Ongoing Campaigns

Malvertising campaign delivers Vidar and GandCrab

  • Malwarebytes Labs researchers detected a new malvertising campaign in which the Fallout Exploit Kit is used to distribute Vidar Stealer and GandCrab Ransomware.
  • According to their blog post, Vidar is a recently identified malware capable of stealing browser histories and cryptocurrency wallets, capturing instant messages, and can be customized depending on what data the attacker is interested in. Vidar also contains a loader feature that was used, in this case, to download GandCrab as a secondary payload.

‘Retro games’ iOS apps found to be communicating with Golduck malware server

  • Wandera security researchers discovered 14 iOS applications, all promoted as ‘retro-style’ games, that communicate with a C&C server associated with Golduck Malware. The game apps were observed sending data such as the IP address, device type, and in some cases location, to the Golduck server.
  • According to the researchers, although the apps themselves do not contain malicious code, they provide access to the user’s iOS device as the ad space could be used to display links that lure users into downloading malicious payloads. A secondary ad area on the application is also being used to provide content from a known malicious server.
  • Golduck Malware was previously found targeting Android devices, infecting them with malware and potentially leading to complete device compromise.



‘WhatsApp Gold’ hoax remerges

  • The campaign involves the distribution of hoax messages claiming that ‘WhatsApp Gold’ will be launched via a video called ‘Martinelli’, distributed via WhatsApp. The message then claims the video is a virus and warns users against clicking on it.
  • Despite there being no evidence of such videos being distributed, the messages reference an actual malware campaign from 2016. Users are warned against forwarding the message.
  • The referenced ‘WhatsApp Gold’ campaign was first identified in 2016 and involved users being lured into clicking links that offered them exclusive access to a ‘premium’ WhatsApp version, but actually infected their devices with malware.

Flaw in Skype for Android permits authentication bypass exposing user data  

  • Researcher Florian Kunushevci discovered a vulnerability in Skype for Android that permits an attacker to access photos and contacts, and open links in a browser via the app.
  • To successfully exploit the flaw, the attacker requires physical access to the target device. Next, the attacker needs to receive a Skype call and answer it, which would then allow them to access user data even when the device is locked.
