Silobreaker Daily Cyber Digest – 13 December 2018



Shamoon variants appear in the wild, possibly used in attack against Saipem

  • Chronicle researchers discovered that two new samples of Shamoon malware were uploaded to VirusTotal from Italy on December 10th, 2018.
  • The timing of the upload corresponds with the recent cyber attack against Italian oil company Saipem. In an update on the attack, Saipem claimed it was targeted by a Shamoon variant.
  • Bleeping Computer note that that one of the variants may have been uploaded to VirusTotal by Saipem in their efforts to determine the nature of the malware that affected them. However, Chronicle’s investigation is still ongoing, and no definite results have been produced to date.
  • Shamoon is disk-wiping malware that targeted Saudi Aramco in 2012, erasing data from over 35,000 devices. Four years later, in 2016, the malware was seen in attacks against private organizations in the Middle East.

Ongoing Campaigns

Operation Sharpshooter targets global defence and critical infrastructure

  • McAfee researchers discovered a new global campaign dubbed Operation Sharpshooter, that has focused on organizations predominantly in nuclear, defence, energy and financial sectors. In October and November 2018, the campaign targeted 87 organizations worldwide, primarily those based in the US.
  • The first stage of the attack involves a document containing malicious macros that, once enabled, download a second-stage implant dubbed by McAfee as Rising Sun. Rising Sun is a fully functional backdoor used for reconnaissance on the victim’s system. The information the implant gathers is used to determine the next steps of the operation. The backdoor uses source code from the Duuzer Trojan used by the Lazarus Group.
  • Based on several similarities with other Lazarus Group attacks, the researchers do not rule out the possibility of the Group being behind the operation, however they do warn these could just be false flags.

Trend Micro observe cryptocurrency spreading via old bugs on Elasticsearch

  • The attack utilised two vulnerabilities. These include CVE-2015-1427, a flaw in Elasticsearch’s Groovy scripting engine that allows remote attackers to execute arbitrary shell commands through a crafted script, and CVE-2014-3120, a flaw in the default configuration of Elasticsearch.
  • Once the attacker gains the ability to run arbitrary commands on the infected system, they can attempt to escalate privileges or pivot to other systems. The payload downloads two files, devtools and config[.]json. The script then deploys the CoinMiner cryptocurrency miner.
  • If other miners are detected in the system then running processes are stopped. The miner uses cron to run every ten minutes.

APT28’s Dear Joohn campaign targets NATO-aligned and former USSR states

  • Researchers from Palo Alto Networks’ Unit 42 identified a new campaign by APT28 dubbed Dear Joohn. Based on the analysis of the threat actor’s activity between mid-October to mid-November 2018, the researchers uncovered that the campaign delivered variants of either Zebrocy or Cannon, targeting government agencies of NATO-aligned and former USSR nation states across four continents.
  • The attack vector consisted of spear phishing emails sent from accounts registered to a legitimate Czech service provider. These distributed Word files containing generic lure images that tricked victims into enabling macros. The file names often featured topics relating to current events to entice users into opening the malicious attachments.
