• → Type confusion triggered via FileReference constructor called from within TextFormat constructor — monitor for SWF files invoking flash.net.FileReference with a crafted object whose __proto__.__constructor__ is set to TextFormat and then overridden to flash.net.FileReference ↗
• → Look for SWF ActionScript patterns where an object's __proto__.__constructor__ is dynamically switched between TextFormat and flash.net.FileReference within valueOf/toString callbacks, a hallmark of this exploit's confusion chain ↗
• → Detect use of cancel.call() on a non-FileReference object as an anomalous invocation pattern associated with this exploit PoC ↗

• · CVE-2015-5558 is one of multiple distinct type-confusion vulnerabilities (alongside CVE-2015-5554, CVE-2015-5555, CVE-2015-5562) patched in APSB15-19; ensure detections differentiate the FileReference/TextFormat confusion chain specific to 5558 from the other variants ↗
