Threat hunters emerge from the shadows

Published

on

As a new generation of cyber threats emerges, a new breed of cyber security defenders is emerging. They don’t wait for enemies to strike, but go looking for them, writes ARTHUR GOLDSTUCK.

Meet Alex and Andy. They are young, clean-cut and casually dressed men who may not draw a second glance if you bump into them in public. Behind closed doors, however, they are the information age’s equivalent of fearsome warriors. They are called threat hunters.

No, they are not super-heroes. Although they are heroes to some organisations.

Five years ago, the job description didn’t even exist. Back then, security experts waited for the hackers to strike, then rushed around repairing the damage, fixing the holes and, just maybe, chasing down the bad guys.

But that’s not good enough today. As hackers become more sophisticated in both their methods and their tools, and the stakes get higher in lost data and massive financial fraud, the security industry also has to evolve.

Alex and Andy represent the cutting edge of this evolution. In an age of heavy reliance on algorithms and artificial intelligence to predict and block standard threats, it turns out that human intuition is far more powerful in spotting unusual and new kinds of attack.

They work in Johannesburg for a global cyber security consultancy called MWR InfoSecurity, which develops tailored security solutiosn for clients that range from governments to corporations.

Their boss, Jacques Louw, MWR director and head of Cyber Defence, describes threat hunting as a technique that “focuses on the human elements in attack detection”. In this environment, he says, “one cannot have automated threat hunting”.

He uses the evolution of physical home security as an analogy for the growing need for a new kind of approach.

“We’ve seen in the last decade or so that, ultimately, you cannot prevent attackers from climbing over your walls no matter how high you build them; they always seem to find a higher ladder. So the focus has really been towards detection and response for when they do manage to get over. In this regard, detection is critical – if you don’t see the intruder, then the armed response never arrives, whereas if you have too many false alarms, the armed response will stop showing up.”

Add the fact that organised crime syndicates are now targeting major corporations, and state sponsored teams are going after national governments, the challenge becomes even more complex. Enter a new kind of detection.

“Detecting attacks is not a new idea,” says Louw. “In fact it’s been around for many years, comprising automated systems like anti-virus and intrusion detection or prevention systems. Think of them as anti-virus for a network traffic.

“Such systems were originally built to deal with viruses or malicious software or malware that was self-propagating – which means it spreads on its own in an automated way. After the malware is created, it acts automatically, executing the tasks it was initially programmed to do.

“Traditional anti-virus works by analysing a piece of malware, creating a signature for it and adding it to a database – similar to that of a book of criminal records. The anti-virus then checks each new program on a system against these records, and alerts you when it finds one with features similar to that of one of the records.

“Unfortunately, the first problem here is that you need to discover a piece of malware before you can create a signature for it, so it has to succeed in attacking someone first before a signature can exist. Moreover, it is quite easy for a programmer to change what the malware looks like – while still having the malware do the same thing. So changing features, but not behaviour.”

A key reason traditional security is no longer enough is that the threat has evolved from the equivalent of a property invasion to something far more elaborate.

Louw compares a modern corporate network to a large city, with multiple roads in and out and many thousands of everyday people performing many different activities across the city.

“In this analogy, a signature-based system is similar to a simplistic robot that walks around the city, trying to match faces of people he sees to a photo in the mugshot book. In contrast, threat hunting is like a human policeman that can actually spot bad behaviour, not because each bad activity has been strictly defined and given to him on a long list, but rather because he can use his experience, knowledge of the law and judgement to make a call on some behaviour that has never been seen before.”

An example is a form of malware that operates not like a virus spreading through the system, but like a hole in the system. Appropriately called RATS, for Remote Access Trojans, these are “exploits” that can easily be altered slightly to bypass anti-virus every time they are used.

“The attacker only needs to find a single entry-point to compromise an organisation, so the defender must defend all systems perfectly all the time to be secure,” says Louw. This concept is known in security as “the defender’s dilemma”

“In threat hunting, one of the ways we are responding to this dilemma is by using a judo-like technique called the anomaly analysis, where we can turn the attackers greatest advantage into a disadvantage. Instead of looking for something bad on a large network of systems, we look for something that is different and investigate it accordingly.

