The Hacker News - Cybersecurity News and Analysis: Cyber Attack

Cybersecurity researchers have unearthed a fourth new malware strain—designed to spread the malware onto other computers in victims' networks—which was deployed as part of the  SolarWinds supply chain attack  disclosed late last year. Dubbed "Raindrop" by Broadcom-owned Symantec, the malware joins the likes of other malicious implants such as  Sunspot , Sunburst (or Solorigate), and Teardrop that were stealthily delivered to enterprise networks. The latest finding comes amid a continued probe into the breach, suspected to be of  Russian origin , that has claimed a number of U.S. government agencies and private sector companies. "The discovery of Raindrop is a significant step in our investigation of the SolarWinds attacks as it provides further insights into post-compromise activity at organizations of interest to the attackers," Symantec researchers  said . The cybersecurity firm said it discovered only four samples of Raindrop to date that were used to d

An ongoing malware campaign has been found exploiting recently disclosed vulnerabilities in network-attached storage (NAS) devices running on Linux systems to co-opt the machines into an  IRC botnet  for launching distributed denial-of-service (DDoS) attacks and mining Monero cryptocurrency. The attacks deploy a new  malware variant called " FreakOut " by leveraging critical flaws fixed in Laminas Project (formerly Zend Framework) and Liferay Portal as well as an unpatched security weakness in TerraMaster, according to Check Point Research's new analysis published today and shared with The Hacker News. Attributing the malware to be the work of a long-time cybercrime hacker — who goes by the aliases Fl0urite and Freak on HackForums and Pastebin at least since 2015 — the researchers said the flaws —  CVE-2020-28188 ,  CVE-2021-3007 , and  CVE-2020-7961  — were weaponized to inject and execute malicious commands in the server. Regardless of the vulnerabilities exploit

Cybersecurity researchers have  disclosed  a series of attacks by a threat actor of Chinese origin that has targeted organizations in Russia and Hong Kong with malware — including a previously undocumented backdoor. Attributing the campaign to  Winnti  (or APT41), Positive Technologies dated the first attack to May 12, 2020, when the APT used LNK shortcuts to extract and run the malware payload. A second attack detected on May 30 used a malicious RAR archive file consisting of shortcuts to two bait PDF documents that purported to be a curriculum vitae and an IELTS certificate. The shortcuts themselves contain links to pages hosted on Zeplin, a legitimate collaboration tool for designers and developers that are used to fetch the final-stage malware that, in turn, includes a shellcode loader ("svchast.exe") and a backdoor called  Crosswalk  ("3t54dE3r.tmp"). Crosswalk, first documented by FireEye in 2017, is a bare-bones modular backdoor capable of carrying out s

Cybersecurity researchers took the wraps off an ongoing surveillance campaign directed against Colombian government institutions and private companies in the energy and metallurgical industries. In a report published by ESET on Tuesday, the Slovak internet security company said the attacks — dubbed " Operation Spalax " — began in 2020, with the modus operandi sharing some similarities to an APT group targeting the country since at least April 2018, but also different in other ways. The overlaps come in the form of phishing emails, which have similar topics and pretend to come from some of the same entities that were used in a February 2019 operation disclosed by  QiAnXin researchers , and subdomain names used for command-and-control (C2) servers. However, the two campaigns diverge in the attachments used for phishing emails, the remote access trojans (RATs) deployed, and the C2 infrastructure employed to fetch the malware dropped. The attack chain begins with the target

Mimecast said on Tuesday that "a sophisticated threat actor" had compromised a digital certificate it provided to certain customers to securely connect its products to Microsoft 365 (M365) Exchange. The discovery was made after the breach was notified by Microsoft, the London-based company  said in an alert  posted on its website, adding it's reached out to the impacted organizations to remediate the issue. The company didn't elaborate on what type of certificate was compromised, but Mimecast offers  seven different digital certificates  based on the geographical location that must be uploaded to M365 to create a server Connection in Mimecast. "Approximately 10 percent of our customers use this connection," the company said. "Of those that do, there are indications that a low single digit number of our customers' M365 tenants were targeted." Mimecast is a cloud-based email management service for Microsoft Exchange and Microsoft Office 365

