On Monday, digital security researchers Mathy Vanhoef and Frank Piessens of Belgium’s KU Leuven university publicly disclosed a security vulnerability in the WPA2 Wi-Fi (wireless local-area networking) protocol, which they called KRACK (for Key Reinstallation Attack). Their study claimed KRACK affects every modern device using Wi-Fi; it can be fixed by a software update, researchers said.

Vanhoef wrote, “Attackers can use this novel attack technique to read information that was previously assumed to be safely encrypted. This can be abused to steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos and so on.” Vanhoef notified vendors about the flaw in July, including UNIX-like operating system OpenBSD. “If your device supports Wi-Fi, it is most likely affected. […] In general, any data or information that the victim transmits can be decrypted”, he wrote.

The study papers, which were submitted for review on May 19, were kept in confidence allowing companies to fix the security flaw. The United States-based Computer Emergency Response Team (CERT) informed vendors on August 28. The Wi-Fi Alliance said it “could be resolved through a straightforward software update.” OpenBSD released their software patch on August 30.

Exploring the flaw which affected every device the researchers had tested, National Cyber Security Centre of the UK said “the attacker would have to be physically close to the target”. But due to this flaw, an attacker can send malware or ransomware on the websites, Vanhoef claimed.

Linux-based operating systems including Android v6.0 and higher are especially affected by this flaw, while Windows and iOS are not as vulnerable as Android by this flaw as they do not fully implement WPA2.

Microsoft reportedly has released security patches for Windows 7, 8, 8.1 and 10. Google said Android operating systems would receive the updates in the software update scheduled to be made available on November 6. Apple has implemented the patch in the beta versions of their operating system iOS, macOS, tvOS and watchOS, however it is yet to roll out patches for stable operating systems.

WPA2 protocol has been used for more than a decade, and has been compulsory for Wi-Fi since 2006. KRACK would also affect various home appliances which can be controlled over Wi-Fi, within the so-called “Internet of things”. Andrew Martin from Oxford University said, “We can be sure a lot of these devices won’t be patched[…] Whether that matters for this attack or only for some future attack is yet to be seen.”

The study and its findings are scheduled for presentation at the ACM (Association for Computing Machinery) Computer and Communications Security conference on November 1.

The new version of Apple Inc.’s tablet computing device, the iPad 2, has gone on sale in the United States at Apple Stores and a number of other retailers (including Wal-Mart, Target, Sam’s Club, Best Buy, Verizon, and AT&T), a shift from last year’s launch which was only available through Apple’s stores. The product will go on sale internationally on March 25.

The device was announced on March 2 at an event at the Yerba Buena Center for the Arts in San Francisco, California. CEO Steve Jobs emerged from sick leave to make the announcement.

The iPad 2 has an all-new design and has several improvements over the original iPad. The device runs on a dual-core Apple A5 CPU. According to Jobs, the CPU’s new dual-core capability enhances multitasking and doubles the processing speed. Apple additionally introduced a magnetic ‘Smart Cover’ accessory that snaps to the front screen of the device along with several new apps ported from the Mac OS X operating system and the iPhone. These include iMovie, GarageBand, and Photo Booth. The new iPad introduces front and rear cameras which enable FaceTime and video. The new tablet is fifteen percent lighter and 33 percent thinner than the previous version—thinner than an iPhone 4—and has beveled edges. It is available in black and white and continues to be capable of ten hours of battery life on a single charge.

The announcement came after months of rumors about the successor to the original iPad. Competitors have designed tablets to compete with the iPad, such as Motorola’s Xoom powered by the Android operating system. Apple, who normally follows a yearly product cycle, has pressed its iPad successor into the marketplace almost a full month earlier than usual.

Tablet computers have existed for years but, until recently, have not been popular amongst consumers. Tablet sales totaled 90,000 in 2009. Apple sold nearly fifteen million iPads worldwide in 2010, generating US$2 billion in revenue within three months. In 2010, Apple held a 75% share of the tablet computer market. According to one analyst, even with competition, iPads will still make up at least 20 million of the more than 24 million tablet computers sold in the United States in 2011. An analyst predicted ‘conservatively’ that 35 million iPad 2s will be sold in 2011. One analyst credits Apple’s enormous App Store for the iPad’s continued domination. Apple also holds an advantage in price over other tablets, many of which are still first generation devices. An analyst at J.P. Morgan predicts an overabundance of tablets caused by faltering demand. This could have drastic effects on competitors.

The iPad connects to the Internet over Wi-Fi and 3G models of the new device can connect to the wireless networks of AT&T or Verizon Wireless. The iPad 2 will start at US$499—the same starting price of the original iPad. The equivalent model of the original iPad has been reduced to US$399.

On Tuesday, the Euro fell to a new record low in relation to the Swiss Franc, and to multi-month lows against the U.S. Dollar and Japanese yen; all considered by investors to be safe currencies during times of economic turmoil.

The Wall Street Journal reported earlier that recent comments from the newly installed head of the International Monetary Fund, France’s Christine Lagarde, resulted in a sell-off of the Euro. At a roundtable discussion in Washington, Lagarde noted that the IMF had not yet reached discussion of terms and conditions of a second Greek bailout plan. In fact, a representative from the IMF is currently meeting with Eurozone policymakers to draft such a new proposal. The yield differential between Italian bonds and German bonds has spread to more than 300 basis points, something not seen in over a decade and evidence of investors’ concern.

Adding to the Euro’s woes is the upcoming release of the bank stress tests on Friday. The European Bankers Association said that they expect the data release to shed new light on the Eurozone’s banking situation. Representatives of several of the Eurozone’s governments, including Germany, have requested that the association consider releasing fewer specific details for fear that investor panic will ensue. The inadequacy of the capitalization rates has been an issue with the European Central Bank, whose president recently called upon Eurozone banks to make every effort to put their balance sheets in order.

For the time being at least, an unsubstantiated rumor reported by the Wall Street Journal states that the Eurozone’s central banks’ purchase of periphery debt has helped to quell the downward momentum of the Euro.

Australian swimmer Ian Thorpe is reported to be feeling much better after suffering from chest pain for some time.

The Olympic gold medalist was due to swim in the 100m and 200m freestyle and in three relays at the Commonwealth Games, but due to his complaints his fitness has been in doubt. He has been unable to take the drugs needed to overcome his pain as they are banned from the Games.

Thorpe told the media Thursday “It’s actually the best I’ve felt in a while; the antibiotics are starting to work.”
