The biggest bogeyman in security is the advanced persistent threat (APT) – well funded, smart and motivated. Kaspersky’s predictions for 2016 claims that APTs will go deeper and undercover – less traceable and harder to detect.
To be clear, the threat will remain but the move is to memory or fileless non-persistent malware. By repurposing existing malware attackers can appear less advanced than in the past to increase stealth.
It’s a concern from the IoT perspective because critical infrastructure is a target from cyber terrorism and a big part of M2M and IoT. APTs becoming more sophisticated by appearing less so is a daunting concept.
