A zero-day security flaw in Telegram's mobile app for Android called EvilVideo made it possible for attackers to malicious files disguised as harmless-looking videos. The exploit appeared for sale for an unknown price in an underground forum on June 6, 2024, ESET said. Following responsible disclosure on June 26, the issue was addressed by Telegram in version 10.14.5 released on July 11. "Attackers could share malicious Android payloads via Telegram channels, groups, and chat, and make them appear as multimedia files," security researcher Lukáš Štefanko said in a report. It's believed that the payload is concocted using Telegram's application programming interface ( API ), which allows for programmatic uploads of multimedia files to chats and channels. In doing so, it enables an attacker to camouflage a malicious APK file as a 30-second video.  Users who click on the video are displayed an actual warning message stating the video cannot be played and urges t

The online criminal bazaar BreachForums has been resurrected merely two weeks after a U.S.-led coordinated law enforcement action dismantled and seized control of its infrastructure. Cybersecurity researchers and dark web trackers Brett Callow , Dark Web Informer , and FalconFeeds revealed the site's online return at breachforums[.]st – one of the dismantled sites – by a user named ShinyHunters, who has since offered for sale a 1.3 TB database containing details of allegedly 560 million Ticketmaster customers for $500,000. This includes full names, addresses, email addresses, phone numbers, ticket sales and event information, and the last four digits of credit cards and their associated expiration dates. However, in an interesting twist, visitors of the site are now being asked to sign up for an account in order to view the content. The development follows a joint law enforcement action that seized all the new domains belonging to BreachForums (breachforums[.]st/.cx/.is/.

As a vCISO, you are responsible for your client's cybersecurity strategy and risk governance. This incorporates multiple disciplines, from research to execution to reporting. Recently, we published a comprehensive playbook for vCISOs, "Your First 100 Days as a vCISO – 5 Steps to Success" , which covers all the phases entailed in launching a successful vCISO engagement, along with recommended actions to take, and step-by-step examples.  Following the success of the playbook and the requests that have come in from the MSP/MSSP community, we decided to drill down into specific parts of vCISO reporting and provide more color and examples. In this article, we focus on how to create compelling narratives within a report, which has a significant impact on the overall MSP/MSSP value proposition.  This article brings the highlights of a recent guided workshop we held, covering what makes a successful report and how it can be used to enhance engagement with your cyber security clients.

The Pakistan-nexus  Transparent Tribe  actor has been linked to a new set of attacks targeting Indian government, defense, and aerospace sectors using cross-platform malware written in Python, Golang, and Rust. "This cluster of activity spanned from late 2023 to April 2024 and is anticipated to persist," the BlackBerry Research and Intelligence Team  said  in a technical report published early last week. The spear-phishing campaign is also notable for its abuse of popular online services such as Discord, Google Drive, Slack, and Telegram, once again underscoring how threat actors are  adopting legitimate programs  into their attack flows. According to BlackBerry, the targets of the email-based attacks included three companies that are crucial stakeholders and clients of the Department of Defense Production ( DDP ). All the three companies targeted are headquartered in the Indian city of Bengaluru. While the names of the firms were not disclosed, indications are that the

Government entities in the Middle East have been targeted as part of a previously undocumented campaign to deliver a new backdoor dubbed CR4T. Russian cybersecurity company Kaspersky said it discovered the activity in February 2024, with evidence suggesting that it may have been active since at least a year prior. The campaign has been codenamed  DuneQuixote . "The group behind the campaign took steps to prevent collection and analysis of its implants and implemented practical and well-designed evasion methods both in network communications and in the malware code," Kaspersky  said . The starting point of the attack is a dropper, which comes in two variants -- a regular dropper that's either implemented as an executable or a DLL file and a tampered installer file for a legitimate tool named  Total Commander . Regardless of the method used, the primary function of the dropper is to extract an embedded command-and-control (C2) address that's decrypted using a nove

A suspected Vietnamese-origin threat actor has been observed targeting victims in several Asian and Southeast Asian countries with malware designed to harvest valuable data since at least May 2023. Cisco Talos is tracking the cluster under the name  CoralRaider , describing it as financially motivated. Targets of the campaign include India, China, South Korea, Bangladesh, Pakistan, Indonesia, and Vietnam. "This group focuses on stealing victims' credentials, financial data, and social media accounts, including business and advertisement accounts," security researchers Chetan Raghuprasad and Joey Chen  said . "They use RotBot, a customized variant of Quasar RAT, and XClient stealer as payloads." Other commodity malware used by the group comprises a combination of remote access trojans and information stealers such as  AsyncRAT ,  NetSupport RAT , and Rhadamanthys . The targeting of business and advertisement accounts has been of particular focus for attacke

In June 2017, a  study  of more than 3,000 Massachusetts Institute of Technology (MIT) students  published  by the National Bureau for Economic Research (NBER) found that 98% of them were willing to give away their friends' email addresses in exchange for free pizza. "Whereas people say they care about privacy, they are willing to relinquish private data quite easily when incentivized to do so," the research said, pointing out a what's called the privacy paradox. Now, nearly seven years later, Telegram has introduced a new feature that gives some users a free  premium membership  in exchange for allowing the popular messaging app to use their phone numbers as a relay for sending one-time passwords (OTPs) to other users who are attempting to sign in to the platform. The feature, called Peer-to-Peer Login (P2PL), is currently being tested in selected countries for Android users of Telegram. It was first spotted by  tginfo  in February 2024 (via  @AssembleDebug ). A

