The parameters distinguish program phases which run as separate processes, simultaneously. Map illustrating the countries Clipsa has targeted from August 2018 – July 2019 Graph illustrating Clipsa’s spread in time (hits) AnalysisĬlipsa uses a single executable binary with several parameters (command line arguments). We protect all our users against Clipsa and all of its components. In total, Avast protected more than 253,000 users more than 360,000 times, since August 1, 2018. We have also observed higher infection attempt rates in the Philippines, where Avast protected more than 15,000 users from Clipsa and in Brazil, protecting more than 13,000 users. The campaign is most prevalent in India, where Avast has blocked more than 43,000 Clipsa infection attempts, protecting more than 28,000 users in India from the malware. Once users begin the installation process, they deploy Clipsa on their machines and the malware immediately starts its malicious behavior.

Users who try to install these codecs for their media players inadvertently download malicious installers instead of clean ones. We estimate that the attack vector is most likely malicious codec pack installers for media players ( Ultra XVid Codec Pack.exe or Installer_x86-圆4_89006.exe). We also suspect they use the infected sites as secondary C&C servers to host download links for miners, or to upload and store stolen data. While we cannot say for sure, we believe the bad actors behind Clipsa steal further data from the breached sites. Once it finds a vulnerable site, it attempts to brute-force its way into the site, sending the valid login credentials to Clipsa’s C&C servers. Furthermore, Clipsa is capable of searching for and stealing wallet.dat files, and installing a cryptocurrency miner.Īdditionally, Clipsa uses infected PCs to crawl the internet for vulnerable WordPress sites. Once on an infected device, Clipsa can perform multiple actions, such as searching for cryptowallet addresses present in victims’ clipboards to then replace the addresses victims want to send money to with wallet addresses owned by the bad actors behind Clipsa. Several versions of Clipsa also deploy an XMRig coinminer to make even more money from infected computers.Ĭlipsa spreads as a malicious executable file, likely disguised as codec pack installers for media players.

Clipsa is a multipurpose password stealer, written in Visual Basic, focusing on stealing cryptocurrencies, brute-forcing and stealing administrator credentials from unsecured WordPress websites, replacing crypto-addresses present in a clipboard, and mining cryptocurrencies on infected machines.
