Which of the following sentences is the odd one out after rearrangement?

The correct order is DAFEB. 'D' is the introductory sentence which introduces the subject discussed in the remaining sentences i.e. 'security breach in the world of cryptocurrency'. Sentence 'D' is followed by 'A' which introduces one of the ways to breach security i.e. 'Crypto Jacking'. 'FEB' form a block as the three sentences talk about how crypto jacking is done. 'F' says miners secretively drop malware in user's computer. 'F' is followed by sentence 'E' which says as the crypto mining code is installed through malware it turns the device into mining botnet. Then 'E' is followed by 'B' which says that after the mining is done, the digital assets are stored in ledgers. Sentence 'C' is the odd one odd as it talks about 'Graboid' which is nowhere discussed in the other sentences. After rearrangement, 'C' is the odd one out sentence.
