+STEGANO task1:
+
+First of all, it was necessary to run binwalk:
+binwalk 'task1.jpg' -e
+
+DECIMAL       HEXADECIMAL     DESCRIPTION
+--------------------------------------------------------------------------------
+0             0x0             JPEG image data, JFIF standard 1.01
+41561         0xA259          Zip archive data, encrypted at least v1.0 to extract, compressed size: 32, uncompressed size: 20, name: first_flag.txt
+41765         0xA325          End of Zip archive
+41787         0xA33B          PNG image, 759 x 141, 8-bit/color RGB, non-interlaced

+Binwalk could only pull out the zip archive, which turned out to be password-protected
+But we see PNG signature there, try to extract by hands, and find image with password for archive, open archive.
