Wi-Fi Security feature foolproofs your network connections both in public and at home

Wi-Fi Security feature protects your network connections both in public and at home

Protect your Wi-Fi connections using Avast’s Wi-Fi Security feature.

Wi-Fi Security is a feature that is available for Android users within the Avast Mobile Security app as well as within Avast SecureMe for iOS. The feature’s job is to scan Wi-Fi connections and notify you if it finds any security issues including routers with weak passwords, unsecured wireless networks, and routers with vulnerabilities that could be exploited by hackers.

While conducting user testing, we found that 22% of Avast Mobile Security users make use of the Wi-Fi Security feature, making it the 2nd most used feature within Avast Mobile Security.

“Avast SecureMe and Avast Mobile Security offer users a simple, one-touch solution to find and choose safe networks to protect themselves from the threat of stolen personal data,” said Jude McColgan.

Wi-Fi Security scan notifies you of any issues that are detected

From all the users who tested the Wi-Fi Security feature, more than 10% of the scans performed returned some kind of problem, such as the use of non-encrypted passwords or a router that is susceptible to security threats. The Wi-Fi Security feature currently performs checks for the following four key elements:

  • Non-encrypted, unsecured wireless networks
  • Networks with weak encryption
  • Weak router passwords
  • Routers with known security issues

What’s the risk that my personal data will be stolen?

If you use unsecured Wi-Fi when you log in to a banking site, for example, thieves can capture your log in credentials which can lead to identify theft. On unprotected Wi-Fi networks, thieves can also easily see emails, browsing history, and personal data if you do not use a secure or encrypted connection like a virtual private network (VPN). See our global Wi-Fi hacking experiment to see how widespread the threat really is.

Wi-Fi Security offers two solutions to defend against malware threats

After the Wi-Fi Security feature has scanned your device, you’re presented with two options:

1) Launch Avast SecureLine VPN

2) Click the ‘How to resolve’ button

The first of the two options is meant to be used when you’re connecting to public networks – it’s ideal for cafes, airports, or hotels. On the contrary, users should opt to resolve detected threats if they’re browsing at home using their own devices. When taking this route, you’re redirected to the Avast website in order to set up your router in accordance with our guidelines.

How do I get the Wi-Fi Security feature onto my device?

Avast SecureMe will soon be available in the iTunes Store. Before its widespread release, we will be conducting an invitation-only public beta test. Please sign up hereand the SecureMe team will contact you. If you have already downloaded Avast Mobile Security for Android then you’re all set to start using the Wi-Fi Security feature (you’ll find the “Wi-Fi Security” button on the app’s dashboard). For those yet to download Avast Mobile Security, it is available now from the Play Store.

Apple Leaves CNNIC Root in iOS, OSX Certificate Trust Lists

When it was revealed late last month that a Chinese certificate authority had allowed an intermediate CA to issue unauthorized certificates for some Google domains, both Google and Mozilla reacted quickly and dropped trust in CNNIC altogether, Apple has kept the root certificates in its trusted store for both iOS and OSX. Apple on Wednesday released […]

Apple iOS 8.3 Includes Long List of Security Fixes

Apple has released iOS 8.3, a major security upgrade for iPhone and iPad users that includes patches for more than three dozen vulnerabilities. The new version of iOS has security fixes for several vulnerabilities in the mobile operating system’s kernel, a handful of code-execution bugs and a long list of WebKit vulnerabilities. Apple also patched […]

Apple fixes FREAK flaw in OS X and iOS

What is FREAK?

By exploiting the Factoring RSA Export Keys vulnerability in SSL (FREAK), an attacker could intercept the network traffic between entities running any implementation of the vulnerable protocol and decrypt the secure communication. In other words, the attacker is able to act as a man-in-the-middle and decrypt the secure traffic between the client and the server.

The well known OpenSSL library, Apple’s Secure Transport, and Microsoft’s Secure Channel (which is impacting all supported versions of Windows) have all been found vulnerable to this type of attack.

IMG_0059The flaw resides in the fact that the SSL/TLS encryption was forced to use a weaker cipher suite (so called “export grade”) with a 512-bit key that could be broken with today’s technology in a few hours.

