Neowin.net have posted an interesting article about a cable modem hacking trick or a DOCSIS vulnerability in cable networks. Here's what they're saying:
When his cable modem service seemed to slow almost to a crawl last spring, Matthew Hallacy did like most people and complained to technical support at his Internet service provider, AT&T Broadband.
But after the sluggish performance persisted for weeks, Hallacy, a Minnesota-based software engineer and networking expert, decided to take matters into his own hands: he hacked his cable modem.
It wasn't long before Hallacy, 21, devised a trick for modifying an obscure configuration file used by the service to control the settings in his 3Com cable modem.
A few tweaks later, Hallacy's $50-per-month service, which had been downloading data at a poky 75 kilobits per second (Kbps), was sweetly humming along at much brisker speeds in both directions. According to Hallacy, he hacked the modem just to prove that AT&T's network management, and not his modem, was the performance bottleneck, and he immediately changed the settings back.
