A large-scale malware campaign has been found leveraging a vulnerable Windows driver associated with Adlice's product suite to sidestep detection efforts and deliver the Gh0st RAT malware . "To further evade detection, the attackers deliberately generated multiple variants (with different hashes) of the 2.0.2 driver by modifying specific PE parts while keeping the signature valid," Check Point said in a new report published Monday. The cybersecurity company said the malicious activity involved thousands of first-stage malicious samples that are used to deploy a program capable of terminating endpoint detection and response (EDR) software by means of what's called a bring your own vulnerable driver ( BYOVD ) attack. As many as 2,500 distinct variants of the legacy version 2.0.2 of the vulnerable RogueKiller Antirootkit Driver, truesight.sys, have been identified on the VirusTotal platform, although the number is believed to be likely higher. The EDR-killer module...

The threat actors behind the RansomHub ransomware-as-a-service (RaaS) scheme have been observed leveraging now-patched security flaws in Microsoft Active Directory and the Netlogon protocol to escalate privileges and gain unauthorized access to a victim network's domain controller as part of their post-compromise strategy. "RansomHub has targeted over 600 organizations globally, spanning sectors such as healthcare, finance, government, and critical infrastructure, firmly establishing it as the most active ransomware group in 2024," Group-IB analysts said in an exhaustive report published this week. The ransomware group first emerged in February 2024, acquiring the source code associated with the now-defunct Knight (formerly Cyclops) RaaS gang from the RAMP cybercrime forum to speed up its operations. About five months later, an updated version of the locker was advertised on the illicit marketplace with capabilities to remotely encrypt data via SFTP protocol. It co...

A widespread phishing campaign has been observed leveraging bogus PDF documents hosted on the Webflow content delivery network (CDN) with an aim to steal credit card information and commit financial fraud. "The attacker targets victims searching for documents on search engines, resulting in access to malicious PDF that contains a CAPTCHA image embedded with a phishing link, leading them to provide sensitive information," Netskope Threat Labs researcher Jan Michael Alcantara said . The activity, ongoing since the second half of 2024, entails users looking for book titles, documents, and charts on search engines like Google to redirect users to PDF files hosted on Webflow CDN. These PDF files come embedded with an image that mimics a CAPTCHA challenge, causing users who click on it to be taken to a phishing page that, this time, hosts a real Cloudflare Turnstile CAPTCHA. In doing so, the attackers aim to lend the process a veneer of legitimacy, fooling victims into think...

Apple on Monday released out-of-band security updates to address a security flaw in iOS and iPadOS that it said has been exploited in the wild. Assigned the CVE identifier CVE-2025-24200 (CVSS score: 4.6), the vulnerability has been described as an authorization issue that could make it possible for a malicious actor to disable USB Restricted Mode on a locked device as part of a cyber physical attack. This suggests that the attackers require physical access to the device in order to exploit the flaw. Introduced in iOS 11.4.1, USB Restricted Mode prevents an Apple iOS and iPadOS device from communicating with a connected accessory if it has not been unlocked and connected to an accessory within the past hour. The feature is seen as an attempt to prevent digital forensics tools like Cellebrite or GrayKey , which are mainly used by law enforcement agencies, from gaining unauthorized entry to a confiscated device and extracting sensitive data. In line with advisories of this k...

In cybersecurity, the smallest crack can lead to the biggest breaches. A leaked encryption key, an unpatched software bug, or an abandoned cloud storage bucket—each one seems minor until it becomes the entry point for an attack. This week, we've seen cybercriminals turn overlooked weaknesses into major security threats, proving once again that no system is too small to be targeted. The question isn't whether attackers will find a way in—it's whether you'll be prepared when they do. Let's break down what you need to know. ⚡ Threat of the Week Microsoft Warns of Attacks Exploiting ASP.NET Machine Keys — Threat actors are exploiting publicly disclosed ASP.NET machine keys to inject and execute malicious code responsible for launching the Godzilla post-exploitation framework. Microsoft said it has identified over 3,000 publicly disclosed keys that could be used for these types of attacks dubbed ViewState code injection. The company also said it removed key-related artifacts from ...

