Cybersecurity specialists at ESET discovered that unidentified menace actors created a number of malicious touchdown pages, all impersonating main applications, together with some which are unavailable in China, together with Firefox, WhatsApp, Sign, Skype, and Telegram.
The touchdown pages are all hosted on the identical server, which additionally hosts the applications. However when downloading the payload, the victims would get each the legit software program, and FatalRAT, a distant entry trojan that permits the menace actors management over the goal endpoint.

Researchers couldn’t reproduce the search outcomes however declare that the hackers have been most likely engaged in URL hijacking:
“Though we couldn’t reproduce such search outcomes, we imagine that the advertisements have been solely served to customers within the focused area,” stated ESET researcher Matías Porolli. “Since lots of the domains that the attackers registered for his or her web sites are similar to the legit domains, it’s also potential that the attackers depend on URL hijacking to draw potential victims to their web sites,” he added.
The hackers’ endgame is unknown, too, researchers stated, speculating that they might simply be after credentials, to be able to promote them for revenue.
