The operators behind  BRATA  have once again added more capabilities to the Android mobile malware in an attempt to make their attacks against financial apps more stealthy. "In fact, the modus operandi now fits into an Advanced Persistent Threat (APT) activity pattern," Italian cybersecurity firm Cleafy  said  in a report last week. "This term is used to describe an attack campaign in which criminals establish a long-term presence on a targeted network to steal sensitive information." An acronym for "Brazilian Remote Access Tool Android," BRATA was first  detected  in the wild in Brazil in late 2018, before making its first appearance in Europe last April, while masquerading as antivirus software and other common productivity tools to trick users into downloading them. The change in the attack pattern, which scaled new highs in early April 2022, involves tailoring the malware to strike a specific financial institution at a time, switching to a differe...

Cybersecurity researchers have disclosed details about 15 security flaws in Siemens SINEC network management system (NMS), some of which could be chained by an attacker to achieve remote code execution on affected systems. "The vulnerabilities, if exploited, pose a number of risks to Siemens devices on the network including denial-of-service attacks, credential leaks, and remote code execution in certain circumstances," industrial security company Claroty  said  in a new report. The shortcomings in question — tracked from CVE-2021-33722 through CVE-2021-33736 — were addressed by Siemens in version V1.0 SP2 Update 1 as part of patches shipped on October 12, 2021. "The most severe could allow an authenticated remote attacker to execute arbitrary code on the system, with system privileges, under certain conditions," Siemens  noted  in an advisory at the time. Chief among the weaknesses is CVE-2021-33723 (CVSS score: 8.8), which allows for privilege escalation to...

The U.S. Department of Justice (DoJ) on Thursday disclosed that it took down the infrastructure associated with a Russian botnet known as RSOCKS in collaboration with law enforcement partners in Germany, the Netherlands, and the U.K. The botnet, operated by a sophisticated cybercrime organization, is believed to have ensnared millions of internet-connected devices, including Internet of Things (IoT) devices, Android phones, and computers for use as a proxy service. Botnets, a constantly evolving threat, are networks of hijacked computer devices that are under the control of a single attacking party and are used to facilitate a variety of large-scale cyber intrusions such as distributed denial-of-service (DDoS) attacks, email spam, and cryptojacking. "The RSOCKS botnet offered its clients access to IP addresses assigned to devices that had been hacked," the DoJ  said  in a press release. "The owners of these devices did not give the RSOCKS operator(s) authority to ac...

A recently patched  critical security flaw  in Atlassian Confluence Server and Data Center products is being actively weaponized in real-world attacks to drop cryptocurrency miners and ransomware payloads. In at least two of the Windows-related incidents observed by cybersecurity vendor Sophos, adversaries exploited the vulnerability to deliver Cerber ransomware and a  crypto miner  called z0miner on victim networks. The bug ( CVE-2022-26134 , CVSS score: 9.8), which was  patched  by Atlassian on June 3, 2022, enables an unauthenticated actor to inject malicious code that paves the way of remote code execution (RCE) on affected installations of the collaboration suite. All supported versions of Confluence Server and Data Center are affected. Other notable malware pushed as part of disparate instances of attack activity include Mirai and Kinsing bot variants, a rogue package called  pwnkit , and Cobalt Strike by way of a web shell deployed after ga...

An enterprise-grade surveillanceware dubbed Hermit has been put to use by entities operating from within Kazakhstan, Syria, and Italy over the years since 2019, new research has revealed. Lookout attributed the spy software, which is equipped to target both Android and iOS, to an Italian company named RCS Lab S.p.A and Tykelab Srl, a telecom services provider which it suspects to be a front company. The San Francisco-based cybersecurity firm said it detected the campaign aimed at Kazakhstan in April 2022. Hermit is modular and comes with myriad capabilities that allow it to "exploit a rooted device, record audio and make and redirect phone calls, as well as collect data such as call logs, contacts, photos, device location and SMS messages," Lookout researchers Justin Albrecht and Paul Shunk  said  in a new write-up. The spyware is believed to be distributed via SMS messages that trick users into installing what are seemingly innocuous apps from Samsung, Vivo, and Oppo, w...

It was first the pandemic that changed the usual state of work - before, it was commuting, working in the office & coming home for most corporate employees. Then, when we had to adapt to the self-isolation rules, the work moved to home offices, which completely changed the workflow for many businesses. As the pandemic went down, we realized success never relied on where the work was done. Whether your office is your kitchen, your bedroom, a nearby cafe, or your actual workplace in an office building, it all comes down to the fact that job success has nothing to do with your location.  The role of the office in the hybrid era is also changing - according to the research conducted by  PwC , it now serves the purpose of collaborating with team members and building relationships. From an employee's side, it sounds pretty logical and obvious.  However, if we look at hybrid work with the eyes of an employer, things get complicated. How does one make sure corporate device...

