JS_DLOADER.SMGA

JS_DLOADER.SMGA Description

JS_DLOADER.SMGA is a Trojan downloader that uses a recent Internet Explorer exploit to install a second PC threat, BKDR_AGENT.BCSG. BKDR_AGENT.BCSG, which then makes malicious modifications to Windows components, places an additional file onto the computer and then deletes itself to avoid detection. These attacks place your PC at a high level of risk for being compromised in a variety of ways, including losing personal information or inadvertently allowing criminals to control your computer. Because JS_DLOADER.SMGA may be downloaded even via safe websites that have been hacked, SpywareRemove.com malware researchers encourage you to use anti-malware protection if you insist on browsing the web with IE8 (which should be updated to reduce vulnerabilities like those that JS_DLOADER.SMGA exploits).

That ‘Pic’ That JS_DLOADER.SMGA Slaps Onto Your Hard Drive is Worse Than It Seems

JS_DLOADER.SMGA is a browser-based PC threat for Internet Explorer 8, and uses the vulnerability labeled CVE-2012-1875 to install the backdoor Trojan BKDR_AGENT.BCSG on your PC. Similar attacks by other PC threats can also use this vulnerability to install other forms of malicious software by way of hacked sites, malicious sites and compromised advertising networks. Since this vulnerability has been patched by Microsoft, updating IE8 should be adequate for protecting your computer from this particular exploit, if not necessarily from all similar attacks.

Although JS_DLOADER.SMGA deftly circumnavigates around default IE security like Data Execution Prevention in the course of its attack, JS_DLOADER.SMGA’s only payload is the installation of BKDR_AGENT.BCSG.

JS_DLOADER.SMGA places BKDR_AGENT.BCSG on your hard drive in the form of a fake .jpg file, although BKDR_AGENT.BCSG deletes itself after its own attacks, which create a backdoor vulnerability on your PC.

Saving Your Hard Drive from JS_DLOADER.SMGA and Why You Should Care

Backdoor exploits like those that are ultimately caused by JS_DLOADER.SMGA can be used to install practically any other type of PC threat, modify your system settings in dangerous ways, steal personal information and launch other attacks without explicit or visible symptoms. As a consequence of the danger involved in a successful JS_DLOADER.SMGA attack, SpywareRemove.com malware research team suggests using anti-malware scans to detect potential JS_DLOADER.SMGA payloads if you have any reason to suspect that your PC could have been targeted by JS_DLOADER.SMGA.

However, non-Windows PCs, non-IE8 browsers and browsers with JavaScript disabled are safe from JS_DLOADER.SMGA, which can only run under Java-enabled, IE8-based circumstances. Strong browser settings, such as disabling JavaScript, are always recommended by SpywareRemove.com malware experts as an easy method for closing off common infection vectors that are used by hacked and hostile sites. Despite this, these safeguards should never take the place of having anti-malware programs that can detect zero-day vulnerabilities that are adept at avoiding baseline web-browsing defenses.
