The North Korea-linked  ScarCruft  group has been attributed to a previously undocumented backdoor called Dolphin that the threat actor has used against targets located in its southern counterpart. "The backdoor [...] has a wide range of spying capabilities, including monitoring drives and portable devices and exfiltrating files of interest, keylogging and taking screenshots, and stealing credentials from browsers," ESET researcher Filip Jurčacko  said  in a new report published today. Dolphin is said to be selectively deployed, with the malware using cloud services like Google Drive for data exfiltration as well as command-and-control. The Slovak cybersecurity company said it found the implant deployed as a final-stage payload as part of a watering hole attack in early 2021 directed against a South Korean digital newspaper. The campaign, first uncovered by  Kaspersky  and  Volexity  last year,  entailed  the weaponization of two ...

A previously undocumented Android spyware campaign has been found striking Persian-speaking individuals by masquerading as a seemingly harmless VPN application. Russian cybersecurity firm Kaspersky is tracking the campaign under the moniker  SandStrike . It has not been attributed to any particular threat group. "SandStrike is distributed as a means to access resources about the  Bahá'í religion  that are banned in Iran," the company noted in its  APT trends report  for the third quarter of 2022. While the app is ostensibly designed to provide victims with a VPN connection to bypass the ban, it's also configured to covertly siphon data from the victims' devices, such as call logs, contacts, and even connect to a remote server to fetch additional commands. The booby-trapped VPN service, while fully functional, is said to be distributed via a Telegram channel controlled by the adversary. Links to the channel are also advertised on fabricated social media ac...

Serverless environments, leveraging services such as AWS Lambda, offer incredible benefits in terms of scalability, efficiency, and reduced operational overhead. However, securing these environments is extremely challenging. The core of current serverless security practices often revolves around two key components: log monitoring and static analysis of code or system configuration. But here is the issue with that: 1. Logs Only Tell Part of the Story Logs can track external-facing activities, but they don't provide visibility into the internal execution of functions. For example, if an attacker injects malicious code into a serverless function that doesn't interact with external resources (e.g., external APIs or databases), traditional log-based tools will not detect this intrusion. The attacker may execute unauthorized processes, manipulate files, or escalate privileges—all without triggering log events. 2. Static Misconfiguration Detection is Incomplete Static tools that check ...

Two point-of-sale (PoS) malware variants have been put to use by a threat actor to steal information related to more than 167,000 credit cards from payment terminals. According to Singapore-headquartered cybersecurity company Group-IB, the stolen data dumps could net the operators as much as $3.34 million by selling them on underground forums. While a significant proportion of attacks aimed at gathering payment data rely on  JavaScript sniffers  (aka web skimmers) stealthily inserted on e-commerce websites, PoS malware continues to be an ongoing, if less popular, threat. Just last month, Kaspersky detailed new tactics adopted by a Brazilian threat actor known as  Prilex  to steal money by means of fraudulent transactions. "Almost all PoS malware strains have a similar card dump extraction functionality, but different methods for maintaining persistence on infected devices, data exfiltration and processing," researchers Nikolay Shelekhov and Said Khamchiev ...

Cybercriminals are continuing to prey on users searching for cracked software by directing them to fraudulent websites hosting weaponized installers that deploy malware called  NullMixer  on compromised systems. "When a user extracts and executes NullMixer, it drops a number of malware files to the compromised machine," cybersecurity firm Kaspersky said in a Monday report. "It drops a wide variety of malicious binaries to infect the machine with, such as backdoors, bankers, downloaders, spyware, and many others." Besides siphoning users' credentials, address, credit card data, cryptocurrencies, and even Facebook and Amazon account session cookies, what makes NullMixer insidious is its ability to download dozens of trojans at once, significantly widening the scale of the infections. Attack chains typically start when a user attempts to download cracked software from one of the sites, which leads to a password-protected archive that contains an executable fil...

The North Korean nation-state group Kimusky has been linked to a new set of malicious activities directed against political and diplomatic entities located in its southern counterpart since early 2022. Russian cybersecurity firm Kaspersky codenamed the cluster  GoldDragon , with the infection chains leading to the deployment of Windows malware designed to file lists, user keystrokes, and stored web browser login credentials. Included among the potential victims are South Korean university professors, think tank researchers, and government officials.  Kimsuky , also known as Black Banshee, Thallium, and Velvet Chollima, is the name given to a prolific North Korean advanced persistent threat (APT) group that targets entities globally, but with a primary focus on South Korea, to gain intelligence on various topics of interest to the regime. Known to be operating since 2012, the group has a history of employing social engineering tactics, spear-phishing, and watering hole at...

