Excerpted from another article about the claim:

------------------------------------------------------------------------

" I asked Gerck if this was theoretical, or if they had cracked RSA-2048 
in a real-world setting, if they planned to demonstrate this to any 
quantum computing experts who might vouch for their findings, and when 
their peer-reviewed findings would be published. He responded, 'We broke 
a public RSA-2048. We cannot risk impersonation.'"

Woodward, after reviewing the Gercks' research paper, said it appears to 
be "all theory proving various conjectures - and those proofs are 
definitely in question." He added, "I'll believe they have done this 
when people can send them RSA modulus to factor and they send back two 
primes. Until I see that, I'm just confused and not convinced they've 
done what they claim in the headlines."

Anton Guzhevskiy, the chief operating officer at Australian 
cybersecurity firm ThreatDefence, also challenged Gerck to prove his 
claims. "I've shared an RSA-2048 public key and a corresponding private 
key encrypted by this public key. If you can decrypt the private key, 
you can sign some piece of text with it, which will prove that you are 
in possession of the private key," he said in a response to Gerck's post 
on LinkedIn. "Can you do it?" "There is a publication delay, and I do 
not control that," Gerck responded.

------------------------------------------------------------------------

It appears that the claim is without  merit.
