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.

2020 Melbourne Lord Mayor candidate Wayne Tseng answered some questions about his campaign for the upcoming election from Wikinews. The Lord Mayor election in the Australian city is scheduled to take place this week.

Tseng runs a firm called eTranslate, which helps software developers to make the software available to the users. In the candidate’s questionnaire, Tseng said eTranslate had led to him working with all three tiers of the government. He previously belonged to the Australian Liberal Party, but has left since then, to run for mayorship as an independent candidate.

Tseng is of Chinese descent, having moved to Australia with his parents from Vietnam. Graduated in Brisbane, Tseng received his PhD in Melbourne and has been living in the city, he told Wikinews. Tseng also formed Chinese Precinct Chamber of Commerce, an organisation responsible for many “community bond building initiatives”, the Lord Mayor candidate told Wikinews.

Tseng discussed his plans for leading Melbourne, recovering from COVID-19, and “Democracy 2.0” to ensure concerns of minorities in the city were also heard. Tseng also focused on the importance of the multi-culture aspect and talked about making Melbourne the capital of the aboriginals. Tseng also explained why he thinks Melbourne is poised to be a world city by 2030.

Tseng’s deputy Lord Mayor candidate Gricol Yang is a Commercial Banker and works for ANZ Banking Group.

Currently, Sally Capp is the Lord Mayor of Melbourne, the Victorian capital. Capp was elected as an interim Lord Mayor in mid-2018 after the former Lord Mayor Robert Doyle resigned from his position after sexual assault allegations. Doyle served as the Lord Mayor of Melbourne for almost a decade since 2008.

The Iranian police forces have faced criticism from Ayatollah Hashemi Shahrudi, the head of the judiciary who was appointed by Grand Ayatollah Ali Khamenei, for their re-invigorated campaign to do away with un-Islamic dress.

Ayatollah Shahroudi proclaimed, “Tough measures on social problems will backfire and have counter-productive effects.” Others have, of course, made it clear that un-Islamic dress can lead to moral corruption, engender innumerable vices, and hurt the Islamic character of the nation.

Some believe that no one had any issue with the creation of an Islamic atmosphere. The core of the matter revolves around the implementation of the Islamic dress code; additionally, heavy-handed measures should be shunned. For instance, Mehdi Ahmadi, information head of Tehran’s police, told Al Jazeera: “Some citizens may complain about the way the law is being enforced but they all agree with the plan itself.”

According to one student, “You simply can’t tell people what to wear. They don’t understand that use of force only brings hatred towards them, not love.” Nevertheless, Hojatoll-Islam Mostafa Pour-Mohammadi, Iran’s interior minister who is in charge of policing, prognosticated positive feedback from the populace when he said, “People are unhappy with the social and moral status of the society. They expect that the fight against social insecurity be properly implemented.” Thus, Hujjat al-Islam Pour-Mohammadi re-iterated the necessity of proper implementation and methodology towards the restoration of morality in the Islamic Republic. Islamic officials and religious people affirm that this is indispensable to promote righteousness, curb sin, and bring open sinners to justice.

Following the Islamic Revolution in 1979, hijab became mandatory in Iran for every woman including foreigners after over 98% of citizens voted for an Islamic government. Women may face caning up to 74 strokes for failing to observe hijab. In this recent crackdown, the authorities have arrested many citizens throughout the country. Not only have women been taken into custody for their hair being uncovered on their foreheads and tight clothes that show body shapes, For men they need to cover from knee to their waist as according to Sharia. Even a foreign journalist was detained because the photograph on her press card was indecent.

It has not been clear whence the directive for the re-newed clampdown emanated. Some have blamed Mahmoud Ahmadinejad while Gholam Hossein Elham, the government spokesman, stated to reporters, “The police work as agents of the judiciary to confront crimes. The government as an executive body does not interfere in the affairs of the judiciary.” The following pre-election speech seems to corroborate this latter statement:

The leading supplier of school uniforms in the United Kingdom, Lancashire-based manufacturer Trutex, has announced it is “seriously considering” including GPS tracking devices in future ranges of its uniform products after conducting an online survey of both parents and children.

“As a direct result of the survey, we are now seriously considering incorporating a [tracking] device into future ranges” said Trutex marketing director Clare Rix.

The survey questioned 809 parents and 444 children aged nine to 16. It showed that 44% of parents were worried about the safety of pre-teen children, and 59% wanted tracking devices installed in school apparel. 39% of children aged nine to 12 were prepared to wear clothing with tracking devices in them, while teenagers were notably less enthusiastic and more wary of what Trutex has admitted they see as a “big brother” concept.

However, Trutex has claimed the tracking devices would bring about worthwhile benefits, including being a valuable resource for parents who wanted to keep a close eye on where their children were at all times.

“As well as being a safety net for parents, there could be real benefits for schools who could keep a closer track on the whereabouts of their pupils, potentially reducing truancy levels” says Rix.

Each year, Trutex supplies 1 million blouses, 1.1 million shirts, 250,000 pairs of trousers, 20,000 blazers, 60,000 skirts and 110,000 pieces of knitwear to the UK.

It is not the first company to manufacture school uniforms with a central focus on child safety; last week Essex firm BladeRunner revealed it was selling stab-proof school blazers to parents concerned about violence against their children. The blazers were outfitted with Kevlar, a synthetic fibre used in body armour. It has already received orders internationally, including Australia.

