The revelation comes at a time when South Africa is witnessing consistent complexities in its cybersecurity threat landscape.
The revelations were made in Trend Micro’s 2023 Midyear Cybersecurity Threat Report, which presents findings gleaned from in-depth telemetry involving millions of business and consumer clients. The research sheds light on both threat actor actions and new trends in criminal tactics, providing security defenders working to outwit crafty cybercriminals with useful advice.
In the first half of 2023, Trend Micro was able to block around 15 million malware families, with ransomware posing a significant threat to regional organizations. Notably, only in June were around 2,500 ransomware detections reported. The Midyear Report digs deeply into the evolving strategies used by ransomware groups, including how they have modified tools and methods for more effective data extraction and how their revenue models have changed.
One of the risks arises from the newly discovered ‘Mimic’ ransomware, which cleverly deploys legit search engine tools to locate files for encryption. Apparently, Mimic has certain links with the notorious Conti ransomware group, further indicating the cooperation between these criminal organizations for the sake of lowering costs, expanding their market reach, and engaging in ongoing criminal activity. The report also highlights a change in ransomware groups' priorities, with a specific focus on data exfiltration involving bitcoin theft and corporate email compromise (BEC).
Another trend that came to light in 2023 is the growing use of AI by threat actors in conducting cybercrimes. On one hand, South African companies are adopting AI technologies to up their game, and threat actors are also embracing high-end technologies to design more complicated cyber scams. These scams may include virtual kidnapping, where it may use AI for deepfake voice generation to force the victims into paying the ransom amounts.
Additionally, AI tools like ChatGPT have given cybercriminals the ability to automate data collection, create target groups, and recognize weak behaviours, making it simpler to launch harpoon-whaling attacks. These attacks entail the deceptive targeting of executives via emails that are highly tailored, urgently written, and contain details specific to the target. The effort needed to target CEOs has been greatly decreased thanks to the usage of AI, making it simpler to shoot for a big target.
Threat actors are continually looking for new ways to attack people as advancements progress. Attackers want to gain access to user account data to enable crimes with the rise of linked cars. Cybercriminals may identify and break into vehicles for theft or other illegal acts after hijacking accounts or acquiring credentials through phishing or malware; they may even target the owner's home location for a break-in while they are away.
The reason behind threat actors’ interest in South Africa is the increased uptake of smart home networks (SHN). Trend Micro found more than 1.5 million inbound SHN attacks in the nation during the first half of 2023. Smaller platforms, such as file transfer services like MOVEit, business communications software like 3CX, and print management software options like PaperCut, have become more vulnerable as a result of these attacks.
Zaheer Ebrahim, Solutions Architect for the Middle East and Africa at Trend Micro further highlights that the unending complexities now seen in hacker tactics pose a severe threat to local businesses. Given the constantly changing world of digital security, he emphasizes the significance of identifying potential risks and threats in order to make wise decisions and proactively build cybersecurity defences.
A recent TGC Forensics report highlights the spike in cybercrime activities. It notes that there has been a 356% increase in identity frauds between April 2022 and April 2023, citing a report by Southern African Fraud Prevention Services.
According to Jackie Smith, head of the Buyers Trust – a subsidiary of Ooba Group – South Africa is vulnerable due to a number of variables, including economic growth and a quickly evolving digital environment.
He further noted that cybercrimes are rather “easy to commit,” and that around 90% goes unreported.
“Cybercrimes can be committed by anyone with access to a cellphone and an internet connection, making these crimes incredibly easy to perpetrate[…]And, with only an estimated 10% of cybercrimes reported to the police, criminals feel they can operate without consequence,” he added.
In regards to the Cybercrimes Act bill, which was signed in June 2021, media law experts claimed that the act missed opportunity. He said that although the act sought to address important problems South Africa faced, the language employed was “broad and vague.”
Another reason why South Africa is turning into a cybercrime hub is because of a lack in proper training of police officers to deal with cybercrime cases. This further flourish organized crime syndicates notably in the property sector, which has turned into a convenient target for cybercriminals.
Smith claimed that because to the transactions made by buyers, sellers, tenants, and landlords, these parties are vulnerable to phishing scams and data breaches. One of the most common phishing scam being the ‘deposit phishing schemes.’
Deposit phishing schemes are carried out where cybercriminals impersonate legitimate real estate agents or legal officials to secretly intercept emails between buyers and sellers. This way, they reroute the buyer's deposit into their accounts. The fraudsters are so precise that they blur the difference between genuine emails and the fraudulent ones.
In order to protect oneself from these phishing scams, Smith has suggested the following measures:
As claimed by the authorities, both of the mentioned situations have given rise to newer opportunities for online criminals to rake in large assets without risking being caught.
This growth has a direct impact on the rest of the world, where many victims of “hugely lucrative” fraud live, a senior police official says.
According to Prof. Landry Signé, a senior scholar and study author at Brookings Institution, the Covid-19 crisis has apparently resulted in the growth of digitalization globally. As online activities boosted, criminals, targeted critical digital infrastructure.
“The Covid-19 pandemic has accelerated digitalization around the world, but as life has shifted increasingly online, cybercriminals have exploited the opportunity to attack vital digital infrastructure […] States across Africa have emerged as a favorite target of cybercriminals, with costly consequences,” says Professor Signé.
Nigerian Black Axe Gang
Interpol describes online frauds like banking and credit card frauds as the most pervasive and severe cyber threat across Africa. The Covid-19 pandemic has resulted in a sustained rise in the number and advancement of cyber-attacks, with more than half being targeted at online banking platforms, as per the analysts.
A major operation organized by Interpol this month, across 14 countries, emphasises the scale of cybercrimes across the continent and beyond.
Police later detained more than 70 alleged fraudsters in connection with the Nigerian cyber threat group known as ‘Black Axe’ in South Africa, Nigeria, and Ivory Coast, as well as in the Middle East, Europe, south-east Asia, and the US.
Moreover, about 50 residents were being investigated, with $1 million confiscated from bank accounts. Additionally, an apartment building, three vehicles, tens of thousands of dollars, and about 12,000 sim cards were seized.
Reportedly the Black Axe gang started out as a student organization, originating in Benin City, in the 1970s and later evolved into a worldwide criminal network, specializing in frauds. As per the US court filings, the group later claimed a regional headquarters in South Africa in the year 2013.
Authorities reportedly discovered phones and other equipment that were known to be used by Black Axe scammers, in Ireland. While tracing the group’s vocabulary, the investigators linked the group to West Africa.
A former South African criminal intelligence official says that although the fraudulent activities have comparatively reduced, one cannot assume that the organization has ceased operations. The official continued that these criminals manage their operations very well, and they have found solutions to all the issues.
A Major Base for Organized Crimes
As reported by The Guardian, South Africa has emerged as a headquarter for organized crimes.
South Africa apparently hosts the Black Axe organization, while also helping them proliferate worldwide. In this regard, Interpol further said, “as well as hosting Black Axe groups, South Africa also helps enable their spread to other parts of the world … Black Axe members come to South Africa to obtain South African citizenship, which facilitates their travel to the US, Europe or Dubai.”
Along with other acts of cyber fraud, threat actors in Africa generally targets victims via online dating services and apps, deceiving them into false relationships in order to acquire money or sensitive information about the victims.
Not only South Africa, Kenya as well has evolved into a significant base for digital extortion schemes, believes the FBI and Interpol. Thus, making the continent a major base for cybercrime activities.
