In 20 years, DDoS attacks have gone from being a novelty to a nuisance, and today they represent a threat against the availability and functionality of websites. BRYAN HAMMAN of Arbor Networks looks back at some of the attacks through the years.
Distributed Denial of Service (DDoS) attacks are more popular and dangerous today than at any time in history. In 20 years, DDoS attacks have gone from being a novelty to a nuisance, and finally today they represent a serious threat against the availability and functionality of websites, online services and applications.
This is according to Arbor Network’s territory manager for Sub-Saharan Africa, Bryan Hamman, who says, “Easy-to-use tools and cheap attack services have widened the potential net that DDoS attacks can cast. Today, anyone with a grievance and an Internet connection can launch an attack. If we take a look back about 20 years or so, historic news headlines and the increasing size of attacks through the years indicate that this problem isn’t going to go away.”
Looking back at some of the attacks down the years
· 1996: Internet service provider (ISP) PANIX is struck by a sustained DDoS attack, affecting businesses that use Panix as their ISP.
· 1996: CERT/ CC – the Computer Emergency Response Team/ Coordination Center, a government-funded research and development centre based at Carnegie Mellon University in Pittsburgh – releases an advisory on the growing phenomenon of TCP SYN floods using spoofed source IP addresses.
· 1997: The world sees the arrival of early DDoS tools, such as Trinoo, Tribe Flood Network, TFN2K, Shaft, and others, often coded by their authors. Primitive DDoS networks emerge, using IRC and Eggdrop or the Sub7 Trojan.
· 1998: The document RFC 2267 is published, which details how network administrators can defeat DDoS attacks via anti-spoofing measures. This document eventually becomes a best current practice adopted by many networking vendors.
· 1998: The Smurf Amplifier Registry is launched to help discover and disable “Smurf” amplifiers, which are abused in DDoS attacks. Smurf Attacks use a spoofed broadcast ICMP ping to then reflect back to a victim to create the attack traffic. By 2012 over 193,000 networks have been found and fixed.
· 1998: Michael Calce, aka 15-year-old ‘Mafiaboy’, launches sustained DDoS attacks on multiple major eCommerce sites including Amazon, CNN, Dell, E*Trade, eBay, and Yahoo!. At the time, Yahoo! was the biggest search engine in the world. He is investigated by the FBI. The Montreal Youth Court sentenced him on September 12, 2001, to eight months of “open custody”, one year of probation, restricted use of the Internet, and a small fine.
· 2002: Significant “Smurf” attacks strike the root DNS servers and cause some outages for some sites. The attacks are eventually repelled. Total traffic eventually hits 900 Mbps.
· 2007: The former Soviet republic of Estonia is hit with sustained DDoS attacks following diplomatic tensions with Russia. The issues arise after Estonia moves a statue honouring Soviet forces who served in World War II against Nazi Germany.
· 2008: Russia is accused of attacking Georgian government websites in a cyber war to accompany its military bombardment, weeks before the invasion of the disputed territory of South Ossetia by Russian troops.
· 2008: Project Chanology is launched by members of “Anonymous”, a leaderless Internet-based group, in response to the Church of Scientology trying to remove an infamous Tom Cruise interview video from the Internet. Project Chanology used DDoS as part of its measures to try to disrupt the Church of Scientology’s operations.
· 2011: Members of Anonymous launch attacks against the sites of PayPal, Visa, and MasterCard in 2011 after the payment service providers refused to process financial donations intended for WikiLeaks.
· 2011: A DDoS attack on Sony is proportedly used to block the detection of a data breach that leads to the extraction of millions of customer records for PlayStation Network users.
· 2011 to 2012: Between December 2011 and March 2012, against a background of political tension in Russia including presidential elections, which were fraught with political demonstrations, DDoS attacks enter the political landscape, with DDoS attacks on both opposition as well as pro-government sites. The world sees Russian cybercriminal methods being used for political ends.
· 2012: Similarly, although arguably not so widely, DDoS attacks are used for political reasons when Canada’s New Democrat Party sees its leadership election negatively affected by a DDoS attack that delays voting and reduced turnout.
· 2012: Unknown groups hit various US and UK government-related websites in protest at these governments’ Wikileaks position.
· 2013: FBI says more cooperation with banks is key in probing cyberattacks.
· 2013: Largest attack reaches 300Gbps – Dutch anti-spam website Spamhaus is targeted for naming and blacklisting cybercrime hosting enterprises, spam and botnet operations.
· 2014: PlayStation Network and Xbox Live are attacked on Christmas Day.
· 2014: In Hong Kong, a huge attack is carried out against the territory’s pro-democracy websites. While many assumed that the culprit would have been the Chinese government, this is not necessarily certain. The attacker could, however, be someone who is not sympathetic with the Hong Kong democracy movement, or someone trying to make the Chinese government look bad.
