F5 is warning BIG-IP admins that devices are being breached by "Skilled" hackers exploiting two recently disclosed vulnerabilities to erase signs of their access and achieve stealthy code execution. F5 has observed threat actors using the two flaws in combination, so even applying the mitigation for CVE-2023-46747 could be enough to stop most attacks.
Public exploit code is now available for the critical Cisco IOS XE vulnerability tracked as CVE-2023-20198 that was leveraged as a zero-day to hack tens of thousands of devices. Cisco released patches for most releases of its IOS XE software but thousands of systems continue to be compromised, internet scans show.
A security researcher has published a proof-of-concept exploit for Wyze Cam v3 devices that opens a reverse shell and allows the takeover of vulnerable devices. Security researcher Peter Geissler recently discovered two flaws in the latest Wyze Cam v3 firmware that can be chained together for remote code execution on vulnerable devices.
A new ongoing campaign dubbed EleKtra-Leak has set its eyes on exposed Amazon Web Service (AWS) identity and access management (IAM) credentials within public GitHub repositories to facilitate...
ESET researcher Matthieu Faou has exposed a new cyberattack from a cyberespionage threat actor known as Winter Vivern, whose interests align with Russia and Belarus. The attack focuses on exploiting a zero-day vulnerability in Roundcube webmail, with the result being the ability to list folders and emails in Roundcube accounts and exfiltrate full emails to an attacker-controlled server.
The attack can be launched against Macs, iPhones, and iPads running Apple's A-series or M-series chips. For macOS, the attack only works on Safari, but for iOS and iPadOS, there's a much larger attack surface.
A group of academics has devised a novel side-channel attack dubbed iLeakage that exploits a weakness in the A- and M-series CPUs running on Apple iOS, iPadOS, and macOS devices, enabling the...
Cloudflare on Thursday said it mitigated thousands of hyper-volumetric HTTP distributed denial-of-service (DDoS) attacks that exploited a recently disclosed flaw called HTTP/2 Rapid Reset, 89 of...
The Winter Vivern cyber spy group is exploiting an XSS zero-day vulnerability in attacks on European governments. Researchers at ESET, who discovered the activity, didn't name the specific government entities it targeted but given Winter Vivern's nexus to Russia and Belarus, they are likely to be adversaries of those countries.
