Silobreaker Daily Cyber Digest – 23 October 2019



Researchers observe new ransomware-as-a-service dubbed Project Root

  • Researchers at SentinelOne discovered a new ransomware-as-a-service (RaaS) called Project Root, being offered for both Windows and Linux systems, with support for Android to come soon. Its payloads are written in Golang, similar to previously observed RaaS like LockerGoga, allowing them to bypass traditional signature-based detection and static machine-learning detection engines.
  • Project Root is advertised as two versions that require an ‘up front’ payment. The standard version can generate unlimited ‘basic’ payloads via the sellers’ portal and includes management and key distribution components. The ‘Pro’ version, officially launched on October 17th, 2019, promises ‘better support, longer term of free updates and increased evasion options,’ as well as full access to the source code.
  • The researchers observed that up until around October 14th, 2019, the payloads did not work, making the RaaS appear to be a scam. However, since then the payloads have been functional.

New virus sample may be part of BadPatch malware set

  • Researchers at Fortinet analysed a recently discovered ‘multi-component python-compiled’ malware sample, dubbed B3hpy. The malware shares strong similarities with tools that were used in the BadPatch campaign. The BadPatch campaign was first reported in 2017 and was potentially carried out by the Gaza Hackers group, who have actively targeted the Middle East since 2012.  
  • The researchers analysed a sample of the malware which had been uploaded to VirusTotal. The executable file comes as an SFX executable file which contains a decoy document and a file designed to execute on 64-bits Windows machines. 
  • When the malware is installed on the target’s device it steals files, takes screenshots, steals passwords and more. Stolen data is exfiltrated to the attacker via SMTP. The researchers found that 96% of the malware victims reside in Palestine.

Ongoing Campaigns

Cache Poisoned Denial of Service attack used to knock websites offline

  • Researchers at the Technical University of Cologne developed a new attack, dubbed Cache Poisoned Denial of Service (CPDoS) which can be used to take legitimate websites offline by poisoning content delivery networks (CDN). CDNs store cached copies of websites and are widely used to alleviate pressure on web servers.
  • The attack works by continually connecting to a website with a request containing a malicious oversized HTTP header, until the request generates a new CDN entry. The CDN allows the malicious header to pass to the legitimate site at which point the header crashes the web server and generates an error page. This page is cached on the CDN and displayed to other visitors. By spreading to other nodes of the CDN’s network the cached error appears to create outages at legitimate sites.
  • The researchers developed three variants of this attack which focused on HTTP Header Oversize, HTTP Meta Character, and HTTP Method Override. The team also demonstrated the feasibility of the attack by launching it against a site’s CDN server and tracking it across the CDN provider’s network.



MedusaLocker ransomware infects victims worldwide

  • In mid-October 2019 researchers at MalwareHunterTeam uncovered a new ransomware, dubbed MedusaLocker. Since its initial discovery the malware has steadily infected a stream of users worldwide.
  • Following infection, the method of which is unclear, the ransomware creates registry values and sets a registry key to enable access to mapped drive. MedusaLocker then restarts LanmanWorkstation to ensure that mapped network drives are accessible, and that Windows networking is running.
  • The virus then terminates security processes, clears shadow volume copies and begins the encryption process. Files are encrypted with an AES key which is then encrypted with a RSA-2048 public key in the ransomware executable. A ransom note is then left on the victim’s system. At the time of writing no decryption key is available for MedusaLocker.

General News

Iranian hackers believed to be behind campaign targeting US satellite companies

  • According to The Daily Beast, court documents suggest that the FBI believes Iranian hackers are responsible for breaching computers belonging to US satellite companies. The Iranian Dark Coders Team, believed to be a collection of freelancers and responsible for multiple website hackings, is said to be behind the campaign.
  • The campaign involved the threat actors sending spear phishing emails purporting to be from the satellite imagery firm DigitalGlobe. The emails contained links to a website for downloads of a legitimate-looking app for finding satellite orbits. Another attempted hacking saw the threat actors using the compromised email address of a geology professor to send the spear phishing email. This one would ask the recipient to download and test a parallel image-processing application that is hosted on Dropbox.
  • The reason behind the campaign remains unclear. The US Department of Justice has not commented on the matter.
