From the article:
“All of the sites in question were accessible through the Tor network, which according to those involved with the investigation was compromised by means of an as-yet-undisclosed tool or mechanism.”
From the article:
“Other markets, including Agora, Middle Earth and Evolution, remain unaffected at press time.”
If that continues to be the case then it is evidence that they HAVE NOT actually cracked Tor itself but that the success of the attacks on the other sites was due to some operational failures on the part of the sites.
