Hackers Hijack HBO Max Reddit Account to Push 108 ClickFix Malware Ads
Hijacked verified HBO Max Reddit account ran 108 ClickFix malvertising ads delivering AMOS infostealers, Windows loaders, and crypto clipboard hijackers.
HudsonRock and ADAMnetworks identified a cross-platform ClickFix operation dubbed PasteSwitch that abused the compromised verified Reddit account u/hbomax to publish 108 malicious ads over 48 hours, using domains like hbomaxx[.]us and codex-craft[.]com. macOS victims run curl/zsh commands delivering AMOS-related stealers and fake wallets, while Windows users get an InstallFix route using mshta and PowerShell that loads Amatera in memory and disables AMSI. The operation's AnimateClipper and ZigClipper families hijack clipboards to swap cryptocurrency addresses, with C2 domains rotated via Binance Smart Chain contracts. Reddit paused the ads and is investigating.
Unpatched Zimbra servers are falling to CVE-2026-73570 attacks
Attackers are exploiting unpatched Zimbra servers via CVE-2026-73570; 274 instances compromised, and CISA added the flaw to its KEV catalog.
The Shadowserver Foundation counted at least 274 compromised internet-facing Zimbra Collaboration Suite instances exploited through CVE-2026-73570, up from 155 on August 20. The unauthenticated code injection flaw affects servers with the optional zimbra-snmp package and SNMP notifications enabled, allowing arbitrary OS command execution via crafted SMTP requests. Synacor patched the issue in ZCS v10.1.20 on July 20, 2026, and at least 8,200 instances remain unpatched. CISA added the flaw to its Known Exploited Vulnerabilities catalog and gave US federal civilian agencies three days to remediate and check for compromise.
Srsly Risky Biz: China's Private Sector Botnets Are Worth Disrupting
DoJ seized domains of Chinese espionage botnet platforms QScan and QTRouter, run by private firm QTFY for MSS and PLA targeting.
The US Department of Justice disrupted QScan, a distributed vulnerability scanning system with nearly a decade of internet scanning data, and QTRouter, a covert communications platform routing traffic through compromised IoT devices, operated by QTFY under Chinese company Nanjing Xinjiuwei Network Technology. FBI and NSA advisories say QTFY customers include China's Ministry of State Security and the People's Liberation Army, targeting federal agencies, the US Senate, hospitals, telecoms and financial institutions. This is the third Chinese state-backed botnet disrupted since December 2023, following the KV botnet (Volt Typhoon) and Raptor Train (Flax Typhoon), and a sister network, JDY, has more than doubled since the KV disruption. Separately, the Qilin ransomware group claimed a breach of the ATF's CALEA system, briefly publishing 6.3 GB of case folders and forensic data.
