A recent audit has reveled that hotels are doubly vulnerable to ransomware attacks as they may not only impede their own systems but they also could seriously impact on their guests by preventing them from using the hotel’s facilities.
South African businesses are becoming increasingly vulnerable to the 400% growth in global ransomware extortion attacks.
According to audit, tax and business advisory firm Grant Thornton, businesses need to act now to ensure that their digital systems are protected and that critical systems are taken offline.
Simple ransomware attacks are relatively straight forward – victims receive an email with a link that contains software that encrypts files on their computer. These victims are then held to hostage until they pay a ransom.
Recently an upmarket hotel in Austria had its electronic key system compromised by hackers who locked management out of its own computer system. Guests were unable to access or leave their hotel rooms and this led to the hotel being forced to pay a ransom of two Bitcoins – an electronic currency that is difficult to trace – equivalent to about $1,800 (R20, 000) to gain access to their system.
Martin Jansen van Vuuren, Director: Advisory Services at Grant Thornton says that the Austrian attack indicates just how easily hotels’ systems can be infiltrated from cyber space.
Jansen van Vuuren says: “Hotels are doubly vulnerable because ransomware attacks may not only impede their systems but they also could seriously impact on their guests by preventing them from using the hotel’s facilities. Part of Hotel management’s risk mitigation should be to work out exactly how these malicious cyber space attacks can affect their operations and even their customers.”
“The security of convenient computer-driven systems is vital because everything from air-conditioning and room management, to sprinkler systems suddenly become vulnerable to external attacks. There is a need to give particular consideration to these risks as we become more reliant on technology in the guest experience.”
Jansen van Vuuren says mobile phones, used as keys in many hotels these days, are also vulnerable as they often do not have the same level of security as a desktop system. Hackers could steal “door keys” via cyber space or simply disable keys causing huge inconvenience. Open WiFi systems, that are by their nature made easy to access for hotel guests, are another potential source for hackers if they are linked to systems which can be used to gain entry to devices and then to lock out users or steal data.
“The biggest weakness for hotels is their public interfaces such as booking systems that need to connect the internal systems and users to third party applications and ultimately customers. The booking system is therefore particularly vulnerable to ransomware attacks and hackers,” said Jansen van Vuuren.
“Many hotels do not have on-site IT support and rely on the Hotel chain’s head office or an external service provider to attend to IT issues. This centralised approach places individual properties at additional risk of attack, as a cyber-attack may not be picked up quickly enough leading to a delay in combating the cyber-attack” he says.
Ransomware attacks quadrupled in 2016 to 4 000 a day
Grant Thornton’s Director of IT Advisory Services, Michiel Jonker, says that while the hotel industry is in the public eye, following the most recent high profile attack, it has to be borne in mind that every industry is at risk.
According to data from the United States Justice Department, ransomware attacks quadrupled in 2016 to an average of 4000 a day. The F.B.I. said the costs to victims of such attacks rose to $209-million (R2, 7bn) in the first three months of 2016, compared with $24-million (R312m) for the whole of 2015.
“Ransomware syndicates are extremely sophisticated, even hosting their own ‘call centres’ which assist you to access your decryption key and undertake not to attack you with the same ransom. They even use algorithms to determine your particular industry, and the ransom price is based on your industry’s perceived ‘wealth’,” says Jonker. “You can’t really prevent these attacks; you can only reduce your attack vulnerability to some extent. Preventive controls are not enough. Organisations will have to rely on corrective controls, most notably backups and disaster recovery plans.”
He says corporate executives have to start seriously considering how their companies will respond to malicious attacks and whether their systems – both critical and simple – are designed to minimise risk to the impact of hackers and ransomware.
He says that Grant Thornton’s IT Advisory team advises clients to take, among many other things, the following steps in order to minimise the risk to some extent:
· Remove admin rights for laptop users to prevent users from inadvertently downloading malicious software;
· Ensure that all systems undergo well-structured backup processes and that they are recoverable;
· Segregate networks so that different network segments are limited to different groups of authorised users;
· Provide database access only to those people who require access; and
· Install antivirus software on all devices including laptops; smart phones and other wearable technologies; and finally
· Use low-code programming platforms to develop apps, as we do, where security has already been incorporated into the platform.
Jonker says that while prevention is better than dealing with the effects of a cyber-attack, it is best practice to isolate certain high risk and critical (especially national) infrastructure networks and systems, so that they are off the grid and entirely inaccessible from cyber space. They only ever link intermittently via a small ‘sterile’ middle system, with neither linked system connected at the same time – a bit like an airlock in a submarine. So an hotel’s external public reservation system might interface hourly via such a sanitised link only.
“At the end of the day you balance security with the need for convenience, availability, functionality and innovation,” says Jonker. “To produce leapfrog new technology most developers are focused on building systems that work, not systems that are secure. We need to change mind sets so that we don’t focus exclusively on functionality but ensure that we build systems that enhance security and privacy in equal measure.
“We believe that technology advances can be hugely beneficial for hotels in creating great guest experiences, but the systems must always be developed with security considerations fully understood and mitigated,” Jonker says.
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.
