Cybersecurity researchers have taken the wraps off a previously undocumented ransomware strain called  Rorschach  that's both sophisticated and fast. "What makes Rorschach stand out from other ransomware strains is its high level of customization and its technically unique features that have not been seen before in ransomware," Check Point Research  said  in a new report. "In fact, Rorschach is one of the  fastest ransomware strains  ever observed, in terms of the speed of its encryption." The cybersecurity firm said it observed the ransomware deployed against an unnamed U.S.-based company, adding it found no branding or overlaps that connect it to any previously known ransomware actors. However, further analysis of Rorschach's source code reveals similarities to  Babuk ransomware , which suffered a leak in September 2021, and  LockBit 2.0 . On top of that, the ransom notes sent out to the victims appear to be inspired by that of  Yanluow...

Chromium-based web browsers are the target of a new malware called Rilide that masquerades itself as a seemingly legitimate extension to harvest sensitive data and siphon cryptocurrency. "Rilide malware is disguised as a legitimate Google Drive extension and enables threat actors to carry out a broad spectrum of malicious activities, including monitoring browsing history, taking screenshots, and injecting malicious scripts to withdraw funds from various cryptocurrency exchanges," Trustwave SpiderLabs Research said in a report shared with The Hacker News. What's more, the stealer malware can display forged dialogs to deceive users into entering a two-factor authentication code to withdraw digital assets. Trustwave said it identified two different campaigns involving  Ekipa RAT  and  Aurora Stealer  that led to the installation of the malicious browser extension. While Ekipa RAT is distributed via booby-trapped Microsoft Publisher files, rogue Google Ads act a...

The threat actor known as  Arid Viper  has been observed using refreshed variants of its malware toolkit in its attacks targeting Palestinian entities since September 2022. Symantec, which is tracking the group under its insect-themed moniker Mantis,  said  the adversary is "going to great lengths to maintain a persistent presence on targeted networks." Also known by the names  APT-C-23 and Desert Falcon , the hacking group has been linked to attacks aimed at Palestine and the Middle East at least since 2014. Mantis has used an arsenal of homemade malware tools such as  ViperRat ,  FrozenCell  (aka VolatileVenom), and  Micropsia  to execute and conceal its campaigns across Windows, Android, and iOS platforms. The threat actors are believed to be native Arabic speakers and based in Palestine, Egypt, and Turkey, according to a  report  published by Kaspersky in February 2015. Prior public reporting has also  tied the g...

Collaboration sits at the essence of SaaS applications. The word, or some form of it, appears in the top two headlines on Google Workspace's homepage. It can be found six times on Microsoft 365's homepage, three times on Box, and once on Workday. Visit nearly any SaaS site, and odds are 'collaboration' will appear as part of the app's key selling point.  By sitting on the cloud, content within the applications is immediately shareable, making it easier than ever to work with others.  However, that shareability is a two-sided coin. On the flip side are often sensitive links sitting on public-facing websites that can be easily accessed. The exposure caused by leaked documents can cause tremendous harm, from competitors trying to gather corporate secrets to whistleblowers sharing internal information with reporters or legislators. As integral as collaboration is to SaaS, sharing links creates a high-risk situation, and real-life breaches, that can be mitigated through the righ...

Microsoft has announced plans to automatically block embedded files with "dangerous extensions" in OneNote following reports that the note-taking service is being  increasingly abused  for malware delivery. Up until now, users were shown a dialog warning them that opening such attachments could harm their computer and data, but it was possible to dismiss the prompt and open the files. That's going to change going forward. Microsoft said it intends to prevent users from directly opening an embedded file with a dangerous extension and display the message: "Your administrator has blocked your ability to open this file type in OneNote." The update is expected to start rolling out with Version 2304 later this month and only impacts OneNote for Microsoft 365 on devices running Windows. It does not affect other platforms, including macOS, Android, and iOS, as well as OneNote versions available on the web and for Windows 10. "By default, OneNote blocks the sa...

The adversary behind the  supply chain attack targeting 3CX  deployed a second-stage implant specifically singling out a small number of cryptocurrency companies. Russian cybersecurity firm Kaspersky, which has been  internally tracking  the versatile backdoor under the name  Gopuram  since 2020, said it observed an increase in the number of infections in March 2023 coinciding with the 3CX breach. Gopuram's primary function is to connect to a command-and-control (C2) server and await further instructions that allow the attackers to interact with the victim's file system, create processes, and launch as many as eight in-memory modules. The backdoor's links to North Korea stem from the fact that it "co-existed on victim machines with  AppleJeus , a backdoor attributed to the Korean-speaking threat actor Lazarus," detailing an attack on an unnamed crypto firm located in Southeast Asia in 2020. The targeting of cryptocurrency companies is another tell...

Data storage devices maker Western Digital on Monday disclosed a "network security incident" that involved unauthorized access to its systems. The  breach  is said to have occurred on March 26, 2023, enabling an unnamed third party to gain access to a "number of the company's systems." Following the discovery of the hack, Western Digital said it has initiated incident response efforts and enlisted the help of cybersecurity and forensic experts to conduct an investigation. It also said it's coordinating with law enforcement agencies on the matter, adding the probe is in its initial stages. The company has taken several of its services offline, noting that the threat actor may have obtained "certain data from its systems" and that it's working on estimating the nature and scope of the data accessed. While Western Digital did not reveal the exact services that are impacted, the  My Cloud status page  shows that cloud, proxy, web, authentica...

The Italian data protection watchdog, Garante per la Protezione dei Dati Personali (aka Garante), has imposed a temporary ban of OpenAI's ChatGPT service in the country, citing data protection concerns. To that end, it has ordered the company to stop processing users' data with immediate effect, stating it intends to investigate the company over whether it's unlawfully processing such data in violation of the E.U. General Data Protection Regulation ( GDPR ) laws. "No information is provided to users and data subjects whose data are collected by Open AI," the Garante  noted . "More importantly, there appears to be no legal basis underpinning the massive collection and processing of personal data in order to 'train' the algorithms on which the platform relies." ChatGPT, which is estimated to have reached over 100 million monthly active users since its release late last year,  has not   disclosed   what it used  to train its latest large languag...

Privileged Access Management (PAM) solutions are regarded as the common practice to prevent identity threats to administrative accounts. In theory, the PAM concept makes absolute sense: place admin credentials in a vault, rotate their passwords, and closely monitor their sessions. However, the harsh reality is that the vast majority of PAM projects either become a years-long project, or even come to a halt altogether, preventing them from delivering their promised security value. In this article, we explore what makes  service accounts a key obstacle in PAM onboarding . We'll learn why vaulting and password rotation of service accounts are an almost impossible task, resulting in leaving them exposed to compromise. We'll then conclude with introducing how Silverfort enables identity teams, for the first time, to overcome these challenges with automated discovery, monitoring, and protection of service accounts, and streamline PAM onboarding process in mere weeks. The PAM Promi...
