F5 Labs has released new figures highlighting how distributed denial of service (DDoS) attacks continue to grow and evolve in EMEA.
According to customer data from F5’s Poland-based Security Operations Center (SOC), 2017 saw a 64% rise in mitigated incidents. EMEA is also firmly in the firing line, accounting for over 51% of reported global DDoS attacks.
Reflecting the spike in activity, F5 reported a 100% growth for EMEA customers deploying Web Application Firewall (WAF) technology in the past year. Meanwhile, anti-fraud solutions adoption increased by 76% and DDoS by 58%.
A key discovery was the relative drop in power for single attacks. Last year, the SOC logged multiple attacks of over 100 Gbps, with some surpassing 400 Gbps.
In 2017, the top attack stood at 62 Gbps. This suggests a move towards more sophisticated Layer 7 DDoS attacks that are potentially more effective and have lower bandwidth requirements. 66% of reported DDoS attacks were multi-vector and required sophisticated mitigation tools and knowledge.
“DDoS threats are on the rise in EMEA compared to the rest of the world, and we’re seeing notable changes in their scope and sophistication compared to 2016,” said Martin Walshaw, senior network engineer at F5.
“Businesses need to be aware of the shift and ensure, as a matter of priority, that the right solutions are in place to halt DDoS attacks before they reach applications and adversely impact on business operations. EMEA is clearly a hotspot for attacks on a global scale, so there is minimal scope for the region’s decision-makers to take their eyes off the ball.”
Four seasons of threat intelligence
Q1 2017 started with a bang, with F5 customers facing the widest range of disruptive attacks recorded to date. User Diagram Protocol (UDP) floods stood out, representing 25% of all attacks. Attackers typically send large UDP packets to a single destination or random ports, disguising themselves as trustworthy entities before stealing sensitive data. The next most common attacks were DNS Reflection (18%) and SYN Flood attacks (16%).
Q1 was also the peak for Internet Control Message Protocol (ICMP) attacks, whereby cybercriminals overwhelm businesses with rapid “echo request” (ping) packets without waiting for replies. In stark contrast, Q1 2016 attacks were a 50/50 split between UDP and Simple Service Discover Protocol (SSDP) floods.
Q2 proved equally challenging, with SYN floods moving to the front of the attack pack (25%), followed by Network Time Protocol and UDP floods (both 20%).
The attackers’ momentum continued into Q3, with UDP floods leading the way (26%). NTP floods were also prevalent (rising from 8% during the same period in 2016, to 22%), followed by DNS reflection (17%).
2017 wound down with more UDP flood dominance (25% of all attacks). It was also the busiest period for DNS reflection, which accounted for 20% of all attacks (compared to 8% in 2017 during the same period).
Another key discovery during Q4 – and one that vividly underlines cybercriminals capacity for agile reinvention – was how the Ramnit Trojan dramatically extended its reach. Initially built to hit banks, F5 Labs found that 64% of its targets during the holiday season were US based e-commerce sites. Other new targets included sites related to travel, entertainment, food, dating and pornography. Other observed banking Trojans extending their reach include Trickbot, which infects its victims with social engineering attacks, such as phishing or malvertising, to trick unassuming users into clicking malware links or downloading malware files.
“Attack vectors and tactics will only continue to evolve in EMEA,” said Walshaw.
“It is vital that businesses have the right solutions and services in place to safeguard apps wherever they reside. 2017 showed that more internet traffic is SSL/TLS encrypted, so it is imperative that DDoS mitigation solutions can examine the nature of these increasingly sophisticated attacks. Full visibility and greater control at every layer are essential for businesses to stay relevant and credible to customers. This will be particularly important in 2018 as the EU General Data Protection Regulations come into play.”
Small South African town goes smartphone-only
Vodacom partners with farming business to upgrade all residents of Wakkerstroom from 2G devices to smartphones
All residents of the small town of Wakkerstroom, which straddles Mpumalanga and kwaZulu-Natal provinces, have had their 2G feature phones upgraded to 3G devices.
The initiative is a result of Vodacom partnering with BPG Langfontein, a farming business that employs the majority of the people living in Wakkerstroom. It is now the first smartphone-only town in South Africa. This is a model the network provider says it hopes to replicate across the country as part of its mission to connect people who live in deep rural areas and are still dependent on 2G networks.
Wakkerstroom, is the second oldest town in Mpumalanga province, on the KwaZulu-Natal border, 27 km east of Volksrust and 56 km south-east of Amersfoort.
“There are growing expectations for big corporates the size of Vodacom to serve a social purpose, and for us to use our resources and core capabilities to make a significant contribution in transforming the lives of ordinary people,” says Zakhele Jiyane, Managing Executive for Vodacom Mpumalanga. “We are helping to remove communication barriers, so that citizens in the area can be part of the digital revolution and reap the associated benefits. By moving the more than 1400 farm workers from 2G to 3G devices, this will also free much needed spectrum and this spectrum can be re-farmed to provide for faster networks such as 3G and 4G.
