PCMag said:Scammer Uses Fake iPhone Jailbreak for Fraud Scheme

Bleeping Computer said:Scammers Use Fake Checkra1n iOS Jailbreak in Click Fraud Campaign
Scammers have already been spotted baiting Apple users using a recently developed iOS jailbreak dubbed checkra1n as the lure in a campaign designed to help the crooks earn money via click-fraud and boost App Store rankings for several apps.
checkra1n makes use of the Checkm8 jailbreak-enabling iOS bootrom exploit released on Twitter last month by security researcher axi0mX.
As Cisco Talos researchers found, a scam group has noticed the attention this new jailbreak tool has amassed lately and reacted by registering and hosting checkrain[.]com, a "fake website that claims to give iPhone users the ability to jailbreak their phones."
"However, this site just prompts users to download a malicious profile which allows the attacker to conduct click-fraud."
