Crypto tokens are versatile digital assets used within the blockchain ecosystem. Crypto tokens are used to represent a wide range of values, rights, or utilities. They play a crucial role in decentralized finance (DeFi), governance, and other blockchain-based applications. Most crypto tokens are built on existing blockchains using smart contracts. A smart contract is a self-executing contract with the terms of the agreement directly written as lines of code. These contracts automatically execute and enforce themselves when predetermined conditions are met, without the need for intermediaries. For this reason, attackers often aim to steal crypto tokens from the machines they infect. Once stolen, crypto tokens are difficult to trace or recover due to the decentralized and pseudonymous nature of blockchain technology. The irreversibility of blockchain transactions means that once the tokens are transferred to the another crypto wallet, they are effectively gone, making them an attractive target for financially motivated actors. While presence of regex code that detects crypto tokens does not imply malicious intent, all of its uses in a software package should be documented and approved. Only select applications should consider working with crypto tokens.

Problem

Uniform Resource Locators (URLs) are structured addresses that point to locations and assets on the internet. URLs allow software developers to build complex applications that exchange data with servers that can be hosted in multiple geographical regions. URLs can commonly be found embedded in documentation, configuration files, source code and compiled binaries. A port number is associated with a network address of a host, such as an IP address, and the type of network protocol used for communication. Within URLs, the ports are optional. Ports can be specified in a URL immediately following the domain name. Each network protocol, or schema, has a set of standard ports on which the service operates. This issue is raised when a mismatch between a network protocol and its expected port number is detected. While the presence of non-standard ports does not imply malicious intent, all of their uses in a software package should be documented and approved.