· 2015: The Turkish Internet is hit with a massive DDoS attack, which came in the wake of Turkey shooting down a Russian military aircraft.
· 2015: British phone and broadband provider, TalkTalk, which has over four million UK customers, is hit by a DDoS attack, which is used as a smokescreen while customers’ personal information is stolen.
· 2015: On New Year’s Eve of 2015, the BBC’s entire domain, including its on-demand television and radio player, is down for three hours and continues to have issues for the rest of the day. The attack is claimed by a group called the “New World Hackers”.
· 2016: An IoT botnet targets a major international event with sophisticated, large-scale DDoS attacks sustaining 500 gb/sec in attack traffic for the duration of the event.
· 2016: The Mirai IoT botnet launches 1Tbps multi vector DDoS attack against DNS infrastructure, taking many of the world’s most popular websites offline.
Looking forward – where to from here?
Hamman says, “We can see clearly, when we look at the timeline of some of the most prominent DDoS attacks over the past two decades, that perpetrators launch these attacks for a variety of reasons. They can be hackers who want to make a statement, as in the case of Mafiaboy; governments of countries at war using cyberwarfare tactics as part of their general arsenal; and criminals trying to blackmail online businesses.
“There are also examples when cyber activists show displeasure against their targets, such as the 2011 attacks by members of Anonymous against the sites of PayPal, Visa and MasterCard, and the 2013 attacks against Spamhaus. The online gaming industry has also been targeted, with the blame generally going to disgruntled players or even competitors. We’ve also seen instances when DDoS attacks are used as a smokescreen to camouflage or draw attention away from other criminal activity an attacker might be doing, such as stealing data from the victim’s network, as in the 2015 example of the UK telecom TalkTalk last year.
Hamman says the IoT brings new demands and requirements to DDoS protection. He adds, “The Mirai IoT botnet reminds us that manufacturers and vendors also have a growing responsibility with respect to their technology and how it will be applied in diverse environments. They need to test for and consider the potential for exploitation. Ideally, all devices should be assessed for risk at the manufacturer and then again by those who are responsible for selling/ implementing them in enterprises.”
Hamman concludes, “Previously, it used to be that only certain types of business would be likely targets for a DDoS attack, with finance, gaming and e-commerce at the top of the list. Today, any business, for any reason, can become a target of a DDoS attack. A number of DDoS-for-hire services, for example, will take down a competitor’s website for any business that wants to hire them.
“The only answer, therefore, is to ensure you are protected. Arbor provides the industry’s most comprehensive suite of DDoS attack protection products and services for the enterprise, cloud/ hosting and service provider markets, with the required deployment model, scalability and pricing flexibility to meet the DDoS protection needs of any organisation operating online today.”
Online retail gets real
After decades of experience in selling online, retailers still seek out the secret of reaching the digital consumer, writes ARTHUR GOLDSTUCK.
It’s been 23 years since the first pizza and the first bunch of flowers was sold online. One would think, after all this time, that retailers would know exactly what works, and exactly how the digital consumer thinks.
Yet, in shopping-mad South Africa, only 4% of adults regularly shop online. One could blame high data costs, low levels of tech-savviness, or lack of trust. However, that doesn’t explain why a population where more than a quarter of people have a debit or credit card and almost 40% of people use the Internet is staying away.
The new Online Retail in South Africa 2019 study, conducted by World Wide Worx with the support of Visa and Platinum Seed, reveals that growth is in fact healthy, but is still coming off a low base. This year, the total sale of retail products online is expected to pass the R14-billion mark, making up 1.4% of total retail.
This figure represents 25% growth over 2017, and comes after the same rate of growth was seen in 2017. At this rate, it is clear that online retail is going mainstream, driven by aggressive marketing, and new shopping channels like mobile shopping.
But it is equally clear that not all retailers are getting it right. According to the study, the unwillingness of business to reinvest revenue in developing their online presence is one of the main barriers to long-term success. Only one in five companies surveyed invested more than 20% of their online turnover back into their online store. Over half invested less than 10% back.
On the surface, the industry looks healthy, as a surprisingly high 71% of online retailers surveyed say they are profitable. But this brings to mind the early days of Amazon.com, in 1996, when founder Jeff Bezos was asked when it would become profitable.
He declared that it would not be profitable for at least another five years. And if it did, he said, it would be in big trouble. He meant that it was so important for long-term sustainability that Amazon reinvest all its revenues in customer systems, that it could not afford to look for short-term profits.
According to the South African study, the single most critical factor in the success of online retail activities is customer service. A vast majority, 98% of respondents, regarded it as important. This positions customer service as the very heart of online retail. For Amazon, investment back into systems that would streamline customer service became the key to the world’s digital wallets.
