## **Respond Quickly to Phishing Campaign Targeting Diplomats**

Unit 42 recently [reported](https://unit42.paloaltonetworks.com/fighting-ursa-car-for-sale-phishing-lure/) that a Russian threat actor they had been tracking was engaged in phishing campaigns targeting diplomats. The Fighting Ursa phishing campaign used a car for sale as a lure to distribute the [HeadLace](https://malpedia.caad.fkie.fraunhofer.de/details/win.headlace)backdoor malware. The campaign likely began as early as March 2024, and the threat actor has been [associated with Russian military intelligence](https://strapi.eurepoc.eu/uploads/Eu_Repo_C_APT_profile_APT_28_4856c0a0ac.pdf).

Unit 42 has observed other threat groups using similar tactics, posing as car sellers. In addition, the group [Fighting Ursa has been conducting campaigns](https://unit42.paloaltonetworks.com/russian-apt-fighting-ursa-exploits-cve-2023-233397/) leveraging a zero-day exploit in Microsoft Outlook (now known as CVE-2023-23397) targeting nation-states.

To help your team facilitate response, we are providing the [Unit 42 Threat Brief - Fighting URSA](https://cortex.marketplace.pan.dev/marketplace/details/Unit42_Threat_Brief__Fighting_Ursa/) content pack to help you automate the following:

* Collection, extraction, and enrichment of indicators
* Fetching threat actor-related detection rules
* Indicator-based threat hunting across your PANW products and SIEM solutions
* Mitigation actions where identified indicators can be blocked automatically or handled manually by the analyst
* Unit 42 recommendations for additional mitigation measures an analyst can take to reduce the likelihood of an impact

Sub-playbooks in this pack include:

* Threat hunting - generic playbook
* Block indicators - generic playbook
* Rapid Breach Response - set incident info
