Why would a terrorist claim credit for a failed (sometimes badly) attack?
The botched Times Square plot; Tehrik-i-Taliban Pakistan (the Pakistani Taliban”, TTP) claims responsibility.

Tactical failures might be seen to have some strategic success when the target or its protectors react in ways that are costly and ultimately futile. In a “bleeding” strategy, they might, in essence, be bleeding themselves.
Al Qaeda had historically tended not to to claim responsibility for even successful attacks (most notably the East Africa embassy bombings). And certainly never for failed attacks or foiled plots (Richard Reid, Jose Padilla, the 2006 transatlantic air plot–which was, incidentally, the seminal event that led to us checking constrained volumes of shampoo and mouthwash in Ziploc bags); all these have been linked to AQ.

Some insight might be gleaned from Usama bin Laden (UBL) himself, in claiming that our response to minor financial and physical efforts on the part of terrorists may cost millions, even billions. A particularly literal reading of asymmetric warfare:
…for example, al-Qaida spent $500 000 on the event, while America, in the incident and its aftermath, lost – according to the lowest estimate – more than 500 billion dollars. Meaning that every dollar of al-Qaida defeated a million dollars by the permission of Allah, besides the loss of a huge number of jobs.
As for the size of the economic deficit, it has reached record astronomical numbers estimated to total more than a trillion dollars.
And possibly, a lesson on measuring the means and goals of our reactions:
All that we have to do is to send two Mujahideen to the furthest point East to raise a piece of cloth on which is written al-Qaida, in order to make the generals race there to cause America to suffer human, economic, and political losses without their achieving for it anything of note other than some benefits for their private companies.
Ultimately, the Times Square attempt, the Christmas Day bomb attempt, etc., were foiled not by law enforcement or military measures, but by ordinary people–street vendors, even. UBL says, “Your security is in your own hands”; I suspect this isn’t what he means, but I’m really fond of Stephen Flynn’s formulation of taking one’s security into their own hands:
There were no federal air marshals aboard the aircraft. The North American Aerospace Defense Command, or NORAD, could not intercept it; it did not even know that the plane had been hijacked. Yet United 93 was stopped 140 miles from its likely destination—the U.S. Capitol or the White House—because of the actions of the passengers who stormed the cockpit… Americans should celebrate — and ponder — the reality that the legislative and executive centers of the U.S. federal government, whose constitutional duty is to “provide for the common defense,” were themselves defended that day by one thing alone: an alert and heroic citizenry.
