Facebook Clickjacking: Will You Like Me?

FB_meme“Who wouldn’t want to have more likes on their Facebook page?” This is the motivation of a very trivial code to get more likes, but while other methods usually comprise of adding better content or advertising, this one is a bit easier, and much dirtier. Why not show the like button directly beneath your mouse cursor as you browse a website, make it invisible, and move it as you move your mouse?

The only thing the victim has to do is click; if they are logged in to Facebook, they will automatically like the Facebook page. And of course, it is not only about the number of likes, but each like means the victim will get all the information about this page on their news feed (until they unlike the page), and all friends will also see that you like it – so why not check it out themselves?

FB_clickjack_Like_ButtonThis method is possible due to Like Button, a social plugin for Facebook, made by Facebook developers. It is used properly on many legitimate sites, but when combined with CSS hiding and JS moving, the victim has no other chance. If you want to know how to minimize the impact of such tactics, or if you are more into technical details, read on.

Fake email spoofs AVAST

Malware samples received in the avast! Virus Lab Wednesday show that a spoofed email which looks like it has been sent from AVAST is spreading widely. Fortunately, AVAST detects this malware as Win32:Malware[Gen] and has been blocking the virus since 12:45 pm yesterday.

The email’s subject header says, “Your Order details and Additional information,” and the email message contains standard text that is sent when a person purchases a license from AVAST. The message includes an order number that is not authenticated and does not exist in the AVAST database.

The sender’s email address is This is a fake email address and was not created by AVAST. The email contains an attachment titled The attachment is a file that includes two file extensions – *.PDF.EXE – which is malware.

Our worldwide CommunityIQ sensors automatically detected and provided information to the avast! Virus Lab about these suspicious files, and the new threat was detected and neutralized immediately. So far, our virus lab has received 12,500 malware samples.

Avoid this attack by downloading the new avast! Antivirus 2014 for free.

Five wonderful things the Czech Republic has given the world

beer (1)
Where beer flows like water

The Czechs love their beer. Monks living in the region started brewing in monasteries just a few centuries AD. The Czechs gave the gift of Pilsner to the world back in the mid-1800s, and ever since then citizens have supported their own industry by consuming more beer per capita than any other country in the world. These days, Czechs drink on average about 161 liters of beer per person each year.  Not surprising when bottled beer is cheaper than bottled water!

“Beer is known to free up your brain for creative problem solving,” said Jindřich Kubec, Director of Threat Intelligence, “and since AVAST has some of the highest detection ratings of any antivirus out there, it shows that we are doing lots of “problem solving.” ;-)

Sweet success

Back in the day, refined sugar came in unwieldy big blocks that had to be sawed at, hacked, and cut through. This physical effort resulted in numerous boo-boos and aching fingers holding onto dainty tea cups (Czechs don’t always drink beer ;) ). One day, the wife of Jakub Kryštof Rad, the man who ran the local sugar refinery,  grew tired of having to bandage her appendages every time she wanted a little sweetener. She asked him why he couldn’t package sugar in a more manageable size for teacups. Mrs. Rad inspired her husband to create what we know today as sugar cubes.

“Speaking of sugar,” said Vladimir Saur, Traffic Manager at AVAST, “every day someone brings chocolate to the office, and we are living proof that dark chocolate improves brain function. Well, only when our boss leaves us at least a little bit!”

As unique as a fingerprint

CSI fans will dig what 19th-century physician and scientist Jan Evangelista Purkyně revealed in his work in physiology.  His discovery that all human fingerprints are unique and his subsequent classification of fingerprint patterns advanced criminology and forensic science.  A century later, Czech scientist Jan Janský learned that human blood could be classified into four distinct groups, which led the way to the A-B-O system we use today.

“Just like Sherlock Holmes hot on a the trail of a “whodunit” mystery, the researchers in the avast! Virus Lab follow clues to discover what malware does, why it does it, how to classify it, and most importantly, how we can stop it,” said Filip Chytrý , avast! Virus Lab researcher.

Mick Jagger lights up the castle

You will think you have entered a fairy tale when visiting the Czech Republic. With over 2,000 castles, the country has the highest density of castles, ruins, chateaux, and villas in the world. The most significant of them all is the Prague Castle, the largest medieval castle in Europe.

