However, Kol Husin Jazri, director of the National ICT Security and Emergency Response Team (Niser), said in an e-mail interview that the attacks weren’t platform specific but were targeted at virtual webhosts.
MyCERT is a unit of Niser and is responsible for tracking and logging security incidents, as well as analysing major security incidents and trends.
Virtual hosts are multiple websites hosted on a single machine.
"A few of this virtual hosts were target¬ed resulting in between 20 to 100 web¬sites being defaced at any one time," Husin said. Intelligence and reconnaissance activities are involved before launching the attacks, Husin said.
Husin said the recent attacks indicates attackers have taken due diligence before executing their strategies. "Intelligence and reconnaissance activities are involved before launching the attacks," he said.
MyCERT's analysis of the recent attacks showed that it was done via PHP scripting vulnerability. (PHP is web scripting language).
Husin said this involves modifying computer program scripts to ensure validation of input.
"These vulnerabilities are exploited to allow entry to access certain restricted locations within the host," Husin said. He added that in some cases, these vulnerability exploits even open up arbitrary Net connections and turn some PHP scripts into proxies and open mail relays.
MyCERT has already pro¬vided an alert on the recent attacks and encourages victims to submit the audit trails to MyCERT through the MyCERT website for further analysis.
