Cyber whaling rises in SA

Published

on

Whaling is much like phishing, but hackers target more lucrative targets. Also, unlike phishing, whaling involves targeting fewer individuals and with more specific attacks. SIMEON TASSEV, offers some tips to prevent a company from becoming a whaling target.

One of the largest online security threats to individuals and businesses today doesn’t come from new sophisticated malware tools, but rather from distinctly low-tech phishing and whaling campaigns. A recent survey of IT experts from the US, UK, South Africa and Australia exposed the reality that cyber threats are increasing both in volume and size, and that up to 55% of organisations have seen a rise in whaling email attacks over the last three months of 2015. What is the difference between whaling and phishing? Realistically, “whaling” is just another term for “phishing”, the difference between the two lies in the size of the fish, and thus “whaling” refers to bigger, more lucrative targets.

Whaling involves targeting fewer individuals but the attacks are more specific. Whereas phishing is based on volume, whaling is the opposite and targets a much smaller audience, which is usually an organisation’s “big phish”. These are usually high-value individuals whose credentials or access to data, if compromised, could endanger the entire business; which is why these kind of attacks are also called “Business Email Compromise” attacks. These kinds of threats are harder to detect because they are stealthier and fewer in number than widespread phishing campaigns.   Targets of choice for whalers include senior executives and high-level officials in private businesses, as well as those with privileged access to government information.

The anatomy of a whaling attack

Whaling attacks are generally directed at business executives at large organisations and the intention behind these attacks is to trick financial staff into making fraudulent wire transfers to bank accounts controlled by whalers. How do these attackers get it right? Their targeted campaigns typically involve emails that appear to be from the CEO, Chief Financial Officer or other senior executive to an individual within the company who holds the authority to make electronic transfers on behalf of the organisation.

These emails make use of compelling language that conveys a sense of urgency to get the recipient to act as quickly as possible in response to the email. An example of such an attack is where an email comes through, purportedly from the CEO, asking finance staff to rush through a payment to a supplier that the executive cannot handle because they are out of the office.

Attacks from the inside

Research shows that most whaling attacks pretend to be from the CEO (72%), while 36% had seen whaling emails attributed to the CFO, which means that this type of targeted attack relies on a significant amount of prior research into the targeted organisation to allow attackers to identify their target correctly and obtain the most successful result possible. Whalers do their research on corporate databases and make use of social networking sites like Facebook, LinkedIn and Twitter to trawl for information. It is because whaling emails rely on social engineering to trick their targets into doing something, rather than tricking them to click on a hyperlink or malicious attachment, that whaling emails are harder to detect when compared to phishing emails.

Protecting your company from whaling attacks

From an organisational point of view, such attacks can be approached with the same mindset applied for corporate espionage security, as they are essentially the same. The controls are still along the lines of anti-phishing technology which is linked to email, but because of the targeted nature of the whaling attack, it can be a lot more difficult for technology to pick up, which is why it’s important to add an awareness element to preventive measures taken.

This means educating senior management, key personnel and finance teams about this specific kind of attack and asking them to be more suspicious of requests received through email. While there are technologies that can be used to confirm, for example, the originator’s email, it is incumbent on the recipient to confirm or identify the source of communication before they take action on the email and to this end, finance team procedures will need to be reviewed in order to prevent whaling, specifically how payments to external third parties are authorised.

Furthermore, senior executives need to be careful what kind of contact information is available for them in the public domain. This means that a company should have a policy in place which refers to access control to and disclosure of senior personnel contact information. Realistically, someone may not have an issue giving a contact number for the help desk, but they should have an issue giving a contact number for their senior executives and access controls should be implemented to hinder information gathering tactics.

It is also advisable to make use of various technological measures that simplify the matter. In terms of validating the source of emails, like with phishing, whaling emails can have the source of the email description and the technical structure of the email validated, using targeted threat prevention solutions integrated with email security.  Also useful is inbound email stationery that marks and alerts personnel to emails that have come from outside the corporate network. Additionally, domain name registration alerts can be used to notify an organisation when domains are created that closely resemble that corporate’s domain, making it that much harder for a whaler to launch a successful attack from within.

