More than 225,000 logs containing compromised OpenAI ChatGPT credentials were made available for sale on underground markets between January and October 2023, new findings from Group-IB show. These credentials were found within  information stealer logs  associated with LummaC2, Raccoon, and RedLine stealer malware. "The number of infected devices decreased slightly in mid- and late summer but grew significantly between August and September," the Singapore-headquartered cybersecurity company  said  in its Hi-Tech Crime Trends 2023/2024 report published last week. Between June and October 2023, more than 130,000 unique hosts with access to OpenAI ChatGPT were infiltrated, a 36% increase over what was observed during the first five months of 2023. The breakdown by the top three stealer families is below - LummaC2 - 70,484 hosts Raccoon - 22,468 hosts RedLine - 15,970 hosts "The sharp increase in the number of ChatGPT credentials for sale is due to the overal...

Facebook advertisers in Vietnam are the target of a previously unknown information stealer dubbed  VietCredCare  at least since August 2022. The malware is "notable for its ability to automatically filter out Facebook session cookies and credentials stolen from compromised devices, and assess whether these accounts manage business profiles and if they maintain a positive Meta ad credit balance," Singapore-headquartered Group-IB  said  in a new report shared with The Hacker News. The end goal of the large-scale malware distribution scheme is to facilitate the takeover of corporate Facebook accounts by targeting Vietnamese individuals who manage the Facebook profiles of prominent businesses and organizations. Facebook accounts that have been successfully seized are then used by the threat actors behind the operation to post political content or to propagate phishing and affiliate scams for financial gain. VietCredCare is offered to other aspiring cybercriminals u...

CrowdStrike is named a Leader in the 2024 Gartner® Magic Quadrant™ for Endpoint Protection Platforms for the fifth consecutive time, positioned highest on Ability to Execute and furthest to the right on Completeness of Vision.

An INTERPOL-led collaborative operation targeting phishing, banking malware, and ransomware attacks has led to the identification of 1,300 suspicious IP addresses and URLs. The  law enforcement effort , codenamed  Synergia , took place between September and November 2023 in an attempt to blunt the "growth, escalation and professionalization of transnational cybercrime." Involving 60 law enforcement agencies spanning 55 member countries, the exercise paved the way for the detection of more than 1,300 malicious servers, 70% of which have already been taken down in Europe. Hong Kong and Singapore authorities took down 153 and 86 servers, respectively. Servers, as well as electronic devices, were confiscated following over 30 house searches. Seventy suspects have been identified to date, and 31 from Europe, South Sudan, and Zimbabwe have been arrested. Singapore-headquartered Group-IB, which also contributed to the operation,  said  it identified "more than 500 IP ...

The operators behind the now-defunct  Inferno Drainer  created more than 16,000 unique malicious domains over a span of one year between 2022 and 2023. The scheme "leveraged high-quality phishing pages to lure unsuspecting users into connecting their cryptocurrency wallets with the attackers' infrastructure that spoofed Web3 protocols to trick victims into authorizing transactions," Singapore-headquartered Group-IB  said  in a report shared with The Hacker News. Inferno Drainer, which was active from  November 2022 to November 2023 , is estimated to have reaped over  $87 million in illicit profits  by scamming more than 137,000 victims. The malware is part of a broader set of similar offerings that are available to affiliates under the scam-as-a-service (or drainer-as-a-service) model in exchange for a 20% cut of their earnings. What's more, customers of Inferno Drainer could either upload the malware to their own phishing sites, or make use of t...

A previously unknown hacker outfit called  GambleForce  has been attributed to a series of SQL injection attacks against companies primarily in the Asia-Pacific (APAC) region since at least September 2023. "GambleForce uses a set of basic yet very effective techniques, including SQL injections and the exploitation of vulnerable website content management systems (CMS) to steal sensitive information, such as user credentials," Singapore-headquartered Group-IB  said  in a report shared with The Hacker News. The group is estimated to have targeted 24 organizations in the gambling, government, retail, and travel sectors across Australia, Brazil, China, India, Indonesia, the Philippines, South Korea, and Thailand. Six of these attacks were successful. The modus operandi of GambleForce is its exclusive reliance on open-source tools like dirsearch , sqlmap , tinyproxy , and redis-rogue-getshell at different stages of the attacks with the ultimate goal of exfiltrating ...

Cybersecurity researchers have unmasked a prolific threat actor known as farnetwork, who has been linked to five different ransomware-as-a-service (RaaS) programs over the past four years in various capacities. Singapore-headquartered Group-IB, which attempted to infiltrate a private RaaS program that uses the  Nokoyawa   ransomware  strain, said it underwent a "job interview" process with the threat actor, learning several valuable insights into their background and role within those RaaS programs. "Throughout the threat actor's cybercriminal career, which began in 2019, farnetwork has been involved in several connected ransomware projects, including JSWORM, Nefilim, Karma, and Nemty, as part of which they helped develop ransomware and manage the RaaS programs before launching their own RaaS program based on Nokoyawa ransomware," Nikolay Kichatov, threat intelligence analyst at Group-IB,  said . The latest disclosure comes nearly six months after the cyber...

