A couple of hours before U.S. House Speaker, Nancy Pelosi was expected to visit Taiwan, several Taiwanese government websites were down.
This cyberattack was reported shortly before Pelosi's plan to visit Taiwan, with its controversial relations with China, claiming it as its own. Therefore, the Chinese government threatened to act if the visit happens.
On Tuesday evening, the official websites of Taiwan's government and its presidential office were blocked from use. It was confirmed by the office spokesperson that the president's site was hit by an overseas malware attack. It was restored after 20 minutes.