Prepare your cam to capture the Blood Moon

On 27 July 2018, South Africans can witness a total lunar eclipse, as the earth’s shadow completely covers the moon.

Published

on

Also known as a blood or red moon, a total lunar eclipse is the most dramatic of all lunar eclipses and presents an exciting photographic opportunity for any aspiring photographer or would-be astronomers.

“A lunar eclipse is a rare cosmic sight. For centuries these events have inspired wonder, interest and sometimes fear amongst observers. Of course, if you are lucky to be around when one occurs, you would want to capture it all on camera,” says Dana Eitzen, Corporate and Marketing Communications Executive at Canon South Africa.

Canon ambassador and acclaimed landscape photographer David Noton has provided his top tips to keep in mind when photographing this occasion.   In South Africa, the eclipse will be visible from about 19h14 on Friday, 27 July until 01h28 on the Saturday morning. The lunar eclipse will see the light from the sun blocked by the earth as it passes in front of the moon. The moon will turn red because of an effect known as Rayleigh Scattering, where bands of green and violet light become filtered through the atmosphere.

A partial eclipse will begin at 20h24 when the moon will start to turn red. The total eclipse begins at about 21h30 when the moon is completely red. The eclipse reaches its maximum at 22h21 when the moon is closest to the centre of the shadow.

David Noton advises:

  1. Download the right apps to be in-the-know

The sun’s position in the sky at any given time of day varies massively with latitude and season. That is not the case with the moon as its passage through the heavens is governed by its complex elliptical orbit of the earth. That orbit results in monthly, rather than seasonal variations, as the moon moves through its lunar cycle. The result is big differences in the timing of its appearance and its trajectory through the sky. Luckily, we no longer need to rely on weight tables to consult the behaviour of the moon, we can simply download an app on to our phone. The Photographer’s Ephemeris is useful for giving moonrise and moonset times, bearings and phases; while the Photopills app gives comprehensive information on the position of the moon in our sky.  Armed with these two apps, I’m planning to shoot the Blood Moon rising in Dorset, England. I’m aiming to capture the moon within the first fifteen minutes of moonrise so I can catch it low in the sky and juxtapose it against an object on the horizon line for scale – this could be as simple as a tree on a hill.

 

  1. Invest in a lens with optimal zoom  

On the 27th July, one of the key challenges we’ll face is shooting the moon large in the frame so we can see every crater on the asteroid pockmarked surface. It’s a task normally reserved for astronomers with super powerful telescopes, but if you’ve got a long telephoto lens on a full frame DSLR with around 600 mm of focal length, it can be done, depending on the composition. I will be using the Canon EOS 5D Mark IV with an EF 200-400mm f/4L IS USM Ext. 1.4 x lens.

  1. Use a tripod to capture the intimate details

As you frame up your shot, one thing will become immediately apparent; lunar tracking is incredibly challenging as the moon moves through the sky surprisingly quickly. As you’ll be using a long lens for this shoot, it’s important to invest in a sturdy tripod to help capture the best possible image. Although it will be tempting to take the shot by hand, it’s important to remember that your subject is over 384,000km away from you and even with a high shutter speed, the slightest of movements will become exaggerated.

  1. Integrate the moon into your landscape

Whilst images of the moon large in the frame can be beautifully detailed, they are essentially astronomical in their appeal. Personally, I’m far more drawn to using the lunar allure as an element in my landscapes, or using the moonlight as a light source. The latter is difficult, as the amount of light the moon reflects is tiny, whilst the lunar surface is so bright by comparison. Up to now, night photography meant long, long exposures but with cameras such as the Canon EOS-1D X Mark II and the Canon EOS 5D Mark IV now capable of astonishing low light performance, a whole new nocturnal world of opportunities has been opened to photographers.

  1. Master the shutter speed for your subject 

The most evocative and genuine use of the moon in landscape portraits results from situations when the light on the moon balances with the twilight in the surrounding sky. Such images have a subtle appeal, mood and believability.  By definition, any scene incorporating a medium or wide-angle view is going to render the moon as a tiny pin prick of light, but its presence will still be felt. Our eyes naturally gravitate to it, however insignificant it may seem. Of course, the issue of shutter speed is always there; too slow an exposure and all we’ll see is an unsightly lunar streak, even with a wide-angle lens.

