Trojan invades Android brains

Kaspersky Lab has detected Triada, a Trojan targeting Android devices that can be accidentally downloaded by installing untested applications from the Google Play Store.

According to the recent Kaspersky Lab research on Mobile Virusology, nearly half of the top 20 Trojans in 2015 were malicious programmes with the ability to gain super-user access rights. Super-user privileges give cybercriminals the rights to install applications on the phone without the user’s knowledge.

This type of malware propagates through applications that users download/install from untrusted sources. These apps can sometimes be found in the official Google Play app store, masquerading as a game or entertainment application. They can also be installed during an update of existing popular applications and, are occasionally pre-installed on the mobile device. Those at greatest risk include devices running 4.4.4. and earlier versions of the Android OS.

There are 11 known mobile Trojan families that use root privileges. Three of them – Ztorg, Gorpo and Leech – act in cooperation with each other. Devices infected with these Trojans usually organise themselves into a network, creating a sort of advertising botnet that threat actors can use to install different kinds of adware.

Shortly after rooting on the device, the above-mentioned Trojans download and install a backdoor. This then downloads and activates two modules that have the ability to download, install and launch applications.

The application loader and its installation modules refer to different types of Trojans, but all of them have been added to our antivirus databases under a common name – Triada.

A distinguishing feature of this malware is the use of Zygote – the parent of the application process on an Android device – that contains system libraries and frameworks used by every application installed on the device. In other words, it’s a demon whose purpose is to launch Android applications. This is a standard app process that works for every newly installed application. It means that as soon as the Trojan gets into the system, it becomes part of the app process and will be pre-installed into any application launching on the device and can even change the logic of the application’s operations.

This is the first time technology like this has been seen in the wild.

The stealth capabilities of this malware are very advanced. After getting into the user’s device Triada implements in nearly every working process and continues to exist in the short-term memory. This makes it almost impossible to detect and delete using antimalware solutions. Triada operates silently, meaning that all malicious activities are hidden both from the user and from other applications.

The complexity of the Triada Trojan’s functionality proves the fact that very professional cybercriminals, with a deep understanding of the targeted mobile platform, are behind this malware.

The Triada Trojan can modify outgoing SMS messages sent by other applications. This is now a major functionality of the malware. When a user is making in-app purchases via SMS for Android games, fraudsters are likely to modify the outgoing SMS so that they receive the money instead of the game developers.

“The Triada of Ztrog, Gorpo and Leech marks a new stage in the evolution of Android-based threats. They are the first widespread malware with the potential to escalate their privileges on most devices. The majority of users attacked by the Trojans were located in Russia, India and Ukraine as well as APAC countries. It is hard to underestimate the threat of a malicious application gaining root access to a device. Their main threat, as the example of Triada shows, is in the fact that they provide access to the device for much more advanced and dangerous malicious applications. They also have a well-thought-out architecture developed by cybercriminals who have deep knowledge of the target mobile platform,” said Nikita Buchka, Junior Malware Analyst, Kaspersky Lab.

As it is nearly impossible to uninstall this malware from a device, users face two options to get rid of it. The first is to “root” their device and delete the malicious applications manually. The second option is to jailbreak the Android system on the device.

Kaspersky Lab products detect Triada Trojan components as: Trojan-Downloader.AndroidOS.Triada.a; Trojan-SMS.AndroidOS.Triada.a; Trojan-Banker.AndroidOS.Triada.a; Backdoor.AndroidOS.Triada.

Mobile is the new branch

Standard Bank has launched an account for mobile devices that gives back 500MB of data a month

Standard Bank has introducd a R4.95p/m bank account called MyMo that customers can open on their mobile devices, loaded with data and airtime offerings and other benefits such as virtual and Gold physical card.

MyMo account holders will also enjoy the convenience of a cheque account through a Visa and Mastercard gold card. Once the account is open, users can choose to either receive R50 in airtime or 500MB of data a month, if their card is swiped more than four times a month. A further megabyte of data is loaded on the account for every R20 spent.

“MyMo is an account for everyone, whether you just landed your first job or have been around the block. With no documentation required it only takes a few minutes to open the account,” says Funeka Montjane, Chief Executive for Personal and Business Banking, South Africa, at Standard Bank Group. “For just R4.95 a month customer will be able to enjoy free swipes and ATM withdrawals at only R6.50 for amounts under R 1 000.

“Mobile is the new branch. This account is about bringing the mobile branch into customers hands, it is about convenience and security while banking.”

