--- _-= Per source details. Do not edit below this line.=-_ ## Source: kam193 (40fa77c47c3649fce85f601f8aa10bf13674e5db4a2d35f125cb48b77d65f99d) The package clones a legitimate webdavclient3 library and modifies it to be an installer utility. During installation, the package exfiltrates the current working directory to a remote WebDAV server or Telegram Bot. Additionally, the package targets cryptocurrency operations in another suspicious project, https://github.com/fewcatltd/zkSync/ The install_modules() method injects code into two files, which are characteristic for this repository, and causes exfiltrating configuration files during cryptocurrency exchange operations. --- Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
