FBI’s LockBit Takedown Postponed a Ticking Time Bomb in Fulton County, Ga. – Krebs on Security

The FBI’s takedown of the LockBit ransomware group last week came as LockBit was preparing to release sensitive data stolen from government computer systems in Fulton County, Ga. But LockBit is now regrouping, and the gang says it will publish the stolen Fulton County data on March 2 unless paid a ransom.

Mail in the middle – a tool to automate spear phishing campaigns

The idea is simple; take advantage of the typos that people make when they enter email addresses. If we positioned ourselves in between the sender of an email (be it a person or a system) and the legitimate recipient, we may be able to capture plenty of information about the business, including personally identifiable information, email verification processes, etc. This scenario is effectively a Person-in-the-Middle (PiTM), but for email communications.

Threat Actors Exploit Multiple Vulnerabilities in Ivanti Connect Connect and Policy Secure Gateways | CISA

Based upon the authoring organizations’ observations during incident response activities and available industry reporting, as supplemented by CISA’s research findings, the authoring organizations recommend that the safest course of action for network defenders is to assume a sophisticated threat actor may deploy rootkit level persistence on a device that has been reset and lay dormant for an arbitrary amount of time. For example, as outlined in PRC State-Sponsored Actors Compromise and Maintain Persistent Access to U.S. Critical Infrastructure), sophisticated actors may remain silent on compromised networks for long periods. The authoring organizations strongly urge all organizations to consider the significant risk of adversary access to, and persistence on, Ivanti Connect Secure and Ivanti Policy Secure gateways when determining whether to continue operating these devices in an enterprise environment.

“SubdoMailing” — Thousands of Hijacked Major-Brand Subdomains Found Bombarding Users With Millions of Malicious Emails

Guardio Labs uncovers a sprawling campaign of subdomain hijacking, compromising already over 8,000 domains from esteemed brands and institutions, including MSN, VMware, McAfee, The Economist, Cornell University, CBS, Marvel, eBay and others. This malicious activity, dubbed “SubdoMailing”, leverages the trust associated with these domains to circulate spam and malicious phishing emails by the Millions each day, cunningly using their credibility and stolen resources to slip past security measures.

In our detailed analysis, we disclose how we detected this extensive subdomain hijacking effort, its mechanisms, its unprecedented scale and the main threat actor behind it. Furthermore, we developedthe “SubdoMailing” checker — a website designed to empower domain owners to reclaim control over their compromised assets and shield themselves against such pervasive threats. This report not only sheds light on the magnitude of the issue but also serves as a call to action for enhancing domain security against future exploits.
