Adobe Patches Magento Zero-Day Exploited to Deploy Rust Backdoor and PHP Web Shell

Adobe patches actively exploited Magento zero-day CVE-2026-75650 (CVSS 10.0), abused since Sept 4 to deploy a Rust backdoor and PHP web shells.

Adobe released an emergency hotfix (VULN-39341) for CVE-2026-75650 (CVSS 10.0), dubbed StyleSmuggler by Sansec, which abuses Magento's template system via PHP code injection to trigger unauthenticated remote code execution in Adobe Commerce and Magento Open Source. Exploitation began September 4, 2026, with attackers deploying a Rust-based Linux backdoor and a PHP dropper that writes a web shell; one managed server was compromised 50 minutes after the first report. Previdian honeypots recorded 12 exploitation attempts from two unique IPs in China and Romania since September 7, all unsuccessful. Adobe urges merchants to apply the patch and rotate encryption keys.

Artifactory flaws chained in attacks deploying backdoor malware

Attackers chain JFrog Artifactory flaws CVE-2026-42018 and CVE-2026-42016 to gain admin tokens and deploy a Rust backdoor on self-hosted servers.

Wiz observed multiple threat actors chaining CVE-2026-42018 and CVE-2026-42016 against self-hosted JFrog Artifactory instances between August 15 and September 8, 2026, in some cases obtaining admin access in under five minutes. The critical authentication bypass CVE-2026-82329 was also exploited this month to mint administrator tokens. Attackers installed malicious Groovy plugins, dropped a Rust backdoor with C2 capabilities, uploaded webshells, stole configuration data and cluster join keys, and added SSH keys to new accounts. Wiz estimates 49-62% of internet-reachable Artifactory instances are vulnerable to at least one of the three flaws, and patched releases from 7.111.21 through 7.161.20 are available.

StyleSmuggler: The Magento Zero-Day Behind New Store Attacks

Sansec reports actively exploited Magento/Adobe Commerce zero-day StyleSmuggler enabling unauthenticated RCE and Rust backdoor installation on fully patched stores since September 4.

Sansec discovered StyleSmuggler, an unpatched zero-day in Magento Open Source and Adobe Commerce, affecting all current versions including 2.4.7, 2.4.8 and 2.4.9, with attacks observed since September 4. The two-stage attack poisons Magento's template system via the styles property and executes the injected PHP during 'Payment Transaction Failed Reminder' email rendering, working even when email delivery fails and when sessions are moved to Redis. Successful compromise installs a lightweight Rust backdoor disguised as fc-cache or chronyd that beacons every 60 seconds with 48-byte UDP packets to NTP port 123 at ntp.timesync.to. A second attacker deployed a PHP web shell in product-image cache directories, hidden behind 404 responses unless a correct X-Cache-Token header is present.

Adobe Commerce max-severity bug comes under active attack

Attackers are actively exploiting CVE-2026-75650 (CVSS 10.0), an unauthenticated RCE zero-day in Adobe Commerce/Magento, deploying a Rust backdoor on e-commerce servers.

Sansec identified active exploitation of a CVSS 10.0 zero-day (CVE-2026-75650) in Adobe Commerce and Magento Open Source versions 2.4.4 through 2.4.9, dubbed StyleSmuggler. The attack abuses crafted style properties in Magento template processing to execute PHP while rendering a 'Payment Transaction Failed Reminder' email, then launches a Rust backdoor connecting to C2 at 99.84.67.186 disguised as NTP traffic. Exploitation began September 4, 2026; Adobe released emergency hotfix VULN-393411, but Sansec also observed a second attacker deploying a PHP web shell in the product-image cache.

Adobe Commerce Zero-Day Exploited to Backdoor Online Stores

Sansec found attackers exploiting an Adobe Commerce/Magento zero-day (StyleSmuggler) since September 4 to deploy Rust backdoors on online stores.

Threat actors are actively exploiting a zero-day RCE in Adobe Commerce and Magento 2.4.7-2.4.9, injecting PHP code via generated failure reports and executing it through Magento's payment-failure email, with no user interaction required. Exploitation began September 4 and succeeds even against stores running the July and August 2026 patches; the Rust backdoor disguises itself as kworker/u:8:0 or fc-cache and hides C&C communication inside fake NTP replies. Adobe's September 8 Patch Tuesday updates may not include a StyleSmuggler fix.

Magento StyleSmuggler zero-day exploited to deploy Linux backdoor

StyleSmuggler zero-day in Magento and Adobe Commerce is actively exploited in the wild to deploy a Rust-based Linux backdoor; fix not yet released.

A zero-day dubbed StyleSmuggler affecting all versions of Magento and Adobe Commerce is being actively exploited, with the first observed incident on September 4 on a fully patched site. The exploit injects PHP code via Magento's template system through a fake 'failed-payment' email to achieve code execution, installing a Rust-based backdoor disguised as kworker/u:8:0 or fc-cache with a 30-minute cron job for persistence. The backdoor communicates via TLS/WebSockets or UDP port 123 masquerading as NTP traffic, checks TracerPid to detect tracing, and can receive remote commands. Adobe confirmed it is working on a fix with no timeline; Sansec recommends disabling GraphQL as mitigation and monitoring for suspicious cron entries and kworker or fc-cache processes. Magento is installed on more than 160,000 websites, including 14,000 of the top 1 million sites.

C2Looper: A New Backdoor Likely Tied To Ransomware With GitHub C2

Zscaler ThreatLabz identified C2Looper, a new Rust-based backdoor likely tied to ransomware actors and delivered via ClickFix chains, using GitHub for C2.

In July 2026, Zscaler ThreatLabz identified C2Looper, a new Rust-based backdoor family. The malware supports arbitrary command execution, reconnaissance, and deployment of second-stage payloads, and uses GitHub as its command-and-control channel. ThreatLabz assesses with low-to-medium confidence that it is delivered through multi-stage ClickFix infection chains and is likely leveraged by a ransomware-related threat actor. The analysis covers multiple C2Looper variants, their network protocols, and capabilities.

Attackers Turn Trusted Node.js Runtime Into Malware Delivery Tool in Targeted Attacks

Symantec reports multiple threat actors, including KongTuke, abusing the trusted signed Node.js runtime and blockchain C2 (EtherHiding) to deliver backdoors in targeted attacks.

Symantec's Threat Hunter Team (Broadcom) reports that since February 2026 attackers have used the legitimate signed node.exe binary and interpreted scripts to deliver implants while evading signature-based detection, hitting government departments, technology companies, and hotels. One intrusion at an Asian technology firm (March 23–July 25, 2026) used ClickFix social engineering, the official Node.js installer, and EtherHiding to fetch commands via the Ethereum blockchain after AdaptixC2 and Cobalt Strike attempts were blocked. Related chains involve KongTuke (Woodgnat) using ModeloRAT, Mistic, NexShield, and GateKeeper, plus C2Looper, AsukaStealer, and EtherRAT; GuidePoint Security separately linked a fake-CAPTCHA ClickFix campaign to at least 31 compromised organizations using the Polygon blockchain as a dynamic C2 address book.
