Acronis cPanel Backup Plugin Vulnerability Exploited in Targeted Attacks

Acronis warns CVE-2026-87886, a local privilege escalation flaw in its cPanel/WHM and Plesk backup plugins, is exploited in targeted attacks.

Acronis disclosed CVE-2026-87886 (CVSS 7.8), a high-severity local privilege escalation caused by insecure file permissions in its Backup plugin for cPanel & WHM and Backup extension for Plesk on Linux. Affected versions include cPanel & WHM plugin builds before 1.9.3.1021 (fixed in 1.9.3 HF3) and Plesk extension builds before 1.8.11.638. A low-privileged attacker could escalate permissions and potentially run arbitrary code, impacting confidentiality and integrity of the application. Acronis says exploitation has been detected in the wild in limited, targeted attacks, but has not identified the attackers, timing, or objectives.

New Mirai-Based Evooo1Bot Botnet Targets Linux Devices

FortiGuard Labs disclosed Evooo1Bot, a Mirai-based Linux botnet active since July 2026 that hijacks routers and IoT devices for DDoS, credential theft, and SOCKS5 proxying.

Fortinet's FortiGuard Labs disclosed Evooo1Bot, a previously undocumented Linux botnet active since July 2026 that reuses Mirai's DDoS engine while adding encrypted C2, SSH brute-force scanning, credential sniffing, and SOCKS5 proxy modules. The bot exploits 18 known CVEs across Alcatel, NETGEAR, Tenda, D-Link, Telesquare, and Mitsubishi devices, some dating back to 2007, and communicates exclusively over port 443 to blend with HTTPS traffic. Compromised hosts can be turned into SOCKS5 relays for anonymous traffic forwarding or monetization via proxy services. The malware uses AES-256-CTR, ChaCha20, and XOR obfuscation with a 28-command administration interface.

New Mirai variant adds stealth capabilities to notorious botnet code

FortiGuard Labs reports new Mirai-derived botnet Evooo1Bot actively exploits unpatched routers and edge devices, adding encrypted C2, stealthy SSH scanning, and proxying.

FortiGuard Labs has identified Evooo1Bot, a previously undocumented Linux malware based on the Mirai botnet code, which has been actively exploiting unpatched vulnerabilities in internet-facing hardware for at least a month. Targeted devices include routers and edge hardware from Alcatel, D-Link, Mitsubishi Electric, Netgear, Tenda and Telesquare, with telemetry showing activity in North and South America, Europe, India, China and Japan. Beyond Mirai's usual DDoS functions, the variant adds encrypted C2 communications, a honeypot-aware SSH scanner, a sniffer for unchanged default credentials, and abuse of the SOCKS protocol to turn compromised devices into persistent proxies for concealing origin and pivoting into internal networks.

Evooo1Bot Linux Botnet Exploits Known Flaws to Turn Edge Devices Into SOCKS5 Proxies

Fortinet researchers documented Evooo1Bot, a new Mirai-derived Linux botnet active since July 2026 that exploits known edge-device flaws to build SOCKS5 proxy networks.

Fortinet FortiGuard Labs identified Evooo1Bot, a previously undocumented Linux botnet built on the leaked Mirai source code, active in the wild since July 2026 and targeting internet-facing edge devices. It exploits numerous known CVEs in routers and devices from D-Link, Tenda, Telesquare, Zyxel, Hikvision, Atlassian Confluence, WSO2, TP-Link, NETGEAR, and others, delivering a bot binary via a wget.sh loader from 91.92.40.118 that clears bash history. The bot offers encrypted C2 on port 443, SSH brute-force scanning, credential sniffing, DDoS over DNS/TCP/UDP, an HTTP exploit dispatcher, and converts infected hosts into SOCKS5 proxies for anonymizing follow-on operations.

From 88 lines to 1: Detecting DLL hijacking with Elastic Defend

Elastic condenses 88 lines of detection logic into one Elastic Defend 9.5.0 rule catching the DLL hijacking used by a ClickFix campaign.

The ClickFix campaign side-loads a malicious mscoree.dll next to a signed Microsoft binary and also ships a driver to kill Elastic Endpoint. Elastic rebuilt the DLL as a NativeAOT library, dropped it beside the signed binary, and confirmed that Elastic Defend 9.5.0 flags the load. The post replaces 88 lines of detection logic with a single rule for DLL search-order hijacking.

Memory-safety defects in the upstream (abandoned) AOSP OpenCORE AAC decoder, shipped unpatched by Samsung TizenRT

Abandoned AOSP OpenCORE AAC decoder has out-of-bounds-write and wild-pointer flaws reachable from attacker-controlled frames, unpatched in Samsung TizenRT.

The OpenCORE AAC decoder in AOSP's abandoned external/opencore tree contains memory-safety defects of the out-of-bounds-write and wild-pointer class. The code is still vendored and built by multiple projects, most notably Samsung's widely deployed TizenRT embedded RTOS. The defects are reachable from untrusted media because an AAC frame is attacker-controlled. The researcher is requesting a CVE ID for the issue.

WireGuard-Linux Stack-Based Buffer Overflow in lsiio (Linux IIO Userspace Tool) Due to Unbounded fscanf

The Linux IIO userspace tool lsiio has a stack buffer overflow in find_type_by_name() caused by unbounded fscanf reads of oversized filesystem-backed attribute values.

A stack-based buffer overflow exists in the Linux Industrial I/O (IIO) userspace utility lsiio. In the find_type_by_name() function, the program reads an unbounded string from a filesystem-backed attribute into a fixed-size stack buffer using fscanf("%s", ...). A crafted or oversized attribute value causes a write beyond the bounds of the destination buffer. Despite the title's reference to WireGuard-Linux, the flaw described is in the IIO lsiio utility.

Plug 'n' Pray: Agentic LLM-based Detection of Potential Log File Exposures in Third-Party Content Management System Plugins

Agentic LLM analysis validates 79 log file exposures across 62 of the 300 most-installed WordPress plugins, covering 250M+ active installations.

Researchers built an agentic LLM-based framework combining static and dynamic analysis to automatically detect insecure log files created by WordPress plugins. Scanning the 300 most-installed plugins, which account for roughly 75% of all active installations in the official ecosystem, it produced 81 findings with 79 manually reproduced across 62 plugins. Insufficiently secured log files can disclose credentials and personal data and have led to website compromises. The authors derive a taxonomy of log path and protection patterns and best practices, finding multi-layered protection often absent.

LLM Agents as Computational Typologists

AUTOTYPOLOGIST is an LLM agent that performs evidence-grounded linguistic typology analysis over 25 open-source reference grammars.

The agent retrieves relevant grammar sections, analyzes interlinear glossed text (IGT), and iteratively reasons over typological hypotheses in a ReAct-style workflow. It was evaluated on typological feature coding against expert annotations and hypothesis testing against universals using 25 open-source reference grammars. Results suggest LLM agents can support scalable, inspectable crosslinguistic analysis but still require expert validation.

Molecular Déjà Vu: Digit-Level Retrieval of Published Values in Frontier Language Models

Audit of 22 frontier models finds widespread verbatim retrieval of published molecular property values, with higher reasoning increasing recall of memorized numbers.

An arXiv audit tests 22 frontier LLMs across 12 molecular regression benchmarks for verbatim retrieval of published values. More than 50% of the LLMs show verbatim retrieval on five datasets, and identical experiments are flagged 89% more often at a high reasoning level than at the lowest one. Suppressing retrieval moves model prediction errors closer together in relative terms, suggesting predictive capability is not determined solely by memorized values.
