Palo Alto Intent to Bolster AI Security with Koi
Palo Alto Networks announced its intent to acquire Koi, an emerging security firm focused on Agentic Endpoint Security. Koi develops technology designed to secure the “Agentic Endpoint” — the expanding AI-native attack surface across modern workplaces. The acquisition aims to close a critical security gap as AI agents and tools, which operate with deep access to data and permissions but often outside traditional monitoring frameworks, become increasingly embedded in enterprise environments. Financial terms were not disclosed.

North Korean PurpleBravo Targets Developers
PurpleBravo, tracked by Recorded Future’s Insikt Group, targeted 3,136 individual IP addresses across 20 victim organizations in AI, cryptocurrency, financial services, and software development sectors in Europe, South Asia, the Middle East, and Central America. The group used fake LinkedIn personas and malicious GitHub repositories to deliver BeaverTail (a JavaScript infostealer) and GolangGhost (a Go-based backdoor). Candidates approached with fake job offers were found taking coding assessments on company-issued devices, effectively compromising their employers in the process.

Notepad++ Supply Chain Attack: A Six-Month Story
Notepad++’s update infrastructure was compromised through a hosting provider-level incident that ran silently for nearly six months. Attackers retained access to internal services well after initial intrusion, and users who updated during that window had no visible indication anything was wrong. The post highlights this as a case study in long dwell-time supply chain attacks and the dangers of trusting software update pipelines without verification mechanisms.

Betterment Suffers a Data Breach
Automated investment platform Betterment disclosed a breach affecting approximately 1.4 million customers following a sophisticated social engineering attack. Attackers gained access to third-party marketing and operational tools and used them to send fraudulent emails promoting a fake cryptocurrency scheme. The post notes that while core financial infrastructure remained uncompromised, the misuse of peripheral systems to reach customers underlines how third-party tool access is a growing attack vector.

PayPal Data Breach – Six Months of Silent Exposure
PayPal’s Working Capital loan application suffered a breach caused by an internal software coding error — not an external hack — which left sensitive PII including Social Security numbers exposed for roughly six months. The post emphasizes how internal software defects can be as damaging as external intrusions, and critiques the delayed disclosure timeline. PayPal responded by rolling back the faulty code, resetting affected passwords, and offering two years of free credit monitoring.
