The German government said on Tuesday that a Chinese cyberespionage group known as APT27 has repeatedly attacked German companies over the past few months using vulnerabilities in software like Microsoft Exchange and Zoho SelfService. The attacks, which have been taking place since at least March 2021, have aimed to install a version of the HyperBro malware inside corporate networks for the purpose of intelligence collection from infected hosts, the Federal Office for the Protection of the Constitution (BfV) said in a press release.
