This rule detects the OXLOADER malware's technique of hijacking the CRT initializer table. It identifies an unsigned process loading a randomly named .ocx file (a copy of dui70.dll with an injected .xtext section) from a temporary or download path. The detection is further refined by correlating this with multiple VirtualAlloc calls, consistent with the malware's three rolling-XOR decryption stubs activated via the RegisterClipboardFormatW CRT initializer hook.
Detects ListPlanting injection using LVM_SORTITEMS and SendMessage API
Detects EWM injection using SetWindowLongPtr API for code execution
Detects ListPlanting injection using LVM_SORTITEMS and SendMessage API
This rule detects a 'ListPlanting Injection' attack via the SendMessage API payload within HTTP traffic. It specifically looks for the strings 'LVM_SORTITEMS' and 'SendMessage' (case-insensitive) in the file data of an HTTP response flowing to the client. This type of injection is often associated with shellcode or code injection techniques.
This query was originally published in the threat analytics report, Ransomware continues to hit healthcare, critical services. There is also a related blog.
In April of 2020, security researchers observed multiple ransomware campaigns using the same set of techniques.
The following query detects suspicious use of Alternate Data Streams (ADS), which may indicate an attempt to mask malicious activity. These campaigns have been known to deploy ransomware in-memory and exploit ADS.
The See also section below lists more queries related to techniques shared by these campaigns.
