New Threats

Several malware strains and vulnerabilities emerged this week. Microsoft warned that the Fancy Bear threat group was targeting sporting and anti-doping organizations across the world. Researchers have discovered a new ransomware called FuxSocy that borrows several behavioral traits from the Cerber Ransomware. Meanwhile, European authorities have released patches for major vulnerabilities in the eIDAS authentication system.

  • Microsoft has published a report warning that the Fancy Bear threat group is targeting sporting and anti-doping organizations around the world. The report said that at least 16 organizations were targeted in a recent wave of attacks that began on September 16, 2019.
  • A new ransomware called FuxSocy that shares a lot of similarities with the Cerber Ransomware has been discovered. After encrypting the files, it leaves a ransom note asking the victims to get in touch through the ToxChat messaging application. Because this is a recently discovered ransomware, a free decryptor is not available yet.
  • Two vulnerabilities have been patched in the EU’s electronic IDentification, Authentication and trust Services (eIDAS) system. These security flaws could potentially let attackers pose as an EU business or citizen by allowing them to provide fake certificates during the authentication process.
  • Researchers have uncovered a Maze ransomware campaign in Italy. This campaign sends spam emails that pretend to be from the country's Tax and Revenue Agency. The emails claim to contain new guidelines for citizens and businesses.

  • A security researcher identified vulnerabilities in the API and firmware of Xiaomi FurryTail smart pet feeders. Without requiring a password, the feeding schedules on 10,950 devices could be reportedly modified by exploiting these vulnerabilities. It was also said that malicious attackers could hijack the pet feeders into an IoT DDoS botnet by leveraging these flaws.
  • A new variant of the Adwind remote access trojan that targets Windows and Chromium-based browsers has been discovered. This variant is delivered by a JAR (Java Archive) file through phishing emails or legitimate sites serving insecure third-party content. To remain undetected, this malware disguises its behavior by acting like a Java command.
  • A new malware strain dubbed ‘xHelper’ has reportedly infected 45,000 devices. It reinstalls itself even after manual uninstallation or factory resets. Its capabilities include displaying ads and downloading other threats on the infected device.
  • Rittal’s SK 3232-series chiller for cooling IT applications was found to have two critical vulnerabilities. These flaws allow attackers to potentially cause disruptions by turning the coolers on or off and changing the temperature. The impacted systems are said to be deployed in a number of industries across the world.
  • Researchers from FireEye have discovered the new MessageTap malware created by the Chinese state-sponsored hacking group APT41. The malware targets Short Message Service Center (SMSC) servers run by telecom operators in order to steal incoming SMS messages.
  • A new variant of the Gafgyt malware has been found targeting routers made by Zyxel, Huawei, and Realtek. Over 32,000 routers are affected by the vulnerabilities (CVE-2017-18368, CVE-2017-17215, CVE-2014-8361) that are exploited by this malware. The malware exploits target devices to conduct botnet attacks against gaming servers.
  • A popular Android keyboard app a.type with over 40 million downloads has been found conducting fraudulent transactions from targeted devices. The app tried to execute 14 million transactions amounting to $18 million from 110,000 Android devices. The malicious app was removed from Google Play Store in June 2019.
  • Google has disclosed an actively exploited zero-day vulnerability in the Chrome web browser. The vulnerability in question is a use-after-free bug designated as CVE-2019-13720. Google has fixed the issue in the new v78.0.3904.87 release of Chrome.
