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.

Huawei Unveils AI Computing System to Challenge Nvidia’s Flagship Product

China’s Huawei Technologies unveiled an AI computing system on Saturday that an industry expert said rivals Nvidia’s most advanced product, as the company aims to expand its footprint in the country’s booming AI sector.
The CloudMatrix 384 system made its public debut at the World Artificial Intelligence Conference (WAIC), a three-day event in Shanghai, attracting a large crowd to Huawei’s booth with its showcase of cutting-edge AI innovations.
The system has attracted significant interest from the global AI community since Huawei (HWT.UL) first introduced it in April. Industry analysts see it as a direct challenger to Nvidia’s GB200 NVL72, the most advanced system-level offering currently available from the U.S. chipmaker.
In an April article, Dylan Patel, founder of semiconductor research firm SemiAnalysis, stated that Huawei now possesses AI system capabilities that could surpass those of Nvidia.
Huawei staff at its WAIC booth declined to comment when asked to introduce the CloudMatrix 384 system.
A spokesperson for Huawei did not respond to questions.
Huawei has become widely regarded as China’s most promising domestic supplier of chips essential for AI development, even though the company faces U.S. export restrictions.
Nvidia CEO, Jensen Huang told Bloomberg in May that Huawei had been “moving quite fast” and named the CloudMatrix as an example.
The CloudMatrix 384 system features 384 of Huawei’s latest 910C chips and, according to SemiAnalysis, surpasses Nvidia’s GB200 NVL72 in certain performance metrics, despite the latter using 72 B200 chips.
SemiAnalysis attributes this performance advantage to Huawei’s strong system design, which offsets the lower power of individual chips by leveraging a greater number of them and incorporating system-level innovations.
Huawei describes the system as utilizing a “supernode” architecture that enables ultra-high-speed interconnectivity between chips.
In June, Zhang Pingan, CEO, Huawei Cloud confirmed that the CloudMatrix 384 was already operational on Huawei’s cloud platform.

Microsoft Servers Hacked by Chinese Groups

Chinese “threat actors” have hacked Microsoft’s SharePoint document software servers and targeted the data of the businesses using it, the firm has said.
China state-backed Linen Typhoon and Violet Typhoon as well as China-based Storm-2603 were said to have “exploited vulnerabilities” in on-premises SharePoint servers, the kind used by firms, but not in its cloud-based service.
The US tech giant has released security updates in response and has advised all on-premises SharePoint server customers to install them.
“Investigations into other actors also using these exploits are still ongoing,” Microsoft said in a statement.
The firm said it had “high confidence” the hackers would continue to target systems which have not installed its security updates.
It added that it would update its website blog with more information as its investigation continues.
Microsoft said it had observed attacks in which hackers had sent a request to a SharePoint server “enabling the theft of the key material by threat actors”.
Charles Carmakal, chief technology officer at Mandiant Consulting firm, a division of Google Cloud, told reporter, it was “aware of several victims in several different sectors across a number of global geographies”.
Carmakal said it appeared that governments and businesses that use SharePoint on their sites were the primary target.
A number of adversaries who stole material encoded by cryptography were then able to regain ongoing access to the victims’ SharePoint data, he said.
“This was exploited in a very broad way, very opportunistically before a patch was made available. That’s why this is significant,” Carmakal said.
Carmakal said the “China-nexus actor” was deploying techniques similar to previous campaigns associated with Beijing.
Microsoft said Linen Typhoon had “focused on stealing intellectual property, primarily targeting organizations related to government, defence, strategic planning, and human rights” for 13 years.
It added that Violet Typhoon had been “dedicated to espionage”, primarily targeting former government and military staff, non-governmental organizations, think tanks, higher education, the media, the financial sector and the health sector in the US, Europe, and East Asia.
Meanwhile, Storm-2603 was “assessed with medium confidence to be a China-based threat actor”.