“If the attacker attacks a system on the network, that system will appear different to all of the other systems in some way – allowing the attack to be detected even if we don’t have a signature for exactly what the attacker is doing.  This may sound simple, but you can easily recognise that certain differences are more interesting than others and that is where human skill comes into play.

“You can have automated systems gathering data from all systems, collecting network traffic and pulling in logs from systems. Ultimately, however, you need a human to drive the analysis.”

Auto rivals team up for connected car demo

Rivals BMW, Ford and Groupe PSA, maker of Peugeot and Opel cars, have teamed up with the 5G Automotive Association (5GAA), Qualcomm Technologies and Savari for Europe’s first live demonstration of C-V2X direct communication technology operating across vehicles from multiple auto manufacturers.

The live demonstration also featured a live showcase of C-V2X direct communication technology operating between passenger cars, motorcycles, and roadside infrastructure. C-V2X is a global solution for vehicle-to-everything (V2X) communication in support of improved automotive safety, automated driving and traffic efficiency.

The demonstration exhibited the road safety and traffic efficiency benefits of using C-V2X for Vehicle-to-Vehicle (V2V) collision avoidance, as well as Vehicle-to-Infrastructure (V2I) connectivity to traffic signals and Traffic Management Centers (TMC). C-V2X was operated using real-time direct communications over ITS spectrum and demonstrated its ability to work without cellular network coverage, and underscores its commercial readiness for industry deployment as early as 2020. Superior performance and cost-effectiveness compared to other V2X technologies, along with forward-compatibility with 5G, make C-V2X direct communications a preferred solution for C-ITS applications.

Six demonstrations were shown including: Emergency Electronic Brake Light, Intersection Collision Warning, Across Traffic Turn Collision Risk Warning, Slow Vehicle Warning and Stationary Vehicle Warning, Signal Phase and Timing / Signal Violation Warning and Vulnerable Road User (pedestrian) Warning. The vehicles involved included two-wheel e-scooters provided by BMW Group, and automotive passenger vehicles provided by Ford, Groupe PSA, and BMW Group, all of which were equipped with C-V2X direct communication technology using the Qualcomm® 9150 C-V2X chipset solution.  V2X software stack and application software, along with roadside infrastructure, were provided by industry leader, Savari.

C-V2X is globally supported by a broad automotive ecosystem, which includes the fast growing 5GAA organization.  The 5GAA involves over 85 global members comprised of many leading automakers, Tier-1 suppliers, software developers, mobile operators, semiconductor companies, test equipment vendors, telecom suppliers, traffic signal suppliers and road operators.  

Cellular modems will be key to the C-V2X deployment in vehicles to support telematics, eCall, connected infotainment and delivering useful driving/traffic/parking information. As C-V2X direct communication functionality is integrated into the cellular modem, C-V2X solutions are expected to be more cost-efficient and economical over competing technologies, and benefit from accelerated attach rates.  C-V2X direct communication field validations are currently underway in Germany, France, Korea, China, Japan and the U.S.

C-V2X currently stands as the only V2X technology based on globally recognized 3rd Generation Partnership Project (3GPP) specifications, with ongoing evolution designed to offer forward compatibility with 5G.  C-V2X also leverages and reuses the upper layer protocols defined by the automotive industry, including the European Telecommunications Standards Institute (ETSI) organization. C-V2X includes two complementary transmission modes: 

  • Direct communication as shown in this demonstration for V2V and V2I use cases
  • V2N network communication, which leverages mobile operators for connectivity and delivers cloud-based services, including automated crash notification (ACN, as mandated by eCall), hazard warnings, weather conditions, green light optimal speed advisory (GLOSA), parking spot location, and remote tele-operation to support automated driving, to name a few.

“This demonstration builds on the successful C-V2X showcase we organised with our members Audi, Ford and Qualcomm in Washington DC in April, said Christoph Voigt, Chairman of 5GAA.

