Sophos Unveils 4 New Open Artificial Intelligence Developments
Sophos, a global leader in next-generation cybersecurity, has announced four new open Artificial Intelligence (AI) developments to help broaden and sharpen the industry’s defenses against cyberattacks, including datasets, tools and methodologies designed to advance industry collaboration and cumulative innovation.
This move accelerates a key Sophos objective to open its data science breakthroughs and make the use of AI in cybersecurity more transparent, all with the aim of better protecting organizations against all forms of cybercrime.
While it is common practice to share AI methodologies and findings in other industries, cybersecurity has lagged in this effort, creating a noisy understanding of how AI truly provides protection against cyberthreats.
Sophos and its team of SophosAI data scientists are catalyzing this change toward openness, so that IT managers, security analysts, CFOs, CEOs, and others making security buying or management decisions, can discuss and assess AI benefits from a level and well-informed playing field.
Joe Levy, chief technology officer, Sophos, said “With SophosAI’s new initiative to open its research, we can help influence how AI is positioned and discussed in cybersecurity moving forward.
“Today’s cacophony of opaque or guarded claims about the capabilities or efficacy of AI in solutions makes it difficult to impossible for buyers to understand or validate these claims.
“This leads to buyer skepticism, creating headwinds to future progress at the very moment we’re starting to see great breakthroughs.
“Correcting this through external mechanisms like standards or regulation won’t happen quickly enough. Instead, it requires a grassroots effort and self-policing within our community to produce a set of practices and language that will advance the industry in a disruptive, open and transparent manner.”
It is difficult to overstate the criticality of this shift given the immense potential of how AI can benefit cybersecurity. Sophos evidence shows that defenders are increasingly facing human adversaries who are constantly upping their game, launching highly contextualized Business Email Compromise (BEC) forgery campaigns or relentlessly developing new ransomware attacks.
Scalable and effective defenses against these and most other types of cyberattacks require assistance from AI. Openness and peer review among those applying AI to address these security threats stimulate innovation and discoveries, driving the entire industry forward.
Sophos is providing datasets, tools and methodologies in four important areas:
SOREL-20M Dataset for Accelerating Malware Detection Research
SOREL-20M, a joint project between SophosAI and ReversingLabs, is a production-scale dataset containing metadata, labels and features for 20 million Windows Portable Executable files (PE).
It includes 10 million disarmed malware samples available for download for the purpose of research on feature extraction to accelerate industry-wide improvements in security.
This dataset is the first production scale malware research dataset available to the general public, with a curated and labelled set of samples and security-relevant metadata.
AI-powered Impersonation Protection Method
SophosAI’s Impersonation Protection is designed to protect against email spearphishing attacks, where influential people are impersonated to trick recipients into taking some harmful action for the benefit of the attacker.
This new protection compares the display name of inbound emails against high level executive titles – those most likely to be spoofed in a spearphishing attack, such as a CEO, CFO or president – that are unique to specific organizations and flags these messages when they appear suspicious.
Sophos has trained the AI working behind the scenes on a large sample set of millions of known attack emails. SophosAI has opened up this innovative new protection method, which it has also discussed publicly at Defcon 28 and in an Arxiv paper.
Digital Epidemiology to Determine Undetected Malware
SophosAI has also built a set of epidemiology-inspired statistical models for estimating the prevalence of malware infections in total, which enables Sophos to estimate – and in turn enabling a better chance to find – the needles in a PE file haystack.
SophosAI has pioneered and made publicly available this method that helps to determine malicious “dark matter,” malware that might be missed or wrongly classified, and “future malware” that is in development by attackers.
The model is designed to be extensible to other classes of files and information system artifacts and is also discussed in the Sophos 2021 Threat Report.
YaraML Automatic Signature Generation Tools
Signature generation for the detection of malware families is a laborious, manual process. Over the years, researchers have proposed a variety of automatic signature generation methods, most of which have not found adoption because they underperform manual methods.
