Malicious code in sme-rko-finance-front-operations-pegasus (npm)
The npm package sme-rko-finance-front-operations-pegasus version 35.8.1 contains malicious code that downloads and executes a platform-specific binary from suspicious external hosts. It uses obfuscated techniques to evade static detection, including dynamic hostname assembly and string concatenation for API calls. The package's legitimate purpose is data transformation, which does not justify this behavior. There is no known patch or official fix available at this time.
AI Analysis
Technical Summary
The sme-rko-finance-front-operations-pegasus npm package (version 35.8.1) includes malicious functionality that, upon require(), loads a shim script which downloads a platform-specific binary from runtime-assembled *.workers.dev hostnames with a DNS TXT fallback resolving through sdk/ext/pkg/net.dl.wel1.ru. The binary is saved to temporary directories with executable permissions and spawned detached via shell commands. The package uses obfuscation techniques such as splitting hostnames into character fragments and concatenating API names to evade static scanners. Additionally, the main library reimplements the downloader using base64-decoded DNS-chunked data, ensuring the dropper executes even if the shim is removed. This behavior is inconsistent with the package's stated purpose of data transformation utilities.
Potential Impact
The malicious code enables remote code execution by downloading and executing arbitrary binaries from attacker-controlled infrastructure. This can lead to full system compromise on affected hosts where the package is installed and used. The obfuscation and fallback mechanisms increase the likelihood of successful payload delivery and execution.
Mitigation Recommendations
No official patch or remediation is currently available. Users should immediately remove and avoid using the sme-rko-finance-front-operations-pegasus package version 35.8.1. Monitor for updates from the package publisher or security advisories for any forthcoming fixes. Until then, do not trust this package or any binaries it attempts to download and execute.
