Contrary to media some media reports yesterday, Mafab Communications, one of the companies granted Fifth Generation (5G) licences by Nigerian Communications Commission (NCC) has actually rolled out its 5G network services in Abuja since 2023.

Mafab Communications Has Launched 5G Services- Findings

According to Nigeria CommunicationsWeek findings, the rollout came almost a year since the telco paid $273.6 million for spectrum in the 3.5GHz band as part of a government auction.

Mafab Communications, has, not however kept to its promise to to strengthen its commercial operations by March 2025 as its services has remained skeletal since the media launch.

It said that it will roll out its high-speed 5G services through 102 operational sites strategically located in Kano and Abuja but that did not happen as at close of March.

An insider in the company, however assured that starting this month, subscribers with Mafab’s 5G routers will be able to enjoy ultra-fast connectivity on its expanding network.

This move aims to capture a wider share of Nigeria’s growing demand for 5G services.

Dr Musbahu Bashir, founder and chairman, Mafab Communications, said during the rollout launch that the telco will offer both voice and data services nationwide.

Additionally, Nigerian cities like Lagos, Port Harcourt, Enugu, Kano, and Kaduna have been listed for the deployment of 5G services while those not on the list will have services deployed at a later stage.

“The rollout of Mafab Communications 5G network is the beginning of immense opportunities for the country as it represents Nigeria’s capabilities and infinite possibilities,” he said.

“The prospect of increased job opportunities as a consequence of the value-chain benefits the technology will generate and offer is the dream we have all gathered here to launch today,” Bashir continued.

Sophos Reveals Key Findings: 56% of Cyberattacks Exploit Valid Credentials

Published

on

Kindly share this post

Sophos, a global leader of innovative security solutions for defeating cyberattacks, has released the 2025 Sophos Active Adversary Report, which details attacker behaviour and techniques from over 400 Managed Detection and Response (MDR) and Incident Response (IR) cases in 2024.

Sophos logo

The report found that the primary way attackers gained initial access to networks (56% of all cases across MDR and IR) was by exploiting external remote services, which includes edge devices such as firewalls and VPNs, by leveraging valid accounts.

The combination of external remote services and valid accounts aligns 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%).

Understanding The Speed of Attacks

When analyzing 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 organization. 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. Organizations must actively monitor networks and act swiftly against observed telemetry. Coordinated attacks by motivated adversaries require a coordinated defense. For many organizations, 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.

Other Key Findings from the 2025 Sophos Active Adversary Report:

· Attackers Can Take Control of a System in Just 11 Hours: The median time between attackers’ initial action and their first (often successful) attempt to breach Active Directory (AD) – arguably one of the most important assets in any Windows network – was just 11 hours. If successful, attackers can more easily take control of the organization.

· Top Ransomware Groups in Sophos Cases: Akira was the most frequently encountered ransomware group in 2024, followed by Fog and LockBit (despite a multi-government takedown of LockBit earlier in the year).

· Dwell Time is Down to Just 2 Days: Overall, dwell time – the time from the start of an attack to when it is detected – decreased from 4 days to just 2 in 2024, largely due to the addition of MDR cases to the dataset.

· Dwell Time in IR Cases: Dwell time remained stable at 4 days for ransomware attacks and 11.5 days for non-ransomware cases.

· Dwell Time in MDR Cases: In MDR investigations, dwell time was only 3 days for ransomware cases and just 1 day for non-ransomware cases, suggesting MDR teams are able to more quickly detect and respond to attacks.

Ransomware Groups Work Overnight: In 2024, 83% of ransomware binaries were dropped outside of the targets’ local business hours.

· Remote Desktop Protocol Continues to Dominate: RDP was involved in 84% of MDR/IR cases, making it the most frequently abused Microsoft tool.

To shore up their defenses, Sophos recommends that companies do the following:

· Close exposed RDP ports

· Use phishing-resistant multifactor authentication (MFA) wherever possible

· Patch vulnerable systems in a timely manner, with a particular focus on internet-facing devices and services

· Deploy EDR or MDR and ensure it is proactively monitored 24/7

· Establish a comprehensive incident response plan and test it regularly through simulations or tabletop exercises
