Stealer Logs
Also known as: Stealer log, Infostealer logs, Logs
A stealer log is the package of data exfiltrated from a single device by infostealer malware. It typically contains saved passwords, session cookies, autofill data, system information, and sometimes files, and is sold or traded in bulk across cybercrime marketplaces and Telegram channels.
What is a stealer log?
When infostealer malware finishes harvesting data from a victim machine, it bundles that data into a structured archive known as a stealer log. Each log represents one infected device and usually includes a file of saved credentials, exported cookies, autofill and card data, a list of installed software and security tools, and a system fingerprint.
How stealer logs are traded
Stealer logs are sold individually, in curated bundles, or via subscription "log clouds" that grant buyers continuous access to fresh logs. They circulate on dark-web markets, dedicated forums, and private Telegram channels. Because the same log can be resold many times, a single exposure can reach a large number of criminal buyers.
Why stealer logs matter to defenders
Stealer logs are a direct, high-fidelity signal that a device — and the accounts used on it — has been compromised. Monitoring for your domains and identities in stealer logs lets you reset credentials, revoke sessions, and contain exposure before the data is weaponised.
VantaPrism collects and parses stealer logs from monitored channels, normalising them into searchable records. Teams can query domains, emails, and usernames to see exactly which logs contain their data, when the device was infected, and what was exposed.
