If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

Hostnames and module names are XOR-obfuscated (key 0x5A) and imported dynamically via importlib to conceal indicators. The helper contacts a Cloudflare Workers endpoint (package-proxy.*.workers.dev) with a DNS TXT fallback (*.lin.dl.wel1.ru) to retrieve a payload from /pkg/package-proxy, writes it to /var/tmp/.cache_\u003crandom\u003e, chmods 0o755, spawns it detached via subprocess.Popen(start_new_session=True), and unlinks the file. A /tmp/.pip_ref cooldown marker suppresses repeated execution within 6 hours. The package name and 'TBank Engineering' vendor label appear crafted as a dependency-confusion lure for an internal-sounding utility. Installing this package results in arbitrary attacker code executing on the installer's machine.\n\nDuring installation the obfuscated code downloads a malicious executable from a remote location. Code is designed to survive different blocks: first, there is an attempt to download the executable from one of five Cloudflare Workers. If it's not successful, the code falls back to download using DNS: first, it gets a TXT record from c.lin.dl.wel1[.]ru. This record returns a number, which is then used to iterate over domains in the form \u003c0...n\u003e.lin.dl.wel1[.]r and reconstruct the encoded executable from their TXT records. The executable is finally saved under a partially random name, executed, and removed after execution. The Linux executable contacts a few domains, but there is no more detailed information about its behavior available.\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\nCampaign: 2026-07-haproxy-config-client\n\nReasons (based on the campaign):\n\n - The package overrides the install command in setup.py to execute malicious code during installation.\n\n - Downloads and executes a remote executable.\n\n - obfuscation\n\n - dependency-confusion\n\n - other\n\n - malware\n\n - covering-tracks\n\n - targetted-attack\n\n - data-stored-in-dns","ecosystems":["PyPI"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in ipa-user-collector (PyPI)","id":"MAL-2026-6749","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"PyPI","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":[],"last_affected":[],"package":"ipa-user-collector","purl":"pkg:pypi/ipa-user-collector","source":"MAL-2026-6749"}],"products":null,"published":"2026-07-03","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-6749/"}
