Target: QuickCrypto’s QuickStego Version 188.8.131.52
QuickStego is a tool that can hide unencrypted text data in BMP image files.
The first look with PEiD reveals a Visual Basic executable, the crypto analyzer tells us something about CRC32. This may be used as some kind of verification of the data.
SDRAM DIMMs have a standardized way of storing configuration data in an on-chip EEPROM. In this case the EEPROM is a 24C02, 256 Byte one. The storage of information in it is defined by the Serial Presence Detect - SPD standard. It integrates into the SMBus when plugged into a computer, and the BIOS uses the data contained to initialize memory access.
The next „real small program“ is a SFV Verifying utility. It’s without doubt the smallest one flying around in the interwebz, and also one of the fastest, if not the fastest :) (ironically my quick tests showed it’s faster than both QuickSfv and RapidSfv hehe)
Finally coded something in assembly again!
A fully functional alternative to Windows Service Manager in only 11kB of uncompressed executable :)
