We unravel the details of two large-scale StrelaStealer campaigns from 2023 and 2024. This email credential stealer has a new variant delivered through zipped JScript.

Last year, we again witnessed the power of community-driven security efforts as researchers from around the world contributed to help us identify and address thousands of vulnerabilities in our products and services. Working with our dedicated bug hunter community, we awarded $10 million to our 600+ researchers based in 68 countries.
In late 2023 and early 2024, the ransomware ecosystem experienced repeated disruption of its most prolific Ransomware-as-a-Service (RaaS) groups at the hands of international Law Enforcement (LE). Alphv’s dark web data leak site was seized, then unseized, then re-seized in a December 2023 law enforcement operation that seemingly failed to deter the group – until AlphV ultimately claimed to disband via an apparent exit scam, immediately following a high-profile attack against Change Healthcare in March 2024. LockBit experienced a far more dramatic and well-marketed disruption, “Operation Cronos,” in February 2024, leading to the compromise of its infrastructure, internal operational details, and data. While LockBit has ostensibly continued operations, its highly publicized disruption raises the question of whether the group will be able to continue operating and attracting affiliates at the level they once enjoyed.
This joint guide, Understanding and Responding to Distributed Denial-Of-Service Attacks, addresses the specific needs and challenges faced by organizations in defending against DDoS attacks. The guidance now includes detailed insight into three different types of DDoS techniques:
Volumetric, attacks aiming to consume available bandwidth.
Protocol, attacks which exploit vulnerabilities in network protocols.
Application, attacks targeting vulnerabilities in specific applications or running services.
Huntress recently detected interesting activity on an endpoint; a threat actor was attempting to establish a foothold on an endpoint by using commands issued via MSSQL to upload a reverse shell accessible from the web server. All attempts were obviated by MAV and process detections, but boy-howdy, did they try!
A new Denial-of-Service (DoS) attack targets application-layer protocols that draw on the User Datagram Protocol (UDP) for end-to-end communication. The vulnerability affects both legacy and contemporary protocols. Discovered by Christian Rossow and Yepeng Pan, the attack puts an estimated 300,000 Internet hosts and their networks at risk.
