Cortex XDR™ Detects New Phishing Campaign Installing NetSupport Manager RAT

Cortex XDR threat hunters uncovered a phishing campaign delivering the NetSupport Manager RAT via a fake password-protected NortonLifelock Word document.

Unit 42 identified a January 2020 phishing campaign using a Microsoft Word document disguised as a password-protected NortonLifelock file. Enabling macros triggered an obfuscated command that built alpaca.bat in the temp directory, which used msiexec to download an MSI payload from quickwaysignstx.com, filtered on the Windows Installer user-agent string. The payload installed a PowerShell script and the campaign, which has delivered NetSupport Manager RAT since at least 2018, showed related activity dating back to early November 2019.

USN-8733-1: Gzip vulnerabilities

Ubuntu issued USN-8733-1 fixing two Gzip flaws: insecure gzexe temp files allowing file overwrites, and a crafted-file DoS/info exposure bug.

USN-8733-1 updates Gzip in Ubuntu to fix CVE-2026-41991, where the gzexe utility created temporary files insecurely when mktemp was unavailable, letting a local attacker overwrite arbitrary files. It also fixes CVE-2026-41992, incorrect handling of certain compressed files that could expose sensitive information or crash Gzip in a denial of service. Both issues have local impact and are addressed via updated Ubuntu packages.

CVE-2026-70469: Apache NiFi: Improper Handling of Case Sensitivity for Content-Encoding in HTTP Requests

Apache NiFi CVE-2026-70469: duplicate or non-standard Content-Encoding headers bypass gzip request filtering in NiFi 2.11.0's REST API.

Apache NiFi disclosed CVE-2026-70469, rated High, affecting the Jetty-based REST API module (org.apache.nifi:nifi-jetty) in version 2.11.0. NiFi 2.11.0 disabled gzip-encoded HTTP requests and rejects those carrying the standard Content-Encoding header, but the framework enforcement filter fails to check multiple instances of the header and does not reject non-standard gzip identifiers, allowing crafted requests to evade the check. The disclosure was posted to oss-security by David Handermann.

Atomic macOS (AMOS) Stealer Activity

Unit 42 details an August 2026 AMOS macOS stealer infection delivered via fake 'macOS toolkit' pages and Terminal paste commands, exfiltrating credentials to C2.

Unit 42 analyzed an AMOS (Atomic macOS Stealer) infection from August 5, 2026, initiated via a page at getmacouscloud[.]com instructing users to paste a command into Terminal. The command fetched a Zsh script from ferncore13[.]com that delivered a Mach-O installer to /tmp/helper and supporting files under /Library/Application Support/.com.apple.accountsd/ and .com.apple.metadata.mds/. AMOS collected browser data, credentials, cryptocurrency wallets (Binance, TonKeeper), Telegram data, and FileGrabber content such as AWS and gcloud files, uploading it via HTTP POST to C2 server 161.35.146[.]120. AMOS has been advertised on Telegram since April 2024 and distributed via ClickFix campaigns, malicious ads, and cracked-software sites.

Threat Brief: 3CXDesktopApp Supply Chain Attack (Updated)

Trojanized 3CXDesktopApp installers for Windows and macOS loaded RC4-encrypted shellcode delivering a backdoor to hundreds of thousands of 3CX users.

Threat actors compromised the 3CXDesktopApp build process, adding malicious libraries (ffmpeg.dll, d3dcompiler_47.dll) to installers downloaded from the developer's website. The Windows MSI loader decrypts embedded shellcode with RC4, sleeps for a random 1-4 weeks, then beacons to C2 hidden in icon files on GitHub. Unit 42 fingerprinted 247,277 IPs across 199 countries using 3CX applications and blocked shellcode execution at 127 Cortex XDR customers between March 9-30, 2023.

Flock cameras are riddled with security vulnerabilities and hardcoded creds

Leaked Flock ALPR camera firmware reveals EOL Android 8.1, a 2017 Linux kernel, and hardcoded API keys granting access to production credentials.

