An Iranian state-sponsored threat group has been attributed to a long-term cyber intrusion aimed at a critical national infrastructure (CNI) in the Middle East that lasted nearly two years. The activity, which lasted from at least May 2023 to February 2025, entailed "extensive espionage operations and suspected network prepositioning – a tactic often used to maintain persistent access for future strategic advantage," the FortiGuard Incident Response (FGIR) team said in a report. The network security company noted that the attack exhibits tradecraft overlaps with a known Iranian nation-state threat actor called Lemon Sandstorm (formerly Rubidium), which is also tracked as Parisite, Pioneer Kitten, and UNC757. It's been assessed to be active since at least 2017, striking aerospace, oil and gas, water, and electric sectors across the United States, the Middle East, Europe, and Australia. According to industrial cybersecurity company Dragos, the adversary has leveraged ...

A previously unknown threat actor has been observed copying the tradecraft associated with the Kremlin-aligned Gamaredon hacking group in its cyber attacks targeting Russian-speaking entities. The campaign has been attributed to a threat cluster dubbed GamaCopy , which is assessed to share overlaps with another hacking group named Core Werewolf , also tracked as Awaken Likho and PseudoGamaredon. According to the Knownsec 404 Advanced Threat Intelligence team, the attacks leverage content related to military facilities as lures to drop UltraVNC, allowing threat actors to remotely access the compromised hosts. "The TTP (Tactics, Techniques, and Procedures) of this organization imitates that of the Gamaredon organization which conducts attacks against Ukraine," the company said in a report published last week. The disclosure arrives nearly four months after Kaspersky revealed that Russian government agencies and industrial entities have been the target of Core Werewolf, ...

The Computer Emergency Response Team of Ukraine (CERT-UA) is warning of ongoing attempts by unknown threat actors to impersonate the cybersecurity agency by sending AnyDesk connection requests. The AnyDesk requests claim to be for conducting an audit to assess the "level of security," CERT-UA added, cautioning organizations to be on the lookout for such social engineering attempts that seek to exploit user trust. "It is important to note that CERT-UA may, under certain circumstances, use remote access software such as AnyDesk," CERT-UA said . "However, such actions are taken only after prior agreement with the owners of objects of cyber defense through officially approved communication channels." However, for this attack to succeed, it's necessary that the AnyDesk remote access software is installed and operational on the target's computer. It also requires the attacker to be in possession of the target's AnyDesk identifier , suggesting th...

Not every security vulnerability is high risk on its own - but in the hands of an advanced attacker, even small weaknesses can escalate into major breaches. These five real vulnerabilities, uncovered by Intruder's bug-hunting team, reveal how attackers turn overlooked flaws into serious security incidents. 1. Stealing AWS Credentials with a Redirect Server-Side Request Forgery (SSRF) is a common vulnerability that can have a significant impact, especially in cloud-hosted applications. If a web application fetches resources from user-supplied URLs, care should be taken to ensure attackers can't manipulate requests to access unintended resources. While assessing a home-moving app running in AWS, our team tested common SSRF bypass techniques. The attack chain was as follows: the app sent a webhook request to the attacker's web server, which responded with a 302 redirect to AWS's metadata service. The app followed the redirect and logged the response, which exposed sensitive metadat...

The Russian threat actor known as Star Blizzard has been linked to a new spear-phishing campaign that targets victims' WhatsApp accounts, signaling a departure from its longstanding tradecraft in a likely attempt to evade detection. "Star Blizzard's targets are most commonly related to government or diplomacy (both incumbent and former position holders), defense policy or international relations researchers whose work touches on Russia, and sources of assistance to Ukraine related to the war with Russia," the Microsoft Threat Intelligence team said in a report  shared with The Hacker News. Star Blizzard (formerly SEABORGIUM) is a Russia-linked threat activity cluster known for its credential harvesting campaigns. Active since at least 2012, it's also tracked under the monikers Blue Callisto, BlueCharlie (or TAG-53), Calisto (alternately spelled Callisto), COLDRIVER, Dancing Salome, Gossamer Bear, Iron Frontier, TA446, and UNC4057. Previously observed attack ...

