SHENZHEN, CHINA, 17 MARCH 2011 – E-mail-based malware is rapidly increasing according to Network Box, which has reported an unusual increase in such activities over the past few days.
Network Box is a multi-award winning managed security services company, specialising in unified threat management (UTM).
The company claims such an unusual activity has not been noticed for many years and now suddenly this is happening all over the world.
Noting the malwares-per-hour statistics, Mark Webb-Johnson, CTO of Network Box, said malware is pouring in from hundreds of thousands of sources in e-mails with varying subjects.
Currently, Network Box’s heuristics (NBH-BGTRACK and zero-day Z-scan protection systems) are giving a tough fight to this problem but the increase is more than four times the baseline.
Also, all the samples the company has seen are emerging as never-before-seen zero-day threats.
“We expect that this increased activity is caused by botnet herders attempting to increase the size of their botnets and this will probably be followed by a corresponding increase in spam levels,” said Webb-Johnson.
Network Box has raised the alert condition to 3 and intends to continue monitoring the situation closely.
