Cloudmark's 2014 Annual Security Threat Report

It's been a hot year for DNS. In our 2014 Annual Security Report we take a look at various forms of DNS abuse including DNS amplification, tunneling, exfiltration, and a study of DNS resource exhaustion at a major ISP. In the email space, bootleg Viagra® spam is a staple. This year, Cloudmark commissioned a chemical analysis of various samples from these fake pharmacies to determine just how legitimate and possibly dangerous these pervasive ads might be. Mobile customers have had their own woes this year with the largest targeting of Apple iMessage by spammers seen to date and we completed similar investigative research into this campaign. Our report details an investigation into the origins and on-going legal battle against these spammers and their evolving campaigns.

  • Domain Name System (DNS) infrastructure is critical to both the Internet and most private networks, however, many recent events have shown that it is vulnerable to attack, affecting millions of users when it goes down. There are tools and processes enterprises and service providers can use to protect DNS infrastructure but real protection is difficult to achieve due to the scope of the problem. This webinar provides a detailed look at the threats to DNS infrastructure and how those threats can be mitigated.

  • This webinar discusses how Application-to-person (A2P) SMS has increasingly become a key method for organizations to communicate with their customers. This has been driven by the ubiquity of mobile phones and the universality of SMS. Unfortunately, this has also lead to a massive growth in messages being sent through illegitimate routes that bypass the operators’ billing systems. This is commonly referred to as grey routes carrying grey traffic, and is a tactic commonly used by third-party aggregators to boost their own profitability. The result is lost revenue for mobile operators who often do not have visibility and control of messages on their network.

  2. North Korea: Hackers or Hacked?

    Jan 9, 2015 by Andrew Conway

    Attempting to attribute the Sony Pictures Entertainment attack to North Korea is complicated by the fact that a worm active in that country may be allowing foreign hackers access to computers within North Korea. While there is no evidence computers infected with this worm were involved on the attack on Sony, any attribution based on […]
