SnakeBiteAgent RAT: Remove Remote Access and Secure Accounts

SnakeBiteAgent RAT is a Windows remote-access trojan that can expose credentials and give an attacker control of an infected PC. If you ran a suspicious file and a security alert identifies this threat, disconnect the PC from the network and use another, clean device for important accounts. Removing the downloaded ZIP is only the beginning: check for unauthorized remote-support software, complete malware cleanup, and review account access separately.

If the archive was saved but nothing inside it ran, start by preserving the alert and keeping the file blocked. The response should follow what happened on your computer, rather than assuming that every download became a full compromise.

What is confirmed about SnakeBiteAgent?

In its September 1, 2026 report, ANY.RUN described a .NET implant found in a business-themed ZIP archive. The reported capabilities include credential theft, keylogging, hidden-desktop access, webcam and microphone capture, and installation of AnyDesk or MeshCentral to provide additional remote access. [1]

Those are capabilities documented by the researcher, not a list of things proven to have happened on every affected PC. This guide explains how to respond to that exposure; it does not claim that we tested a family-specific removal procedure. A generic antivirus label, an unfamiliar process, or a remote-support app alone cannot identify SnakeBiteAgent.

The broader remote access trojan guide explains the difference between malicious control and legitimate remote administration. For this threat, the practical concern is that the original malware and an additional remote-access agent may need separate attention.

Did you save the ZIP, extract it, or run a file?

Use the closest situation below. If you cannot tell whether something executed, keep the PC offline while you check the security history or ask your IT team.

• You only saved the archive. Do not open it to investigate. Keep the detection quarantined, record the download source and alert, and run a current scan. A blocked download is different from evidence of an active remote session.
• You extracted files but did not deliberately run them. Record the extracted folder and check whether the security alert describes a file inside the archive or a running process. Extraction alone does not establish execution in the reported case. Do not launch an executable or shortcut to find out what it does.
• You ran a file, approved a prompt, or installed something from the archive. Disconnect Wi-Fi and Ethernet, stop using that PC for email and payments, and follow both the device and account steps below. The program failing to show a document does not mean nothing ran.
• You see fresh remote activity or confirmed detections after cleanup. Keep the device isolated. Preserve the new timestamps and commands, then involve a trusted technician or business IT team. Repeatedly deleting the same visible file can leave the access mechanism unresolved.

For a work computer, notify IT using another device before uninstalling software or restarting. They may need the running state and endpoint logs to determine which systems and accounts were exposed.

Record the evidence before removing entries

1. Save the security product’s exact detection name, affected-file path, detection time, and action. Note whether it says blocked, quarantined, remediation pending, or something else.
2. Record the suspicious download’s name, source, approximate opening time, and extracted folder. For example, %USERPROFILE%\Downloads is a place to check against your own alert, not a SnakeBiteAgent indicator or a folder to delete wholesale.
3. Note unexpected remote-support apps, new startup entries, and the time you first noticed them. Keep screenshots or notes locally for your technician; do not post account details or business documents to public analysis services.
4. Leave quarantine intact. Do not restore the file, add an exclusion, or rerun the archive to produce a clearer screenshot.

Check unexpected AnyDesk or MeshCentral access

ANY.RUN’s report makes this check relevant: SnakeBiteAgent can install additional remote-access tools. AnyDesk and MeshCentral also have legitimate uses. The key question is who authorized this installation and where its service or startup command points.

1. Establish ownership. Check Installed apps and ask the person or IT team that normally supports the PC. Compare the app, installation path, and timing with their records. A familiar product name or a valid signature does not establish that this particular installation was authorized.
2. Inspect automatic launch points. Microsoft Sysinternals Autoruns shows logon entries, scheduled tasks, and services. Use those tabs to find the relevant executable and inspect its Properties and Jump to Entry information. The official documentation and download are in References. [2]
3. Save the exact entry and command. Compare its path with the alert and installation record. Do not disable unrelated Windows services, every unsigned item, or every remote-support tool.
4. Remove confirmed unauthorized access. On a personal PC, uninstall an identified unwanted remote-support installation through Installed apps. If a clearly identified unwanted startup entry remains, uncheck that individual entry in Autoruns to disable it. On a managed PC, let IT remove the agent and its associated access through the approved process.

Closing a remote-support window is not the same as removing its background service. Conversely, finding a service does not prove it was installed by this RAT. If ownership or the command is unclear, keep the device isolated and provide the saved details to someone who can verify them.

Scan the PC and check what returns

Quarantining an initial payload may leave another component or an installed remote-access agent behind. That possibility matters when the suspicious file already ran, a service reappears, or activity returns after a restart.

After containment and the checks above, run a full Gridinsoft Anti-Malware scan. Review the findings, remove confirmed detections, and complete any requested restart. Obtain the installer from the official site using a clean device if necessary; do not resume normal browsing or account use on the suspect PC while you prepare cleanup.

Then compare the results with your saved evidence:

• A new detection, restored entry, or remote-access service appears: save its current time and path and escalate the continuing activity. An old entry in scan history is not a new detection.
• An error remains but its target file is gone: identify the surviving launch command before assuming the malware returned. Do not restore the missing target to silence the error.
• Scans complete and the unwanted access stays removed: continue monitoring and finish account recovery. A clean scan helps assess the current device; it cannot show that credentials or files were never accessed.

Secure accounts from a clean device

If the payload ran, treat account recovery as a separate workstream. Start with the main email account that can reset other passwords, then important work, financial, and social accounts used or stored on the affected PC.

1. Change important passwords to unique ones and use each provider’s option to revoke sessions or sign out other devices.
2. Review recovery addresses, phone numbers, multifactor settings, connected apps, and recent sign-in activity. For email, also check forwarding and mailbox rules you did not create.
3. Enable phishing-resistant authentication where available. If unauthorized payments or account changes occurred, contact the provider through its official app or website.
4. Keep the affected PC out of those accounts until its cleanup or rebuild is complete. If you already changed passwords on it while remote access may have been active, change them again from a clean device.

For a personal Microsoft account, Sign out everywhere is in Advanced security options. Microsoft says the sign-out can take up to 24 hours and excludes Xbox consoles; do not mistake clicking the button for immediate revocation on every device. [3] Work and school accounts should be handled with the organization’s administrator.

The post-download account recovery checklist expands this sequence. Password changes and session revocation protect accounts; a malware scan does not perform those actions for you.

When a clean Windows installation is the better option

Consider a clean rebuild when confirmed remote control occurred and you cannot establish the scope, unwanted services or detections return, or security settings remain altered. Business IT should make that decision for managed equipment after preserving the evidence it needs.

Use the clean Windows installation USB guide to prepare media on a trusted device and preserve necessary personal documents. Avoid carrying the suspect archive, unknown installers, or a complete browser profile into the fresh system. Account recovery still matters after reinstalling.

For future business downloads, confirm unexpected requests through a known contact channel before opening attachments. Check the actual file type and stop if a supposed document asks you to run software or approve an unexpected system prompt. Keep Windows and the archive application updated.
