BlueLocker Ransomware Surge in Pakistan Triggers “Extreme” Warning from National CERT
Islamabad — Pakistan is facing a sharp rise in ransomware attacks, particularly involving the malicious “BlueLocker” malware, prompting the National Cyber Emergency Response Team (National CERT) to release a high-priority cybersecurity advisory.
According to the warning, cybercriminals are increasingly using unverified platforms and infected files to deploy BlueLocker, aiming to extort digital ransom from targeted organizations. These attacks can halt business operations entirely and cause permanent loss of critical data.
How BlueLocker Operates
National CERT reports that BlueLocker is highly dangerous due to its ability to:
-
Disable antivirus software and other security measures.
-
Spread across entire networks rapidly.
-
Steal sensitive information before locking systems.
The malware is being distributed through trojanized downloads, phishing emails, unsecured file-sharing services, and compromised websites. Its main targets include Windows-based desktops, laptops, servers, networks, and cloud storage systems. The threat level is officially marked as “extremely high.”
Recommended Security Measures
To combat the growing threat, National CERT advises:
-
Implementing multi-factor authentication for all systems.
-
Enabling advanced email filtering for suspicious links and attachments.
-
Disconnecting shared drives and backups immediately in case of an attack, keeping them offline and secure.
-
Preserving forensic evidence to aid in investigations.
-
Strengthening preventive cybersecurity systems.
Employee Awareness and Vigilance
Organizations are urged to train their staff to recognize suspicious emails, links, and attachments. They must also ensure systems are updated regularly and avoid downloading content from unverified sources, as these remain the most common entry points for ransomware.
Government Action and Alerts
National CERT’s Director General Dr. Haider Abbas has issued formal warnings to 39 key ministries and institutions, including:
-
Cabinet Division, Ministry of Interior, Ministry of Foreign Affairs
-
NECTA, FIA, National Security Division, Establishment Division
-
Election Commission, National Assembly, National IT Board
-
PEMRA, NDMA, OGRA, FBR, and ministries of Finance, Communications, Privatisation, Religious Affairs, IT & Telecom, Law and Justice, Railways, Commerce, Environment, Industries & Production, and Science & Technology
All have been urged to take immediate preventive action to protect against BlueLocker ransomware and other emerging cyber threats.
