Malware

New node.js trojan MonsterInstall targets video gamers

  • Doctor Web researchers observed the trojan, named MonsterInstall, being distributed via websites which contain video game cheats.
  • When users attempt to download cheats they also download a 7zip archive containing an executable file which downloads the cheats and the trojan components. Upon launch MonsterInstall gathers information about the infected systems which is then relayed to the malware authors server. When a response is registered, the malware installs itself in the autorun and begins to mine TurtleCoin cryptocurrency.
  • To spread the malware more effectively the authors of MonsterInstall own several video game cheat websites and have also infected sites that are owned by others.  SimilarWeb statistics show that these websites are visited at least 127,400 times per month.

URLZone is the top malware in Japan’s threat landscape

  • Researchers at Proofpoint believe that URLZone malware campaigns are being carried out by a single high-volume actor operating primarily in Japan and Italy. Many of the email campaigns reference invoice or payment requests and are targeted against the banking sector.
  • Researchers observed that URLZone malware often works in tandem with the Ursnif trojan. URLZone is used as the initial payload and determines if the host environment is suitable. If deemed suitable, URLZone downloads Ursnif which begins to steal information.
  • Researchers also observed Emotet malware being widely distributed. Growing instances of URLZone and Emotet attacks via email suggested to researchers that attackers had ‘cracked the code’ for crafting convincing email attacks in the Japanese language.

Oracle patches critical code-execution vulnerability in WebLogic server

  • Researchers at KnownSec 404 Team reported the vulnerability, tracked as CVE-2019-2729, on June 15th, 2019. The vulnerability allows attackers to run malicious code on vulnerable systems due to a bug in the data deserialization process inside WebLogic Servers. Moreover, the attacker does not need to know a remote server’s credentials, therefore attacks can be launched against any internet-accessible WebLogic instance.
  • The KnownSec 404 Team claim that the vulnerability exploited a new bug to bypass patches for CVE-2019-2725, a zero day which was exploited in the wild before being patched in April.
