In months, sites counts a site in every month it matched and newSites only in its first, so newSites sums to sites; the month of asOf is still in progress. Kits overlap on the same sites, so kit counts do not add up to the technique, and kits lists kits on more than one of its sites, not only those with contracts or commands. A kit's counts in that list are for the whole kit across every technique it uses; its threat field names the technique its own page sits under. captured is sites with a successful capture since capturesBegin; wordpress, joomla, wpCore and plugins count among those, so divide by captured for a share. An article's dates can start before recordsBegin. persistence.rechecked is sites captured again at least 25 days after their first match and persistence.still is how many of those still matched, so 0 and 0 means none has been rechecked yet, not that none is infected. persistence counts rechecks from before capturesBegin too, so rechecked can exceed captured. For the clickfix and etherhiding techniques, the 20 busiest command hosts or the 20 newest contracts with the totals; the search tools page through the rest.",

A resolver contract that names further contracts in nextHops lists in destinations the hosts those contracts point to on the latest read, so the same host also appears on the row of the next contract: count hosts once across rows. destinations is empty when the next hop is a WebRTC endpoint, or, when nextHops is empty too, because Ohey has read the contract but recorded no host from it. lastChanged is when its destination last changed. Addresses are lowercase. destinations is what the latest read (lastRead) returned. Chains ending in testnet or Sepolia are test networks; kits read them like any other. nextHops values are defanged too. Set destination to find the contracts that point, or pointed, at a host or a host under it; it also matches the endpoints in nextHops. Each row then carries destinationCurrent, true when the match is in destinations or nextHops now and false when only in history. Destinations hold hosts only, so a URL filter compares its host and not its path. history holds the 20 most recent changes, so a destination older than those does not match.