A sophisticated Chinese advanced persistent threat (APT) actor exploited a critical security vulnerability in Sophos' firewall product that came to light earlier this year to infiltrate an unnamed South Asian target as part of a highly-targeted attack. "The attacker implement[ed] an interesting web shell backdoor, create[d] a secondary form of persistence, and ultimately launch[ed] attacks against the customer's staff," Volexity  said  in a report. "These attacks aimed to further breach cloud-hosted web servers hosting the organization's public-facing websites." The zero-day flaw in question is tracked as  CVE-2022-1040  (CVSS score: 9.8), and concerns an authentication bypass vulnerability that can be weaponized to execute arbitrary code remotely. It affects Sophos Firewall versions 18.5 MR3 (18.5.3) and earlier. The cybersecurity firm, which issued a patch for the flaw on March 25, 2022, noted that it was abused to "target a small set of spec...

WordPress websites using a widely used plugin named Ninja Forms have been updated automatically to remediate a critical security vulnerability that's suspected of having been actively exploited in the wild. The issue, which relates to a case of code injection, is rated 9.8 out of 10 for severity and affects multiple versions starting from 3.0. It has been fixed in 3.0.34.2, 3.1.10, 3.2.28, 3.3.21.4, 3.4.34.2, 3.5.8.4, and 3.6.11. Ninja Forms is a  customizable contact form builder  that has over 1 million installations. According to Wordfence, the bug "made it possible for unauthenticated attackers to call a limited number of methods in various Ninja Forms classes, including a method that unserialized user-supplied content, resulting in Object Injection." "This could allow attackers to execute arbitrary code or delete arbitrary files on sites where a separate [property oriented programming] chain was present," Chloe Chamberland of Wordfence  noted . Suc...

Microsoft is warning that the BlackCat ransomware crew is leveraging exploits for  unpatched Exchange server  vulnerabilities to gain access to targeted networks. Upon gaining an entry point, the attackers swiftly moved to gather information about the compromised machines, followed by carrying out credential theft and lateral movement activities, before harvesting intellectual property and dropping the ransomware payload. The entire sequence of events played out over the course of two full weeks, the Microsoft 365 Defender Threat Intelligence Team  said  in a report published this week. "In another incident we observed, we found that a ransomware affiliate gained initial access to the environment via an internet-facing Remote Desktop server using compromised credentials to sign in," the researchers said, pointing out how "no two BlackCat 'lives' or deployments might look the same." BlackCat , also known by the names ALPHV and Noberus, is a relatively n...

A "dangerous piece of functionality" has been discovered in Microsoft 365 suite that could be potentially abused by a malicious actor to mount attacks on cloud infrastructure and ransom files stored on SharePoint and OneDrive. The cloud ransomware attack makes it possible to launch file-encrypting malware to "encrypt files stored on SharePoint and OneDrive in a way that makes them unrecoverable without dedicated backups or a decryption key from the attacker," Proofpoint  said  in a report published today. The infection sequence can be carried out using a combination of Microsoft APIs, command-line interface (CLI) scripts, and PowerShell scripts, the enterprise security firm added. The attack, at its core, hinges on a Microsoft 365 feature called AutoSave that creates copies of older file versions as and when users make edits to a file stored on OneDrive or SharePoint Online. It commences with gaining unauthorized access to a target user's SharePoint Online...

For years, the two most popular methods for internal scanning: agent-based and network-based were considered to be about equal in value, each bringing its own strengths to bear. However, with remote working now the norm in most if not all workplaces, it feels a lot more like agent-based scanning is a must, while network-based scanning is an optional extra. This article will go in-depth on the strengths and weaknesses of each approach, but let's wind it back a second for those who aren't sure why they should even do internal scanning in the first place. Why should you perform internal vulnerability scanning? While  external vulnerability scanning  can give a great overview of what you look like to a hacker, the information that can be gleaned without access to your systems can be limited. Some serious vulnerabilities can be discovered at this stage, so it's a must for many organizations, but that's not where hackers stop.  Techniques like phishing, targeted malware,...

