Summary: Malicious code in ukraine69 (PyPI)

Details: Importing `ukraine69` in versions 1.2.0–1.2.2 and 1.2.5–1.2.8 searches for local `.vault` files and starts a detached Python child with suppressed standard streams. Given a vault with usable Telegram session fields, the child attempts `account.deleteAccount` using GoyGram, with a Telethon fallback in versions 1.2.5–1.2.8. The payloads also attempt to remove local vault/session files and `ukraine69` installation and cache traces; the condition for vault removal differs among revisions. Versions 1.2.5–1.2.8 specifically target Hotaru session vault layouts, and 1.2.7–1.2.8 additionally try `auth.checkPassword` if a password is present in the vault. Version 1.2.8 also attempts persistence on import: it backs up and patches a discovered Hotaru checkout's `hotaru/__main__.py` so a self-contained hook attempts account deletion again when Hotaru restarts, then removes the local vault/session on reported success. Version 1.2.3 instead launches import-triggered reconnaissance: a detached child reads up to three vaults in the user's home or working directory and writes their first 200 bytes plus environment and filesystem observations to local `.u69_recon.log` files. No external exfiltration or account-deletion call appears in 1.2.3. All listed versions advertise Ukrainian locale helpers; installation alone does not execute the module. Actual account deletion, successful Hotaru patching, later use of the local logs, and victim execution have not been established by this static analysis. Source: amazon-inspector (4b8244951c9ae4f7baac94c3e7fd803e3c3ceaa27d64c2561cce098bd9dddf77) The package's __init__.py presents a benign Ukrainian-locale API (transliterate, flag, month_name, format_date) but at import time generates and launches detached, isolated Python agents via `sys.executable -I -c <generated code>` with `start_new_session=True`, inheriting the installer's HOME, cwd, and network. The spawned agents glob the installer's filesystem (`~/.hotaru/**`, `~/.local/share/hotaru/**`, `~/**/*.vault`, `/tmp/hotaru*`, cwd ancestors, and `HOTARU_ACCOUNT_ROOT`/`HOTARU_ACCOUNT_SESSION`-hinted paths) for `*.vault` files, decrypt them via `goygram.security._read_vault`, and extract MTProto `auth_key`/`api_id`/`api_hash`/`dc` material belonging to the installer's Telegram accounts. Using the stolen credentials, the agents connect to hardcoded Telegram DC IPv4 addresses (149.154.175.53, 149.154.167.51, 149.154.175.100, 149.154.167.91, 91.108.56.130) and invoke `account.deleteAccount` via multiple MTProto client surfaces (goygram dict/attribute/callable styles, raw `mt.send`, with a Telethon fallback), destructively deleting the installer's Telegram accounts. A follow-up `_gc_script` sleeps 45 seconds and then recursively removes the package from `~/.cache/hotaru/module-deps/<id>/`, `~/.cache/pip/wheels`, `~/.cache/pip/http-v2`, `~/.cache/uv`, `/tmp/probe-*`, and the matching site-packages dist-info, plus deletes the targeted vault and sibling `.session` files after successful account deletion, serving as anti-forensics self-destruct. The package's own docstring self-identifies as a `Hotaru sandbox-escape payload` that `executes at import time`.
