> North Korea conducts state-sponsored cyber operations targeting financial institutions, digital currency exchanges, and critical infrastructure for revenue and espionage.

CISA, FBI, State Department, and Treasury issued a comprehensive advisory documenting North Korean cyber threats collectively referred to as HIDDEN COBRA. DPRK state-sponsored actors subordinate to entities like the Reconnaissance General Bureau conduct espionage, financial theft, and destructive operations globally.

DPRK cyber actors employ multiple revenue-generation tactics: cyber-enabled theft from financial institutions and digital currency exchanges (attempting up to $2 billion as of late 2019), extortion campaigns against third-party entities, and cryptojacking schemes mining digital currency on compromised machines. Specific attributed incidents include the 2014 Sony Pictures attack, the 2016 Bangladesh Bank heist ($81 million via SWIFT compromise), WannaCry 2.0 ransomware (May 2017, affecting 150+ countries), the FASTCash ATM fraud campaign (since late 2016, stealing tens of millions across 30+ countries), and a 2018 digital currency exchange hack ($250 million stolen).

Defenders should implement network segmentation, maintain data backups, conduct phishing awareness training, develop incident response plans, monitor for DPRK malware indicators via CISA HIDDEN COBRA resources, and report suspected incidents to law enforcement immediately to maximize recovery chances.

## Mentioned in this report

- Threat actors: DPRK, Lazarus Group
- Malware: Cryptojacking malware, FastCash, WannaCry 2.0
- Campaigns: FASTCash, HIDDEN COBRA

## Detection guidance (public sample)

### BITS Job Created via Bitsadmin to Download from Remote URL

ATT&CK: T1197

bitsadmin.exe /transfer or /addfile pulling content from an HTTP(S) URL, a living-off-the-land download and persistence method used by many intrusion sets. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.

```yaml
title: BITS Job Created via Bitsadmin to Download from Remote URL
description: Detects bitsadmin.exe creating a transfer job that pulls a file from
  an http(s) URL. Abuse of BITS jobs for payload download or persistence maps to T1197.
  The rule matches the flag and URL pattern, not specific file names or hosts.

### Run Key Persistence Pointing to User-Writable Directory

ATT&CK: T1547.001

A registry Run/RunOnce value is set to launch a binary from AppData, Temp, ProgramData or Users\Public, a common malware persistence pattern. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.

```yaml
title: Run Key Persistence Pointing to User-Writable Directory
description: Detects creation or modification of a CurrentVersion Run or RunOnce registry
  value whose data points to a user-writable location such as AppData, Temp, ProgramData
  or Users\Public. Typical of implant persistence (T1547.001). Matches the key and
  path pattern, not specific value names.
