WhatsApp fixes dangerous flaw in Web app

whatsapp flawWhatsApp, the widely used messaging program, has fixed a dangerous flaw in its Web app that could be used to trick people into installing malware, according to Check Point.

The flaw could affect as many as 200 million people who use WhatsApp’s web interface,wrote Oded Vanunu, Check Point’s group manager for security research and penetration.

“All an attacker needed to do to exploit the vulnerability was to send a user a seemingly innocent vCard containing malicious code,” he wrote.

The flaw was found by a Check Point researcher, Kasif Dekel. He found that the Web version of WhatsApp failed to properly filter electronic business cards in the vCard format.

Dekel found it was possible to change the file extension for a vCard to .bat, or a batch executable script. WhatsApp thinks a user is just receiving a vCard, but it’s actually executable code.

“This means once the victim clicks the downloaded file (which he assumes is a contact card), the code inside the batch file runs on his computer,” Dekel wrote.

An attacker just needs the victim’s phone number to send the malicious code and for the recipient to accept it.

Check Point disclosed the flaw to WhatsApp on Aug. 21, and WhatApp released an update for Web clients on Aug. 27. The up-to-date version is v0.1.4481.

Check Point waited until Tuesday to publicly disclose the vulnerability.

15 best antivirus & best free antivirus for PC and laptop UK

The 15 best free and paid antivirus programs for your PC or laptop in the UK in 2015. Best Antivirus reviews, tests and ratings. Where to buy antivirus. Best Windows antivirus for PC and laptop. (See also: best security software programs of 2015.)

If you’ve just downloaded Windows 10 or bought a new Windows 10 PC, don’t forget that it will need some help to keep it working as well as it does right now. And that means installing security software. Here we round up the best free antivirus and best paid antivirus for Windows 10, plus older Windows operating systems running on your PC or laptop. (See also:best business antivirus 2015 UK.)

Best antivirus: Why you need antivirus – What is antivirus?

Antivirus software detects, and then prevents, disarms or removes malicious programs or malware, often referred to as ‘viruses’. Antivirus doesn’t offer a perfect solution to the problem of malware, but it is a critical first step to securing your PC or laptop. To help prevent viruses infecting your PC you must install antivirus, and then regularly update your antivirus software. All of the antivirus software reviewed here will update automatically.

Best antivirus: How to choose antivirus

Malware is evolving faster than ever, but fortunately the latest generation of antivirus – or AV – is better equipped than ever to handle new threats.

In recent years, the technology that powers AV software has changed dramatically. An AV package you purchased a few years ago was able to stop known viruses and other known malware, but brand-new, unknown viruses proved more difficult. Newer products do a better job of stopping them.

For our antivirus tests we team up with AV-Test.org, a respected independent security-software testing lab based in Germany. AV-Test rigorously tests AV products from a number of leading security companies. The multifaceted testing procedure looks not only at how well an AV product can detect malware using traditional, largely signature-based methods (that is, employing a database of known malware types), but also at how well it can block brand-new, unknown malware. AV-Test also examines how well a security product can clean up after an infection in the event that a piece of malware does get through.

Every program in this list is worth your investment. The differences between the top few are relatively minor. The critical thing is to install one of these programs.

Best antivirus: what’s the difference between free antivirus and paid antivirus?

Our tests focus on paid-for and free AV products. Paid-for AV products usually offer better technical support and more comprehensive protection features than free programs, but free is free. Internet security suites go further still, offering firewalls, parental controls, identity theft protection and more.

Best antivirus reviews

Here we review the best antivirus programs you can buy or download in the UK right now. Securing your PC is, of course, about a lot more than antivirus. At the very least you need to run up to date antivirus, antispyware and a firewall. You’ll find that almost all of the best antivirus software we test these days forms part of an internet security suite: so all of the above and more is included.

The trouble is, some antivirus is better than others. They all offer a blacklist of known threats, and a whitelist of software that is known to be legitimate. But these days new threats emerge every day, and knowing what is friend and what is foe in real-time can be critical. And that’s where we come in. AV-Test challenges Windows security software to withstand threats both old and new, known and unknown.

