Ransomware Takes Open-Source Path, Encrypts With GNU Privacy Guard

McAfee Labs has recently observed a new variant of ransomware that relies on the open-source program GNU Privacy Guard (GnuPG) to encrypt data. GnuPG is a hybrid-encryption software program that uses a combination of conventional symmetric-key cryptography for speed and public-key cryptography to ease the secure key exchange. Although ransomware using GnuPG to encrypt files is not unique, it is uncommon.
