+# Detect network connection events on a device impacted by the Dudear campaign
+
+This query was originally published in the threat analytics report, *The expansion of Dudear (TA505)*.
+
+The [Dudear](https://www.msn.com/en/news/technology/microsoft-detects-new-evil-corp-malware-attacks/ar-BBZxkRs) campaign spreads commodity malware for profit. Other security researchers have given the name *TA505* to a group performing similar or related malicious activity.
+
+The Dudear campaign targets financial services or healthcare. They involve several kinds of malware implants, including a family of trojan droppers also known as [Dudear](https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=TrojanDropper:O97M/Dudear.A!dha&threatId=-2147217587). Dudear campaign operators often use Remote Access Trojans (RATs) for command-and-control, lateral movement, and credential dumping.
+
+The following query finds network connection events on a device that has connected to a Dudear IP address. To find these devices, see [Detect devices connected to Dudear campaign IPs](dudear.ip.md).
+
+## Query
+
+```Kusto
+// All network connection spawned by malicious actions on impacted machine
+DeviceNetworkEvents 
+| where InitiatingProcessFileName in ("rundll32.exe", "winless.exe", "reduce1.exe", "64.exe", "excel.exe", "wsus.exe")
+| where Timestamp >= datetime(2019-12-06)
+```
+
+## Category
+
+This query can be used to detect the following attack techniques and tactics ([see MITRE ATT&CK framework](https://attack.mitre.org/)) or security configuration states.
+
+| Technique, tactic, or state | Covered? (v=yes) | Notes |
