BSNL with its stupid scheme of having the first 3 letters of the username followed by 123. With my delphi skills and couple of hours I could harvest around 20 working passwords from just 4 or 5 google pages. Whose was the stupid idea I don’t know, but if u haven’t changed it yet, don’t delay any more. Most have not changed it as bsnl has configured ppoe on the modem and dialout is automatic. Most people have no clue on configuring the modem via telnet or browser.
