Meanwhile, they also found 13 credential pairs in the more recent “compilation of many breaches”– COMB for short - that occurred just days before the attack.
Researchers at CyberNews said they found 11 credential pairs linked to the Oldsmar water plant, in a 2017 compilation of stolen breach credentials. Let us know your thoughts in the comments.Researchers say they found several stolen and leaked credentials for a Florida water-treatment plant, which was hacked last week.
Users must ensure updating their devices with the patched version to stay safe. Consequently, TeamViewer has fixed the bug with the release of TeamViewer 11 v97, TeamViewer 12 v99, TeamViewer 13 v6, and TeamViewer 14 v. However, TeamViewer later explained Microsoft’s denial to patch the bug and fixed the flaw themselves. Following this discovery, they reported the matter to TeamViewer who then clarified informing Microsoft of the matter since the problem existed because of a Microsoft component. SafeBreach Labs found this vulnerability in July 2019 as they targeted TeamViewer 14. Thus, because of the problem with Microsoft’s DLL library (mswsock.dll), it became possible for an attacker to load arbitrary DLLs and execute code.
The library tried to load the mentioned DLL files using LoadLibraryExW without flags. Once the service is loaded, it calls the WSAStringToAddressW WinAPI function (which causes the process to load the ws2_32.dll library) Next, the ws2_32.dll library loads the mswsock.dll library, and after a few calls it gets to the SockLoadHelperDll function, which tries to load wshtcpip.dll using LoadLibraryExW. Then, due to the absence of signature validation and an uncontrolled search path, the service could load unsigned DLLs. It occurred due to the TeamViewer service tried to load a missing DLL file with every restart. This time, they have found the vulnerability in TeamViewer that could allow code execution.Īs elaborated in their blog post, the vulnerability exists in TeamViewer Client For Windows versions 11 to 14. SafeBreach Labs researchers have found another noteworthy vulnerability in popular software. As discovered, the bug, upon an exploit, could allow an attacker to execute arbitrary code on the device. Heads up TeamViewer users! A vulnerability in the TeamViewer has recently received a fix.
