BRENDAN MCARAVEY, Country Manager, Citrix South Africa, takes a look at what Cryptojacking jacking is, how it works and how it can be avoided.
Parasites in the digital world don’t kill, encrypt, or ransom the hosts as compared to the parasites in the real world. However, they do siphon off compute resources – preferably undetected. Compute resources are a valuable commodity in the world of crypto-mining. This stealthier malware phenomenon called ‘cryptojacking’ is becoming a popular payload since it’s an effective way to generate revenue with a lower chance of detection. The goal is to run undetected – stealing CPU cycles – essentially becoming a digital parasite.
Crafty adversaries driven by the opportunity of financial gain are weaponising crypto-mining to exploit the digital currency boom. Before we go any further, it is key to understand what ‘crypto-mining’ is? It is an intensive process – consistently running mathematical calculations that keep processors at 100% usage.
Professional miners make a large upfront investment in specialised hardware and infrastructure. Case in point, according to a South African gaming website, since the cryptocurrency boom, it has become extremely hard to get hands on graphics cards. They are mostly out of stock, with no guarantee on when they will be back in stock and sky-high prices are being asked for second-hand cards in local classifieds.
As more miners came online, the difficulty level adjusted so that running multiple graphics processing units (GPUs) became more effective at mining. Next came specialised chipsets or ASICs designed specifically for mining Bitcoin – these are getting smaller and more efficient. To increase the chances of pay-out, multiple miners join pools in which they are compensated based on their contribution of compute resources or hash power.
A tell-tale symptom of your CPU being used by miners is sluggishness, high CPU usage, and the whine of maxed-out RPM on the cooling fans. Cryptojacking is not just limited to laptops and PCs, mobile devices and gadgets are also susceptible, even more so since the mining scripts can run in the background or are more difficult to identify.
As with other attacks, server side cryptojacking can be more complex and more complicated once it spreads. If the attacker gets access to the infrastructure, he or she may provision additional servers – in cloud environments, expect to see new servers with high end specs and cost.
Locally we haven’t as yet witnessed cryptojacking attacks, however, globally an example is WannaMine, where the attackers use ‘live off the land’ technique such as Windows Management Instrumentation (WMI) permanent event subscriptions as a persistence mechanism. It also propagates via the EternalBlue exploit popularised by WannaCry.
It’s fileless nature and use of legitimate system software such as WMI and PowerShell make it difficult, if not impossible, for organisations to block it without some form of next-generation antivirus. Defending against cryptojacking requires a holistic approach and building a security architecture with a secure digital perimeter. The approach must focus on prevention as well as detection. Citrix has partnered with multiple security companies that enhance endpoint, network, server, and cloud protection.
For enterprises, delivering a locked down Secure Browser as a service can help reduce the attack surface by blocking the mining scripts as well as blocking the periodic call-backs to the mining pools – which are the command and control for crypto mining.
A critical component is early detection of CPU spikes above normal range – typically sustained. IT Operations should have defined CPU thresholds and analytics with alerts sent to admins when the CPU usage rises above the threshold. A couple of side notes here are that the alerts should disregard the process names – the digital parasite wants to remain undetected and can be disguised to be a system service or process.
Secondly, more devious adversaries will tune down the CPU leeching to not stand out as dramatically – effectively flying under the radar. Establishing a baseline and identifying aberrations quickly is the goal. Once detected, restoring the server to a golden image makes the process easier – local backdoor accounts, services, other changes can be undone.
Protecting against cryptojacking is very much the same as protecting against other malware – however, we are looking for different symptoms and long-term effects in hardware wear and tear, user performance degradation and loss of scalability. Higher costs in electricity or cloud usage are both more intermediate financial symptoms. Stay vigilant even if there are no demand notes or immediate indicators of compromise.
