The RAT King “NetSupport RAT” is Back in Action Via fake browser updates

In the perpetually evolving realm of cybersecurity, the reawakening of NetSupport RAT, a Remote Access Trojan (RAT), casts a looming shadow that beckons the attention of vigilant security professionals. 

This insidious malware, initially conceived as a bona fide remote administration tool, has metamorphosed into a potent weapon wielded by nefarious actors to infiltrate systems and establish unbridled remote control.

NetSupport Manager, the progenitor of NetSupport RAT, emerged as a genuine remote technical support tool three decades ago, adorned with capabilities for file transfers, support chat, inventory management, and remote access. 

However, the noble origins of this software have been marred by the malevolent intent of threat actors, who have adeptly exploited its functionalities for malicious endeavors.

The Surge Unveiled – NetSupport RAT on the Rise

A symphony of concern crescendos as the Carbon Black Managed Detection & Response (MDR) team, in harmonious collaboration with the Threat Analysis Unit, bears witness to a pronounced upswing in NetSupport RAT infections. 

The victim was presented with a fraudulent update that appeared to be a legitimate Google Chrome browser update.

This surge orchestrates a profound impact on sectors integral to the societal fabric – Education, Government, and Business Services.

The distribution ballet of NetSupport RAT unfolds through a myriad of tactics, from the deceitful allure of fraudulent updates to the clandestine choreography of drive-by downloads. 

Unlike its counterparts confined to the arsenals of specific threat actors, NetSupport RAT takes center stage in a diverse cast of malevolent entities, from fledgling hackers to seasoned adversaries.

NetSupport RAT’s intrusion choreography often involves beguiling victims into downloading counterfeit browser updates from compromised online stages. 

The infection waltz varies, adapting to the methodology of each threat actor, leaving a nuanced imprint on the cybersecurity canvas.
