The hacking group that says data they released facilitated the WannaCry ransomware attack has threatened to leak a new wave of hacking tools they claim to have stolen from the US National Security Agency.
The so-called Shadow Brokers, who claimed responsibility for releasing NSA tools that were used to spread the WannaCry ransomware through the NHS and across the world, said they have a new suite of tools and vulnerabilities in newer software. The possible targets include Microsoft’s Windows 10, which was unaffected by the initial attack and is on at least 500m devices around the world.
In a blog post written in their trademark broken English, the group said they had more so-called Ops Disks, which they said were also stolen from the NSA. They also claimed to have exploits for web browsers, routers, smartphones, data from the international money transfer network Swift and “compromised network data from Russian, Chinese, Iranian, or North Korean nukes and missile programs”.
In the post, which will worry security agencies and companies worldwide, the Shadow Brokers said: “In June, TheShadowBrokers is announcing ‘TheShadowBrokers Data Dump of the Month’ service. TheShadowBrokers is launching new monthly subscription model. Is being like wine of month club. Each month peoples can be paying membership fee, then getting members only data dump each month. What members doing with data after is up to members.”
The hacking group said they would release tools to subscribers each month or would “go dark permanently” if the “responsible party” bought all the tools for a lump sum, suggesting the Shadow Brokers could be willing to hand over stolen hacking tools to the NSA for a price.
While the Shadow Brokers’ motives remain unknown, they claimed they were not interested in the bug bounties paid by software firms for vulnerabilities found in their code or selling to “cyber thugs”. They said they were “taking pride in picking adversary equal to or better than selves, a worthy opponent” and that it was “always being about theshadowbrokers vs theequationgroup [a sophisticated hacking team believed to be operated by the NSA]”.
The cybersecurity community has been combing through the blog post and other indicators for the Shadow Brokers’ intentions. “ShadowBrokers are back,” tweeted Matthieu Suiche, a French hacker and founder of the United Arab Emirates-based cybersecurity firm Comae Technologies, who has studied the Shadow Brokers’ releases and believes the group has access to NSA files.
Shadow Brokers came to public attention in August 2016 when they mounted an unsuccessful attempt to auction off a set of older cyber-spying tools they said were stolen from the NSA. The leaks, and the global WannaCry ransomware attack that followed, have renewed debate over how and when intelligence agencies should disclose vulnerabilities used in cyber-spying programs so that businesses and consumers can better defend themselves.
The WannaCry attack stoked fears that the spy agency’s powerful cyber weapons could now be turned to criminal use, ratcheting up cybersecurity threats to a new level. The NSA has not commented on Shadow Brokers since the group emerged last year, or on the contents of past leaks or Friday’s ransomware attack.
It is unknown whether the Shadow Brokers genuinely have further tools stolen from the NSA or whether the group will make good on their threats. But the naming of Windows 10 specifically will undoubtedly set Microsoft on edge, as well as its partners and corporations using the latest version of Windows, which until now has been unaffected.
In her analysis of the Shadow Brokers’ threat, independent security researcher Marcy Wheeler wrote that “simply by threatening another leak after leaking two sets of Microsoft exploits, Shadow Brokers will ratchet up the hostility between Microsoft and the government”.
Microsoft said on Tuesday it was aware of Shadow Brokers’ most recent claim and that its security teams monitor potential threats in order to “help us prioritise and take appropriate action”. Microsoft’s president and chief legal officer, Brad Smith, said earlier this week the WannaCry attack used elements stolen from NSA cyber-warfare operations. The US government has not commented directly on the matter.
