New Threat(s) Detected

The following detections were added to your Stamus NDR this past week:

 

SpyPress (Data Theft)

 

SpyPress is a collection of obfuscated Javascript payloads targeting various webmail frameworks. The payloads have common characteristics, including encryption of URLs and variable names. They are fully contained within email messages.

• Kill chain phase(s): command and control, delivery

• MITRE ATT&CK: T1041, T1071, T1505

 

ZimReaper (Data Theft)

 

Seqrite Labs discovered a targeted phishing attack exploiting a XSS vulnerability in Zimbra Collaboration to compromise a Ukrainian government entity. The attack chain lives inside a single email.

 

• Total number of detection methods: 6

• Kill chain phase(s): command and control, actions on objectives

• MITRE ATT&CK: T1041, T1114, T1048
