New Win-DDoS Flaws Let Attackers Turn Public Domain Controllers into DDoS Botnet via RPC, LDAP
A novel attack technique could be weaponized to rope thousands of public domain controllers (DCs) around the world to create a malicious botnet and use it to conduct power distributed denial-of-service (DDoS) attacks.
The approach has been codenamed Win-DDoS by SafeBreach researchers Or Yair and Shahak Morag, who presented their findings at the DEF CON 33 security conference today.
“As we

Researchers Detail Windows EPM Poisoning Exploit Chain Leading to Domain Privilege Escalation

Leaked Credentials Up 160%: What Attackers Are Doing With Them
When an organization’s credentials are leaked, the immediate consequences are rarely visible—but the long-term impact is far-reaching. Far from the cloak-and-dagger tactics seen in fiction, many real-world cyber breaches begin with something deceptively simple: a username and password.
According to Verizon’s 2025 Data Breach Investigations Report, leaked credentials accounted for 22% of breaches