If the Trutex tracking devices go ahead, it is unclear where in the uniform they will be located.

In a Wednesday media event, Apple Inc. released a new lineup of MacBook Air laptops and the 2011 version of the company’s iLife software suite. The “Back to the Mac” event also included a preview of Apple’s forthcoming Mac OS X Lion operating system, to be released in mid-2011.

Apple CEO Steve Jobs unveiled the new products at the Cupertino, California event, saying the company has “been inspired by the work [it has] done on the iPad, and [it wants] to bring it back to the Mac.” Apple has plans to import more features of its iOS mobile operating system to the Mac OS X operating system.

Jobs announced today that the “Lion” release to OS X, which is scheduled for release next summer, will include more support for multitouch and a desktop version of the company’s App Store. He said that the App Store will be available for Apple’s current OS “Snow Leopard” within 90 days, and that applications can be submitted starting next month. Jobs also announced that a beta version of FaceTime, Apple’s IOS video calling application, would be available for OS X users immediately. Several new applications will be added in OS X Lion, dubbed “Mission Control” and “Launchpad.”

In his keynote address Wednesday, Jobs announced the release of Apple’s iLife ’11 software suite, which includes the iPhoto, iMovie, and GarageBand programs. iPhoto has new slide show templates, while iMovie has added audio editing capabilities. GarageBand now includes several new piano- and guitar-playing lessons. iLife ’11 was released on Wednesday as a US$49 upgrade, and is also available free with new Mac purchases.

In another move to bring iOS functionality to Macintosh computers, Jobs announced an updated MacBook Air series of laptops, on sale now. The new MacBook Air uses flash memory rather than a traditional hard drive, and has no CD/DVD drive, an approach seen on the iPad tablet computer. In addition, the laptop’s battery life has been extended, even though it is only 0.68 in (1.73 cm) thick and weighs less than 3 lbs (1.36 kg). “We think it’s the future of notebooks,” said Jobs. There are now two models of the MacBook Air: an 11.6-inch (29.46-cm) version and a 13.3-inch (33.78-cm) model. Analyst Shawn Wu says the company “priced it really aggressively,” referring to the computer’s base price of US$999.

Jobs said that his company sold 13.7 million Macs last year, totaling US$22 billion. In the last financial quarter, Mac sales increased 22 percent, comprising 24 percent of total revenue for Apple. However, the original MacBook Air did not fare so well. Sales and hype over the first Air decreased soon after its introduction, and the line was overshadowed by the release of Apple’s 13-inch (33.02-cm) MacBook Pro. The MacBook Air had not been significantly updated since 2008.

Space Shuttle Atlantis docked with the International Space Station yesterday, and astronauts James Reilly and Danny Olivas were planning their first spacewalk today.

The shuttle docked at 3:36 p.m. EDT (1736 UTC) yesterday, doing an end-over-end flip over South America to let the International Space Station crew photograph the shuttle’s heat shield. Called the “Rotational Pitch Maneuver”, the move is now routine.

In today’s spacewalk, scheduled for 17:53 UTC today, Reilly and Olivas, with the help of a giant robotic arm, will install a new set of solar panels to the station.

After lift-off on Friday from Kennedy Space Center, Atlantis suffered a triangular four-inch by six-inch (10 centimeter by 15 centimeter) tear on a thermal blanket that protects the left side maneuvering rocket pod. Also, small pieces of foam broke off from its external fuel tanks.

Mission chairman John Shannon said he was “leaning toward” ordering another spacewalk so that the tear in the blanket could be repaired.

At least 45 people are reported to have eaten pork which came from a hog farm in Ceres, California in the United States, where pigs from the farm were fed pet food which was recalled because it was contaminated with the chemical melamine.

So far none of the individuals have experienced signs of illnesses, but it is not known what effect the chemical, when ingested, has on humans because no major study has taken place on melamine.

On April 21, at least seven urine samples taken from pigs at hog farm, were tested and the results came back positive for the chemical melamine. At least three samples from the feed used to feed the pigs were tested and those results also came back positive for melamine.

Yesterday, the United States Food and Drug Administration or FDA, said in a statement that “we have no evidence of harm to humans associated with the processed pork product” and that “no recall of meat products processed from these animals is being issued.”

Despite the consumption of pork by humans, the FDA states that the risk to human health is minimal.

“The assessment that, if there were to be harm to human health, it would be very low, is based on a number of factors, including the dilution of the contaminating melamine and melamine-related compounds from the original rice protein concentrate as it moves through the food system. First it is a partial ingredient in the pet food; second, it is only part of the total feed given to the hogs; third, it is not known to accumulate in the hogs and the hogs excrete melamine in their urine; fourth, even if present in pork, pork is only a small part of the average American diet. Neither FDA nor USDA has uncovered any evidence of harm to the swine from the contaminated feed,” added the statement.

On March 19, the manufacturer of the food, Menu Foods, which is based in Mississauga, Ontario in Canada, recalled all of its dog and cat food which totaled over 60 million items. On April 28, Canadian officials announced that they will hold products, such as wheat and corn gluten, as well as soy and rice proteins that have been imported from China until they can be tested for melamine.

It is not known how extensive the outbreak is.