More than 1.31 million users attempted to install malicious or unwanted web browser extensions at least once, new findings from cybersecurity firm Kaspersky show. "From January 2020 to June 2022, more than 4.3 million unique users were attacked by adware hiding in browser extensions, which is approximately 70% of all users affected by malicious and unwanted add-ons," the company  said . As many as 1,311,557 users fall under this category in the first half of 2022, per Kaspersky's telemetry data. In comparison, the number of such users peaked in 2020 at 3,660,236, followed by 1,823,263 unique users in 2021. The most prevalent threat is a family of adware called WebSearch, which masquerade as PDF viewers and other utilities, and comes with capabilities to collect and analyze search queries and redirect users to affiliate links. WebSearch is also notable for modifying the browser's start page, which contains a search engine and a number of links to third-party sour...

The first ever incident possibly involving the ransomware family known as Maui occurred on April 15, 2021, aimed at an unnamed Japanese housing company. The disclosure from Kaspersky arrives a month after U.S. cybersecurity and intelligence agencies issued an  advisory  about the use of the ransomware strain by North Korean government-backed hackers to target the healthcare sector since at least May 2021. Much of the data about its modus operandi came from incident response activities and industry analysis of a Maui sample that revealed a lack of "several key features" typically associated with ransomware-as-a-service (RaaS) operations. Not only is Maui designed to be manually executed by a remote actor via a command-line interface, it's also notable for not including a ransom note to provide recovery instructions. Subsequently, the Justice Department  announced  the seizure of $500,000 worth of Bitcoin that were extorted from several organizations, including t...

Over a dozen military-industrial complex enterprises and public institutions in Afghanistan and Europe have come under a wave of targeted attacks since January 2022 to steal confidential data by simultaneously making use of six different backdoors. Russian cybersecurity firm Kaspersky  attributed  the attacks "with a high degree of confidence" to a China-linked threat actor tracked by  Proofpoint  as  TA428 , citing overlaps in tactics, techniques, and procedures (TTPs).  TA428, also known by the names Bronze Dudley, Temp.Hex, and Vicious Panda, has a  history  of striking entities in Ukraine, Russia, Belarus, and Mongolia. It's believed to share connections with another hacking group called Mustang Panda (aka Bronze President). Targets of the latest cyber espionage campaign included industrial plants, design bureaus and research institutes, government agencies, ministries and departments in several East European countries and Afghanistan. A...

Threat actors are increasingly abusing Internet Information Services ( IIS ) extensions to backdoor servers as a means of establishing a "durable persistence mechanism." That's according to a  new warning  from the Microsoft 365 Defender Research Team, which said that "IIS backdoors are also harder to detect since they mostly reside in the same directories as legitimate modules used by target applications, and they follow the same code structure as clean modules." Attack chains taking this approach commence with weaponizing a critical vulnerability in the hosted application for initial access, using this foothold to drop a script web shell as the first stage payload. This web shell then becomes the conduit for installing a rogue IIS module to provide highly covert and persistent access to the server, in addition to monitoring incoming and outgoing requests as well as running remote commands. Indeed, earlier this month, Kaspersky researchers disclosed a cam...

Kaspersky security researchers have disclosed details of a brand-new ransomware family written in Rust, making it the third strain after  BlackCat  and  Hive  to use the programming language. Luna, as it's called, is "fairly simple" and can run on Windows, Linux, and ESXi systems, with the malware banking on a combination of  Curve25519  and  AES  for encryption. "Both the Linux and ESXi samples are compiled using the same source code with some minor changes from the Windows version," the Russian firm  noted  in a report published today. Advertisements for Luna on darknet forums suggest that the ransomware is intended for use only by Russian-speaking affiliates. Its core developers are also believed to be of Russian origin owing to spelling mistakes in the ransom note hard-coded within the binary. "Luna confirms the trend for cross-platform ransomware," the researchers stated, adding how the platform agnostic nature of languages li...

An advanced persistent threat (APT) actor codenamed ToddyCat has been linked to a string of attacks aimed at government and military entities in Europe and Asia since at least December 2020. The relatively new adversarial collective is said to have commenced its operations by targeting Microsoft Exchange servers in Taiwan and Vietnam using an unknown exploit to deploy the China Chopper web shell and activate a multi-stage infection chain. Other prominent countries singled out include Afghanistan, India, Indonesia, Iran, Kyrgyzstan, Malaysia, Pakistan, Russia, Slovakia, Thailand, the U.K., and Uzbekistan, the swift escalation in targeting marked by improvements to its toolset over the course of successive campaigns. "The first wave of attacks exclusively targeted Microsoft Exchange Servers, which were compromised with Samurai, a sophisticated passive backdoor that usually works on ports 80 and 443," Russian cybersecurity company Kaspersky  said  in a report published toda...

A new set of trojanized apps spread via the Google Play Store has been observed distributing the notorious Joker malware on compromised Android devices. Joker, a  repeat   offender , refers to a class of harmful apps that are used for billing and SMS fraud, while also performing a number of actions of a malicious hacker's choice, such as stealing text messages, contact lists, and device information. Despite continued attempts on the part of Google to scale up its defenses, the apps have been continually iterated to search for gaps and slip into the app store undetected. "They're usually spread on Google Play, where scammers download legitimate apps from the store, add malicious code to them and re-upload them to the store under a different name," Kaspersky researcher Igor Golovin  said  in a report published last week. The trojanized apps, taking the place of their removed counterparts, often appear as messaging, health tracking, and PDF scanner apps that, once...

