Nigerian Communication Commission (NCC), said it curbed unauthorized transmission on the 5.4GHz Frequency Band.

NCC Stops Unauthorised Transmission on 5.4GHz Frequency Band

The 5.4 GHz band is designated for unshared, coordinated and protected use of wireless access systems (WAS).

According to NCC, it visited the site of Trefoil Network Limited operation in Abuja over unauthorised transmission on the 5.4GHz frequency band.

The commission explained that after the company made a presentation in respect of its application for a regional Private Network Link (PNL) license which it intended to deploy using the unlicensed 5GHz band, it found out that Trefoil was transmitting on the licensed 5.4GHz band for its Internet service provision.

”A pre-enforcement notice was sent to Trefoil accordingly.

”In its response letter dated March 5th, 2019, it informed the Commission that it had vacated and desisted from the licensable portion of the band.”

The Enforcement Unit of the Commission also received a referral from Spectrum Administration Department regarding a complaint of frequency interference assigned to ipNX Nigeria Limited on the 5.4GHz band affecting its services in Abuja, Kano, Lagos Ibadan and Port Harcourt.

However, the commission issued pre-enforcement notices to the affected companies to vacate the frequency band on or before March 10, 2019.

”Following the notices, while some companies notified the Commission of their compliance, others failed to respond.

”Consequently, the Commission carried out an enforcement action against the illegal usage of 5.4GHz in Kano on March 12th, 2019 and in Lagos on March 26th, 2019 respectively to verify the claims by the companies/operators.

”The Companies visited in Kano were found to have vacated the 5.4GHz band that were causing interference.

”Enforcement was effected against three (3) companies found to be in violation in Lagos after the enforcement exercise undertaken for that purpose.

”Recovered items included 2 SDR Radio antennas and 2 Power over Ethernet (PoE) Power Packs in the operation and thereby enabled the successful shut down of the offending radios.”

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