SophosAI has developed a new method for automatic signature generation, called YaraML, that’s significantly different from previous options by taking an AI based approach to the problem. SophosAI directly “compiles” full-fledged, industrial strength machine learning models, the kinds used in commercial security products, into signature languages, essentially allowing AI to “write” the signatures.
This proves to be far more effective than previous approaches and represents a breakthrough for the security community. SophosAI has open-sourced YaraML.
These four advancements are the latest from SophosAI, which works creatively like a start-up incubator, but with the intellectual resources of a near billion-dollar global company, including SophosLabs, Sophos Managed Threat Response and hundreds of thousands of customers.
Another advantage is that SophosAI can add new technology directly into shipping products. This model allows Sophos to react quickly to market needs, predict where the industry must head and advance openness for greater cybersecurity industry collaboration and innovation, all of which is essential when developing defenses against fast-moving adversaries.
MTN Nigeria, has pledged the company’s renewed commitment to transparency and responsiveness in addressing customer concerns.
Karl Toriola, chief executive officer, MTN Nigeria,
Karl Toriola, chief executive officer, MTN Nigeria, stated this at the telecoms provider its first-ever Customer Engagement Day (CED) in Lagos.
Speaking during the event, Toriola fielded real-time questions from customers, responding to issues ranging from data quality to customer service gaps.
“We’ve invested heavily to build a network that delivers value for money. While data in Nigeria remains among the most affordable globally, our priority is quality and consistency that truly powers ambition. Today is about transparency: answering your questions, listening to your concerns, and showing that MTN is not just a service provider; we are a partner in your journey,” he said.
The company emphasised that the Customer Engagement Day was designed as an open forum for dialogue between MTN executives and customers.
The hybrid event, themed “We See You. We’re With You,” featured sessions on digital literacy, data usage, youth mentorship, and financial inclusion, aimed at improving subscriber experience and usage efficiency.
Ayham Moussa, chief operating officer, MTN Nigeria, in his opening remarks, highlighted the company’s long-standing connection with Nigerians, noting that its operations were built with input from ordinary citizens.
“When MTN began, it was built by people like you: engineers, entrepreneurs, everyday Nigerians. Today, we connect over 80 million people, and our focus remains simple: to stand with you in your hustle, support your ambitions, and make life easier. This journey is about listening, improving daily, and being a shield for homes and businesses across Nigeria,” he said.
A key session on Data Usage and Management offered participants practical guidance on how to manage and conserve data, with many customers raising questions about consumption patterns and transparency in billing.
Ugonwa Nwoye, chief customer relations & experience officer, MTN, stated, “We know how essential data is; it’s how we live, work, and connect. From parents streaming classes to small businesses on Zoom, we see your daily realities. That’s why we’re focused not just on providing data but on helping you use it better, with practical tools and tips that put you in control. We hear you, and we’re acting on what you’ve told us today.”
Onyinye Ikenna-Emeka, chief marketing officer of MTN Nigeria, reiterated the importance of continuous engagement: “Today has been about listening, learning, and connecting with you. We’ve heard your complaints, your ideas, and even your personal stories. From parents balancing their children’s needs to businesses working tirelessly online, be assured that we listen, we care, and we do. Your trust means everything to us, and we’re committed to turning today’s conversations into real actions.”
Ikenna-Emeka stressed that MTN Nigeria seeks to reposition itself not only as a telecom operator but also as a listening partner in the everyday lives of its subscribers.
The event also provided a platform for small businesses, young professionals, and digital creators to interact with MTN leaders during Speed Mentorship sessions, where they shared their goals and received guidance on navigating the digital economy, technology adoption, and entrepreneurial strategy.
Visitors engaged with various thematic lounges, including MoMo PSB, MTN’s fintech subsidiary, where tools for financial inclusion were showcased.