“Crucially, the move opens a new world of connectivity for farm workers in Wakkerstroom. As a result, most people in the area will now be able to use the Vodacom network to connect on the net and access online government services, eHealth services such as Mum&Baby and eCommerce. Learners can now surf the internet for the first time and access Vodacom’s eSchool free of charge and those who are actively looking for jobs can start using their smartphones and tablets to apply for jobs over the internet on Vodacom’s zero-rated career sites. This will be key for driving growth to the benefit of people living in this area.”
Vodacom has already deployed 4G base stations in Wakkestroom as part of this initiative.
For the next phase of this project, says Vodacom, it is going to educate the farm workers about data and the benefits of the Internet. Vodacom will also look at various ways in which it can help empower members of this community in areas of education, gender-based violence and health.
10 more African countries join Facebook fact-checking
Facebook today announced the expansion of its Third-Party Fact-Checking programme to 10 additional African countries, which now join Kenya, Nigeria, South Africa, Cameroon and Senegal in the project,
In partnership with Agence France-Presse (AFP), the France 24 Observers, Pesa Check and Dubawa, this programme forms part of its work in helping assess the accuracy and quality of news people find on Facebook, whilst reducing the spread of misinformation on its platform.
Working with a network of fact-checking organizations, certified by the non-partisan International Fact-Checking Network, third-party fact-checking will now be available in Ethiopia, Zambia, Somalia and Burkina Faso through AFP, Uganda and Tanzania through both Pesa Check and AFP, Democratic Republic of Congo and Cote d’Ivoire through the France 24 Observers and AFP, Guinea Conakry through the France 24 Observers, and Ghana through Dubawa.
Feedback from the Facebook community is one of many signals Facebook uses to raise potentially false stories to fact-checkers for review. Local articles will be fact-checked alongside the verification of photos and videos. If one of our fact-checking partners identifies a story as false, Facebook will show it lower in News Feed, significantly reducing its distribution.
Kojo Boakye, Facebook Head of Public Policy, Africa, said: “The expansion of third-party fact-checking to now cover 15 countries in a little over a year shows firsthand our commitment and dedication to the continent, alongside our recent local language expansion as part of this programme. Taking steps to help tackle false news on Facebook is a responsibility we take seriously, we know misinformation is a problem, and these are important steps in continuing to address this issue. We know that third-party fact-checking alone is not the solution, it is one of many initiatives and programmes we are investing in to help to improve the quality of information people see on Facebook. While we’ve made great progress, we will keep investing to ensure Facebook remains a place for all ideas, but not for the spread of false news.”
When third-party fact-checkers fact-check a news story, Facebook will show these in Related Articles immediately below the story in News Feed. Page Admins and people on Facebook will also receive notifications if they try to share a story or have shared one in the past that’s been determined to be false, empowering people to decide for themselves what to read, trust, and share.
Providing fact-checking in English and French across eight countries, Phil Chetwynd, AFP Global News Director said: “AFP is delighted to be expanding its fact-checking project with Facebook. We are known for the high quality of our journalism from across Africa and we will be leveraging our unparalleled network of bureaus and journalists on the continent to combat misinformation.”
Eric Mugendi, Managing Editor from Pesa Check who will provide fact-checking services in Swahili and English added: “Social networks like Facebook haven’t just changed how Africans consume the news. Social media is often the primary access to digital content or the ‘Internet’ for many Africans. They shape our perceptions of the world, our public discourse, and how we interact with public figures. This project helps us dramatically expand our fact-checking to debunk claims that could otherwise cause real-world harm. The project helps us respond more quickly and directly. We’re seeing real positive results in our interactions with both publishers and the public itself. The project also helps our fact-checks reach a far larger audience than we would otherwise. This has helped us better understand the information vacuum and other viral dynamics that drive the spread of false information in Africa. Our growing impact is a small but tangible contribution to better informed societies in Africa.”
Caroline Anipah, Programme Officer, Dubawa (Ghana) said: “Dubawa is excited to be in Ghana where the misinformation and disinformation have become widespread as a result of technological advancement and increasing internet penetration. Dubawa intends to raise the quality of information available to the public with the ultimate aim of curbing the spread of misinformation and disinformation and promoting good governance and accountability.”
Derek Thomson, editor-in-chief of the France 24 Observers, said: “Our African users are constantly sending us questionable images and messages they’ve received via social media, asking us ‘Is this true? Can you check it?’ It’s our responsibility as fact-checking journalists to verify the information that’s circulating, and get the truth back out there. Participating in the Facebook programme helps ensure that our fact-checks are reaching the people who shared the false news in the first place.”
