge to promote learning and security; not to be a thief or criminal. By “thinking outside the box,” hackers are able to solve problems and accomplish mundane tasks more efficiently by leveraging their knowledge of computer systems. Programming Network Hacking
Hackers avoiding encryption with memory scraping What's "pervasive memory scraping" and why is it considered by SANS Institute security researchers to be among the most dangerous attack techniques likely to be used in coming the coming year? Simply put, pervasive memory scraping is used by attackers who have gained administrative privileges to successfully get hold of personally identifiable information (PII) and other sensitive data held encrypted in a file system, according to Ed Skoudis, senior security consultant at InGuardians who is also an instructor at SANS events. Evidence of this attack is coming up again and again in data breach cases, he said. "Data is encrypted in a file system where it's stored," said Skoudis, who joined with Johannes Ullrich, chief research officer at SANS Technology Institute, to speak at the RSA Conference last week on dangerous attack techniques that appear to be on the rise. One interesting aspect about this attack is that "the bad guys want to maintain the end-to-end encryption, too."
Hyper-V Hyper-V, codenamed Viridian[1] and formerly known as Windows Server Virtualization, is a native hypervisor; it can create virtual machines on x86-64 systems.[2] Starting with Windows 8, Hyper-V supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V was first released along Windows Server 2008 and became a staple of the Windows Server family ever since. History[edit] A beta version of Hyper-V was shipped with certain x86-64 editions of Windows Server 2008. Microsoft provides Hyper-V through two channels: Part of Windows: Hyper-V is an optional component of Windows Server 2008 and later. Hyper-V Server[edit] Hyper-V Server 2008 was released on October 1, 2008. Hyper-V Server 2008 R2 (an edition of Windows Server 2008 R2) was made available in September 2009 and includes Windows PowerShell v2 for greater CLI control.
Authentication Case Studies Below are examples of how holograms are working in different industries to provide protection against counterfeiting, protect consumers from the harmful effects of fakes, enable effective identification of people and goods and ensure that the integrity and value of critical documents and intellectual property are maintained. Banknotes Holograms were first used on currency in the late 1980s. Today they are used in or on banknotes issued by more than half of the world's central banks and issuing authorities. This article (published by Currency News in 2003 - soon to be updated) looks at the development of holograms in this highly important and economically-critical sector. Payment Cards The first use of secure holograms was on Mastercard and then Visa in the early 1980s. Tax Stamps Also known as duty/fiscal stamps or banderoles, these represent the second largest market by volume for holograms (after banknotes). Sporting Events IT Consumables

It's a great primer for students and a nice refresher for others. IP subnetting is a fundamental subject that's critical for any IP network engineer to understand, yet students have traditionally had a difficult time grasping it. IP addresses and subnets Although IP stands for Internet Protocol, it's a communications protocol used from the smallest private network to the massive global Internet. ...increment 252 hosts... ...increment 4+ billion hosts... The word subnet is short for sub network--a smaller network within a larger one. Subnets have a beginning and an ending, and the beginning number is always even and the ending number is always odd. The graphical subnet ruler Over the years, as I watched people struggle with the subject of IP subnetting, I wanted a better way to teach the subject. Note that for every bit increase, the size of the subnet doubles in length, along with the number of hosts. IP classes made simple
