AWS Bedrock Sandbox Allows DNS-Based Isolation Bypass

🔒 BeyondTrust researchers demonstrated that the Sandbox mode in AWS Bedrock AgentCore Code Interpreter permits outbound DNS A/AAAA queries that can be abused to create a bidirectional covert channel. By encoding data in DNS requests and responses they showed both data exfiltration and an interactive reverse shell without triggering network restrictions. AWS reproduced the report but characterized the behavior as intended and updated documentation rather than issuing a patch.

CISA: BeyondTrust RCE Now Exploited in Ransomware Attacks

🔒 CISA warns that CVE-2026-1731, a pre-authentication remote code execution flaw in BeyondTrust Remote Support and Privileged Remote Access, is being actively exploited in ransomware attacks. The issue is an OS command injection reachable via specially crafted client requests and was added to the Known Exploited Vulnerabilities catalog on February 13. BeyondTrust reports the cloud (SaaS) was auto-patched on February 2; self-hosted customers must enable updates or install Remote Support 25.3.2 or Privileged Remote Access 25.1.1 and later.

Critical Pre-auth RCE in BeyondTrust Remote Support

🚨 On Feb. 6, 2026, BeyondTrust published an advisory for CVE-2026-1731, a critical pre-auth remote code execution vulnerability affecting BeyondTrust Remote Support and some Privileged Remote Access deployments. The flaw allows unauthenticated attackers to inject shell commands via the WebSocket remoteVersion field during the handshake, resulting in OS command execution as the site user. Unit 42 observed active exploitation that included web shells, C2 traffic, account tampering and data theft. Immediate patching for self-hosted appliances and engagement of incident response if compromise is suspected are recommended.

Weekly Recap: Add-in Hijack, Zero-Days, and Cloud Abuse

🔒 This weekly recap shows how small, trusted gaps are becoming major entry points — from a hijacked Outlook add-in (AgreeTo) turned into a phishing kit that stole over 4,000 Microsoft credentials to multiple actively exploited zero-days in Chrome and Apple platforms. It also covers a critical BeyondTrust RCE under active exploitation, new Linux botnet activity abusing SSH, and cloud-focused campaigns targeting exposed Docker, Kubernetes, and Redis instances. Attackers are combining legacy techniques, cloud misconfigurations, and AI assistance to scale access and persistence.

CISA orders federal agencies to patch BeyondTrust bug

🔒 CISA has ordered federal agencies to secure on‑premises BeyondTrust Remote Support and Privileged Remote Access instances within three days after disclosure of a critical remote code execution flaw (CVE-2026-1731) that is being actively exploited. The OS command injection allows unauthenticated attackers to run system commands and could lead to data exfiltration or service disruption. BeyondTrust patched SaaS instances on Feb 2; on‑premise customers must install fixes manually.

Critical BeyondTrust RS Flaw Being Exploited in Wild

🔒 Researchers warn a critical pre-authentication command injection (CVE-2026-1731) in BeyondTrust Remote Support is being actively exploited to compromise self-hosted deployments, including legacy Bomgar B-series appliances. Attackers have deployed renamed SimpleHelp binaries, created domain accounts and escalated privileges to perform lateral movement. Patches are available, but end-of-life appliances and required version upgrades complicate remediation while a public proof-of-concept has accelerated exploitation.

CISA Adds Known-Exploited CVE for BeyondTrust RS/PRA

⚠️ CISA has added CVE-2026-1731 to its Known Exploited Vulnerabilities (KEV) Catalog after confirming active exploitation of an OS command injection vulnerability affecting BeyondTrust Remote Support (RS) and Privileged Remote Access (PRA). CISA emphasizes that command injection flaws are a frequent and dangerous attack vector that pose significant risk to the federal enterprise. Under BOD 22-01, Federal Civilian Executive Branch agencies must remediate KEV entries by the specified due date; CISA strongly urges all organizations to prioritize timely remediation and integrate these fixes into their vulnerability management processes.

Researchers Observe In-The-Wild Exploitation of BeyondTrust

🔴 watchTowr reported the first in-the-wild exploitation of a critical BeyondTrust vulnerability, CVE-2026-1731, with attackers abusing the get_portal_info endpoint to extract the x-ns-company value before establishing a WebSocket channel. The flaw (CVSS 9.9) allows unauthenticated remote code execution by sending specially crafted requests and has been patched in Remote Support (BT26-02-RS, 25.3.2+) and Privileged Remote Access (BT26-02-PRA, 25.1.1+). The rapid weaponization highlights how quickly defenders must patch critical systems. CISA also added four actively exploited flaws to its KEV catalog and set federal remediation deadlines in February and March 2026.

Preparing for the Digital Battlefield of Identity Risk

🔒 BeyondTrust's 2026 predictions argue that the next major breaches will stem from unmanaged identity debt rather than simple phishing. The report highlights three identity-driven threats: agentic AI acting as privileged deputies vulnerable to prompt manipulation, automated "account poisoning" in financial systems, and long-dormant "ghost" identities surfacing in legacy IAM. The authors recommend an identity-first posture with strict least-privilege, context-aware controls, real-time auditing, and stronger identity governance.
