Israeli Entities Targeted by Cyberattack Using Donut and Sliver Frameworks

Israeli Entities Targeted by Cyberattack Using Donut and Sliver Frameworks

Jul 03, 2024 Cyber Attack / Malware
Cybersecurity researchers have discovered an attack campaign that targets various Israeli entities with publicly-available frameworks like Donut and Sliver. The campaign, believed to be highly targeted in nature, "leverage target-specific infrastructure and custom WordPress websites as a payload delivery mechanism, but affect a variety of entities across unrelated verticals, and rely on well-known open-source malware," HarfangLab said in a report last week. The French company is tracking the activity under the name Supposed Grasshopper. It's a reference to an attacker-controlled server ("auth.economy-gov-il[.]com/SUPPOSED_GRASSHOPPER.bin"), to which a first-stage downloader connects to. This downloader, written in Nim, is rudimentary and is tasked with downloading the second-stage malware from the staging server. It's delivered by means of a virtual hard disk (VHD) file that's suspected to be propagated via custom WordPress sites as part of a drive-

An unnamed high-profile government organization in Southeast Asia emerged as the target of a "complex, long-running" Chinese state-sponsored cyber espionage operation codenamed Crimson Palace . "The overall goal behind the campaign was to maintain access to the target network for cyberespionage in support of Chinese state interests," Sophos researchers Paul Jaramillo, Morgan Demboski, Sean Gallagher, and Mark Parsons said in a report shared with The Hacker News. "This includes accessing critical IT systems, performing reconnaissance of specific users, collecting sensitive military and technical information, and deploying various malware implants for command-and-control (C2) communications." The name of the government organization was not disclosed, but the company said the country is known to have repeated conflict with China over territory in the South China Sea , raising the possibility that it may be the Philippines, which has been targeted by Chi
Beyond Threat Detection – A Race to Digital Security

Beyond Threat Detection – A Race to Digital Security

May 31, 2024 Threat Detection / Endpoint Security
Digital content is a double-edged sword, providing vast benefits while simultaneously posing significant threats to organizations across the globe. The sharing of digital content has increased significantly in recent years, mainly via email, digital documents, and chat. In turn, this has created an expansive attack surface and has made 'digital content' the preferred carrier for cybercriminals and nation-state threat actors. Digital content is the easy way in for attackers, whether it be to launch sophisticated attacks, malware distribution and phishing or ransomware attacks.  Governments and highly regulated industries are particularly vulnerable due to the notoriety attackers can receive and the "prize" or impact that can come in compromising their networks. For Governments and defense agencies, this could mean losing access to sensitive and classified information. For critical infrastructure and highly regulated industries that could mean disruption to services or physical damage.

Kimsuky APT Deploying Linux Backdoor Gomir in South Korean Cyber Attacks

May 17, 2024 Linux / Malware
The  Kimsuky  (aka Springtail) advanced persistent threat (APT) group, which is linked to North Korea's Reconnaissance General Bureau (RGB), has been observed deploying a Linux version of its GoBear backdoor as part of a campaign targeting South Korean organizations. The backdoor, codenamed  Gomir , is "structurally almost identical to GoBear, with extensive sharing of code between malware variants," the Symantec Threat Hunter Team, part of Broadcom,  said  in a new report. "Any functionality from GoBear that is operating system-dependent is either missing or reimplemented in Gomir." GoBear was  first documented  by South Korean security firm S2W in early February 2024 in connection with a campaign that delivered a malware called Troll Stealer (aka TrollAgent), which overlaps with known Kimsuky malware families like AppleSeed and AlphaSeed. A subsequent analysis by the AhnLab Security Intelligence Center (ASEC) revealed that the malware is distributed via t

North Korean Hackers Deploy New Golang Malware 'Durian' Against Crypto Firms

May 10, 2024 Malware / Cyber Espionage
The North Korean threat actor tracked as Kimsuky has been observed deploying a previously undocumented Golang-based malware dubbed  Durian  as part of highly-targeted cyber attacks aimed at two South Korean cryptocurrency firms. "Durian boasts comprehensive backdoor functionality, enabling the execution of delivered commands, additional file downloads, and exfiltration of files," Kaspersky  said  in its APT trends report for Q1 2024. The attacks, which occurred in August and November 2023, entailed the use of legitimate software exclusive to South Korea as an infection pathway, although the precise mechanism used to manipulate the program is currently unclear. What's known is that the software establishes a connection to the attacker's server, leading to the retrieval of a malicious payload that kicks off the infection sequence. The first-stage serves as an installer for additional malware and a means to establish persistence on the host. It also paves the way fo
