Russian Hackers May Have Targeted Ukrainian Telecoms with Upgraded 'AcidPour' Malware

Russian Hackers May Have Targeted Ukrainian Telecoms with Upgraded 'AcidPour' Malware

Mar 22, 2024 Linux / Cyber Warfare
The data wiping malware called  AcidPour  may have been deployed in attacks targeting four telecom providers in Ukraine, new findings from SentinelOne show. The cybersecurity firm also confirmed connections between the malware and AcidRain, tying it to threat activity clusters associated with Russian military intelligence. "AcidPour's expanded capabilities would enable it to better disable embedded devices including networking, IoT, large storage (RAIDs), and possibly ICS devices running Linux x86 distributions," security researchers Juan Andres Guerrero-Saade and Tom Hegel  said . AcidPour is a variant of  AcidRain , a wiper that was used to render Viasat KA-SAT modems operable at the onset of the Russo-Ukrainian war in early 2022 and cripple Ukraine's military communications. It also builds upon the latter's features, while targeting Linux systems running on x86 architecture. AcidRain, on the other hand, is compiled for MIPS architecture. Where AcidRain w

VPNFilter Router Malware Adds 7 New Network Exploitation Modules

Security researchers have discovered even more dangerous capabilities in VPNFilter —the highly sophisticated multi-stage malware that infected 500,000 routers worldwide in May this year, making it much more widespread and sophisticated than earlier. Attributed to Russia's APT 28, also known as 'Fancy Bear,' VPNFilter is a malware platform designed to infect routers and network-attached storage devices from 75 brands including Linksys, MikroTik, Netgear, TP-Link, QNAP, ASUS, D-Link, Huawei, ZTE, Ubiquiti, and UPVEL. In May, when VPNFilter infected half a million routers and NAS devices in 54 countries, the FBI seized a key command-and-control domain used by the malware and asked people to reboot their routers. Initially, it was found that VPNFilter had been built with multiple attack modules that could be deployed to the infected routers to steal website credentials and monitor industrial controls or SCADA systems, such as those used in electric grids, other infr

Making Sense of Operational Technology Attacks: The Past, Present, and Future

Mar 21, 2024Operational Technology / SCADA Security
When you read reports about cyber-attacks affecting operational technology (OT), it's easy to get caught up in the hype and assume every single one is sophisticated. But are OT environments all over the world really besieged by a constant barrage of complex cyber-attacks? Answering that would require breaking down the different types of OT cyber-attacks and then looking back on all the historical attacks to see how those types compare.  The Types of OT Cyber-Attacks Over the past few decades, there has been a growing awareness of the need for improved cybersecurity practices in IT's lesser-known counterpart, OT. In fact, the lines of what constitutes a cyber-attack on OT have never been well defined, and if anything, they have further blurred over time. Therefore, we'd like to begin this post with a discussion around the ways in which cyber-attacks can either target or just simply impact OT, and why it might be important for us to make the distinction going forward.

Destructive and MiTM Capabilities of VPNFilter Malware Revealed

It turns out that the threat of the massive VPNFilter botnet malware that was discovered late last month is beyond what we initially thought. Security researchers from Cisco's Talos cyber intelligence have today uncovered more details about VPNFilter malware, an advanced piece of IoT botnet malware that infected more than 500,000 routers in at least 54 countries, allowing attackers to spy on users, as well as conduct destructive cyber operations. Initially, it was believed that the malware targets routers and network-attached storage from Linksys, MikroTik, NETGEAR, and TP-Link, but a more in-depth analysis conducted by researchers reveals that the VPNFilter also hacks devices manufactured by ASUS, D-Link, Huawei, Ubiquiti, QNAP, UPVEL, and ZTE. "First, we have determined that are being targeted by this actor, including some from vendors that are new to the target list. These new vendors are. New devices were also discovered from Linksys, MikroTik, Netgear, and TP-L

Shortly after Cisco's released its early report on a large-scale hacking campaign that infected over half a million routers and network storage devices worldwide, the United States government announced the takedown of a key internet domain used for the attack. Yesterday we reported about a piece of highly sophisticated IoT botnet malware that infected over 500,000 devices  in 54 countries and likely been designed by Russia-baked state-sponsored group in a possible effort to cause havoc in Ukraine, according to an early report published by Cisco's Talos cyber intelligence unit on Wednesday. Dubbed VPNFilter by the Talos researchers, the malware is a multi-stage, modular platform that targets small and home offices (SOHO) routers and storage devices from Linksys, MikroTik, NETGEAR, and TP-Link, as well as network-access storage (NAS) devices. Meanwhile, the court documents unsealed in Pittsburgh on the same day indicate that the FBI has seized a key web domain communic

More than half a million routers and storage devices in dozens of countries have been infected with a piece of highly sophisticated IoT botnet malware, likely designed by Russia-baked state-sponsored group. Cisco's Talos cyber intelligence unit have discovered an advanced piece of IoT botnet malware, dubbed VPNFilter , that has been designed with versatile capabilities to gather intelligence, interfere with internet communications, as well as conduct destructive cyber attack operations. The malware has already infected over 500,000 devices in at least 54 countries, most of which are small and home offices routers and internet-connected storage devices from Linksys, MikroTik, NETGEAR, and TP-Link. Some network-attached storage (NAS) devices known to have been targeted as well.