Cybersecurity experts have shed light on a new cybercrime group known as  ShadowSyndicate  (formerly Infra Storm) that may have leveraged as many as seven different ransomware families over the past year. "ShadowSyndicate is a threat actor that works with various ransomware groups and affiliates of ransomware programs," Group-IB and Bridewell  said  in a joint technical report. The actor, active since July 16, 2022, has linked to ransomware activity related to Quantum, Nokoyawa, BlackCat, Royal, Cl0p, Cactus, and Play strains, while also deploying off-the-shelf post-exploitation tools like  Cobalt Strike  and  Sliver  as well as loaders such as  IcedID  and  Matanbuchus . The findings are based on a distinct SSH fingerprint (1ca4cbac895fc3bd12417b77fc6ed31d) discovered on 85 servers, 52 of which have been used as command-and-control (C2) for Cobalt Strike. Among those servers are eight different Cobalt Strike license keys (or wa...

A previously undocumented "phishing empire" has been linked to cyber attacks aimed at compromising Microsoft 365 business email accounts over the past six years. "The threat actor created a hidden underground market, named W3LL Store, that served a closed community of at least 500 threat actors who could purchase a custom phishing kit called W3LL Panel, designed to bypass MFA, as well as 16 other fully customized tools for business email compromise (BEC) attacks," Group-IB  said  in a report shared with The Hacker News. The phishing infrastructure is estimated to have targeted more than 56,000 corporate Microsoft 365 accounts and compromised at least 8,000 of them, primarily in the U.S., the U.K., Australia, Germany, Canada, France, the Netherlands, Switzerland, and Italy between October 2022 and July 2023, netting its operators $500,000 in illicit profits. Some of the prominent sectors infiltrated using the phishing solution include manufacturing, IT, consultin...

The Classiscam scam-as-a-service program has reaped the criminal actors $64.5 million in illicit earnings since its emergence in 2019. "Classiscam campaigns initially started out on classified sites, on which scammers placed fake advertisements and used social engineering techniques to convince users to pay for goods by transferring money to bank cards," Group-IB  said  in a new report. "Since then, Classiscam campaigns have become highly automated, and can be run on a host of other services, such as online marketplaces and carpooling sites." A majority of victims are based in Europe (62.2%), followed by the Middle East and Africa (18.2%), and the Asia-Pacific (13%). Germany, Poland, Spain, Italy, and Romania accounted for the highest number of fraudulent transactions registered in Classiscam chats.  First discovered in 2019, Classiscam is an  umbrella term  for an operation that encompasses 1,366 distinct groups on Telegram. The activities first targeted R...

A coordinated law enforcement operation across 25 African countries has led to the arrest of 14 suspected cybercriminals, INTERPOL  announced  Friday. The exercise, conducted in partnership with AFRIPOL, enabled investigators to identify 20,674 cyber networks that were linked to financial losses of more than $40 million. "The four-month Africa Cyber Surge II operation was launched in April 2023 and focused on identifying cybercriminals and compromised infrastructure," the agency said. As part of the operation, three suspects were arrested in Cameroon in connection with an online scam involving the fraudulent sale of works of art worth $850,000. Another suspect was arrested in Nigeria for defrauding a Gambian victim. Also arrested were two money mules linked to scams initiated through messaging platforms. The cyber networks comprised 3,786 command-and-control (C2) servers, 14,134 victim IP addresses tied to data stealer infections, 1,415 phishing links and domains, 939 ...

A city court in Moscow on Wednesday convicted Group-IB co-founder and CEO Ilya Sachkov of "high treason" and jailed him for 14 years in a "strict regime colony" over accusations of passing information to foreign spies. "The court found Sachkov guilty under Article 275 of the Russian Criminal Code (high treason) sentencing him to 14 years of incarceration in a maximum-security jail, restriction of freedom for one year and a fine of 500,000 rubles (about $5,550)," state news agency TASS  reported . Sachkov, who has been in custody  since September 2021  and denied wrongdoing, had been accused of handing over classified information to foreign intelligence in 2011, which the prosecutors said caused reputational damage to Russia's national interests. The exact nature of the charges is unclear. The 37-year-old is expected to appeal the decision, Bloomberg  said , adding, "Sachkov was alleged to have  given the U.S. government  information regardin...

