Beijing Jiankangbao, a mobile-based app used to check health codes and provide nucleic acid testing results during the COVID-19 epidemic, has been attacked by overseas hackers according to Wei Bin, an official from the capital’s municipal government.

"The Beijing Jiankangbao was attacked on Thursday morning during its peak visiting period. The team of technicians fixed the problems swiftly," Wei said at a news conference on Thursday afternoon. "We later found out the source of the attack was from overseas," she added.

Wei said during the 2022 Beijing Winter Olympics, Beijing Jiankangbao was also attacked similarly by overseas hackers.

According to the city authority, Beijing Jiankangbao has provided more than 13 billion health code results as of February this year.
