According to Gen, this is a potential internal test build that marks the transition of Lumma Stealer to a 64 bit version.

According to Gen, this is most likely the 64bit evolution of Lumma Stealer. It is capable of stealing stored browser passwords, cookies, cryptocurrency, and much more. It also uses EtherHiding to resolve C2s, replacing the traditional use of Steam and Telegram dead drop resolvers, and has additional anti-analysis checks.

According to Seqrite, this collector is delivered via a phishing mail and triggers via XSS in an active Zimbra session.

According to Google, GHOSTBLADE is delivered via the DarkSword exploit chain. GHOSTBLADE is a dataminer written in JavaScript that collects and exfiltrates a wide variety of data from a compromised device. Data collected by GHOSTBLADE is exfiltrated to an attacker-controlled server over HTTP(S). Unlike GHOSTKNIFE and GHOSTSABER, GHOSTBLADE is less capable and does not support any additional modules or backdoor-like functionality; it also does not operate continuously. However, similar to GHOSTKNIFE, GHOSTBLADE also contains code to delete crash reports, but targets a different directory where they may be stored.

According to Zscaler, SnappyClient was first observed in December 2025. It is a C++-based C2 implant with the ability to steal data and provide remote access. SnappyClient employs multiple evasion techniques to hinder endpoint security detection, including an Antimalware Scan Interface (AMSI) bypass, as well as implementing Heaven’s Gate, direct system calls, and transacted hollowing. SnappyClient receives two configuration files from the C2 server, which contain a list of actions to perform when a specified condition is met, along with another that specifies applications to target for data theft. SnappyClient uses a custom network communication protocol that encrypts all network communication using ChaCha20-Poly1305.

According to Nexttron Systems, RegPhantom is a stealthy Windows kernel rootkit designed to give attackers code execution in kernel mode while leaving very little visible evidence behind. The malware abuses the Windows registry as a covert trigger mechanism: a usermode process can send an encrypted command through a registry write, which the driver intercepts and turns into arbitrary kernel-mode code execution.

Cisco Talos attributes this backdoor with moderate confidence to the Bitter APT.

According to FireEye, ZXSHELL is a backdoor that can be downloaded from the internet, particularly Chinese hacker websites. The backdoor can launch port scans, run a keylogger, capture screenshots, set up an HTTP or SOCKS proxy, launch a reverse command shell, cause SYN floods, and transfer/delete/run files. The publicly available version of the tool provides a graphical user interface that malicious actors can use to interact with victim backdoors. Simplified Chinese is the language used for the bundled ZXSHELL documentation.

According to ESET, this malware family was active exclusively in Brazil until the middle of 2020. It s identified by its method for obfuscating strings. It creates a function for each character of the alphabet and then concatenates the result of calling the correct functions in sequence.

This family describes the (initially small) loader, which downloads Zeus OpenSSL. In June 2016, a new loader was dubbed DEloader by Fortinet. It has some functions borrowed from Zeus 2.0.8.9 (e.g. the versioning, nrv2b, binstorage-labels), but more importantly, it downloaded a Zeus-like banking trojan (-> Zeus OpenSSL). Furthermore, the loader shared its versioning with the Zeus OpenSSL it downloaded. The initial samples from May 2016 were small (17920 bytes). At some point, visualEncrypt/Decrypt was added, e.g. in v1.11.0.0 (September 2016) with size 27648 bytes. In January 2017 with v1.15.0.0, obfuscation was added, which blew the size up to roughly 80k, and the loader became known as Zloader aka Terdot. These changes may be related to the Moskalvzapoe Distribution Network, which started the distribution of it at the same time. Please note that IBM X-Force decided to call win.zloader/win.zeus_openssl "Zeus Sphinx", after mentioning it as "a new version of Zeus Sphinx" in their initial post in August 2016. Malpedia thus lists the alias "Zeus XSphinx" for win.zeus_openssl - the X to refer to IBM X-Force.

This family describes the vanilla Zeus-variant that includes TOR (and Polipo proxy). It has an almost 90% overlap with Zeus v2.0.8.9. Please note that IBM X-Force decided to call win.zloader/win.zeus_openssl "Zeus Sphinx", after mentioning it as "a new version of Zeus Sphinx" in their initial post in August 2016. Malpedia thus lists the alias "Zeus XSphinx" for win.zeus_openssl - the X to refer to IBM X-Force. Zeus Sphinx on the one hand has the following versioning ("slow increase") - 2015/09 v1.0.1.0 (Zeus Sphinx size: 1.5 MB) - 2016/02 v1.0.1.2 (Zeus Sphinx size: 1.5 MB) - 2016/04 v1.0.2.0 (Zeus Sphinx size: 1.5 MB) Zeus OpenSSL on the other hand has the following versioning ("fast increase") - 2016/05 v1.5.4.0 (Zeus OpenSSL size: 1.2 MB) - 2017/01 v1.14.8.0 (Zeus OpenSSL size: 1.8 MB) - 2017/01 v1.15.0.0 (Zeus OpenSSL size: 2.2 MB)

This family describes the Zeus-variant that includes a version of OpenSSL and usually is downloaded by Zloader. In June 2016, the version 1.5.4.0 (PE timestamp: 2016.05.11) appeared, downloaded by Zloader (known as DEloader at that time). OpenSSL 1.0.1p is statically linked to it, thus its size is roughly 1.2 MB. In subsequent months, that size increased up to 1.6 MB. In January 2017, with version 1.14.8.0, OpenSSL 1.0.2j was linked to it, increasing the size to 1.8 MB. Soon after also in January 2017, with version v1.15.0.0 the code was obfuscated, blowing up the size of the binary to 2.2 MB. Please note that IBM X-Force decided to call win.zloader/win.zeus_openssl "Zeus Sphinx", after mentioning it as "a new version of Zeus Sphinx" in their initial post in August 2016.

According to CrowdStrike, The two primary goals of the Zeus trojan horse virus are stealing people's financial information and adding machines to a botnet. Unlike many types of malware, most Zeus variants try to avoid doing long-term damage to the devices they infect. Their aim is to avoid detection from antivirus software.

ZeroEvil is a malware that seems to be distributed by an ARSguarded VBS loader. It first connects to a gate.php (version=). Upon success, an embedded VBS gets started connecting to logs_gate.php (plugin=, report=). So far, only one embedded VBS was observed: it creates and starts a PowerShell script to retrieve all password from the Windows.Security.Credentials.PasswordVault. Apart from that, a screenshot is taken and a list of running processes generated. The ZeroEvil executable contains multiple DLLs, sqlite3.dll, ze_core.DLL (Mutex) and ze_autorun.DLL (Run-Key).

ZeroCleare is a destructive malware. It has been developed in order to wipe the master boot record section in order to damage a disk's partitioning. Attackers use the EldoS RawDisk driver to perform the malicious action, which is not a signed driver and would therefore not runnable by default. The attackers managed to install it by using a vulnerable version of VBoxDrv driver, which the DSE accepts and runs. Used to attack middle-east energy and industrial sectors.

ZeroAccess is a modular botnet that was primarily active around 2012. It has been observed selling fake antivirus software to infected users, performing click fraud and deploying bitcoin miners. It utilizes both peer-to-peer networking and a centralized C&C, spoofing the HTTP Host header with fake DGA-generated domains to confuse researchers. While there is no evidence that the DGA-generated domains were ever intentonally contacted by the malware, faulty middleboxes still caused some requests to be sent to the DGA domains.
