Your credentials hit Telegram before your SIEM sees anything
Stealer log monitoring gives your team visibility into the fastest-moving credential source in the threat landscape. LeakyCreds ingests logs from 50+ infostealer families daily — catching exposed credentials hours after device infection.
Stealer logs: what your EDR doesn't tell you
When Lumma Stealer or RedLine infects a device, it does one thing fast: extract every saved credential, session cookie, and autofill entry from every browser on the machine. Chrome, Firefox, Edge, Opera — all fair game. The payload gets packaged into a log and uploaded to a C2 server or Telegram channel, usually within hours.
From there, the economics take over. Malware operators running MaaS (Malware-as-a-Service) programs sell access to logs through private Telegram channels and underground markets. Logs containing corporate credentials — VPN endpoints, SSO portals, internal tools — command premium prices. Some operators post partial dumps publicly to attract buyers. Others maintain subscriber-only feeds with fresh logs dropping multiple times a day.
Here's why stealer logs are more dangerous than traditional breach dumps: they're fresh (hours old, not months), they contain session cookies that bypass MFA entirely, and they're pre-sorted by domain — making targeted account takeover trivial. A threat actor doesn't need to crack a password hash. They replay a session cookie and land inside your Okta or Google Workspace instance without triggering a single MFA prompt.
Infection to exploitation: the timeline
This is how fast credential theft plays out in practice. The entire chain — from initial infection to account takeover — can complete in under a week.
Employee device infected
Malicious download, poisoned ad, or compromised website. Infostealer executes and begins harvesting browser data immediately.
Log uploaded to Telegram or C2
Passwords, cookies, and autofill data packaged and exfiltrated. LeakyCreds detects your credentials here — the earliest possible point.
Logs sold or distributed to buyers
Threat actors purchase logs from Telegram channels or dark web markets. Corporate credentials get filtered and prioritized for exploitation.
Credential stuffing and session replay attacks begin
Stolen passwords tested against your VPN, email, and SaaS tools. Session cookies replayed to bypass MFA and access accounts directly.
Account takeover, lateral movement, data exfiltration
Without detection, attackers pivot through internal systems. Most organizations discover the breach months later — if they discover it at all.
LeakyCreds catches your credentials at step 2 — before they reach buyers, before stuffing attacks start, before session cookies are replayed. Continuous monitoring means your team gets alerted within hours of exposure, not weeks.
COVERAGE
50+ active infostealer families monitored
New families are added as they emerge. Each link below includes a detailed threat profile with TTPs, distribution methods, and detection guidance.
THE PIPELINE
How LeakyCreds processes stealer logs
A dedicated ingestion pipeline built specifically for stealer log data — not repurposed breach monitoring infrastructure.
Collect
Continuous ingestion from Telegram channels, dark web markets, paste sites, and direct log feeds where stealer output first surfaces
Parse & Normalize
Logs from different stealer families have different formats. Our parsers normalize across 50+ families into a unified schema
Match & Score
Records matched against your domains in real time. Severity scored by source freshness, credential type, and whether session cookies are present
Alert & Attribute
Webhook fires with full context: stealer family, Telegram channel, detection timestamp, credential type, and severity
Stealer log monitoring ≠ dark web monitoring
Dark web monitoring: forums and marketplaces
Scrapes forums and marketplaces periodically. Credentials typically appear days or weeks after initial theft. Good for broad visibility, but too slow for stealer log threats.
Stealer log monitoring: raw malware output
Monitors the actual Telegram channels and feeds where infostealer operators distribute fresh logs. Credentials detected hours after infection, with session cookies and full source attribution.
LeakyCreds covers both — plus Telegram channel monitoring
We don't make you choose. LeakyCreds runs a dedicated stealer log pipeline alongside dark web and breach compilation monitoring. Telegram channels — where the majority of fresh Lumma, RedLine, and Vidar logs first appear — are covered by default.