The Russia-linked APT29 threat actor has been observed repurposing a legitimate red teaming attack methodology as part of cyber attacks leveraging malicious Remote Desktop Protocol (RDP) configuration files. The activity, which has targeted governments and armed forces, think tanks, academic researchers, and Ukrainian entities, entails adopting a "rogue RDP" technique that was previously documented by Black Hills Information Security in 2022, Trend Micro said in a report. "A victim of this technique would give partial control of their machine to the attacker, potentially leading to data leakage and malware installation," researchers Feike Hacquebord and Stephen Hilt said . The cybersecurity company is tracking the threat group under its own moniker Earth Koshchei, stating preparations for the campaign began as early as August 7-8, 2024. The RDP campaigns were also spotlighted by the Computer Emergency Response Team of Ukraine (CERT-UA), Microsoft, and Amazon ...

The threat actor known as Gamaredon has been observed leveraging Cloudflare Tunnels as a tactic to conceal its staging infrastructure hosting a malware called GammaDrop. The activity is part of an ongoing spear-phishing campaign targeting Ukrainian entities since at least early 2024 that's designed to drop the Visual Basic Script malware, Recorded Future's Insikt Group said in a new analysis. The cybersecurity company is tracking the threat actor under the name BlueAlpha, which is also known as Aqua Blizzard, Armageddon, Hive0051, Iron Tilden, Primitive Bear, Shuckworm, Trident Ursa, UAC-0010, UNC530, and Winterflounder. The group, believed to be active since 2014, is affiliated with Russia's Federal Security Service (FSB). "BlueAlpha has recently started using Cloudflare Tunnels to conceal staging infrastructure used by GammaDrop , an increasingly popular technique used by cybercriminal threat groups to deploy malware," Insikt Group noted . "BlueAl...

The China-linked threat actor known as MirrorFace has been attributed to a new spear-phishing campaign mainly targeting individuals and organizations in Japan since June 2024. The aim of the campaign is to deliver backdoors known as NOOPDOOR (aka HiddenFace) and ANEL (aka UPPERCUT), Trend Micro said in a technical analysis. "An interesting aspect of this campaign is the comeback of a backdoor dubbed ANEL, which was used in campaigns targeting Japan by APT10 until around 2018 and had not been observed since then," security researcher Hara Hiroaki said . It's worth noting that MirrorFace's use of ANEL was also documented by ESET last month as part of a cyber attack targeting a diplomatic organization in the European Union using lures related to the World Expo. MirrorFace, also known as Earth Kasha, is the name given to a Chinese threat actor that's known for its persistent targeting of Japanese entities. It's assessed to be a sub-cluster within APT10. ...

A new spear-phishing campaign targeting Brazil has been found delivering a banking malware called Astaroth (aka Guildma) by making use of obfuscated JavaScript to slip past security guardrails. "The spear-phishing campaign's impact has targeted various industries, with manufacturing companies, retail firms, and government agencies being the most affected," Trend Micro said in a new analysis. "The malicious emails often impersonate official tax documents, using the urgency of personal income tax filings to trick users into downloading the malware." The cybersecurity company is tracking the threat activity cluster under the name Water Makara. It's worth pointing out that Google's Threat Analysis Group (TAG) has assigned the moniker PINEAPPLE to a similar intrusion set that delivers the same malware to Brazilian users. Both these campaigns share a point of commonality in that they commence with phishing messages that impersonate official entities su...

The Russian GRU-backed threat actor APT28 has been attributed as behind a series of campaigns targeting networks across Europe with the HeadLace malware and credential-harvesting web pages. APT28, also known by the names BlueDelta, Fancy Bear, Forest Blizzard, FROZENLAKE, Iron Twilight, ITG05, Pawn Storm, Sednit, Sofacy, and TA422, is an advanced persistent threat (APT) group affiliated with Russia's strategic military intelligence unit, the GRU. The hacking crew operates with a high level of stealth and sophistication, often demonstrating their adaptability through deep preparedness and custom tooling, and relying on legitimate internet services (LIS) and living off-the-land binaries (LOLBins) to conceal their operations within regular network traffic. "From April to December 2023, BlueDelta deployed Headlace malware in three distinct phases using geofencing techniques to target networks throughout Europe with a heavy focus on Ukraine," Recorded Future's Insikt ...

The infamous cybercrime syndicate known as FIN7 has been linked to a spear-phishing campaign targeting the U.S. automotive industry to deliver a known backdoor called Carbanak (aka Anunak). "FIN7 identified employees at the company who worked in the IT department and had higher levels of administrative rights," the BlackBerry research and intelligence team  said  in a new write-up. "They used the lure of a free IP scanning tool to run their well-known Anunak backdoor and gain an initial foothold utilizing living off the land binaries, scripts, and libraries ( LOLBAS )." FIN7, also known as Carbon Spider, Elbrus, Gold Niagara, ITG14, and Sangria Tempest, is a well-known  financially motivated e-crime group  that has a track record of striking a wide range of industry verticals to deliver malware capable of stealing information from point-of-sale (PoS) systems since 2012. In recent years, the threat actor has  transitioned  to  conducting ransomwar...

