In December 2011, Ehsanullah disputed that the Pakistani Taliban was negotiating a cease-fire with the Pakistani government. He asserted that the individuals negotiating that cease-fire were doing so without the authorization of the Taliban's leadership. He was sacked on June 25, 2013.
On June 23, 2013, Ehsan claimed responsibility for the killing of nine foreign tourists and their guide in Gilgit-Balitistan. 
On October 9, 2012, Ehsan claimed responsibility for the Taliban shooting in the head of a 15-year old Pakistani activist, Malala Yousafzai, a girl who was famous for highlighting Taliban atrocities. He said that the teenager's work had been an "obscenity" that needed to be stopped: "This was a new chapter of obscenity, and we have to finish this chapter."  On October 15th, Pakistani interior minister, Rehman Malik, offered a $1 million bounty for Ehsan.
On November 22, 2012, Ehsan claimed Taliban responsibility for suicide bombings carried out the day before against Shiites in Rawalpindi and Karachi. As justification for the attacks, he stated that "the Shiite community is engaged in defiling the Prophet." He also asserted that his group's activities would continue "irrespective of security measures taken by Rehman Malik." 
On December 15, 2012, Ehsan confirmed Taliban involvement in a rocket attack on Bacha Khan International Airport that killed 4 people and wounded 35. He noted that the attack's intended target was actually an adjacent airbase, and claimed that the Taliban "have planned more attacks on Pakistani forces and its installation as it works to please the USA".
