Did you know it's now possible to build blockchain applications, known also as decentralized applications (or "dApps" for short) in native Python? Blockchain development has traditionally required learning specialized languages, creating a barrier for many developers… until now. AlgoKit , an all-in-one development toolkit for Algorand, enables developers to build blockchain applications in pure Python. This article will walk you through the benefits of building blockchain applications, why Python is an ideal choice for dApp development, how to set up your blockchain development environment, and how to start building secure blockchain applications in native Python.  Why build blockchain applications?  Blockchain application development goes far beyond creating a decentralized database and peer-to-peer transactions. It unlocks a new level of trust, security, and efficiency for various applications. Guarantee tamper-proof records: Blockchain creates an immutable and transparent ledge

Cybersecurity researchers have discovered a targeted operation against Ukraine that has been found leveraging a nearly seven-year-old flaw in Microsoft Office to deliver Cobalt Strike on compromised systems. The attack chain, which took place at the end of 2023 according to Deep Instinct, employs a PowerPoint slideshow file ("signal-2023-12-20-160512.ppsx") as the starting point, with the filename implying that it may have been shared via the Signal instant messaging app. That having said, there is no actual evidence to indicate that the PPSX file was distributed in this manner, even though the Computer Emergency Response Team of Ukraine (CERT-UA) has uncovered  two different campaigns  that have used the  messaging app  as a  malware delivery vector  in the past. Just last week, the agency  disclosed  that Ukrainian armed forces are being increasingly targeted by the UAC-0184 group via messaging and dating platforms to serve malware like  HijackLoader  (aka  GHOSTPULSE  

Imagine you could gain access to any Fortune 100 company for $10 or less, or even for free. Terrifying thought, isn't it? Or exciting, depending on which side of the cybersecurity barricade you are on. Well, that's basically the state of things today. Welcome to the infostealer garden of low-hanging fruit. Over the last few years, the problem has grown bigger and bigger, and only now are we slowly learning its full destructive potential. In this article, we will describe how the entire cybercriminal ecosystem operates, the ways various threat actors exploit data originating from it, and most importantly, what you can do about it. Let's start with what infostealer malware actually is. As the name suggests, it's malware that... steals data. Depending on the specific type, the information it extracts might differ slightly, but most will try to extract the following: Cryptocurrency wallets Bank account information and saved credit card details Saved passwords from various apps Bro

In a world where more & more organizations are adopting open-source components as foundational blocks in their application's infrastructure, it's difficult to consider traditional SCAs as complete protection mechanisms against open-source threats. Using open-source libraries saves tons of coding and debugging time, and by that - shortens the time to deliver our applications. But, as codebases become increasingly composed of open-source software, it's time to respect the entire attack surface - including attacks on the supply chain itself - when choosing an  SCA platform  to depend upon. The Impact of One Dependency When a company adds an open-source library, they are probably adding not just the library they intended to, but also many other libraries as well. This is due to the way open-source libraries are built: just like every other application on the planet, they aim for a speed of delivery and development and, as such, rely on code other people built - i.e., ot

Pirated applications targeting Apple macOS users have been observed containing a backdoor capable of granting attackers remote control to infected machines. "These applications are being hosted on Chinese pirating websites in order to gain victims," Jamf Threat Labs researchers Ferdous Saljooki and Jaron Bradley  said . "Once detonated, the malware will download and execute multiple payloads in the background in order to secretly compromise the victim's machine." The backdoored disk image (DMG) files, which have been modified to establish communications with actor-controlled infrastructure, include legitimate software like Navicat Premium, UltraEdit, FinalShell, SecureCRT, and Microsoft Remote Desktop. The unsigned applications, besides being hosted on a Chinese website named macyy[.]cn, incorporate a dropper component called "dylib" that's executed every time the application is opened. The dropper then acts as a conduit to fetch a backdoor

Multiple security vulnerabilities have been disclosed in the TCP/IP network protocol stack of an open-source reference implementation of the Unified Extensible Firmware Interface ( UEFI ) specification used widely in modern computers. Collectively dubbed  PixieFail  by Quarkslab, the  nine issues  reside in the TianoCore EFI Development Kit II ( EDK II ) and could be exploited to achieve remote code execution, denial-of-service (DoS), DNS cache poisoning, and leakage of sensitive information. UEFI firmware – which is responsible for  booting the operating system  – from AMI, Intel, Insyde, and Phoenix Technologies are impacted by the shortcomings. EDK II incorporates its own TCP/IP stack called  NetworkPkg  to enable network functionalities available during the initial Preboot eXecution Environment ( PXE , pronounced "pixie") stage, which allows for management tasks in the absence of a running operating system. In other words, it is a client-server interface to  boot a

Iranian nation-state groups have now joined financially motivated actors in actively exploiting a critical flaw in PaperCut print management software, Microsoft disclosed over the weekend. The tech giant's threat intelligence team said it observed both Mango Sandstorm (Mercury) and Mint Sandstorm (Phosphorus) weaponizing CVE-2023-27350 in their operations to achieve initial access. "This activity shows Mint Sandstorm's continued ability to  rapidly incorporate [proof-of-concept] exploits  into their operations," Microsoft  said  in a series of tweets. On the other hand, CVE-2023-27350 exploitation activity associated with Mango Sandstorm is said to be on the lower end of the spectrum, with the state-sponsored group "using tools from prior intrusions to connect to their C2 infrastructure." It's worth noting that  Mango Sandstorm  is linked to Iran's Ministry of Intelligence and Security (MOIS) and  Mint Sandstorm  is associated with the Islamic

