BANGKOK (AP) — Amnesty International says it has found that a hacking group known as Ocean Lotus has been staging more spyware attacks on Vietnamese human rights activists in the latest blow to freedom of speech in the communist-ruled country. The human rights group said Wednesday that Amnesty Tech’s Security Lab found evidence of the hacking attempts in phishing emails sent to two dissidents, one in the Philippines and one in Germany. Cybersecurity firms earlier identified hacking attempts by Ocean Lotus targeting dissidents, governments and companies across Southeast Asia. The hackers are suspected of having ties to Vietnam’s government, which has been cracking down on dissent. Amnesty urged the Vietnamese government to investigate.