We then combine that with our own experienced and expert tests of interface and system overhead. We test antivirus programs for how much (if at all) they slow down your PC or laptop, as well as how easy to use and how intrusive they are. Thus you can see from our regularly updated list of the best antivirus for PC or laptop, which is the best for you. Best antivirus for protection, best antivirus for performance, and best antivirus for value. Click through to read the individual antivirus reviews.

Excel logical formulas: 5 simple IF statements to get started

microsoft excel logo primaryIMAGE: ROB SCHULTZ
Excel functions, or formulas, lie at the heart of the application’s deep well of capabilities. Today we’ll tackle IF statements, a string of commands that determine whether a condition is met or not. Just like a yes-no question, if the specified condition is true, Excel returns one user-determined value and, if false, it returns another.

The IF statement is also known as a logical formula: IF, then, else. If something is true,then do this, else/otherwise do that. For example, if it’s raining, then close the windows,else/otherwise leave the windows open.

The syntax (or sentence structure; that is, the way the commands are organized in the formula) of an Excel IF statement is: =IF(logic_test, value_if true, value_if_false). IF statements are used in all programming languages and, although the syntax may vary slightly, the function provides the same results.

Remember: Learning Excel functions/formulas and how they work are the first steps toward using Visual Basic, Microsoft’s event-driven programming language. Here are five easy IF statements to get you started.

Past-due notices

In this spreadsheet, the customer’s payment due date is listed in column A, the payment status is shown in column B, and the customer’s company name is in column C. The company accountant enters the date that each payment arrives, which generates this Excel spreadsheet. The bookkeeper enters a formula in column B that calculates which customers are more than 30 days past due, then sends late notices accordingly.

A. Enter the formula: =TODAY() in cell A1, which displays as the current date.

B. Enter the formula: =IF(A4-TODAY()>30, “Past Due”, “OK”) in cell B4.

In English, this formula means: If the date in cell A4 minus today’s date is greater than 30 days, then enter the words ‘Past Due’ in cell B4, else/otherwise enter the word ‘OK.’ Copy this formula from B4 to B5 through B13.

excel logical formulas screen1
Use an IF statement to flag past-due accounts so you can send notices to those customers.

Pass/Fail lifeguard test

The Oregon Lifeguard Certification is a Pass/Fail test that requires participants to meet a minimum number of qualifications to pass. Scores of less than 70 percent fail, and those scores greater than that, pass. Column A lists the participants’ names; column B shows their scores; and column C displays whether they passed or failed the course. The information in column C is attained by using an IF statement.

Once the formulas are entered, you can continue to reuse this spreadsheet forever. Just change the names at the beginning of each quarter, enter the new grades at the end of each quarter, and Excel calculates the results.

A. Enter this formula in cell C4: =IF(B4<70,”FAIL”,”PASS”). This means if the score in B4 is less than 70, then enter the word FAIL in cell B4, else/otherwise enter the wordPASS. Copy this formula from C4 to C5 through C13.

excel logical formulas screen2
Use an IF statement to convert numeric scores to a pass-fail status.

Sales & bonus commissions

Wilcox Industries pays its sales staff a 10-percent commission for all sales greater than $10,000. Sales below this amount do not receive a bonus. The names of the sales staff are listed in column A. Enter each person’s total monthly sales in column B. Column C multiples the total sales by 10 percent, and column D displays the commission amount or the words ‘No Bonus.’ Now you can add the eligible commissions in column D and find out how much money was paid out in bonuses for the month of August.

A. Enter this formula in cell C4: =SUM(B4*10%), then copy from C4 to C5 through C13. This formula calculates 10 percent of each person’s sales.

B. Enter this formula in cell D4: =IF(B4>10000, C4, “No bonus”), then copy from D4 to D5 through D13. This formula copies the percentage from column C for sales greater than $10,000 or the words ‘No Bonus’ for sales less than $10,000 into column D.

C. Enter this formula in cell D15: =SUM(D4:D13). This formula sums the total bonus dollars for the current month.

excel logical formulas screen3
Use an IF statement to calculate sales bonus commissions.

