The Hacker News - Most Trusted Cyber Security and Computer Security Analysis: ransomware

The threat actors behind Cuba (aka COLDDRAW) ransomware have received more than $60 million in ransom payments and compromised over 100 entities across the world as of August 2022. In a new advisory shared by the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI), the agencies  highlighted  a "sharp increase in both the number of compromised U.S. entities and the ransom amounts." The ransomware crew, also known as  Tropical Scorpius , has been observed targeting financial services, government facilities, healthcare, critical manufacturing, and IT sectors, while simultaneously expanding its tactics to gain initial access and interact with breached networks. The entry point for the attacks involves the exploitation of known security flaws, phishing, compromised credentials, and legitimate remote desktop protocol (RDP) tools, followed by distributing the ransomware via  Hancitor  (aka Chanitor). It's worth noting

Ukraine has come under a fresh onslaught of ransomware attacks that mirror previous intrusions attributed to the Russia-based Sandworm nation-state group. Slovak cybersecurity company ESET, which dubbed the new ransomware strain  RansomBoggs , said the attacks against several Ukrainian entities were first detected on November 21, 2022. "While the malware written in .NET is new, its deployment is similar to previous attacks attributed to Sandworm," the company  said  in a series of tweets Friday. The development comes as the Sandworm actor, tracked by Microsoft as Iridium, was implicated for a set of attacks aimed at transportation and logistics sectors in Ukraine and Poland with another ransomware strain called  Prestige  in October 2022. The RansomBoggs activity is said to employ a PowerShell script to distribute the ransomware, with the former "almost identical" to the one used in the  Industroyer2 malware  attacks that came to light in April. According to

The operators of the RansomExx ransomware have become the latest to develop a new variant fully rewritten in the Rust programming language, following other strains like  BlackCat ,  Hive , and  Luna . The latest version, dubbed RansomExx2 by the threat actor known as Hive0091 (aka DefrayX), is primarily designed to run on the Linux operating system, although it's expected that a Windows version will be released in the future. RansomExx, also known as Defray777 and Ransom X, is a  ransomware   family  that's known to be active since 2018. It has since been linked to a number of attacks on government agencies, manufacturers, and other high-profile entities like Embraer and GIGABYTE. "Malware written in Rust often benefits from lower [antivirus] detection rates (compared to those written in more common languages) and this may have been the primary reason to use the language," IBM Security X-Force researcher Charlotte Hammond  said  in a report published this week.

Companies based in the U.S. have been at the receiving end of an "aggressive" Qakbot malware campaign that leads to Black Basta ransomware infections on compromised networks. "In this latest campaign, the Black Basta ransomware gang is using QakBot malware to create an initial point of entry and move laterally within an organization's network," Cybereason researchers Joakim Kandefelt and Danielle Frankel  said  in a report shared with The Hacker News. Black Basta, which emerged in April 2022, follows the tried-and-tested approach of double extortion to steal sensitive data from targeted companies and use it as a leverage to extort cryptocurrency payments by threatening to release the stolen information. This is not the first time the ransomware crew has been observed using Qakbot (aka QBot, QuackBot, or Pinkslipbot). Last month, Trend Micro  disclosed  similar attacks that entailed the use of Qakbot to deliver the  Brute Ratel C4  framework, which, in turn,

The cybercrime group called Daixin Team has leaked sample data belonging to AirAsia, a Malaysian low-cost airline, on its data leak portal. The development comes a little over a week after the company fell victim to a ransomware attack on November 11 and 12, per  DataBreaches.net . The threat actors allegedly claim to have obtained the personal data associated with five million unique passengers and all of its employees. The samples uploaded to the leak site reveal passenger information and the booking IDs as well as personal data related to the company's staff. A spokesperson for the threat actor told DataBreaches.net that further attacks were not pursued owing to AirAsia's poor security measures and "the chaotic organization of the network." It's a rare case of a threat actor stopping its attacks against a company as a result of bad security practices. Daixin Team was recently the subject of an  advisory  from the U.S. cybersecurity and intelligence ag

A developing threat activity cluster has been found using Google Ads in one of its campaigns to distribute various post-compromise payloads, including the recently discovered  Royal ransomware . Microsoft, which spotted the updated malware delivery method in late October 2022, is tracking the group under the name  DEV-0569 . "Observed DEV-0569 attacks show a pattern of continuous innovation, with regular incorporation of new discovery techniques, defense evasion, and various post-compromise payloads, alongside increasing ransomware facilitation," the Microsoft Security Threat Intelligence team  said  in an analysis. The threat actor is known to rely on malvertising to point unsuspecting victims to malware downloader links that pose as software installers for legitimate apps like Adobe Flash Player, AnyDesk, LogMeIn, Microsoft Teams, and Zoom. The malware downloader, a strain referred to as  BATLOADER , is a dropper that functions as a conduit to distribute next-stage pa

