Our threat intelligence this week highlighted the novel techniques that are being implemented across the threat landscape to produce more effective campaigns. For example, a new Iran-affiliated espionage group TA453 has been observed utilising several fake personas in the same email conversation with targets to increase the authenticity of the correspondence. This technique, dubbed Multi-Persona Impersonation (MPI), was used to impersonate legitimate individuals at Western foreign policy research organisations to deliver malicious documents via OneDrive links.
Meanwhile, cybercriminals have employed a Browser-in-the-Browser (BitB) phishing technique to steal user credentials from the gaming platform Steam. In comparison to typical phishing sites which open in a new tab, BitB creates a fake browser pop-up window that is rendered within the active tab of the phishing website. The pop-up impersonates the legitimate login portal for Steam, tricking users into inputting their credentials. It is possible this technique will be used more widely to impersonate other well-known services, such as Microsoft or Google, to harvest credentials and Multi-Factor Authentication codes.
A vulnerability (CVSS: 10|OVSS: 40) in the authentication functionality of Cisco Wireless LAN Controller (WLC) Software that is currently being exploited in the wild. This vulnerability could allow an unauthenticated, remote adversary to bypass authentication controls and log in to the device with crafted credentials through the management interface as an administrator.
A remote code execution vulnerability (CVSS: 9.8|OVSS: 29) in Windows Internet Key Exchange (IKE) Protocol Extensions. If exploited, an unauthenticated remote adversary could send a specially crafted IP packet to a target machine running Windows and has IPSec enabled, thereby enabling remote code execution.

What is OVSS?
The Orpheus Vulnerability Severity Score (OVSS) helps companies understand the risk associated with particular vulnerabilities. Orpheus does this by adding additional context on the likely threat to and impact of CVEs, building upon the vulnerability information that is provided as part of the CVSS (Common Vulnerabilities Scoring System) score.
