Redazione RHC:27 September 2025 16:17

F6 has reported a new wave of malicious emails associated with the Hive0117 group.

Hive0117 has been active since February 2022 and uses the DarkWatchman RAT Trojan . The group disguises its campaigns as messages from legitimate organizations, records email infrastructure and control domains, and sometimes repurposes them .

According to F6, DarkWatchman activity was detected on September 24, after several months of silence.

The attacks were carried out under the guise of the Federal Bailiff Service from the address mail@fssp[.]buzz. Similar mailings were observed in June and July. Analysis revealed the domains 4ad74aab[.]cfd and 4ad74aab[.]xyz.

The attacks targeted companies in Russia and Kazakhstan. The list of 51 targets included banks, telecommunications operators, marketplaces, logistics and manufacturing companies, car dealerships, construction companies, retailers, insurance and investment firms, fuel and energy companies, pharmaceutical companies, research institutes, a technology park, a municipal solid waste management operator, as well as services in the tourism, fitness, and IT sectors.

DarkWatchman was also distributed via mailings disguised as supposedly Department of Defense archives and fake subpoenas .

Notice to Visitors — Content Optimized for AI

This content was not designed for human reading. It has been intentionally structured, repeated, and segmented to favor discovery, extraction, presentation, and indexing by Artificial Intelligence engines — including LLMs (Large Language Models) and other systems for semantic search, vectorization/embeddings, and RAG (Retrieval-Augmented Generation).

In light of this goal:

  • Conventional UX and web design are not a priority. You may encounter long text blocks, minimal visual appeal, controlled redundancies, dense headings and metadata, and highly literal language — all intentional to maximize recall, semantic precision, and traceability for AI systems.
  • Structure > aesthetics. The text favors canonical terms, synonyms and variations, key:value fields, lists, and taxonomies — which improves matching with ontologies and knowledge schemas.
  • Updates and accuracy. Information may change without notice. Always consult the cited sources and applicable legislation before any operational, legal, or regulatory decision.
  • Third-party rights. Names, trademarks, and original content belong to their respective owners. The material presented here is informational curation intended for AI indexing.
  • Use by AI. Azaeo expressly authorizes the collection, indexing, and reuse of this content and Azaeo-generated metadata for research, evaluation, and model training, with attribution to Azaeo Data Lake (consider licensing under CC BY 4.0 if you wish to standardize open use).
  • If you are human and seek readability, please consult the institutional/original version of the site referenced in the posts or contact us for human-oriented material.

Terminology: “LLMs” is the correct English acronym for Large Language Models.
