An OAuth supply chain compromise at Vercel exposed how trusted third party apps and platform environment variables can bypass traditional defenses and amplify blast radius. This article examines the attack chain, underlying design tradeoffs, and what it reveals about modern PaaS and software supply chain risk.

Not every cloud breach starts with malware or a zero-day. In this incident, attackers discovered an exposed Spring Boot Actuator endpoint, harvested credentials from leaked configuration data, then used the OAuth2 Resource Owner Password Credentials (ROPC) flow to authenticate without MFA.

Tycoon 2FA was dismantled this week by law enforcement and industry partners including TrendAI™. The phishing-as-a-service platform offered MFA bypass services using adversary-in-the-middle (AitM) proxying.

We uncover how a campaign used Atlassian Jira Cloud to launch automated and targeted spam campaigns, exploiting trusted SaaS workflows to bypass security controls.

Cybercriminals are abusing AI-native platforms like Vercel, Netlify, and Lovable to host fake captcha pages that deceive users, bypass detection, and drive phishing campaigns.

Combining AI-generated code and social engineering, EvilAI operators are executing a rapidly expanding campaign, disguising their malware as legitimate applications to bypass security, steal credentials, and persistently compromise organizations worldwide.

Crypto24 is a ransomware group that stealthily blends legitimate tools with custom malware, using advanced evasion techniques to bypass security and EDR technologies.

Our Threat Hunting team discusses Earth Preta’s latest technique, in which the APT group leverages MAVInject and Setup Factory to deploy payloads, bypass ESET antivirus, and maintain control over compromised systems.

In addition to our Water Hydra APT zero day analysis, the Zero Day Initiative (ZDI) observed a DarkGate campaign which we discovered in mid-January 2024 where DarkGate operators exploited CVE-2024-21412.

This blog delves into the Phemedrone Stealer campaign's exploitation of CVE-2023-36025, the Windows Defender SmartScreen Bypass vulnerability, for its defense evasion and investigates the malware's payload.

After months of investigation, we found that several undisclosed malware and interesting tools used for exfiltration purposes were being used by Earth Preta. We also observed that the threat actors were actively changing their tools, tactics, and procedures (TTPs) to bypass security solutions. In this blog entry, we will introduce and analyze the other tools and malware used by the threat actor.

We look into some of the implementations that cybercriminals use to bypass the Windows Antimalware Scan Interface (AMSI) and how security teams can detect threats attempting to abuse it for compromise with Trend Micro Vision One™.

This blog entry discusses the technical details of how we exploited CVE-2022-22583 using a different method. We also tackle the technical details of CVE-2022-32800, another SIP-bypass that we discovered more recently, in this report.

More than two years ago, a researcher, A2nkF demonstrated the exploit chain from root privilege escalation to SIP-Bypass up to arbitrary kernel extension loading. In this blog entry, we will discuss how we discovered 3 more vulnerabilities from the old exploit chain.

Malicious actors take advantage of people’s reliance on web servers to perform attacks like remote code execution, access control bypass, denial of service, or even cyberjacking the victim servers to mine cryptocurrencies.
