Safer Internet Day 2019 0 185

Working together with your children for a better online experience

Beginning in 2004, Safer Internet Day has grown to become one of the landmark events in the online safety calendar. And this year’s theme, ‘Together for a better internet’, encapsulates a lot of the discussion we are seeing around online safety and cybersecurity. The topic is too complex a minefield for any of us to bear sole responsibility and, like all good things in life, we need to work together to bring about the best possible future.

What does it mean to work together where online safety is concerned? It could be an IT security company working closely with a consultation of parents to develop products, or parents and teachers working to ensure the online education of our young people. But what about children themselves? We put a lot of onus on finding the right solutions and products to protect our kids online, but one day those kids will grow up and live without online parental control. We should think about the best way to prepare them; ‘together for a better internet’ should mean working with our children to educate, inform and protect them, so they can stand the best possible change of making the right decisions for themselves.

That’s not to say that software doesn’t play a crucial role, and ESET would encourage all parents to take care over choosing the right parental control software on the family computer. When you are doing this though, we advise you do it together with your kids. Talk them through the programmes you’re installing and select your privacy settings together, discussing why you are doing it and the kinds of threats you’re protecting the family against. As part of this conversation you can talk to your children about what they’re doing online, who they’re talking to and what kinds of things they need to be careful about in day to day online. Many kids see control settings on the internet as a block to them having fun; what they need is someone to explain their function and reasoning. By having this discussion, you’re giving your kids an element of control and responsibility over their online activities which, when paired alongside the rules and software we all need to protect ourselves, should produce better results when it comes to their internet education.

The internet is such an integral part of our lives that the earlier you start talking to kids, involving them and teaching them about their online worlds, the better the results. Creating an open dialogue will always be more effective than just putting your foot down.

Set an example; whatever you expect your kids to do, make sure you are also doing. The online world represents dangers for all of us and we can all benefit from a few more precautions. If you’re asking your kids to cover their webcam when they’re not using it, then make sure you also do it. If you’re restricting their screen time, then think about setting yourself some boundaries as well. With the damaging effects of too many screens on our health and wellbeing, it’s unlikely to have any negative repercussions.

ESET’s software, such as its ESET Parental Control, places a large emphasis on parents and children working together. It helps them to navigate online, manage what apps and websites they use, and decide – together – what’s good for them. One of the key features is age-based filters which helps to manage which apps children can and cannot access, allowing parents to consider the right restrictions for their children and to not just impose a blanket ban. Other features include setting time limits on when children can play on their devices and creating exceptions that kids can request. Parents can even send their children messages which they must acknowledge before they can continue to use their devices.

It’s elements such as these that allow children to be involved in the monitoring of their safety, and truly help parents to work together with their kids for a better internet and the best possible online world.

Approximately US $150,000 worth of Ethereum-based cryptocurrency stolen 0 739

Online cryptocurrency website MyEtherWallet.com has confirmed that some visitors could have been temporarily redirected to a phishing site designed to steal users’ credentials and – ultimately – empty their cryptocurrency wallets.

According to reports, whoever was behind the attack may have successfully stolen approximately US $152,000 worth of Ethereum-based cryptocurrency.

However,  MyEtherWallet may not have been at fault, as the website explained in its statement:

“This is not due to a lack of security on the [MyEtherWallet] platform. It is due to hackers finding vulnerabilities in public facing DNS servers.”

British security researcher Kevin Beaumont confirms in a blog post that some of MyEtherWallet’s traffic had been redirected to a server based in Russia after traffic intended for Amazon’s DNS resolvers was pointed to a server hosted in Chicago by Equinix.

For the scheme to succeed, someone pulled off a hijack of a crucial component of the internet known as Border Gateway Protocol (BGP), to reroute traffic intended for Amazon’s Route 53 DNS service to the server in Chicago. As a consequence, for some users, entering myetherwallet.com into their browser did not take them to the genuine site but instead to a server at an IP address chosen by the hackers.

The only obvious clue that a typical user might have spotted was that when they visited the fake MyEtherWallet site they would have seen an error message telling them that the site was using an untrustworthy SSL certificate.

It seems that the attackers made a mistake in not obtaining a valid SSL certificate.

Despite the error with their SSL certificate, the hackers haven’t done badly for themselves – both in this attack and in the past. Fascinatingly, the bogus MyEtherWallet website set up by the criminals was moving stolen cryptocurrency into a wallet which already contained some US $27 million worth of assets. Inevitably that raises questions of its own – have the hackers already made a substantial fortune through other attacks, or might their activities be supported by a nation state?

In a statement Equinix confirmed that a customer’s equipment at its Chicago data center was used in the hackers’ hijacking of Amazon’s Route 53 DNS service:

“The server used in this incident was not an Equinix server but rather customer equipment deployed at one of our Chicago IBX data centers… We generally do not have visibility or control over what our customers – or customers of our customers – do with their equipment.”

