VodkaStealer

VodkaStealer is a custom C++ information stealer observed as a payload in a large ClickFix campaign that used compromised legitimate WordPress sites to target primarily Windows users. In the reported activity, attackers injected malicious JavaScript into WordPress sites and displayed fake Cloudflare human-verification/CAPTCHA prompts that instructed victims to paste commands into the Windows Run dialog, leading to a multi-stage, largely in-memory infection chain. Rapid7 reported the broader operation had been active in this form since December 2025, with some supporting infrastructure dating to July/August 2025, and identified more than 250 compromised websites across at least 12 countries. VodkaStealer was delivered alongside other payloads including Vidar Stealer, Impure Stealer, and the DoubleDonut loader. The malware family is described as capable of harvesting browser credentials, authentication cookies, cryptocurrency wallet data, and other sensitive information from infected devices. Rapid7 specifically described VodkaStealer as the latest payload observed at the end of the DoubleDonut chain. High-confidence associations in the provided content tie VodkaStealer to financially motivated malware distribution via ClickFix/social-engineering lures on compromised WordPress infrastructure; no specific threat actor attribution beyond that is provided.

MITRE ATT&CK

Techniques & procedures

13 distinct techniques documented for this family, organized by ATT&CK tactic.

Initial Access

1 technique
T1189Drive-by CompromiseEvidence4

Highly trusted WordPress websites are being compromised as part of an ongoing, widespread campaign designed to inject a ClickFix implant impersonating a Cloudflare human verification challenge.

Execution

2 techniques
T1059Command and Scripting InterpreterEvidence1

Visitors are instructed to complete the verification by copying and pasting a command into the Windows Run dialog box.

T1204User ExecutionEvidence3

Unlike traditional exploit-based attacks, this method relies entirely on user interaction – usually in the form of copying and executing commands.

Privilege Escalation

1 technique
T1055Process InjectionEvidence1

"...execute it utilizing the VirtualAlloc and CreateThread Windows APIs..." and "...injected into a native svchost.exe process..."; "OpenProcess... VirtualAllocEx, WriteProcessMemory and CreateRemoteThread"

Stealth

1 technique
T1055Process InjectionEvidence1

"...execute it utilizing the VirtualAlloc and CreateThread Windows APIs..." and "...injected into a native svchost.exe process..."; "OpenProcess... VirtualAllocEx, WriteProcessMemory and CreateRemoteThread"

Credential Access

4 techniques
T1539Steal Web Session CookieEvidence2

The payloads delivered include Vidar Stealer, Impure Stealer, VodkaStealer and the DoubleDonut loader - all capable of harvesting browser credentials, authentication cookies, cryptocurrency wallet data and other sensitive information from infected devices.

T1555Credentials from Password StoresEvidence1

The payloads delivered include Vidar Stealer, Impure Stealer, VodkaStealer and the DoubleDonut loader - all capable of harvesting browser credentials, authentication cookies, cryptocurrency wallet data and other sensitive information from infected devices.

T1555.003Credentials from Web BrowsersEvidence1

"...ultimately steals and exfiltrates credentials and digital wallets..."; "...targeting Google Chrome, Microsoft Edge, Brave..."

T1649Steal or Forge Authentication CertificatesEvidence1

The stealer is equipped to harvest a wide range of data from compromised hosts, including exfiltrating credentials, files, keychain databases, and seed phrases from cryptocurrency wallets.

Collection

1 technique
T1005Data from Local SystemEvidence1

The stealer is equipped to harvest a wide range of data from compromised hosts, including exfiltrating credentials, files, keychain databases, and seed phrases from cryptocurrency wallets.

Command and Control

3 techniques
T1071.001Web ProtocolsEvidence1

"Invoke-WebRequest" to retrieve payloads; "...fetch a script..."; "...download a shellcode blob..."

T1104Multi-Stage ChannelsEvidence1

"...multi-stage malware chain..."; "...Donut loader is used twice in sequence..."

T1573.001Symmetric CryptographyEvidence1

"...AES-256-CBC with a server-provided key for encryption of C2 communication..."

Exfiltration

1 technique
T1041Exfiltration Over C2 ChannelEvidence1

"...steals and exfiltrates credentials and digital wallets..." and ATT&CK table listing "T1041 Exfiltration Over C2 Channel"