Apple is describing the affected area as a “Secure Transport vulnerability which allows an attacker with a privileged network position to intercept SSL/TLS connections”.

The security update 2015-002 which fixes FREAK is available for OS X Mountain Lion v10.8.5, OS X Mavericks v10.9.5, and OS X Yosemite v10.10.2.

The iOS 8.2 is available for iPhone 4s and later, iPod touch (5th generation) and later, and iPad 2 and later.

What should you do?

Apple’s security update for MacOS also includes mitigation for arbitrary code execution by leveraging flaws in iCloud Keychain recovery, IOAcceleratorFamily and IOSurface and the Kernel (OS X Yosemite).

For the iOS, Apple patched bugs in CoreTelephony, which caused the device to restart and buffer overflows in iCloud Keychain which allow an attacker with a privileged network position to execute arbitrary code.

Even if CVE-2015-1067 also known as FREAK is more theoretical than most vulnerabilities affecting the SSL protocol and its implementations (Heartbleed, Poodle), it is strongly advisable to apply the update.

Usually, the update comes over the wire, so follow the known procedures for each device to apply it:

  • iOS: go to Settings ->General -> Software Update
  • Go to Updates (or Software Updates for older versions) and click Update All.

Why iOS devices could be one tap away from disaster

Users who don’t pay attention to warning messages on their iPhones or iPads run the risk of becoming infected with malware that can steal their personal information such as text messages, contact lists, pictures and even their location.

If you’ve followed our advice in the past for keeping your iOS device secure, you’ll know that you should be doing the following:

  • Install updates – keep up to date, and that includes your apps too.
  • Keep a backup – use iCloud or Dropbox for photos and backup your device.
  • Never “jailbreak” – this is the method for breaking the factory security.
  • Activate anti-theft – such as “Find my iPhone/iPad” to locate a lost or stolen device.

BUT despite this, did you know you could still be just one tap away from disaster?

As reported in Macworld, security researchers uncovered spyware dubbed “XAgent” that is delivered via a phishing attack and can spread to other iOS users via contacts in your address book.

For more tips on staying safe from phishing, check out my blog “How To Protect Yourself from Phishing Attacks”

The good news is that you can do something about this, as all the users affected by this particular threat (and previous ones using the same technique) almost certainly “infected themselves” by ignoring vital warning message prompts.

Apple advise iOS users here to be mindful to only download and install apps from the Apple App Store and to be cautious of so-called “enterprise apps” that are only intended for employees of large businesses.

Therefore, if you don’t work for a company that is specifically requesting you to install an app and you see these following prompts – make sure you answer them correctly to protect yourself from inadvertently installing malware.

iOS Install Warning

To protect yourself in this example you click CANCEL

 

iOS Trust Warning

 

To protect yourself in this example you click DON’T TRUST

You might have also seen a similar Trust or Don’t Trust option available when connecting your iPhone or iPad to a friends computer – and again the safer option is always Don’t Trust.

Until next time, stay safe out there.

iOS users facing new storage challenges

News emerged recently that Apple has been challenged about storage on their iOS devices.

According to news sources, Apple has come under fire for the size of their latest operating system iOS8 which can apparently occupy up to 23.1% of the devices total storage.

On top of this, the upgrade from iOS 7 to iOS 8 alone can take up more than 1.3 Gigabytes of storage space.

While the storage statistics for iOS 8 might be surprising, it’s important that iPhone and iPad users realize that often their storage can be taken up by multiple unnecessary files and not just operating system files.

Operating systems are not the only files that bloat and grow over time; in fact it’s quite common for updates to systematically increase an app’s footprint on our devices as new features and enhancements are added

That’s why it’s very important to regularly clean out your mobile device, get rid of unwanted or unneeded files and apps and create space for the things you really want.

To help you do this, AVG has developed iOS Cleaner as part of the AVG PC TuneUp performance suite. iOS Cleaner can help you reclaim back valuable storage space on your iPhone or iPad devices by locating and removing duplicate files and unnecessary clutter and temporary files.

We’ve also prepared this easy to follow guide to help you get started.