Amazon however, do not find the blame to lie on themselves, communicating the following statement:

“Neither AWS nor Amazon Route 53 were hacked or compromised. An upstream Internet Service Provider (ISP) was compromised by a malicious actor who then used that provider to announce a subset of Route 53 IP addresses to other networks with whom this ISP was peered. These peered networks, unaware of this issue, accepted these announcements and incorrectly directed a small percentage of traffic for a single customer’s domain to the malicious copy of that domain.”

Some advice from award winning security blogger, researcher and speaker, Graham Cluley – avoid putting your cryptocurrency wallet online, keep them off your smartphone or computer and perhaps instead invest in a hardware wallet.

Beware: ad slingers thinly disguised as security apps 0 781

Fake Security App

According to AV-Comparatives, an independent testing organization, there are significant differences in the level of protection provided by mobile security solutions. However, even the least secure of them are still far better than questionable apps that impersonate security applications in order to display ads to users. Thirty-five such applications have recently been discovered in the Google Play official Android app store.

These apps have Google Play statistics showing a minimum of over six million installs, cumulatively. However, not all those were necessarily real installations, it is possilbe that many were bot downloads posting fake reviews to improve the ratings for the app.

All 35 apps have been flagged by ESET and eventually removed from the store.

In addition to annoying their victims with ads, disguising these apps as security software has some serious negative side effects, too. In mimicking basic security functions – in fact, they all act as very primitive security checkers relying on a few trivial hardcoded rules – they often detect legitimate apps as malicious. And last but not least, they create a false sense of security in the victims, which might expose them to real risks from malicious apps that are not detected as such.

ESET’s analysis has shown that among these 35 apps, only a handful stand out for their specific features: one app is not completely free as it offers a paid upgrade; one app has implemented a primitive, easily bypassed, app-locker manager; another app flags other apps from this group as dangerous by default; and finally, one misuses ESET’s branding.

 

Security-mimicking functionality
In order to stay under the radar, all the shady ad-displaying apps mimic actual mobile security solutions. However, their ‘detection mechanisms’ are incomplete and very primitive, which makes them easy to bypass and prone to false positives.

Our research into these questionable apps has shown that their ‘detection mechanisms’ can be divided into four categories. These mechanisms are identical or almost identical across the whole set of apps.

1) Package name whitelist & blacklist
These whitelists features popular apps such as Facebook, Instagram, LinkedIn, Skype and others. The ‘blacklists’ contains far too few items to be considered security functionality at all.

2) Permissions blacklist
All apps (including legitimate ones) are flagged if they require some of the listed permissions that are considered dangerous, such as send and receive SMS, access location data, access the camera, etc.

3) Source whitelist
All apps but those from the official Android store, Google Play, are flagged – even if they are completely benign.

4) Activities blacklist
All apps that contain any of the blacklisted activities: that is, parts of applications. This mainly concerns some ad-displaying activities.

Flagged are all apps that contain any of the blacklisted activities, i.e., packages of application that are used in an application. These packages can handle additional functionalities (mainly some ad-displaying activities).

While there is nothing wrong with the idea of activity blacklisting, the implementation in these questionable apps is rather sloppy. For example, Google Ads is included in the blacklist despite the fact that it is a legitimate service. On top of being legitimate, this service is implemented in all of the shady apps we analyzed.

Additional security “functionality”
Some of the questionable security apps are capable of protecting a user’s apps with a password or a pattern locker. The idea behind this seemingly useful feature is to provide the user with another layer of security in selected apps.

However, due to insecure implementation, this feature also fails to provide true security to the user.

The problem is that relevant information is not stored safely on the device – instead of using encryption, which is common baseline practice in cybersecurity, these apps store the names of locked apps and the passwords to unlock them as plaintext.

This means that the data can be accessed after the device is rooted.

Besides compromising the unencrypted data by rooting the phone, there is another way to bypass the app lock. An attacker with physical access to the device can change the app-locking password without knowing the old one!

Conclusion
Having a security solution installed in an Android phone is definitely a good thing. However, not all apps featuring “security” or “antivirus” in their name do what the name promises. Before installing a security solution, think twice: is it really a tool you can safely rely on?

The 35 pseudo-security apps described in this article are not, say, ransomware or other hardcore malware. The only harm they do is displaying annoying ads, making false-positive detections and giving the victim a false sense of security. However, those millions of unwary users who downloaded them could easily have ended up downloading true malware in some similar disguise.

Instead of shady apps with flashy names and icons and outlandish, unsubstantiated promises, seek a reputable security solution. And which one to choose? An independent test by a well-respected testing organization might help.
