The security official expressed certainty that SWIFT is undoubtedly concerned about the security of its members and said it has an entire program designed for this.
In April, media reported that the Shadow Brokers planned to release data from SWIFT-using banks, as well as from the nuclear programs of Russia, China, Iran and North Korea.
The Shadow Brokers hacker group first appeared in the summer of 2016 and has since then published several leaks of information connected to the US National Security Agency (NSA). It also claimed to have hacked the Equation Group, an elite cyberattack group associated with the NSA and allegedly involved in the creation of the Stuxnet worm that attacked the Iranian nuclear program in 2010.
