UK authorities are looking into whether a trading outage at the London Stock Exchange (LSE) last August, which was blamed on a software update, may have been caused by a cyberattack, the Wall Street Journal has reported.
The paper, citing sources familiar with the matter, said the LSE has been contacted in the past two months for additional information about the outage.
Trading on the London Stock Exchange was delayed for more than an hour on 16 August, the longest outage in more than eight years.
At the time, the LSE blamed the delay on a “technical software issue”.