“One of the attractions to working for our great company, is its location. Prague is a fairy-tale city with magical beauty, said Marcela Římalová, Senior Worldwide Recruiter for AVAST Software. “After the Velvet Revolution, The Rolling Stones were invited by President Havel to play a concert. They noticed that the Prague Castle was dark at night, so they graciously paid for it and four of its grand halls to be illuminated. It’s a view we still enjoy today.”




avast! Free Antivirus

Powered, no doubt,historic-avast by Czech beer and chocolate, Pavel Baudiš, a young researcher at Prague’s legendary Mathematical Machines Research Institute came upon a sample of the Vienna Virus on a floppy disk. After he wrote a program to remove it, he showed it to his friend and colleague Eduard Kučera and, together they started what’s now the world’s most popular and trusted antivirus software. AVAST Software is celebrating its 25th anniversary soon and launching the newest version -  avast! 2014.

“When we started this company behind the Iron Curtain in 1988, we could not imagine that it would grow to protect more computers worldwide than any other firm,” said Eduard Kučera and Pavel Baudiš, founders of AVAST Software, “No one can say what the next 25 years will bring. But one thing is certain, the AVAST team – now spread over several countries – is talented, energetic, and committed to making sure that everyone in the world has access to computer security that works.”

avast! Free Antivirus wins VB100 award

vb_award_enAVAST Software, maker of the most trusted antivirus in the world, avast! Free Antivirus, has achieved a VB100 award in the latest Virus Bulletin VB100 comparative review. 

The VB100 award is given to those products that detect 100% of viruses “in the wild,” using the freshest malware sample sets available, as well as samples not previously seen. In this round, the testers also used a range of items including a wide selection of educational software, designed for use either in schools or in home-teaching environments. avast! Free Antivirus scored 100% for each malware set tested.

“The core sets were dealt with flawlessly, easily earning Avast a VB100 award for this month’s efforts,” said the Virus Bulletin experts conducting the test.

The second standard measured is the number of false positives generated when scanning. A false positive warning happens when a file is erroneously tagged as a virus or malware, when in fact the file does not possess such malicious code and is not a virus or malware. avast! Free Antivirus had zero false positives and got a perfect score on both standards showing it has what it takes to handle newly emerging malware and accurately detect previously unknown malware.

Speed and performance measures are also taken and avast! Free Antivirus earned the highest Stability rating, Solid: No issues observed, as opposed to Stable, Fair, or Buggy.

The Virus Bulletin annual conference, the premier technical event of the antivirus/security industry, will be held the first week in October in Berlin. AVAST will be attending, so we hope to see you there.

How schools can save big with AVAST Free for Education

Keeping kids safe while they are online is a major concern for educational institutions from schools to libraries to museums. Schools in the United States spend a lot of money on education technology—it was estimated at $56 billion dollars in 2012. That’s about $400 per student per year. A portion of that is earmarked for security software and support. In fact, an average school district pays over $14,000 for antivirus protection. Because of declining budgets, 5 percent of schools can’t even afford this protection.

AVAST gives away Security Software for FREE


AVAST offers avast! Endpoint Protection Suite software for FREE to schools, universities, libraries, and other educational institutions in the USA (and its territories). The award-winning security software is available for up to 30,000 devices, can be centrally installed and managed, and also protects servers – all at no cost to educational institutions. It’s free, and there is no catch or hidden surprises.

Linux Trojan “Hand of Thief” ungloved

A new threat for the Linux platform was first mentioned on August 7th by RSA researchers, where it was dubbed Hand of Thief.  The two main capabilities of this Trojan are form-grabbing of Linux-specific browsers and entering a victim’s computer by a back-door. Moreover, it is empowered with features like anti-virtualization and anti-monitoring. With the level of overall sophistication Hand of Thief displays, it can be compared to infamous non-Windows threats such as the FlashBack Trojan for MacOsX platform discovered last year or Trojan Obad for Android from recent times.

A detailed analysis uncovers the following structure of the initial file with all parts after the dropper being encrypted (hexadecimal number displays starting offset of a block):

avast! Mobile Premium: The Ultimate in Mobile Security

new AMSpost_img

More than 25 million Android smartphone and tablet users protect their precious devices with AVAST’s free security app. Today, we are happy to provide even more awesome features in our new premium version, avast! Mobile Premium.

The security of data on mobile devices is a growing concern. Over a quarter (26%) of mobile phone owners have lost their phone or had it stolen, and that means that photos, contacts, and personal information, and in a growing number of cases-  company data, is exposed to crooks. This data loss is exacerbated because nearly 50% of US smartphone owners do not back up their content.

avast! Mobile Premium can help you recover your lost phone and data with superior back-up and anti-theft technology.

Erect an invisible fence around your phone

Geo-Fencing is one of the clever anti-theft features of avast! Mobile Premium. You set up a perimeter, for example, around the coffee shop, and choose some actions like setting a loud alarm. If a sticky-fingered thief tries to take your phone outside of the perimeter when you are distracted by your mocha latte, the alarm goes off, or the phone is locked. Gotcha! Read more…
