@AlienVault Ransomware 101

• Malicious payload restricts access to files and demands ransom paid to recover them • First known example (“AIDS/PC Cyborg” trojan) seen in 1989 • Ransomware sightings picked back up in 2005 (Gpcode(.AG, .AK), Archiveus, etc. • Using more and more complicated encryption schemes • 2013 – CryptoLocker puts ransomware “on the map” • 10/15/2013 – 12/18/2013 – estimated $27m extorted • 6/2014 - ZeuS botnet eventually seized by US DOJ • Still seeing variants today (CL v2.0, CryptoLocker.F, TorrentLocker…) Ransomware in 4 Easy Steps

1. Malware delivered via email or drive-by 2. File executes & compromises system 3. Trojan connects with C&C server 4. Encryption & notification of user begins Mitigation

Especially with today’s variants, you will not be able to decrypt your data via conventional means. Here are some steps to take to thwart these attacks: • Backup your data… OFTEN • Educate your users about malicious emails/attachments • Keep operating systems and applications updated • Keep endpoint protection up to date

Firewalls/Antivirus are not enough

• Firewalls are usually not the target – too difficult to effectively penetrate • Endpoints are the target, usually via email, url redirects, misc malicious files, etc. • With 160,000 new malware samples seen every day, antivirus apps will not find every threat • Needs to be bolstered by regular and comprehensive monitoring.
