Stolen Credentials, Silent Threats: How Infostealer Malware Is Fueling a New Wave of Cyberattacks

In this urgent and eye-opening white paper, HackNotice explores the escalating threat landscape shaped by infostealer malware—a growing force behind the dramatic rise in account takeovers (ATO) and business email compromise (BEC) attacks. Drawing on proprietary dark web intelligence, this report uncovers how billions of stolen credentials, session cookies, and authentication tokens are being used to bypass multi-factor authentication and infiltrate corporate environments undetected. From real-world case studies to emerging attack techniques, this white paper offers critical insights for security teams determined to stay ahead of today’s stealthiest cyber threats.

Infostealers are exploding in volume

Over 6 billion credentials were stolen by infostealers in 2024 alone—fueling a massive underground market.

MFA isn’t a silver bullet

Attackers are using session cookies and authentication tokens to sidestep multi-factor authentication entirely.

Credential marketplaces are thriving

Telegram and dark web log markets have made stolen login data cheap, searchable, and widely accessible.

Real breaches show real risk

Case studies—including the Snowflake cloud breach—show how years-old credentials are still being used for fresh attacks.

BEC scams are more dangerous than ever

With corporate email credentials in hand, attackers can impersonate employees and divert money or data.

Defense requires more than firewalls

Learn how to detect leaked credentials, limit lateral movement, and prepare incident response plans before attackers strike.
