Mimecast, which provides email management systems, updates that the hacker was able to hack into the company’s systems and access customer information.
According to the company, the hacker was able to gain access to a certificate used to identify Mimecast services located on Microsoft’s server.
The company also states that all customers who may have been harmed have been updated and it also asks all customers of the company to replace the existing certificate in their possession with a new certificate issued by the company.
The breach was identified by Microsoft, which updated Mimecast that an unidentified source accessed the company’s servers.
According to DZNet: Mimecast says hackers abused one of its certificates to access Microsoft accounts.
Mimecast, a provider of email management software, said learned of the security incident from Microsoft.

Executives and Celebrities Are Prime Targets for Social Engineering Attacks
🚨 Executives and Celebrities Under Targeted Attacks
💡 Hackers are exploiting public data and social media to craft highly convincing schemes.
⚠️ Personalized social engineering attacks manipulate psychology – urgency, flattery, or fear – to bypass standard security.
📊 Even top-tier executives with robust IT defenses are vulnerable because human behavior remains the weak link.
🔍 Every interaction, post, or appearance can be mined to create targeted attacks that compromise individuals and organizations alike.
🔥 Mitigation requires proactive social engineering simulations and continuous employee training.
👥 AUMINT Trident simulates real-world attacks, tracks responses, and strengthens your human firewall before breaches happen.

☁️🔍 Free Cloud Misconfiguration Scanners You’ll Wish You Tried Earlier ☁️🔍
Cloud misconfigurations remain the #1 cause of breaches in 2025 – and the worst part is, most could have been avoided with the right tools. Here are some free scanners that every CISO should have in their arsenal:
1️⃣ ScoutSuite – Multi-cloud security auditing tool by NCC Group.
🔗 https://github.com/nccgroup/ScoutSuite
2️⃣ Prowler – AWS, Azure, and GCP security best practices scanner.
🔗 https://github.com/prowler-cloud/prowler
3️⃣ CloudSploit by Aqua – Continuous configuration monitoring for major cloud providers.
🔗 https://github.com/aquasecurity/cloudsploit
4️⃣ Checkov – Policy-as-code scanner for IaC (Terraform, Kubernetes, CloudFormation).
🔗 https://github.com/bridgecrewio/checkov
5️⃣ Cloud Custodian – Rules engine for governance and compliance enforcement.
🔗 https://github.com/cloud-custodian/cloud-custodian
⚡These tools highlight risky IAM roles, exposed buckets, insecure defaults, and weak policies – the same gaps attackers exploit.
At AUMINT.io, we look at the other side of the coin – simulating how attackers exploit the human misconfigurations through phishing, vishing, and social engineering. Because even a perfectly hardened cloud is vulnerable if an employee gives access away.

PipeMagic Malware Exposes How Easily Critical Systems Can Be Hijacked
🚨 PipeMagic Malware Threatens Critical Industrial Systems
💡 PipeMagic targets pipeline management systems, manipulating valves, monitoring operations, and hiding in plain sight.
⚠️ What makes it dangerous? It combines technological exploits with human errors, bypassing traditional IT defenses to compromise industrial operations.
📊 Most organizations focus on IT security while leaving operational technology exposed. Attackers know OT networks are the true leverage points.
🔍 Employee actions are just as critical – executing one malicious command can give attackers full operational control.
🔥 Mitigation requires a dual approach: strengthen OT defenses and train employees to spot sophisticated attacks through recurring, realistic simulations.
👥 AUMINT Trident provides these simulations, tracking vulnerabilities and turning employees into active defenders before attacks succeed.
