P2P File Sharing

10 to 15 Lines of Code – From P2P to Can You Crack It

Can a few lines of code make a difference?

Apparently, they can. There are several examples that demonstrate that just 10 to 15 lines of code can be rather significant.

Take for example that an entire peer-to-peer file sharing application can actually be written in only 15 lines of code. There's a software available that does this, and simple P2P software such as this can easily be created by a skilled programmer. This just demonstrates the power of programming and how far coding techniques have developed. Nowadays, less lines of code can achieve more.

The same principle can also be found at the Can you crack it? website. In only 10 lines of code, the website challenges you to solve the puzzle in order to reveal the secret keyword. Once you know the secret keyword, you submit it, and are taken to a following page. Visitors are prompted to solve the 10 lines of code within a time limit, and this website further exemplifies how just a few lines of code can be impactful.

P2P Botnets

Just as the centrally based botnets are being taken down by authorities, new peer to peer (P2P) botnets are popping up to replace them. In P2P botnets, each bot, or infected machine, contains additional code that allows it to pass along instructional information.

These networks will be very hard to take down, because no central command is needed. Instructions are fed to just one or two members of the network, and these will pass them along to others, and the process continues until the whole network has been updated and is working as one. In a modified configuration of the P2P botnet, it can set itself up into a hierarchy with instructions coming only from a computer higher up in the hierarchy. This kind of structure would overcome some of the technical difficulties that botnet builders have faced in the past.
