How OIETIF Virus Works

This meme inspired by @SENTRY456123 and @Tipsy_D is also a simplified reveal of how OIETIF (my hardware bricking/“destroying“ trojan) actually works. Watch the video about OIETIF first if you don’t know what this is: It does in fact not do anything to the BIOS - while this could be possible, it is highly dependent on the actual hardware and usually protected against. Instead, OIETIF uses the easy-to-implement SMBUS interface to try to write to the SPD (serial presence detect), a small flash chip inside every DIMM (RAM module) that tells the system about its capacity and timings. Systems of the XP-Win7 era often weren’t protected against writing to this chip. Even newer systems can be affected, although rarer. There are also legit uses to writing the SPD such as overclocking when the BIOS doesn’t support adjusting timings. To not require complicated writing of Windows drivers, OIETIF instead writes its own small program into the boot sector and reboots the machine. This program then shows the “Please wait...“ screen, while writing to all known addresses in the SMBUS that are usually connected to the DIMMs. After that, it shows the DEATH screen and halts the CPU. When the user now reboots the machine, the BIOS only gets garbage data from the SPD and therefore refuses to boot. In the case of this laptop, it simply hangs. In other cases, it will beep to indicate memory detection issues. Remember that OIETIF is just a proof of concept for the bricking part of ÿ. ÿ includes a visual Windows payload and a game that - if won - will recover the SPD before powering off the machine. About the name OIETIF - I don’t know what it means myself. It used to be the first letters of each instruction from an early version of the game, but these original instructions have been scrapped and only this name survived.

But nowadays “virus“ is a typical word used for all kinds of malware, even if they are not an actual file-infecting virus. Also I kinda like the self irony of calling it a virus. It fits this meme better. Since MEMZ also is a cringy piece of sht, I ironically call it “Memms Veerus“ instead of “Memes Trojan“ as well.
