Top Highlights Business Email Compromise (BEC) is a sophisticated scam where cybercriminals impersonate trusted individuals or vendors to steal money or sensitive information, costing billions annually. Recent trends include AI-based impersonations, fake invoices, QR code attacks, and hijacked email threads, making BEC increasingly sophisticated and hard to detect. Notable BEC attacks have targeted top companies like Facebook, Google, and Toyota, resulting in losses from hundreds of thousands to over $121 million. Defense strategies emphasize verifying requests through known contacts, implementing approval tiers, training staff, and adopting email security tools to prevent such scams. Underlying Problem Business email compromise (BEC) is…

Fast Facts An ex-L3 Harris cybersecurity executive, Williams, was sentenced to over seven years (87 months) in prison for stealing and selling eight zero-day exploits to a Russian broker, earning $1.3 million. Williams used his access at Trenchant, a unit owned by L3Harris, to acquire proprietary US government and allied partner exploits over three years, violating confidentiality laws. The exploits were sold to “Company 3,” identified as Operation Zero, a Russian exploit broker sanctioned by the U.S. Treasury, which markets itself for purchasing zero-day vulnerabilities. The theft caused approximately $35 million in losses to L3Harris, while Williams admitted to profiting…

Top Highlights In 2025, cyber attackers weaponized AI tools for rapid, precise intrusions, reducing average lateral movement time to 29 minutes and record cases to just 27 seconds. AI abuse enabled attackers to insert malicious prompts and scripts into legitimate environments, greatly accelerating attack speeds and evasion, with most malware-free detection. Threat groups utilized AI-generated scripts and tools across all attack phases, doubling their activity and sophistication compared to the previous year. Organizations must actively monitor AI tool usage, patch platforms swiftly, audit dependencies, and ensure cross-domain visibility to detect and stop these fast-moving intrusions. The Core Issue In 2025,…

Summary Points The financial sector faces escalating cyber threats, with 65% of organizations attacked by ransomware in 2024, leading to high recovery costs averaging $2.73 million. 90% of attacks originate from phishing, and despite rising security investments, nearly one-third of threats bypass traditional defenses, emphasizing the need for rapid threat insights. Current security tools like SIEM and EDR struggle with alert fatigue and delayed threat detection, increasing response times and operational risks. ANY.RUN’s Threat Intelligence platform enhances early detection, reduces MTTR, and shifts SOCs from reactive to proactive threat hunting, safeguarding business resilience and compliance. What’s the Problem? Recent reports…

Fast Facts A Russian-linked group, Diesel Vortex, operated a large-scale phishing campaign targeting freight and logistics companies across the US and Europe from September 2025 to February 2026, stealing over 1,649 login credentials. They used sophisticated methods like dual-domain phishing pages, embedding hidden malicious content to evade detection, and intercepted MFA codes in real-time via spearphishing and voice calls. The operation sold access as a Phishing-as-a-Service (PhaaS) under the brand “MC Profit Always,” with plans for cryptocurrency-based transactions, and compromised data enabled shipment redirection, fraud, and cargo reselling. Investigations uncovered exposed source code, victim databases, and operational details on compromised…
