A new report by Sophos, ybersecurity firm, has said that attackers primarily gained initial network access—56 per cent of all MDR and IR cases—by exploiting external remote services like firewalls and VPNs using valid credentials.

Cyberattacks: ‘56 Percent of Cases Stem from Existing Logins

The 2025 Sophos Active Adversary Report details attacker behavior and techniques from over 400 Managed Detection and Response [MDR] and Incident Response [IR] cases in 2024.

According to the report, the combination of external remote services and valid accounts align with the top root causes of attacks.

For the second year in row, compromised credentials were the number one root cause of attacks [41% of cases]. This was followed by exploited vulnerabilities [21.79%] and brute force attacks [21.07%].

When analysing MDR and IR investigations, the Sophos X-Ops team looked specifically at ransomware, data exfiltration, and data extortion cases to identify how fast attackers progressed through the stages of an attack within an organisation.

In those three types of cases, the median time between the start of an attack and exfiltration was only 72.98 hours [3.04 days]. Furthermore, there was only a median of 2.7 hours from exfiltration to attack detection.

“Passive security is no longer enough. While prevention is essential, rapid response is critical. Organisations must actively monitor networks and act swiftly against observed telemetry.

Coordinated attacks by motivated adversaries require a coordinated defense. “For many organisations, that means combining business-specific knowledge with expert-led detection and response.

Our report confirms that organizations with proactive monitoring detect attacks faster and experience better outcomes,” said John Shier, field CISO.

The 2025 Sophos Active Adversary Report further reveals that attackers can move quickly, with a median of just 11 hours between initial access and a breach attempt on Active Directory, a critical asset in Windows environments.

Akira emerged as the most prevalent ransomware group in 2024, followed by Fog and LockBit, the latter still active despite a major takedown.

Attack detection has improved overall, with dwell time—the time attackers remain undetected—dropping from four days to just two, thanks largely to the inclusion of MDR (Managed Detection and Response) cases.

Dwell time varied depending on the type of case: it held steady at 4 days for ransomware and 11.5 days for non-ransomware cases in incident response (IR) investigations.

In contrast, MDR cases showed much faster response times—3 days for ransomware and just 1 day for non-ransom – ware attacks.

The report also highlights that 83% of ransomware deployments occurred outside local business hours, showing attackers favor overnight activity.

Additionally, Remote Desktop Protocol (RDP) was exploited in 84% of cases, making it the most commonly abused Microsoft tool.

To strengthen their cybersecurity posture, Sophos advises organizations to take several key steps.

First, they should close any exposed Remote Desktop Protocol (RDP) ports and implement phishing-resistant multifactor authentication (MFA) wherever feasible to reduce unauthorized access risks.

Additionally, companies should prioritize timely patching of vulnerable systems, especially those exposed to the internet. Deploying Endpoint Detection and Response (EDR) or Managed Detection and Response (MDR) solutions with 24/7 monitoring is crucial.

Finally, having a well-defined incident response plan—and regularly testing it through simulations or tabletop exercises—can greatly improve preparedness for potential attacks.

Microsoft is stepping up its push to expand artificial-intelligence adoption across Africa as competition intensifies with Chinas DeepSeek for influence in one of the worlds youngest and fastest-growing digital markets.

Microsoft Expands Africa AI Push while DeepSeek Gains Users

The company plans to train 3 million Africans on its AI technologies this year through partnerships with schools, universities and other institutions, with a focus on South Africa, Kenya, Nigeria and Morocco.

The effort reflects Microsofts broader attempt to accelerate adoption of its AI ecosystem across emerging markets where developers and enterprises are increasingly experimenting with generative AI tools.

Alongside the training initiative, Microsoft is working with MTN Group (MTNOY), Africas largest telecommunications company, to distribute Microsoft 365 and its Copilot digital assistant to about 300 million subscribers.

The Elevate program is designed to expand AI literacy and reduce cost barriers that might otherwise limit adoption, according to regional leadership.

