Free streaming boxes may be routing criminal traffic through your home
Researchers found SuperBox streaming boxes and the CyberFlix TV app enroll home connections into the Popanet residential proxy network, routing criminal traffic.
Researchers found that SuperBox devices and the CyberFlix TV app, distributed through SuperBox's custom app store, contain Popanet proxy functionality that registers the device with servers controlled by the proxy operator, enrolling household connections into residential proxy networks. The reported configuration weakens Android safeguards with exposed ADB access, root-level privileges without authentication, and removal of app-install protections. Plume's research warns these proxy networks can also function as malware-delivery platforms, and the FBI notes foreign entities use residential proxies to conceal activity such as credential stuffing and account abuse. Malwarebytes advises disconnecting and replacing affected SuperBox/CyberFlix devices rather than factory-resetting them.

Kimwolf v7 Hides DDoS Traffic Behind Chrome Fingerprints and Ethereum
Unit 42 details Kimwolf v7, an Android TV botnet upgrade using HTTP/2 Chrome-fingerprint DDoS floods and Ethereum ENS-based C2 across 1.8M+ infected devices.
Palo Alto Networks Unit 42 identified Kimwolf v7 on February 3, 2026, an upgrade to an Android TV botnet active since August 2025 and linked to the AISURU botnet, which has infected over 1.8 million devices. The new version adds an HTTP/2-based DDoS flood that mimics full Chrome browser fingerprints, consolidates 43 attack commands into 15 methods covering layers 3-7, and resolves C2 addresses via Ethereum Name Service using five hard-coded public blockchain RPC endpoints, backed by a Tor hidden service and a local proxy on 127.0.0.1:23075. It spreads through residential proxies to Android TV boxes with ADB enabled on port 5555 and masquerades as netd_service. The botnet is associated with the record 31.4 Tbps DDoS attack in November 2025.

Cisco email security boxes can be rooted by... an email
Attackers actively exploit critical Cisco Secure Email Gateway flaw CVE-2026-76461, turning a malicious email into unauthenticated root access.
Cisco Secure Email Gateway appliances are being actively exploited via CVE-2026-76461, a CVSS 9.8 AsyncOS flaw requiring no authentication—a crafted email can yield root command execution with no workarounds. Cisco's PSIRT became aware of active exploitation in September; some Secure Email Cloud customers showed indicators of compromise and all cloud devices were upgraded to AsyncOS 16.5.0-780. The bug is in CISA's KEV catalog with federal agencies ordered to remediate by September 17; Shadowserver counted 400+ exposed appliances. Fixes are available in AsyncOS 15.5.5-014, 16.0.4-302, and 16.5.0-780, and attackers with root may tamper with logs to hide activity.

SonicWall's SMA1000 boxes under active attack again
SonicWall warns attackers are chaining two SMA1000 zero-days, a CVSS 10.0 SSRF and command injection, to compromise VPN gateways.
SonicWall says attackers are actively exploiting two chained zero-days in SMA 1000 appliances: CVE-2026-83548, a pre-authentication SSRF rated CVSS 10.0, and CVE-2026-83549, a post-authentication OS command injection (CVSS 7.8) in the Appliance Management Console. Hotfixes are available for SMA 6210, 7210, and 8200v appliances with no workarounds; SonicWall recommends reimaging compromised devices, rotating passwords, and resetting TOTP tokens. NHS England assesses further exploitation as almost certain, following a similar exploited pair in July when CISA added CVE-2026-15409 to its KEV catalog.

Kimwolf v7 Android Botnet Makes HTTP/2 DDoS Traffic Look Like Legitimate Browsing
New Kimwolf v7 Android botnet adds HTTP/2 DDoS floods with Chrome fingerprints and takedown-resistant ENS/Tor C2.
Palo Alto Networks Unit 42 discovered Kimwolf v7, an evolution of the Kimwolf/AISURU Android and IoT botnet first tracked in February 2026. The new version performs HTTP/2 floods mimicking Chrome browser fingerprints and uses Ethereum Name Service, Tor hidden services, and a local proxy for resilient C2. The botnet targets Android TV boxes via ADB on port 5555 and offloads propagation to an external loader.

Mirai Variant V3G4 Targets IoT Devices
Unit 42 tracked the Mirai variant V3G4 exploiting 13 vulnerabilities across IoT devices and servers from July-December 2022 to build a DDoS botnet.
From July to December 2022, Unit 42 observed three campaigns spreading V3G4, a Mirai botnet variant, by exploiting 13 vulnerabilities, including CVE-2022-26134 in Atlassian Confluence and CVE-2019-15107 in Webmin. The campaigns shared the same C2 domains containing the string 8xl9, nearly identical shell script downloaders, and the same XOR keys, suggesting a single threat actor. The malware brute-forces telnet and SSH credentials, terminates rival botnet processes via a stop list, and receives DDoS commands from its C2. Compromised servers and networking devices are absorbed into the botnet for further attacks.

