Streaming Defense Announces Immediate Detection for Salt Typhoon’s Custom SFTP Exfiltration Tool
Streaming analytics and agentic workflows deliver instant detection – enterprise wide.
FOR IMMEDIATE RELEASE
August 28, 2025 Chicago, IL — Streaming Defense today announced immediate availability of new detections for the Chinese state–sponsored activity cluster commonly tracked as “Salt Typhoon.” The release adds precise coverage for the group’s custom Linux SFTP clients and their exfiltration tradecraft, along with real‑time correlation against IP indicators of compromise (IOCs) and unusual data transfer behaviors.
​
Leveraging our proprietary streaming analytics and agentic workflows, customers can now automatically identify Salt Typhoon’s SFTP exfiltration patterns, flag policy‑violating file movements, and correlate suspected staging activity to advisory-listed IP infrastructure in real time. The core detectors were already built into the Streaming Defense platform and require no downtime or manual tuning.
​
“Rapidly operationalizing intelligence is why we built Streaming Defense,” said Tom Miller, Chief of Strategy at Streaming Defense. “As soon as indicators and tradecraft details are published, our platform converts them into production‑grade analytics that spot the adversary’s behaviors on the wire—before valuable data walks out the door.”
What’s covered:
-
Identification of Salt Typhoon’s custom SFTP clients.
-
Automated correlation against the advisory’s IP IOC set with continuous updates.
-
Anomalous data‑transfer detection for SFTP/FTP/TFTP flows to unapproved hosts.
-
Alerting for signs of on‑box service enablement and tunneling frequently observed with this activity.
