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.
