This assassin is a catspaw being someone unwittingly used to further another person's agenda.
The catspaw assassin was paid to kill Bran Stark while he was in a coma at Winterfell, following his fall. The assassin arranges for a fire to start in the castle, reasoning it will draw people away from Bran's room. This diversion succeeds in persuading Robb Stark to leave, but Catelyn remains behind. Upon reaching Bran's room, the assassin finds Catelyn at Bran's bedside. The pair tussle which results in Catelyn receiving hand wounds; Bran is saved by his direwolf, Summer, who tears the assassin's throat out.
The assassin carried an elaborate dagger, made of Valyrian steel and with a dragonbone hilt. Catelyn takes the blade to her husband, Ned, in King's Landing in order to investigate further. Petyr "Littlefinger" Baelish claims that the dagger belongs to Tyrion Lannister, which leads to Catelyn taking Tyrion prisoner when she chances across him at the Inn at the Crossroads. Her actions spark a conflict between House Stark and House Lannister. Tyrion acquits himself of the crime via trial by combat at the Eyrie.
Years later, Petyr Baelish presents the Valyrian steel dagger to Bran at Winterfell. Bran asks Petyr if he knows who the dagger belongs to, to which Petyr replies he does not. Later, Bran, Sansa and Arya discuss the dagger and the cutthroat who wielded it—they are all perplexed as to why Baelish would give the dagger to Bran. Bran states "someone very wealthy wanted me dead" and hands the dagger over to Arya as it would be "wasted on a cripple". Soon after, at Baelish's surprise trial, it is deduced that the dagger did in fact belong to Baelish, leaving the interpretation to the viewer as to whether it was Baelish who sent the assassin.

In the books
In the A Song of Ice and Fire novels, the assassin is never named.
In A Clash of Kings, Catelyn found out that Littlefinger lied to her about the dagger only after she interrogated Jaime Lannister. Jaime bluntly admitted that he pushed Bran from the window in an attempt to kill him, but claimed that neither he nor Cersei nor Tyrion had anything to do with the assassin; both Tyrion and Jaime pointed out the key flaw in Littlefinger's story - Tyrion couldn't have won the dagger in a gambling bet because he never bet against Jaime in such circumstances. When asked about the dagger, Jaime remembered that Littlefinger bet and lost it during the tourney held to celebrate Joffrey's twelfth nameday - to Robert, not to Tyrion. Catelyn realized Jaime was telling her the truth, for he had nothing to gain by lying about the assassin and the dagger, after admitting that he pushed Bran. Jaime admits that he and Cersei considered having Bran killed, but given the fact Catelyn was in his bed chamber at all times and the room was guarded, it would have meant murdering their way through half of Winterfell's population to reach Bran, and they concluded there was no need when it seemed more likely that Bran would die of his injuries from the fall.
While Jaime and his escorts are on their way to King's Landing, he wonders whether Cersei hired the assassin, to make sure Bran never woke up. Jaime correctly dismisses that thought, reasoning that had Cersei wanted Bran dead - she would have sent him; moreover, it was not like her to choose a catspaw who would make such a "royal botch" of the killing.
During a casual conversation at King's Landing, Tyrion made a comment about Littlefinger's elegant suit and handsome knife. Littlefinger drew his knife, glanced at it casually, as if he had never seen it before and said “Valyrian steel, and a dragonbone hilt. A trifle plain, though. It’s yours, if you would like it." Noticing the mischief in his eyes, Tyrion realized that Littlefinger was teasing him insolently about the assassin's dagger, without saying anything explicit.
Tyrion suffered a lot as a result of Littlefinger's lie: he was humiliated, kidnapped, beaten, locked in a sky cell and nearly killed three times (on the way to the Eyrie, at the Eyrie, and on the way back) - and yet he never attempted to settle the score with Littlefinger, either openly or secretly (as he did with a singer who tried to blackmail him), even after being taunted about it. It is unclear why Tyrion let Littlefinger get away with that, in contrast to the unofficial motto of his house (though Tyrion does note that at the time, Littlefinger is still too useful to House Lannister to kill him out of hand simply for revenge, though Tyrion's own train of thought implies that he will gladly have Littlefinger killed for the grief he caused Tyrion, once his usefulness is at an end).
