Agent Tesla infections.

We monitor Agent Tesla logs in real-time. Enter your domain on our scanner to identify exposed credentials associated with this malware family and act before attackers use them.

Infection Vector
Malicious attachments and macro-enabled documents
Primary Target
Keystrokes, email credentials, and clipboard data
Primary Objective
Credential interception and long-lived surveillance
Monitoring Signal
Credential exposure paired with keylogging-oriented collection

About this Malware

Agent Tesla is a spyware and credential stealer that combines keylogging, clipboard capture, form grabbing, and email client theft. It is heavily distributed through malicious attachments and macro-laced documents. Collected data is exfiltrated over SMTP, FTP, or HTTP, supporting sustained espionage, account theft, and business email compromise inside enterprise environments.

Unlike many purely browser-focused families, Agent Tesla often supports ongoing surveillance characteristics. Impact may include repeated credential leakage over time as users continue working on compromised devices. Security response should combine account hardening with endpoint containment and email-channel analysis, especially in teams handling finance, support, and external partner communication.

Agent Tesla
Use Case
Threat exposure triage and response prioritization

Common Indicators in Leaked Logs

  • Credential records linked to email clients and repetitive exfil cadence
  • Multiple leaks from the same user profile over extended periods
  • Compromised mail accounts correlated with phishing relay behavior
  • Exposure events following malicious attachment campaigns

Recommended Actions

  • Reset email and SSO credentials for all exposed users
  • Contain compromised endpoints and inspect persistence mechanisms
  • Review mailbox forwarding rules and suspicious outbound activity
  • Enable continuous alerting for repeat Agent Tesla detections

FAQ

What does Agent Tesla typically steal?

Agent Tesla campaigns commonly target credentials, browser session material, and identity artifacts that enable account takeover. Monitoring leaked records helps security teams detect exposed users early and reduce attacker dwell time.

How does LeakyCreds detect Agent Tesla exposure?

LeakyCreds continuously monitors stealer log intelligence and related leak sources, then maps exposed records back to your domain. Teams can validate impact quickly and prioritize remediation by user and risk profile.

What should we do after a positive Agent Tesla match?

Start with password resets, session revocation, and MFA enforcement for impacted identities. Then investigate endpoint compromise paths, block repeat infection vectors, and keep continuous monitoring active for delayed log publication.