IoT sensors are anything from doctor to canary in mines
Industrial IoT is changing the shape of the mining industry and the intelligence of the devices that drive it
The Internet of Things (IoT) has become many things in the mining industry. A canary that uses sensors to monitor underground air quality, a medic that monitors healthcare, a security guard that’s constantly on guard, and underground mobile vehicle control. It has evolved from the simple connectivity of essential sensors to devices into an ecosystem of indispensable tools and solutions that redefine how mining manages people, productivity and compliance. According to Karien Bornheim, CEO of Footprint Africa Business Solutions (FABS), IoT offers an integrated business solution that can deliver long-term, strategic benefits to the mining industry.
“To fully harness the business potential of IoT, the mining sector has to understand precisely how it can add value,” she adds. “IoT needs to be implemented across the entire value chain in order to deliver fully optimised, relevant and turnkey operational solutions. It doesn’t matter how large the project is, or how complex, what matters is that it is done in line with business strategy and with a clear focus.”
Over the past few years, mining organisations have deployed emerging technologies to help bolster flagging profits, manage increasingly weighty compliance requirements, and reduce overheads. These technologies are finding a foothold in an industry that faces far more complexities around employee wellbeing and safety than many others, and that juggles numerous moving parts to achieve output and performance on a par with competitive standards. Already, these technologies have allowed mines to fundamentally change worker safety protocols and improve working conditions. They have also provided mining companies with the ability to embed solutions into legacy platforms, allowing for sensors and IoT to pull them into a connected net that delivers results.
“The key to achieving results with any IoT or technology project is to partner with service providers, not just shove solutions into identified gaps,” says Bornheim. “You need to start in the conceptual stage and move through the pre-feasibility and bankable feasibility stages before you start the implementation. Work with trained and qualified chemical, metallurgical, mechanical, electrical, instrumentation and structural engineers that form a team led by a qualified engineering lead with experience in project management. This is the only way to ensure that every aspect of the project is aligned with the industry and its highly demanding specifications.”
Mining not only has complexities in compliance and health and safety, but the market has become saturated, difficult and mercurial. For organisations to thrive, they must find new revenue streams and innovate the ways in which they do business. This is where the data delivered by IoT sensors and devices can really transform the bottom line. If translated, analysed and used correctly, the data can provide insights that allow for the executive to make informed decisions about sites, investment and potential.
“The cross-pollination of different data sets from across different sites can help shift dynamics in plant operation and maintenance, in the execution of specific tasks, and so much more,” says Bornheim. “In addition, with sensors and connected devices and systems, mining operations can be managed intelligently to ensure the best results from equipment and people.”
The connection of the physical world to the digital is not new. Many of the applications currently being used or presented to the mining industry are not new either. What’s new is how these solutions are being implemented and the ways in which they are defined. It’s more than sticking on sensors. It’s using these sensors to streamline business across buildings, roads, vehicles, equipment, and sites. These sensors and the ways in which they are used or where they are installed can be customised to suit specific business requirements.
“With qualified electronic engineers and software experts, you can design a vast array of solutions to meet the real needs of your business,” says Bornheim. “Our engineers can programme, create, migrate and integrate embedded IoT solutions for microcontrollers, sensors, and processors. They can also develop intuitive dashboards and human-machine interfaces for IoT and machine-to-machine (M2M) devices to manage the input and output of a wide range of functionalities.”
The benefits of IoT lie in its ubiquity. It can be used in tandem with artificial intelligence or machine learning systems to enhance analytics, improve the automation of basic processes and monitor systems and equipment for faults. It can be used alongside M2M applications to enhance the results and the outcomes of the systems and their roles. And it can be used to improve collaboration and communication between man, machine and mine.
“You can use IoT platforms to visualise mission-critical data for device monitoring, remote control, alerts, security management, health and safety and healthcare,” concludes Bornheim. “The sky is genuinely the limit, especially now that the cost of sensors has come down and the intelligence of solutions and applications has gone up. From real-time insights to hands-on security and safety alerts to data that changes business direction and focus, IoT brings a myriad of benefits to the table.”
