Security News > 2022 > April > Hackers target Ukrainian govt with IcedID malware, Zimbra exploits
Hackers are targeting Ukrainian government agencies with new attacks exploiting Zimbra exploits and phishing attacks pushing the IcedID malware.
The Computer Emergency Response Team of Ukraine detected the new campaigns and attributed the IcedID phishing attack to the UAC-0041 threat cluster, previously connected with AgentTesla distribution, and the second to UAC-0097, a currently unknown actor.
The attached images contain a content-location header that links to a web resource hosting JavaScript code that triggers the exploitation of the Zimbra CVE-2018-6882 vulnerability.
This cross-site scripting vulnerability affects Zimbra Collaboration Suite versions 8.7 and older, enabling remote attackers to inject arbitrary web script or HTML via a content-location header in email attachments.
Zimbra is an email and collaboration platform that also includes instant messaging, contacts, video conferencing, file sharing, and cloud storage capabilities.
CERT-UA advises all organizations in Ukraine using Zimbra to update to the latest available versions of the suite immediately.
