Investors lost billions after cyberattacks

london - Investors Since 2013 more than 42 billion pounds lost by cyber attacks and data breaches by UK listed companies. That converts more than 49 billion euros.

Consultant CGI and research from Oxford University have calculated the damage. They examined 65 British companies and used before a list of incidents from the Dutch Gemalto. They looked at the share price of a company after the announcement of an incident and laid it next to the price of comparable companies.

The conclusion is that shares are structurally average 1.8 percent less valuable after a digital intrusion. That costs the investor for an average company 120 million pounds (141 million euros).

Financial companies are the worst hit after a cyber attack, followed by the communications sector. Retail and travel companies get the best out of an attack.
