New DOUBLECUP ClickFix service hides malware in browser cache images
August 3, 2026
Back to all postsA new threat known as DOUBLECUP ClickFix has emerged, targeting Windows users through malicious browser cache images. This malware disguises itself as a legitimate software update for popular browsers like Google Chrome and Firefox. Once installed, it modifies the system's DNS settings to redirect web traffic to malicious sites, potentially exposing sensitive business data to cyber threats. The alarming aspect of this attack is its ability to bypass traditional security measures such as antivirus software. As Canadian SMB owners and IT managers, it is crucial to remain vigilant and educate employees about potential phishing attempts, implement multiple layers of defense including browser protection, and regularly update systems and software to prevent such threats from infiltrating your network.
