Phishing attacks are steadily becoming more sophisticated, with cybercriminals investing in new ways of deceiving victims into revealing sensitive information or installing malicious software. One of the latest trends in phishing is the use of QR codes, CAPTCHAs, and steganography. See how they are carried out and learn to detect them. Quishing Quishing, a phishing technique resulting from the combination of "QR" and "phishing," has become a popular weapon for cybercriminals in 2023. By concealing malicious links within QR codes, attackers can evade traditional spam filters, which are primarily geared towards identifying text-based phishing attempts. The inability of many security tools to decipher the content of QR codes further makes this method a go-to choice for cybercriminals. An email containing a QR code with a malicious link Analyzing a QR code with an embedded malicious link in a safe environment is easy with  ANY.RUN : Simply open  this task  in th...

The  Kinsing  threat actors are actively exploiting a critical security flaw in vulnerable Apache ActiveMQ servers to infect Linux systems with cryptocurrency miners and rootkits. "Once Kinsing infects a system, it deploys a cryptocurrency mining script that exploits the host's resources to mine cryptocurrencies like Bitcoin, resulting in significant damage to the infrastructure and a negative impact on system performance," Trend Micro security researcher Peter Girnus  said . Kinsing  refers to a  Linux malware  with a history of targeting misconfigured containerized environments for cryptocurrency mining, often utilizing compromised server resources to generate illicit profits for the threat actors. The group is also known to quickly adapt its tactics to include newly disclosed flaws in web applications to breach target networks and deliver crypto miners. Earlier this month, Aqua  disclosed  the threat actor's attempts to exploit a Linux pri...

Android smartphone users in India are the target of a new malware campaign that employs social engineering lures to install fraudulent apps that are capable of harvesting sensitive data. "Using social media platforms like WhatsApp and Telegram, attackers are sending messages designed to lure users into installing a malicious app on their mobile device by impersonating legitimate organizations, such as banks, government services, and utilities," Microsoft threat intelligence researchers Abhishek Pustakala, Harshita Tripathi, and Shivang Desai  said  in a Monday analysis. The ultimate goal of the operation is to capture banking details, payment card information, account credentials, and other personal data. The attack chains involve sharing malicious APK files via social media messages sent on WhatsApp and Telegram by falsely presenting them as banking apps and inducing a sense of urgency by claiming that the targets' bank accounts will be blocked unless they update their pe...

The China-linked Mustang Panda actor has been linked to a cyber attack targeting a Philippines government entity amid  rising tensions  between the two countries over the disputed South China Sea. Palo Alto Networks Unit 42 attributed the adversarial collective to three campaigns in August 2023, primarily singling out organizations in the South Pacific. "The campaigns leveraged legitimate software including Solid PDF Creator and SmadavProtect (an Indonesian-based antivirus solution) to sideload malicious files," the company  said . "Threat authors also creatively configured the malware to impersonate legitimate Microsoft traffic for command-and-control (C2) connections." Mustang Panda, also tracked under the names Bronze President, Camaro Dragon, Earth Preta, RedDelta, and Stately Taurus, is assessed to be a Chinese advanced persistent threat (APT) active since at least 2012,  orchestrating   cyber espionage   campaigns  targeting non-governmenta...

Threat actors are targeting the education, government and business services sectors with a remote access trojan called  NetSupport RAT . "The delivery mechanisms for the NetSupport RAT encompass fraudulent updates, drive-by downloads, utilization of malware loaders (such as  GHOSTPULSE ), and various forms of phishing campaigns," VMware Carbon Black researchers said in a report shared with The Hacker News. The cybersecurity firm said it detected no less than 15 new infections related to NetSupport RAT in the last few weeks.  While NetSupport Manager started off as a  legitimate remote administration tool  for technical assistance and support, malicious actors have misappropriated the tool to their own advantage, using it as a beachhead for subsequent attacks. NetSupport RAT is typically downloaded onto a victim's computer via deceptive websites and fake browser updates. In August 2022, Sucuri  detailed  a campaign in which compromised WordPress...

Phishing campaigns delivering malware families such as DarkGate and PikaBot are following the same tactics previously used in attacks leveraging the now-defunct QakBot trojan. "These include hijacked email threads as the initial infection, URLs with unique patterns that limit user access, and an infection chain nearly identical to what we have seen with QakBot delivery," Cofense  said  in a report shared with The Hacker News. "The malware families used also follow suit to what we would expect QakBot affiliates to use." QakBot, also called QBot and Pinkslipbot, was  shut down  as part of a coordinated law enforcement effort codenamed Operation Duck Hunt earlier this August. The use of DarkGate and PikaBot in these campaigns is not surprising as they can both act as conduits to deliver additional payloads to compromised hosts, making them both an attractive option for cybercriminals. PikaBot's parallels to QakBot were  previously highlighted  by Zscale...

In this article, we will provide a brief overview of Silverfort's platform, the first (and currently only) unified identity protection platform on the market. Silverfort's patented technology aims to protect organizations from identity-based attacks by integrating with existing identity and access management solutions, such as AD (Active Directory) and cloud-based services, and extending secure access controls like Risk-Based Authentication and MFA (Multi-Factor Authentication) to all their resources. This includes on-prem and cloud resources, legacy systems, command-line tools and service accounts. A recent report by Silverfort and Osterman Research revealed that  83% of organizations worldwide have experienced data breaches due to compromised credentials . Many organizations admit that they are underprotected against identity-based attacks, such as lateral movement and ransomware. Resources like command-line access tools and legacy systems, which are widely used, are particular...

Today's security leaders must manage a constantly evolving attack surface and a dynamic threat environment due to interconnected devices, cloud services, IoT technologies, and hybrid work environments. Adversaries are constantly introducing new attack techniques, and not all companies have internal Red Teams or unlimited security resources to stay on top of the latest threats. On top of that, today's attackers are indiscriminate and every business - big or small - needs to be prepared. It is no longer enough for security teams to  detect and respond ; we must now also  predict and prevent . To handle today's security environment, defenders need to be agile and innovative. In short, we need to start thinking like a hacker.  Taking the mindset of an opportunistic threat actor allows you to not only gain a better understanding of potentially exploitable pathways, but also to more effectively prioritize your remediation efforts. It also helps you move past potentially harm...

The stealer malware known as  LummaC2  (aka Lumma Stealer) now features a new anti-sandbox technique that leverages the mathematical principle of trigonometry to evade detection and exfiltrate valuable information from infected hosts. The method is designed to "delay detonation of the sample until human mouse activity is detected," Outpost24 security researcher Alberto Marín  said  in a technical report shared with The Hacker News. Written in the C programming language, LummaC2 has been sold in underground forums since December 2022. The malware has since  received   iterative updates  that make it harder to analyze via control flow flattening and even allow it to deliver additional payloads. The current version of LummaC2 (v4.0) also requires its customers to use a  crypter  as an added concealing mechanism, not to mention prevent it from being leaked in its raw form. Another noteworthy update is the reliance on trigonometry to detect ...

Bitcoin wallets created between 2011 and 2015 are susceptible to a new kind of exploit called  Randstorm  that makes it possible to recover passwords and gain unauthorized access to a multitude of wallets spanning several blockchain platforms. "Randstorm() is a term we coined to describe a collection of bugs, design decisions, and API changes that, when brought in contact with each other, combine to dramatically reduce the quality of random numbers produced by web browsers of a certain era (2011-2015)," Unciphered  disclosed  in a report published last week. It's estimated that approximately 1.4 million bitcoins are parked in wallets that were generated with potentially weak cryptographic keys. Customers can check whether their wallets are vulnerable at www.keybleed[.]com. The cryptocurrency recovery company said it re-discovered the problem in January 2022 while it was  working for an unnamed customer  who had been locked out of its Blockchain.co...
