2015 Cellopoint email security review

Mobile malware's exponential growth

Malicious and high-risk apps have shown a substantial growth in 2015, mainly spread on Android devices. The alarming statistics show that while there were only 350,000 mobile malwares as of 2012, it is estimated to increase to 20 million by the end of 2016. As seen in the trend, hackers develop malwares on mobiles at a much higher rate than on PCs, which gives us an insight in how appealing mobiles are to hackers.

Anti-APT and anti-malware become mainstream requirement

According to data provided by CGAC (Cellopoint Global Anti-spam Center), number of spam per 100 emails dropped gradually each quarter in 2015: 80.3 spam per 100 emails in the first quarter, 79.7 in the second, 78.1 in the third and 78.0 in the fourth. The decrease in spam numbers might seem like good news for users, the reality might not be the case, because spam mails have evolved from traditional mass-volume, one-fit-all spam to sophisticated, individually-designed targeted attacks.

CelloLabs researchers observed and analyzed a wide range of spam mail activities from spams that contain ransomware spread all over the world, to regular spams that target everyday end users. We found that more and more hackers and commercial spies are using Advanced Persistent Threat (APT) and social engineering as their primary attack methods. These methods allow hackers to slowly but consistently penetrate traditional defense mechanisms such as firewall, anti-spam and anti-virus solutions, because these solutions are unable to respond unknown attacks like APT and social engineering. Traditional targeted countries such as the U.S., Russia and China are not the cyber criminals' only favorite anymore, with European and growing Asian countries joining the list.

Cellopoint team stressed that APT and targeted phishing emails have slowly grown out of control, which again indicates how vital anti-APT and anti-malware solutions have become a new necessity in the email security industry.
