It is known that he was inspired by the preaching of Abu Bakar Bashir. Some reports say he studied Islam at Al-Mukmin Islamic school in Ngruki district, Surakarta, Central Java. According to an interview with Andi Baso Tahir, an old friend of Santoso in Tokorondo village, in 2006 Santoso was arrested for robbing a boxcar in a coastal town of Poso. He was jailed for a year. According to the friend, after he left prison, Santoso stopped militancy for a period and "became a peddler, selling cleavers, cooking utensils and clothes".

Sudirman were found in a shallow hole with their throats slit. 300 officers and Army personnel from Gunung Biru in Tamanjeka withdrew from the area after failing to find Santoso. On 10 July 2013, it was reported Santoso had appeared in a six-minute video posted on YouTube. He described Detachment 88, the Indonesian Special Forces counter-terrorism squad, as "a real enemy, a real Satan". "My brothers in Poso, I have felt how cruel Detachment 88 is to these people," and "Today, God almighty has decided that jihad will continue until judgement day", he says in the video.

Santoso pledged allegiance to ISIL in July 2014. According to the BBC, Bahrum Naim is said to be the main liaison between MIT and IS.
The Jakarta Post reported on 25 March 2016 that, "at least 2,500 military and National Police personnel have been on deployment since January, hunting for Santoso and around 34 of his followers". On 23 June 2016, Muhamad Nasir, former leader of the Mantiqi III, called on Santoso to surrender. "Enough Santoso, get down here, it’s better to turn yourself in, have a sympathy for your family. You have nothing to aim for", he said. In January 2016, there was speculation that Santoso may have been killed after a photograph of a corpse was widely circulated. National Police spokesman Suharsono said the body was not that of Santoso.

Thousands of people, several of whom brandished Islamic State movement flags, attended his funeral. The mass turnout highlighted the extent of support for the Islamic State movement in Indonesia. A banner was erected across a small road leading to the house of Santoso's parents in Landangan village that read, "Welcome the martyr of Poso, Santoso alias Abu Wardah."
