Communication mechanism Updated +Created
There are four main types of communication mechanisms found:
  • There is also one known instance where a .zip extension was used! web.archive.org/web/20131101104829*/http://plugged-into-news.net/weatherbug.zip as:
    <applet codebase="/web/20101229222144oe_/http://plugged-into-news.net/" archive="/web/20101229222144oe_/http://plugged-into-news.net/weatherbug.zip"
    JAR is the most common comms, and one of the most distinctive, making it a great fingerprint.
    Several of the JAR files are named something like either:
    • meter.jar
    • bandwidth.jar
    • speed.jar
    as if to pose as Internet speed testing tools? The wonderful subtleties of the late 2000s Internet are a bit over our heads.
    All JARs are directly under root, not in subdirectories, and the basename usually consist of one word, though sometimes two camel cased.
  • JavaScript file. There are two subtypes:
    • JavaScript with SHAs. Rare. Likely older. Way more fingerprintable.
    • JavaScript without SHAs. They have all been obfuscated slightly different and compressed. But the file sizes are all very similar from 8kB to 10kB, and they all look similar, so visually it is very easy to detect a match with good likelyhood.
  • Adobe Flash swf file. In all instances found so far, the name of the SWF matches the name of the second level domain exactly, e.g.:
    http://tee-shot.net/tee-shot.swf
    While this is somewhat of a fingerprint, it is worth noting that is was a relatively commonly used pattern. But it is also the rarest of the mechanisms. This is a at a dissonance with the rest of the web, which circa 2010 already had way more SWF than JAR apparently.
  • CGI comms
These have short single word names with some meaning linked to their website.
Because the communication mechanisms are so crucial, they tend to be less varied, and serve as very good fingerprints. It is not ludicrous, e.g. identical files, but one look at a few and you will know the others.

RNA-Seq Updated +Created
Sequencing the DNA tells us what the organism can do. Sequencing the RNA tells us what the organism is actually doing at a given point in time. The problem is not killing the cell while doing that. Is it possible to just take a chunk of the cell to sequence without killing it maybe?

  • 623463a2a8a949e0590ffe6b2fd3e4e1028b2b99c747e82e899da4485eb0b6be and 5143cf232576ae53e8991ca389334563f14ea7a7c507a3e081fbef2538c84f6e both have 3,075 outputs of 1 satoshi each and a single input. We were not able to identify any meaningful data in it, file just says data, and there aren't long ASCII strings. However, the outputs were unspent as of 2021, which suggests that they might actually be data.
Analysis of some of them follows.