Convert scores to grades with nested IF statements

This example uses a “nested” IF statement to convert the numerical Math scores to letter grades. The syntax for a nested IF statement is this: IF data is true, then do this; IF data is true, then do this; IF data is true, then do this; IF data is true, then do this; else/otherwise do that. You can nest up to seven IF functions.

The student’s names are listed in column A; numerical scores in Column B; and the letter grades in column C, which are calculated by a nested IF statement.

A. Enter this formula in cell C4:=IF(B4>89,”A”,IF(B4>79,”B”,IF(B4>69,”C”,IF(B4>59,”D”,”F”)))), then copy from C4 to C5 through C13.

Note: Every open, left parenthesis in a formula must have a matching closed, right parenthesis. If your formula returns an error, count your parentheses.

excel logical formulas screen4
Use a nested IF statement to convert numeric scores to letter grades.

Determine sliding scale sales commissions with nested IF statements

This last example uses another nested IF statement to calculate multiple commission percentages based on a sliding scale, then totals the commissions for the month. The syntax for a nested IF statement is this: IF data is true, then do this; IF data is true, then do this; IF data is true, then do this; else/otherwise do that. The names of the sales staff are listed in column A; each person’s total monthly sales are in column B; and the commissions are in column C, which are calculated by a nested IF statement, then totaled at the bottom of that column (in cell C15).

A. Enter this formula in cell C4:=IF(B4<5000,B4*7%,IF(B4<8000,B4*10%,IF(B4<10000,B4*12.5%,B4*15%))), then copy from C4 to C5 through C13.

B. Enter this formula in cell C15: =SUM(C4:C13). This formula sums the total commission dollars for the current month.

Use a nested IF statement to calculate different commissions based on different percentages.

New Opera Mini 11 ‘high mode’ eases up on compression to show you more content

opera mini 11OPERA BLOG
Opera Mini is giving you some more choice in how blazing fast you want to browse the web.

While the browser still compresses web content on its own servers in order to save you time and data, you can now choose from two different speed lanes: High or Extreme.

With the latter, you will see fewer details on a webpage but get it quicker than if you go for High compression. Sometimes Opera may cut out images or other details that you may actually want to see.

Opera Mini 11 is rolling out now in the Play Store. You can also get the latest version fromAPK Mirror.

The story behind the story: Opera Mini is a great browser if you want to rack up less data usage on your monthly plan. That’s because Opera compresses web content on its own servers, delivering you a lighter load. Chrome does some of this, but nowhere near as aggressively as Opera. With the new update, you now can opt for more detail over blazing speed.

Windows Media Center lives on with unofficial Windows 10 version

windowsmediacenter1
It turns out that Windows Media Center can run on Windows 10 after all.

Although Microsoft has officially discontinued its old living room PC software, some users on the My Digital Life forums have apparently patched Windows Media Center to run on Microsoft’s latest operating system.

The workaround was first spotted by WindowsBlogItalia (Google Translate link), which provides a link and installation instructions.

Why this matters: While Microsoft has claimed that hardly anyone uses Windows Media Center anymore, it remains a popular program among hardcore home theater PC users, many of whom are avoiding Windows 10 so they can keep using the living room software. This workaround could let users enjoy the benefits of Windows 10 without giving up Windows Media Center, but we’d still advise against it.

Words of warning for HTPC diehards

Before you get too excited about this bootleg Windows Media Center version, it’d be wise to keep a few things in mind: There’s no guarantee this program is safe, especially given that the installation involves running a process to automatically modify your system registry. Unauthorized distribution of Microsoft programs could wade into legally murky territory as well.

Even the Mega-hosted download itself is somewhat sketchy, as you must make sure to select “Download through your browser” option instead of installing Mega’s sync tool.

Instead of installing this version of Windows Media Center, you might first consider some alternatives. If you use WMC for watching and recording live over-the-air TV, the free NextPVR can be just as good when you follow our setup instructions. (On the downside, NextPVR can’t handle copy-once protected cable content.)

