Hackers hijack D-Link, Ubiquiti devices to resell your stolen bandwidth

BleepingComputer

A recent campaign has targeted D-Link and Ubiquiti devices across 34 countries, allowing hackers to hijack these devices to create a commercial residential proxy network. This practice, known as proxyjacking, enables attackers to monetize stolen bandwidth from unsuspecting users. The impact is significant as it not only affects individual users' internet speeds and data privacy but also raises concerns about the security of these widely used devices. Users whose devices have been compromised may find their internet connections slower and could potentially face additional security risks if their devices are manipulated for illicit purposes. The situation underscores the need for users to secure their devices and remain vigilant against unauthorized access.

Citizen Lab Traces Zero-Click Candiru Spyware Infections at Al Jazeera to Targeted Online Ads

The Hacker News

Researchers from Citizen Lab reported that the Israeli spyware company Candiru has successfully infected devices at Al Jazeera using zero-click attacks via online advertisements. This means that users did not need to interact with the ads for the malware to activate; it could run automatically when an ad loaded, even if it was hidden from view. This incident raises serious concerns about the security of digital advertising and how it can be exploited to target specific organizations. Al Jazeera, a prominent news network, is particularly significant as it plays a crucial role in global media coverage. The ability for spyware to infiltrate devices without any user action emphasizes the need for stronger security measures in ad systems and for organizations to be vigilant against such sophisticated attacks.
