Hackers caught targeting Vietnam government portals By Luu Quy April 10, 2021 | 11:49 am GMT+7 The National Cyber Security Center said it has discovered and foiled a number of attempted cyberattacks on Vietnamese government portals by the China-linked Cycldek hacker group. It said the advanced persistent threat (APT) hacker group is also known as Goblin Panda, Hellsing, APT27, and 1937CN. The Department of Information Security joined hands with Internet service providers to block multiple attacks in March after receiving information from the center that Cycldek was trying to penetrate computer systems in Vietnam, Thailand and Central Asian countries. After identifying the evasion techniques the hacker group used, the NCSC contacted eight Internet service providers in Vietnam and told them to block all the IPs and domains it sent in a list to prevent cyberattacks.
