Echo: Learning-based Matching Decompilation using Trusted Back Translation

Researchers introduce Echo, a matching decompiler using trusted back-translation that roughly doubles exact-match rates and outperforms GPT-5.6 and Codex on Mirai.

Echo performs matching decompilation by using compilation as trusted feedback for iterative search: a domain-specific model generates candidate code and compilation configurations, which are recompiled, compared at assembly level, and repaired via rule-based rewriting, neural refinement, and reasoning-based refinement. On function-level benchmarks, Echo produces 2.43x more exact matches than the strongest baseline and the highest structural similarity to ground truth. On the Mirai malware binary, it matches 2.75x and 7.4x as many functions as GPT-5.6 and Codex, respectively.

BambooToken: The Malware That Speaks MQTT to Stay Under the Radar

Lumen's Black Lotus Labs uncovered BambooToken, a Windows and Linux malware family using MQTT broker-based C2 and DLL sideloading across Asia since February 2023.

Lumen Black Lotus Labs identified BambooToken, a multiplatform malware family that exchanges commands through MQTT brokers so infected hosts never contact the C2 server directly, active from at least February 2023 through July 2026. The Windows variant sideloads via Tendyron's OnKey hardware-token software used in Chinese banking and government, or impersonates Kingsoft Office, without either vendor's signing certificate being compromised; a Linux build appeared by December 2025 with shell, file transfer, and system information commands. Victims include MikroTik and DrayTek routers in Singapore, Cambodia, and Vietnam reached after internet-wide SNMP scanning, and Lumen cannot attribute the family to any known actor.

BlackHatSect0r Hackers Disable AI Safety Controls to Automate Credential Theft and Cyberattacks

French-speaking crew BlackHatSect0r disabled AI agent safety controls to automate scanning, credential harvesting, and vishing, exposing 16,834 stolen credentials.

Socradar researchers analyzed the exposed infrastructure of a French-speaking crew called BlackHatSect0r && DXQRTXX, which ran a Nous Research Hermes agent on a DeepSeek model with safety controls removed via HERMES_DISABLE_SAFETY=1. A custom Go-based C2 platform, DXSCAN, was exposed on port 8080 with over 200 secret-detection patterns, a vault of 16,834 harvested credentials, and scanning activity queuing 2.75 million domains and reaching more than 726,000 hosts. The kit also held a database of roughly 450,000 French telecom subscriber records used to prepare vishing lures impersonating Société Générale, plus JWT-forging tooling for a cryptocurrency exchange. Most confirmed compromises relied on exposed secrets and cloud misconfiguration rather than novel exploits; the one cited vulnerability, CVE-2026-42530, is an NGINX HTTP/3 QPACK use-after-free fixed in version 1.31.2.

Jenkins Patches 20 Plugin Flaws Leading to RCE, XSS and Credential Theft

Jenkins patched 20 vulnerabilities across 13 plugins, including Groovy sandbox bypasses enabling remote code execution on CI/CD controllers.

Jenkins released security updates on September 16, 2026 for 20 vulnerabilities across 13 plugins, including nine fixes in the Script Security Plugin for Groovy sandbox bypasses. CVE-2026-92127 (classpath abuse) and CVE-2026-92128 (TOCTOU race on remote JAR loading) could allow arbitrary code execution in the controller JVM, exposing build secrets, credentials, and downstream deployment environments. Other flaws include stored XSS in the Warnings, Coverage, OWASP Dependency-Check and Gitee plugins, SSRF in the Gradle and Bitbucket plugins enabling credential capture, credential exposure via CVE-2026-92130, arbitrary file write via CVE-2026-92137, OAuth token theft, and an open redirect in the Keycloak Authentication Plugin. No exploitation is reported; fixes include Script Security Plugin 1422.v06869826dd9b_.

Autonomy in Check: Governor-Mediated Adaptive Security at the Edge

Split-control architecture adds a deterministic governor to validate LLM and rule-based planner intents before eBPF enforcement at the edge.

Researchers propose a split-control edge security architecture in which an untrusted planner emits typed security intents that a deterministic governor checks against safety, resource, temporal-stability, and proportionality invariants. Admitted actions are bound to signed receipts and compiled into pre-installed eBPF map updates. A Raspberry Pi 5 prototype on a university 5G test network admitted, rejected, and bounded intents at microsecond cost.
