Welcome to the October 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.
This month we saw one of the largest data breaches in a number of years, where 150 million identities were exposed due to this one breach. This has more than doubled the number of identities exposed so far this year, when compared to our previous numbers through September.
October also saw an increase in the number of targeted attacks. These numbers are up fivefold compared to September, and even surpassing previous Octobers in 2011 and 2012, though still much lower than their peaks this summer.
When comparing the size of the targeted organizations, we see that a majority of attack attempts are against large corporations with 2500-plus employees. However, when looking at the first time an organization registers a targeted attack attempt, this number is much higher for organizations with fewer than 250 employees. This indicates that more new attack attempts are being made across the smaller business spectrum, though larger organizations are more likely to be targeted continuously.
Also, the total number of mobile vulnerabilities disclosed dropped significantly in October. September’s number was unusually high due to the release of a major update to a popular mobile operating system, which addressed a number of vulnerabilities in the software.
In other news, fake offerings continue to dominate Social Media attacks, disclosed vulnerability numbers are up 17 percent compared to the same period last year, and email spam rates have increased slightly over a three-month period, while phishing attempts and viruses attachments through email have decreased slightly.
