A new, multi-functional Go-based malware dubbed  Chaos  has been rapidly growing in volume in recent months to ensnare a wide range of Windows, Linux, small office/home office (SOHO) routers, and enterprise servers into its botnet. "Chaos functionality includes the ability to enumerate the host environment, run remote shell commands, load additional modules, automatically propagate through stealing and brute-forcing SSH private keys, as well as launch DDoS attacks," researchers from Lumen's Black Lotus Labs  said  in a write-up shared with The Hacker News. A majority of the bots are located in Europe, specifically Italy, with other infections reported in China and the U.S., collectively representing "hundreds of unique IP addresses" over a one-month time period from mid-June through mid-July 2022. Written in Chinese and leveraging China-based infrastructure for command-and-control, the botnet joins a long list of malware that are designed to establish persi...

A recently discovered malware builder called Quantum Builder is being used to deliver the Agent Tesla remote access trojan (RAT). "This campaign features enhancements and a shift toward LNK (Windows shortcut) files when compared to similar attacks in the past," Zscaler ThreatLabz researchers Niraj Shivtarkar and Avinash Kumar  said  in a Tuesday write-up. Sold on the dark web for €189 a month,  Quantum Builder  is a customizable tool for generating malicious shortcut files as well as HTA, ISO, and PowerShell payloads to deliver next-stage malware on the targeted machines, in this case  Agent Tesla . The multi-stage attack chain starts with a spear-phishing email containing a GZIP archive attachment that includes a shortcut designed to execute PowerShell code responsible for launching a remote HTML application (HTA) using  MSHTA . The phishing emails purport to be an order confirmation message from a Chinese supplier of lump and rock sugar, with the L...

Organizations struggle to find ways to keep a good security posture. This is because it is difficult to create secure system policies and find the right tools that help achieve a good posture. In many cases, organizations work with tools that do not integrate with each other and are expensive to purchase and maintain. Security posture management is a term used to describe the process of identifying and mitigating security misconfigurations and compliance risks in an organization. To maintain a good security posture, organizations should at least do the following: Maintain inventory:  Asset inventory is considered first because it provides a comprehensive list of all IT assets that should be protected. This includes the hardware devices, applications, and services that are being used. Perform vulnerability assessment:  The next step is to perform a vulnerability assessment to identify weaknesses in applications and services. Knowledge of the vulnerabilities help to priorit...

The Russian state-sponsored threat actor known as  APT28  has been found leveraging a new code execution method that makes use of mouse movement in decoy Microsoft PowerPoint documents to deploy malware. The technique "is designed to be triggered when the user starts the presentation mode and moves the mouse," cybersecurity firm Cluster25  said  in a technical report. "The code execution runs a PowerShell script that downloads and executes a dropper from OneDrive." The dropper, a seemingly harmless image file, functions as a pathway for a follow-on payload, a variant of a malware known as Graphite, which uses the Microsoft Graph API and OneDrive for command-and-control (C2) communications to retrieve additional payloads. The attack employs a lure document that makes use of a template potentially linked to the Organisation for Economic Co-operation and Development ( OECD ), a Paris-based intergovernmental entity. Cluster25 noted the attacks may be ongoing, con...

Meta Platforms on Tuesday disclosed it took steps to dismantle two covert influence operations originating from China and Russia for engaging in coordinated inauthentic behavior (CIB) so as to manipulate public debate. While the Chinese operation sets its sights on the U.S. and the Czech Republic, the Russian network primarily targeted Germany, France, Italy, Ukraine and the U.K. with themes surrounding the ongoing war in Ukraine. "The largest and most complex Russian operation we've disrupted since the war in Ukraine began, it ran a sprawling network of over 60 websites impersonating news organizations, as well as accounts on Facebook, Instagram, YouTube, Telegram, Twitter, Change.org and Avaaz, and even LiveJournal," the social media behemoth  said . The sophisticated Russian activity, which commenced in May 2022, impersonated mainstream European news outlets like Der Spiegel, The Guardian, and Bild, not to mention build credibility by creating fake accounts across...

WhatsApp has released  security updates  to address two flaws in its messaging app for Android and iOS that could lead to remote code execution on vulnerable devices. One of them concerns  CVE-2022-36934  (CVSS score: 9.8), a critical integer overflow vulnerability in WhatsApp that results in the execution of arbitrary code simply by establishing a video call. The issue impacts the WhatsApp and WhatsApp Business for Android and iOS prior to versions 2.22.16.12. Also patched by the Meta-owned messaging platform is an integer underflow bug, which refers to an opposite category of errors that occur when the result of an operation is too small for storing the value within the allocated memory space. The high-severity issue, given the CVE identifier  CVE-2022-27492  (CVSS score: 7.8), affects WhatsApp for Android prior to versions 2.22.16.2 and WhatsApp for iOS version 2.22.15.9, and could be triggered upon receiving a specially crafted video file. Exploi...

