New Research from Trend Micro Shows Cyberattacks Relied on Substance Over Size in 2023
Trend Micro Incorporated, a global cybersecurity leader, has revealed that it blocked around 18 million email threats, almost two million malicious URLs and over four million malicious mobile apps targeted at Nigerian businesses and consumers between January and December 2023. This as threat actors deviate from big-batch attacks to focus on a narrower range of more lucrative targets.
These new patterns in the cybercrime landscape are highlighted in the Trend Micro 2023 Annual Cybersecurity Report, which presents highlights from the company’s telemetry covering the broadest attack surface view across millions of commercial and consumer clients.
“Our latest data shows that threat actors are fine-tuning their operations, shifting away from large-scale attacks, and instead focusing on a smaller range of targets but with higher victim profiles for maximum gain with minimum effort. As they continue to double down on tried and tested techniques, they are also delegating and streamlining operations — resulting in bolder, more effective strikes,” says Gareth Redelinghuys, Country Managing Director, African Cluster at Trend Micro.
Attacks focused on substance over quantity are more difficult to block
Though thousands of ransomware attacks were blocked by Trend Micro in Nigeria in 2023, year-on-year research shows that ransomware groups are working smarter instead of harder, prioritising high-value targets over volume.
There has been a general downward trend in ransomware detections, with worldwide detections from 2021 to 2023 averaging less than half of the recorded detections in 2020; however, this should not be misconstrued as a cue for security operations centres and decision-makers to lower their guards. Historically, ransomware attacks were launched in “bulk,” such as spam campaigns with malicious links, but attacks that focus on quantity can more easily be blocked.
What’s more, a continued increase in Trojan FRS threat detections globally could suggest that attackers are using more effective ways to evade preliminary detection by focusing on arrival and defense evasion techniques. Examples of this include Living-Off-The-Land Binaries and Scripts. Because these computer files are non-malicious in nature and local to the operating system, they can be used by threat actors to camouflage their attacks.
Last year, several ransomware families across the world were also observed maximising remote and intermittent encryption, as well as abusing unmonitored virtual machines to bypass Endpoint Detection and Response. Because there is less content used during intermittent encryption, for example, there is less chance of triggering detection.
Gangs are also launching bolder attacks: Prolific groups were some of the most active in 2023: Clop exploited major vulnerabilities, and BlackCat launched a new variant, while also making its extortion public by leveraging the U.S. Security and Exchange Commission’s four-day disclosure requirement to incentivise its victim to communicate more quickly with them.
Email threats – attackers are using more sophisticated ways to avoid detection
This trend towards threat actors opting for quality over quantity is equally present in the patterns observed around email threats. Though email threat detections in Nigeria decreased from more than 45 million in 2021 to 18 million in 2023, the increase in malware detection count over the same period suggests a shift in the threat landscape that finds attackers making use of more sophisticated ways to avoid detection.
Trend Micro’s data also shows a slight decrease in malicious URL detection in Nigeria from 2021 to 2023, indicating that instead of focusing on malicious links to randomly victimise users, criminals are using more targeted operations, such as BEC schemes, where emails are less likely to undergo scrutiny because of how legitimate they look.
Instead of launching attacks on a wider range of users and relying on victims clicking on malicious links in websites and emails, more sophisticated attacks are launched using specificity to trick a narrower field of high-profile victims. This also allows them to bypass early detection layers like network and email filters.
AI-powered phishing attempts are more convincing than ever
Over the course of 2023, AI showed great promise in social engineering attempts globally: its automation proved most useful in mining datasets for actionable information, while generative AI have made phishing on mass scale virtually effortless with error-free and convincing messages. The use of generative AI in phishing attempts is already branching beyond emails and texts to include persuasive audio and video ‘deepfakes’ for an even more business-affecting threat.
Imagine a company that requires live voice authorisation for purchases above a million dollars, for example. An attacker could send a real-seeming email request with a rigged phone number embedded and answer the confirmation call with a deepfaked voice to validate the transaction. These new tactics introduce the possibility of everything from stock market manipulations to democratic or wartime disinformation campaigns, or smear attacks on public figures.
The barriers to entry for techniques like these have fallen away radically with the rise of readily available app-style interfaces like HeyGen. Cybercriminals with no coding knowledge or special computing resources can produce customised high-resolution outputs that are humanly undetectable.
