Charming Kitten, the nation-state actor affiliated with Iran's Islamic Revolutionary Guard Corps (IRGC), has been attributed to a bespoke spear-phishing campaign that delivers an updated version of a fully-featured PowerShell backdoor called POWERSTAR . "There have been improved operational security measures placed in the malware to make it more difficult to analyze and collect intelligence," Volexity researchers Ankur Saini and Charlie Gardner said in a report published this week. The threat actor is something of an expert when it comes to employing social engineering to lure targets, often crafting tailored fake personas on social media platforms and engaging in sustained conversations to build rapport before sending a malicious link. It's also tracked under the names APT35, Cobalt Illusion, Mint Sandstorm (formerly Phosphorus), and Yellow Garuda. Recent intrusions orchestrated by Charming Kitten have made use of other implants such as PowerLess and BellaCiao

The newly discovered Chinese nation-state actor known as Volt Typhoon has been observed to be active in the wild since at least mid-2020, with the hacking crew linked to never-before-seen tradecraft to retain remote access to targets of interest. The findings come from CrowdStrike, which is tracking the adversary under the name  Vanguard Panda . "The adversary consistently employed ManageEngine Self-service Plus exploits to gain initial access, followed by custom web shells for persistent access, and living-off-the-land (LotL) techniques for lateral movement," the cybersecurity company  said . Volt Typhoon, as known as Bronze Silhouette, is a  cyber espionage group  from China that's been linked to network intrusion operations against the U.S government, defense, and other critical infrastructure organizations. "This adversary has been known to leverage credentials and living-off-the-land techniques to remain hidden and move quickly through targeted environments

The Chinese cyber espionage actor known as  Camaro Dragon  has been observed leveraging a new strain of self-propagating malware that spreads through compromised USB drives. "While their primary focus has traditionally been Southeast Asian countries, this latest discovery reveals their global reach and highlights the alarming role USB drives play in spreading malware," Check Point said in new research shared with The Hacker News. The cybersecurity company, which found evidence of USB malware infections in Myanmar, South Korea, Great Britain, India, and Russia, said the findings are the result of a cyber incident that it investigated at an unnamed European hospital in early 2023. The probe found that the entity was not directly targeted by the adversary but rather suffered a breach via an employee's USB drive, which became infected when it was plugged into a colleague's computer at a conference in Asia. "Consequently, upon returning to the healthcare institu

The Russian threat actor known as  Shuckworm  has continued its cyber assault spree against Ukrainian entities in a bid to steal sensitive information from compromised environments. Targets of the recent intrusions, which began in February/March 2023, include security services, military, and government organizations, Symantec  said  in a new report shared with The Hacker News. "In some cases, the Russian group succeeded in staging long-running intrusions, lasting for as long as three months," the cybersecurity company said. "The attackers repeatedly attempted to access and steal sensitive information such as reports about the deaths of Ukrainian service members, reports from enemy engagements and air strikes, arsenal inventory reports, training reports, and more." Shuckworm, also known by the names Aqua Blizzard (formerly Actinium), Armageddon, Gamaredon, Iron Tilden, Primitive Bear, Trident Ursa, UNC530, and Winterflounder, is attributed to the Russia's Fe

The threat actor known as  Asylum Ambuscade  has been observed straddling cybercrime and cyber espionage operations since at least early 2020. "It is a crimeware group that targets bank customers and cryptocurrency traders in various regions, including North America and Europe," ESET  said  in an analysis published Thursday. "Asylum Ambuscade also does espionage against government entities in Europe and Central Asia." Asylum Ambuscade was  first documented  by Proofpoint in March 2022 as a nation-state-sponsored phishing campaign that targeted European governmental entities in an attempt to obtain intelligence on refugee and supply movement in the region. The goal of the attackers, per the Slovak cybersecurity firm, is to siphon confidential information and web email credentials from official government email portals. The attacks start off with a spear-phishing email bearing a malicious Excel spreadsheet attachment that, when opened, either exploits VBA code o

A new custom backdoor dubbed  Stealth Soldier  has been deployed as part of a set of highly-targeted espionage attacks in North Africa. "Stealth Soldier malware is an undocumented backdoor that primarily operates surveillance functions such as file exfiltration, screen and microphone recording, keystroke logging and stealing browser information," cybersecurity company Check Point  said  in a technical report. The ongoing operation is characterized by the use of command-and-control (C&C) servers that mimic sites belonging to the Libyan Ministry of Foreign Affairs. The earliest artifacts associated with the campaign date back to October 2022. The attacks commence with potential targets downloading bogus downloader binaries that are delivered via social engineering attacks. The intermediate payloads act as a conduit for retrieving Stealth Soldier, while simultaneously displaying a decoy empty PDF file. The custom modular implant, which is believed to be used sparingly,

