At first this challenge may not make sense in English, but we can assume that IM means Instant Message. A quick Google search of 4046925 returns interesting results for
“NSA DOCID: 4046925 Untangling The Web: A Guide To Internet Research”
Since we are looking for Instant Message information, a quick text search within the 651 page document for “Instant Message” returns a hand full of results. Pan through to the 3rd result to find:
“Instant messaging generates five billion messages a day (750GB), or 274 Terabytes a year.”
Since we are looking for the yearly amount, we MD5(274) => d947bf06a885db0d477d707121934ff8 and turn in our flag: ASIS_d947bf06a885db0d477d707121934ff8
