If you're short on time, here's a quick rundown of the key stories:
Australian Pension Funds Under Attack: A significant credential stuffing campaign hit multiple Aussie superannuation funds (Australian Super, REST, Hostplus, Insignia, ART) over the March 29-30 weekend. Attackers used stolen creds, likely targeting web portals and mobile apps, accessing accounts and unfortunately stealing funds in some cases (reports mention ~AU$500k from four Australian Super members alone). ASFA is coordinating the response. A stark reminder about password reuse and MFA effectiveness, especially during off-hours!
Shake-up at NSA/Cyber Command: Big news out of the US – Gen. Timothy Haugh has been fired from his dual-hat role leading the NSA and USCYBERCOM after just over a year. Deputy Director Wendy Noble is also reportedly out. Reasons are murky, but speculation points towards political motivations (linked to Laura Loomer's visit with President Trump). This raises questions about stability, the ongoing 'Cybercom 2.0' review, and the future of the dual-hat structure, especially with ongoing nation-state threats.
Incident Response Speed vs. Backups: An interesting debate highlighted recently – while backups are vital for recovery, is rapid IR potentially even more critical? It’s a tough balancing act: contain fast (risking tipping off attackers/losing evidence) or investigate thoroughly while the breach continues? Emphasises the need for skilled responders and adequate tooling, not just relying on backups as a silver bullet.
Critical RCE in Apache Parquet (CVE-2025-30065): Heads up, data folks! A CVSS 10.0 RCE vulnerability has been found in the widely used Apache Parquet columnar storage format (up to v1.15.0). Given its use in Hadoop, AWS, Azure, GCP, and by major tech companies, the potential impact is huge. Patch to version 1.15.1 ASAP!
Pentagon Probes Defense Secretary's Signal Use: The DoD's Inspector General is investigating Defense Secretary Pete Hegseth's use of Signal for official business. This follows a report where a journalist was accidentally added to a Signal chat discussing sensitive airstrike details (targets, timing). Raises concerns about classified info on unclassified apps, need-to-know, and record-keeping compliance.

What are your biggest takeaways from this week's news? Let's discuss below!
Oracle finally admits to a major data breach—after being sued for hiding it.
Extortion attempt reported
Plaintiffs demand better security & transparency
, because there's a LOT to recap from the last 24 hours. Check it out here 
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. 
We hope you are as excited as we are for the release of FIRSTCON25's agenda
Drum Roll!