In South Africa online still make up a small proportion of overall retail, but for the first time we see the promise of a broader range of businesses in terms of category, size, turnover and employee numbers. This is a sign that our local market is beginning to mature.
Clothing and apparel is the fastest growing sector, but is also the sector with the highest turnover of businesses. It illustrates the dangers of a low barrier to entry: the survival rate of online stores in this sector is probably directly opposite to the ease of setting up an online apparel store.
A fast-growing category that was fairly low on the agenda in the past, alcohol, tobacco and vaping, has benefited from the increased online supply of vapes, juices and accessories. It also suggests that smoking bans, and the change in the legal status of marijuana during the survey, may have boosted demand.
In the coming weeks, we can expect online retail to fall under the spotlight as never before. Black Friday, a shopping tradition imported “wholesale” from the United States, is expected to become the biggest online shopping day of the year in South Africa, as it is in the USA.
Initially, it was just a gimmick in South Africa, attempting to cash in on what was a purely American tradition of insane sales on the Friday after Thanksgiving Day, which occurs on the third Thursday of November every year. It is followed by Cyber Monday, making the entire weekend one of major promotions and great bargains.
It has grown every year in South Africa since its first introduction about six years ago, and last year it broke into the mainstream, with numerous high profile retailers embracing it, and many consumers experiencing it for the first time.
It is now positioned as the prime bargain day of the year for consumers, and many wait in anticipation for it, as they do in the USA. Along with Cyber Monday, it provides an excuse for retailers to go all out in their marketing, and for consumers to storm the display shelves or web pages. South African shoppers, clearly, are easily enticed by bargains.
Word of mouth around Black Friday has also grown massively in the past two years, driven by both media and shoppers who have found ridiculous bargains. As news spreads that the most ridiculous of the bargains are to be had online, even those who were reticent of digital shopping will be tempted to convert.
The Online Retail in SA 2019 report has shown over the years that, as people become more experienced in using the Internet, their propensity to shop online increases. This is part of the World Wide Worx model known as the Digital Participation Curve. The key missing factor in the Curve is that most retailers do not know how to convert that propensity into actual online shopping behaviour. Black Friday will be one of the keys to conversion.

Reliable satellite Internet?
MzansiSat, a satellite-Internet business, aims to beam Internet connections to places in South Africa which don’t have access to cabled and mobile network infrastructure, writes BRYAN TURNER.
Stellenbosch-based MzansiSat promises to provide cheap wholesale Internet to Internet Service Providers for as little as R25 per Gigabyte. Providers who offer more expensive Internet services could benefit greatly from partnering with MzansiSat, says the company.
“Using MzansiSat, we hope that we can carry over cost-savings benefits to the consumer,” says Victor Stephanopoli, MzansiSat chief operating officer.
The company, which has been spun off from StellSat, has been looking to increase its investor portfolio while it waits for spectrum approval. The additional investment will allow MzansiSat’s satellite to operate in more regions across Africa.
The MzansiSat satellite is being built by Thales Alenia Space, a French company which is also acting as technical partner to MzansiSat. In addition to building the satellite, Thales Alenia Space will also be assisting MzansiSat in coordinating the launch. The company intends to launch the satellite into the 56°E orbital slot in a geostationary orbit, which enables communication almost anywhere in Africa. The launch is expected to happen in 2022.
The satellite will have 76 transponders, 48 of which will be Ku-band and 28 C-band. Ku-band is all about high-speed performance, while C-band deals with weather-resistance. The design intention is for customers of MzansiSat to choose between very cheap, reliable data and very fast, power-efficient data.
C-band is an older technology, which makes bandwidth cheaper and almost never affected by rain but requires bigger dishes and slower bandwidth compared to Ku-band connections. On the other hand, Ku-band is faster, experiences less microwave interference, and requires less power to run – but is less reliable with bad weather conditions.
MzansiSat’s potential military applications are significant, due to the nature of the military being mobile and possibly in remote areas without connectivity. Connectivity everywhere would be potentially be life-saving.
Consumers in remote areas will benefit, even though satellite is higher in latency than fibre and LTE connections. While this level of latency is high (a fifth of a second in theory), satellite connections are still adequate for browsing the Internet and watching online content.
The Internet of Things (IoT) may see the benefits of satellite Internet before consumers do. The applications of IoT in agriculture are vast, from hydration sensors to soil nutrient testers, and can be realised with an Internet connection which is available in a remote area.
Stephanopoli says that e-learning in remote areas can also benefit from MzansiSat’s presence, as many school resources are becoming readily available online.
“Through our network, the learning experience can be beamed into classrooms across the country to substitute or complement local resources within the South African schooling system.”
