Full Report
Someone in the office was discussing Microsoft’s recent horrible foray into the anti-virus market. Apparently an online source held one-care as faring worse than a simple man with a perl script. A quick scan shows that they have indeed faired pretty poorly in independent tests: “(BBC News) OneCare was the only failure among 17 anti-virus programs tested by the AV Comparatives organisation.” Now the obvious question was: How could Microsoft possibly get it so wrong? (Cue the drum roll, bring out your tin foil hats)
Analysis Summary
# Microsoft OneCare Anti-Virus Performance Failure
## Key Points
- Microsoft's anti-virus product, OneCare, performed remarkably poorly in independent testing against established competitors.
- Specifically, AV Comparatives testing identified OneCare as the "only failure among 17 anti-virus programs tested."
- The article suggests this failure might be intentional or highly significant, contrasting with the expectation of superior performance from a major technology vendor like Microsoft trying to enter the AV market.
- The poor result is humorously contrasted with the efficacy of "a simple man with a perl script."
## Threat Actors
- No specific malicious threat actors (e.g., criminal groups or APTs) or traditional cyber adversaries are discussed in relation to this performance failure.
- The focus is on Microsoft as the underperforming entity being analyzed by security professionals.
## TTPs
- Not applicable. The article describes a performance analysis of security software, not a cyber attack technique.
- The underlying context, however, involves Microsoft's previous security actions, such as the introduction of Kernel patch protection (PatchGuard), which restricted third-party kernel hooking by competitors.
## Affected Systems
- Microsoft OneCare (anti-virus product).
- Independent anti-virus testing organizations (AV Comparatives).
## Mitigations
- The context implies that organizations should be aware of the performance metrics of their chosen security products.
- The scenario suggests skepticism about vendor claims, advocating for reliance on independent verification (like AV tests).
## Conclusion
The primary intelligence nugget here is the documented, poor comparative performance of Microsoft OneCare against industry peers in independent antivirus testing. The analysis speculates this failure may serve as a strategic "sacrificial lamb" to potentially mitigate backlash from security competitors regarding Microsoft's control over Windows internals (e.g., PatchGuard), suggesting a potential strategic decision rather than a simple engineering failure. Security teams should exercise caution and rely on verified third-party testing when evaluating security stacks, including those from platform vendors.
