Trend Micro has published their report on Luckycat APT campaign.
Advanced persistent threat (APT) usually refers to a group with both the capability and the intent to persistently and effectively target a specific entity.
Advanced – Operators behind the threat have a full spectrum of intelligence-gathering techniques at their disposal. Persistent – Operators give priority to a specific task, rather than opportunistically seeking information for financial or other gain. Threat – APTs are a threat because they have both capability and intent.
In the examples of the report, the machines were compromised by exploiting vulnerabilities in Adobe Reader and in Microsoft Office.
