Russia-linked hacker gang claims ransomware attack on McDonald's

A ransomware group linked to Russia has claimed a cyberattack on McDonald's Corporation, as federal officials warn of potential widespread targeting of US businesses after Russia's unprovoked invasion of Ukraine.

The hacker gang Snatch on Friday claimed to have stolen 500 gigabytes of data from the fast-food giant headquartered in Chicago, posting their demand for an undisclosed ransom on the dark web.

The iconic company, which signifies America's economy and culture around the world with more than 38,000 locations in 100 countries, has a market capitalization of $186 billion.

The purported breach comes as the US Cybersecurity and Infrastructure Security Agency issues a 'shields up' alert to all American businesses and organizations, urging them to take measures to protect themselves from potential Russian cyberattack.

The group behind the Snatch ransomware refer to themselves as the 'Snatch Team' and all appear to be Russian-speaking, according to a 2019 report from security firm Sophos. 

The report said that the group behind the ransomware appeared to have been active since the summer of 2018, though they have maintained a fairly low profile, executing few headline-making breaches.

The malware used by the hacker gang is highly sophisticated, and operates by rebooting victim computers in Safe Mode, in which most security measures are deactivated.
