Hardcoded account in Zyxel, whatsapp user’s data → facebook and news about Julian Assange

At the beginning of the year there is not much news, but we were able to collect a digest with the loudest and coolest news.

  • Vulnerabilities: Zyxel fail, cool bug in Google docs and new side-channel attack, + it’s recommended to patch Nvidia drivers;
  • Tools: Offensive staff only;
  • News: Julian Assange, whatsapp transfers your data directly to facebook and malware/hacking;
  • Research: High quality reports from bug hunters, red team materials and update for sysinternals.

CVE-2020-29583

More than 100 thousand Zyxel devices ended up with a backdoor – firewalls, VPN gateways, etc. contain a hardcoded login-password for remote admin access. Login zyfwp and password “PrOw! AN_fXp”.

Cool bug in Google Docs allowed viewing other people’s private documents by intercepting screenshots. The researcher earned $ 3,133.70 through the bug bounty program after discovering a vulnerability in Google Docs. This is because Google’s feedback tool could have been used to steal sensitive information.

The researcher explains that when attaching a screenshot of the Google Docs window, rendering the image requires passing the RGB values of each pixel to google.com, which then redirects those values to the feedback domain, which ultimately creates an image and sends it back as Base64. The researcher found a bug in the way these messages are sent feedback.googleusercontent.com. The bug made it possible to make changes to the frame, directing content to an arbitrary external site, steal or intercept screenshots intended for uploading to Google servers.

Security researchers at NinjaLab have developed a new side-channel attack CVE-2021-3011 to clone ECDSA keys stored in USB tokens based on NXP chips. The attack was demonstrated for Google Titan two-factor authentication tokens based on the NXP A700X chip, but theoretically applies to Yubico and Feitian crypto tokens using the same chip.

On February 8, 2021, the new Terms of Service will come into force for the WhatsApp messenger. On this day, the user must either agree to the transfer of data to the FB, or the user remains without an account.

In a previous update, WhatsApp gave users the option to “not provide Facebook with your WhatsApp account information.” In the latest update, WhatsApp dropped this option and users will have to accept the new terms and privacy policy if they want to continue using the messenger.
