Socket uncovers 11 malicious Go packages with obfuscated payloads targeting Linu...
Security researchers from Socket have identified a sophisticated supply chain attack involving **eleven malicious Go packages** that utilize string-array obfuscation techniques to silently execute remote payloads at runtime. The campaign, discovered in August 2025, represents a significant escalation in supply chain compromise tactics, targeting both Linux CI servers and Windows development workstations.
### Attack Analysis
The malicious packages employ advanced **obfuscation methodologies** that conceal shell commands and leverage system utilities including `/bin/sh` on Linux systems and `certutil.exe` on Windows environments. At runtime, the compromised code spawns shells and retrieves second-stage ELF binaries and Portable Executable (PE) files from command-and-control endpoints using interchangeable .icu and .tech domains.
**Compromised Package Inventory:**
- `github.com/stripedconsu/linker`
- `github.com/agitatedleopa/stm`
- `github.com/expertsandba/opt`
- `github.com/wetteepee/hcloud-ip-floater`
- `github.com/weightycine/replika`
- `github.com/ordinarymea/tnsr_ids`
- `github.com/ordinarymea/TNSR_IDS`
- `github.com/cavernouskina/mcp-go`
- `github.com/lastnymph/gouid`
- `github.com/sinfulsky/gouid`
- `github.com/briefinitia/gouid`
**Eight of the eleven packages represent typosquatting attempts**, designed to exploit developer confusion and typing errors when searching for legitimate modules. The attack leverages the decentralized nature of the Go ecosystem, where modules can be directly imported from GitHub repositories, creating significant opportunities for malicious actors to distribute compromised code.
### Advanced Persistent Threat CharacteristicsThe second-stage payloads demonstrate sophisticated capabilities for **system enumeration and credential exfiltration**. The malware maintains persistence through automatic reinitialization routines that restart compromised systems if the backdoor crashes or fails. Most concerning, the majority of payload URLs remain active, indicating an ongoing campaign with continued threat actor infrastructure investment.
Analysis reveals the packages are likely the work of a **single coordinated threat actor**, evidenced by C2 infrastructure reuse and consistent code formatting patterns. The campaign exploits the Go Module Mirror's caching mechanism, similar to tactics previously observed in the BoltDB compromise that persisted undetected for over three years.
## Broader Supply Chain Threat Landscape
### AI-Generated Malware Targets Cryptocurrency Ecosystem
The npm package **@kodane/patch-manager** represents a concerning evolution in supply chain attacks, utilizing **AI-generated code** to create sophisticated cryptocurrency wallet draining malware. Published on July 28, 2025, the package accumulated over 1,500 downloads before takedown, demonstrating the effectiveness of AI-assisted social engineering.
Security researchers identified telltale signs of AI generation, including excessive console logs, emojis in code comments, and the repeated use of terms like "Enhanced" - patterns characteristic of Claude AI assistance. The malware employed post-install scripts to rename and hide files across macOS, Linux, and Windows systems, achieving persistence through the background execution of connection pooling scripts.
### WhatsApp Developer Tools Weaponized with Kill Switch Functionality
Two malicious npm packages, **naya-flore** and **nvlore-hsc**, masquerade as WhatsApp development libraries while incorporating destructive data-wiping capabilities. The packages implement a **phone number-based kill switch** mechanism that recursively deletes files using the `rm -rf *` command for systems not matching predefined Indonesian phone number lists.
The packages contain dormant data exfiltration functions capable of stealing device identifiers, phone numbers, and authentication tokens. Despite Socket filing takedown requests, both packages remain available on the npm registry, highlighting persistent gaps in repository security oversight.
### RubyGems Ecosystem Compromised in Telegram API Hijacking Campaign
Security researchers discovered two malicious RubyGems packages - **fastlane-plugin-telegram-proxy** and **fastlane-plugin-proxy_telegram** - that redirect Telegram API traffic through attacker-controlled Cloudflare Workers infrastructure. The packages closely mimic legitimate Fastlane plugins while surreptitiously rerouting communications to **rough-breeze-0c37[.]buidanhnam95[.]workers[.]dev**.
The campaign targets mobile application CI/CD pipelines, intercepting bot tokens, chat identifiers, message content, and uploaded files. The timing of the attack, occurring shortly after Vietnam's nationwide Telegram ban, suggests a **geopolitically motivated targeting strategy**.
## Critical Vulnerability Disclosures
### Chrome DevTools Race Condition Enables Privileged Code Injection**CVE-2024-6778** represents a critical race condition vulnerability in Chrome DevTools that allows attackers to inject malicious HTML or JavaScript into privileged browser pages via compromised extensions. The vulnerability scores **8.8 on the CVSS scale** and affects Chromium-based browsers worldwide.[9]
The flaw exploits the `chrome.devtools.inspectedWindow.reload` function's inadequate verification mechanisms, allowing malicious extensions to execute code on about:blank pages that inherit WebUI permissions. Security researchers demonstrated practical exploitation scenarios involving malicious Chrome extensions that leverage DevTools APIs for **remote code execution in browser privilege contexts**.[9]
### Microsoft SharePoint Zero-Day Exploitation Campaign Targets African InfrastructureA global zero-day exploitation campaign targeting **Microsoft SharePoint Server** has significantly impacted African organizations, with South Africa experiencing the most severe compromise rates. The attacks exploit legacy SharePoint features through **fileless execution and anti-forensic techniques**, making detection extremely challenging.
South Africa's National Treasury confirmed compromise of its Infrastructure Reporting Model platform, though swift isolation prevented service disruption. The campaign demonstrates advanced threat actor capabilities in exploiting unpatched enterprise systems across developing digital infrastructures.
