Which of the following types of application attacks would be used to identify malware causing
security breaches that have NOT yet been identified by any trusted sources?

A.
Zero-day

B.
LDAP injection

C.
XML injection

D.
Directory traversal

Explanation:

The security breaches have NOT yet been identified. This is zero day vulnerability.
A zero day vulnerability refers to a hole in software that is unknown to the vendor. This security
hole is then exploited by hackers before the vendor becomes aware and hurries to fix it—this
exploit is called a zero day attack. Uses of zero day attacks can include infiltrating malware,
spyware or allowing unwanted access to user information. The term “zero day” refers to the
unknown nature of the hole to those outside of the hackers, specifically, the developers. Once the
vulnerability becomes known, a race begins for the developer, who must protect users.
