Complete history of cyber attacks, key threat analysis, and essential resources to check if your data has been compromised
Understanding the cyber threat landscape is crucial for protecting yourself and your organization
U.S. losses to online crime hit $16+ billion in 2024, up 33% year-over-year according to the FBI's IC3 report.
View FBI ReportThe global average cost of a data breach reaches into the multi-million-dollar range, with healthcare and financial sectors hit hardest.
IBM Cost ReportRansomware and mass-exploitation campaigns like MOVEit and Log4Shell show how one flaw can ripple through thousands of organizations.
MOVEit AnalysisCISA's Known Exploited Vulnerabilities (KEV) catalog is the definitive list of threats being actively used by attackers right now.
View KEV CatalogA cyber attack is any deliberate attempt to disrupt, disable, steal from, or gain unauthorized control of a computer system or network. This includes phishing, malware and ransomware, supply-chain compromises, DDoS, zero-day exploitation, data exfiltration, and attacks on industrial control systems (ICS).

TechCrunch AnalysisSocial engineering attacks target major casino operations. Caesars reportedly paid ~$15M ransom; MGM faced ~$100M impact.
Attack OverviewRansomware attack triggers nationwide healthcare disruption. ~$22M ransom reportedly paid with multibillion-dollar fallout.
WIRED ReportUnderstanding the most common and dangerous cyber attack methods in plain English
Sophisticated social engineering attacks that trick users into sending money, credentials, or sensitive information. BEC attacks alone cause billions in losses annually.
Malicious software that encrypts systems and/or threatens to leak stolen data unless ransom is paid. Modern variants often combine encryption with data theft.
Attacks that abuse trusted software updates or vendor relationships to gain widespread access. These attacks leverage existing trust relationships.
Attacks targeting previously unknown vulnerabilities or widely-used components before or just after public disclosure. These create massive exposure windows.
Distributed attacks that flood services with traffic to make them unavailable. Often used as cover for other attacks or for extortion purposes.
