i don't think it's gonna be anything specifically malicious. it's just plain old domain squatting. "oh it's a different name, but maybe they will pay us to transfer it to them"
malicious in the sense that they are making a calculated guess that a unique name that isn't registered that has some registered might be rich and then they will not care to spend $500 to nail down this one which isn't as ideal but ok.
the monopoly on TLD is the suck. you sholud be seedsigner. as in like www.seedsigner.
