CERT-SE:s veckobrev v.14

Under veckan har det skrivits om två större läckor från sociala medier. Förra veckan angreps även flera EU-institutioner och det rapporterades om problem med alkolås. Den här helgen är det dags för Midnight Sun CTF, Sveriges största internationella cybersäkerhetstävling. För den som vill ha en utmaning är det fortfarande möjligt att anmäla sig, länken hittar ni under Informationssäkerhet och blandat.

Trevlig helg önskar CERT-SE!
