 # Ukraine-Cyber-Operations Curated Intelligence is working with analysts from around the world to provide useful information to organisations in Ukraine looking for additional free threat intelligence. Slava Ukraini. Glory to Ukraine. ([Blog](https://www.curatedintel.org/2021/08/welcome.html) | [Twitter](https://twitter.com/CuratedIntel) | [LinkedIn](https://www.linkedin.com/company/curatedintelligence/))   ### Analyst Comments: - 2022-02-25 - Creation of the initial repository to help organisations in Ukraine - Added [Threat Reports](https://github.com/curated-intel/Ukraine-Cyber-Operations#threat-reports) section - Added [Vendor Support](https://github.com/curated-intel/Ukraine-Cyber-Operations#vendor-support) section - 2022-02-26 - Additional resources, chronologically ordered (h/t Orange-CD) - Added [Vetted OSINT Sources](https://github.com/curated-intel/Ukraine-Cyber-Operations#vetted-osint-sources) section - Added [Miscellaneous Resources](https://github.com/curated-intel/Ukraine-Cyber-Operations#miscellaneous-resources) section - 2022-02-27 - Additional threat reports have been added - Added [Data Brokers](https://github.com/curated-intel/Ukraine-Cyber-Operations/blob/main/README.md#data-brokers) section - Added [Access Brokers](https://github.com/curated-intel/Ukraine-Cyber-Operations/blob/main/README.md#access-brokers) section - 2022-02-28 - Added Russian Cyber Operations Against Ukraine Timeline by ETAC - Added Vetted and Contextualized [Indicators of Compromise (IOCs)](https://github.com/curated-intel/Ukraine-Cyber-Operations/blob/main/ETAC_Vetted_UkraineRussiaWar_IOCs.csv) by ETAC - 2022-03-01 - Additional threat reports and resources have been added - 2022-03-02 - Additional [Indicators of Compromise (IOCs)](https://github.com/curated-intel/Ukraine-Cyber-Operations/blob/main/ETAC_Vetted_UkraineRussiaWar_IOCs.csv#L2011) have been added - Added vetted [YARA rule collection](https://github.com/curated-intel/Ukraine-Cyber-Operations/tree/main/yara) from the Threat Reports by ETAC - Added loosely-vetted [IOC Threat Hunt Feeds](https://github.com/curated-intel/Ukraine-Cyber-Operations/tree/main/KPMG-Egyde_Ukraine-Crisis_Feeds/MISP-CSV_MediumConfidence_Filtered) by KPMG-Egyde CTI (h/t [0xDISREL](https://twitter.com/0xDISREL)) - IOCs shared by these feeds are `LOW-TO-MEDIUM CONFIDENCE` we strongly recommend NOT adding them to a blocklist - These could potentially be used for `THREAT HUNTING` and could be added to a `WATCHLIST` - IOCs are generated in `MISP COMPATIBLE` CSV format - 2022-03-03 - Additional threat reports and vendor support resources have been added - Updated [Log4Shell IOC Threat Hunt Feeds](https://github.com/curated-intel/Log4Shell-IOCs/tree/main/KPMG_Log4Shell_Feeds) by KPMG-Egyde CTI; not directly related to Ukraine, but still a widespread vulnerability. - Added diagram of Russia-Ukraine Cyberwar Participants 2022 by ETAC - Additional [Indicators of Compromise (IOCs)](https://github.com/curated-intel/Ukraine-Cyber-Operations/blob/main/ETAC_Vetted_UkraineRussiaWar_IOCs.csv#L2042) have been added #### `Threat Reports` | Date | Source | Threat(s) | URL | | --- | --- | --- | --- | | 14 JAN | SSU Ukraine | Website Defacements | [ssu.gov.ua](https://ssu.gov.ua/novyny/sbu-rozsliduie-prychetnist-rosiiskykh-spetssluzhb-do-sohodnishnoi-kiberataky-na-orhany-derzhavnoi-vlady-ukrainy)| | 15 JAN | Microsoft | WhisperGate wiper (DEV-0586) | [microsoft.com](https://www.microsoft.com/security/blog/2022/01/15/destructive-malware-targeting-ukrainian-organizations/) | | 19 JAN | Elastic | WhisperGate wiper (Operation BleedingBear) | [elastic.github.io](https://elastic.github.io/security-research/malware/2022/01/01.operation-bleeding-bear/article/) | | 31 JAN | Symantec | Gamaredon/Shuckworm/PrimitiveBear (FSB) | [symantec-enterprise-blogs.security.com](https://symantec-enterprise-blogs.security.com/blogs/threat-intelligence/shuckworm-gamaredon-espionage-ukraine) | | 2 FEB | RaidForums | Access broker "GodLevel" offering Ukrainain algricultural exchange | RaidForums [not linked] | | 2 FEB | CERT-UA | UAC-0056 using SaintBot and OutSteel malware | [cert.gov.ua](https://cert.gov.ua/article/18419) | | 3 FEB | PAN Unit42 | Gamaredon/Shuckworm/PrimitiveBear (FSB) | [unit42.paloaltonetworks.com](https://unit42.paloaltonetworks.com/gamaredon-primitive-bear-ukraine-update-2021/) | | 4 FEB | Microsoft | Gamaredon/Shuckworm/PrimitiveBear (FSB) | [microsoft.com](https://www.microsoft.com/security/blog/2022/02/04/actinium-targets-ukrainian-organizations/) | | 8 FEB | NSFOCUS | Lorec53 (aka UAC-0056, EmberBear, BleedingBear) | [nsfocusglobal.com](https://nsfocusglobal.com/apt-retrospection-lorec53-an-active-russian-hack-group-launched-phishing-attacks-against-georgian-government) | | 15 FEB | CERT-UA | DDoS attacks against the name server of government websites as well as Oschadbank (State Savings Bank) & Privatbank (largest commercial bank).
