USB drive attacks constitute a significant cybersecurity risk, taking advantage of the everyday use of USB devices to deliver malware and circumvent traditional network security measures. These attacks lead to data breaches, financial losses, and operational disruptions, with lasting impacts on an organization's reputation. An example is the Stuxnet worm discovered in 2010, a malware designed to target industrial control systems, specifically Iran's nuclear enrichment facilities. It exploited multiple zero-day vulnerabilities and spread primarily through USB drives, making it one of the first examples of a cyberattack with real-world physical effects. Stuxnet exposed the risks of removable media and raised global awareness of cybersecurity threats to critical infrastructure. How USB drive attacks propagate Attackers use various methods to deliver malicious payloads via USB drives, targeting individuals and organizations.  Drop attacks : Infected USB drives are deliberatel...

The threat actor known as Dark Caracal has been attributed to a campaign that deployed a remote access trojan called Poco RAT in attacks targeting Spanish-speaking targets in Latin America in 2024. The findings come from Russian cybersecurity company Positive Technologies, which described the malware as loaded with a "full suite of espionage features." "It could upload files, capture screenshots, execute commands, and manipulate system processes," researchers Denis Kazakov and Sergey Samokhin said in a technical report published last week. Poco RAT was previously documented by Cofense in July 2024, detailing the phishing attacks aimed at mining, manufacturing, hospitality, and utilities sectors. The infection chains are characterized by the use of finance-themed lures that trigger a multi-step process to deploy the malware. While the campaign was not attributed to any threat at that time, Positive Technologies said it identified tradecraft overlaps with Dar...

The rapid adoption of cloud services, SaaS applications, and the shift to remote work have fundamentally reshaped how enterprises operate. These technological advances have created a world of opportunity but also brought about complexities that pose significant security threats. At the core of these vulnerabilities lies Identity —the gateway to enterprise security and the number one attack vector for bad actors. Explore the importance of modernizing Identity strategies and the benefits of centralizing Identity within your security ecosystem to safeguard your organization from costly breaches while enhancing operational efficiency. The rise of fragmented tech stacks Gone are the days when enterprises relied on a single solution tied to a comprehensive license agreement. Businesses today prioritize agility and performance, opting for “best-in-breed” solutions that patch together fragmented tech ecosystems. While these advanced tech stacks provide flexibility, they also create signif...

Threat actors deploying the Black Basta and CACTUS ransomware families have been found to rely on the same BackConnect (BC) module for maintaining persistent control over infected hosts, a sign that affiliates previously associated with Black Basta may have transitioned to CACTUS. "Once infiltrated, it grants attackers a wide range of remote control capabilities, allowing them to execute commands on the infected machine," Trend Micro said in a Monday analysis. "This enables them to steal sensitive data, such as login credentials, financial information, and personal files." It's worth noting that details of the BC module, which the cybersecurity company is tracking as QBACKCONNECT owing to overlaps with the QakBot loader, was first documented in late January 2025 by both Walmart's Cyber Intelligence team and Sophos, the latter of which has designated the cluster the name STAC5777.  Over the past year, Black Basta attack chains have increasingly leve...

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...

Internet service providers (ISPs) in China and the West Coast of the United States have become the target of a mass exploitation campaign that deploys information stealers and cryptocurrency miners on compromised hosts. The findings come from the Splunk Threat Research Team, which said the activity also led to the delivery of various binaries that facilitate data exfiltration as well as offer ways to establish persistence on the systems. The unidentified threat actors performed "minimal intrusive operations to avoid detection, with the exception of artifacts created by accounts already compromised," the Cisco-owned company said in a technical report published last week. "This actor also moves and pivots primarily by using tools that depend and run on scripting languages (e.g., Python and Powershell), allowing the actor to perform under restricted environments and use API calls (e.g., Telegram) for C2 [command-and-control] operations." The attacks have been ob...

Threat actors are targeting Amazon Web Services ( AWS ) environments to push out phishing campaigns to unsuspecting targets, according to findings from Palo Alto Networks Unit 42. The cybersecurity company is tracking the activity cluster under the name TGR-UNK-0011 (short for a threat group with unknown motivation ), which it said overlaps with a group known as JavaGhost. TGR-UNK-0011 is known to be active since 2019. "The group focused historically on defacing websites," security researcher Margaret Kelley said . "In 2022, they pivoted to sending out phishing emails for financial gain." It's worth noting that these attacks do not exploit any vulnerability in AWS. Rather, the threat actors take advantage of misconfigurations in victims' environments that expose their AWS access keys in order to send phishing messages by abusing Amazon Simple Email Service (SES) and WorkMail services. In doing so, the modus operandi offers the benefit of not having to...

In 2024, global ransomware attacks hit 5,414, an 11% increase from 2023.  After a slow start, attacks spiked in Q2 and surged in Q4, with 1,827 incidents (33% of the year's total). Law enforcement actions against major groups like LockBit caused fragmentation, leading to more competition and a rise in smaller gangs. The number of active ransomware groups jumped 40%, from 68 in 2023 to 95 in 2024. New Ransomware Groups to Watch In 2023 there were just 27 new groups. 2024 saw a dramatic rise with 46 new groups detected. As the year went on the number of groups accelerated with Q4 2024 having 48 groups active.  Of the 46 new ransomware groups in 2024, RansomHub became dominant, exceeding LockBit's activity. At Cyberint, now a Check Point Company, the research team is constantly researching the latest ransomware groups and analyzing them for potential impact. This blog will look at 3 new players, the aforementioned RansomHub, Fog and Lynx and examine their impact in 202...

A dataset used to train large language models (LLMs) has been found to contain nearly 12,000 live secrets, which allow for successful authentication. The findings once again highlight how hard-coded credentials pose a severe security risk to users and organizations alike, not to mention compounding the problem when LLMs end up suggesting insecure coding practices to their users. Truffle Security said it downloaded a December 2024 archive from Common Crawl , which maintains a free, open repository of web crawl data. The massive dataset contains over 250 billion pages spanning 18 years.  The archive specifically contains 400TB of compressed web data, 90,000 WARC files (Web ARChive format), and data from 47.5 million hosts across 38.3 million registered domains. The company's analysis found that there are 219 different secret types in the Common Crawl archive, including Amazon Web Services (AWS) root keys, Slack webhooks, and Mailchimp API keys.