“We are excited to witness the growing momentum behind this life-saving technology and to see our members working together to deploy C-V2X, and to make it hit the road as soon as possible.”  

“The BMW Group introduced the first C-ITS use cases already in 2013 with the market introduction of the BMW i3. Today most of envisaged C-ITS use-cases are already institutionalized. With the implementation of C-V2X, the BMW Group accomplishes the last set of the puzzle with a practical path to C-ITS showing quick benefits,” said Christoph Grote, Senior Vice President Electronics, BMW Group. 

“With its ability to safely and securely connect vehicles, along with its evolution into 5G, C-V2X is integral to Ford’s vision for future transportation in which all cars and infrastructure talk to each other,” said Thomas Lukaszewicz, Manager Automated Driving, Ford of Europe. “We are very encouraged by preliminary test results in Europe and elsewhere which support our belief that C-V2X direct communications has superior V2X communication capabilities.”

“We’re moving forward with seamless communication between cars and their environment for enhancing road safety, as well as our customers’ safety,” said Carla Gohin, Group PSA’s Vice President for Research and Advanced Engineering. “Following the first European C-V2X direct communications demonstration we hosted with Qualcomm Technologies last March, we’re pleased to work with leading automotive and technology companies today to highlight that C-V2X interoperability is a reality.” 

“This demonstration of interoperability between multiple automakers is not only another milestone achieved towards C-V2X deployment, but also further validates the commercial viability and global compatibility of C-V2X direct communications for connected vehicles,” said Enrico Salvatori, senior vice president & president, Qualcomm Europe and MEA. “We look forward in continuing to work alongside leaders in the automotive industry, like the 5GAA, BMW Group, Ford, Groupe PSA and Savari, to help advance the automotive industry’s shift towards a safer, connected and more autonomous future.” 

“As one of the V2X pioneers, our company is extremely pleased to continue to help enable the next step in the V2X revolution that we helped start back in 2008,” said Ravi Puvvala, CEO of Savari. “For the last year and a half, the Savari team has worked diligently alongside the dedicated C-V2X engineers in the 5GAA partnership. The resulting string of increasingly impressive demonstrations is continuing to convince the world that C-V2X will soon be deployed around the world.”

Win a Poster Heater with Gadget and Takealot.com

This winter Gadget and Takealot.com are giving away three Poster Heaters, which look like posters but become heaters when you plug them in.

Published

on

Three Gadget readers will each win a unit, valued at R550 each. To enter, follow @GadgetZA and @Takealot on Twitter and tell us on the @GadgetZA account how many Watts the heater consumes.

What’s the big deal about these heaters? Many of us are struggling to keep the balance between soaring electricity costs and the need to keep warm this winter.

However, the recently launched Poster Heater by EasyHeat and distributed in South Africa by Takealot.com is not only one of the most cost effective electric heaters currently on the market, it is also easy to setup and use.

As the name indicates, it is a poster similar to one you would hang on a wall. But, plug it in and it turns into a 300 Watt heater. The Poster Heater isn’t designed to heat hallways or large rooms, but rather smaller ones like a bedroom or a baby’s nursery or a dressing room.

It uses radiant heating, which means that it heats up in a couple of minutes and the heat is directed at the objects or people around it, quickly taking the chill out of the air and providing a comfortable ambient temperature.

The other advantage of radiant heating is that it doesn’t dry out the air like infrared or gas heaters. Users also don’t have to worry about their children or pets getting too close to it because, even though it gets hot, it can be touched.

To enter the competition follow the steps below:

Competition entry details:

1. Follow @GadgetZA and @Takealot on Twitter. (We will ONLY be accepting entires via Twitter, so please don’t enter through the comments section of this article.)

2. Tell us on Twitter, via @GadgetZA, mentioning @Takealot in your posting, how many Watts the Poster Heater consumes.

cleardot.gif3. The competition closes on 31 July 2018.

4. Winners will be notified via Twitter on 1 August and Takealot.com will be in touch to organise delivery.

5. The competition is only open to South African residents.
