TL;DR

Major GitLab breach at Red Hat’s consulting instance is confirmed — treat any engagement artifacts or CERs as potentially exposed and rotate related secrets now.
Elliptic reports North Korea–linked actors have stolen north of $2B in crypto so far in 2025 — exchanges and custody teams should harden signing workflows and freeze suspicious flows.
Ransomware activity remains elevated and tactically evolving (more exfiltration and AI-assisted ops) — follow the quick containment checklist below.
VirusTotal simplified access and added a Contributor track — review your ingestion and contributor strategy if you rely on VT/GTI feeds.

Top headlines this week

1) Red Hat — GitLab consulting instance breached

Red Hat has acknowledged unauthorized access to an internal GitLab instance used by its Consulting team; the company isolated the system and opened an investigation. Public reporting and actor claims indicate a large dataset was exfiltrated (reports cite ~570GB and tens of thousands of projects in actor claims), including Customer Engagement Reports and project artifacts — treat any consulting artifacts or referenced credentials as potentially exposed and act accordingly.

2) $2B+ in crypto stolen — North Korea–linked activity

Blockchain analysis firm Elliptic reports North Korea–linked groups have stolen more than $2 billion in crypto during 2025 so far, driven by a small number of very large heists and many smaller operations. Exchange, custody and treasury teams should assume aggressive laundering and layering workflows and coordinate with blockchain analysts and law enforcement for tracing.

3) Ransomware — spike & tactic shifts

Vendor telemetry and quarterly research (Check Point, Kaspersky and others) show continuing ransomware pressure: more exfiltration-first playbooks, leak-site activity, and attackers experimenting with AI to scale social engineering and reconnaissance. Prioritize backups, credentials rotation and high-signal hunts (detailed below).

4) VirusTotal overhaul — simpler tiers + Contributor model

VirusTotal announced simplified access tiers and a Contributor track intended to reward engine partners and high-volume telemetry contributors with priority feeds and early feature access. If your SOC or intelligence team ingests VT/GTI feeds, review quota/tier changes and contributor options to avoid unexpected disruption.

Hunting recipes & SIEM queries

Tune to your platform — these are defensive, high-signal hunts.

# Example (Splunk): suspicious CI pushes and release activity
index=ci source="gitlab" OR source="github_actions" event=push
| stats count by user, repo, branch
| where branch=="release" AND count > 5

# Example (pseudo-SQL): large outbound egress
SELECT src_host, SUM(bytes_sent) AS outbound_bytes
FROM netflow
WHERE direction = 'egress' AND event_time > NOW() - INTERVAL '24' HOUR
GROUP BY src_host
HAVING outbound_bytes > 100000000;

# Example: detect unusual signing events in key management logs
SELECT signer, key_id, COUNT(*) AS uses
FROM signing_logs
WHERE event_time > NOW() - INTERVAL '7' DAY
GROUP BY signer, key_id
HAVING uses > expected_threshold;

Patches & advisories to watch (this week)

Vendor advisories on the Red Hat GitLab incident — follow Red Hat for the official IOCs and remediation guidance.
Elliptic and industry posts on crypto theft patterns — exchanges should review exchange/bridge advisories and freezing guidance.
Ransomware trend updates from Check Point and Kaspersky — check their feeds for fresh indicators and sector-specific advisories.
VirusTotal/GTI changelog — if you rely on VT feeds, check your ingestion connectors and contributor documentation.

What to tell your customers / users

We detected a major industry incident this week involving a vendor consulting repository. If you use third-party consultants, we’ve proactively rotated affected keys (where applicable) and are monitoring for suspicious activity. Please report any unexpected account activity and follow our usual guidance: enable MFA, use hardware-backed second factors, and do not click links in unexpected messages.