The Computer Emergency Response Team of Ukraine (CERT-UA) has warned of cyber attacks targeting state bodies in the country as part of an espionage campaign. The  intrusion set , attributed to a threat actor tracked by the authority as UAC-0063 since 2021, leverages phishing lures to deploy a variety of malicious tools on infected systems. The origins of the hacking crew are presently unknown. In the attack chain described by the agency, the emails targeted an unspecified ministry and purported to be from the Embassy of Tajikistan in Ukraine. It's suspected that the messages were sent from a previously compromised mailbox. The emails come attached with a Microsoft Word document that, upon enabling macros, launches an encoded VBScript called HATVIBE, which is then used to drop additional malware. This includes a keylogger (LOGPIE), a Python-based backdoor capable of running commands sent from a remote server (CHERRYSPY), and a tool focused on exfiltrating files with specific e

New findings about a hacker group linked to cyber attacks targeting companies in the Russo-Ukrainian conflict area reveal that it may have been around for much longer than previously thought. The threat actor, tracked as  Bad Magic  (aka Red Stinger), has not only been linked to a fresh sophisticated campaign, but also to an activity cluster that first came to light in May 2016. "While the previous targets were primarily located in the Donetsk, Luhansk, and Crimea regions, the scope has now widened to include individuals, diplomatic entities, and research organizations in Western and Central Ukraine," Russian cybersecurity firm Kaspersky  said  in a technical report published last week. The campaign is characterized by the use of a novel modular framework codenamed CloudWizard, which features capabilities to take screenshots, record microphone, log keystrokes, grab passwords, and harvest Gmail inboxes. Bad Magic was  first documented  by the company in March 2023, detail

The U.S. government on Tuesday announced the court-authorized disruption of a global network compromised by an advanced malware strain known as  Snake  wielded by Russia's Federal Security Service (FSB). Snake, dubbed the "most sophisticated cyber espionage tool," is the handiwork of a Russian state-sponsored group called  Turla  (aka Iron Hunter, Secret Blizzard, SUMMIT, Uroburos, Venomous Bear, and Waterbug), which the U.S. government attributes to a unit within Center 16 of the FSB. The threat actor has a  track record  of heavily focusing on entities in Europe, the Commonwealth of Independent States (CIS), and countries affiliated with NATO, with recent activity expanding its footprint to incorporate Middle Eastern nations deemed a threat to countries supported by Russia in the region. "For nearly 20 years, this unit [...] has used versions of the Snake malware to steal sensitive documents from hundreds of computer systems in at least 50 countries, which have

The suspected Pakistan-aligned threat actor known as  SideCopy  has been observed leveraging themes related to the Indian military research organization as part of an ongoing phishing campaign. This involves using a ZIP archive lure pertaining to India's Defence Research and Development Organization ( DRDO ) to deliver a malicious payload capable of harvesting sensitive information, Fortinet FortiGuard Labs  said  in a new report. The cyber espionage group, with  activity  dating back to at least 2019, targets entities that align with Pakistan government interests. It's believed to share overlaps with another Pakistani hacking crew called  Transparent Tribe . SideCopy's use of DRDO-related decoys for malware distribution was previously flagged by  Cyble  and Chinese cybersecurity firm  QiAnXin  in March 2023, and again by  Team Cymru  last month. Interestingly, the same attack chains have been observed to load and execute Action RAT as well as an open source remote ac

Three different threat actors leveraged hundreds of elaborate fictitious personas on Facebook and Instagram to target individuals located in South Asia as part of disparate attacks. "Each of these APTs relied heavily on social engineering to trick people into clicking on malicious links, downloading malware or sharing personal information across the internet," Guy Rosen, chief information security officer at Meta,  said . "This investment in social engineering meant that these threat actors did not have to invest as much on the malware side." The fake accounts, in addition to using traditional lures like women looking for a romantic connection, masqueraded as recruiters, journalists, or military personnel. At least two of the  cyber espionage efforts  entailed the use of low-sophistication malware with reduced capabilities, likely in an attempt to get past  app verification checks  established by Apple and Google.  One of the groups that came under Meta's r

A Chinese state-sponsored hacking outfit has resurfaced with a new campaign targeting government, healthcare, technology, and manufacturing entities based in Taiwan, Thailand, the Philippines, and Fiji after more than six months of no activity. Trend Micro  attributed  the intrusion set to a cyber espionage group it tracks under the name  Earth Longzhi , which is a subgroup within  APT41  (aka HOODOO or Winnti) and shares overlaps with various other clusters known as Earth Baku, SparklingGoblin, and GroupCC. Earth Longzhi was  first documented  by the cybersecurity firm in November 2022, detailing its attacks against various organizations located in East and Southeast Asia as well as Ukraine. Attack chains mounted by the threat actor leverage vulnerable public-facing applications as entry points to deploy the  BEHINDER web shell , and then leverage that access to drop additional payloads, including a new variant of a Cobalt Strike loader called CroxLoader. "This recent campa

