Grab your beverage of choice ☕, because there's a LOT to recap from the last 24 hours. Check it out here 👉 opalsec.io/daily-news-update-f

There's a lot to digest, so if you're running between meetings or scoffing down a quick lunch before the next - here's the TL;DR on the key points:

🚨 Urgent Ivanti Patch Alert: A critical RCE zero-day is being actively exploited by suspected China-nexus group UNC5221, who are deploying new malware (TRAILBLAZE, BRUSHFIRE).

🌐 Fast Flux is Back in the Spotlight: Five Eyes agencies dropped a joint advisory on the increased use of this evasion technique by sophisticated actors (ransomware gangs, state-sponsored groups). It makes tracking C2s & phishing sites a real headache by rapidly changing IPs/nameservers.

🔗 GitHub Supply Chain Attack Deep Dive: Remember that complex attack targeting Coinbase via GitHub Actions? Unit 42 traced its origin back to a single leaked SpotBugs Personal Access Token from late 2024! A huge reminder about token hygiene, the risks of mutable tags, and those cascading dependency threats. Rotate secrets if you use SpotBugs, Reviewdog, or tj-actions!

🤔 Oracle's Cloud Breach Saga Continues...: Oracle reportedly admitted a breach to customers, framing it as a "legacy" (pre-2017) environment issue, yet, the actor leaked data allegedly from late 2024/2025. The focus on "Oracle Cloud Classic" vs. OCI feels like damage control over transparency. As I put it in the blog, their handling doesn't exactly inspire confidence – trust is earned, folks.

🔄 Rethinking Disaster Recovery in the Ransomware Era: DR is way more than just backups now. With hybrid environments sprawling and ransomware the top threat, recovery is Incident Response (detect, isolate, wipe, reinstall, restore). Homogeneity might simplify recovery, but beware of single points of failure (hello, CrowdStrike outage!).

📡 Mass Scanning Alert: Seeing increased probes against Juniper devices (looking for default 't128' creds - change 'em!) and Palo Alto GlobalProtect portals. Motives are unclear – could be recon, botnet building, or sniffing for vulnerabilities. Keep those edge devices patched and hardened!

🇺🇦 New Malware 'Wrecksteel' Hits Ukraine: CERT-UA warns of a new espionage malware targeting state agencies and critical infrastructure via phishing. Deployed by UAC-0219, Wrecksteel exfiltrates documents and takes screenshots.

⚖️ INC Ransomware Claims State Bar of Texas: The second-largest US bar association confirmed a data breach after INC ransomware listed them on their leak site.

Stay informed, stay vigilant, and let me know your thoughts in the comments! What's catching your eye this week?

Opalsec · Daily News Update: Friday, April 4, 2025 (Australia/Melbourne)Chinese group exploiting Ivanti RCE bug since mid-March to drop web shells; DNS Fast Flux increasingly used by cyber crims & nation-states; GitHub Supply Chain attack traced to leaked Access Token in a CI workflow; Oracle says breach is of legacy system - receipts show otherwise.
