Cloud Sync Applications Cause Malware to Spread Across Computers

One fresh report shows how cloud application use rapidly expanding isn't merely disseminating malicious software quicker than before, but proliferating ransomware encryption impact too among end-users. This happens despite the secondary infected user not really downloading the malware himself.
