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.
Legion gets a pro makeover
Lenovo’s latest Legion gaming laptop, the Y530, pulls out all the stops to deliver a sleek looking computer at a lower price point, writes BRYAN TURNER
Gaming laptops have become synonymous with thick bodies, loud fans, and rainbow lights. Lenovo’s latest gaming laptop is here to change that.
The unit we reviewed housed an Intel Core i7-8750H, with an Nvidia GeForce GTX 1060 GPU. It featured dual storage, one bay fitted with a Samsung 256GB NVMe SSD and the other with a 1TB HDD.
The latest addition to the Legion lineup has become far more professional-looking, compared to the previous generation Y520. This trend is becoming more prevalent in the gaming laptop market and appeals to those who want to use a single device for work and play. Instead of sporting flashy colours, Lenovo has opted for an all-black computer body and a monochromatic, white light scheme.
The laptop features an all-metal body with sharp edges and comes in at just under 24mm thick. Lenovo opted to make the Y530’s screen lid a little shorter than the bottom half of the laptop, which allowed for more goodies to be packed in the unit while still keeping it thin. The lid of the laptop features Legion branding that’s subtly engraved in the metal and aligned to the side. It also features a white light in the O of Legion that glows when the computer is in use.
The extra bit of the laptop body facilitates better cooling. Lenovo has upgraded its Legion fan system from the previous generation. For passive cooling, a type of cooling that relies on the body’s build instead of the fans, it handles regular office use without starting up the fans. A gaming laptop with good passive cooling is rare to find and Lenovo has shown that it can be achieved with a good build.
The internal fans start when gaming, as one would expect. They are about as loud as other gaming laptops, but this won’t be a problem for gamers who use headsets.

Serious about security? Time to talk ISO 20000
By EDWARD CARBUTT, executive director at Marval Africa
The looming Protection of Personal Information (PoPI) Act in South Africa and the introduction of the General Data Protection Regulation (GDPR) in the European Union (EU) have brought information security to the fore for many organisations. This in addition to the ISO 27001 standard that needs to be adhered to in order to assist the protection of information has caused organisations to scramble and ensure their information security measures are in line with regulatory requirements.
However, few businesses know or realise that if they are already ISO 20000 certified and follow Information Technology Infrastructure Library’s (ITIL) best practices they are effectively positioning themselves with other regulatory standards such as ISO 27001. In doing so, organisations are able to decrease the effort and time taken to adhere to the policies of this security standard.
ISO 20000, ITSM and ITIL – Where does ISO 27001 fit in?
ISO 20000 is the international standard for IT service management (ITSM) and reflects a business’s ability to adhere to best practice guidelines contained within the ITIL frameworks.
ISO 20000 is process-based, it tackles many of the same topics as ISO 27001, such as incident management, problem management, change control and risk management. It’s therefore clear that if security forms part of ITSM’s outcomes, it should already be taken care of… So, why aren’t more businesses looking towards ISO 20000 to assist them in becoming ISO 27001 compliant?
The link to information security compliance
Information security management is a process that runs across the ITIL service life cycle interacting with all other processes in the framework. It is one of the key aspects of the ‘warranty of the service’, managed within the Service Level Agreement (SLA). The focus is ensuring that the quality of services produces the desired business value.
So, how are these standards different?
Even though ISO 20000 and ISO 27001 have many similarities and elements in common, there are still many differences. Organisations should take cognisance that ISO 20000 considers risk as one of the building elements of ITSM, but the standard is still service-based. Conversely, ISO 27001 is completely risk management-based and has risk management at its foundation whereas ISO 20000 encompasses much more
Why ISO 20000?
Organisations should ask themselves how they will derive value from ISO 20000. In Short, the ISO 20000 certification gives ITIL ‘teeth’. ITIL is not prescriptive, it is difficult to maintain momentum without adequate governance controls, however – ISO 20000 is. ITIL does not insist on continual service improvement – ISO 20000 does. In addition, ITIL does not insist on evidence to prove quality and progress – ISO 20000 does. ITIL is not being demanded by business – governance controls, auditability & agility are. This certification verifies an organisation’s ability to deliver ITSM within ITIL standards.
Ensuring ISO 20000 compliance provides peace of mind and shortens the journey to achieving other certifications, such as ISO 27001 compliance.