Russian cybersecurity firm Kaspersky on Tuesday responded to an advisory released by Germany's Federal Office of Information Security (BSI) against using the company's security solutions in the country over "doubts about the reliability of the manufacturer." Calling that the decision was made on "political grounds," the company  said  it will "continue to assure our partners and customers of the quality and integrity of our products, and we will be working with the BSI for clarification on its decision and for the means to address its and other regulators' concerns." The statement from Kaspersky follows a warning from Germany's cybersecurity authority, the Bundesamt für Sicherheit in der Informationstechnik aka BSI, which recommended "replacing applications from Kaspersky's portfolio of antivirus software with alternative products" due to risks that they could be exploited by Russia for a cyber attack. "Companies and...

In this digital era, the success of almost every marketing, advertising, and analytics company drives through tracking users across the Internet to identify them and learn their interests to provide targeted ads. Most of these solutions rely on 3rd-party cookies, a cookie set on a domain other than the one you are browsing, which allows companies including Google and Facebook to fingerprint you in order to track your every move across multiple sites. However, if you're using Kaspersky Antivirus, a vulnerability in the security software had exposed a unique identifier associated with you to every website you visited in the past 4 years, which might have allowed those sites and other third-party services to track you across the web even if you have blocked or erased third-party cookies timely. The vulnerability, identified as CVE-2019-8286 and discovered by independent security researcher Ronald Eikenberg, resides in the way a URL scanning module integrated into the antivir...

Remember " The Shadow Brokers " and the arrest of a former NSA contractor accused of stealing 50 Terabytes of top secret documents from the intelligence agency? It turns out that, Kaspersky Lab, which has been banned in US government computers over spying fears, was the one who tipped off the U.S. government and helped the FBI catch NSA contractor Harold T. Martin III , unnamed sources familiar with the investigation told Politico. In October 2016, the U.S. government arrested and charged Martin, 51, with theft of highly classified documents, including most sensitive NSA hacking tools and top-secret information about "national defense," that he siphoned from government computers over the period of two decades. The breach is believed to be the largest heist of classified government material in America's history, far bigger than Edward Snowden leaks . According to the sources, the Antivirus firm learned about Martin after he sent unusual direct messag...

Moscow-based cyber security firm Kaspersky Lab has taken the United States government to a U.S. federal court for its decision to ban the use of Kaspersky products in federal agencies and departments. In September 2017, the United States Department of Homeland Security (DHS) issued a Binding Operational Directive (BOD) ordering civilian government agencies to remove Kaspersky Lab software from their computers and networks within 90 days. The order came amid mounting concern among United States officials that the Kaspersky antivirus software could be helping Russian government spy on their activities, which may threaten the U.S. national security. U.S. President Donald Trump also signed into law last week legislation that bans the use of Kaspersky products within the U.S. government, capping a months-long effort to purge Kaspersky from federal agencies amid concerns it's vulnerable to Kremlin influence. The Kaspersky's appeal is part of an ongoing campaign by the c...

A former employee—who worked for an elite hacking group operated by the U.S. National Security Agency—pleaded guilty on Friday to illegally taking classified documents home , which were later stolen by Russian hackers. In a press release published Friday, the US Justice Department announced that Nghia Hoang Pho , a 67-year-old of Ellicott City, Maryland, took documents that contained top-secret national information from the agency between 2010 and 2015. Pho, who worked as a developer for the Tailored Access Operations (TAO) hacking group at the NSA, reportedly moved the stolen classified documents and tools to his personal Windows computer at home, which was running Kaspersky Lab software. According to authorities, the Kaspersky Labs' antivirus software was allegedly used, one way or another, by Russian hackers to steal top-secret NSA documents and hacking exploits from Pho's home PC in 2015. "Beginning in 2010 and continuing through March 2015, Pho removed an...

Refuting allegations that its anti-virus product helped Russian spies steal classified files from an NSA employee's laptop, Kaspersky Lab has released more findings that suggest the computer in question may have been infected with malware. Moscow-based cyber security firm Kaspersky Lab on Thursday published the results of its own internal investigation claiming the NSA worker who took classified documents home had a personal home computer overwhelmed with malware. According to the latest Kaspersky report, the telemetry data its antivirus collected from the NSA staffer's home computer contained large amounts of malware files which acted as a backdoor to the PC. The report also provided more details about the malicious backdoor that infected the NSA worker's computer when he installed a pirated version of Microsoft Office 2013 .ISO containing the Mokes backdoor, also known as Smoke Loader. Backdoor On NSA Worker's PC May Have Helped Other Hackers Steal Classi...
