FULL STORY ======================================================================Ink Dragon campaign breaches European governments by exploiting misconfigured IIS and SharePoint servers The group uses its FinalDraft backdoor to blend C2 traffic with normal Microsoft cloud activity Dozens of government and telecom entities worldwide were turned into relay nodes for further operations

Ink Dragon, a known Chinese state-sponsored threat actor, has extended its reach into European governments, using misconfigured devices for initial entry, and establishing persistence by blending with regular traffic, experts have warned.

A report from cybersecurity researchers Check Point Software claims the attackers are using Microsoft IIS and SharePoint servers as relay nodes for future operations.

"This stage is typically characterized by low noise and spreads through infrastructure that shares the same credentials or management patterns,"
Check Point's researchers said. FinalDraft updates

For initial access, the group does not abuse zero-day, or other vulnerabilities, as that would most likely trigger security solutions and alarms. Instead, they probe the servers for weaknesses and misconfigurations, successfully flying under the radar.

After finding an account with domain-level access, the group expands to other systems, installs backdoors and other malware, establishes long-term access and exfiltrates sensitive data.

In their toolbox, Ink Dragon has a backdoor called FinalDraft, which was recently updated to blend with common Microsoft cloud activity. It was said. Its C2 traffic is usually left in the drafts folder of an email account.
Whats also interesting is that the malware only works during regular business hours, when the traffic is greater and when its more difficult to spot any suspicious activity.

Finally, once the attackers secure persistent access to compromised servers, they repurpose the victims infrastructure by installing custom IIS-based modules on internet-facing systems, turning them into relay points for their malicious operations.

Check Point could not name the victims, for obvious reasons, but it did
reveal several dozens entities were hit, including government organizations and telecommunications companies in Europe, Asia, and Africa.

"While we cannot disclose the identities or specific countries of affected entities, we observed the actor beginning relay-based operations in the
second half of 2025, followed by a gradual expansion in victim coverage from each relay over time," the researchers said.
