Inconsistent, misleading password meters can increase risk of cyber attacks: Study

Washington D.C., Dec 23: Inconsistent and misleading advice offered on some of the world's most popular websites could actually be doing more harm than good, says a recent study.

Password meters">Password meters are frequently made available to help the users secure their personal data against the threats posed by cybercriminals.

The study conducted at the University of Plymouth has assessed the effectiveness of 16 password meters that people are likely to use or encounter on a regular basis.

The research says that there is a clear level of variation in the advice offered across different websites.

The study was published in the journal Computer Fraud and Security.

The main focus was dedicated password meter websites, but the study also sought to assess those embedded in some common online services (including Dropbox and Reddit) and those found as standard on some of our devices.

And while some meters do effectively steer users towards more secure account passwords, some will not pick them up when they try to use 'abc123', 'qwertyuiop' and 'iloveyou' - all listed this week among the worst passwords of 2019.

The study was conducted by Steve Furnell, Professor of Information Security and Leader of the University's Centre for Security, Communications and Network Research.

Commenting on the latest research, Prof Furnell said: "Over the festive period, hundreds of millions of people will receive technology presents or use their devices to purchase them."

"The very least they should expect is that their data will be secure and, in the absence of a replacement for passwords, providing them with consistent and informed guidance is key in the quest for better security."

"What this study shows is that some of the available meters will flag an attempted password as being a potential risk whereas others will deem it acceptable. Security awareness and education are hard enough, without wasting the opportunity by offering misleading information that leaves users misguided and with a false sense of security."

The study tested 16 passwords against the various meters, with 10 of them being ranked among the world's most commonly used passwords (including 'password' and '123456').

Of the 10 explicitly weak passwords, only five of them were consistently scored as such by all the password meters, while 'Password1!' performed far better than it should do and was even rated strongly by three of the meters.

However, one positive finding was that a browser-generated password was consistently rated strong, meaning users can seemingly trust these features to do a good job.

Prof Furnell added: "Password meters">Password meters themselves are not a bad idea, but you clearly need to be using or providing the right one."

"It is also worth remembering that, regardless of how the meters handled them, many systems and sites would still accept the weak passwords in practice and without having offered users any advice or feedback on how to make better choices," he added.

Leiden, Jul 2: Astronomers have discovered a luminous galaxy caught in the act of reionizing its surrounding gas only 800 million years after the Big Bang.

The research, led by Romain Meyer, PhD student at UCL in London, UK, has been presented at the virtual annual meeting of the European Astronomical Society (EAS).

Studying the first galaxies that formed 13 billion years ago is essential to understanding our cosmic origins. One of the current hot topics in extragalactic astronomy is 'cosmic reionization,' the process in which the intergalactic gas was ionized (atoms stripped of their electrons).

Cosmic reionization is similar to an unsolved murder: We have clear evidence for it, but who did it, how and when? We now have strong evidence that hydrogen reionization was completed about 13 billion years ago, in the first billion years of the universe, with bubbles of ionized gas slowly growing and overlapping.

The objects capable of creating such ionized hydrogen bubbles have however remained mysterious until now: the discovery of a luminous galaxy in which 60-100 percent of ionizing photons escape, is likely responsible for ionizing its local bubble. This suggests the case is closer to being solved.

The two main suspects for cosmic reionization are usually 1) a population of numerous faint galaxies leaking ~10 percent of their energetic photons, and 2) an 'oligarchy' of luminous galaxies with a much larger percentage (>50 percent) of photons escaping each galaxy.

In either case, these first galaxies were very different from those today: galaxies in the local universe are very inefficient leakers, with only <2-3 percent of ionizing photons escaping their host. To understand which galaxies governed cosmic reionization, astronomers must measure the so-called escape fractions of galaxies in the reionization era.

The detection of light from excited hydrogen atoms (the so-called Lyman-alpha line) can be used to infer the fraction of escaping photons. On the one hand, such detections are rare because reionization-era galaxies are surrounded by neutral gas which absorbs that signature hydrogen emission.

On the other hand, if this hydrogen signal is detected it represents a 'smoking gun' for a large ionized bubble, meaning we have caught a galaxy reionizing its surroundings. The size of the bubble and the galaxy's luminosity determines whether it is solely responsible for creating this ionized bubble or if unseen accomplices are necessary.

The discovery of a luminous galaxy 800 million years after the Big Bang supports the scenario where an 'oligarchy' of bright leakers emits most of the ionizing photons.

"It is the first time we can point to an object responsible for creating an ionized bubble, without the need for a contribution from unseen galaxies.

Additional observations with the upcoming James Webb Space Telescope will enable us to study further what is likely one of the best suspects for the unsolved case of cosmic reionization," said Meyer.

New Delhi, Jul 13: The Telecom Regulatory Authority of India (TRAI) has blocked Bharti Airtel's Platinum and Vodafone Idea's RedX premium plans that offer faster data speeds and priority services to customers as both the plans were violating net neutrality norms.

The telecom watchdog has asked Bharti Airtel to explain within seven days how such a similar plan being launched does not violate the rules of net neutrality.

Vodafone Idea's RedX plan has been in the market since November 2019. They made some modifications in May 2020 and the Bharti Airtel was soon going to launch a similar plan.

According to TRAI, the higher speed for premium customers discriminate against others and violates net neutrality.

Responding to TRAI's move, Airtel spokesperson said: "We are passionate about delivering the best network and service experience to all our customers. This is why we have a relentless obsession to eliminate faults and have been consistently recognised by international agencies as the best network in terms of speed, latency and video experience."

"At the same time, we want to keep raising the bar for our post-paid customers in terms of service and responsiveness. This is an ongoing effort at our end," the spokesperson said.

San Francisco, Mar 18: Facebook said a bug in its anti-spam system temporarily blocked the publication of links to news stories about the coronavirus. Guy Rosen, Facebook's vice president of integrity, said on Twitter Tuesday that the company was working on a fix for the problem.

Users complained that links to news stories about school closings and other information related to the virus outbreak were blocked by the company's automated system.

Later on Tuesday, Rosen tweeted that Facebook had restored all the incorrectly deleted posts, which also covered topics beyond the coronavirus.

Rosen said the problems were unrelated to any changes in Facebook's content-moderator workforce. The company reportedly sent its human moderators home this week because of the coronavirus outbreak.

A representative for Facebook did not immediately respond to questions on the status of Facebook's content moderators, many of whom do not work directly for the company and are not always able to work from home.
