Type the keyword “zalo web” into the search engine, the top results always have 2 addresses “zaloweb.me” and “zaloweb.vn”.

To deceive users, the websites are disguised as Zalo's real homepage, making it difficult to distinguish between real and fake, with instructions on how to log in on the computer in many different ways.

However, if you click on the "login zalo on the web" button, depending on the time, users will be redirected to football betting advertising pages, adult content or pages containing viruses.

Normally, to avoid detection, hackers still allow users to redirect access to the real Zalo homepage, https://zalo.me/.

Mr. Vo Duy Khanh, an expert from Bkav, said: “We have been monitoring for a while, sometimes bad guys install viruses or display unhealthy content, sometimes they point to the real Zalo homepage address. However, with the need to use Zalo on computer browsers in agencies and offices, there are still a large number of users searching for “zalo web” every day and then accessing the fake page, this is a serious threat to national security.

"Bkav has sent a report to the Ministry of Information and Communications to block these malicious websites. This is not Zalo's problem, but this national chat application is being exploited by bad guys," said the expert.

Bkav experts recommend that anyone who accidentally accesses the above fake websites should immediately scan for viruses to ensure network security.