The push comes as Chinese technology firms expand their footprint across the continent, with DeepSeeks open-source models accounting for roughly 11% to 14% of chatbot use in several African markets and reaching about 20% in countries such as Ethiopia and Zimbabwe following investments tied to digital infrastructure and telecom networks.

Microsoft is also increasing its infrastructure investment in the region.

In South Africa, the company plans to invest 5.4 billion rand, or about $330 million, to expand its cloud and AI capacity by the end of next year, while it is also exploring plans for a geothermal-powered data center in Kenya.

Early corporate adoption is emerging across the continent, with South African grocer Spar Group using Copilot in ways that save more than 700 employee hours annually and Nigerias Access Holdings integrating AI into daily workflows.

Regional leadership has suggested broader AI adoption could potentially contribute up to $1.5 trillion to Africas gross domestic product by 2030 if governments and businesses continue investing in digital infrastructure and AI skills.

Kaspersky Uncovers a New Android Malware Campaign Disguised as Starlink Application

Published

on

Kindly share this post

Kaspersky Global Research and Analysis Team (GReAT) has uncovered a new Android malware campaign in which cybercriminals distributed the BeatBanker Trojan under the guise of the Starlink application for Android.

Threat actors primarily target users from Brazil; nevertheless, Kaspersky experts don’t rule out that users from other countries may also face this threat.

The Trojan employs a Monero cryptocurrency miner and additionally installs a BTMOB remote administration tool (RAT) on the infected devices. To maintain its persistence, BeatBanker uses an uncommon mechanism involving a nearly inaudible looped audio file.

“At first we saw BeatBanker being distributed under the guise of a public services app; it installed a banking Trojan in addition to a cryptocurrency miner. However, our recent detection efforts uncovered a new campaign with another BeatBanker variant that deploys the BTMOB RAT instead of the banker module.

The attackers appear to be using a fresh lure with the Starlink app to reach more victims from different countries. Therefore, it is important for users to stay vigilant and use advanced solutions to protect their smartphones,” comments Fabio Assolini, Head of the Americas & Europe units at Kaspersky GReAT.

Initial vector of infection

Kaspersky experts believe that cybercriminals distribute a fake Starlink application containing the BeatBanker Trojan through phishing pages that mimic the Google Play Store. After execution on a compromised device, the Trojan displays a user interface that also mimics Google Play. Cybercriminals trick victims into granting installation permissions, thus allowing the download of additional hidden malicious payloads.

Crypto mining and BTMOB RAT module

When a user clicks UPDATE on the fake Google Play page, a Monero cryptocurrency miner deploys. BeatBanker monitors battery percentage and the temperature of an infected smartphone, as well as user activity after which a hidden cryptocurrency miner is started or stopped.

The Android Trojan also installs a BTMOB RAT on the compromised device. BTMOB enables full remote control and is sold as Malware-as-a-Service.

It is capable of automatic granting of permissions, hide system notifications and has mechanisms designed to capture screen lock credentials, including PINs, patterns and passwords on compromised devices. The malware also gives cybercriminals access to the front and rear cameras, GPS location monitoring and constant collection of sensitive data.

To ensure persistence and hinder uninstallation, BeatBanker maintains a fixed notification in the foreground and activates a foreground service with silent media playback. This tactic is designed to prevent the operating system from removing the malicious process.

Kaspersky’s products detect this threat as HEUR:Trojan-Dropper.AndroidOS.BeatBanker and HEUR:Trojan-Dropper.AndroidOS.Banker.*.

                                                                                        By Shameel Joosub

For centuries, Africa has powered global economic growth through its resources, labour, and human potential, yet too little of that prosperity has been realised on the continent itself. Today, artificial intelligence presents a rare opportunity to change that trajectory.

How Africa Can Turn the AI Wave into Inclusive Growth

As the global economic order undergoes its most significant transformation since the end of the Second World War, Africa stands at a decisive inflection point.

With the world’s youngest population, rapidly expanding digital adoption, and vast untapped potential, Africa is uniquely positioned not just to participate in the AI era, but to help shape it.

Realising this opportunity, however, will require deliberate investment, enabling regulation, and a commitment to ensuring that the benefits of AI reach all 1.5 billion people across the continent.

