Summary

Welcome to the June 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 largest data breach reported in June resulted in the exposure up 1.3 million identities. This seems like a small number when compared to the 145 million exposed in the largest breach of May. However, while reported in June, this breach also took place during the month of May. This brings the total number of identities exposed in May to over 147 million, which is the second-worst month for data breaches in the last 12 months.

There was an average of 88 spear-phishing attacks per day in June. This appears to be a return of spear-phishing levels seen in the months of March and April, after the average per day dropped in May.

A relatively new OSX threat by the name of OSX.Stealbit.B topped our list of OSX malware, responsible for 25.7 percent of OSX threat found on OSX systems. This threat looks for specific bitcoin-related software on OSX computers and will attempt to modify the programs in order to steal bitcoins.

The number of Android variants per family reached the lowest levels seen in the last twelve months. While there was not a significant change in the number of families discovered in June, this may indicate that attackers have had more success with their current set of threats, reducing their need to create multiple variants.

June was a quiet month for vulnerabilities, where (only) 438 were reported—tying the lowest number reported in the last 12 months. There were no zero day vulnerabilities disclosed during the month.

We hope that you enjoy this month’s report and feel free to contact us with any comments or feedback.

MethodologyThis 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.

Mobile Threat ClassificationsSource: Symantec :: JULY 2013 — JUNE 2014

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.

Recon�gure 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

Social MediaSource: Symantec :: JULY 2013 — JUNE 2014

70%

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.
