Cybersecurity scientists have found a established of 11 dwelling-off-the-land binaries-and-scripts (LOLBAS) that could be maliciously abused by threat actors to carry out write-up-exploitation pursuits.
“LOLBAS is an attack technique that makes use of binaries and scripts that are by now aspect of the system for destructive functions,” Pentera security researcher Nir Chako explained. “This would make it really hard for security teams to distinguish amongst genuine and destructive pursuits, given that they are all performed by trusted program utilities.”
To that close, the Israeli cybersecurity organization claimed it uncovered 9 LOLBAS downloaders and three executors that could empower adversaries to down load and execute “more sturdy malware” on infected hosts.
This incorporates: MsoHtmEd.exe, Mspub.exe, ProtocolHandler.exe, ConfigSecurityPolicy.exe, InstallUtil.exe, Mshta.exe, Presentationhost.exe, Outlook.exe, MSAccess.exe, scp.exe, and sftp.exe.
“In a finish attack chain, a hacker will use a LOLBAS downloader to obtain far more strong malware,” Chako stated. “Then, they will consider to execute it in a stealthy way. LOLBAS executors permit attackers to execute their destructive equipment as component of a authentic seeking method tree on the system.”
That stated, Pentera pointed out that attackers could also use other executables from software outdoors of all those linked to Microsoft to achieve comparable targets.
The results come as Vectra disclosed a prospective new attack vector that leverages Microsoft Entra ID (beforehand Azure Energetic Directory) cross-tenant synchronization (CTS) aspect to aid lateral movement to other tenants assuming a privileged identification has now been compromised in the cloud ecosystem.
“An attacker functioning in a compromised atmosphere can exploit an existing CTS configuration tenant to shift laterally from a person tenant to an additional linked tenant,” the business said. Alternatively, “an attacker operating in a compromised tenant can deploy a rogue Cross Tenant Entry configuration to maintain persistent access.”
