A SIM farm could have knocked out New York. But what are they?

The US Secret Service has just dismantled a SIM farm powerful enough to knock out New York’s entire cellphone network. It linked more than 100,000 SIM cards and could send 30 million texts every minute, say officials – and it was being used to conduct encrypted conversations between hostile state-backed groups and cybercriminal gangs. Here’s how it worked. Tackling cybercrime demands a global, cross-sector response. The World Economic Forum’s Partnership Against Cybercrime launched the Cybercrime Atlas to map cybercrime networks and boost coordination between the private sector and law enforcement.
