PureRAT Malware Spikes 4x in 2025, Deploying PureLogs to Target Russian Firms

May 21, 2025 Malware / Windows Security
Russian organizations have become the target of a phishing campaign that distributes malware called PureRAT, according to new findings from Kaspersky. "The campaign aimed at Russian business began back in March 2023, but in the first third of 2025 the number of attacks quadrupled compared to the same period in 2024," the cybersecurity vendor said . The attack chains, which have not been attributed to any specific threat actor, commence with a phishing email that contains a RAR file attachment or a link to the archive that masquerades as a Microsoft Word or a PDF document by making use of double extensions ("doc_054_[redacted].pdf.rar"). Present within the archive file is an executable that, when launched, copies itself to the "%AppData%" location of the compromised Windows machine under the name "task.exe" and creates a Visual Basic Script called "Task.vbs" in the Startup VBS folder. The executable then proceeds to unpack another ...

How to Detect Phishing Attacks Faster: Tycoon2FA Example

May 21, 2025 Malware Analysis / Threat Intelligence
It takes just one email to compromise an entire system. A single well-crafted message can bypass filters, trick employees, and give attackers the access they need. Left undetected, these threats can lead to credential theft, unauthorized access, and even full-scale breaches. As phishing techniques become more evasive, they can no longer be reliably caught by automated solutions alone. Let's take a closer look at how SOC teams can ensure fast, accurate detection of even the most evasive phishing attacks, using the example of Tycoon2FA, the number one phishing threat in the corporate environment today. Step 1: Upload a suspicious file or URL to the sandbox Let's consider a typical situation: a suspicious email gets flagged by your detection system, but it's unclear whether it's indeed malicious. The fastest way to check it is to run a quick analysis inside a malware sandbox. A sandbox is an isolated virtual machine where you can safely open files, click links, and observe behavior ...

Hazy Hawk Exploits DNS Records to Hijack CDC, Corporate Domains for Malware Delivery

Hazy Hawk Exploits DNS Records to Hijack CDC, Corporate Domains for Malware Delivery

May 20, 2025 Malware / Cloud Security
A threat actor known as Hazy Hawk has been observed hijacking abandoned cloud resources of high-profile organizations, including Amazon S3 buckets and Microsoft Azure endpoints, by leveraging misconfigurations in the Domain Name System (DNS) records. The hijacked domains are then used to host URLs that direct users to scams and malware via traffic distribution systems (TDSes), according to Infoblox. Some of the other resources usurped by the threat actor include those hosted on Akamai, Bunny CDN, Cloudflare CDN, GitHub, and Netlify. The DNS threat intelligence firm said it first discovered the threat actor after it gained control of several sub-domains associated with the U.S. Center for Disease Control (CDC) in February 2025. It has since been determined that other government agencies across the globe, prominent universities, and international corporations such as Deloitte, PricewaterhouseCoopers, and Ernst & Young have been victimized by the same threat actor since at least ...
100+ Fake Chrome Extensions Found Hijacking Sessions, Stealing Credentials, Injecting Ads

100+ Fake Chrome Extensions Found Hijacking Sessions, Stealing Credentials, Injecting Ads

May 20, 2025 Credential Theft / Browser Security
An unknown threat actor has been attributed to creating several malicious Chrome Browser extensions since February 2024 that masquerade as seemingly benign utilities but incorporate covert functionality to exfiltrate data, receive commands, and execute arbitrary code. "The actor creates websites that masquerade as legitimate services, productivity tools, ad and media creation or analysis assistants, VPN services, crypto, banking and more to direct users to install corresponding malicious extensions on Google's Chrome Web Store (CWS)," the DomainTools Intelligence (DTI) team said in a report shared with The Hacker News. While the browser add-ons appear to offer the advertised features, they also enable credential and cookie theft, session hijacking, ad injection, malicious redirects, traffic manipulation, and phishing via DOM manipulation. Another factor that works in the extensions' favor is that they are configured to grant themselves excessive permissions via...
South Asian Ministries Hit by SideWinder APT Using Old Office Flaws and Custom Malware