A suspected senior member of a French-speaking hacking crew known as OPERA1ER has been arrested as part of an international law enforcement operation codenamed Nervone, Interpol has announced. "The group is believed to have stolen an estimated USD 11 million -- potentially as much as 30 million -- in more than 30 attacks across 15 countries in Africa, Asia, and Latin America," the agency  said . The arrest was made by authorities in Côte d'Ivoire early last month. Additional insight was provided by the U.S. Secret Service's Criminal Investigative Division and Booz Allen Hamilton DarkLabs. The financially motivated collective is also known by the aliases Common Raven, DESKTOP-GROUP, and NX$M$. Its modus operandi was  first exposed  by Group-IB and Orange CERT Coordination Center (Orange-CERT-CC) in November 2022, detailing its intrusions on banks, financial services, and telecom companies between March 2018 and October 2022. Earlier this January, Broadcom's S...

Cybersecurity researchers have exposed the workings of a scam ring called CryptosLabs that's estimated to have made €480 million in illegal profits by targeting users in French-speaking individuals in France, Belgium, and Luxembourg since April 2018. The syndicate's massive fake investment schemes primarily involve impersonating 40 well-known banks, fin-techs, asset management firms, and crypto platforms, setting up a scam infrastructure spanning over 350 domains hosted on more than 80 servers, Group-IB  said  in a deep-dive report. The Singapore-headquartered company described the criminal outfit as "operated by a hierarchy of kingpins, sales agents, developers, and call center operators" who are recruited to ensnare potential victims by promising high returns on their capital. "CryptoLabs made their scam schemes more convincing through region-focused tactics, such as hiring French-speaking callers as 'managers' and creating fake landing pages, socia...

Over 101,100 compromised OpenAI ChatGPT account credentials have found their way on illicit dark web marketplaces between June 2022 and May 2023, with India alone accounting for 12,632 stolen credentials. The credentials were discovered within information stealer logs made available for sale on the cybercrime underground, Group-IB said in a report shared with The Hacker News. "The number of available logs containing compromised ChatGPT accounts reached a peak of 26,802 in May 2023," the Singapore-headquartered company  said . "The Asia-Pacific region has experienced the highest concentration of ChatGPT credentials being offered for sale over the past year." Other countries with the most number of compromised ChatGPT credentials include Pakistan, Brazil, Vietnam, Egypt, the U.S., France, Morocco, Indonesia, and Bangladesh. A further analysis has revealed that the majority of logs containing ChatGPT accounts have been breached by the notorious Raccoon info steal...

A Chinese-speaking phishing gang dubbed  PostalFurious  has been linked to a new SMS campaign that's targeting users in the U.A.E. by masquerading as postal services and toll operators, per Group-IB. The fraudulent scheme entails sending users bogus text messages asking them to pay a vehicle trip fee to avoid additional fines. The messages also contain a shortened URL to conceal the actual phishing link. Clicking on the link directs the unsuspecting recipients to a fake landing page that's designed to capture payment credentials and personal data. The campaign is estimated to be active as of April 15, 2023. "The URLs from the texts lead to fake branded payment pages that ask for personal details, such as name, address, and credit card information," Group-IB  said . "The phishing pages appropriate the official name and logo of the impersonated postal service provider." The exact scale of the attacks is currently unknown. What's known is that the tex...

Cybersecurity researchers have unearthed previously undocumented attack infrastructure used by the prolific state-sponsored group  SideWinder  to strike entities located in Pakistan and China. This comprises a network of 55 domains and IP addresses used by the threat actor, cybersecurity companies Group-IB and Bridewell said in a joint report shared with The Hacker News. "The identified phishing domains mimic various organizations in the news, government, telecommunications, and financial sectors," researchers Nikita Rostovtsev, Joshua Penny, and Yashraj Solanki  said . SideWinder has been known to be active since at least 2012, with attack chains primarily leveraging spear-phishing as an intrusion mechanism to obtain a foothold into targeted environments. The target range of the group is widely believed to be associated with Indian espionage interests. The most frequently attacked nations include Pakistan, China, Sri Lanka, Afghanistan, Bangladesh, Myanmar, the Phil...

Ransomware affiliates associated with the Qilin ransomware-as-a-service (RaaS) scheme earn anywhere between 80% to 85% of each ransom payment, according to new findings from Group-IB. The cybersecurity firm said it was able to infiltrate the group in March 2023, uncovering details about the affiliates' payment structure and the inner workings of the RaaS program following a private conversation with a Qilin recruiter who goes by the online alias Haise. "Many Qilin ransomware attacks are customized for each victim to maximize their impact," the Singapore-headquartered company  said  in an exhaustive report. "To do this, the threat actors can leverage such tactics as changing the filename extensions of encrypted files and terminating specific processes and services." Qilin, also known as Agenda, was  first documented  by Trend Micro in August 2022, starting off as a Go-based ransomware before  switching to Rust  in December 2022. The adoption of Rust is...