For local media playback, free programs such as Kodi and MediaPortal provide a TV-friendly interface, and the former can even hook into NextPVR to integrate your broadcast TV recordings. There are also free alternatives for DVD playback, which according to Microsoft was the most popular use for Windows Media Center.

And if all else fails, you can just roll back to Windows 7 or Windows 8.

Uber Plans to Enter 100 More Chinese Cities Over the Next Year

U.S. ride-hailing service Uber Technologies Inc will enter 100 more Chinese cities over the next year, doubling a previous goal set just three months ago, Chief Executive Travis Kalanick said on Tuesday.

Uber’s China unit currently operates in almost 20 cities, Kalanick said at an event in Beijing held byUber investor Baidu Inc.

The speech comes a day after Kalanick said the China unit had raised $1.2 billion (roughly Rs. 8,005 crores) during ongoing fundraising, while people familiar with the matter told Reuters that larger local rival Didi Kuaidi had brought in $3 billion.

The two firms are spending heavily to subsidise rides and gain market share, betting on China’s Internet-linked transport market becoming the world’s biggest and most lucrative.

“When we started this year, we were about one percent market share. Today, nine months later, we’re looking at about 30 to 35 percent market share”, Kalanick said. He did not specify whether that market was for all ride-hailing services including taxis, where Didi Kuaidi dominates, or just for private cars.

Uber also welcomes new regulations expected later this year governing ride-hailing services in China, Kalanick said.

At the event, Baidu, China’s Internet search leader, demonstrated a voice-operated artificial intelligence smartphone assistant for finding nearby offline services, which could also control a robot reminiscent of Disney’s WALL-E.

After the Baidu slot, Kalanick spoke of the importance of Uber’s relationship with the Internet firm.

“We can get introductions to the city governments, the government officials that want to shepherd our kind of innovation and our kind of progress into their cities,” he said.

During the speech, Kalanick adopted the language of Chinese officialdom, riffing on favoured Communist Party subjects such as harmony and stability.

“Progress is something we see the government be incredibly open to, whether it be about more jobs and less pollution, less congestion on the streets, better utilisation of infrastructure, that kind of progress always has to be in harmony with stability and that is one of the big things that we partnered with the government on,” he said.

Skype Messaging Beta for Windows 10 Mobile Quietly Released

Microsoft has quietly released a beta version of Skype’s new messaging app for Windows 10 Mobile-powered devices. The new app, which aims to replace the stock messaging client on Windows 10 Mobile handsets, offers messaging as well as video calling features.

The Skype universal app is Microsoft’s new approach with Skype, wherein it wants to more prominently place its popular voice over IP calling and texting service in its products and services. It offers instant messaging, texting, phone calls, video calls, and support for emoticon. You will be, however, required to sign in with your Microsoft account to use the service.

“Skype Messaging, Calling and Video ‘Preview’ is a new way to experience Skype features. It integrates individual Skype features where you’d expect them – Skype messaging into Messaging and Skype calling into Phone apps for the fastest way to make calls and send messages”, the app description of Skype Messaging, Calling and Video, as it is called on the Windows Store, read. “It also adds quick access to Skype video calling. With Skype built in, you’ll be able to reach anyone who uses Skype on iPhones, Androids, even PCs with just a couple of clicks.”

The feature as of now isn’t available on Windows Phone handsets running Windows Phone 7 or 8, or 8.1 The company is also officially yet to announce the availability of the beta app for Windows 10 Mobile testers. The official announcement could come alongside the release of a new Windows 10 Mobile preview build.

Microsoft is expected to release Windows 10 Mobile, the edition of the new operating system for smartphones, later this year with the launch of new flagship smartphones. To bolster the platform, Microsoft has made it easier than ever for developers to port their apps from iOS or Android to Windows Phone.

Hey Bob Wants to Solve Bengaluru’s Traffic Problem With Bike Taxis

While Bengaluru authorities are looking to work with the city’s tech community to solve its traffic problem, another startup has an innovative fix for the city’s traffic jams.

Hey Bob, launched last week on Google Play, wants to bring an on-demand model to motorcycle or bike taxis, like Uber and Ola do for regular taxis.

