ServHelper

By GoldSparrow in Backdoors

ServHelper is a threatening malware infection. ServHelper does not attack alone; ServHelper is part of a dual malware kit that includes a malware component known as FlawedGrace. Even though these two malware components are delivered together, they are not labeled as a package and are generally studied and labeled separately. Each component of this attack, ServHelper, and FlawedGrace focuses on a different aspect of the attack and operation. Attacks involving ServHelper target high-profile entities that may include large companies and financial institutions. The ServHelper attack has been linked to a criminal group known as TA505. This group has been linked to various high-profile malware campaigns, including spam campaigns used to deliver Dridex, which possibly were also responsible for the creation of Locky, one of the most infamous ransomware threats. The current TA505 attacks, apart from ServHelper, involve the Globe Imposter Ransowmare variants and a Trojan downloader known as QuantLoader to carry out malware campaigns.

What is the Meaning of the ServHelper Attacks

ServHelper attacks were first observed in April 2019. This combo of ServHelper and FlawedGrace is used to infiltrate the victim's PC. ServHelper creates a backdoor on the infected computer device and then FlawedGrace functions as a Trojan downloader, installing other malware onto the victim's computer. These two components work together, and the loader module can be used to update the ServHelper component to make the attack more effective and keep it up-to-date. ServHelper works in the background silently, allowing criminals to monitor a computer to keep track of the victim's activities. FlawedGrace, on the other hand, seems to be used on business networks to collect data and install other malware.

How ServHelper is Delivered to Victims

There's a single infection vector in association with the ServHelper campaign. Previous TA505 attacks have involved a wide variety of attack vectors, ranging from social engineering and spear-phishing emails to malware exploits and direct attacks. The most common way to deliver ServHelper, however, seems to be spam email attachments taking advantage of vulnerabilities in Microsoft Office to deliver ServHelper and other malware to the victim's computer. Once ServHelper is installed, ServHelper functions as a typical backdoor Trojan. ServHelper receives its name due to the use of a DLL file named 'ServHelper.dll' that creates a connection between the infected computer and its Command and Control server. ServHelper has a wide variety of features that allow it to carry out attacks on the victim's computer and is updated by its controllers actively.

ServHelper Poses a Significant Threat to Businesses and Computer Users

While most individual computer users may not expect to become infected as part of the ServHelper campaign, large businesses, retail stores, and financial institutions are at risk for ServHelper infections and other attacks that may endanger their data. Therefore, you should take effective precautions to ensure that all of your devices are protected against ServHelper. First, make sure that all software is fully up-to-date. Also, use a reliable spam filter and to make sure that any unsolicited email messages and attachments are treated with suspicion. Furthermore, computer users are strongly urged to use a security program to intercept the ServHelper infection and to remove it and its associated malware component from a computer if any trace of infection is found on it. It also is crucial to educate computer users, particularly staff at a business, to ensure that they do not fbecome prey to social engineering and spam email campaigns.
