Today, when Internet became the primary channel of information and entertainment, propagation of malicious
software is very simple and in general based on exploitation of security vulnerabilities which are
frequently discovered in popular web browsers and media viewers.
According to Common Vulnerabilities and Exposures database, only in 2010 there were discovered 114 security
vulnerabilities in Mozilla Firefox, 172 security vulnerabilities in Google Chrome, 49 vulnerabilities in Opera
and 68 in Microsoft Internet Explorer (5,6,7,8).
Quttera supplies cloud services providing protection from web based security threats and help
to keep web-surfing devices away from viruses, trojans, worms and other kinds of malicious software.
Quttera's malicious content detection services utilize cutting edge heuristic detection technologies capable
to detect fully new, previously unknown security threats as well as already known threats which are spread as a
part of legitimate web content included in web sites.
Our technology is based on years of research and systematic investigations of web based security threats and it provides very good(high rate)
capabilities in detection of JavaScript exploits, malicious PDF documents and media files that are downloaded
and accessed by web browser implicitly during web surfing. Our services run on remote servers and do not
require local installation.
There is no doubt that a web-based malware is an emerging security threat
for websites and web users. The dynamic content has increased the delivery
of sophisticated web threats that evade detection by traditional security technologies.
Hackers insensibly hack web-sites by exploiting security weaknesses of hosted web applications,
gain access to the hacked Web site and install malware files that further spread to mobile devices
and desktop stations.
In order to improve existing identification capabilities we have developed a
heuristic malicious content detection engine which is capable to recognize and protect from various
kinds of web-threats. Our malicious content detection engine comprises multiple non-signature based
investigation and analytic methods capable to identify JavaScript based attacks,
security vulnerability exploits, JavaScript obfuscation techniques and JavaScript packers
which are used to hide malicious content from signature/pattern based identification engines.
”Quttera” investigation engine embeds number of homemade execution emulators which penetrate
investigation content and detects web-treats regardless to targeted web browser or operating system.
Current engine version is capable to recognize and detect:
