Chinese-speaking users are the target of a "highly organized and sophisticated attack" campaign that is likely leveraging phishing emails to infect Windows systems with Cobalt Strike payloads. "The attackers managed to move laterally, establish persistence and remain undetected within the systems for more than two weeks," Securonix researchers Den Iuzvyk and Tim Peck said in a new report. The covert campaign, codenamed SLOW#TEMPEST and not attributed to any known threat actor, commences with malicious ZIP files that, when unpacked, activates the infection chain, leading to the deployment of the post-exploitation toolkit on compromised systems. Present with the ZIP archive is a Windows shortcut (LNK) file that disguises itself as a Microsoft Word file, "违规远程控制软件人员名单.docx.lnk," which roughly translates to "List of people who violated the remote control software regulations." "Given the language used in the lure files, it's likely th

Attackers are increasingly using new phishing toolkits (open-source, commercial, and criminal) to execute adversary-in-the-middle (AitM) attacks. AitM enables attackers to not just harvest credentials but steal live sessions, allowing them to bypass traditional phishing prevention controls such as MFA, EDR, and email content filtering. In this article, we're going to look at what AitM phishing is, how it works, and what organizations need to be able to detect and block these attacks effectively. What is AitM phishing? AitM phishing is a technique that uses dedicated tooling to act as a proxy between the target and a legitimate login portal for an application.  As it's a proxy to the real application, the page will appear exactly as the user expects, because they are logging into the legitimate site – just taking a detour via the attacker's device. For example, if accessing their webmail, the user will see all their real emails; if accessing their cloud file store then all their r

Want to know what's the latest and greatest in SecOps for 2024? Gartner's recently released Hype Cycle for Security Operations report takes important steps to organize and mature the domain of Continuous Threat Exposure Management, aka CTEM. Three categories within this domain are included in this year's report: Threat Exposure Management, Exposure Assessment Platforms (EAP), and Adversarial Exposure Validation (AEV). These category definitions are aimed at providing some structure to the evolving landscape of exposure management technologies. Pentera, listed as a sample vendor in the newly defined AEV category, is playing a pivotal role in increasing the adoption of CTEM, with a focus on security validation. Following is our take on the CTEM related product categories and what they mean for enterprise security leaders. The Industry is Maturing CTEM, coined by Gartner in 2022, presents a structural approach for continuously assessing, prioritizing, validating, and remediating expo

Cybersecurity researchers have uncovered new Android malware that can relay victims' contactless payment data from physical credit and debit cards to an attacker-controlled device with the goal of conducting fraudulent operations. The Slovak cybersecurity company is tracking the novel malware as NGate, stating it observed the crimeware campaign targeting three banks in Czechia. The malware "has the unique ability to relay data from victims' payment cards, via a malicious app installed on their Android devices, to the attacker's rooted Android phone," researchers Lukáš Štefanko and Jakub Osmani said in an analysis. The activity is part of a broader campaign that has been found to target financial institutions in Czechia since November 2023 using malicious progressive web apps (PWAs) and WebAPKs. The first recorded use of NGate was in March 2024. The end goal of the attacks is to clone near-field communication (NFC) data from victims' physical payment ca

Meta Platforms on Friday became the latest company after Microsoft, Google, and OpenAI to expose the activities of an Iranian state-sponsored threat actor, who it said used a set of WhatsApp accounts that attempted to target individuals in Israel, Palestine, Iran, the U.K., and the U.S. The activity cluster, which originated from Iran, "appeared to have focused on political and diplomatic officials, and other public figures, including some associated with administrations of President Biden and former President Trump," Meta said . The social media giant attributed it to a nation-state actor tracked as APT42, which is also known as Charming Kitten, Damselfly, Mint Sandstorm (formerly Phosphorus), TA453, and Yellow Garuda. It's assessed to be linked to Iran's Islamic Revolutionary Guard Corps (IRGC). The adversarial collective is well-known for its use of sophisticated social engineering lures to spear-phish targets of interest with malware and steal their credenti

Russian and Belarusian non-profit organizations, Russian independent media, and international non-governmental organizations active in Eastern Europe have become the target of two separate spear-phishing campaigns orchestrated by threat actors whose interests align with that of the Russian government. While one of the campaigns – dubbed River of Phish – has been attributed to COLDRIVER , an adversarial collective with ties to Russia's Federal Security Service (FSB), the second set of attacks have been deemed the work of a previously undocumented threat cluster codenamed COLDWASTREL. Targets of the campaigns also included prominent Russian opposition figures-in-exile, officials and academics in the US think tank and policy space, and a former U.S. ambassador to Ukraine, according to a joint investigation from Access Now and the Citizen Lab. "Both kinds of attacks were highly tailored to better deceive members of the target organizations," Access Now said . "The m

A previously unknown threat actor has been attributed to a spate of attacks targeting Azerbaijan and Israel with an aim to steal sensitive data. The attack campaign, detected by NSFOCUS on July 1, 2024, leveraged spear-phishing emails to single out Azerbaijani and Israeli diplomats. The activity is being tracked under the moniker Actor240524 . "Actor240524 possesses the ability to steal secrets and modify file data, using a variety of countermeasures to avoid overexposure of attack tactics and techniques," the cybersecurity company said in an analysis published last week. The attack chains commence with the use of phishing emails bearing Microsoft Word documents that, upon opening, urge the recipients to " Enable Content " and run a malicious macro responsible for executing an intermediate loader payload codenamed ABCloader ("MicrosoftWordUpdater.log"). In the next step, ABCloader acts as a conduit to decrypt and load a DLL malware called ABCsync (&

