Subsequently, in February and June 2022, the trojanized Q-Dir installers were transferred via remote support tools like helpU and ANYSUPPORT to two of the company's customers, an engineering and a manufacturing firm located in East Asia. Tick employs an exclusive custom malware toolset designed for persistent access to. "The purpose of these DLLs is to decode and inject a payload into a designated process." Then, in February and June 2022, the malicious Q-Dir installers were. "To maintain persistent access, the attackers deployed malicious loader DLLs along with legitimate signed applications vulnerable to DLL search-order hijacking," Muñoz said. In late February 2021, Tick emerged as one of the threat actors to capitalize on the ProxyLogon flaws in Microsoft Exchange Server as a zero-day to drop a Delphi-based backdoor in a web server belonging to a South Korean IT company.Īlso delivered during the intrusion were variants of a Delphi backdoor called Netboy (aka Invader or Kickesgo) that comes with information gathering and reverse shell capabilities as well as another downloader codenamed Ghostdown. Attack chains orchestrated by the group have typically leveraged spear-phishing emails and strategic web compromises as an entry point. Other lesser-known targets include Russian, Singaporean, and Chinese enterprises.

This program will never knowingly distribute any kind of malware. The program is not listed in the Windows Settings or Control Panel. "The attackers compromised the DLP company's internal update servers to deliver malware inside the software developer's network, and trojanized installers of legitimate tools used by the company, which eventually resulted in the execution of malware on the computers of the company's customers," ESET researcher Facundo Muñoz said. The program is regarded by the user and/or some websites as a potentially malicious. A cyberespionage actor known as Tick has been attributed with high confidence to a compromise of an East Asian data-loss prevention (DLP) company that caters to government and military entities.