A little-known Russian-speaking cyber-espionage group has been linked to a new politically-motivated surveillance campaign targeting high-ranking government officials, telecom services, and public service infrastructures in Tajikistan. The intrusion set, dubbed  Paperbug  by Swiss cybersecurity company PRODAFT, has been attributed to a threat actor known as  Nomadic Octopus  (aka DustSquad). "The types of compromised machines range from individuals' computers to [operational technology] devices," PRODAFT said in a deep dive technical report shared with The Hacker News. "These targets make operation 'Paperbug' intelligence-driven." The ultimate motive behind the attacks is unclear at this stage, but the cybersecurity firm has raised the possibility that it could be the work of opposition forces within the country or, alternatively, an intelligence-gathering mission carried out by Russia or China. Nomadic Octopus first came to light in October 2018 w

The advanced persistent threat (APT) group referred to as  Evasive Panda  has been observed targeting an international non-governmental organization (NGO) in Mainland China with malware delivered via update channels of legitimate applications like Tencent QQ. The attack chains are designed to distribute a Windows installer for MgBot malware, ESET security researcher Facundo Muñoz said in a new report published today. The activity commenced in November 2020 and continued throughout 2021. Evasive Panda, also known as Bronze Highland and Daggerfly, is a Chinese-speaking APT group that has been attributed to a series of  cyber espionage attacks  targeting various entities in China, Hong Kong, and other countries located in East and South Asia since at least late December 2012. The group's hallmark is the use of the custom MgBot modular malware framework, which is capable of receiving additional components on the fly to expand on its intelligence-gathering capabilities. Some of th

The cyber espionage actor tracked as  Blind Eagle  has been linked to a new multi-stage attack chain that leads to the deployment of the NjRAT remote access trojan on compromised systems. "The group is known for using a variety of sophisticated attack techniques, including custom malware, social engineering tactics, and spear-phishing attacks," ThreatMon  said  in a Tuesday report. Blind Eagle, also referred to as APT-C-36, is a suspected Spanish-speaking group that chiefly strikes private and public sector entities in Colombia. Attacks orchestrated by the group have also targeted Ecuador, Chile, and Spain. Infection chains documented by  Check Point  and  BlackBerry  this year have revealed the use of spear-phishing lures to deliver commodity malware families like BitRAT and AsyncRAT, as well as in-memory Python loaders capable of launching a Meterpreter payload. The latest discovery from ThreatMon entails the use of a JavaScript downloader to execute a PowerShell scri

U.K. and U.S. cybersecurity and intelligence agencies have  warned  of Russian nation-state actors exploiting now-patched flaws in networking equipment from Cisco to conduct reconnaissance and deploy malware against select targets. The  intrusions , per the authorities, took place in 2021 and targeted a small number of entities in Europe, U.S. government institutions, and about 250 Ukrainian victims. The activity has been attributed to a threat actor tracked as  APT28 , which is also known as Fancy Bear, Forest Blizzard (formerly Strontium), FROZENLAKE, and Sofacy, and is affiliated with the Russian General Staff Main Intelligence Directorate (GRU). "APT28 has been known to access vulnerable routers by using default and weak SNMP community strings, and by exploiting CVE-2017-6742," the National Cyber Security Centre (NCSC) said. CVE-2017-6742  (CVSS score: 8.8) is part of a set of remote code execution flaws that stem from a  buffer overflow condition  in the Simple Ne

The advanced persistent threat (APT) actor known as Winter Vivern is now targeting officials in Europe and the U.S. as part of an ongoing cyber espionage campaign. "TA473 since at least February 2023 has continuously leveraged an unpatched Zimbra vulnerability in publicly facing webmail portals that allows them to gain access to the email mailboxes of government entities in Europe," Proofpoint  said  in a new report. The enterprise security firm is tracking the activity under its own moniker  TA473  (aka UAC-0114), describing it as an adversarial crew whose operations align with that of Russian and Belarussian geopolitical objectives. What it lacks in sophistication, it makes up for in persistence. In recent months, the group has been linked to attacks targeting  state authorities of Ukraine and Poland  as well as  government officials in India, Lithuania, Slovakia, and the Vatican . The NATO-related intrusion wave entails the exploitation of CVE-2022-27926 (CVSS score:
