Malicious code in proxycer (PyPI)
Details
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (2286dac5be0a9e8cc2e7b1ff92253d4b09beb0c43d5e795b9b9ea1391e6f8764) The package's top-level __init__.py imports starts.py, which is a single-line loader that reverses a ~100KB string literal, base64-decodes it, marshal.loads the result into a code object, and exec()s it. All actual functionality is concealed behind reversal + base64 + marshal bytecode obfuscation, with an empty README and empty PKG-INFO description. The obfuscated code object runs automatically on `import proxycer`, so any behavior it contains (credential access, outbound network, filesystem writes, persistence) executes on the installer's host without source visibility. ## Source: kam193 (c7f54d8a442ae6b7c359629af5db210aafade4776e03f44895e67923bd464e29) The provided functionality hides code that exfiltrates files to a remote location. --- Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
