Credential stuffing | Breaking Cybersecurity News | The Hacker News

The recently leaked trove of internal chat logs among members of the Black Basta ransomware operation has revealed possible connections between the e-crime gang and Russian authorities. The leak, containing over 200,000 messages from September 2023 to September 2024, was published by a Telegram user @ExploitWhispers last month. According to an analysis of the messages by cybersecurity company Trellix, Black Basta's alleged leader Oleg Nefedov (aka GG or AA) may have received help from Russian officials following his arrest in Yerevan, Armenia, in June 2024, allowing him to escape three days later. In the messages, GG claimed that he contacted high-ranking officials to pass through a "green corridor" and facilitate the extraction. "This knowledge from chat leaks makes it difficult for the Black Basta gang to completely abandon the way they operate and start a new RaaS from scratch without a reference to their previous activities," Trellix researchers Ja...

Credential stuffing attacks had a huge impact in 2024, fueled by a vicious circle of infostealer infections and data breaches . But things could be about to get worse still with Computer-Using Agents, a new kind of AI agent that enables low-cost, low-effort automation of common web tasks — including those frequently performed by attackers. Stolen credentials: The cyber criminal's weapon of choice in 2024 Stolen credentials were the #1 attacker action in 2023/24 , and the breach vector for 80% of web app attacks. Not surprising when you consider the fact that billions of leaked credentials are in circulation online, and attackers can pick up the latest drop for as little as $10 on criminal forums.  The criminal marketplace for stolen credentials is benefitting from the publicity of high-profile breaches in 2024 such as the attacks on Snowflake customers using credentials found in data breach dumps and compromised credential feeds from infostealer and mass phishing campaigns, r...

The latest Palo Alto Networks Unit 42 Cloud Threat Report found that sensitive data is found in 66% of cloud storage buckets. This data is vulnerable to ransomware attacks. The SANS Institute recently reported that these attacks can be performed by abusing the cloud provider's storage security controls and default settings. "In just the past few months, I have witnessed two different methods for executing a ransomware attack using nothing but legitimate cloud security features," warns Brandon Evans, security consultant and SANS Certified Instructor. Halcyon disclosed an attack campaign that leveraged one of Amazon S3's native encryption mechanisms, SSE-C, to encrypt each of the target buckets. A few months prior, security consultant Chris Farris demonstrated how attackers could perform a similar attack using a different AWS security feature, KMS keys with external key material, using simple scripts generated by ChatGPT. "Clearly, this topic is top-of-mind for both threat actors and ...

Last week, the notorious hacker gang, ShinyHunters, sent shockwaves across the globe by allegedly plundering 1.3 terabytes of data from 560 million users. This colossal breach, with a price tag of $500,000, could expose the personal information of a massive swath of a live event company's clientele, igniting a firestorm of concern and outrage.  Let's review the facts: two large organizations announced that they suffered a data breach, identifying unauthorized activity within a third-party cloud database environment. The accessed business records contained critical information on some employees, a large number of customers and other key business data.  The cloud connection  What might link these two breaches is the cloud data company Snowflake, which counts among its users both organizations. Snowflake did publish a warning with CISA , indicating a "recent increase in cyber threat activity targeting customer accounts on its cloud data platform." Snowflake issued a reco...

Okta is warning that a cross-origin authentication feature in Customer Identity Cloud (CIC) is susceptible to credential stuffing attacks orchestrated by threat actors. "We observed that the endpoints used to support the cross-origin authentication feature being attacked via credential stuffing for a number of our customers," the Identity and access management (IAM) services provider said . The suspicious activity commenced on April 15, 2024, with the company noting that it "proactively" informed customers that had the feature enabled. It did not disclose how many customers were impacted by the attacks. Credential stuffing is a type of cyber attack in which adversaries attempt to sign in to online services using an already available list of usernames and passwords obtained either from previous data breaches, or from phishing and malware campaigns. As recommended actions, users are being asked to review tenant logs for any signs of unexpected login events – ...

Identity and access management (IAM) services provider Okta has warned of a spike in the "frequency and scale" of credential stuffing attacks aimed at online services. These unprecedented attacks, observed over the last month, are said to be facilitated by "the broad availability of residential proxy services, lists of previously stolen credentials ('combo lists'), and scripting tools," the company  said  in an alert published Saturday. The findings build on a  recent advisory  from Cisco, which cautioned of a global surge in brute-force attacks targeting various devices, including Virtual Private Network (VPN) services, web application authentication interfaces, and SSH services, since at least March 18, 2024. "These attacks all appear to be originating from TOR exit nodes and a range of other anonymizing tunnels and proxies," Talos noted at the time, adding targets of the attacks comprise VPN appliances from Cisco, Check Point, Fortinet, Soni...

At a little overt halfway through 2023, credential theft is still a major thorn in the side of IT teams. The heart of the problem is the value of data to cybercriminals and the evolution of the techniques they use to get hold of it. The  2023 Verizon Data Breach Investigations Report (DBIR)  revealed that 83% of breaches involved external actors, with almost all attacks being financially motivated. Of these breaches by external actors, 49% involved the use of stolen credentials.  We'll explore why credential theft is still such an attractive (and successful) attack route, and look at how IT security teams can fight back in the second half of 2023 and beyond. Users are still often the weak link The hallmarks of many successful cyberattacks are the determination, inventiveness, and patience threat actors show. Though a user may spot some attacks through security and awareness training, it only takes one well-crafted attack to catch them. Sometimes all it takes is for a ...

The case for browser fingerprinting: personalizing user experience, improving fraud detection, and optimizing login security Have you ever heard of browser fingerprinting? You should! It's an online user identification technique that collects information about a visitor's web browser and its configuration preferences to associate individual browsing sessions with a single website visitor.  With browser fingerprinting, many pieces of data can be collected about a user's web browser and device, such as screen resolution, location, language, and operating system. When you stitch these pieces together, they reveal a unique combination of information that forms every user's visitor ID or "digital fingerprint." Websites can use the visitor ID in various ways, including personalizing the user's experience, improving fraud detection, and optimizing login security. This article discusses the case for browser fingerprinting and how to use it safely on your websi...
