Abstract

“ In monitoring the ransomware TorrentLocker, we noticed a new development in its arrival vector. In previous entries, we noted that a particular wave of the crypto-ransomware was using spammed messages that were designed to evade spam filters. Our research now shows that TorrentLocker malware are using emails that are designed to pass spam filters and also collect information.
