The FBI has issued warnings regarding the ongoing threat posed by a ransomware attack known as 'Ghost,' which has been linked to North Korean IT workers and a Chinese hacker group. The agency highlighted that these attacks are targeting US-based businesses and could lead to the extortion of sensitive data. In response to the threat, the Cybersecurity and Infrastructure Security Agency (CISA) and the FBI have urged security teams to patch exploited vulnerabilities and segment their networks to mitigate risks. The Ghost ransomware has reportedly compromised organizations across more than 70 countries, raising concerns about its potential to obtain personal data from mobile devices.
