The U.S. government is warning about the resurgence of BlackCat (aka ALPHV) ransomware attacks targeting the healthcare sector as recently as this month. "Since mid-December 2023, of the nearly 70 leaked victims, the healthcare sector has been the most commonly victimized," the government  said  in an updated advisory. "This is likely in response to the ALPHV/BlackCat administrator's post encouraging its affiliates to target hospitals after operational action against the group and its infrastructure in early December 2023." The alert comes courtesy of the Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Security Agency (CISA), and the Department of Health and Human Services (HHS). The BlackCat ransomware operation suffered a major blow late last year after a coordinated law enforcement operation led to the  seizure of its dark leak sites . But the takedown turned out to be a failure after the group managed to regain control of the...

Traditional perimeter-based security has become costly and ineffective. As a result, communications security between people, systems, and networks is more important than blocking access with firewalls.  On top of that, most cybersecurity risks are caused by just a few superusers – typically one out of 200 users.  There’s a company aiming to fix the gap between traditional PAM and IdM solutions and secure your one out of 200 users –  SSH Communications Security.   Your Privileged Access Management (PAM) and Identity Management (IdM) should work hand in hand to secure your users’ access and identities – regular users and privileged users alike. But traditional solutions struggle to achieve that.  Microsoft Entra manages all identities and basic-level access. With increasing criticality of targets and data, the session duration decreases, and additional protection is necessary. That's where SSH Communications Security helps Let’s look at what organizations need...

Mexican users have been targeted with tax-themed phishing lures at least since November 2023 to distribute a previously undocumented Windows malware called  TimbreStealer . Cisco Talos, which  discovered  the activity, described the authors as skilled and that the "threat actor has previously used similar tactics, techniques and procedures (TTPs) to distribute a banking trojan known as  Mispadu  in September 2023. Besides employing sophisticated obfuscation techniques to sidestep detection and ensure persistence, the phishing campaign makes use of geofencing to single out users in Mexico, returning an innocuous blank PDF file instead of the malicious one if the payload sites are contacted from other locations. Some of the notable evasive maneuvers include leveraging custom loaders and direct system calls to bypass conventional API monitoring, in addition to utilizing Heaven's Gate to execute 64-bit code within a 32-bit process, an approach that was also rece...

In a new joint advisory, cybersecurity and intelligence agencies from the U.S. and other countries are urging users of Ubiquiti EdgeRouter to take protective measures, weeks after a botnet comprising infected routers was  felled by law enforcement  as part of an operation codenamed Dying Ember. The botnet, named MooBot, is said to have been used by a Russia-linked threat actor known as APT28 to facilitate covert cyber operations and drop custom malware for follow-on exploitation. APT28, affiliated with Russia's Main Directorate of the General Staff (GRU), is known to be active since at least 2007. APT28 actors have "used compromised EdgeRouters globally to harvest credentials, collect NTLMv2 digests, proxy network traffic, and host spear-phishing landing pages and custom tools," the authorities  said  [PDF]. The adversary's use of EdgeRouters dates back to 2022, with the attacks targeting aerospace and defense, education, energy and utilities, governments, hospit...

Tracked as  CVE-2023-40000 , the vulnerability was addressed in October 2023 in version 5.7.0.1. "This plugin suffers from unauthenticated site-wide stored [cross-site scripting] vulnerability and could allow any unauthenticated user from stealing sensitive information to, in this case, privilege escalation on the WordPress site by performing a single HTTP request," Patchstack researcher Rafie Muhammad  said . LiteSpeed Cache , which is used to improve site performance, has more than five million installations. The latest version of the plugin is 6.1, which was released on February 5, 2024. The WordPress security company said CVE-2023-40000 is the result of a lack of user input sanitization and  escaping output .
