Avast at Virus Bulletin Conference 2015

Our team had a wonderful time meeting and networking with the crème de la crème of security industry professionals at this year’s Virus Bulletin Conference in Prague, of which we were a proud platinum sponsor. Throughout the conference, a handful of Avast employees presented talks a variety of today’s most prominent security-centered topics. For those who weren’t able to make it to the conference, we’d like to provide a brief recap of the content that was covered.

Taking a close look at denial of service attacks

Avast senior malware analysts Petr Kalnai and Jaromir Horejsi discuss distributed denial-of-service (DDoS) attacks while Pavel Baudis, co-founder of Avast, serves as a moderator of the conference.

Avast senior malware analysts Petr Kalnai and Jaromir Horejsi discuss distributed denial-of-service (DDoS) attacks while Pavel Baudis, co-founder of Avast, serves as a moderator of the conference.

In their presentation, “DDoS trojan: a malicious concept that conquered the ELF format“, senior malware analysts Petr Kalnai and Jaromir Horejsi discussed the serious issues relating to distributed denial-of-service (DDoS) attacks.

Abstract: DDoS threats have been out there since the Internet took over half of global communication, posing the real problem of denial of access to online service providers. Recently, a new trend emerged in non-Windows DDoS attacks that was induced by code availability, lack of security, and an abundance of resources. The attack infrastructure has undergone significant structural, functional and complexity changes. Malicious aspects have evolved into complex and relatively sophisticated pieces of code, employing compression, advanced encryption and even rootkit capabilities. Targeted machines run systems supporting the ELF format – anything from desktops and servers to IoT devices like routers or digital video recorders (DVRs) could be at risk.

Making technology simpler: Thanks to my mother

Some days ago we wrote about scams targeting senior citizens. This group is at risk because generally speaking, they have less computer education than younger people who have grown up in the digital world. I recommended the reading to my mother, thinking she will benefit from it. She thanked me, but said that there were “some things” she did not understand.

Learning to surf internet

Friends and family can help senior citizens enjoy a safe online experience

In the Avast blog we do our best to write in simple terms. However, we know much more about security and, quite frequently, explains things in technical writing. So, I’ve take some time to write what will be useful for your mother (and mine). What about recommending her to read this?

10 ways to ensure your security while shopping online

That online shopping increases day by day is not news. If you are an average user, you are probably already aware of the normal precautions and have taken them yourself. Ease of use and convenience when browsing for different products or searching for the best prices has improved greatly. However, at the same time, online threats and frauds have also increased exponentially. Therefore, from time to time, all of us must review our behavior and think again if our habits are secure.

Follow a few simple tips to stay safe while shopping online

Follow a few simple tips to stay safe while shopping online

Best practices while online shopping

1. Use your own computer or mobile device when shopping. It seems obvious, but you cannot trust a computer that does not belong to you, even your best friend’s computer. It might not have appropriate protection and it could already be compromised by malware. So, always use your own device, install an anti-malware solution and before you start doing anything that involves your money, scan your network to discover if it is safe.

Microsoft releases emergency Windows patch after discovery of critical security flaw

With the release of their newest operating system just days away, now is not the most convenient time for Microsoft to be facing and dealing with security bugs. However, two thirds of all 1.5 billion PCs operated by Windows across the globe were recently left vulnerable due to a security flaw found in nearly every version of Windows, including Windows 10 Insider Preview.

If you use Windows, the time to update is now!

If you use Windows, the time to update is now!

The flaw (MS15-078) lies within the Windows Adobe Type Manager Library and can be exploited by cybercriminals to hijack PCs and/or infect them with malware. Users can be attacked when they visit untrusted websites that contain malicious embedded OpenType fonts. Microsoft explains more about the threat in a security bulletin advisory:

An attacker who successfully exploited this vulnerability could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

There are multiple ways an attacker could exploit this vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage that contains embedded OpenType fonts. The update addresses the vulnerability by correcting how the Windows Adobe Type Manager Library handles OpenType fonts.

The flaw has been classified as critical, which is Microsoft’s highest measured level of threat. Anyone running Windows Vista, Windows 7, Windows 8 and 8.1, Server 2008, Server 2012 and Windows RT are affected by the flaw. Microsoft’s online Security TechCenter includes a full list of affected software and additional vulnerability information.

Do third-party app stores pose a threat to mobile security?

Android Malware

Malware detected on Android

Over time, we’ve noticed the presence of some fairly heated user debates disputing the necessity of security or antivirus apps for Android devices. This could have been sparked by our recent post which argues that you can’t always rely on the security of Google Play or because of the myth that antivirus companies create viruses to sell more software.

Certain security gurus claim that if users stick to downloading and purchasing apps using only the Google Play Store, nothing bad will happen to their devices. However, we found that this line of thinking is not 100% correct, as was demonstrated through the discovery of a rogue Dubsmash app or in the infamous case of apps on Google Play posing as games and infecting millions of users with adware. Despite these findings, there are some users who still feel that they’re safe whenever using Google Play. This feeling of false security could have negative consequences; for example, when your data or financial information is stolen or when you have to resort to resetting your device in order to cleanse it of malware.

So, we know we can’t rely on the Google Play Store all the time, but are third-party stores more secure? Of course not. In this case, how is it still possible that it’s not a problem to use third-party stores? First of all, it’s necessary to point out that there are certain legitimate and clean third-party stores, such as Amazon and FDroid. At the same time, there are tons of shady stores and even more black market .apk files promising to deliver you the latest features of a cracked app.
