Process Parameter Poisoning: The EDR Evasion Technique That's Rewriting Endpoint Security Rules

In September 2026, cybersecurity researchers at Flashpoint validated a sophisticated EDR evasion technique called 'process parameter poisoning,' originally discovered by Max Hirschberger and Ogulcan Ugur in July 2026. This technique allows attackers to inject malicious code into Windows process initialization structures without using traditional Windows APIs that EDR tools monitor, such as VirtualAllocEx() and WriteProcessMemory(). When combined with additional evasion methods like DLL unhooking and non-Microsoft DLL blocking policies, the technique successfully bypassed multiple market-leading EDR solutions without generating any security alerts. This discovery represents a significant shift in the cybersecurity landscape as threat actors increasingly develop advanced techniques to circumvent endpoint detection systems. The research highlights the growing sophistication of EDR evasion methods and the need for security teams to monitor actual process behavior rather than relying solely on traditional API monitoring approaches.

How Attackers Exploit URL Parser Differences in Advanced Phishing Campaigns
How Attackers Exploit URL Parser Differences in Advanced Phishing Campaigns

How Attackers Exploit URL Parser Differences in Advanced Phishing Campaigns

Security researchers at SANS Internet Storm Center documented a sophisticated phishing campaign exploiting URL parser differences to evade detection systems. The attack utilized three distinct techniques: RFC 3986 userinfo fields with tracking tokens, malformed hostnames with hyphens that bypass strict validators, and victim email addresses in URL paths that confuse parsing logic. These methods created URLs that appeared as legitimate email addresses or trusted domains to security filters while directing browsers to attacker-controlled phishing sites. The campaign demonstrated how attackers exploit discrepancies between different URL parsing implementations rather than traditional vulnerabilities. This incident highlights the growing sophistication of phishing campaigns that exploit fundamental protocol ambiguities and parser inconsistencies. As organizations implement zero-trust architectures and advanced email security, attackers are adapting with techniques that manipulate how different systems interpret the same URL string.

Ryuk Ransomware Architect Sentenced: Lessons for Modern Enterprise Security

Karen Serobovich Vardanyan, a 35-year-old Armenian national known online as 'Maneeken' or 'Karl Lagerfeld,' was sentenced to 24 months in prison for his role in Ryuk ransomware attacks between March 2019 and June 2020. Vardanyan specialized in gaining initial access to corporate networks, helping his cybercriminal group breach multiple U.S. organizations including companies in Michigan, Texas, and Oregon. The group collected over $15 million in ransom payments, with one Michigan company alone paying 200 BTC worth over $1.1 million. Vardanyan was extradited from Ukraine in 2025 and pleaded guilty in July 2026. This sentencing highlights the ongoing global law enforcement efforts to prosecute ransomware operators, even years after attacks occurred. As ransomware groups continue to evolve and fragment into smaller units, the Ryuk-to-Conti evolution demonstrates how cybercriminal organizations adapt and rebrand while maintaining similar attack methodologies.
