October 22, 2026: We updated this post to add the AWS WAF PHP application managed rule group. Version 2.3 of the rule group adds the PHP2Shell_BODY rule for CVE-2026-109619, and AWS made it the default version. On October 21, 2026, the PHP project released emergency fixes for two critical remote code execution (RCE) vulnerabilities in the […]

Amazon Threat Intelligence identified a PHP2Shell exploitation attempt dating to Oct. 17, 2026, in MadPot telemetry, four days before public disclosure of CVE-2026-109618 and CVE-2026-109619. The exploit attempt originated from an IP address associated with a commercial anonymization network. While the vulnerability was under embargo, the targeting of a honeypot from an anonymized IP address […]

Using temporary credentials is a security best practice to reduce the risk from credentials getting compromised. With AWS IAM Roles Anywhere, now your workloads outside of Amazon Web Services (AWS) will be able to access AWS resources by obtaining temporary security credentials in AWS Identity and Access Management (IAM). IAM Roles Anywhere relies on public […]

October 20, 2026: This post was republished to reflect the new migration capability from Active Directory to an external identity provider (IdP) or the Identity Center directory, now available in IAM Identity Center. September 2, 2026: This post was republished to include Active Directory migration strategies and automation for permission sets. AWS IAM Identity Center […]

We applied AWS Security Agent (now part of AWS Continuum), our autonomous penetration-testing agent, to 37 real, recently disclosed Common Vulnerabilities and Exposures (CVEs), each packaged as a live, containerized target with a flag hidden at the vulnerability’s intended sink. Starting from an unauthenticated or low-privilege position (an endpoint URL and a one-line hint, no […]

Most security tooling that fits into a CI/CD pipeline—static analysis (SAST), software composition analysis (SCA), and dynamic scanners (DAST)—flags potential issues from patterns and signatures. A flagged pattern shows you where to look; penetration testing is what confirms whether something is actually exploitable. That confirmation has traditionally come from a periodic, out-of-band engagement that runs […]

If you’ve ever looked at a list of cybersecurity jobs and felt like none of them fit you, you might just be looking at a short list. Most career guides cover the same few roles, like the analyst watching alerts or the pen tester (penetration tester, someone hired to legally break into systems to find […]

Amazon GuardDuty Extended Threat Detection correlates weak GuardDuty signals into a single, critical-severity attack sequence finding when their composition crosses a threshold of credibility. On May 20, 2026, the service started attaching five new indicator types to those sequences: MALICIOUS_PACKAGE, MISCONFIGURATION, REACHABILITY, SENSITIVE_DATA, and VULNERABILITY. For more information, see Document history for Amazon GuardDuty and […]

You want to set a cryptographic algorithm policy and stop non-compliant choices from being made in your Amazon Web Services (AWS) environment. This post shows you how. As you adopt post-quantum cryptography, one of the first decisions you face is which algorithms and parameter sets fit your business needs, balancing security against signature size, key […]

Software supply chain attacks have grown in both frequency and sophistication. Recent high-profile compromises of build systems and open source dependencies demonstrate that attackers increasingly target the trust mechanisms that verify software integrity. Those trust mechanisms rely on digital signature algorithms, and today many use traditional algorithms such as Rivest-Shamir-Adleman (RSA) and the Elliptic Curve […]
