Silobreaker Daily Cyber Digest – 15 November 2018



New DarkGate malware targets Windows users in France and Spain

  • EnSilo researchers discovered a new cryptomining and ransomware campaign distributing malware dubbed DarkGate. The malware has multiple evasion techniques, allowing it to remain undetected by most antivirus solutions over long periods of time. DarkGate was found to bear similarities with a previously identified malware named Golroted.
  • DarkGate utilizes two infection methods that rely on distribution via Torrent files disguised as popular films and TV shows, that execute malicious VBScripts on victims’ devices. The malware was discovered to be capable of cryptomining, credential stealing, ransomware and remote-access takeovers.  
  • DarkGate targets Windows workstations, and has so far been aimed at users in Europe, particularly in France and Spain.

Ongoing Campaigns

Hackers sell luxury travel services at discount prices on underground markets

  • Motherboard has reported on the growing underground travel market selling luxury hotel rooms and flights at discount prices.

However, in some instances, Motherboard suspects bookings were obtained through hacking customers’ accounts or by using stolen credit card details.
  • Most of these discount travel services were found to be offered on Russian-language underground forums. Others were found on forums in English and Arabic. These services are believed to have been offered as early as 2005.



Researchers find large number of ATMs to be vulnerable to a series of attacks  

  • Positive Technologies researchers tested a variety of ATMs and found that 69% of them were vulnerable to Black Box attacks. Black Box attacks involve hacking the device to dispense bank notes.
  • For some of the models tested, the researchers found that these attacks can be carried out in just 10 minutes. The sampled ATMs include devices by NCR, Diebold Nixdorf and GRGBanking.
  • The research team also found 85% of tested ATMs to be poorly secured against network attacks such as spoofing processing centres to approve withdrawal requests or increasing the number of notes dispensed.



E-commerce sites often reinfected with Magecart malware after clean-up

  • Security researcher William de Groot discovered that online stores that have been infected by Magecart malware often get reinfected. His study of 40,000 domains revealed that 21.3% of the studied websites were reinfected with Magecart following the its removal.
  • De Groot also found that in some cases online stores got reinfected up to 18 times. Moreover, the researcher revealed that reinfections occur within shorter periods of time compared to clean-up times.



Mylobot malware distributes Khalesi malware in ongoing global campaign

  • CenturyLink researchers reported on the ongoing global campaign distributing the Mylobot downloader. The malware was found to be capable of executing any type of malicious payload following the infection of a victim’s device.

Hackers find flaws in iPhone X, Samsung S9 and Xiaomi Mi6 during Pwn2Own competition

  • During the Pwn2Own competition at the PacSec security conference in Tokyo, hackers discovered several bugs in iPhone X, Samsung Galaxy S9 and Xiaomi Mi6, that could allow attackers to completely takeover the targeted device.
  • Amat Cama and Richard Zhu of team Fluoroacetate hacked the Xiaomi Mi6 by using the touch-to-connect feature to navigate to a web page that exploited an out-of-bounds write vulnerability in WebAssembly leading to a code execution, and earning them $30,000.
  • The team also targeted the Samsung Galaxy S9 with a heap overflow in the baseband component, earning them a further $50,000. In addition, they also targeted the iPhone X with the JIT vulnerability in the web-browser and an out-of-bounds write bug for the sandbox escape and escalation, earning a final $60,000.



Cranes exposed to possible cyber-espionage attacks

  • In October, a vulnerability was discovered in Telecrane’s F25 Series remote controls used for cranes that allowed anyone to listen in on the remote control’s communications and subsequently be able to view commands, control the device, replay commands or stop the device from running.
  • The F25 series includes a wide range of applications used for cranes that could leave the machinery vulnerable. Telecrane has released a firmware update for the flaw.



Researchers discover new Meltdown and Spectre Attacks

  • Researchers from the Graz University of Technology and College of William and Mary, as well as some experts who discovered the original Meltdown and Spectre vulnerabilities have disclosed seven new variants of the Spectre and Meltdown attacks that leverage a technique known as transient execution.
  • The report states, ‘transient executions attacks leak otherwise inaccessible information via the CPU’s microarchitectural state from instructions which are never committed’. The researchers found that some transient execution attacks have not been successfully mitigated by the patches released for the original Meltdown and Spectre flaws, whilst others were overlooked.
  • The new attacks affect Intel, AMD and ARM processors.

Siemens release seven advisories for SIMATIC SCALANCE vulnerabilities

  • Members of China’s CNCERT/CC discovered two high severity flaws in SIMATIC S7 CPUs, which could allow an attacker to cause a denial-of-service condition by sending specially crafted packets, provided that the attacker has access to impacted devices on TCP port 102 via Ethernet, MPI or Profibus.
  • Exploitation could cause the targeted device to go into defect mode until it is manually rebooted.
  • Siemens also reported to customers that some SIMATIC human-machine interfaces (HMIs) are affected by a high severity flaw that can be exploited by an unauthenticated attacker to download arbitrary files from a device with no user interaction.
