Well-funded and highly motivated threat actors have evolved their
techniques from generic, opportunistic, and scattershot attacks to an
approach that is targeted, resilient, and evasive.
The findings, based on data gleaned from FireEye Dynamic Threat Intelligence (DTI), are alarming:
- More than 1.5 APTs per hour were detected
- 40 APT variants were identified
- More than half of all callbacks from Israeli targets appear to contact first-tier CnC nodes based in the U.S.
- The volume of detected malware quadrupled between January and December
- Defense/airlines, government, and financial services were the most-targeted verticals
Figure 1 shows the volume of cyber attacks aimed at Israeli systems over the last year.

April and September 2013 Surges
Some spikes in activity can be tied to external events:
- April/May 2013: This surge possibly stemmed from an Anonymous campaign (#op-Israel) launched against Israel in April. And a group supporting embattled Syrian president Bashar al-Assad reportedly attacked Israeli infrastructure in May in an attempt to retaliate against a Israeli bombing in Syria.
- September/October 2013: The Jewish New Year
holiday lasted through September, giving threat actors an opening to
infiltrate organizations during worker vacations.
APTs are an everyday reality
Figure 2 shows the types of attacks against Israeli systems in 2013 by category.
Figure 2: Detected cyber attacks, by type
Common viruses remain the most common form of attack. But APTs are second at a whopping 25 percent of all attacks.
(Although backdoors, Trojans, info stealers, malware binaries, and
malicious URLs are all used in APT attacks, they also enable a wide
range of broader attacks, such as cyber crime. The APT category in
Figure 2 includes only advanced targeted attacks, even if they involved
components listed in other categories.)
