JessieConTea is a remote access trojan that uses HTTP(S) for communication. It supports around 30 commands that include operations on the victim’s filesystem, basic process management, file exfiltration (both plain and zipped), and the download and execution of additional tools from the attacker’s arsenal. The commands are indexed by 32-bit integers, starting with the value 0x60D49D97. The malware was delivered in-the-wild via trojanized applications like DeFi Wallet or Citrix Workspace. JessieConTea generates POST parameters with a specific parameter name, jsessid, from which the initial part of its name is derived. Also, it contains a specific RTTI symbol ".?AVCHttpConn@@", which inspired the second part of the name. It uses RC4 for C&C traffic encryption.

2006 Gozi v1.0, Gozi CRM, CRM, Papras 2010 Gozi v2.0, Gozi ISFB, ISFB, Pandemyia(*) In September 2010, the source code of a particular Gozi CRM dll version was leaked. This led to two main branches: one became known as Gozi Prinimalka, which was merge with Pony and became Vawtrak/Neverquest. The other branch became known as Gozi ISFB, or ISFB in short. Webinject functionality was added to this version. There is one panel which often was used in combination with ISFB: IAP. The panel's login page comes with the title 'Login - IAP'. The body contains 'AUTHORIZATION', 'Name:', 'Password:' and a single button 'Sign in' in a minimal design. Often, the panel is directly accessible by entering the C2 IP address in a browser. But there are ISFB versions which are not directly using IAP. The bot accesses a gate, which is called the 'Dreambot' gate. See win.dreambot for further information. ISFB often was protected by Rovnix. This led to a further complication in the naming scheme - many companies started to call ISFB Rovnix. Because the signatures started to look for Rovnix, other trojans protected by Rovnix (in particular ReactorBot and Rerdom) sometimes got wrongly labelled. In April 2016 a combination of Gozi ISFB and Nymaim was detected. This breed became known as GozNym. The merge uses a shellcode-like version of Gozi ISFB, that needs Nymaim to run. The C2 communication is performed by Nymaim. See win.gozi for additional historical information.

According to Mitre, IronNetInjector is a Turla toolchain that utilizes scripts from the open-source IronPython implementation of Python with a .NET injector to drop one or more payloads including ComRAT.

IRONHALO is a downloader that uses the HTTP protocol to retrieve a Base64 encoded payload from a hard-coded command-and-control (CnC) server and uniform resource locator (URL) path. The encoded payload is written to a temporary file, decoded and executed in a hidden window. The encoded and decoded payloads are written to files named igfxHK[%rand%].dat and igfxHK[%rand%].exe respectively, where [%rand%] is a 4-byte hexadecimal number based on the current timestamp. It persists by copying itself to the current user’s Startup folder.
