Operation C-Major: Reference Collection Surges
Our tracking identified 245 new items referencing Operation C-Major over the last seven days, an increase compared to our typical weekly intake of about 55 items. These counts measure collected artifacts and mentions in the sources we monitor. They represent an increase in processing volume, not evidence of live operations, active campaigns, or intrusions. As of 2026-09-29, our analysts observed no chatter on actor-operated Telegram channels or breach forums regarding this group. This indicates an absence of data, not operational stealth.
Tracking Processes Increased Operation C-Major Artifacts and Mentions
Our tracking ingested these new items referencing Operation C-Major in the last seven days, a significant increase from the typical weekly intake. We present these figures as measurements of collected artifacts and mentions within our monitored sources. This tracking metric does not evaluate the functionality of the references or map to deployed operational infrastructure. Organizations processing this threat intelligence data must isolate the volume of ingested items from any evaluation of threat actor activity levels. We never present a cumulative all-time total as recent or current activity. This count reflects the new items processed in the preceding seven days alone, separate from previous historical collections.
Security teams monitoring automated threat intelligence platforms risk severe misallocation of resources if they conflate ingestion volume with operational activity. These counts measure collected artifacts and mentions only. They are not evidence of operations or campaigns. The jump in volume does not demonstrate intrusions or an active phase. Defenders must not classify this tracking increase as an active campaign. When our tracking shows these new items, analysts must process 190 more references than the baseline. Organizations must not conclude that the actor is active, operational, or conducting attacks based on these counts. We report only that references to the actor rose in our collection. Organizations must adjust their automated ingestion rules to categorize these items as reference material, ensuring security information and event management platforms do not trigger intrusion alerts based purely on the increased mention frequency. The sole defensive mandate stemming from this collection increase is the administrative requirement to categorize the new items accurately, maintaining clear delineation between reference artifacts and actual operational indicators.
Standing Assessment Focuses on South Asian Targets and Custom Backdoors
Our standing assessment from our actor profile predates this week and defines the group's intent as Espionage against South Asian targets. We define their capability profile as consisting of Custom backdoors, social engineering, and credential theft. We present these details as our standing assessment of the group. This assessment does not reflect behavior observed this week within the newly collected items. Security teams must decouple the standing assessment of the threat actor from the sudden increase in artifact ingestion. The tracking volume increase does not alter the fundamental capabilities defined in our actor profile.

Defenders tasked with protecting South Asian targets must align their detection engineering to these standing capabilities, instead of reacting blindly to the increased artifact mention rate. The documented capability of Custom backdoors means infrastructure administrators must scrutinize anomalous outbound connections and unverified binaries. Reliance on social engineering and credential theft requires strict validation of identity and access management controls. Organizations operating within the parameters of Espionage against South Asian targets face a specific, defined threat environment. When our tracking records this increase from the typical weekly intake, analysts at targeted organizations must process these references to refine identity monitoring rules. The new items collected in the last seven days provide a broader dataset of references, but they do not redefine the group's intent. Security operations centers must parse the typical weekly intake alongside the recent items, exclusively for relevance to Custom backdoors and credential theft affecting Espionage against South Asian targets. Any deviation from this specific threat model based solely on the artifact count introduces unacceptable diagnostic error. Organizations must mandate that all network defenders evaluate the new items specifically for social engineering components, rejecting any assumption that the increased artifact count equates to a shift away from Custom backdoors.
Complete Absence of Actor-Operated Telegram and Breach Forum Chatter
Our analysts report no chatter on actor-operated Telegram channels or breach forums in the last seven days. This finding remains constant even as our tracking ingested the new items referencing Operation C-Major. Organizations attempting to correlate the high artifact ingestion rate with the silence on external communication channels will arrive at false conclusions regarding the threat environment.

An absence of chatter or public reporting is an absence of data, not evidence of stealth. Security teams misinterpret communication voids as evidence of advanced tradecraft, but the lack of posts on breach forums provides no evidence regarding the group's methodologies. Do not interpret this silence as operational discipline. Do not interpret the lack of Telegram chatter as a covert phase. The silence recorded across these platforms over the last seven days is not preparation for anything. The collected artifacts and mentions exist independently of the actor-operated Telegram channels. Tracking new references while breach forums remain empty means our sources captured artifacts without accompanying forum discussions. Defenders must base their security posture on the collected artifacts and the standing assessment. They should treat the absence of chatter as a null value, not a variable indicating intent.
Adjusting Alerts for Operation C-Major Artifacts
- Configure alerting rules to classify the new items referencing Operation C-Major as collected artifacts and mentions, not indicators of an active phase. Security teams must tag these ingested references as structural intelligence updates to prevent automated systems from flagging the volume increase as an ongoing intrusion.
- Remove threat hunting triggers dependent on breach forum or Telegram chatter for Operation C-Major. The lack of chatter on actor-operated Telegram channels in the last seven days is an absence of data. Security teams must detach their detection workflows from expectations of public reporting or dark web announcements.
For the next 24 hours, prioritize adjusting alert rules to properly classify the 190 additional references to prevent false intrusion alarms. Removing threat hunting triggers dependent on dark web chatter over the last seven days can wait for routine administrative reviews.
