Installing cracked or pirated software versions is never recommended owing to the underlying security threats. The researchers have shared the technical details of this campaign in a blog post. Hence, the attackers get ample time to continue stealing data and spreading the infection to other systems. Since all these activities happen in the background, the victims may seldom detect the malware infection. These include stealing stored information and login credentials from browsers, crypto wallet data, and scanning and extracting data from the clipboard. Once the malware reaches the target system, it gains persistence and executes malicious activities. The attackers have also protected the file with passwords (that they openly advertise to the victims) to ditch malware detection. Since the attackers abuse generally trusted file-sharing platforms in this campaign, the victims will likely fall to downloading the malicious file. This hosting site offers the file with the cracked version. Upon visiting such a malicious link, the user reaches a seemingly legit hosting site like after several redirects. Thus, they increase the chances of those websites tricking users.

They even employed BlackHat SEO techniques to make those sites acquire top positions on Google SERPs. Hence, malicious campaigns exploiting this aspect of public interest prove lucrative for the attackers.īriefly, the attackers have set up various malicious sites offering the CCleaner pirated versions.

Since users are frequently interested in getting cracked versions of premium apps, such offers quickly attract their attention. The campaign, identified as “FakeCrack”, spreads a potent data-stealing trojan by impersonating pirated CCleaner app versions. Researchers from Avast have warned users about a severe malware campaign exploiting their CCleaner tool. Once downloaded, the malware sneakily steals data and cryptocurrency details from the victim’s device. This malware campaign employs all the legit means, including Google Search results, to lure users.

Zscaler Cloud Security Platform provides native SSL inspection.Researchers have discovered a new malware campaign in the wild targeting Windows users by mimicking cracked CCleaner. Over 60% of Internet traffic is over SSL, yet most advanced threats hide in SSL. SSL inspection is necessary to protect organizations. Here is a sample Cloud Sandbox report from one such detonation: Zscaler Cloud Sandbox successfully detected the payloads from this compromise. Zscaler added multiple signatures and indicators for blocking the original payloads as well as post-infection activity shortly after the information was disclosed to help any affected organizations in their remediation efforts.Ĭloud Sandbox provides the best line of defense in a proactive manner against these threats. How Zscaler Can Help with Preventative Measures The Zscaler team has been actively monitoring this issue over the past 72 hours and has added multiple protections to block the payloads as well as post-infection activity for the backdoor module.Īvast contacted all the impacted customers and revoked the legitimate certificate that was used to sign the compromised version of CCleaner package and issued an updated version of the package.

It is important to note that the malicious CCleaner installer package was delivered using CCleaner’s software update infrastructure over HTTPS and was signed using a legitimate certificate. Per Avast, 700K users downloaded and installed the compromised version of CCleaner, however, only the 20 users that belonged to the targeted organizations were served with a second stage payload.

Users from a very targeted list of organizations including Microsoft, Cisco, Intel, VMware, Sony, etc., were the only ones to be served a second stage malware payload.

The injected malicious code causes the compromised machine to communicate back to a predetermined C&C server (hardcoded IP addresses and DGA domains) to report infection and download a second stage malware payload. Attackers managed to compromise the software update infrastructure sometime in August 2017 and inject malicious code in the CCleaner update v5.33 and cloud version v1.07. CCleaner is a very popular file system and registry clean up utility that optimizes performance by removing unneeded registry entries and files. Earlier this week, Avast, a multinational security software vendor, reported a compromise of their Windows system utility CCleaner.