“Looking at the overall trend in decreasing ransomware threats, it might be tempting for local organisations to develop a false sense of security and lower their defenses. However, our research shows that these increasingly sophisticated attacks are going to become more and more difficult for businesses to detect and that they will be increasingly costly when they succeed. IT leaders must refine their processes and protocols to enable their defenses to combat persistence with efficiency,” concludes Zaheer Ebrahim, Solutions Architect, Middle East and Africa at Trend Micro.
Contrary to popular belief, using cutting-edge artificial intelligence tools slowed down experienced software developers when they were working in codebases familiar to them, rather than supercharging their work, a new study found.
AI research nonprofit METR conducted the in-depth study, on a group of seasoned developers earlier this year while they used Cursor, a popular AI coding assistant, to help them complete tasks in open-source projects they were familiar with.
Before the study, the open-source developers believed using AI would speed them up, estimating it would decrease task completion time by 24%. Even after completing the tasks with AI, the developers believed that they had decreased task times by 20%. But the study found that using AI did the opposite: it increased task completion time by 19%.
The study’s lead authors, Joel Becker and Nate Rush, said they were shocked by the results: prior to the study, Rush had written down that he expected “a 2x speed up, somewhat obviously.”
The findings challenge the belief that AI always makes expensive human engineers much more productive, a factor that has attracted substantial investment into companies selling AI products to aid software development.
AI is also expected to replace entry-level coding positions. Dario Amodei, CEO of Anthropic, recently told Axios that AI could wipe out half of all entry-level white collar jobs in the next one to five years.
Prior literature on productivity improvements has found significant gains: one study found using AI sped up coders by 56%, another study found developers were able to complete 26% more tasks in a given time.
But the new METR study shows that those gains don’t apply to all software development scenarios. In particular, this study showed that experienced developers intimately familiar with the quirks and requirements of large, established open source codebases experienced a slowdown.
Other studies often rely on software development benchmarks for AI, which sometimes misrepresent real-world tasks, the study’s authors said.
The slowdown stemmed from developers needing to spend time going over and correcting what the AI models suggested.
“When we watched the videos, we found that the AIs made some suggestions about their work, and the suggestions were often directionally correct, but not exactly what’s needed,” Becker said.
The authors cautioned that they do not expect the slowdown to apply in other scenarios, such as for junior engineers or engineers working in codebases they aren’t familiar with.
Still, the majority of the study’s participants, as well as the study’s authors, continue to use Cursor today.
The authors believe it is because AI makes the development experience easier, and in turn, more pleasant, akin to editing an essay instead of staring at a blank page.
“Developers have goals other than completing the task as soon as possible,” Becker said. “So they’re going with this less effortful route.”
Kaspersky GReAT (Global Research and Analysis Team) experts have discovered open-source packages that download the Quasar backdoor and a stealer designed to exfiltrate cryptocurrency. The malicious packages are intended for the Cursor AI development environment, which is based on Visual Studio Code — a tool used for AI-assisted coding.
The malicious open-source packages are extensions hosted in the Open VSX repository that claim to provide support for the Solidity programming language. However, in practice, they download and execute malicious code on users’ devices.
During an incident response, a blockchain developer from Russia reached out to Kaspersky after installing one of these fake extensions on his computer, which allowed attackers to steal approximately $500,000 worth of crypto assets.
The threat actor behind these packages managed to deceive the developer by making the malicious package rank higher than the legitimate one. The attacker achieved this by artificially inflating the malicious package’s downloads count to 54,000.
After installation, the victim gained no actual functionality from the extension. Instead, malicious ScreenConnect software was installed on the computer, granting threat actors remote access to the infected device.
Using this access, they deployed the open-source Quasar backdoor along with a stealer that collects data from browsers, email clients, and crypto wallets. With these tools, the threat actors were able to obtain the developer’s wallet seed phrases and subsequently steal cryptocurrency from the accounts.
After the malicious extension downloaded by the developer was discovered and removed from the repository, the threat actor republished it and artificially inflated its installation count to a higher number – 2 million, compared to 61,000 for the legitimate package. The extension was removed from the platform following a request from Kaspersky.
“Spotting compromised open-source packages with the naked eye is becoming increasingly difficult. Threat actors are using increasingly creative tactics to deceive potential victims, even developers who have a strong understanding of cybersecurity risks — particularly those working in the blockchain development field.
