A mobile phone has been discovered during an investigation. Authorities have extracted a dump from the phone, but crucial information is missing.
Your mission is to retrieve the following information:
- The
weight(in grams, rounded to the nearest unit) of the phone. - The
serial number(SNR) of the phone. - The
time(hh:mm:ss) of the last call made to the number023546789.
The flag is in the following format: ECW{md5(weight-serialnumber-calltime)}.
For example, if:
- weight =
92g - serial number =
471636 - calltime =
22h30 and 42 seconds
the flag will be constructed as follows: md5(92-471636-22:30:42), which gives the flag ECW{59da29c226c05915b078f6455b2c6a42}.
