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.
Money talks and electronic gaming evolves
Computer gaming has evolved dramatically in the last two years, as it follows the money, writes ARTHUR GOLDSTUCK in the second of a two-part series.
The clue that gaming has become big business in South Africa was delivered by a non-gaming brand. When Comic Con, an American popular culture convention that has become a mecca for comics enthusiasts, was hosted in South Arica for the first time last month, it used gaming as the major drawcard. More than 45 000 people attended.
The event and its attendance was expected to be a major dampener for the annual rAge gaming expo, which took place just weeks later. Instead, rAge saw only a marginal fall in visitor numbers. No less than 34 000 people descended on the Ticketpro Dome for the chaos of cosplay, LAN gaming, virtual reality, board gaming and new video games.
It proved not only that there was room for more than one major gaming event, but also that a massive market exists for the sector in South Africa. And with a large market, one also found numerous gaming niches that either emerged afresh or will keep going over the years. One of these, LAN (for Local Area Network) gaming, which sees hordes of players camping out at the venue for three days to play each other on elaborate computer rigs, was back as strong as ever at rAge.
MWeb provided an 8Gbps line to the expo, to connect all these gamers, and recorded 120TB in downloads and 15Tb in uploads – a total that would have used up the entire country’s bandwidth a few years ago.
“LANs are supposed to be a thing of the past, yet we buck the trend each year,” says Michael James, senior project manager and owner of rAge. “It is more of a spectacle than a simple LAN, so I can understand.”
New phenomena, often associated with the flavour of the moment, also emerge every year.
“Fortnite is a good example this year of how we evolve,” says James. “It’s a crazy huge phenomenon and nobody was servicing the demand from a tournament point of view. So rAge and Xbox created a casual LAN tournament that anyone could enter and win a prize. I think the top 10 people got something each round.”

Blockchain is generally associated with Bitcoin and other cryptocurrencies, but these are just the tip of the iceberg, says ESET Southern Africa.
This technology was originally conceived in 1991, when Stuart Haber and W. Scott Stornetta described their first work on a chain of cryptographically secured blocks, but only gained notoriety in 2008, when it became popular with the arrival of Bitcoin. It is currently gaining demand in other commercial applications and its annual growth is expected to reach 51% by 2022 in numerous markets, such as those of financial institutions and the Internet of Things (IoT), according to MarketWatch.
What is blockchain?
A blockchain is a unique, consensual record that is distributed over multiple network nodes. In the case of cryptocurrencies, think of it as the accounting ledger where each transaction is recorded.
A blockchain transaction is complex and can be difficult to understand if you delve into the inner details of how it works, but the basic idea is simple to follow.
Each block stores:
– A number of valid records or transactions.
– Information referring to that block.
– A link to the previous block and next block through the hash of each block—a unique code that can be thought of as the block’s fingerprint.
Accordingly, each block has a specific and immovable place within the chain, since each block contains information from the hash of the previous block. The entire chain is stored in each network node that makes up the blockchain, so an exact copy of the chain is stored in all network participants.
As new records are created, they are first verified and validated by the network nodes and then added to a new block that is linked to the chain.
How is blockchain so secure?
Being a distributed technology in which each network node stores an exact copy of the chain, the availability of the information is guaranteed at all times. So if an attacker wanted to cause a denial-of-service attack, they would have to annul all network nodes since it only takes one node to be operative for the information to be available.
Besides that, since each record is consensual, and all nodes contain the same information, it is almost impossible to alter it, ensuring its integrity. If an attacker wanted to modify the information in a blockchain, they would have to modify the entire chain in at least 51% of the nodes.
In blockchain, data is distributed across all network nodes. With no central node, all participate equally, storing, and validating all information. It is a very powerful tool for transmitting and storing information in a reliable way; a decentralised model in which the information belongs to us, since we do not need a company to provide the service.
What else can blockchain be used for?
Essentially, blockchain can be used to store any type of information that must be kept intact and remain available in a secure, decentralised and cheaper way than through intermediaries. Moreover, since the information stored is encrypted, its confidentiality can be guaranteed, as only those who have the encryption key can access it.
Use of blockchain in healthcare
Health records could be consolidated and stored in blockchain, for instance. This would mean that the medical history of each patient would be safe and, at the same time, available to each doctor authorised, regardless of the health centre where the patient was treated. Even the pharmaceutical industry could use this technology to verify medicines and prevent counterfeiting.
Use of blockchain for documents
Blockchain would also be very useful for managing digital assets and documentation. Up to now, the problem with digital is that everything is easy to copy, but Blockchain allows you to record purchases, deeds, documents, or any other type of online asset without them being falsified.
Other blockchain uses
This technology could also revolutionise the Internet of Things (IoT) market where the challenge lies in the millions of devices connected to the internet that must be managed by the supplier companies. In a few years’ time, the centralised model won’t be able to support so many devices, not to mention the fact that many of these are not secure enough. With blockchain, devices can communicate through the network directly, safely, and reliably with no need for intermediaries.
Blockchain allows you to verify, validate, track, and store all types of information, from digital certificates, democratic voting systems, logistics and messaging services, to intelligent contracts and, of course, money and financial transactions.
Without doubt, blockchain has turned the immutable and decentralized layer the internet has always dreamed about into a reality. This technology takes reliance out of the equation and replaces it with mathematical fact.