Cybersecurity researchers took the wraps off a new spyware operation targeting users in Pakistan that leverages trojanized versions of legitimate Android apps to carry out covert surveillance and espionage. Designed to masquerade apps such as the Pakistan Citizen Porta l, a Muslim prayer-clock app called Pakistan Salat Time , Mobile Packages Pakistan , Registered SIMs Checker , and TPL Insurance , the malicious variants have been found to obfuscate their operations to stealthily download a payload in the form of an Android Dalvik executable (DEX) file. "The DEX payload contains most of the malicious features, which include the ability to covertly exfiltrate sensitive data like the user's contact list and the full contents of SMS messages," Sophos threat researchers Pankaj Kohli and Andrew Brandt said. "The app then sends this information to one of a small number of command-and-control websites hosted on servers located in eastern Europe." Interestingly, t

As the investigation into the SolarWinds supply-chain attack continues, cybersecurity researchers have disclosed a third malware strain that was deployed into the build environment to inject the backdoor into the company's Orion network monitoring platform. Called " Sunspot ," the malignant tool adds to a growing list of previously disclosed malicious software such as Sunburst and Teardrop. "This highly sophisticated and novel code was designed to inject the Sunburst malicious code into the SolarWinds Orion Platform without arousing the suspicion of our software development and build teams," SolarWinds' new CEO Sudhakar Ramakrishna  explained . While  preliminary evidence  found that operators behind the espionage campaign managed to compromise the software build and code signing infrastructure of SolarWinds Orion platform as early as October 2019 to deliver the Sunburst backdoor, the latest findings reveal a new timeline that establishes the first brea

Cybersecurity researchers, for the first time, may have found a potential connection between the backdoor used in  the SolarWinds hack  to a previously known malware strain. In new  research  published by Kaspersky researchers today, the cybersecurity firm said it discovered several features that overlap with another backdoor known as  Kazuar , a .NET-based malware first documented by Palo Alto Networks in 2017. Disclosed early last month, the  espionage campaign  was notable for its scale and stealth, with the attackers leveraging the trust associated with SolarWinds Orion software to infiltrate government agencies and other companies so as to deploy a custom malware codenamed "Sunburst." Shared Features Between Sunburst and Kazuar Attribution for the SolarWinds supply-chain compromise has been difficult in part due to little-to-no clues linking the attack infrastructure to previous campaigns or other well-known threat groups. But Kaspersky's latest analysis of th

A U.S. court on Thursday sentenced a 37-year-old Russian to 12 years in prison for perpetrating an international hacking campaign that resulted in the heist of a trove of personal information from several financial institutions, brokerage firms, financial news publishers, and other American companies. Andrei Tyurin was  charged  with computer intrusion, wire fraud, bank fraud, and illegal online gambling offenses, and for his role in one of the largest thefts of U.S. customer data from a single financial institution in history, which involved the personal information of more than 80 million J.P. Morgan Chase customers. Besides the investment bank, some of the other major targets of the hacks were E*Trade, Scottrade, and the Wall Street Journal. Tyurin, who carried out the extensive hacking from his home in Moscow between 2012 to mid-2015, is believed to have netted over $19 million in criminal proceeds as part of his intrusion schemes. In one such instance of security fraud, Tyu

A North Korean hacking group has been found deploying the RokRat Trojan in a new spear-phishing campaign targeting the South Korean government. Attributing the attack to  APT37  (aka Starcruft, Ricochet Chollima, or Reaper), Malwarebytes said it identified a malicious document last December that, when opened, executes a macro in memory to install the aforementioned remote access tool (RAT). "The file contains an embedded macro that uses a VBA self decoding technique to decode itself within the memory spaces of Microsoft Office without writing to the disk. It then embeds a variant of the RokRat into Notepad," the researchers  noted  in a Wednesday analysis. Believed to be active at least since 2012, the  Reaper APT  is known for its focus on public and private entities primarily in South Korea, such as chemicals, electronics, manufacturing, aerospace, automotive, and healthcare entities. Since then, their victimology has expanded beyond the Korean peninsula to include Ja

