The exploits dumped in April are said to have been stolen from a group known as Equation Group which is reported to have NSA links. These were used by the attackers who crafted WannaCry and the malware that hit Ukraine last week.
At the end of May, the Shadow Brokers, which has been linked to Russia, said that any future exploit dumps would be through subscription. A group of ethical hackers banded together to raise the money to buy anything that was released, but then disbanded after being warned of the legal ramifications of their actions.
In its latest missive, in what has now become its trademark broken English, the Shadow Brokers said the next batch of exploits would cost 200 Zcash units (about US$58,000 at today's rates).
"TheShadowBrokers is thinking 'doctor' person is co-founder of new security company and is having much venture capital. TheShadowBrokers is hoping 'doctor' person is deciding to subscribe to dump service in July," the group wrote.
Otherwise, the group warned, "theshadowbrokers might be taking tweets personally and dumping data of 'doctor' persons hacks of China with real id and security company name. TheShadowBrokers is thinking this outcome may be having negative financial impact on new security companies international sales, so hoping 'doctor' person and security company is making smart choice and subscribe".

Researcher Daniel R. Wolfford of UAE-based security firm DarkMatter apparently thinks he might be the person referred to, for he tweeted, "Apparently @shadowbrokerss threatened me in his new post. 1) don't feed trolls. 2) I was never equationgroup. 3) let's meet in Vegas."
The Shadow Brokers also announced the setting up of a VIP service wherein for the one-time payment of 400 Zcash units, one would get receive all future exploit dumps.