She says mobile offers low cost transactional banking which integrates people and businesses into the new connected economy, making mobile the new branch ecosystem that will drive and connect Africa’s growth. Physical connections to the economy are rapidly changing to digital where banks have to move from being financial institutions to service organisations.

“In the past people congregated in communities and eventually cities to maximise the advantages of connectivity. Today a simple hand-held device has the potential to open infinite doors, transforming individuals’ access to opportunities, regardless of where they are, and like never before in history. 

“Historically, a bank account represented access to economic citizenship. Today, having a simple device enabling digital access to a modern banking platform is a passport to global connectivity and vast human development potential.”

The bank says it is using technology, and mobile phones in particular, to deliver low-cost transactional channels accessible to all our customers. The evolution in mobile can be seen in transaction options like cash back at the retail checkout till rather than the ATM, free digital banking rather than using a branch, and the ability to transact using digital wallets, even without a bank account.

“Developing comprehensive connected ecosystems requires a mind-set change from Africa’s banks,” says Montjane. “Banks will evolve away from traditional financial service organisations, into service ecosystems enabling broad universal access to almost everything like enhanced purchasing experiences of vehicles and homes, online procurement of goods and services and lifestyle elements like rewards and travel. 

“These connectivity drivers will also act to future-proof evolving connectivity ecosystem by allowing us to offer untold future services while deriving income from as yet unrealised revenue streams,.   

From a customer perspective, the kind of ecosystems of knowledge, access and, ultimately, connectivity that banks will come to provide will radically transform the share of life that almost all individuals will be able to access.”

Two-thirds of SA staff hide social media from bosses

With 90% of people in employment going online several times a day, it can be hard for most workers to keep their private and work-life separate during the working day (and beyond). The recently published Global Privacy Report from Kaspersky Lab reveals that 64% of South African consumers choose to hide social media activity from their boss. This secretive stance at work also extends to their colleagues, with 60% of South Africans also preferring not to reveal online activities to their co-workers.

Globally, the average employee spends an astonishing 13 years and two months at work during their lifetime. Interestingly though, not all this time is directly related to solving work tasks or earning a promotion: almost two thirds (64%) of consumers admit visiting non-work-related websites every day from their desk.

Not surprisingly, 35% of South African employees are against their employer knowing which websites they visit. However, more interestingly, 60% of South African are even against their colleagues knowing about their online activities. This probably means that colleagues constitute an even greater threat to future perspectives of an office slouch or maybe the relationships with colleagues are more informal and therefore, more valuable.

On the contrary, social media activity appears to be a less private domain for many and therefore, more suitable for sharing with colleagues but not the boss. This is probably because workers fear harming the public image of a company or interest in decreased staff productivity motivates companies to monitor employees’ social networks and make career changing decisions based on that. Such policies have led to 64% of South Africans saying that they don’t want to reveal their social media activities to their boss and 53% even don’t want to disclose this information to their colleagues.

A further 29% are against showing the content of their messages and emails to their employer. In addition, 3% even said that their career was irrevocably damaged as a consequence of their personal information being leaked. Thus, people are worried about how to build a favourable internal reputation and how not to destroy existing workplace relationships.

“As going online is an integral part of our life nowadays, lines continue to blur between our digital existence at work and at home. And that’s neither good nor bad. That’s how we live in the digital age. Just keep remembering that as an employee you need to be increasingly cautious of what exactly you post on social media feeds or what websites you prefer using at work. One misconceived action on the internet could have an irrevocable long-term impact on even the most ambitious worker’s ability to climb the career ladder of their choice in the future,” comments Marina Titova, Head of Consumer Product Marketing at Kaspersky Lab.

To ensure workers don’t fall prey of the internet threats at a work, there are some core guidelines to adhere to in the digital age:

  • Don’t post anything that could be considered defamatory, obscene, proprietary or libellous. If in doubt, don’t post.
  • Be aware that system administrators may at least, in theory, be informed about your web browsing patterns.
  • Don’t harass, threaten, discriminate or disparage against any colleague, partner, competitor or customer. Neither on social networks or in messages, emails, nor by any other means.
  • Don’t post photographs of other employees, customers, vendors, suppliers or company products without prior written permission.
  • Start using Kaspersky Password Manager to ensure your social media and other personal accounts are not at risk of unauthorised access by someone else in an office. Install a reliable security solution such as Kaspersky Security Cloud to protect your personal devices.
