A threat group dubbed NoisyBear has been targeting Kazakhstan's oil and gas sector since April 2025. The campaign focuses on KazMunaiGas employees, using spear-phishing emails with malicious attachments. The infection chain involves a ZIP file containing a malicious LNK file and decoy document, which downloads a batch script, leading to PowerShell loaders (DOWNSHELL) and ultimately a malicious DLL implant. The threat actor uses various techniques including AMSI bypass, process injection, and reflective DLL loading. Infrastructure analysis reveals the use of sanctioned hosting providers and open-source post-exploitation tools. The group is believed to be of Russian origin based on language artifacts and targeting patterns.

A threat group dubbed NoisyBear has been targeting Kazakhstan's oil and gas sector since April 2025, particularly focusing on KazMunaiGas employees. The campaign uses spear-phishing emails with malicious ZIP attachments containing LNK files. These files download batch scripts, which in turn retrieve PowerShell loaders dubbed DOWNSHELL. The infection chain progresses through multiple stages, ultimately leading to the deployment of a malicious DLL implant. The threat actor employs various techniques to evade detection, including AMSI bypass and reflective DLL injection. The infrastructure used by NoisyBear is hosted on sanctioned web services, and the group is suspected to be of Russian origin based on language artifacts and targeting patterns.

A new ransomware strain called 'Blue Locker' is targeting Pakistan's oil and gas sector, particularly affecting Pakistan Petroleum Limited. The National Cyber Emergency Response Team (NCERT) has issued warnings to 39 key ministries and institutions about this severe threat. The ransomware, which shares similarities with the Shinra malware family, encrypts files and demands ransom payments. It uses a combination of AES and RSA encryption algorithms and is distributed through phishing emails and malicious attachments. The attack coincided with Pakistan's Independence Day, suggesting possible nation-state involvement rather than traditional cybercriminal activity. NCERT has recommended strengthening cybersecurity measures, including multi-factor authentication, email filtering, and employee training. The incident highlights vulnerabilities in Pakistan's government IT infrastructure and the need for a more proactive cybersecurity approach.
