Cybersecurity researchers on Monday took the wraps off a new Android trojan that takes advantage of accessibility features on mobile devices to siphon credentials from banking and cryptocurrency services in Italy, the U.K., and the U.S. Dubbed " SharkBot " by Cleafy, the malware is designed to strike a total of 27 targets — counting 22 unnamed international banks in Italy and the U.K. as well as five cryptocurrency apps in the U.S. — at least since late October 2021 and is believed to be in its early stages of development, with no overlaps found to that of any known families. "The main goal of SharkBot is to initiate money transfers from the compromised devices via Automatic Transfer Systems (ATS) technique bypassing multi-factor authentication mechanisms (e.g., SCA)," the researchers said in a report. "Once SharkBot is successfully installed in the victim's device, attackers can obtain sensitive banking information through the abuse of Accessibility S...

A new analysis of website fingerprinting (WF) attacks aimed at the Tor web browser has revealed that it's possible for an adversary to glean a website frequented by a victim, but only in scenarios where the threat actor is interested in a specific subset of the websites visited by users. "While attacks can exceed 95% accuracy when monitoring a small set of five popular websites, indiscriminate (non-targeted) attacks against sets of 25 and 100 websites fail to exceed an accuracy of 80% and 60%, respectively," researchers Giovanni Cherubin, Rob Jansen, and Carmela Troncoso  said  in a newly published paper. Tor browser  offers  "unlinkable communication" to its users by routing internet traffic through an overlay network, consisting of more than six thousand relays, with the goal of anonymizing the originating location and usage from third parties conducting network surveillance or traffic analysis. It achieves this by building a circuit that traverses via an ...

Lazarus, the North Korea-affiliated state-sponsored group, is attempting to once again target security researchers with backdoors and remote access trojans using a trojanized pirated version of the popular IDA Pro reverse engineering software. The findings were  reported  by ESET security researcher Anton Cherepanov last week in a series of tweets. IDA Pro is an  Interactive Disassembler  that's designed to translate machine language (aka executables) into assembly language, enabling security researchers to analyze the inner workings of a program (malicious or otherwise) as well as function as a debugger to detect errors. "Attackers bundled the original IDA Pro 7.5 software developed by [Hex-Rays] with two malicious components," the Slovak cybersecurity firm said, one of which is an internal module called "win_fw.dll" that's executed during installation of the application. This tampered version is then orchestrated to load a second component named ...

Whether it's Office 365, Salesforce, Slack, GitHub or Zoom, all SaaS apps include a host of security features designed to protect the business and its data. The job of ensuring these apps' security settings are properly configured falls on the security team. The challenge lies within how burdensome this responsibility is — each app has tens or hundreds of security settings to configure, in addition to the continuous need for general or user updates, compounded by many compliance industry standards and frameworks that organizations need to follow. Not to mention the fact that often the SaaS app owner sits outside the outside of the security team in the department that most uses the app (think Sales has CRM app, Marketing has automation app), and they are untrained and not focused on the security upkeep of the app. It all amounts to just how unrealistic it is to expect security teams to be able to stay in control of the organization's SaaS stack.  That's why Gartner n...

The U.S. Federal Bureau of Investigation (FBI) on Saturday confirmed unidentified threat actors have breached one of its email servers to blast hoax messages about a fake "sophisticated chain attack." The incident, which was first  publicly disclosed  by threat intelligence non-profit SpamHaus, involved sending rogue warning emails with the subject line "Urgent: Threat actor in systems" originating from a legitimate FBI email address "eims@ic.fbi[.]gov" that framed the attack on Vinny Troia, a security researcher and founder of dark web intelligence firms Night Lion Security and Shadowbyte, while also claiming him to be affiliated with a hacking outfit named TheDarkOverlord. SpamHaus cited its own telemetry data to point out that the email blasts happened over two "spam" waves, one shortly before 5:00 a.m. UTC and another one shortly after 7:00 a.m. UTC.  However, according to Kryptos Logic researcher Marcus Hutchins, the goal appears to be ...

Threat actors are increasingly banking on the technique of  HTML smuggling  in phishing campaigns as a means to gain initial access and deploy an array of threats, including banking malware, remote administration trojans (RATs), and ransomware payloads. Microsoft 365 Defender Threat Intelligence Team, in a new report published Thursday, disclosed that it identified infiltrations distributing the  Mekotio  banking Trojan, backdoors such as  AsyncRAT  and  NjRAT , and the infamous  TrickBot  malware. The multi-staged attacks — dubbed  ISOMorph  — were also publicly documented by Menlo Security in July 2021. HTML smuggling is an approach that allows an attacker to "smuggle" first-stage droppers, often encoded malicious scripts embedded within specially-crafted HTML attachments or web pages, on a victim machine by taking advantage of basic features in HTML5 and JavaScript rather than exploiting a vulnerability or a design flaw in mo...

Researchers from Qihoo 360's Netlab security team have released details of a new evolving botnet called " Abcbot " that has been observed in the wild with worm-like propagation features to infect Linux systems and launch distributed denial-of-service (DDoS) attacks against targets. While the earliest version of the botnet dates back to July 2021, new variants observed as recently as October 30 have been equipped with additional updates to strike Linux web servers with weak passwords and are susceptible to N-day vulnerabilities, including a custom implementation of DDoS functionality, indicating that the malware is under continuous development. Netlab's findings also build on a report from Trend Micro early last month, which  publicized  attacks targeting Huawei Cloud with cryptocurrency-mining and cryptojacking malware. The intrusions were also notable for the fact that the malicious shell scripts specifically disabled a process designed to monitor and scan the ser...
