Nonprofit that tracks meteors taken down by "critical blow" from a cyberattack

The International Meteor Organization says a cyberattack dealt a critical blow to its infrastructure, taking much of its site offline for weeks.

The International Meteor Organization (IMO), a nonprofit coordinating amateur and professional meteor observations since 1988, reported a cyberattack that took much of its website offline. The organization expects several weeks of partial downtime while transitioning to new infrastructure and is prioritizing fireball reporting through alternate channels. The attack vector and whether any data was accessed remain undisclosed; the IMO's observation databases and WGN journal are widely used in the field.

Malware bypasses browser checks to force install Chrome, Edge extensions

Elastic Security Labs detailed KREMLIN, a Brazilian banking malware that silently installs malicious Chrome and Edge extensions, with 1,515 confirmed infections.

Elastic Security Labs analyzed KREMLIN, a toolkit used by a Brazilian operation in at least seven campaigns since May 2025 that impersonates 12 banks to trick users into opening a JavaScript file disguised as a bank receipt or invoice. After anti-sandbox checks, it downloads Node.js, persists via a scheduled task, and fetches payload locations from an Ethereum smart contract, hiding payloads in JPEG images on Internet Archive. The toolkit bypasses Chromium integrity mechanisms to install unapproved Chrome/Edge extensions masquerading as AVSync that steal cookies, keylog form input, capture screenshots, and intercept HTTP traffic, while recent campaigns deployed the REMCOS RAT and earlier ones Pulsar RAT. Elastic confirmed 1,515 infected systems, almost all in Brazil, and disrupted the campaign by registering an anti-sandbox canary domain; the linked wallet handled roughly 20,800 USDT incoming and 19,000 USDT outgoing.

Three Threat Groups Target Russian Enterprises With Backdoors, Ransomware, and Wipers

Kaspersky details NightEagle, Hacking Cat, and Toy Ghouls targeting Russian enterprises with Exchange backdoors, Gorilla RAT, and destructive Monkey ransomware.

Kaspersky reports three threat clusters targeting Russian enterprises: NightEagle (APT-Q-95), the pro-Ukrainian hacktivist group Hacking Cat, and Toy Ghouls. NightEagle uses compromised VPN credentials and the GhostContainer modular backdoor to fully compromise Microsoft Exchange servers, chaining CVE-2020-0688 exploitation, BlueKeep (CVE-2019-0708), Active Directory vulnerabilities, and DCSync to seize domain controllers. Hacking Cat exploits Exchange flaws including CVE-2021-26855 and CVE-2026-42897 to deliver the Gorilla RAT and multiple Monkey ransomware variants written in Rust, .NET, C++, and Golang targeting Windows, Linux, and VMware ESXi, with some variants acting as wipers that never store the encryption key.

Operation RapidRust: APT36 Deploys RUSTYSHADE, RUSTYMOVE, PSNATCH, and BASHNATCH

Zscaler details Operation RapidRust: APT36 deploys four new tools including RUSTYSHADE, a Rust backdoor using private GitHub repos for encrypted C2.

Zscaler ThreatLabz documents Operation RapidRust, a campaign by Pakistan-aligned APT36 deploying four new tools: RUSTYSHADE, a 64-bit Rust Windows backdoor that uses attacker-controlled private GitHub repositories with a hardcoded PAT and AES-256-GCM-encrypted messages for C2; RUSTYMOVE; PSNATCH, a PowerShell file stealer that scans Office documents, archives, media, and databases modified in the last 120 days and exfiltrates up to 5 GB per run to per-machine GitHub repositories; and BASHNATCH. The backdoor was dropped via PowerShell from attacker-controlled Backblaze B2 storage and supports screenshots, webcam capture, file listing, downloads, and shell command execution.

Hackers Can Rent VectraRAT for $250 a Month to Take Control of Windows PCs

SOCRadar uncovered VectraRAT, a previously undocumented $250-per-month Windows RAT rental service delivered via Amadey and ClickFix lures.

SOCRadar's Threat Research Unit identified VectraRAT, a rental-only remote access trojan sold by a developer known as Vectra (formerly Nyxel), after an exposed online directory revealed samples, licenses, and operator logs across ten-plus servers. The toolkit includes a Linux control server, Windows implant, payload builder, and VectraHub panel, enabling hidden desktop access, keylogging, command execution, credential theft, file transfer, proxying, and silent privilege escalation. Of victims with OS data, 48 percent ran corporate Windows editions, and researchers recorded 38 genuine victim sessions in under a week, including file theft from business systems. Distribution occurs through the Amadey loader and ClickFix pages impersonating TurboTax, with custom TCP-based C2 over non-standard ports.

Critical Issabel PBX Command Execution Vulnerability Exploited in the Wild

Unauthenticated attackers exploit CVE-2026-89026 in Issabel PBX via forged JWT tokens to run OS commands; exploitation observed since September 9.

CVE-2026-89026 (CVSS v4 9.3) stems from a hard-coded HS256 JWT signing key in Issabel Framework's pbxapi/index.php, letting unauthenticated attackers forge bearer tokens and execute OS commands through the Asterisk Manager Interface originate endpoint. Issabel Framework versions before commit b97dbaf0b71c1c36f841e672b664afbeb02773bd are affected. Shadowserver Foundation first observed exploitation on September 9, 2026, and VulnCheck added the flaw to its Known Exploited Vulnerabilities database.

Acronis backup plugin flaw exploited in targeted attacks (CVE-2026-87886)

Acronis warns CVE-2026-87886, an authenticated Linux privilege escalation flaw in its cPanel, WHM, and Plesk backup plugins, is under limited targeted exploitation; patches released.

Acronis disclosed CVE-2026-87886, a privilege escalation vulnerability caused by insecure file permissions in its backup plugins for cPanel, WHM, and Plesk, platforms popular among hosting providers and MSPs. Exploitation has been detected in the wild in limited, targeted attacks against cPanel & WHM deployments, with no exploitation observed on Plesk so far, and the low-complexity attack requires no user interaction. Fixes shipped last week: backup plugin version 1.9.3 HF3 for cPanel & WHM and extension version 1.8.11 for Plesk.