 

On a clear night, mastering the shutter speed of your camera is integral to capturing the moon – exposing at 1/250 sec @ f8 ISO 100 (depending on focal length) is what you’ll need to stop the motion from blurring and if you are to get the technique right, with the high quality of cameras such as the Canon EOS 5DS R, you might even be able to see the twelve cameras that were left up there by NASA in the 60’s!

How Africa can embrace AI

Currently, no African country is among the top 10 countries expected to benefit most from AI and automation. But, the continent has the potential to catch up with the rest of world if we act fast, says ZOAIB HOOSEN, Microsoft Managing Director.

To play catch up, we must take advantage of our best and most powerful resource – our human capital. According to a report by the World Economic Forum (WEF), more than 60 percent of the population in sub-Saharan Africa is under the age of 25.

These are the people who are poised to create a future where humans and AI can work together for the good of society. In fact, the most recent WEF Global Shapers survey found that almost 80 percent of youth believe technology like AI is creating jobs rather than destroying them.

Staying ahead of the trends to stay employed

AI developments are expected to impact existing jobs, as AI can replicate certain activities at greater speed and scale. In some areas, AI could learn faster than humans, if not yet as deeply.

According to Gartner, while AI will improve the productivity of many jobs and create millions more new positions, it could impact many others. The simpler and less creative the job, the earlier, a bot for example, could replace it.

It’s important to stay ahead of the trends and find opportunities to expand our knowledge and skills while learning how to work more closely and symbiotically with technology.

Another global study by Accenture, found that the adoption of AI will create several new job categories requiring important and yet surprising skills. These include trainers, who are tasked with teaching AI systems how to perform; explainers, who bridge the gap between technologist and business leader; and sustainers, who ensure that AI systems are operating as designed.

It’s clear that successfully integrating human intelligence with AI, so they co-exist in a two-way learning relationship, will become more critical than ever.

Combining STEM with the arts

Young people have a leg up on those already in the working world because they can easily develop the necessary skills for these new roles. It’s therefore essential that our education system constantly evolves to equip youth with the right skills and way of thinking to be successful in jobs that may not even exist yet.

As the division of tasks between man and machine changes, we must re-evaluate the type of knowledge and skills imparted to future generations.

For example, technical skills will be required to design and implement AI systems, but interpersonal skills, creativity and emotional intelligence will also become crucial in giving humans an advantage over machines.

“At one level, AI will require that even more people specialise in digital skills and data science. But skilling-up for an AI-powered world involves more than science, technology, engineering and math. As computers behave more like humans, the social sciences and humanities will become even more important. Languages, art, history, economics, ethics, philosophy, psychology and human development courses can teach critical, philosophical and ethics-based skills that will be instrumental in the development and management of AI solutions.” This is according to Microsoft president, Brad Smith, and EVP of AI and research, Harry Shum, who recently authored the book “The Future Computed”, which primarily deals with AI and its role in society.

Interestingly, institutions like Stanford University are already implementing this forward-thinking approach. The university offers a programme called CS+X, which integrates its computer science degree with humanities degrees, resulting in a Bachelor of Arts and Science qualification.

Revisiting laws and regulation

For this type of evolution to happen, the onus is on policy makers to revisit current laws and even bring in new regulations. Policy makers need to identify the groups most at risk of losing their jobs and create strategies to reintegrate them into the economy.

Simultaneously, though AI could be hugely beneficial in areas such as curbing poor access to healthcare and improving diagnoses for example, physicians may avoid using this technology for fear of malpractice. To avoid this, we need regulation that closes the gap between the pace of technological change and that of regulatory response. It will also become essential to develop a code of ethics for this new ecosystem.

Preparing for the future

With the recent convergence of a transformative set of technologies, economies are entering a period in which AI has the potential overcome physical limitations and open up new sources of value and growth.

To avoid missing out on this opportunity, policy makers and business leaders must prepare for, and work toward, a future with AI. We must do so not with the idea that AI is simply another productivity enhancer. Rather, we must see AI as the tool that can transform our thinking about how growth is created.

It comes down to a choice of our people and economies being part of the technological disruption, or being left behind.
