Cybersecurity officials in the administration of US President Joe Biden have warned that hundreds of millions of devices are at risk of a software problem, and that hackers may exploit it.
Experts and officials are asking organizations to look inside their systems to try and find vulnerabilities, and if they find it, correct it or mitigate it in some way.
According to what was published by the American "CNN" network, it is suspected that Chinese hackers exploited this vulnerability, which is in a program known as Log4j, and it is widely used by well-known companies such as Microsoft and Amazon Web Services.
The vulnerability allows hackers to gain access to systems, followed by accessing a user's computer and controlling applications in it.
Jane Easterly, director of the Cyber Security Agency, said: "This vulnerability is one of the most dangerous, if not the most dangerous, I've seen in my entire career. We expect it to be exploited by professionals, and we have limited time to take steps to reduce the possibility of accidents. harmful".
