SEOUL (Reuters) -SK Telecom shares fell as much as 8.5% on Monday to hit their lowest level since August last year, after South Korea's biggest mobile carrier disclosed it suffered a leak of customer data earlier this month caused by a cyberattack.
The company said in a statement it would take full responsibility for any harm caused as a result of the breach that was detected on April 18. It described the incident as a large-scale leak of data due to malware, without providing more details.