The Russia-linked threat actor known as  APT28  has been linked to multiple ongoing phishing campaigns that employ lure documents imitating government and non-governmental organizations (NGOs) in Europe, the South Caucasus, Central Asia, and North and South America. "The uncovered lures include a mixture of internal and publicly available documents, as well as possible actor-generated documents associated with finance, critical infrastructure, executive engagements, cyber security, maritime security, healthcare, business, and defense industrial production," IBM X-Force  said  in a report published last week. The tech company is tracking the activity under the moniker  ITG05 , which is also known as Blue Athena, BlueDelta, Fancy Bear, Fighting Ursa, Forest Blizzard (formerly Strontium), FROZENLAKE, Iron Twilight, Pawn Storm, Sednit, Sofacy, TA422, and UAC-028. The disclosure comes more than three months after the adversary was spotted using decoys related to...

A new phishing campaign is leveraging decoy Microsoft Word documents as bait to deliver a backdoor written in the  Nim programming language . "Malware written in uncommon programming languages puts the security community at a disadvantage as researchers and reverse engineers' unfamiliarity can hamper their investigation," Netskope researchers Ghanashyam Satpathy and Jan Michael Alcantara  said . Nim-based malware has been a rarity in the threat landscape, although that has been slowly changing in recent years as attackers continue to either develop custom tools from scratch using the language or port existing versions of their nefarious programs to it. This has been demonstrated in the case of loaders such as  NimzaLoader ,  Nimbda ,  IceXLoader , as well as ransomware families tracked under the names  Dark Power  and  Kanti . The attack chain documented by Netskope begins with a phishing email containing a Word document attachment that, when...

The North Korean threat actor known as  Kimsuky  has been observed targeting research institutes in South Korea as part of a spear-phishing campaign with the ultimate goal of distributing backdoors on compromised systems. "The threat actor ultimately uses a backdoor to steal information and execute commands," the AhnLab Security Emergency Response Center (ASEC)  said  in an analysis posted last week. The attack chains commence with an import declaration lure that's actually a malicious JSE file containing an obfuscated PowerShell script, a Base64-encoded payload, and a decoy PDF document. The next stage entails opening the PDF file as a diversionary tactic, while the PowerShell script is executed in the background to launch the backdoor. The malware, for its part, is configured to collect network information and other relevant data (i.e., host name, user name, and operating system version) and transmit the encoded details to a remote server. It's also capable o...

The threat actor known as COLDRIVER has continued to engage in credential theft activities against entities that are of strategic interests to Russia while simultaneously improving its detection evasion capabilities. The Microsoft Threat Intelligence team is tracking under the cluster as  Star Blizzard  (formerly SEABORGIUM). It's also called Blue Callisto, BlueCharlie (or TAG-53), Calisto (alternately spelled Callisto), Gossamer Bear, and TA446. The adversary "continues to prolifically target individuals and organizations involved in international affairs, defense, and logistics support to Ukraine, as well as academia, information security companies, and other entities aligning with Russian state interests," Redmond  said . Star Blizzard , linked to Russia's Federal Security Service (FSB), has a  track record  of setting up lookalike domains that impersonate the login pages of targeted companies. It's known to be active since at least 2017. In August 2023...

The Iranian nation-state actor known as  MuddyWater  has been linked to a new spear-phishing campaign targeting two Israeli entities to ultimately deploy a legitimate remote administration tool from N-able called  Advanced Monitoring Agent . Cybersecurity firm Deep Instinct, which disclosed details of the attacks,  said  the campaign "exhibits updated TTPs to previously reported MuddyWater activity," which has, in the past, used similar attack chains to distribute other remote access tools like  ScreenConnect, RemoteUtilities, Syncro , and  SimpleHelp . While the latest development marks the first time MuddyWater has been observed using N-able's remote monitoring software, it also underscores the fact that the largely unchanged modus operandi continues to yield some level of success for the threat actor. The findings have also been separately confirmed by cybersecurity company Group-IB in a post shared on X (formerly Twitter). The state-sponsore...
