FireEye, a US cybersecurity firm, says that it has seen a concerning spike in activity from what appears to be a Chinese hacking group called APT41. The attacks are being deployed against companies in the US, Canada, the UK and several other counties, which is atypical of Chinese hackers’ typical strategy of focusing on a few particular targets. According to FireEye’s report, the group is exploiting software flaws in applications and hardware developed by Cisco, Citrix and others to gain access to target companies’ networks and download files via FTP, among other strategies. According to the firm, the attacks began on January 20th, dipped during the Chinese New Year celebrations and COVID-19 quarantine measures and are now back at full scale, affecting 75 of FireEye’s customers.