The Ukrainian government on Monday warned of "massive cyberattacks" by Russia targeting critical infrastructure facilities located in the country and that of its allies. The attacks are said to be targeting the energy sector, the Main Directorate of Intelligence of the Ministry of Defense of Ukraine (GUR) said. "By the cyberattacks, the enemy will try to increase the effect of missile strikes on electricity supply facilities, primarily in the eastern and southern regions of Ukraine," the agency  said  in a brief advisory. GUR also cautioned of intensified distributed denial-of-service (DDoS) attacks aimed at the critical infrastructure of Ukraine's closest allies, chiefly Poland and the Baltic states of Estonia, Latvia, and Lithuania. It's not immediately clear what prompted the intelligence agency to issue the notice, but Ukraine has been at the receiving end of  disruptive and destructive cyberattacks  since the onset of the Russo-Ukrainian war earli...

Cybercriminals are continuing to prey on users searching for cracked software by directing them to fraudulent websites hosting weaponized installers that deploy malware called  NullMixer  on compromised systems. "When a user extracts and executes NullMixer, it drops a number of malware files to the compromised machine," cybersecurity firm Kaspersky said in a Monday report. "It drops a wide variety of malicious binaries to infect the machine with, such as backdoors, bankers, downloaders, spyware, and many others." Besides siphoning users' credentials, address, credit card data, cryptocurrencies, and even Facebook and Amazon account session cookies, what makes NullMixer insidious is its ability to download dozens of trojans at once, significantly widening the scale of the infections. Attack chains typically start when a user attempts to download cracked software from one of the sites, which leads to a password-protected archive that contains an executable fil...

As many as 75 apps on Google Play and 10 on Apple App Store have been discovered engaging in ad fraud as part of an ongoing campaign that commenced in 2019. The latest iteration, dubbed  Scylla  by Online fraud-prevention firm HUMAN Security, follows similar attack waves in August 2019 and late 2020 that go by the codename Poseidon and Charybdis, respectively. Prior to their removal from the app storefronts, the apps had been collectively installed more than 13 million times. The original Poseidon operation comprised over 40 Android apps that were designed to display ads out of context or hidden from the view of the device user. Charybdis, on the other hand, was an improvement over the former by making use of code obfuscation tactics to target advertising platforms. Scylla presents the latest adaption of the scheme in that it expands beyond Android to make a foray into the iOS ecosystem for the first time, alongside relying on additional layers of code roundabout using...

The global cybersecurity market is flourishing. Experts at Gartner predict that the end-user spending for the information security and risk management market will grow from $172.5 billion in 2022 to $267.3 billion in 2026.  One big area of spending includes the art of putting cybersecurity defenses under pressure, commonly known as security testing. MarketsandMarkets forecasts the global penetration testing (pentesting) market size is expected to grow at a Compound Annual Growth Rate (CAGR) of 13.7% from 2022 to 2027. However, the costs and limitations involved in carrying out a penetration test are already hindering the market growth, and consequently, many cybersecurity professionals are making moves to find an alternative solution. Pentests aren't solving cybersecurity pain points Pentesting can serve specific and important purposes for businesses. For example, prospective customers may ask for the results of one as proof of compliance. However, for certain challenges, this ...

The infamous Lazarus Group has continued its pattern of leveraging unsolicited job opportunities to deploy malware targeting Apple's macOS operating system. In the latest variant of the campaign observed by cybersecurity company SentinelOne last week, decoy documents advertising positions for the Singapore-based cryptocurrency exchange firm Crypto[.]com have been used to mount the attacks. The latest disclosure builds on previous findings from Slovak cybersecurity firm ESET in August, which  delved  into a similar phony job posting for the Coinbase cryptocurrency exchange platform. Both these fake job advertisements are just the latest in a series of attacks dubbed  Operation In(ter)ception , which, in turn, is a constituent of a broader campaign tracked under the name  Operation Dream Job . Although the exact distribution vector for the malware remains unknown, it's suspected that potential targets are singled out via direct messages on the business networking...

The Australian Federal Police (AFP) on Monday disclosed it's working to gather "crucial evidence" and that it's collaborating with overseas law enforcement authorities following the hack of telecom provider Optus. "Operation Hurricane has been launched to identify the criminals behind the alleged breach and to help shield Australians from identity fraud," the AFP  said  in a statement. The development comes after Optus, Australia's second-largest wireless carrier,  disclosed  on September 22, 2022, that it was a victim of a cyberattack. It claimed it "immediately shut down the attack" as soon as it came to light. The threat actor behind the breach also briefly released a sample of 10,200 records from the breach – putting those users at heightened risk of fraud – in addition to asking for $1 million as part of an extortion demand. The dataset has since been taken down, with the attacker also claiming to have deleted the only copy of the sto...
