According to the U.S. Department of Homeland Security, a newly discovered yet old vulnerability, can be used to take control of an infected computer. They are urging users and administrators to apply a patch immediately to prevent the a similar outbreak like WannaCry which infected more than 300,000 computers worldwide.
According to a Reuters article, Rebekah Brown of Rapid7, a cybersecurity firm, said there were currently no signs of attackers exploiting the vulnerability in the twelve hours since it was discovered and announced.
However, she also stated that it had taken researchers only fifteen minutes to develop malware that made use of the vulnerability. “This one seems to be very, very easy to exploit,” she said.
Rapid7 said it had found more than 100,000 computers running vulnerable versions of the software, Samba, which is “… an Open Source/Free Software suite that provides seamless file and print services…” Samba runs on Linux variations as well as some environments with Windows and Mac OS.
Most of the computers found are running older versions of the software and cannot be patched, according to Brown.
