Firms face cyberthreats once every 3 mins

Malware activity has become so pervasive that organizations experience a malicious email file attachment, web link or malware communication that evades legacy defenses up to once every three minutes, finds a new report.
 
Drawing on data gathered from 89 million malware events, the Advanced Threat Report released by FireEye, Inc., finds that on average, enterprises experience a malware event up to once every three minutes.
 
Across industries, the rate of malware activity varies, with technology companies experiencing the highest volume with up to one event per minute. Some industries are attacked cyclically, while some verticals experience attacks erratically.
 
Spear phishing remains the most common method for initiating advanced malware campaigns. When sending spear phishing emails, attackers opt for file names with common business terms to lure unsuspecting users into opening the malware and initiating the attack. These terms fall into three general categories: shipping and delivery, finance, and general business. The top term in malware file names, for example, was “UPS”.
 
ZIP files remain the preferred file of choice for malware delivery Malicious malware is delivered in ZIP file format in 92% of attacks.
 
Several innovations have appeared to better evade detection. Instances of malware are uncovered that execute only when users move a mouse, a tactic which could dupe current sandbox detection systems since the malware doesn’t generate any activity. In addition, malware writers have also incorporated virtual machine detection to bypass sandboxing.
 
The report also finds that attackers are increasingly using DLL files. By avoiding the more common .exe file type, attackers leverage DLL files to prolong infections.
 
 
“This report provides an overview of how attacks have become much more advanced and successful at penetrating networks, regardless of industry,” said Ashar Aziz, FireEye founder and CTO.
 
“As cybercriminals invest more in advanced malware and innovations to better evade detection, enterprises must rethink their security infrastructure and reinforce their traditional defenses with a new layer of security that is able to detect these dynamic, unknown threats in real time.”
 
“The high rate at which cyber attacks are happening illustrates the allure of malware,” said Zheng Bu, senior director of research. “Today, malware writers spend enormous effort on developing evasion techniques that bypass legacy security systems. Unless enterprises take steps to modernize their security strategy, most organizations are sitting ducks.”
