The article states that a dark matter halo around the earth is considered a plausible explanation for the anomaly. Combine this with the possible "hairy" configuration of dark matter around the earth [1], and it fits in rather well with the inconsistent way in which the anomaly manifests itself: probes are affected differently depending on how close they fly by the root of a dark matter hair.
