Provided are a system and method for detecting a malicious script. The system includes a script decomposition module for decomposing a web page into scripts, a static analysis module for statically analyzing the decomposed scripts in the form of a document file, a dynamic analysis module for dynamically executing and analyzing the decomposed scripts, and a comparison module for comparing an analysis result of the static analysis module and an analysis result of the dynamic analysis module to determine whether the decomposed scripts are malicious scripts. The system and method can recognize a hidden dangerous hypertext markup language (HTML) tag irrespective of an obfuscation technique for hiding a malicious script in a web page and thus can cope with an unknown obfuscation technique.

Provided are a rotational PCR apparatus, a PCR chip for the same and a rotational PCR method using the same. The disclosed rotational PCR apparatus includes: a PCR chip where PCR is performed; a rotating means connected to the PCR chip and rotating the PCR chip; and a temperature zone forming means spaced apart from the PCR chip, capable of applying thermal energy to the PCR chip and allowing the rotating PCR chip to pass through different temperature zones. The rotational PCR apparatus and method allow performance of PCR with wanted temperature condition and cycles by rotating the chip containing the target substance. Accordingly, a high-efficiency PCR process may be accomplished at low cost. Further, since the target substance can be effectively separated and purified utilizing the centrifugal force resulting from the rotating platform, separation and purification may be achieved economically without requiring additional equipments.