An ongoing social engineering campaign with alleged links to the Black Basta ransomware group has been linked to "multiple intrusion attempts" with the goal of conducting credential theft and deploying a malware dropper called SystemBC. "The initial lure being utilized by the threat actors remains the same: an email bomb followed by an attempt to call impacted users and offer a fake solution," Rapid7 said , adding "external calls were typically made to the impacted users via Microsoft Teams." The attack chain then convinces the user to download and install a legitimate remote access software named AnyDesk, which acts as a channel for deploying follow-on payloads and exfiltrate sensitive data. This includes the use of an executable called "AntiSpam.exe" that purports to download email spam filters and urges users to enter their Windows credentials to complete the update. The step is followed by the execution of several binaries, DLL files,

The North Korea-linked threat actor known as Kimsuky has been linked to a new set of attacks targeting university staff, researchers, and professors for intelligence gathering purposes. Cybersecurity firm Resilience said it identified the activity in late July 2024 after it observed an operation security (OPSEC) error made by the hackers. Kimsuky, also known by the names APT43, ARCHIPELAGO, Black Banshee, Emerald Sleet, Springtail, and Velvet Chollima, is just one of the myriad offensive cyber teams operating under the direction of the North Korean government and military. It's also very active, often leveraging spear-phishing campaigns as a starting point to deliver an ever-expanding set of custom tools to conduct reconnaissance, pilfer data, and establish persistent remote access to infected hosts. The attacks are also characterized by the use of compromised hosts as staging infrastructure to deploy an obfuscated version of the Green Dinosaur web shell, which is then used

Organizations in Kazakhstan are the target of a threat activity cluster dubbed Bloody Wolf that delivers a commodity malware called STRRAT (aka Strigoi Master). "The program selling for as little as $80 on underground resources allows the adversaries to take control of corporate computers and hijack restricted data," cybersecurity vendor BI.ZONE said in a new analysis. The cyber attacks employ phishing emails as an initial access vector, impersonating the Ministry of Finance of the Republic of Kazakhstan and other agencies to trick recipients into opening PDF attachments. The file purports to be a non-compliance notice and contains links to a malicious Java archive (JAR) file as well as an installation guide for the Java interpreter necessary for the malware to function. In an attempt to lend legitimacy to the attack, the second link points to a web page associated with the country's government website that urges visitors to install Java in order to ensure that th

We'll TL;DR the FUDdy introduction: we all know that phishing attacks are on the rise in scale and complexity, that AI is enabling more sophisticated attacks that evade traditional defenses, and the never-ending cybersecurity talent gap means we're all struggling to keep security teams fully staffed.  Given that reality, security teams need to be able to monitor and respond to threats effectively and efficiently. You obviously can't let real threats slip past unnoticed, but you also can't afford to waste time chasing false positives.  In this post, we're going to look at some of the ways Material Security 's unique approach to email security and data protection can dramatically–and quantifiably–save your security teams hours each week while improving the effectiveness of your security program.  What's Your Alert Budget? Before we dive into the "how," let's take a moment to look at why efficiency is critical in security operations. To do that, let's think about how many alerts can

Companies in Russia and Moldova have been the target of a phishing campaign orchestrated by a little-known cyber espionage group known as XDSpy . The findings come from cybersecurity firm F.A.C.C.T., which said the infection chains lead to the deployment of a malware called DSDownloader. The activity was observed this month, it added. XDSpy is a threat actor of indeterminate origin that was first uncovered by the Belarusian Computer Emergency Response Team, CERT.BY, in February 2020. A subsequent analysis by ESET attributed the group to information-stealing attacks aimed at government agencies in Eastern Europe and the Balkans since 2011. Attack chains mounted by the adversary are known to leverage spear-phishing emails in order to infiltrate their targets with a main malware module known as XDDown that, in turn, drops additional plugins for gathering system information, enumerating C: drive, monitoring external drives, exfiltrating local files, and gathering passwords. Ove

A threat actor known as Stargazer Goblin has set up a network of inauthentic GitHub accounts to fuel a Distribution-as-a-Service (DaaS) that propagates a variety of information-stealing malware and netting them $100,000 in illicit profits over the past year. The network, which comprises over 3,000 accounts on the cloud-based code hosting platform, spans thousands of repositories that are used to share malicious links or malware, per Check Point, which has dubbed it "Stargazers Ghost Network." Some of the malware families propagated using this method include Atlantida Stealer, Rhadamanthys, RisePro, Lumma Stealer, and RedLine, with the bogus accounts also engaged in starring, forking, watching, and subscribing to malicious repositories to give them a veneer of legitimacy. The network is believed to have been active since August 2022 in some preliminary form, although an advertisement for the DaaS wasn't spotted in the dark until early July 2023. "Threat actors no

The remote access trojan known as Gh0st RAT has been observed being delivered by an "evasive dropper" called Gh0stGambit as part of a drive-by download scheme targeting Chinese-speaking Windows users. These infections stem from a fake website ("chrome-web[.]com") serving malicious installer packages masquerading as Google's Chrome browser, indicating that users searching for the software on the web are being singled out. Gh0st RAT is a long-standing malware that has been observed in the wild since 2008, manifesting in the form of different variants over the years in campaigns primarily orchestrated by China-nexus cyberespionage groups. Some iterations of the trojan have also been previously deployed by infiltrating poorly-secured MS SQL server instances, using it as a conduit to install the Hidden open-source rootkit. According to cybersecurity firm eSentire, which discovered the latest activity, the targeting of Chinese-speaking users is based on &quo
