Vasport is a Windows backdoor associated with persistence through Registry Run key autostart entries after copying itself to disk. It supports command-and-control communications over HTTP by creating a backdoor channel using HTTP POST requests, and it is capable of tunneling communications through a proxy. These traits indicate an implant designed for durable remote access and network-aware operation in environments where outbound traffic may be mediated by proxy infrastructure.
Mallory pivots from this family to the IOCs, detections, and named campaigns that touch your stack, and pages you when something new lands.
7 distinct techniques documented for this family, organized by ATT&CK tactic.
Across the content, malware repeatedly 'adds Registry Run keys', 'creates Registry entries', 'modifies the Windows Registry', or 'overwrites registry keys' to maintain persistence.
ADVSTORESHELL achieves persistence by adding itself to the HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Run Registry key... APT28 has deployed malware that has copied itself to the startup directory for persistence... FIN7 malware has created Registry Run and RunOnce keys to establish persistence, and has also added items to the Startup folder.

The content is a long ATT&CK-style listing showing numerous malware families and threat groups that 'use HTTP,' 'use HTTPS,' 'HTTP POST requests,' 'HTTP GET requests,' or 'HTTP/S' for command and control communications.
"APT41 used a tool called CLASSFON to covertly proxy network communications." / "BADCALL functions as a proxy server between the victim and C2 server." / "Sandworm Team's BCS-server tool can create an internal proxy server to redirect traffic..."
