Cybersecurity researchers have disclosed details of a new malware called MDifyLoader that has been observed in conjunction with cyber attacks exploiting security flaws in Ivanti Connect Secure (ICS) appliances. According to a report published by JPCERT/CC today, the threat actors behind the exploitation of CVE-2025-0282 and CVE-2025-22457 in intrusions observed between December 2024 and July

A new report traces the history of the early wave of Chinese hackers who became the backbone of the state's espionage apparatus.

Google has released an update for its Chrome browser to patch six security vulnerabilities including one zero-day.

A threat actor with likely links to the Abyss ransomware group is leveraging an apparent zero-day vulnerability to deploy the "Overstep" backdoor on fully up-to-date appliances.

Stories about Chinese APTs attacking the US and Canada are plentiful. In a turnabout, researchers found what they believe is a North American entity attacking a Chinese entity, thanks to a mysterious issue in Microsoft Exchange.

Some 17 of the bugs are at high risk for exploits, including multiple remote code execution bugs in Office and SharePoint.

Everything feels secure—until one small thing slips through. Even strong systems can break if a simple check is missed or a trusted tool is misused. Most threats don’t start with alarms—they sneak in through the little things we overlook. A tiny bug, a reused password, a quiet connection—that’s all it takes. Staying safe isn’t just about reacting fast. It’s about catching these early signs

Cybersecurity researchers have shed light on a previously undocumented threat actor called NightEagle (aka APT-Q-95) that has been observed targeting Microsoft Exchange servers as a part of a zero-day exploit chain designed to target government, defense, and technology sectors in China. According to QiAnXin's RedDrip Team, the threat actor has been active since 2023 and has switched network
