Ongoing Campaigns

Over 100,000 PCs in China infected with ransomware

  • The “poorly written” ransomware encrypts files and steals credentials for Chinese online services including Alipay, QQ and Baidu Cloud. It has been dubbed “WeChat Ransom” in some reports, and demands 110 yuan ($16) payable via the WeChat payment service.
  • According to researchers at Huorong, the malware’s authors are using a Chinese social networking service called Douban to send commands. Tencent have stated that the malware propagated through over 50 compromised applications, some of which are designed to manage QQ accounts.

  • The applications instructed users to touch the biometric scanner to view their diet recommendations and calorie trackers, but instead the fingerprint was used to authorise a payment of at least $99.99.
  • The applications have since been removed from the Apple App Store.

Microsoft releases analysis of cyberattack targeting US organizations

  • In contrast to some security researchers, Windows Defender Research stated that there is insufficient evidence to attribute the attack to YTTRIUM, a group that largely overlaps with APT29 or CozyBear.
  • Microsoft researchers note that the attack targeted mainly US organizations involved in policy-making or politics. Spear-phishing emails mimicked OneDrive sharing notifications from US Department of State employees.
  • Clicking on a link initiated an exploit chain that implanted a DLL backdoor onto machines, giving attackers remote access.

Vulnerabilities

Critical vulnerabilities patched in Google Android

  • 11 critical bugs, including four remote code execution flaws (CVE-2018-9549, CVE-2018-9550, CVE-2018-9551 and CVE-2018-9552) were patched by the Google Security team in their latest update. The vulnerabilities could have allowed an attacker to use a specially crafted file to execute code as a privileged user.

Machine-to-machine protocols open to abuse

  • Researchers at Trend Micro analysed two popular machine-to-machine protocols, ‘Message Queuing Telemetry Transport’ and ‘Constrained Application Protocol’, both used in Industrial Control Systems. The vulnerabilities discovered allow a malicious actor to either execute arbitrary code or cause a denial-of-service condition, which could pose a large risk to an industrial system.
  • There is no evidence to suggest that any actors or malware have leveraged these protocols, but researchers believe it will not take long until they are used for malicious activity.
