Cryptocurrency Theft and Emerging Malware Threats

Overview

Recent cybersecurity reports highlight several threats that organisations should be aware of, including software vulnerabilities, cryptocurrency theft, credential-stealing malware, ransomware and backdoors designed to remain hidden.

Key concerns include reported exploitation of an authentication bypass affecting Palo Alto Networks security products, a cryptocurrency wallet-drainer kit known as Noir, vulnerabilities affecting Adobe Experience Manager, a flaw in NVIDIA GPU drivers that may allow attackers to gain elevated privileges on Linux systems, and a WordPress backdoor designed to survive removal attempts.

Security researchers have also reported malware targeting browser sessions, developer tools and AI assistant credentials.

For organisations in Nigeria and across Africa, these developments highlight the importance of keeping systems updated, protecting user accounts, securing cloud environments and monitoring for suspicious activity. While the reports do not confirm a coordinated campaign targeting Nigeria, similar weaknesses could expose organisations to financial losses, data breaches, ransomware and service disruption.

Key Cybersecurity Threats and Their Potential Impact

Software Vulnerabilities and Unauthorised System Access

A reported vulnerability affecting Adobe Experience Manager could allow attackers to execute unauthorised commands under certain conditions. Remote code execution (RCE) vulnerabilities are particularly serious because they may allow attackers to run commands on affected systems and potentially gain access to sensitive information.

Another reported flaw, CVE-2026-47595, also known as Bad UVM, affects NVIDIA GPU drivers and may allow privilege escalation or container escape on affected Linux systems.

Potential impact: System compromise, unauthorised access, exposure of cloud workloads, service disruption and further movement across an organisation's network.

Cryptocurrency Wallet Theft Through DNS

Security research from Infoblox describes a cryptocurrency wallet-drainer kit known as Noir. It uses DNS TXT records and public DNS-over-HTTPS services to help identify attacker-controlled infrastructure.

The technique can support cryptocurrency theft by tricking users into approving malicious wallet permissions. In some cases, victims may lose funds without directly sharing their recovery phrases or private keys.

Potential impact: Cryptocurrency theft, financial losses and unauthorised transactions involving affected wallets.

Hidden Backdoors and Credential-Stealing Malware

A WordPress backdoor reported by Wordfence uses techniques designed to survive removal attempts. It may conceal unauthorised administrator accounts, steal passwords and send information to attackers.

Other reported malware targets browser sessions, developer tools and AI assistant credentials. Attackers may use stolen credentials or session data to access accounts, potentially bypassing some traditional password-based security controls.

Potential impact: Persistent unauthorised access, account takeover, compromised websites, stolen information and exposure of software development environments.

Ransomware and Remote-Access Security Risks

Reports indicate that ransomware groups Qilin and Settra have exploited an authentication bypass identified as CVE-2026-0257, affecting PAN-OS GlobalProtect and Prisma Access.

An authentication bypass can allow an attacker to gain access without completing the expected authentication process. If successfully exploited, this weakness could provide a route into an organisation's environment, allowing attackers to attempt further access, steal data or deploy ransomware.

Potential impact: Business interruption, data theft and extortion, unauthorised access to internal systems and potential disruption of critical services.

Recommendation

Organisations should consider the following actions to reduce their exposure:

• Update vulnerable systems: Identify whether affected versions of Adobe Experience Manager, NVIDIA GPU drivers, PAN-OS and Prisma Access are in use. Check official vendor advisories to confirm exposure and apply the recommended fixes.

• Secure externally accessible systems: Review internet-facing applications, remote-access services and management interfaces. Restrict access where possible and disable unnecessary services.

• Strengthen account security: Enable multi-factor authentication where supported, review privileged accounts and investigate unusual logins, unexpected VPN sessions and suspicious account changes.

• Check for malware and hidden access: Look for unfamiliar administrator accounts, unexpected file changes, suspicious processes and unusual outbound connections on websites, servers and endpoints.

• Protect cloud and development environments: Secure developer accounts, AI assistant credentials and software repositories. Review access permissions and remove unnecessary privileges.

• Monitor DNS and network activity: Investigate unusual DNS requests, suspicious DNS-over-HTTPS traffic and connections to unrecognised destinations, particularly where cryptocurrency services or compromised devices may be involved.

• Prepare for ransomware incidents: Maintain tested backups, investigate security alerts promptly and ensure incident response procedures are ready to use.

Relevance to Nigeria and Africa

Organisations across Nigeria and the wider African region should assess these developments as part of their ongoing cybersecurity risk management. Banks, fintech companies, telecommunications providers, government agencies and technology businesses may be exposed when they rely on vulnerable applications, remote-access systems, cloud services or accounts with excessive permissions.

These developments highlight the need for proactive cybersecurity measures to identify threats, address vulnerabilities and protect critical systems. Through esentry’s , vulnerability management, security monitoring and attack surface management services, organisations can gain better visibility into emerging threats, identify potential weaknesses and respond to suspicious activities. Regular security assessments and continuous monitoring can help reduce exposure, strengthen security controls and minimise the risk of data breaches, ransomware attacks and business disruption.