South Asian Ministries Hit by SideWinder APT Using Old Office Flaws and Custom Malware

May 20, 2025 Malware / Cyber Espionage
High-level government institutions in Sri Lanka, Bangladesh, and Pakistan have emerged as the target of a new campaign orchestrated by a threat actor known as SideWinder. "The attackers used spear phishing emails paired with geofenced payloads to ensure that only victims in specific countries received the malicious content," Acronis researchers Santiago Pontiroli, Jozsef Gegeny, and Prakas Thevendaran said in a report shared with The Hacker News. The attack chains leverage spear-phishing lures as a starting point to activate the infection process and deploy a known malware referred to as StealerBot. It's worth pointing out that the modus operandi is consistent with recent SideWinder attacks documented by Kaspersky in March 2025. Some of the targets of the campaign, per Acronis, include Bangladesh's Telecommunication Regulatory Commission, Ministry of Defence, and Ministry of Finance; Pakistan's Directorate of Indigenous Technical Development; and Sri Lanka...
Go-Based Malware Deploys XMRig Miner on Linux Hosts via Redis Configuration Abuse

Go-Based Malware Deploys XMRig Miner on Linux Hosts via Redis Configuration Abuse

May 20, 2025 Linux / Cryptojacking
Cybersecurity researchers are calling attention to a new Linux cryptojacking campaign that's targeting publicly accessible Redis servers. The malicious activity has been codenamed RedisRaider by Datadog Security Labs. "RedisRaider aggressively scans randomized portions of the IPv4 space and uses legitimate Redis configuration commands to execute malicious cron jobs on vulnerable systems," security researchers Matt Muir and Frederic Baguelin said . The end goal of the campaign is to drop a Go-based primary payload that's responsible for unleashing an XMRig miner on compromised systems. The activity entails using a bespoke scanner to identify publicly accessible Redis servers across the internet and then issuing an INFO command to determine if the instances are running on a Linux host. If it's found to be the case, the scanning algorithm proceeds to abuse Redis's SET command to inject a cron job. The malware then uses the CONFIG command to change the Redi...

New HTTPBot Botnet Launches 200+ Precision DDoS Attacks on Gaming and Tech Sectors

May 16, 2025 United States
Cybersecurity researchers are calling attention to a new botnet malware called HTTPBot that has been used to primarily single out the gaming industry, as well as technology companies and educational institutions in China. "Over the past few months, it has expanded aggressively, continuously leveraging infected devices to launch external attacks," NSFOCUS said in a report published this week. "By employing highly simulated HTTP Flood attacks and dynamic feature obfuscation techniques, it circumvents traditional rule-based detection mechanisms." HTTPBot, first spotted in the wild in August 2024, gets its name from the use of HTTP protocols to launch distributed denial-of-service attacks. Written in Golang, it's something of an anomaly given its targeting of Windows systems. The Windows-based botnet trojan is noteworthy for its use in precisely targeted attacks aimed at high-value business interfaces such as game login and payment systems. "This attack ...

New Chrome Vulnerability Enables Cross-Origin Data Leak via Loader Referrer Policy

May 15, 2025 Browser Security / Web Security
Google on Wednesday released updates to address four security issues in its Chrome web browser, including one for which it said there exists an exploit in the wild. The high-severity vulnerability, tracked as CVE-2025-4664 (CVSS score: 4.3), has been characterized as a case of insufficient policy enforcement in a component called Loader. "Insufficient policy enforcement in Loader in Google Chrome prior to 136.0.7103.113 allowed a remote attacker to leak cross-origin data via a crafted HTML page," according to a description of the flaw. The tech giant credited security researcher Vsevolod Kokorin (@slonser_) with detailing the flaw in X on May 5, 2025, adding it's aware "an exploit for CVE-2025-4664 exists in the wild." "Unlike other browsers, Chrome resolves the Link header on sub-resource requests," Kokorin said in a series of posts on X earlier this month. "The issue is that the Link header can set a referrer-policy. We can specify uns...
