Additionally, src/index.js's exported init()/check()/wrap() API falls back to the same hardcoded DSN when neither options.dsn nor process.env.SENTRY_DSN is set and enables sendDefaultPii: true, so consumers following the README route their application's exception data (including PII such as IP addresses) to the author's Sentry project by default.\n\n## Source: ghsa-malware (1012357081d7f64d29bd6ddbe25552eabad3448e18c5a99a931cc1b20e31d072)\nAny computer that has this package installed or running should be considered fully compromised.
