Ah, interesting detail. Yes, the picture on their website also looks like there is a bigger step up to the hatch. Of course could be a slight change in manufacturing, but seems quite suspicious.
So my next attempt at cheap attenuator is

Way better chance to get originals - when buying from big used equipment stores like this one (23k sales, 100% positive).
IMHO it would be good to contact Pasternak to confirm it is fake or not. If it turns out to be fake, you can open a claim on Ebay and get your money back.
My rule of thumb is "don't buy anything I really care about on ebay/aliexpress/amazon".
Hasn't failed me so far!
Dumping 10W @ 6GHz sounds like it should be expensive, IMO.
Is there any chance your amplifier also has a DC on its output?
It's a TWA amplifier, so probably not, but I am not an expert on them. Tested it now using the 50W Anritsu attenuator and everything seems fine, the attenuator does not get that hot. Based on this picture
https://www.rfpage.com/rf-attenuators-how-to-choose-a-proper-one/ the construction of the *Pasternack* attenatuator seems proper. So if it is a fake, it could be only in the materials used in chip resistors, would be hard to verify.
I've accidentally came across a youtube video where the poster used a smartphone app to camera scan one of the brand name sneakers he was buying and the app tells if it is a fake. There was no details given what features the app examined.
