Details

-= Per source details. Do not edit below this line.=-

Source: google-open-source-security (56df7571e75ad7e85850f9a34bb482f19466af4481db56951ffba42475a4238d)

This package is malicious and typosquating the legitimate pyspellchecker library. This package will deploy a remote-access trojan that allows the attacker full control of the victim's host.

Source: kam193 (a08f9f271e62949f07029e8c2dc7c8904e7272750fe9789442d4549be52c639f)

Packages contain hidden code that is effectively run during importing or using the library, and downloads second stage code. Then, a process running in background periodically connects to a remote host and waits for next code to execute


Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: 2025-11-spellcheckers

Reasons (based on the campaign):

  • obfuscation

  • Downloads and executes a remote malicious script.

  • The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.