The U.S. Department of Justice on Wednesday became the latest government agency in the country to admit its internal network was compromised as part of the SolarWinds supply chain attack. "On December 24, 2020, the Department of Justice's Office of the Chief Information Officer (OCIO) learned of previously unknown malicious activity linked to the global SolarWinds incident that has affected multiple federal agencies and technology contractors, among others," DoJ spokesperson Marc Raimondi said in a short statement. "This activity involved access to the Department's Microsoft Office 365 email environment." Calling it a "major incident," the DoJ said the threat actors who spied on government networks through SolarWinds software potentially accessed about 3% of the Justice Department's email accounts, but added there's no indication they accessed classified systems. The disclosure comes a day after the Federal Bureau of Investigation (FB

Cybesecurity researchers today revealed a new malspam campaign that distributes a remote access Trojan (RAT) by purporting to contain a sex scandal video of U.S. President Donald Trump. The emails, which carry with the subject line "GOOD LOAN OFFER!!," come attached with a Java archive (JAR) file called "TRUMP_SEX_SCANDAL_VIDEO.jar," which, when downloaded, installs Qua or Quaverse RAT ( QRAT ) onto the infiltrated system. "We suspect that the bad guys are attempting to ride the frenzy brought about by the recently concluded Presidential elections since the filename they used on the attachment is totally unrelated to the email's theme," Trustwave's Senior Security Researcher Diana Lopera said in a write-up published today. The latest campaign is a variant of the Windows-based QRAT downloader Trustwave researchers  discovered  in August. The infection chain starts with a spam message containing an embedded attachment or a link pointing to a m

The U.S. government on Tuesday formally pointed fingers at the Russian government for orchestrating the massive  SolarWinds supply chain attack  that came to light early last month. "This work indicates that an Advanced Persistent Threat (APT) actor, likely Russian in origin, is responsible for most or all of the recently discovered, ongoing cyber compromises of both government and non-governmental networks," the Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Security Agency (CISA), the Office of the Director of National Intelligence (ODNI), and the National Security Agency (NSA)  said  in a joint statement. Russia, however,  denied  any involvement in the operation on December 13, stating it "does not conduct offensive operations in the cyber domain." The FBI, CISA, ODNI, and NSA are members of the Cyber Unified Coordination Group (UCG), a newly-formed task force put in place by the White House National Security Council to investig

Cyberattacks targeting healthcare organizations have spiked by 45% since November 2020 as COVID-19 cases continue to increase globally. According to a new report published by Check Point Research today and shared with The Hacker News, this increase has made the sector the most targeted industry by cybercriminals when compared to an overall 22% increase in cyberattacks across all industry sectors worldwide seen during the same time period. The average number of weekly attacks in the healthcare sector reached 626 per organization in November as opposed to 430 the previous month, with attack vectors ranging from ransomware, botnets, remote code execution, and distributed denial-of-service (DDoS) attacks. Ransomware attacks against hospitals also marked their biggest jump, with  Ryuk  and Sodinokibi emerging as the primary ransomware variants employed by various criminal groups. "The usage of Ryuk emphasizes the trend of having more targeted and tailored ransomware attacks rath

Ticketmaster has agreed to pay a $10 million fine after being charged with illegally accessing computer systems of a competitor repeatedly between 2013 and 2015 in an attempt to "cut [the company] off at the knees." A subsidiary of Live Nation, the California-based ticket sales and distribution company used the stolen information to gain an advantage over CrowdSurge — which merged with Songkick in 2015 and later acquired by Warner Music Group (WMG) in 2017 — by hiring a former employee to break into its tools and gain insight into the firm's operations. "Ticketmaster employees repeatedly – and illegally – accessed a competitor's computers without authorization using stolen passwords to unlawfully collect business intelligence,"  said  Acting U.S. Attorney Seth DuCharme. "Further, Ticketmaster's employees brazenly held a division-wide 'summit' at which the stolen passwords were used to access the victim company's computers, as if th

