CSO examines the weaponization and delivery aspect of an APT-based campaign. This is where the serious work begins, and marks the first hurdle an attacker needs to overcome. Generic attacks rely on volume, so attackers will send the same link or the same malware hundreds, or even thousands of times. A targeted attack will use multiple links, various types of malware, and keep numbers low, which allows them to operate in silence. Generic campaigns are noisy, thus easily detected and stopped, which is why volume is so important.”]