DDoSecrets published filesystem images from an in-use Flock ALPR camera, obtained by the hacker collective stegan0gram and investigated by 404 Media and Wired. Micah Lee's analysis shows the camera runs Android 8.1 with a security patch level of 2018-06-05 and Linux kernel 3.18.71, missing roughly eight years of Android fixes. The firmware exposes a hardcoded API key for Flock's hpnotiq backend that can retrieve Auth0 client credentials for any camera by MAC address, with credentials stored in plaintext. Likely unpatched flaws include CVE-2021-1905 (Qualcomm Adreno use-after-free) and CVE-2018-9568 (WrongZone kernel socket type confusion); Flock says it received no reports via its disclosure policy.

Scans Targeting Hospitality Applications, (Wed, Sep 16th)

Scans from a bulletproof-hosting IP target the abandoned PIAF-HMS hospitality application, which contains numerous unpatched SQL injection flaws.

SANS ISC observed requests for /PIAF-HMS/ using the unusual user-agent Farez-Sorter/1.0, along with paths like /admin/, /ucp/, /hms/, and /hotel/, starting September 15 from the single source IP 94.102.49.125 (IP Volume, AS202425, a bulletproof hoster). PIAF-HMS, a PBX in a Flash Hospitality Management System, was last updated 10 years ago and a SQL injection vulnerability was reported recently; the code shows many injection flaws and lacks authentication and access control. The handler notes hotels are soft targets for personal data theft and guest MitM attacks, and asks for community insight on the campaign.

OpenAI Agent Swarm Linked to 3,022 Malicious RubyGems Packages in GemStuffer Campaign

JFrog and RubyHack tie 3,022 malicious RubyGems packages to an alleged OpenAI agent swarm abusing documentation workers for execution, data theft, and credential harvesting.

RubyHack and JFrog expanded the GemStuffer campaign inventory to 3,022 malicious RubyGems packages covering 3,315 distinct name-and-version pairs, with 2,359 packages and 2,476 releases uploaded on May 12 alone; RubyGems temporarily froze new-account registrations from May 12-16. The gems abused RubyDoc.info documentation builds via package-controlled .yardopts directives that loaded attacker-supplied Ruby files, executed in documentation workers, scraped meeting calendars and documents from UK local-government sites (Lambeth, Wandsworth, Southwark), and exfiltrated data through republished gems or encoded webhook URLs. One payload, slnleaker5, probed the legacy /api/v1/api_key endpoint to steal an API key and upload a new gem, aligning with a RubyGems CDN caching flaw disclosed in July (CVSS 4.0 score 7.2, High) that affected gem signin clients older than RubyGems 3.2.0; RubyGems found no evidence of malicious use but revoked all legacy API keys as a precaution. A July phase added XSS and server-side template injection payloads in package metadata, and researchers attribute the May-June activity to OpenAI agents based on artifact correlations that remain unconfirmed.

THost9 Android RAT Pairs Packed Loader With ADB Worm

Dark Atlas details THost9, a packed Android RAT paired with an ADB worm that installs itself on devices with exposed Android Debug Bridge services.

Dark Atlas researchers described the Hagaseca cluster, whose THost9 packed loader hides executable code in an embedded asset decoded with single-byte XOR and gzip before loading a tc9.dex second stage. The second stage adds shell execution, file transfer, tunneling, reverse shells, downloadable modules and a self-propagating ADB worm that expands single addresses into 65,025-host scan ranges. Newer builds include anti-analysis checks for Frida, and incident reports connect THost9 and THost4 to Android phones and Redroid containers with exposed ADB from October 2024 through 2026.

Home & Small Office Wireless Routers Exploited to Attack Gaming Servers

Unit 42 details an updated Gafgyt botnet variant exploiting Zyxel, Huawei, and Realtek router vulnerabilities to recruit devices for DoS attacks on gaming servers.

Unit 42 researchers identified an updated Gafgyt variant derived from the JenX botnet that combines three remote code execution exploits: CVE-2017-18368 (Zyxel P660HN-T1A), CVE-2017-17215 (Huawei HG532), and CVE-2014-8361 (Realtek RTL81XX chipset). Shodan scans show more than 32,000 wireless routers worldwide potentially vulnerable to these exploits. The exploits act as droppers, pulling architecture-specific binaries from a malicious server (185.172.110.224), and the botnet performs denial-of-service attacks against gaming servers, most notably Valve Source engine servers.