Other activities included a digital skills academy, interactive tech demonstrations, and a startup pitch challenge, reflecting MTN’s efforts to align services with evolving customer needs.
Airtel Africa Plc increased its capital expenditure in Nigeria to $39m in the second quarter of 2025, up 1.7 per cent from $38m in the same period last year.
According to the company’s financial statement the marginal increase highlights Airtel’s continued investment in its largest and most strategic market, despite a broader slowdown in group-level capital spending this quarter.
The Punch newspaper reported that the increase in capital spending by Airtel comes at a time when telecom subscribers are expecting tangible improvements in service quality, following a 50 per cent tariff adjustment approved by the Nigerian Communications Commission earlier this year.
It added that Telcos have begun to show signs of commitment to network upgrades, bolstered by the recent delivery of telecom equipment valued at $1bn.
“In Nigeria, capital expenditure for the quarter ended 30 June 2025 was $39m, compared to $38m in the same period last year,”.
According to the statement, the Group-wide capital expenditure stood at $121m in the three months ended June 30, representing a decline from the previous year, which the company attributed to timing differences in project execution.
However, Airtel maintained its full-year capex guidance at between $725m and $750m, indicating that more spending is anticipated in the coming quarters.
Capital expenditure, or Capex, refers to the funds used by a company to acquire or upgrade physical assets such as network towers, fibre infrastructure, and IT systems.
In Nigeria, the $39m spent during the quarter was likely directed toward expanding and modernising the operator’s mobile and broadband networks, enhancing service coverage and capacity in urban and rural areas.
MTN Nigeria Communications Plc has achieved a historic milestone, becoming the first listed company on the Nigerian Exchange Limited (NGX) to reach a market capitalization of ₦10 trillion, as its share price closed at ₦480 on Friday, August 1, 2025.
The telecommunications giant’s shares gained ₦8 or 1.69% during Friday’s trading session, pushing the company’s market value past the ₦10 trillion threshold.
This remarkable achievement comes just two days after MTN Nigeria released its stellar half-year 2025 financial results on Wednesday, which showed exceptional performance across all key metrics.
The timing is not surprising based on what was said in the company’s H1 results, which revealed a dramatic turnaround from losses to profitability.
The telecoms operator reported service revenue growth of 54.6% to ₦2.4 trillion, while EBITDA surged by 119.5% to ₦1.2 trillion with margins expanding significantly to 50.6%.
Most importantly, the company achieved a profit after tax of ₦414.9 billion, marking a stunning recovery from the loss of ₦519.1 billion recorded in the same period last year.
Speaking on the H1 2025 results that have driven investor confidence, Karl Toriola, CEO, MTN Nigeria, said: “We are excited by the progress made in the first half of 2025, reflecting the successful execution of the strategic priorities we previously communicated to the market.”
Toriola emphasized the company’s strong operational momentum, stating: “Building on the momentum from the first quarter, we delivered strong growth in service revenue for the period under review. This was driven by robust demand for our services, proactive customer value management and price adjustments, mainly in Q2.”
The CEO’s confidence in the company’s trajectory was evident in his commentary about future prospects.
“In light of the strong momentum in our business, we have upgraded our FY 2025 and medium-term guidance and we remain firmly on track to restore our balance sheet to a positive net asset position by the end of Q3,” Toriola declared.
This optimistic outlook, backed by upgraded financial guidance targeting service revenue growth of “at least low-50%” and EBITDA margin of “at least low-50%” for FY 2025, has clearly resonated with investors.
Toriola highlighted improving operating conditions that have supported the company’s performance: “The macroeconomic conditions in Nigeria showed notable improvements in the period under review, including a relatively stable naira, improved foreign exchange (forex) liquidity and easing inflationary pressures.”
He noted that “this backdrop helped to enable our improved business performance and set a more supportive context for increased long-term investments.”
The ₦10 trillion market cap milestone represents extraordinary value creation for shareholders.
