Why now
- Multiple outlets are flagging active exploitation in the current cycle
- Reports emphasize continued attacker success despite an older patch
- Phishing and commodity malware outcomes keep the issue operationally relevant
Why it matters
- Patch availability doesn’t prevent compromise when endpoints remain unpatched
- Phishing-led exploitation can quickly translate into RAT/infostealer deployment
- Broad actor mix suggests a repeatable intrusion path for multiple adversaries
