Definition ∞ Npm typosquatting is a cybersecurity attack where malicious software packages are published with names similar to popular legitimate packages on the npm registry. Attackers exploit common typing errors or misspellings developers might make when installing software dependencies, leading them to inadvertently download and execute compromised code. These deceptive packages often contain malware designed to steal credentials, inject backdoors, or compromise development environments. The technique preys on human error and the vast ecosystem of open-source software dependencies.
Context ∞ Npm typosquatting remains a persistent threat in the software development and blockchain security landscape, given the extensive reliance on open-source libraries. A key discussion involves the responsibility of package registries and developers in preventing and detecting such attacks. Future developments include enhanced automated scanning tools, improved package verification processes, and stricter naming conventions to identify and remove malicious packages more effectively. Vigilance in dependency management is crucial to mitigate this vector of attack.
