Report

SYMANTEC – 2012 From DC970’s first presentation in 2013…

31% of attacks targeted at businesses with fewer than 250 employees

32% of mobile threats are designed to steal information 69% of all email is spam 5291 new vulnerabilities discovered in 2012 (14.5/daily) One ‘watering hole’ attack infected 500 orgs in one day

DBIR 2015 - PATCHING 99.9% exploits were compromised more

than a year after the CVE released 2008 number was 71% E.g. MS08-067 = CVE-2008-4250

DBIR 2015, p19

DBIR 2015 – PHISHING 23% of recipients open

messages 11% click on attachments

First click: Average 82 seconds Overall: 50% of ‘clickers’ click

within one hour of the attack

DBIR 2015 p.12

DBIR 2015 - OTHER Mobile devices NOT a preferred vector in data breaches No ‘one size fits all’ approach to security

Size Industry Sector

DBIR 2015 – OOPS! Accidental C-I-A breach 30% - Misdelivery of sensitive info to incorrect recipients 17% - Published to public web server 12% - Improper disposal of info (personal, medical, etc…) Total of 60% attributed to sysadmin error 35% of systems are vulnerable to USB-initiated attacks

DBIR 2015 p51

E-COMMERCE WEB APP HACK Why?—Because the threat actor

made changes in the payment application code to capture and send data when processed.

Why?—They bypassed authentication to upload a backdoor to the server via Remote File Inclusion (RFI)

Why?—Because the JBoss version was outdated and vulnerable to a widely known attack.

Why?—Because the server software hadn’t been updated in

years. Why?—This is where it gets tricky. Because...they thought their

third-party vendor would do it? Because...they thought they had,

but failed to check implementation? Because...they had insufficient processes in place to manage their risk?
