In this message, an individual claims to be a member of the said hacker group and has taken credit for the havoc reeked by the WannaCry (pt) ransomware attack that was part of the previous data dump leaked by them.
The group said that it would be launching a serial data dump of hacking tools that supposedly are developed by the U.S. spy company, National Security Agency (NSA).
The Shadow Brokers mentioned that the leaked data could contain web browser, router, handset exploits and tools, newer Ops Disks and exploits for Windows 10, compromised network data from Central banks and compromised network data from Russian, Chinese, Iranian, or North Korean nuclear and missile programs.
WannaCry ransomware attack might have slowed down, but it has managed to infect over 300,000 computers globally, with many businesses and even hospitals losing access to precious data. In the Tuesday letter, they said they weren't "interested in stealing grandmothers' retirement money", but wanted to send a message to the Equation Group, a hacking group linked to the NSA. The group is also promising that June will be the data dump month. It has not responded to repeated requests for comment about the ransomware attack.
NHS cyberattack: Trusts were told about security patch last month
By late morning, some people were still filling out forms manually, but the hospital said 70 percent of systems were back online. Hospitals and GP surgeries in England and Scotland were affected by a ransomware attack, using malware called Wanna Decryptor.
Two months before the WannaCrypt exploit hit the wild Microsoft released a patch, suggesting some cooperation between NSA and the software company.
"While they don't seem to have the most awesome PR department", he said, "they've already proved that they had some pretty serious access". It renewed debate over how and when intelligence agencies must disclose vulnerabilities used in cyber spying programs.
It is unknown whether the Shadow Brokers genuinely have further tools stolen from the NSA or whether the group will make good on its threats. Spokesperson from Microsoft has already said that they will be preparing a response for this claim from the hacking group.
That attempt was also doomed, and after failing to secure buyers for the remainder of the tools they teased, the group dumped online the August 2016 password-protected archive last month in April. Microsoft has connected previous exploits of its products released by the mysterious Shadow Brokers group to tools which were stolen from NSA cyber warfare operations. "Microsoft has been critical of the USA government over this stockpiling of vulnerability code, and said this was equivalent to the government losing it stock of 'Tomahawk missiles".
