Threat landscape: Our new reality
• More and more organizations are finding themselves in the crosshairs of various bad actors for a variety of reasons.
• The number of organizations experiencing high profile breaches is unprecedented.
• The “security arms race” cannot continue indefinitely as the economics of securing your organization is stacked so heavily in favor of those launching attacks that incremental security investments are seen as impractical.
84%of organizations breached
had evidence of the breach in their log files…

“There are two types of
companies that use computers.
Victims of crime that know they
are victims of crime and victims
of crime that don’t have a clue
yet.”
“How would you change your
strategy if you knew for certain
that you were going to be
compromised?”

Prevention is Elusive
Prevent Detect & Respond
The basics are in place for most
companies…but this alone is a ‘proven’ failed
strategy.
New capabilities to develop
Get (Very) good at detection & response
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
