Threat Intelligence reports

  • Check Point Research has encountered several attacks that exploit vulnerabilities on Linux devices using a new malware variant, called FreakOut. The threat actor behind the attacks infected many devices and incorporated them into a botnet, which in turn could be used for DDoS attacks and crypto-mining.

Check Point SandBlast, IPS and Anti-Bot provide protection against this threat

  • Check Point Research in collaboration with Otario, has uncovered a large-scale phishing campaign where the attackers unintentionally left over a thousand stolen log-in credentials accessible to the public by a simple Google search.
  • Check Point research has found a new malware loader by the North Korea-linked APT group Lazarus, reusing old doc file decoy and macros, and using VBS scheduled task for persistence.
  • A new malware has been discovered in the SolarWinds investigation. Named RainDrop, the malware is a loader that delivers a Cobalt Strike payload. On a similar note, Microsoft has released a deep dive into the Solorigate second-stage activation from SUNBURST to TEARDROP and the recent RainDrop.

Check Point Anti-Bot and Anti-Virus provide protection against this threat (Backdoor.Win32.SUNBURST; Trojan.Win32.TearDrop)

  • Researchers have warned of a publicly available fully functional exploit that could be used to target SAP enterprise software, exploiting a vulnerability that stems from a missing authentication check in their solution manager (CVE-2020-6207). A patch to this vulnerability was released in March 2020.
  • Research shows how Microsoft Remote Desktop Protocol (RDP) can be exploited to amplify distributed denial-of-service (DDoS attacks), with more than 14,000 servers vulnerable.
