CYBER CRIME TODAY<br />
CASE STUDY: TALKTALK TELECOM<br />
In October 2015, the telecommunication company was forced to warn all<br />
four million customers that their data may have been stolen, after hackers<br />
acquired the personal and banking details belonging to a number of TalkTalk<br />
customers. Overall, the breach affected 157,000 customers with 21,000 bank<br />
account details, 28,000 credit card details and 15,000 dates of birth stolen<br />
during the cyber-attack. 3 The breach inflicted immediate reputational damage<br />
upon the company and it was forced to temporarily close down its online sales<br />
and services channels. Consequently, the financial impact of the breach was<br />
substantial, with the company attributing the attack to 94% of the 101,000<br />
customers lost and a £60 million decline in profits in the following quarter of<br />
the financial year. 4 The value of the company fell by 16% on the day of the<br />
announcement and has not recovered since due to the subsequent impact<br />
on the company’s financial performance and competitive positioning.<br />
