In the bleeping article this is stated: "Please note. ![]() Windows Registry CCleaner Agomo Post 5_34 Reinstall. Should I be deleting this Agomo registry entry manually, and what other registry entries and files might have been missed by the v5.34 installer?ģ2-bit Vista Home Premium SP2 * Firefox ESR v52.3.0 * NS Premium v22.10.0.10 * MB Premium v3.2.2 * CCleaner Free v I wiped CCleaner v5.34 (originally installed 13-Sep-207) off my system today with the Free Revo Uninstaller v2.0.3 (advanced mode) and reinstalled with a fresh copy of ccsetup534.exe downloaded from the Piriform site ( /ccsetup534.exe 9,597 KB) but the Agomo registry entry at HKEY_LOCAL_MACHINE\SOFTWARE\Piriform\Agomo still persists. Updating CCleaner to v5.34 removes the old executable and the malware. The bleepingcomputer article states that " The malware was embedded in the CCleaner executable itself. I just read today's Piriform blog entry Security Notification for CCleaner v and CCleaner Cloud v for 32-bit Windows users as well as the bleepingcomputer article CCleaner Malware Incident - What You Need to Know and How to Remove about Piriform's infected 32-bit v5.33 installer. Last week I posted in geekandglitter's thread 32.59165 found by Zillya! about downloading two different installers for CCleaner Free v3.34 from the official Piriform site ( cc_setup534.exe 9,954 KB versus the ccsetup534.exe 9,597 KB) but my post in that thread was deleted by one of the forum mods on 1. How do I ensure that sure that this malware has been completely removed, short of restoring my system to a state prior to 1? Version 5.33 of the CCleaner app offered for download between August 15 and September 12 was modified to include the Floxif malware, according reports published by MorphiSec and Cisco Talos.I believe I was one of the 32-bit CCleaner users infected by the Floxif malware that was bundled with the previous v5.33 installer but the new v5.34 installer does not appear to be removing all traces of this malware off my system. The CCleaner malware fiasco has reached a new height according to new evidence, the attack may have infected the internal networks of technology giants like Google, Microsoft, and Sony. Initial findings suggest at least 18 such companies were targeted.Īvast, CCleaner developer Piriform’s parent company, detailed its progress on the malware investigation in a blog post. In its analysis, the company found evidence in that the malware has successfully sent a 2nd-stage payload to 20 machines in 8 organizations.Īlthough Avast didn’t disclose the names of the victims, one of the affected firms, Cisco’s research group, has identified 18 companies whose names appear in the list of domains communicated by the malware’s command and control (C2) servers. It is possible more companies were targeted.įor those who don’t know, a 2nd-stage payload is a malicious code (payload) that the initial stage (also a malicious payload) executes after downloading the essential bits it’s an advanced technique that attackers use to mask the size and the intent of the malware. In this case, the payload was a set of DLL files that integrates with Windows and sends user information such as IP address and list of software and hardware to the attackers. The list includes domains like “” and “” that are used by the employees of the said tech firms. Since there was a 2nd-stage payload, Avast reckons this was a typical watering hole attack where the attackers initially target a large group victims, receive information, and infect only a certain set of entities. In this case, the actual targets were large tech companies and the probable intention was IP theft. ![]() It is now estimated that only 700,000 Windows PCs were affected by the malware, which is down from the earlier estimates of 2.3 million users. ![]() Yung says the attack was limited to CCleaner and CCleaner Cloud on 32-bit Windows systems fortunately, most modern PCs will likely be running the 64-bit. The malware attack infected over 2.3 million users who downloaded or updated the CCleaner app from the official website with the compromised version of the software in August and September last year. At present, it’s not clear if any of the aforementioned companies were infected.
