Information about the breach apparently came from an investigation involving external consultants that was initiated after unauthorised activity was discovered on the company’s network.
“While we were able to close off access quickly after identification, our investigation has determined that a small number of files were accessed, some of which contained personal data,” McDonalds reportedly said in a statement.
Cyberattacks have been increasing at an alarming rate, with their targets and consequences growing exponentially bigger. Last month, a ransomware attack on Colonial Pipeline in the US crippled fuel supplies in a large swath of the country for days. Later, hackers using ransomware struck at the world’s largest meat supplier JBS, temporarily paralysing some company operations in Australia, Canada, and the US.
Unsurprisingly, the ability of cybercriminals to attack critical infrastructure and critical industries is a top worry in Washington and other Western capitals right now. Many of these cyberattacks have been linked to Russia or hackers based in Russia – a country that has undoubtedly poor relations with America.