The U.S. Department of Justice (DoJ) has announced charges against a dual Russian and Canadian national for his alleged participation in  LockBit ransomware attacks  across the world. The 33-year-old Ontario resident,  Mikhail Vasiliev , has been taken into custody and is awaiting extradition to the U.S., where is likely to be sentenced for a maximum of five years in prison. Vasiliev has been charged with conspiracy to intentionally damage protected computers and to transmit ransom demands, according to a  criminal complaint  filed in the District of New Jersey. A search of the defendant's home in August and October 2022 by Canadian law enforcement unearthed a file stored on a device containing what's suspected to be a list of "prospective or historical" victims as well as screenshots of communications exchanged with "LockBitSupp" on the Tox messaging platform. Also found were a text file with instructions to deploy LockBit ransomware, the malware'

Microsoft on Thursday attributed the recent spate of ransomware incidents targeting transportation and logistics sectors in Ukraine and Poland to a threat cluster that shares overlaps with the Russian state-sponsored  Sandworm group . The attacks, which were disclosed by the tech giant last month, involved a strain of previously undocumented malware called  Prestige  and is said to have taken place within an hour of each other across all victims. The Microsoft Threat Intelligence Center (MSTIC) is now tracking the threat actor under its element-themed moniker Iridium (née DEV-0960), a Russia-based group that's publicly tracked by the name Sandworm (aka Iron Viking, TeleBots, and Voodoo Bear). "This attribution assessment is based on forensic artifacts, as well as overlaps in victimology, tradecraft, capabilities, and infrastructure, with known Iridium activity," MSTIC  said  in an update. The company also further assessed the group to have orchestrated compromise act

The Amadey malware is being used to deploy  LockBit 3.0 ransomware  on compromised systems, researchers have warned. "Amadey bot, the malware that is used to install LockBit, is being distributed through two methods: one using a malicious Word document file, and the other using an executable that takes the disguise of the Word file icon," AhnLab Security Emergency Response Center (ASEC)  said  in a new report published today. Amadey, first discovered in 2018, is a "criminal-to-criminal (C2C) botnet infostealer project," as  described  by the BlackBerry Research and Intelligence Team, and is offered for purchase on the criminal underground for as much as $600. While its primary function is to harvest sensitive information from the infected hosts, it further doubles up as a channel to deliver next-stage artifacts. Earlier this July, it was  spread using SmokeLoader , a malware with not-so-different features like itself. Just last month, ASEC also  found  the mal

A new analysis of tools put to use by the Black Basta ransomware operation has identified ties between the threat actor and the  FIN7  (aka Carbanak) group. This link "could suggest either that Black Basta and FIN7 maintain a special relationship or that one or more individuals belong to both groups," cybersecurity firm SentinelOne  said  in a technical write-up shared with The Hacker News. Black Basta, which  emerged  earlier this year, has been attributed to a ransomware spree that has claimed over 90 organizations as of September 2022, suggesting that the adversary is both well-organized and well-resourced. One notable aspect that makes the group stand out, per SentinelOne, is the fact that there have been no signs of its operators attempting to recruit affiliates or advertising the malware as a RaaS on darknet forums or crimeware marketplaces. This has raised the possibility that the Black Basta developers either cut out affiliates from the chain and deploy the ranso

The Raspberry Robin worm is becoming an access-as-a-service malware for deploying other payloads, including  IcedID ,  Bumblebee ,  TrueBot  (aka Silence), and  Clop ransomware . It is "part of a complex and interconnected malware ecosystem, with links to other malware families and alternate infection methods beyond its original USB drive spread," the Microsoft Security Threat Intelligence Center (MSTIC)  said  in a detailed write-up. Raspberry Robin , also called QNAP Worm owing to the use of compromised QNAP storage servers for command-and-control, is the name given to a malware by cybersecurity company Red Canary that spreads to Windows systems through infected USB drives. MSTIC is keeping tabs on the activity group behind the USB-based Raspberry Robin infections as  DEV-0856 , adding it's aware of at least four confirmed entry points that all have the likely end goal of deploying ransomware. The tech giant's cybersecurity team said that Raspberry Robin has