Microsoft on Thursday revealed that the threat actors behind the SolarWinds supply chain attack were able to gain access to a small number of internal accounts and escalate access inside its internal network. The "very sophisticated nation-state actor" used the unauthorized access to view, but not modify, the source code present in its repositories, the company said. "We detected unusual activity with a small number of internal accounts and upon review, we discovered one account had been used to view source code in a number of source code repositories," the Windows maker  disclosed  in an update. "The account did not have permissions to modify any code or engineering systems and our investigation further confirmed no changes were made. These accounts were investigated and remediated." The development is the latest in the far-reaching  espionage saga  that came to light earlier in December following revelations by cybersecurity firm FireEye that attac

Threat actors have been discovered distributing a new credential stealer written in AutoHotkey (AHK) scripting language as part of an ongoing campaign that started early 2020. Customers of financial institutions in the US and Canada are among the primary targets for credential exfiltration, with a specific focus on banks such as Scotiabank, Royal Bank of Canada, HSBC, Alterna Bank, Capital One, Manulife, and EQ Bank. Also included in the list is an Indian banking firm ICICI Bank. AutoHotkey  is an open-source custom scripting language for Microsoft Windows aimed at providing easy hotkeys for macro-creation and software automation that allows users to automate repetitive tasks in any Windows application. The multi-stage infection chain commences with a malware-laced Excel file that's embedded with a Visual Basic for Applications (VBA)  AutoOpen  macro, which is subsequently used to drop and execute the downloader client script ("adb.ahk") via a legitimate portable AHK

An authentication bypass vulnerability in the SolarWinds Orion software may have been leveraged by adversaries as a zero-day to deploy the SUPERNOVA malware in target environments. According to an  advisory  published yesterday by the CERT Coordination Center, the SolarWinds Orion API that's used to interface with all other Orion system monitoring and management products suffers from a security flaw (CVE-2020-10148) that could allow a remote attacker to execute unauthenticated API commands, thus resulting in a compromise of the SolarWinds instance. "The authentication of the API can be bypassed by including specific parameters in the  Request.PathInfo  portion of a URI request to the API, which could allow an attacker to execute unauthenticated API commands," the advisory states. "In particular, if an attacker appends a PathInfo parameter of 'WebResource.adx,' 'ScriptResource.adx,' 'i18n.ashx,' or 'Skipi18n' to a request to a Solar

New evidence amidst the ongoing probe into the  espionage campaign  targeting SolarWinds has uncovered an unsuccessful attempt to compromise cybersecurity firm Crowdstrike and access the company's email. The hacking endeavor was reported to the company by Microsoft's Threat Intelligence Center on December 15, which identified a third-party reseller's Microsoft Azure account to be making "abnormal calls" to Microsoft cloud APIs during a 17-hour period several months ago. The undisclosed affected reseller's Azure account handles Microsoft Office licensing for its Azure customers, including CrowdStrike. Although there was an attempt by unidentified threat actors to read the emails, it was ultimately foiled as the firm does not use Microsoft's Office 365 email service, CrowdStrike  said . The incident comes in the wake of the  supply chain attack  of SolarWinds revealed earlier this month, resulting in the deployment of a covert backdoor (aka "Sunbu

Citrix has issued an emergency advisory warning its customers of a security issue affecting its NetScaler application delivery controller (ADC) devices that attackers are abusing to launch amplified distributed denial-of-service (DDoS) attacks against several targets . "An attacker or bots can overwhelm the Citrix ADC [Datagram Transport Layer Security] network throughput, potentially leading to outbound bandwidth exhaustion," the company  noted . "The effect of this attack appears to be more prominent on connections with limited bandwidth." ADCs are purpose-built  networking appliances  whose function is to improve the performance, security, and availability of applications delivered over the web to end-users. The desktop virtualization and networking service provider said it's monitoring the incident and is continuing to investigate its impact on Citrix ADC, adding "the attack is limited to a small number of customers around the world."
