China”‘linked PlushDaemon hijacks DNS via ‘EdgeStepper’ to weaponize software updates
Hijacked update to backdoor deployment: With the network device serving as a stealthy redirect, PlushDaemon then exploits the hijacked update channel to gain access to end-systems. ESET observed how typical victim software (such as a Chinese input-method application) issues an HTTP GET to its update server, but because DNS was hijacked, the request lands at…

Chinese PlushDaemon Hackers Exploit EdgeStepper Tool to Hijack Legitimate Updates and Redirect to Malicious Servers
ESET researchers have uncovered a sophisticated attack chain orchestrated by the China-aligned threat actor PlushDaemon, revealing how the group leverages a previously undocumented network implant, EdgeStepper, to conduct adversary-in-the-middle attacks. By compromising network devices and redirecting DNS queries to malicious servers, PlushDaemon intercepts legitimate software updates and replaces them with trojanized versions containing the SlowStepper…

Blocking Traffic Manipulation in AWS Starts With IAM
Tl;DR Networking in the Cloud Without domain name resolution and effective traffic routing, the cloud breaks. This proved true last month, when a DNS issue affecting the AWS us-east-1 DynamoDB API endpoint disrupted operations at thousands of companies. While certainly an extreme example, it highlights how quickly a single networking issue can cascade, taking down……

Every significant CVE tells a story, known exploit activity, actor interest, proof-of-concept code or links to MITRE ATT&CK techniques. This external intelligence gives us the who and how behind potential exploitation.For example, when a privilege escalation vulnerability in Linux…

DNS DDoS Attacks Explained And Why Cloud DNS Is The Solution
Every time you load a webpage, send an email, or stream a video, the Domain Name System (DNS) silently performs its critical duty, translating easy-to-read names into complex numerical IP addresses. This fundamental function makes it the Achilles’ heel of the modern internet. As an essential service that all users and applications must rely on,……