A cybercrime group known as  Vice Society  has been linked to multiple ransomware strains in its malicious campaigns aimed at the education, government, and retail sectors. The Microsoft Security Threat Intelligence team, which is tracking the threat cluster under the moniker DEV-0832, said the group avoids deploying ransomware in some cases and rather likely carries out extortion using exfiltrated stolen data. "Shifting ransomware payloads over time from  BlackCat ,  Quantum Locker , and  Zeppelin , DEV-0832's latest payload is a Zeppelin variant that includes Vice Society-specific file extensions, such as .v-s0ciety, .v-society, and, most recently, .locked," the tech giant's cybersecurity division  said . Vice Society, active since June 2021, has been steadily observed encrypting and exfiltrating victim data, and threatening companies with exposure of siphoned information to pressure them into paying a ransom. "Unlike other RaaS (Ransomware-as-a-Service)

Cisco has warned of active exploitation attempts targeting a pair of two-year-old security flaws in the Cisco AnyConnect Secure Mobility Client for Windows. Tracked as  CVE-2020-3153  (CVSS score: 6.5) and  CVE-2020-3433  (CVSS score: 7.8), the vulnerabilities could enable local authenticated attackers to perform DLL hijacking and copy arbitrary files to system directories with elevated privileges.  While CVE-2020-3153 was addressed by Cisco in February 2020, a fix for CVE-2020-3433 was shipped in August 2020. "In October 2022, the Cisco Product Security Incident Response Team became aware of additional attempted exploitation of this vulnerability in the wild," the networking equipment maker said in an updated advisory. "Cisco continues to strongly recommend that customers upgrade to a fixed software release to remediate this vulnerability." The alert comes as the U.S. Cybersecurity and Infrastructure Security Agency (CISA) moved to add the two flaws to its K

The  Hive  ransomware-as-a-service (RaaS) group has claimed responsibility for a cyber attack against Tata Power that was disclosed by the company less than two weeks ago. The incident is said to have occurred on October 3, 2022. The threat actor has also been observed leaking stolen data exfiltrated prior to encrypting the network as part of its double extortion scheme. This allegedly comprises signed client contracts, agreement documents, as well as other sensitive information such as emails, addresses, phone numbers, passport numbers, taxpayer data, among others. The Mumbai-based firm, which is India's largest integrated power company, is part of the Tata Group conglomerate. Tata Power had previously  disclosed  in a filing with the National Stock Exchange (NSE) of India that an intrusion on the company's IT infrastructure impacted "some of its IT systems." According to  further details  shared by security researcher Rakesh Krishnan, the leak contains person

U.S. cybersecurity and intelligence agencies have published a joint advisory warning of attacks perpetrated by a cybercrime gang known as the  Daixin Team  primarily targeting the healthcare sector in the country. "The Daixin Team is a ransomware and data extortion group that has targeted the HPH Sector with ransomware and data extortion operations since at least June 2022," the agencies  said . The alert was published Friday by the Federal Bureau of Investigation (FBI), Cybersecurity and Infrastructure Security Agency (CISA), and the Department of Health and Human Services (HHS). Over the past four months, the group has been linked to multiple ransomware incidents in the Healthcare and Public Health (HPH) sector, encrypting servers related to electronic health records, diagnostics, imaging, and intranet services. It's also said to have exfiltrated personal identifiable information (PII) and patient health information (PHI) as part of a double extortion scheme to se

The breach of LA Unified School District (LAUSD) highlights the prevalence of password vulnerabilities, as criminal hackers continue to use breached credentials in increasingly frequent ransomware attacks on education. The Labor Day weekend breach of LAUSD brought significant  districtwide disruptions to access to email , computers, and applications. It's unclear what student or employee data the attackers exfiltrated. There is a significant trend in ransomware breaches in education, a highly vulnerable sector. The transitory nature of students leaves accounts and passwords vulnerable. The open environments schools create to foster student exploration and the relative naivete in the sector regarding cybersecurity invite attacks.  The breach at LAUSD and what happened afterward Four days post-breach, reports came that criminals had offered credentials for accounts inside the school district's network  for sale on the dark web  months before the attack. The stolen credential

A Russian-speaking ransomware group dubbed OldGremlin has been attributed to 16 malicious campaigns aimed at entities operating in the transcontinental Eurasian nation over the course of two and a half years. "The group's victims include companies in sectors such as logistics, industry, insurance, retail, real estate, software development, and banking," Group-IB  said  in an exhaustive report shared with The Hacker News. "In 2020, the group even targeted an arms manufacturer." In what's a rarity in the ransomware landscape, OldGremlin (aka TinyScouts) is one of the very few financially motivated cybercrime gangs that primarily focuses on Russian companies. Other notable groups consist of Dharma, Crylock, and Thanos, contributing to an uptick in ransomware attacks targeting businesses in the country by over 200% in 2021. OldGremlin first came to light in September 2020 when the Singapore-headquartered cybersecurity company  disclosed  nine campaigns orch
