Fake Korean bank applications for Android – PT 1

About a year ago, we published this analysis about a pharming attack against Korean bank customers. The banks targeted by cybercriminals included NH Bank, Kookmin Bank, Hana Bank, ShinHan Bank, and Woori Bank. With the rise of Android-powered devices, these attacks now occur not only on the Windows platform, but also on the Android platform. In this blogpost we will look at a fake bank application and analyze several malware families which supposedly utilize them.

Original bank application

We will show just one bank application for brevity. For other banks the scenario is similar. The real Hana Bank application can be downloaded from Google Play. It has the following layout and background.

How are you doing Mr. Android?

First of all, I would like to shift your attention a bit backwards. No worries! This is not a history lesson or something from the ancient past.  Rather, I would like to share with you folks some Android statistics from the last two years. Hopefully, it will give you a better idea about which malware is spread around the most. By the way, if growth of Android malware was on the stock exchange and you had invested some money in it, you would have become a billionaire a few months ago. So let’s check out some graphs!

cumulative samples 2

In the first graph you can see how many samples we have to process in our databases. It shows dates between 2010 through the end of 2013. Pretty nice growth, isn’t it? By the end of 2013, we had almost 800,000 unique suspicious Android samples which we had to process and cover in VPS updates.

detections

In the second graph, you can see the TOP 10 detections of malware families we have seen during the last half of the year. The majority are fake applications or data stealing apps. This group of malware can really easily mess up your device. Data which is mined from these apps can be used against you. Last year, I blogged about a few examples which we saw infecting devices – but that was just a piece of a bigger pie.

What might be strange in the second graph is that four of the top ten have something to do with SMS sending. That means they are able to steal your money using SMS messages. That’s probably the most common way for mobile cybercrooks to quickly steal money. For malware programmers, it is really easy to access those parts in devices and send premium messages.

I hope that even skeptics will agree that protecting your device from malware threats is necessary these days. :) Try avast! Mobile Security for free.

What bugged AVAST users this year: Mobile malware and fraud

Last year, on Christmas day, over 17 million new mobile devices went online. Before the ribbons and wrapping paper could be discarded, cybercrooks started their attacks.
santa-with-mobile

In the first half of this year, experts said that 79 percent of all mobile malware attacks were on Android systems. When we asked Ondrej Vlček, AVAST’s Chief Technology Officer, about mobile security in 2013 and what we can expect in 2014, he answered, “Mobile threats will certainly continue to be on the rise. We see nearly 2,000 new malware samples on Android every day, and this is up from maybe 50 a year ago. It’s quite likely that the trend will continue. Especially if you are running an Android device, you absolutely need to install a security product.”

Online fraud goes viral on mobile

Paving the way for a mobile-payment driven future like Japan and Singapore have developed, mobile phones morphed into wallets during 2013, including SMS, WAP and near-field communications (NFC) payment. Data privacy and security have emerged as critical issues over the past few years, and will continue to be important as these new mobile payment options introduce new threats of data hacking and fraud.

AVAST detected an average of 1,839 new mobile malware samples a day, about 60 to 70% of which were designed to send and charge mobile users for premium SMS.

Speaking to SC Magazine about mobile malware, Vlček said, “Especially on Android, the KPIs are exploding, because its openness and design make it a logical choice for the attacker, and it has reached a critical mass in terms of penetration and market share.”  And, he adds, with the smartphone’s ability to send premium SMS and spam SMS messages offering new channels for malware writers to make money, it’s only going to get worse.

AVAST this year has also seen more targeted attacks where the goal is to steal users‘ financial transaction data and ultimately their money. This includes hacking specific banks by manipulating their Internet banking interfaces to steal the customer’s personal data.

On the road with avast! Mobile Security

With six fewer days between Thanksgiving and Christmas this year, the highways are already busy with tractor trailers delivering merchandise to retailers, shoppers making gift runs, and families hitting the road or airports to travel “Over the River and Through the Woods” to Grandmother’s house. With all that moving around, it’s a given that someone will lose their smartphone or tablet.

truckers
In fact, “One hundred thirteen smartphones are lost or stolen every minute in the US,” said Stephen Ebbett, president of lifestyle insurance company, Protect Your Bubble, in an interview on Fox Techtake. In a survey conducted by the company earlier this year, they discovered that people are most likely to lose their phones when traveling. Twenty-three percent of cell phones are left at the airport, 21.7% are left at hotels, 18% are lost or stolen on public transportation,  or forgotten in a rental car (11.5%).

