The Wall Street Journal reported that ex-intelligence officials said the Brokers were exposing the names of hackers and this could expose these individuals to charges in other countries.
It cited a blogger named Marcy Wheeler who wrote that the Shadow Brokers had exposed the identities of four NSA people in the metadata of the exploits which were dumped in April.
But Wheeler added at the start of the post that she had not confirmed the names and IDs released in the dump were those of NSA hackers.
The WSJ reported that a fifth person, an ex-NSA employee named Jake Williams, had been under threat of public exposure in several public tweets sent by the Shadow Brokers, who had written an article speculating that the Brokers have links to Russia.
There is an unspoken agreement between governments that the names of state-employed hackers are kept from the public gaze, in order to avoid putting these individuals in difficulty when they travel abroad, as their activities could often contravene laws in other countries, it said, citing ex-intelligence officials.
But again, there was no certainty on this claim either, with the report citing the head of a cyber security company as saying that the Shadow Brokers could also have not bothered to redact the names because they simply didn't care about concealing what was sensitive information as far as the US government was concerned.
Williams told the newspaper that the Shadow Brokers was doing what the US had already done: revealed the names of hackers who worked for foreign countries.
The Shadow Brokers has threatened further exposures next month and Williams fears that more information about him and other ex-government hackers may be released.