As we expect adversaries to continue targeting developers, it is recommended that even experienced IT professionals deploy dedicated security solutions to safeguard sensitive data and prevent financial losses,” commented Georgy Kucherin, Security Researcher with Kaspersky’s Global Research and Analysis Team.
The threat actor behind the attack published not only malicious Solidity extensions but also another NPM package, solsafe, which also downloads ScreenConnect. A few months earlier, three additional malicious Visual Studio Code extensions were released — solaibot, among-eth, and blankebesxstnion — all of them have already been removed from the repository.
Kashifu Inuwa CCIE, the Director General of the National Information Technology Development Agency (NITDA), has reaffirmed the Federal Government’s unwavering commitment to achieving 95% digital literacy across Nigeria by the year 2030, with an ambitious milestone of 70% by 2027.
This disclosure was made in total alignment with the present administration’s priority areas of reforming the economy for sustained inclusive growth and accelerating diversification through industrialisation, digitisation, creative arts, manufacturing, and innovation.
Making this known during a collaborative meeting hosted by the Universal Basic Education Commission (UBEC), Inuwa highlighted the government’s strategic prioritisation of human capital development as central to its national transformation agenda.
“We started this journey in 2023 when President Bola Ahmed Tinubu came on board and he made it clear that economic diversification and inclusivity are part of the administration’s agenda,” he noted.
“And the president outlined this in 8 priority areas to achieve the vision, with priority number 7 specifically focused on accelerating industrialisation, digitisation, creative arts, manufacturing, and innovation,” he added.
Recognising the importance of digital fluency in achieving this agenda, he stated that NITDA is committed to investing in the digital empowerment of citizens through the development of the National Digital Literacy Framework (NDLF), a strategic blueprint aligned with international best practices.
He added that to tailor the framework to Nigeria’s specific needs, 6 core competency areas were incorporated to include device and software operations, information and data literacy, communication and collaboration, content creation, safety, and problem solving.
He explained that the framework would address all levels of digital fluency, from basic, intermediate to advanced levels, to make digital skills accessible to every Nigerian, from primary school pupils to working professionals.
According to Inuwa, despite data limitations, NITDA estimates that Nigeria’s digital literacy rate currently stands at 50%, up from 44% in 2021, based on extrapolations from the World Bank’s Better Life Report.
The NITDA DG disclosed that the agency has been working closely with the Nigerian Educational Research and Development Council (NERDC) in developing a curriculum for digital literacy, which can be infused into formal education. Stating that the visit is a continuation of NITDA’s ongoing engagements with key education stakeholders, including the Federal Ministry of Education, the National Universities Commission (NUC), and the Nigerian Educational Research and Development Council (NERDC), all aimed at advancing digital literacy across all levels of learning.
Inuwa also revealed ongoing collaborations with global platforms such as Coursera to train teachers using AI-powered lesson generation tools and provide scalable online training.
It is worth recalling that late last year, NITDA partnered with the Nasarawa State University in collaboration with CISCO in launching the Digital Learning for NSUK (DL4NSUK) initiative to enhance digital literacy in tertiary institutions, and equipping graduates with the skills needed to be digitally proficient and globally competitive.
While stressing that the entire process, from curriculum development to classroom delivery, would require a whole-of-government and whole-of-society approach, Inuwa said, “This is not a journey we can walk alone; we must bring everyone on board, education stakeholders, technology providers, state governments, and international partners.”
In response to the DG’s remarks, UBEC Executive Secretary, Hajiya Aisha Garba, confirmed that the Commission has officially received the digital literacy curriculum developed by NITDA and NERDC and has commenced internal review processes.
She acknowledged the curriculum as robust and forward-looking but stressed the need for simplification to suit early learners and teachers, citing challenges such as curriculum overload, limited teacher capacity, and inadequate infrastructure as key barriers to effective implementation.
She pledged that UBEC, in partnership with the State Universal Basic Education Board (SUBEB), will lead efforts to equip schools with computers and solar-powered infrastructure to support real learning.
“We’re committed to working with NITDA and NERDC to refine the curriculum, train teachers, and ensure effective delivery. Let us align the technical vision with grassroots realities to make a lasting impact,” she concluded.
To formalise the implementation of the meeting’s resolutions, a joint inter-agency committee was established to develop strategic plans that will ensure the effective rollout of the digital literacy initiative, to equip young Nigerians with the essential digital skills required to thrive in an increasingly dynamic and technology-driven global landscape.