The firm writes that two wheelers will reduce traffic congestion on roads, at a cost lower than cabs. “Not only will this reduce traffic on the roads, it will also reduce carbon footprint and bring back the city’s green glory,” the Google Play description reads.

It seems like the only thing that the startup is waiting for, is state sanction. “We are waiting for the guidelines from the State transport, and once the guidelines are out, we will start our operations,” said Vishal Kumar, one of the co-founders of Hey Bob, in a phone conversation with NDTV Gadgets, adding that there are many others who are working on this concept.

“That’s an external factor, we do not have control over. The state government is working on regulating this entire idea, Once the guidelines are announced, it will be out in the media,” he said.

The startup is in bootstrap mode, and is in talks with investors. Kumar said that his firm was interested in piloting the service first in Bengaluru, and is working on background verification of its riders, and was focused on launching a bike taxi app as a primary use case. “We don’t want to divert our attention and collapse,” he said.

Mumbai-based HeyTaxi, an on-demand parcel delivery and transport service on two wheelers, had to shut its operations a week after its launch in June, as the state’s motor vehicle rules did not allow such operations.

Pornography-Based Android Ransomware App Discovered by Researchers

Security researcher firm Zscaler has discovered a new Android ransomware that is said to use pornography to snare users.

The security firm claims that the app named “Adult Player” clicks an image of the user secretly from the front-camera of the device and starts displaying it on the ransomware screen along with a message demanding $500 (approximately Rs. 33,250). The malware reportedly locks the device and only unlocks when it receives the ransom from the user. The firm explains that many users download such apps considering them video players for pornography content.

Zscaler details that on opening the app for the first time, it asks for admin rights from users. On getting the permission, it asks users to “Activate” the app, which the researcher claims is a fake update page.

“The malware then loads another APK named test.apk from its local storage using a technique referred to as a reflection attack. Reflection is the ability of a program to examine and modify the behaviour of an object at run time, instead of compile time. The ransomware checks whether front camera is available or not. If available, it clicks photo of the victim while he/she is using the app and displays the image on ransom page,” notes Zscaler.

It’s worth noting that the Adult Player app is not available via Google Play and is only available via third-party stores and needs to be side-loaded.

“The ransom screen is designed to stay persistent even at reboot. It does not allow the user to operate the device and keeps the screen active with ransom message,” writes security firm.

It adds that there is no way ransomware can be deleted from device’s Settings as the malware is designed to stay “stagnant on screen” and does not allow uninstallation.

Zscaler suggests some ways to get rid of such ransomware, including booting the device into safe mode after which users should first remove administrator privilege. Once done, users can uninstall the app via Apps in Settings. To avoid such ransomware, the security firm suggests users download apps only from trusted app stores.

To participate in this Bingo-like battle, you and your opponent choose a matchup—the Sept. 10 Steelers vs. Patriots game, for example. Each of you is given a game board of 16 randomly generated events that will likely happen during the football game. The goal is to be the first to connect a string of four consecutive events. “Connecting” gets you on the leader board where you’re ranked with other top players. As a bonus, a built-in chat feature lets you talk trash throughout your match.

Unlike other second-screen apps that can frequently distract you from game, NFL Connect keeps you more engaged, because success requires you to stay focused on the on-field action so you can react and swap game tiles as plays unfold. Just don’t spike your phone when you score.

SportsYapper

SportsYapper lets you talk about the game with other viewers in real time.

Venting your football frustrations to the general population on Facebook or Twitter is unsatisfying for you and downright annoying for your friends and followers. SportsYapper offers a more welcoming forum where your opinions and rants will always find a sympathetic ear.

Essentially, SportsYapper creates chat rooms around specific teams and live games where you can hang out and “yapp” with other fans. You get 300 characters to comment, which should be plenty to express your joy over your team’s last-second win or to debate a ref’s controversial call. When you have a meeting of the minds with another fan, you can give them a “high five,” the SportsYapper equivalent of a Facebook “like.”

Beyond sports chatter, the free app lets you upload and search photos of game gatherings, and it will alert you when a game is about to start or when a friend logs in.
