TA577, also known in the security industry as Hive0118, has targeted organizations with rogue email attachments that, when opened, steal Microsoft Windows NT LAN Manager (NTLM) authentication information. Researchers warn that the group's recent campaigns involved thousands of email messages sent to hundreds of entities. NTLM is the default authentication mechanism used on Windows networks when a computer attempts to access network resources or services. This article continues to discuss the malicious email campaign that steals NTLM authentication information.

In November 2023, security researchers at IBM Security Trusteer discovered malware called "Fakext," which uses a malicious Edge extension to execute man-in-the-browser and web-injection attacks. Since early November 2023, researchers have seen over 35,000 infected sessions, most of which are in Latin America (LATAM), with a smaller number in Europe and North America. The large number of infected sessions suggests a highly successful and widespread campaign. Fakext injects content onto the screen, including error messages, user forms, and notifications.

Misconfigured servers running Apache Hadoop YARN, Docker, Confluence, or Redis are the target of new Golang-based malware that automates the discovery and compromise of the hosts. The malicious tools used in the campaign exploit misconfigurations and an old Atlassian Confluence vulnerability to execute code on the system. Cado Security researchers discovered the campaign and examined the attack payloads, bash scripts, and Golang ELF binaries.

In February, two systems from the Cybersecurity and Infrastructure Security Agency (CISA) were hacked through issues with Ivanti products. Ivanti provides software to manage IT security and system access. This compromise proved that any company is vulnerable to hacking. Sources reveal that the two systems hit were the Infrastructure Protection (IP) Gateway which contains data about U.S. infrastructure, and the Chemical Security Assessment Tool that contains chemical company security plans. CISA has taken those systems and tools offline.

An ad fraud campaign uses thousands of hijacked legitimate domains and subdomains to send millions of spam emails, generating revenue for the threat actors. The "SubdoMailing" campaign distributes malicious ads to get fraudulent clicks for "Ad network" clients. The campaign, active since September 2022, involves hijacking no longer registered or abandoned domains and subdomains belonging to legitimate brands to send spam from attacker-controlled infrastructure. This article continues to discuss findings regarding the massive ad fraud campaign.