In the past 2 years, we have observed a significant surge in hacktivism activity due to ongoing wars and geopolitical conflicts in various regions. Since the war against Ukraine began, we have witnessed a notable mobilization of non-state and state-backed actors alike, forming new groups or joining existing hacker collectives.  We understand hacktivism as a form of computer hacking that is done to further the goals of political or social  activism 1 . While  activism  describes a normal, non-disruptive use of the Internet in order to support a specific cause (online petitions, fundraising, coordinating activities),  hacktivism  includes operations that use hacking techniques with the intent to disrupt but not to cause serious harm (e.g., data theft, website defacements, redirects, Denial-of-Service attacks). Cyber operations that inherit a willingness or intent to cause harm to physical property, severe economic damage or loss of life would be referred to as  cyberterrorism, 2, 3  Th

Threat actors are leveraging bogus Facebook job advertisements as a lure to trick prospective targets into installing a new Windows-based stealer malware codenamed  Ov3r_Stealer . "This malware is designed to steal credentials and crypto wallets and send those to a Telegram channel that the threat actor monitors," Trustwave SpiderLabs said in a report shared with The Hacker News. Ov3r_Stealer is capable of siphoning IP address-based location, hardware info, passwords, cookies, credit card information, auto-fills, browser extensions, crypto wallets, Microsoft Office documents, and a list of antivirus products installed on the compromised host. While the exact end goal of the campaign is unknown, it's likely that the stolen information is offered for sale to other threat actors. Another possibility is that Ov3r_Stealer could be updated over time to act as a  QakBot-like loader  for additional payloads, including ransomware. The starting point of the attack is a weapo

Employment agencies and retail companies chiefly located in the Asia-Pacific (APAC) region have been targeted by a previously undocumented threat actor known as  ResumeLooters  since early 2023 with the goal of stealing sensitive data. Singapore-headquartered Group-IB said the hacking crew's activities are geared towards job search platforms and the theft of resumes, with as many as 65 websites compromised between November 2023 and December 2023. The stolen files are estimated to contain 2,188,444 user data records, of which 510,259 have been taken from job search websites. Over two million unique email addresses are present within the dataset. "By using SQL injection attacks against websites, the threat actor attempts to steal user databases that may include names, phone numbers, emails, and DoBs, as well as information about job seekers' experience, employment history, and other sensitive personal data," security researcher Nikita Rostovcev  said  in a report sh

Cybersecurity researchers are calling attention to the "democratization" of the phishing ecosystem owing to the emergence of Telegram as an epicenter for cybercrime, enabling threat actors to mount a mass attack for as little as $230. "This messaging app has transformed into a bustling hub where seasoned cybercriminals and newcomers alike exchange illicit tools and insights creating a dark and well-oiled supply chain of tools and victims' data," Guardio Labs researchers Oleg Zaytsev and Nati Tal  said  in a new report. "Free samples, tutorials, kits, even hackers-for-hire – everything needed to construct a complete end-to-end malicious campaign." The company also described Telegram as a "scammers paradise" and a "breeding ground for modern phishing operations." This is not the first time the popular messaging platform has  come under the radar  for facilitating malicious activities, which are in part driven by its lenient modera

Threat actors have been observed leveraging a now-patched security flaw in Microsoft Windows to deploy an open-source information stealer called  Phemedrone Stealer . "Phemedrone targets web browsers and data from cryptocurrency wallets and messaging apps such as Telegram, Steam, and Discord," Trend Micro researchers Peter Girnus, Aliakbar Zahravi, and Simon Zuckerbraun  said . "It also takes screenshots and gathers system information regarding hardware, location, and operating system details. The stolen data is then sent to the attackers via Telegram or their command-and-control (C&C) server." The attacks leverage  CVE-2023-36025  (CVSS score: 8.8), a security bypass vulnerability in Windows SmartScreen, that could be exploited by tricking a user into clicking on a specially crafted Internet Shortcut (.URL) or a hyperlink pointing to an Internet Shortcut file. The actively-exploited shortcoming was  addressed  by Microsoft as part of its November 2023 Patch Tuesday updates.

Threat actors operating under the name Anonymous Arabic have released a remote access trojan (RAT) called  Silver RAT  that's equipped to bypass security software and stealthily launch hidden applications. "The developers operate on multiple hacker forums and social media platforms, showcasing an active and sophisticated presence," cybersecurity firm Cyfirma  said  in a report published last week. The actors, assessed to be of Syrian origin and linked to the development of another RAT known as S500 RAT, also run a Telegram channel offering various services such as the distribution of cracked RATs, leaked databases, carding activities, and the sale of Facebook and X (formerly Twitter) bots. The social media bots are then utilized by other cyber criminals to promote various illicit services by automatically engaging with and commenting on user content. In-the-wild detections of Silver RAT v1.0 were first observed in November 2023, although the threat actor's plans to release the tr