Cybersecurity researchers have detailed a recently patched high-severity security vulnerability in the popular Fastjson library that could be potentially exploited to achieve remote code execution. Tracked as  CVE-2022-25845  (CVSS score: 8.1), the  issue  relates to a case of  deserialization of untrusted data  in a supported feature called "AutoType." It was patched by the project maintainers in  version 1.2.83  released on May 23, 2022. "This vulnerability affects all Java applications that rely on Fastjson versions 1.2.80 or earlier and that pass user-controlled data to either the JSON.parse or JSON.parseObject APIs without specifying a specific  class  to deserialize," JFrog's Uriya Yavnieli  said  in a write-up. Fastjson  is a Java library that's used to convert Java Objects into their  JSON  representation and vice versa.  AutoType , the function vulnerable to the flaw, is enabled by default and...

A new strain of Android malware has been spotted in the wild targeting online banking and cryptocurrency wallet customers in Spain and Italy, just weeks after a coordinated law enforcement operation dismantled  FluBot . The information stealing trojan, codenamed  MaliBot  by F5 Labs, is as feature-rich as its  counterparts , allowing it to steal credentials and cookies, bypass multi-factor authentication (MFA) codes, and abuse Android's Accessibility Service to monitor the victim's device screen. MaliBot is known to primarily disguise itself as cryptocurrency mining apps such as Mining X or The CryptoApp that are distributed via fraudulent websites designed to attract potential visitors into downloading them. It also takes another leaf out of the mobile banking trojan playbook in that it employs smishing as a distribution vector to proliferate the malware by accessing an infected smartphone's contacts and sending SMS messages containing links to the malware. "M...

Cisco on Wednesday rolled out fixes to address a critical security flaw affecting Email Security Appliance (ESA) and Secure Email and Web Manager that could be exploited by an unauthenticated, remote attacker to sidestep authentication. Assigned the CVE identifier CVE-2022-20798 , the bypass vulnerability is rated 9.8 out of a maximum of 10 on the CVSS scoring system and stems from improper authentication checks when an affected device uses Lightweight Directory Access Protocol ( LDAP ) for external authentication. "An attacker could exploit this vulnerability by entering a specific input on the login page of the affected device," Cisco noted in an advisory. "A successful exploit could allow the attacker to gain unauthorized access to the web-based management interface of the affected device." The flaw, which it said was identified during the resolution of a technical assistance center (TAC) case, impacts ESA and Secure Email and Web Manager running vulnerable ...

A new Golang-based peer-to-peer (P2P) botnet has been spotted actively targeting Linux servers in the education sector since its emergence in March 2022. Dubbed  Panchan  by Akamai Security Research, the malware "utilizes its built-in concurrency features to maximize spreadability and execute malware modules" and "harvests SSH keys to perform lateral movement." The feature-packed botnet, which relies on a basic list of default SSH passwords to carry out a  dictionary attack  and expand its reach, primarily functions as a cryptojacker designed to hijack a computer's resources to mine cryptocurrencies. The cybersecurity and cloud service company noted it first spotted Panchan's activity on March 19, 2022, and attributed the malware to a likely Japanese threat actor based on the language used in the administrative panel baked into the binary to edit the mining configuration. Panchan is known to deploy and execute two miners, XMRig and nbhash, on the host ...

A newly discovered security vulnerability in modern Intel and AMD processors could let remote attackers steal encryption keys via a power side channel attack. Dubbed  Hertzbleed  by a group of researchers from the University of Texas, the University of Illinois Urbana-Champaign, and the University of Washington, the issue is rooted in dynamic voltage and frequency scaling ( DVFS ), a power and thermal management feature employed to conserve power and reduce the amount of heat generated by a chip. "The cause is that, under certain circumstances, periodic CPU frequency adjustments depend on the current CPU power consumption, and these adjustments directly translate to execution time differences (as 1 hertz = 1 cycle per second)," the researchers said. This can have significant security implications on cryptographic libraries even when implemented correctly as  constant-time code  to prevent timing-based side channels, effectively enabling an attacker to leverage t...

Breaches don't just happen to large enterprises. Threat actors are increasingly targeting small businesses. In fact,  43%  of data breaches involved small to medium-sized businesses. But there is a glaring discrepancy. Larger businesses typically have the budget to keep their lights on if they are breached. Most small businesses ( 83% ), however, don't have the financial resources to recover if they are a victim of an attack.  These small security teams were getting lost in the shuffle...until now.  The rise of XDR  As the threat landscape changes and bad actors continue to evolve their tactics, the industry is responding with new solutions and approaches to the way we do cybersecurity. The most recent evolution of cybersecurity technology is extended detection and response (XDR). There's no doubt you've heard of it. But do you have a firm grasp on what it really is and its unique value? If you shook your head "no" – you aren't alone. Industry exper...
