- ESET researchers have shown that Iran-Uitgevelde-Beschedgroep Bladedfeline was aimed at Kurdish and Iraqi government officials with a range of malignant tools that have been discovered within their systems.
- ESET discovered and analyzed two inverted tunnels (Laret and Pinar), a back door (whisper), an evil IIS module (Primecache) and various additional tools.
- With great confidence, ESET researchers assess that Bladedfeline is a subgroup within Iran-uttered toingle, such as the first implants used there, can be traced back to Oilrig-Groep.
- Bladedfeline has already endangered the Kurdish diplomatic officers with the Shahmaran Signature Backdoor of the group in 2023.
Montreal and Bratislava, Slovakia, 5 June 2025 (Globe Nieuwswire)-ESET researchers, according to the Iran-Uitdelveldeldeldeldfeline threat group, focused on the Kurdish and Iraqi government officials in a recent cyber-desspionage campaign. The group has used a series of malignant tools in the compromised systems, indicating a continuous effort to maintain and expand access to high -ranking officials and government organizations in Iraq and the Kurdish region. The newest campaign emphasizes the evolving possibilities of Bladedfeline, with two tunneling tools (Laret and Pinar), various additional tools and, in particular an adapted backdoor Whisper and a Malicious Internet Information Services (IIS) module Primecache, both identified and mentioned by ESET.
Whisper logs to a compromised webmail account on a Microsoft Exchange Server and uses it to communicate with the attackers via E -mail attachments. Primecache also serves as a back door: it is a malignant IIS module. Primecache also shows similarities with the RDAT door used by Oilrig Advanced Persistente Threat (APT) group.
Based on these code agreements, as well as on further evidence that this blog post is presented, ESET assesses that Bladedfeline is a very likely subgroup of Oilrig, an Iran-Uitgewelde APT group that goes back and companies in the Middle East. The first implants in the latest campaign can be taken back to Oilrig. These tools reflect the strategic focus of the group on persistence and stealth within targeted networks.
Bladeedfeline has consistently worked to maintain illegal access to Kurdish diplomatic officials, while at the same time using a regional telecommunications provider in Uzbekistan, and to develop and maintain access to civil servants in the Government of Iraq.
ESET research assesses that Bladedfeline focuses on the Kurdish and Iraqi governments for cyberspionage purposes, with a view to maintaining strategic access to the computers of high-ranking officials in both government institutions. The Kurdish diplomatic relationship with Western countries, in combination with the oil reserves in the Kurdistan region, makes it a tempting target for Iran-Uitgevelkelde threat actors to spy and possibly manipulate. In Iraq, these threat actors probably try to prevent the influence of Western governments after the American invasion and occupation of the country.
In 2023, ESET research discovered that Bladedfeline focused on Kurdish diplomatic officials with the Shahmaran and previously reported on his activities in ESET APT activities reports. The group has been active since at least 2017, when the civil servants within the regional government of Kurdistan endangered, but is not the only subgroup of Oilrig who monitors ESET research. ESET has followed Lyceum, also known as Hexaan or Storm-0133, as another subgroup of Oilrig. Lyceum focuses on focusing on various Israeli organizations, including government and local government entities and healthcare organizations.
ESET expects Bladedfeline to continue to exist with the development of implants to maintain and expand access within the compromised victim who is set for cyberspionage.
