CERT-SE:s veckobrev v.31

Efter en färgglad vecka med både Pride och uppdatering av TLP kommer här lite omvärldsbevakning från CERT-SE. Det har rapporterats om ett antal olika angrepp, bland annat överbelastningsattacker och utpressningsvirus. Dessutom blir det som vanligt några djupdykningar i olika typer av skadlig kod.

Trevlig helg önskar CERT-SE! 🏳️‍🌈