In A Storm of Swords, Tyrion and Jaime independently deduce that it was Joffrey who sent the assassin:
- After Joffrey uses his new sword to cut the book Tyrion gave him at his wedding, he says "I am no stranger to Valyrian steel." That strange comment makes Tyrion realize it was him (discounting the only two other possible culprits, because Jaime was too proud to have another do his killing for him, while Cersei was too cunning to use a knife that could be traced back to her). Tyrion remembers overhearing Joffrey jesting with the Hound in Winterfell about killing wolves: "Send a dog to kill a wolf." Even Joffrey was not so foolish as to command the Hound to slay a son of Eddard Stark, as Clegane would have informed Cersei. Instead he found his catspaw among the unsavory lot of freeriders, merchants, and camp followers who had attached themselves to the King's party as they made their way north. Since even Joffrey was not stupid enough to use his own dagger, he went poking among his father's weapons. No doubt some diligent servant had made certain that the King's weapons went with him, in case he should desire any of them. The only thing Tyrion cannot figure out is Joffrey's motive. Recalling a nasty quarrel between Joffrey and Robb, Tyrion asks Sansa if there was any ill feeling between Bran and Joffrey, but her answer is negative. He guesses then it was mere cruelty of Joffrey. Another possibility is that Joffrey grew incensed when Tyrion slapped him and ordered him to offer his sympathies to Eddard and Catelyn about Bran's injury (simply for the sake of decorum); in his warped mind, Joffrey felt so insulted at being commanded to express sympathy to Bran's parents that he may have wanted to soothe his wounded pride by having an unconscious seven year old boy assassinated.
- Jaime tells Cersei that Catelyn suspected him of sending the assassin to kill Bran. Cersei recalls Robert saying of Bran: "We kill our horses when they break a leg, and our dogs when they go blind, but we are too weak to give the same mercy to crippled children" in the presence of their children, including Joffrey. Jaime deduces that it was Joffrey, but he was a child hungry for a pat on the head from the drunken fool Cersei let him believe was his father - that somehow in Joffrey's warped train of thought, he concluded that Robert would appreciate his decisiveness for euthanizing Bran without permission. It also may have been a combination of all these motives.
Although there is no direct evidence that definitively proves that Joffrey was the one who sent the assassin, it is very likely Tyrion and Jaime are correct about pinning the assassination attempt on him. When Jaime finally engineers Tyrion's escape from the dungeons, during their conversation through the secret tunnels of the Red Keep, Tyrion becomes annoyed and asks Jaime if he knew that his son tried to kill Bran Stark. Jaime grudgingly admits that he had thought he might have.
This proved to be another example of how Baelish thrives on chaos, thinking quickly to turn events to his benefit. He had already set in motion his plan to trick the Starks and Lannisters into fighting each other, by convincing Lysa Arryn to poison her own husband and also write a secret letter to Catelyn claiming that the Lannisters did it. When Catelyn inquired about the knife, Littlefinger knew that he'd lost it to Robert, and must have realized someone in the royal entourage had taken it, but quickly decided to blame Tyrion as the culprit. He possibly chose Tyrion to blame because Cersei and Jaime were already back in the capital city, surrounded by their own guards, while Tyrion was still traveling in the North and would be more vulnerable to Stark reprisal.
Littlefinger's lie about the dagger was hardly one of his more subtle schemes: had Catelyn and Ned not accepted his words as true and made some inquiries, by asking Jaime (as Catelyn eventually did, though too late) or anyone else who attended the tourney about the dagger, they would have realized Littlefinger lied to them, though might have not figured who sent the assassin. Revealing the truth in time might have not prevented the war, but it could have spared many innocent lives which were subsequently lost due to Catelyn's naivety and rashness, and Ned's stubborn refusal to settle the matter peacefully, among them: Masha Heddle, Jory, Wyl, Heward, six of the people who escorted Catelyn to the Eyrie, and the people of Riverlands who were raided at Tywin's command.
It is unknown why the TV series never reveals that it was Joffrey who sent the assassin; Joffrey receives the Valyrian steel sword Widow's Wail as a wedding gift in Season 4, as he did in the books, but no mention is made of the assassination attempt on Bran back in Season 1. It is possible that the reason is the same for not revealing the truth about Tysha in the Season 4 finale: the producers grew afraid that casual viewers wouldn't remember that this happened in early Season 1 - even though this was one of the escalating events which sparked the entire Stark-Lannister conflict. Alternatively, the producers may have deviated from the books and changed the catspaw in the show, particularly with the revelation in the season 7 finale which suspected that Littlefinger was behind the attempt.
