Cybersecurity tips for business travelers

business trip - working late

Sensitive business data is at risk when you travel. Take precautions to protect it.

Cybersecurity is not limited to your office or home. Nowadays, many of us use the same devices for work and personal business, so when traveling we need to be extra diligent to protect our devices and the data we have on them. If you use common sense and a bit of Avast technology, all your devices – laptops, smartphones, and tablets, can remain secure wherever you are.

Here are a few things you can do before you go and while you’re on-the-road:

1. Install antivirus protection. Your first and best line of defense on your PC or Android device is antivirus protection. Install it and make sure it is up-to-date.

2. Keep your operating system and software up-to-date. Hackers take advantage of software with security holes that have not been plugged, so take time regularly to make sure that your software and apps have patches and updates applied.

3. Lock down your device. Make it a habit to lock your PC and phone with a PIN, password, or even a fingerprint. Avast Mobile Security even allows you to password-protect your apps. Before you travel, make sure your critical apps, like access to your bank, are protected.

Avast Mobile Security users can help develop a new app

We all know how bothersome finding and connecting to Wi-Fi networks in public places can be — often, we encounter frustrating roaming fees or slow connection speeds in crowded spaces. At Avast, we want Wi-Fi connection to be a safe and simple process for our users. As a result, we’re currently working on new product that will help people to detect and connect to public Wi-Fi networks without any security risk.

Introducing Avast’s new product pioneering program

We’ve recently rolled out a new feature within Avast Mobile Security called the product pioneering program. This program helps harvest nearby Wi-Fi hotspots available for users when they need to connect to public Wi-Fi networks. The feature also supports the creation and growth of our own trustworthy and up-to-date hotspot database, which we need in order to deliver information about nearby Wi-Fi hotspots to our users. As we know that Avast users place great importance on their security and privacy, we are asking our users to lend us a helping hand in collecting and identifying hotspots in their local surroundings. This requires us to request the GPS position permission of our users during the installation or upgrading process of Avast Mobile Security.

Upon installing or upgrading Avast Mobile Security, users will receive an in-app notification that informs them of our product pioneering program. If a user chooses to opt in to the product pioneering program, it is only then that his or her GPS location information will actively be gathered.

Going on a trip? Be sure to pack Wi-Fi protection.

Protect your devices when on unsecured Wi-Fi with Avast SecureLine VPN.

Protect your devices when on unsecured Wi-Fi with Avast SecureLine VPN.

Relying on your hotel to protect you when using their free guest Wi-Fi  is not a good idea.

Even the best hotel chains are vulnerable to hackers, so having a Virtual Private Network (VPN) is vital for your protection. I will tell you how easy it is to use below. But first, here’s how cybercrooks can get their victims:

One way is through buggy equipment such as the critical vulnerability discovered last March in ANTlabs’s InnGate product used by 277 hotels, convention centers, and data centers in 29 countries. The InnGate provides temporary guest access to a Wi-Fi connection. By breaking into this piece of equipment, an attacker gets full read and write access to a Linux file system and from there can launch attacks against guests on the affected hotel’s Wi-Fi.

Another tactic hackers take is to create a fake Wi-Fi network, call it something innocuous like “Hotel Guest Wi-Fi”, and lure unsuspecting victims to their rogue connection. What the hackers do is set up their own access point and hope you’ll connect to theirs instead of the public Wi-Fi network.

What do hackers want?

It depends on who you are and what information you have on your devices. For normal people with normal jobs, typically, the hacker can watch your online activity, read your email, steal your account passwords and if they go deeply enough, potentially steal your credit card information, which is the precursor to identity theft. “There is seemingly no limit to what they could do,” say the researchers who discovered the InnGate vulnerability.

Victims’ laptops or mobile devices can be also be infected with malware. Last year, the DarkHotel cyberspies gained access to the computers of high-level executives, government agencies and NGOs, and U.S. executives traveling in Asia, probably to steal nuclear secrets.

How do you protect yourself on free Wi-Fi?

Windows 10 Service Agreement upsetting privacy watchdogs

Targeted advertisements based on your search history, location tracking, Wi-Fi sharing, torrent style updates – features that share too much are getting privacy watchdogs in a tizzy.


Windows 10

Reviewers and consumers alike are happy about the new Windows 10, but now that there has been time to read through the 45-page long consolidation of Service Agreements into one central agreement (which also covers Bing, Outlook, and Xbox Live) some data protection advocates are taking issue with certain features. The European Digital Rights (EDRi) organization summarized that “Microsoft basically grants itself very broad rights to collect everything you do, say and write with and on your devices in order to sell more targeted advertising or to sell your data to third parties.”

Sharing your business to keep yourself organized

Anyone remember this assistant?

Anyone remember this assistant?

One of the useful but controversial features in Windows 10 is a personal digital assistant called Cortana, similar to Apple’s Siri (and light years away from Clippit, Windows 95 office assistant!) Cortana can set reminders, recognize your natural voice, use information from Bing to answer questions, and of course save all that information in order to provide personalized search results, which basically means you are being profiled so targeted ads can be presented to you (Facebook and Google does that too). Cortana can be disabled and you can opt out of personalized ads.

