  1. Microsoft Won’t Patch a Severe Skype Vulnerability Anytime Soon

Skype is a telecommunications application software product that specializes in providing video chat and voice calls between computers, tablets, mobile devices, the Xbox One console, and smartwatches via the Internet and to regular telephones. According to the report published by Hacker News, a serious vulnerability has been discovered in Microsoft-owned most popular free web messaging and voice calling service Skype that could potentially allow attackers to gain full control of the host machine by granting system-level privileges to a local, unprivileged user. According to the researcher, a potential attacker could exploit the “functionality of the Windows DLL loader where the process loading the DLL searches for the DLL to be loaded first in the same directory in which the process binary resides and then in other directories. Successful exploitation could allow the attacker to hijack the update process by downloading and placing a malicious version of a DLL file into a temporary folder of a Windows PC and renaming it to match a legitimate DLL that can be modified by an unprivileged user without having any special account privileges.

Cyber Security Tips: Until the company issues an all-new version of Skype client, users are strongly recommended to exercise caution and avoid clicking on attachments provided in an email. Also, make sure you run appropriate and updated anti-virus software that offers some defense against such attacks.
