Kaspersky Lab has discovered ‘Slingshot’ malware which attacks and infects victims through compromised routers and can run in kernel mode, giving it complete control over victim devices.
Kaspersky Lab researchers have uncovered a sophisticated threat used for cyber-espionage in the Middle East and Africa from at least 2012 until February 2018. The malware, which researchers have called ‘Slingshot’, attacks and infects victims through compromised routers and can run in kernel mode, giving it complete control over victim devices. According to researchers, many of the techniques used by this threat actor are unique and it is extremely effective at stealthy information gathering, hiding its traffic in marked data packets that it can intercept without trace from everyday communications.
The Slingshot operation was discovered after researchers found a suspicious keylogger program and created a behavioural detection signature to see if that code appeared anywhere else. This triggered a detection that turned out to be an infected computer with a suspicious file inside the system folder named scesrv.dll. The researchers decided to investigate this further. Analysis of the file showed that despite appearing legitimate, the scesrv.dll module had malicious code embedded into it. Since this library is loaded by ‘services.exe’, a process that has system privileges, the poisoned library gained the same rights. The researchers realised that a highly advanced intruder had found its way into the very core of the computer.
The most remarkable thing about Slingshot is probably its unusual attack vector. As researchers uncovered more victims, they found that many seemed to have been initially infected through hacked routers. During these attacks, the group behind Slingshot appears to compromise the routers and place a malicious dynamic link library inside it that is in fact a downloader for other malicious components. When an administrator logs in to configure the router, the router’s management software downloads and runs the malicious module on the administrator’s computer. The method used to hack the routers in the first place remains unknown.
Following infection, Slingshot loads a number of modules onto the victim device, including two huge and powerful ones: Cahnadr, and GollumApp. The two modules are connected and able to support each other in information gathering, persistence and data exfiltration.
Slingshot’s main purpose seems to be cyberespionage. Analysis suggests it collects screenshots, keyboard data, network data, passwords, USB connections, other desktop activity, clipboard data and more, although its kernel access means it can steal whatever it wants.
The advanced, persistent threat also incorporates a number of techniques to help it evade detection: including encrypting all strings in its modules, calling system services directly in order to bypass security-product hooks, using a number of Anti-debugging techniques, and selecting which process to inject depending on the installed and running security solution processes, and more.
Slingshot works as a passive backdoor: it does not have a hardcoded command and control (C&C) address but obtains it from the operator by intercepting all network packages in kernel mode and checking to see if there are two hardcoded magic constants in the header. If this is the case, it means that that package contains the C&C address. After that, Slingshot establishes an encrypted communication channel to the C&C and starts to transmit data for exfiltration over it.
The malicious samples investigated by the researchers were marked as ‘version 6.x’, which suggests the threat has existed for a considerable length of time. The development time, skill and cost involved in creating Slingshot’s complex toolset is likely to have been extremely high. Taken together, these clues suggest that the group behind Slingshot is likely to be highly organised and professional and probably state-sponsored. Text clues in the code suggest it is English-speaking. However, accurate attribution is always hard, if not impossible to determine, and increasingly prone to manipulation and error.
So far, researchers have seen around 100 victims of Slingshot and its related modules, located in Kenya, Yemen, Afghanistan, Libya, Congo, Jordan, Turkey, Iraq, Sudan, Somalia and Tanzania. Most of the victims appear to be targeted individuals rather than organisations, but there are some government organisations and institutions. Kenya and the Yemen account for most of the victims observed so far.
“Slingshot is a sophisticated threat, employing a wide range of tools and techniques, including kernel mode modules that have to date only been seen in the most advanced predators. The functionality is very precious and profitable for the attackers, which could explain why it has been around for at least six years,” said Alexey Shulmin, Lead Malware Analyst, Kaspersky Lab.
All Kaspersky Lab products successfully detect and block this threat.
To avoid falling victim to such an attack, Kaspersky Lab researchers recommend implementing the following measures:
- Users of Mikrotik routers should upgrade to the latest software version as soon as possible to ensure protection against known vulnerabilities. Further, Mikrotik Winbox no longer downloads anything from the router to the user’s computer.
- Use a proven corporate grade security solution in combination with anti-targeted attack technologies and threat intelligence, like Kaspersky Threat Management and Defense solution. These are capable of spotting and catching advanced targeted attacks by analysing network anomalies and give cybersecurity teams full visibility over the network and response automation;
- Provide security staff with access to the latest threat intelligence data, which will arm them with helpful tools for targeted attack research and prevention, such as indicators of compromise (IOC), YARA and customised advanced threat reporting;
- If you spot early indicators of a targeted attack, consider managed protection services that will allow you to proactively detect advanced threats, reduce dwell time and arrange timely incident response.
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.