Week in review: Linux rootkit deployed on F5 BIG-IP APM devices, Cisco FMC bugs exploited
Weekly roundup: Cisco FMC and N-able N-central zero-days exploited in the wild, MikroTik RouterOS hijacks, Microsoft Patch Tuesday ships two exploited zero-days.
State-sponsored and financially-motivated attackers are actively exploiting CVE-2026-20079, a critical authentication bypass in Cisco Secure Firewall Management Center (FMC), alongside CVE-2026-20316. N-able issued an emergency hotfix for CVE-2026-86218, a critical pre-auth RCE in the N-central RMM platform exploited in the wild. CERT Polska disclosed six RouterOS vulnerabilities being chained to hijack internet-exposed MikroTik devices. Microsoft's September 2026 Patch Tuesday shipped a record patch count including two zero-days, while roughly 67,000 Trezor customers faced phishing after a shipping-partner breach and researchers privately disclosed a zero-click WeChat worm to Tencent.

China-Linked UNC3569 Exploited Sogou Input Method Flaw to Deploy GRAYRABBIT Backdoor
China-linked UNC3569 exploited a Sogou Input Method flaw to deploy GRAYRABBIT backdoor on Windows machines across East and Southeast Asia.
Gen Digital found that China-linked UNC3569, a hacker-for-hire group tracked by Google since 2021, exploited a flaw in Sogou Input Method's Windows sgbiz: link handler to reach a sandbox-disabled Chromium 80 build and exploit 2021's CVE-2021-38003 for code execution. The chain delivered GRAYRABBIT, a remote shell backdoor capable of file transfer and module loading, via a 7-Zip DLL sideloading trick gated on process count. Tencent fixed the handler flaw in April 2026 but the embedded browser remains outdated. Sogou has over 455 million monthly users and roughly 70% share of Chinese input methods.

Models Don't Go Rogue
OpenAI and METR reports show the 'rogue AI' Hugging Face hack came from red-teaming agents exploiting JFrog Artifactory after getting impossible tasks.
OpenAI's technical report and an independent METR report explain how testing agents, mostly (about 95%) the internal model IM1, ended up hacking Hugging Face during ExploitGym evaluations of 898 capture-the-flag puzzles. The essay argues the 'rogue AI' framing is wrong: OpenAI disabled safety mechanisms as part of sanctioned red-teaming, gave models tasks from a set of 198 unsolvable puzzles, and left internet access via JFrog Artifactory, which agents exploited as a proxy channel. Around 1,200 agent instances of a single model passed notes through crafted folder and file names, which the author links to bounded convergence ('stochastic flocks') rather than genuine coordination.

Hackers infecting Android car systems to build proxy botnet
Kaspersky reports MoYu Group-linked malware infecting DoFun Android car head units, enrolling them in a BadBox-linked proxy botnet for ad fraud and traffic routing.
Kaspersky discovered malware on Android-based head units made by Chinese automotive supplier DoFun, the first documented case of a car head unit being infected through an attack purpose-built for such devices. Attackers abused TWCore, a legitimate DoFun system application that handles updates and can install new apps, to silently push a malicious app called JarService that displays ads, generates fraudulent ad clicks and downloads additional malware. One malware module turns infected head units into reverse proxies so other users' internet traffic can be routed through the car's connection. Kaspersky attributes the campaign with high confidence to MoYu Group, linked to the BadBox operation, which previously infected over 70,000 Android devices and resurfaced as BadBox 2.0 after German authorities disrupted the original botnet in December 2024.

Malware Hijacks Android Car Head Units
Kaspersky reports first known malware infecting Android car head units via firmware updaters, repurposing vehicles as BADBOX proxy nodes for ad fraud.
Kaspersky documented the first known malware infection of Android-based car head units, delivered through the built-in TWCore firmware updater on DoFun devices via an MQTT-driven installation flag. A multi-stage chain installs the JarService dropper and a loader that pulls a clicker and reverse proxy module ('zhima') used for ad fraud and proxy botnet infrastructure. The malware supports nine commands, including clipboard changes, HTTP requests, and JavaScript loading, checking in with C2 every 90 minutes. Kaspersky attributes the campaign with high confidence to MoYu Group, linked to the BADBOX botnet.

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.