A new audit of DeepSeek's mobile app for the Apple iOS operating system has found glaring security issues, the foremost being that it sends sensitive data over the internet sans any encryption, exposing it to interception and manipulation attacks. The assessment comes from NowSecure, which also found that the app fails to adhere to best security practices and that it collects extensive user and device data. "The DeepSeek iOS app sends some mobile app registration and device data over the Internet without encryption," the company said . "This exposes any data in the internet traffic to both passive and active attacks." The teardown also revealed several implementation weaknesses when it comes to applying encryption on user data. This includes the use of an insecure symmetric encryption algorithm ( 3DES ), a hard-coded encryption key, and the reuse of initialization vectors . What's more, the data is sent to servers that are managed by a cloud compute a...

The advanced persistent threat (APT) group known as UAC-0063 has been observed leveraging legitimate documents obtained by infiltrating one victim to attack another target with the goal of delivering a known malware dubbed HATVIBE. "This research focuses on completing the picture of UAC-0063's operations, particularly documenting their expansion beyond their initial focus on Central Asia, targeting entities such as embassies in multiple European countries, including Germany, the U.K., the Netherlands, Romania, and Georgia," Martin Zugec, technical solutions director at Bitdefender, said in a report shared with The Hacker News. UAC-0063 was first flagged by the Romanian cybersecurity company in May 2023 in connection with a campaign that targeted government entities in Central Asia with a data exfiltration malware known as DownEx (aka STILLARCH). It's suspected to share links with a known Russian state-sponsored actor called APT28. Merely weeks later, the Compu...

Ilya Lichtenstein, who pleaded guilty to the 2016 hack of cryptocurrency stock exchange Bitfinex, has been sentenced to five years in prison, the U.S. Department of Justice (DoJ) announced Thursday. Lichtenstein was charged for his involvement in a money laundering scheme that led to the theft of nearly 120,000 bitcoins (valued at over $10.5 billion at current prices) from the crypto exchange. Heather Rhiannon Morgan, his wife, also pleaded guilty to the same crimes last year. They were both arrested in February 2022. Morgan is scheduled to be sentenced on November 18. "Lichtenstein, 35, hacked into Bitfinex's network in 2016, using advanced hacking tools and techniques," the DoJ said in a press statement.

TRM Labs said Lichtenstein exploited a vulnerability in Bit...

Canadian law enforcement authorities have arrested an individual who is suspected to have conducted a series of hacks stemming from the breach of cloud data warehousing platform Snowflake earlier this year. The individual in question, Alexander "Connor" Moucka (aka Judische and Waifu), was apprehended on October 30, 2024, on the basis of a provisional arrest warrant, following a request by the U.S. The development was first reported by Bloomberg and corroborated by 404 Media . The exact nature of the charges against Moucka is currently not known. In June 2024, Snowflake disclosed that a "limited number" of its customers were targeted as part of a targeted campaign. Later, Google-owned Mandiant attributed it to a financially motivated threat group called UNC5537. "UNC5537 comprises members based in North America, and collaborates with an additional member in Turkey," the company assessed with moderate confidence at the time, adding approximately 16...

Cybersecurity researchers have discovered an advanced version of the Qilin ransomware sporting increased sophistication and tactics to evade detection. The new variant is being tracked by cybersecurity firm Halcyon under the moniker Qilin.B. "Notably, Qilin.B now supports AES-256-CTR encryption for systems with AESNI capabilities, while still retaining Chacha20 for systems that lack this support," the Halcyon Research Team said in a report shared with The Hacker News. "Additionally, RSA-4096 with OAEP padding is used to safeguard encryption keys, making file decryption without the attacker's private key or captured seed values impossible." Qilin, also known as Agenda , first came to the attention of the cybersecurity community in July/August 2022, with initial versions written in Golang before switching to Rust. A May 2023 report from Group-IB revealed that the ransomware-as-a-service (RaaS) scheme allows its affiliates to anywhere between 80% to 85% of ...
