The only information that Acrobat discloses is that the title of the document is
DES-21Multi Ver.1.13 - 1_0709_D_MC-880_Z2_320_310_A07_00003857.tdd. Perhaps it refers to a program called DES-21Multi, version 1.13 (never heard of it).
Acrobat's "Document properties" reveals no further information about your PDF. You might want to ask the person who sent it.