Computer-aided sniper rifles the latest things controlled by hackers

via Wired

via Wired

For those of you keeping track, you can add high-tech sniper rifles to the growing list of Things That Can be Hacked. The vulnerability that allowed two security researchers to break into the computer guidance system of a sniper rifle is the same that allows hackers to access baby monitors and home routers. Simply put, the default Wi-Fi password, which was locked by the manufacturer, allowed anyone within range to connect. The typical range is up to 150 feet (46 m) indoors and 300 feet (92 m) outdoors.

In advance of the Black Hat conference this month, security researchers Runa Sandvik and Michael Auger, have demonstrated that they can hack TrackingPoint precision-guided firearms.

The TrackingPoint rifles can make a sharpshooter out of a novice. This is thanks to the computer-aided sensors including gyroscopes and accelerometers which take into account all the factors that a sniper scout would look for; wind, speed of the target, distance, snipers orientation, ammunition caliber, even curvature of the earth.

I asked Steve Ashe, a veteran of Desert Storm and Desert Shield, who collaborated closely with the sniper team what he thought about such technology. “Trained scouts and snipers must master a set of physical and mental skills that is beyond the reach of most people. This type of rifle can never replace that. Besides being crack shooters, they are in excellent physical condition, able to do complicated calculations in their heads and have mastered field craft such as land navigation, stalking and range estimation.”

One of the features of the TrackingPoint rifle is the ability to video stream your shot and share the view from the scope to another device connected via Wi-Fi. It’s this connection to Wi-Fi that turned out to be the weak point. The gun’s network has a default password that cannot be changed.

Are the hacks on Mr. Robot real?

Last night the pilot episode of MR. ROBOT, a new thriller-drama series aired on USA Network.

The show revolves around Elliot who works as a cyber security engineer by day and is a vigilante hacker by night.

I watched the episode and then sat down with Avast security expert Pedram Amini, host of Avast’s new video podcast debuting next week, to find out if someone like you or me could be affected by the hacks that happened in the show.

In the second minute of the episode we see Elliot explaining to Rajid, owner of Ron’s Coffee, that he intercepted the café’s Wi-Fi network, which lead him to discover that Rajid ran a child pornography website.

Stefanie: How likely is it that someone can hack you while you’re using an open Wi-Fi hotspot?

Pedram: Anyone with a just a little technical knowledge can download free software online and observe people’s activities on open Wi-Fi. We went to San Francisco, New York, and Chicago for a Wi-Fi monitoring experiment and found that one-third of Wi-Fi networks are open, without password-protection. If you surf sites that are unprotected, meaning they use the HTTP protocol, while on open Wi-Fi, then anyone can see, for example, which Wikipedia articles you are reading, what you’re searching for on Bing, and even see what products you are browsing for on Amazon and eBay, if you do not log in to the site.

Stefanie: Wow! That’s a bit frightening… How can I protect myself then?

Samsung phones vulnerable to hacker attack via keyboard update


Samsung Swiftkey vulnerability puts Samsung devices at risk

600 million Samsung mobile devices are at risk. Image source:

We rely on our apps. Everyday we use our favorite ones to check news, the weather for our next trip, and communicate with our loved ones. Some apps, especially the system ones, are continuously in use, even if they are not the foremost app on your screen. The keyboard is one of them.

Recently, a dangerous vulnerability was discovered in the most popular keyboardSwiftKey. If you have a Samsung S6, S5, and even a S4 running the stock operating system, you’re at risk. The app always checks for language updates, but this process is not performed in a secure way. If you’re connected with an open or public Wi-Fi, your phone is at risk of a very common and dangerous Man-in-the-middle attack. Your connection will be compromised and all the Internet traffic could be eavesdropped upon. That includes the passwords you’re typing in the very same keyboard, your financial information, everything.

To insure your security, you need to use a VPN when on Wi-Fi, since that’s when most updates are scheduled to occur. You probably already know what a VPN is and how it works. If not, you can find a lot of information in our blog. Our product, Avast SecureLine VPN, creates an encrypted tunnel for the inbound and outbound data of your Internet connection, blocking any possibility of a Man-in-the-middle attack.

But the story does not end here. If you use SwiftKey on an unsecured Wi-Fi, the attacker could also download malware into your phone or tablet. That’s a job for Avast Mobile Security & Antivirus (AMS). Some users think that we don’t need a security product for our phones. They also think that security companies exaggerate the need for a security app just to sell their products. AMS not only scans the installation process of apps but also checks the Internet sites you’re visiting and malicious behavior of any file in your device. You can install Avast Mobile Security & Antivirus on your Android device for free from the Google Play store.

NOTE: At the writing of this post, a patch for the vulnerability was provided to mobile network operators by Samsung. SwiftKey wrote on their blog, “This vulnerability is unrelated to and does not affect our SwiftKey consumer apps on Google Play and the Apple App Store.”
