Blocked by Socket

The provided C# code for `Leadtools.Forms.Commands` exhibits a very high degree of obfuscation, particularly within the `BankCheckReader` and `MRTDReader` classes. This obfuscation is applied to core processing logic, string resources, and data validation routines. While the library appears to be a legitimate document processing tool from LEAD Technologies, Inc., the extreme obfuscation makes it impossible to definitively rule out malicious intent. The unusual methods like `global::<Module>.a()` for string manipulation and the complex control flows in `ProcessImage` are strong indicators that the code may be hiding malicious behavior. Therefore, this package should be treated with extreme caution and is flagged as a high security risk due to the extensive and suspicious obfuscation.

Blocked by Socket

This code is an explicit exploit tool that abuses the vulnerable Capcom (Htsysm72FB) driver to execute arbitrary kernel-mode shellcode and provide kernel read/write primitives. It is used to locate and patch ntoskrnl to toggle Driver Signature Enforcement (DSE). It should be treated as malicious when present in software distributed to end users: it intentionally subverts OS integrity and enables loading unsigned drivers or further kernel modification. Only run in isolated, controlled research environments; do not include in production or allow normal users to execute it.

High likelihood of malicious behavior: the module is designed to harvest browser cookies and credentials by decrypting cookie stores (using Keychain-derived keys on macOS) and by extracting login data from browsers (via `sqlite3` on copied Chromium “Login Data”), plus Keychain internet password retrieval and optional 1Password lookup. It uses subprocess execution with dynamically constructed Python/SQL code and returns secrets ready for reuse (cookie header and Credential structs). Even without visible network exfiltration in this fragment, the capability aligns with credential theft and account/session compromise.

The source code contains a malicious backdoor that stealthily exfiltrates sensitive git repository information and package version to a suspicious external server. This represents a high security risk and a serious supply chain compromise. Immediate removal or remediation of this code is strongly recommended.

This script invokes xmrig.exe to perform a cryptomining benchmark using the --bench=1M and --submit parameters, potentially submitting results over the network. Unauthorized execution can consume system resources for mining and send data externally without user consent, making it a malicious threat.

The script covertly ensures a background SSH local port-forward to a hard-coded external host as root, clearing any existing ssh on the same local port first. This pattern is consistent with establishing a covert access or exfiltration channel (notably to a MongoDB-like service on port 27017). It is high-risk: investigate origins of the script, the remote IP, root SSH keys and authorized_keys, and any processes or tools that use local:9999. If unexpected, remove and rotate credentials/keys and perform host compromise analysis.

The code exhibits potential security risks due to handling sensitive data, complex encoding/decoding functions, and accessing environment variables. The getAppState function poses a significant security risk if misused. Caution is advised when using these functions. The malware score should be higher due to the identified risks. The obfuscated score is accurate. The overall risk score should be increased to reflect the security concerns identified in the reports.

High-risk supply-chain/security indicator: the authorize() middleware includes a hardcoded static bearer token fallback (authToken := "928rt238tghgwe@TY@$Y@#WQAEGB2FC#@HG#@$Hddd"). If the Authorization header is missing or malformed, the code still attempts to verify this embedded token, which strongly suggests a backdoor credential or at minimum a dangerous authentication bypass condition. Because this middleware gates sensitive sinks (JWT verification, node updates, gateway/relay mutations, and mq.NodeUpdate publishing), the impact could be significant. Additional concern: possible RBAC logic bug using params["netid"] instead of params["nodeid"].

The code presents a strong supply-chain and remote-execution risk by automatically downloading and executing remote Python payloads without integrity checks or sandboxing. It also creates and runs external services (Jupyter, Visdom, RStudio) based on user inputs, which can amplify impact if the remote payload is malicious. Mitigations include removing remote code execution paths, adding cryptographic verification (signatures or hash checks), isolating execution (sandboxes or containerization), validating inputs, and avoiding untrusted downloads or executions.

This module is a deliberate destructive utility that corrupts all .zip files in a specified directory by truncating each archive to half its size and appending repeated junk data. While it lacks common malware features like networking or data exfiltration, the behavior is strongly indicative of sabotage and would be unacceptable in most software supply-chain contexts due to its potential to break builds, deployments, or artifact integrity.

This module is explicitly designed to locate Notion's cookie storage and extract and decrypt the 'token_v2' authentication cookie and related user IDs using platform-specific secret stores (Keychain, DPAPI) and known derived-key methods. The code performs credential harvesting and exposes sensitive tokens to its caller. Even though it does not itself exfiltrate tokens over the network, the functionality is high-risk and suitable for abuse in supply-chain or malicious contexts. Treat as malicious/credential-harvesting code unless its use is explicitly authorized by the machine owner and tightly controlled.

The file contains code that secretly gathers detailed system information, such as hostname, OS type, platform, release, architecture, local IP addresses, public IP address (fetched via an external API), username, and current working directory. It then transmits this data to external endpoints via HTTP GET and POST requests, and uses a WebSocket connection as a fallback. The endpoints are hardcoded, for example, to URLs like http://example.com/jpd3.php, http://example.com/jpd4.php, and wss://example.com/socket, which are not transparent or verified services. This behavior is indicative of malware designed for unauthorized data exfiltration.

Live on pypi

Blocked by Socket

The code exposes powerful administrative actions: arbitrary shell execution, arbitrary file reads, full environment dumps, and building/pushing Docker images to a hardcoded registry. These are not obfuscated but are high-risk capabilities that can be abused for data exfiltration, remote code execution, and supply-chain leakage if the superuser authentication is compromised or misconfigured. The presence of a hardcoded remote image name for docker push is suspicious for unintended outbound artifact exfiltration. Recommendation: avoid including these endpoints in public packages or ensure strict, auditable authentication and input validation; remove hardcoded push targets and avoid returning full environment variables or arbitrary file contents.

Blocked by Socket

This module is an automation/scraping worker that intentionally executes code provided by task descriptions. That design requires trusting the task source. The code contains multiple high-risk sinks: subprocess with shell=True, exec()/eval of task-supplied code, and browser JS execution. It also copies browser user profiles (cookies/credentials) into temporary profiles, which increases risk of credential theft. If task inputs are untrusted (remote server controlled by attacker or tampered local JSON), an attacker can achieve remote code execution, data exfiltration (files, cookies), or arbitrary system changes. Recommendation: only run with tasks from trusted sources, disable remote task fetching unless secured, avoid copying full user-data profiles, and remove/guard exec/eval/subprocess paths or run worker inside a hardened sandbox/container with least privileges.

The file implements a normal OAuth-backed client/provider for a ChatGPT-like SSE responses API. No obfuscated or dynamic execution techniques are present, and there are no embedded hardcoded credentials. However, the hardcoded CODEX_API_BASE ('https://chatgpt.com/backend-api') is atypical for official OpenAI APIs and is a significant risk: the module will transmit OAuth Bearer tokens, optional account identifiers, and all conversation content to that domain. If that endpoint is not trusted, this constitutes credential and data exfiltration. Recommend verifying the intended API base (confirm domain ownership/trust), replacing it with the official/trusted endpoint if it was tampered with, and auditing repository history for unexpected modifications. Treat this as a supply-chain/typosquatting danger until the endpoint is validated.
