Though Zoom is an efficient online video meeting solution, it's still not the best choice in terms of privacy and security. According to the latest finding by cybersecurity expert  @_g0dmode , which was also  confirmed  by researcher Matthew Hickey and  Mohamed A. Baset , the Zoom client for Windows is vulnerable to the ' UNC path injection ' vulnerability that could let remote attackers steal login credentials for victims' Windows systems The attack involves the SMBRelay technique wherein Windows automatically exposes a user's login username and NTLM password hashes to a remote SMB server when attempting to connect and download a file hosted on it. The attack is possible only because Zoom for Windows supports remote UNC paths, which converts such potentially insec...

Cybersecurity researchers today uncovered a sustained malicious campaign dating back to May 2018 that targets Windows machines running MS-SQL servers to deploy backdoors and other kinds of malware, including multi-functional remote access tools (RATs) and cryptominers. Named " Vollgar " after the Vollar cryptocurrency it mines and its offensive "vulgar" modus operandi, researchers at  Guardicore Labs  said the attack employs password brute-force to breach Microsoft SQL servers with weak credentials exposed to the Internet. Researchers claim the attackers managed to successfully infect nearly 2,000-3,000 database servers daily over the past few weeks, with potential victims belonging to healthcare, aviation, IT & telecommunications, and higher education sectors across China, India, the US, South Korea, and Turkey. Thankfully for those concerned, researchers have also  released a script  to let sysadmins detect if any of their Windows MS-SQL servers have b...
