Yahoo HackIntroduction The hack involved Yahoo Company and happened in 2017 following other recent hacksreported by the company quietly (Das, Dabbish & Hong, 2018, April). The data breach thathappened in 2013 August involved more than 1 billion user accounts which were laterdiscovered that all the 3 billion user accounts were involved. The company that was greatlyaffected was Verizon which was purchasing yahoo for a deal of $4.8 billion (Crabb, 2017). This hack was noticed to the users through yahoo official notification sent to Yahooaccounts holders and read "Based on the ongoing investigation; we believe a forged cookie mayhave been used in 2015 or 2016 to access your accounts" (Solove& Schwartz, 2014).However, it was not clear what total number of customers were affected since thecompany did not know the exact number and also had only realized it after the long period justlike in the case of 2013 breach that involved more than 3 billion accounts users(Solove&Schwartz, 2014). The company linked the hack to have been facilitated by the state actorthrough use ofsophisticated cookie(Sengottuvel,Hussain& BIST). This hack deserves close attention because it involves a majority of people who send andreceive very private and confidential information using yahoo email accounts. The information iscrucial for Companies and may be used to deny them benefits in the markets if seen bycompetitors(Crabb, 2017).