The need to protect truck drivers smartphones

Truck drivers are among those professional travelers whose devices have been lost or stolen. It’s an important subject for drivers because bring-your-own-device is being adopted by many trucking companies. Stephen Bennett of Transport Topics, The Newspaper of Trucking and Freight Transportation, wrote about it in the Oct-Nov issue,

…security features…available from companies that cater to consumers are becoming increasingly important to over-the-road truck drivers because of a trend that has been described as the “consumerization” of business technology or “BYOD” — tech-talk for “bring your own device.”

Bennett spoke to Juraj Chrappa, senior product manager of avast! Mobile Security. Chrappa said that an AVAST survey conducted in June indicated that 25% of AVAST users, or more than 6 million people with mobile devices, had lost their devices or they had been stolen with U.S. consumers among those most likely to lose or have their phone stolen.The average cost of a smart phone is $372, he added.

Beware of poisoned apples

loginEverybody knows the story of the beautiful Snow White. An evil queen with a bad temper gives a young girl a poisoned apple, because she apparently thinks that it would just make her day. Poor Snow White. All she wanted was a bite of this juicy apple. I guess this one particular bite didn’t make her very happy. Anyway, she apparently made some mistakes, that I can tell. For example, if she wanted an apple, she should have just picked one from a “genuine” tree. Or she could have had someone taste the apple first, like a brave knight that’s always there for her, protecting her every second.

Yes, it’s been a while since that famous apple incident happened. Nowadays, a girl wouldn’t just accept an apple from a stranger and take a bite right away. She would at least wash it first! If she’s smart enough, she’s going to have something that tells her more about the apple.

With the magic of fairy dust and special effects, let’s transform this story into the world of mobile security.

Poisoned APPles

The Snow White fairy tale came to life a few days ago, when we found a fake Apple iMessage app for Android. There are lot of apps for Apple iOS that are not released for other platforms. For example, when two people have an iPhone, they can send each other messages for free via Apple’s iMessage service. The Android alternative for that service would probably be Google’s Hangouts app. The problem occurs when you want to send a free text message from iOS to Android. Yes, there’s WhatsApp, Viber, and similar apps, but there’s no way to send an iMessage to Android, nor iMessage from Android. That problem seems to bother some people, so they are eagerly waiting for a solution. The evil queen is aware of the need, so she makes poisoned apples and hands them out for free, telling others that they are sweet, juicy, and absolutely free from poison. Yes, I’m talking about fake apps that are trying to look like official Apple apps for Android. Read more…

Fake Antivirus Android application discovered

AVAST virus lab analyst Filip Chytrý has discovered a fake Android Antivirus application impersonating avast! Free Mobile Security.  The malicious application called com.avastmenow has a user interface that looks very similar to the genuine one by AVAST Software. After the installation of the fake program, an icon with the text of PornHub is displayed to users.  The Trojan displays fake alert pop ups in an attempt to convince the user he is infected even when he is not. Users who download the fake application might end up with their Smartphone device blocked and be requested to pay 100$ to unlock the phone.

Our virus lab specialists are currently working on samples, so the AVAST virus database will be updated shortly. The goal is to protect all avast! Antivirus users and prevent them from downloading the malicious application. We will update our community on the progress here and on our social media channels.

Meanwhile we recommend all users to use trusted source and download avast! free Mobile Security only from here.

avast! Mobile Security trusted by millions to fight Android malware

50m_en

There have been over 50 million downloads of avast! Mobile Security from Google Play since it was released last year. Android users are becoming more aware of the security and theft issues surrounding their mobile devices, and putting their trust in AVAST. A few weeks ago, avast! Mobile Premium was introduced providing superior back-up and anti-theft technology.

Android is the world’s most widely used mobile operating system (OS). That popularity, together with its open source architecture, makes it a primary target for malware attacks. Android threats make up 79 percent of all known mobile malware, so mobile security should no longer be considered optional.

The avast! Mobile Security Virus Scanner detected 99% of malware with no false positives in a recent test by independent lab AV-Comparatives. That exemplary detection plus the fact that avast! Mobile Security has negligible impact on your smartphone’s performance or battery life, is why we have had 50 million downloads.
