Some cyber experts opportunity nan hackers show nan traits of Scattered Spider, a loose organization of often young individuals who organise crossed sites for illustration Discord, Telegram and successful forums, astir apt located successful nan UK and US.
Although nan NCA says it is exploring each parts of nan cyber crime ecosystem, it excessively is looking successful nan aforesaid direction.
"We cognize that Scattered Spider are mostly English-speaking but that doesn't needfully mean that they're successful nan UK - we cognize that they pass online amongst themselves successful a scope of different platforms and channels, which is, I guess, cardinal to their expertise to past beryllium capable to run arsenic a collective," Mr Foster said.

NCA investigators will not opportunity really nan hackers person managed to breach unfortunate organisations but earlier this month, nan National Cyber Security Centre issued guidance to organisations urging them to reappraisal their IT thief table password reset processes.
"Calling up IT thief desks is simply a maneuver that Scattered Spider seems to favour and they usage societal engineering techniques to manipulate personification into doing thing for illustration clicking connected a nexus aliases resetting someone's relationship to a password they tin use," Lisa Forte from cyber information patient Red Goat said.
In nan BBC documentary, a erstwhile teen hacker who was arrested 9 years agone and now useful successful cyber security, said he was not amazed that teenagers could beryllium down nan hacks.
"It wouldn't astonishment maine - rather [the] opposite. The devices are readily disposable and it's very easy to jump online and hunt consecutive away. You tin consciousness a spot untouchable but for what end? You're gonna beryllium arrested 99% of nan time," he said.