When I reflect on AI, what strikes me most is that it is enabled by humanity.

Intelligence is fundamentally human, and AI is an extraordinary amplifier of human creativity and capability.

It is not about replacing people. It is about empowering them to do more, faster, and better.

While this progress is remarkable, our responsibility as African businesses is to extend these capabilities beyond our corporate walls so that AI can unlock Africa’s underutilised potential and drive inclusive growth.

Unlocking Africa’s Potential Across Industries

As a purpose-led African connectivity and digital services company serving 223.2 million customers across South Africa, the DRC, Egypt, Ethiopia, Kenya, Lesotho, Mozambique, and Tanzania, Vodacom has invested strategically in AI across multiple sectors.

Our mobile networks reach a population of 588 million people. That reach must translate into opportunity.

Consider agriculture. One of our subsidiary companies, Mezzanine, leverages AI to unlock previously invisible insights into soil composition, empowering farmers to make data-driven decisions that improve crop yields and profitability.

When farmers thrive, food security strengthens and rural communities prosper. That is inclusive growth in action.

In financial services, AI is strengthening trust and security. In Kenya, Graph Network Analytics enhances M-Pesa fraud detection by mapping money movements in real time, helping protect more than 37 million customers who rely on the service in their daily lives.

As criminals target digital payment platforms, AI helps predict and prevent fraud scenarios, including SIM swap fraud and identity theft.

AI is also supporting national infrastructure. In South Africa, connectivity and IoT solutions monitor coal transport in real time from pit to port to power station.

This improves operational efficiency and supports energy security, addressing critical infrastructure challenges that have constrained economic growth.

These are not isolated examples. They represent a broader truth. Technology delivers its greatest value when it solves real problems for real people.

The Infrastructure Imperative: Modernising Regulation

Yet none of this is possible without one fundamental prerequisite: connectivity. Connectivity requires sustained investment in infrastructure, supportive policy environments, and regulatory frameworks that enable innovation.

If Africa is serious about universal access, modern and enabling regulation is essential. Spectrum licensing must be efficient and predictable. Infrastructure sharing must be supported. Universal service funds must be effectively deployed. Administrative barriers to infrastructure rollout must be reduced. Cloud and data platforms, which power AI capabilities, must be supported through enabling policy environments. These are not peripheral issues. They are fundamental to accelerating Africa’s digital and economic transformation.

These challenges represent only a portion of the regulatory barriers that must be addressed to deliver affordable, reliable connectivity to all Africans.

Pan-African Coordination: Our Collective Responsibility

Africa’s greatest advantage is its youth, but demographics alone will not deliver growth. To realise this potential, we must actively skill up young people in our schools and universities so they can take full advantage of an AI-driven future.

That requires modernising education curricula to embed AI literacy, data capability and practical problem-solving at scale. Companies like Vodacom are investing in digital skills development, but unlocking Africa’s potential will require coordinated action across government, academia and industry.

This is why governments and intergovernmental institutions such as the African Development Bank Group, the African Union, SADC, ECOWAS, and other regional bodies play a critical role in harmonising regulatory frameworks across the continent. Greater coordination can accelerate investment, enable scale, and support the development of an integrated digital economy.

Pan-African alignment of telecommunications regulation is not merely a technical objective. It is essential to unlocking inclusive growth and ensuring that Africa can compete effectively in the global digital economy.

Our Moment

Africa has long contributed to global progress. In the AI era, it has the opportunity to define its own future as a creator of innovation, productivity, and inclusive growth. The foundations are already in place. Our young population, expanding connectivity, and accelerating digital adoption position the continent to lead in ways that were not previously possible.

But this outcome is not guaranteed. It depends on the choices we make now. By modernising regulation, investing in connectivity as foundational infrastructure, and ensuring that AI empowers individuals, businesses, and communities, Africa can secure its place as a central force in the global digital economy.

 

That is the Africa I believe in. That is the Africa we are building at Vodacom, connecting people, enabling opportunity, and ensuring that technology serves the progress of society as a whole
