Stolen network information from Russian, Chinese, Iranian, and North Korean nuclear missile programs.
While the Shadow Brokers has stressed the financial value of the stolen hacking tools it holds, in its response to the WannaCry attack it repeatedly states that its aim "is always being about theshadowbrokers vs theequationgroup". Each month peoples can be paying membership fee, then getting members only data dump each month.
In the blog post, the group said it was setting up a "monthly data dump" and that it could offer tools to break into web browsers, network routers, phone handsets, plus newer exploits for Windows 10 and data stolen from central banks.
No one appears to have paid the Shadow Brokers for access to the Equation arsenal in the past, at least as far as it's publicly known.
The cyber security community has been combing through the blog post and other indicators for the Shadow Broker's intentions.
"ShadowBrokers are back" tweeted Matthieu Suiche, a French hacker and security researcher who has tracked the group. But the naming of Windows 10 specifically will undoubtedly set Microsoft, its partners and corporations using the latest version of Windows, which until now has been unaffected by WannaCry, on edge.
The leaks, and the global WannaCry virus attack, have renewed debate over how and when intelligence agencies should disclose vulnerabilities used in cyber spying programs to so that businesses and consumers can better defend themselves against attacks.
A spokesman for the group, which calls itself Shadow Brokers, claimed in a blog post on Tuesday that some of those computer bugs may be released on a monthly basis, as part of a new subscription-based business model that attempts to mimic what has proven successful for companies such as Spotify, Netflix, Blue Apron and many more.
"Because simply by threatening another leak after leaking two sets of Microsoft exploits, Shadow Brokers will ratchet up the hostility between Microsoft and the government".
"Repeatedly, exploits in the hands of governments have leaked into the public domain and caused widespread damage." - said Microsoft's Brad Smith - "An equivalent scenario with conventional weapons would be the USA military having some of its Tomahawk missiles stolen".
