In the interest of secure computing, we encourage all readers to regularly apply software and OS security updates, and follow safe computing practices. With reports like these, it is becoming a challenge to predict what hackers will target next. We will be sure to keep you posted as soon as Piriform publishes the results of its ongoing investigation.
CCLEANER REVIEW 2018 UPDATE
The rate at which these users update to newer versions of the program is highly variable and the malware could still lurk around even though the rogue server in question has been disbanded. However, the fact that nearly 2.3 million users were affected is still a serious concern.
CCLEANER REVIEW 2018 UPGRADE
The company is urging all users to upgrade to version 5.34, which contains the correct clean code. The action of the second-stage payload is not yet detected.Īt this stage, Piriform is cautious not to speculate too much into how its binaries were compromised and is apparently taking actions to prevent it from happening again. All this information was encrypted and transmitted to a remote address (.x), which then sent a second-stage payload containing further encrypted information. It collected a host of information about the infected system including its name, software installed, MAC addresses etc. It downloaded on my windows 8 but will not download on my window 10 home. Reviewed in the United States on OctoI order this because I got a new computer and wanted to have it on it too so I paid 79 so I could put it on both my notebook and computer. Piriform says that the suspicious code stored certain information in the registry key, HKLM_Software_Piriform_Agomo that also included the IP address of the Command and Control (CnC) server. bond They say you can put it on more than one computer at home but not true. The highly obfuscated illegal code created a 16KB DLL that executed in a separate thread and continued to run in the background while the actual program was being run. Of particular importance is the fact that the original binary had a valid digital certificate, which could imply that Piriform's certification process itself was compromised. Hackers inserted a two-stage backdoor that could remotely execute code and transmit back user info in an encrypted form. In a technical blog post, Paul Yung, VP, Products from Piriform, detailed about the illegal code modification that affected nearly 2.27 million users of the product. This led to the conclusion that the program's binary was illegally modified to transmit user info to the hacker. On September 12, certain 32-bit versions of CCleaner () and CCleaner Cloud () were found to transmit data to an unknown IP address, prompting Piriform to start an investigation in collaboration with Avast Threat Labs. The malware is a backdoor that disguised itself within the app's runtime and therefore, went largely unnoticed until Piriform noticed something suspicious. CCleaner, the popular PC cleaning app from Piriform (now part of Avast), has been found to be infected with malware that can potentially sniff out user data in the background without the user even knowing it.
