COLUMBUS, Ohio — A new proof-of-concept shows that AI-generated malware can now bypass Microsoft Defender for Endpoint — albeit infrequently.
Researchers at Outflank, using reinforcement learning with an open-source model (Qwen 2.5), achieved a detection evasion rate of about 8% after just three months and ~$1.5K investment. That’s a significant jump from other models like Anthropic (< 1%) and DeepSeek (< 0.5%).
What This Means for Ohio Businesses Using Cloud Cover
- Advanced threats are evolving. The rise of AI–driven evasion techniques shows that attackers can now more reliably dodge endpoint detection.
- Multi-layered defense is critical. Relying solely on Microsoft Defender is no longer enough. Ohio SMBs should integrate Cloud Cover’s Managed Detection & Response (MDR) to detect stealthy threats that bypass traditional defenses.
- Stay ahead with AI-aware strategies. Cloud Cover helps businesses deploy AI-enhanced security— leveraging both advanced analytics and continuous monitoring to remediate threats evasive enough to slip past Defender.
Why This Isn’t a Tech Disaster— Yet
- Advanced threats are evolving. While an 8% success rate is notable, it’s not yet mass weaponized.
- Limited scale now. Requires specialist knowledge, GPU resources, and time— which sets a barrier for many threat actors.
- Microsoft will adapt. Defender updates are expected to counter new evasion techniques.
Still, the trajectory is clear— cybercriminals are learning fast.
For Ohio companies, the warning is immediate: don’t wait.

Maintaining Vigilance for your Business
Ohio's small businesses are particularly vulnerable to these AI-driven cyber threats. A survey found that over half of small business owners have been deceived by a deepfake image or video in the past year. Despite the growing risks, less than half of these businesses have the necessary cyber insurance coverage. Protect your business before it's too late.
