Things you need to worry about

Zscaler ThreatLabZ observed compromised Olympics-themed websites that redirect visitors via injected scripts and EITest gates to RIG and Neutrino exploit kits, resulting in Qakbot infections (backdoor/infostealer) and CryptXXX ransomware deployments; the report details the exploitation chain (malicious jquery injection, SWF exploit, XOR-encrypted payload), observed behaviors (service-based persistence, shadow copy deletion), provides telemetry (Neutrino activity), and recommends mitigations such as enabling click-to-play, keeping Flash/OS/browser patched, using ad-blockers, 2FA, and regular backups.
