Russian hackers start targeting Ukraine with Follina exploits

By Bill Toulas, Bleeping Computer

Ukraine's Computer Emergency Response Team (CERT) is warning that the Russian hacking group Sandworm may be exploiting Follina, a remote code execution vulnerability in Microsoft Windows Support Diagnostic Tool (MSDT) currently tracked as CVE-2022-30190.

The security issue can be triggered by either opening or selecting a specially crafted document and threat actors have been exploiting it in attacks since at least April 2022.

It is worth noting that Ukraine's agency assesses with medium confidence that behind the malicious activity is the Sandworm hacker group.

By Sergiu Gatlan,  Bleeping Computer Today, the FBI, CISA, and the Department of Health and Human Services (HHS) warned U.S. healthcare organizations of targeted ALPHV/Blackcat ransomware attacks. "ALPHV Blackcat affiliates have been observed primarily targeting the healthcare sector," the joint advisory cautions. Today's warning follows an April 2022 FBI flash alert and another advisory issued in December 2023 detailing the BlackCat cybercrime gang's activity since it surfaced in November 2021 as a suspected rebrand of the DarkSide and BlackMatter ransomware groups. The FBI linked BlackCat to over 60 breaches during its first four months of activity (between November 2021 and March 2022) and said the gang has raked in at least $300 million in ransoms from over 1,000 victims until September 2023. "Since mid-December 2023, of the nearly 70 leaked victims, the healthcare sector has been the most commonly victimized," the three federal agencies warned in today...

Why Your VPN May Not Be As Secure As It Claims

Image
By Krebs On Security Virtual private networking (VPN) companies market their services as a way to prevent anyone from snooping on your Internet usage. But new research suggests this is a dangerous assumption when connecting to a VPN via an untrusted network, because attackers on the same network could force a target’s traffic off of the protection provided by their VPN without triggering any alerts to the user. When a device initially tries to connect to a network, it broadcasts a message to the entire local network stating that it is requesting an Internet address. Normally, the only system on the network that notices this request and replies is the router responsible for managing the network to which the user is trying to connect. The machine on a network responsible for fielding these requests is called a Dynamic Host Configuration Protocol (DHCP) server, which will issue time-based leases for IP addresses. The DHCP server also takes care of setting a specific local address — known ...
