The average number of spear-phishing attacks rose to 53 per day in September, after a 12-month low in August. Spear phishing activity has returned to levels seen earlier in the summer, but is still down from the 12-month average of 85 attacks per day.
The .doc file type was the most common attachment type used in spear-phishing attacks, making up more than 52.9 percent of all attachments in September. At 4.8 percent, last month’s top attachment, .exe file types, dropped to fourth.
There were only four publically disclosed data breaches that took place within the month September, resulting in the exposure of 2.5 million identities. However, there were 14 additional data breaches reported in September that took place earlier in the year. The largest data breach reported in September actually took place in April, and resulted in the exposure of 56 million identities.
Ransomware continues to decline as 2014 progresses. However, crypto-style ransomware remains high, making up 38 percent of all ransomware detected in September.
There were 600 vulnerabilities disclosed in the month of September, the highest number so far in 2014 and second highest in last 12 months.
One in 2,041 emails was identified as a phishing attempt, compared with one in 1,587 for August. While at first glance this looks like a big drop, it results in only a 0.01 percentage point decrease in the overall phishing rate.

Symantec Intelligence Report :: SEPTEMBER 2014
Summary
Welcome to the September edition of the
Symantec Intelligence report. Symantec
Intelligence aims to provide the latest
analysis of cyber security threats, trends,
and insights concerning malware, spam, and
other potentially harmful business risks.
Symantec has established the most
comprehensive source of Internet threat
data in the world through the Symantec™
Global Intelligence Network, which is made
up of more than 41.5 million attack sensors
and records thousands of events per second.
This network monitors threat activity in
over 157 countries and territories through
a combination of Symantec products and
services such as Symantec DeepSight™
Threat Management System, Symantec™
Managed Security Services, Norton™
consumer products, and other third-party
data sources.
The average number of spear-phishing attacks rose to 53 per day
in September, after a 12-month low in August. Spear phishing
activity has returned to levels seen earlier in the summer, but is
still down from the 12-month average of 85 attacks per day.
The .doc file type was the most common attachment type used
in spear-phishing attacks, making up more than 52.9 percent of
all attachments in September. At 4.8 percent, last month’s top
attachment, .exe file types, dropped to fourth.
There were only four publically disclosed data breaches that
took place within the month September, resulting in the
exposure of 2.5 million identities. However, there were 14
additional data breaches reported in September that took
place earlier in the year. The largest data breach reported in
September actually took place in April, and resulted in the
exposure of 56 million identities.
Ransomware continues to decline as 2014 progresses. However,
crypto-style ransomware remains high, making up 38 percent of
all ransomware detected in September.
There were 600 vulnerabilities disclosed in the month of
September, the highest number so far in 2014 and second-high-est
in the last 12 months.
One in 2,041 emails was identified as a phishing attempt,
compared with one in 1,587 for August. While at first glance this
looks like a big drop, it results in only a 0.01 percentage point
decrease in the overall phishing rate.
We hope that you enjoy this month’s report and feel free to
contact us with any comments or feedback.

Methodology
This data is procured from the Norton Cybercrime Index (CCI). The Norton CCI is a statistical model
that measures the levels of threats, including malicious software, fraud, identity theft, spam,
phishing, and social engineering daily. The data breach section of the Norton CCI is derived from
data breaches that have been reported by legitimate media sources and have exposed personal
information.
In some cases a data breach is not publicly reported during the same month the incident occurred,
or an adjustment is made in the number of identities reportedly exposed. In these cases, the data in
the Norton CCI is updated. This causes fluctuations in the numbers reported for previous months
when a new report is released.

Track User Risks that spy on the individual using the device, collecting SMS
messages or phone call logs, tracking GPS coordinates, recording phone calls,
or gathering pictures and video taken with the device.
Steal Information This includes the collection of both device- and user-specific
data, such as device information, configuration data, or banking details.
Traditional Threats Threats that carry out traditional malware functions,
such as back doors and downloaders.
Recongure Device These types of risks attempt to elevate privileges
or simply modify various settings within the operating system.
Adware/Annoyance Mobile risks that display advertising or generally perform
actions to disrupt the user.
Send Content These risks will send text messages to premium SMS numbers,
ultimately appearing on the bill of the device’s owner. Other risks can be used to
send spam messages.

Social Media
Source: Symantec :: OCTOBER 2013 — SEPTEMBER 2014
Fake Offers These scams invite social network users to join a fake event or group
with incentives such as free gift cards. Joining often requires the user to share
credentials with the attacker or send a text to a premium rate number.
Manual Sharing Scams These rely on victims to actually do the work of sharing
the scam by presenting them with intriguing videos, fake offers or messages that they
share with their friends.
Likejacking Using fake “Like” buttons, attackers trick users into clicking website
buttons that install malware and may post updates on a user’s newsfeed, spreading the
attack.
Comment Jacking Similar to likejacking, this type of scam relies on users clicking
links that are added to comments by attackers. The links may lead to malware or survey
scams.
Fake App Users are invited to subscribe to an application that appears to be
integrated for use with a social network, but is not as described and may be used to
steal credentials or harvest other personal data.
