Miles felt his stomach clench. The company’s contract had lapsed two months ago—a budget-cutting casualty. He had a read-only J-Web login, but that didn’t grant access to the secure firmware repository. juniper firmware downloads
Miles held his breath. He downloaded the 2.3 MB file. He ran the file command, checked the SHA-256 against a known good hash from a colleague’s verified screenshot, and cross-referenced the signature.
