The U.S. State Department is offering up to $10 million for information leading to the identification or location of Zhang Yu, a Chinese national charged in the United States in connection with the 2021 Microsoft Exchange Server attacks known as HAFNIUM. The reward is for information leading to his identification or location, the news outlet  NTD reported  this week, citing a notice from the department's Rewards for Justice program. Zhang remains at large, U.S. authorities say, meaning he has not been arrested. The charges against him have not been tested in court. Rewards for Justice  is the State Department's national security rewards program. It says it has paid more than $250 million to over 125 people since 1984. Zhang is wanted for his alleged role in "malicious cyber activities against U.S. critical infrastructure," NTD quoted the notice as saying. The amount and that wording match an offer the program was already making  in January 2025 . That of...

SonicWall has released hotfixes for four flaws in its SMA1000 appliances, the gateways that give remote workers access to a company's network and applications. The most serious could allow an attacker without a login to send requests through the appliance and reach internal functions. SonicWall rates it 10.0 on the CVSS scale and says it has no evidence that any of the four flaws is being used in attacks. The most serious flaw, tracked as  CVE-2026-102255 , is a server-side request forgery (SSRF) bug in WorkPlace, the portal that SMA1000 users log in to. It exists due to an unintended access path through SonicWall and can be reached before authentication. An attacker who abuses that path could "reach internal functionality and perform unauthorized operations," SonicWall said in its  security advisory , dated October 6, without saying which functions. All four flaws affect SMA1000 models 6210, 7210 and 8200v on these platform-hotfix versions:

A critical vulnerability in LMCache , open-source software that speeds up large language model (LLM) servers such as vLLM, lets an attacker run code on the cache server without logging in, and no fixed version is available. The flaw is in LMCache's  multiprocess mode , where the cache runs as a standalone server that LLM workers reach over the ZeroMQ messaging library. A single network message to that server can run commands as the user the LMCache process runs as. The server can be reached from another machine only when an operator sets it to listen on a routable address, rather than the localhost it uses by default. JFrog disclosed the flaw  on October 7 and assigned it a severity score of 9.8 out of 10, in the critical range, the rating it gives a server bound to a routable address. The vulnerability, tracked as  CVE-2026-105192 , affects LMCache from version 0.3.9, released in October 2025, through 0.5.5, the latest stable release, and is also present in the ...

Cybersecurity researchers are calling attention to a new malware family that has been observed targeting exposed artificial intelligence (AI) and large language model (LLM) infrastructure with an aim to deploy cryptocurrency miners and further expand the scale of the botnet. The financially motivated campaign, dubbed Canto Incognito , has been found to install cryptocurrency miners, including XMRig and Iron, and connects victims to Kryptex, a Russian cryptocurrency mining service. "Compromised hosts are reused to expand the botnet," Lumen Black Lotus Labs said in a report shared with The Hacker News. "Infected servers are turned into scanners and exploit servers, allowing the actor to find and compromise additional vulnerable systems." The malware distributed as part of the campaign has been codenamed PoeLLM owing to what has been described as a "creative" technique that hides the command-and-control (C2) address within a poem the threat actors wr...

Threat actors have begun to exploit a newly disclosed critical security flaw impacting Atlassian Data Center products that could allow access to sensitive files under certain conditions. The arbitrary file access flaw, tracked as CVE-2026-21589 (CVSS score: 9.3) affects multiple products, including Bitbucket Data Center, Confluence Data Center, Jira Service Management Data Center, Jira Software Data Center, Bamboo Data Center, Crowd Data Center, Crucible, and Fisheye. "This arbitrary file access vulnerability allows an unauthenticated attacker to access specific files within the web application root directory in affected versions," the Australian company said. "Exploitation requires prior knowledge of the target file's exact name and path; this vulnerability does not allow attackers to enumerate or list directory contents. In some configurations, there may be sensitive files present that increase your risk." Atlassian said impacted Atlassian Cloud pro...