Less than a month ago, Twitter indirectly acknowledged that some of its source code had been leaked on the code-sharing platform GitHub by sending a copyright infringement notice to take down the incriminated repository. The latter is now inaccessible, but according to the media, it was accessible to the public for several months. A user going by the name FreeSpeechEnthousiast committed thousands of documents belonging to the social media platform over several months.  While there is no concrete evidence to support this hypothesis, the timing of the leak and the ironic username used by the perpetrator suggest that the leak was a deliberate act aimed at causing harm to the company. Although it is still too early to measure the impact of this leak on the health of Twitter, this incident should be an opportunity for all software vendors to ask a simple question:  what if this happened to us? Protecting sensitive information in the software industry is becoming increasingly critical as

3CX said it's  working on a software update  for its desktop app after multiple cybersecurity vendors sounded the alarm on what appears to be an active supply chain attack that's using digitally signed and rigged installers of the popular voice and video conferencing software to target downstream customers. "The trojanized 3CX desktop app is the first stage in a multi-stage attack chain that pulls ICO files appended with Base64 data from GitHub and ultimately leads to a third-stage infostealer DLL," SentinelOne researchers  said . The cybersecurity firm is tracking the activity under the name SmoothOperator , stating the threat actor registered a massive attack infrastructure as far back as February 2022. There are indications that the attack may have commenced around March 22, 2023. 3CX, the company behind 3CXDesktopApp,  claims  to have more than 600,000 customers and 12 million users in 190 countries, some of which include well-known names like American Expres

A coalition of law enforcement agencies across Europe and the U.S.  announced  the takedown of ChipMixer, an unlicensed cryptocurrency mixer that began its operations in August 2017. "The ChipMixer software blocked the blockchain trail of the funds, making it attractive for cybercriminals looking to launder illegal proceeds from criminal activities such as drug trafficking, weapons trafficking, ransomware attacks, and payment card fraud," Europol  said  in a statement. The coordinated exercise, besides dismantling the clearnet and dark web websites associated with ChipMixer, also resulted in the seizure of $47.5 million in Bitcoin and 7 TB of data. Mixers, also called tumblers,  offer full anonymity  for a fee by commingling cryptocurrency from different users – both legitimate and criminally-derived funds – in a manner that makes it hard to trace the origins. This is achieved by funneling different payments into a single pool before splitting up each amount and transmit

Threat actors have been increasingly observed using AI-generated YouTube Videos to spread a variety of stealer malware such as Raccoon, RedLine, and Vidar. "The videos lure users by pretending to be tutorials on how to download cracked versions of software such as Photoshop, Premiere Pro, Autodesk 3ds Max, AutoCAD, and other products that are licensed products available only to paid users," CloudSEK researcher Pavan Karthick M  said . Just as the ransomware landscape comprises core developers and affiliates who are in charge of identifying potential targets and actually carrying out the attacks, the information stealer ecosystem also consists of threat actors known as  traffers  who are recruited to spread the malware using different methods. One of the popular malware distribution channels is YouTube, with CloudSEK witnessing a 200-300% month-over-month increase in videos containing links to stealer malware in the description section since November 2022. These links ar

The operators of RomCom RAT malware are continuing to evolve their campaigns by distributing rogue versions of software such as SolarWinds Network Performance Monitor, KeePass password manager, and PDF Reader Pro via fake copycat websites. Targets of the operation consist of victims in Ukraine and select English-speaking countries like the U.K. To be noted, the malicious software in question is not related to any product developed or released by SolarWinds, and is instead an unlicensed, "cracked" version of an old product. "Given the geography of the targets and the current geopolitical situation, it's unlikely that the RomCom RAT threat actor is cybercrime-motivated," the BlackBerry Threat Research and Intelligence Team  said  in a new analysis. The latest findings  come  a week after the Canadian cybersecurity company disclosed a spear-phishing campaign aimed at Ukrainian entities to deploy a remote access trojan called RomCom RAT. The unknown threat ac

Professional developers want to do the right thing, but in terms of security, they are rarely set up for success. Organizations must support their upskilling with precision training and incentives if they want secure software from the ground up. The cyber threat landscape grows more complex by the day, with our data widely considered highly desirable "digital gold". Attackers are constantly scanning networks for vulnerable applications, programs, cloud instances, and the latest flavor of the month is APIs, with Gartner  correctly predicting  that they would become the most common attack vector in 2022, and that is in no small part thanks to their often lax security controls.  Threat actors are so persistent that new apps can sometimes be compromised and exploited within hours of deployment. The  Verizon 2022 Data Breach Investigations Report  reveals that errors and misconfigurations were the cause of 13% of breaches, with the human element responsible overall for 82% of the 23,000

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued a new Binding Operational Directive (BOD) that directs federal agencies in the country to keep track of assets and vulnerabilities on their networks six months from now. To that end, Federal Civilian Executive Branch (FCEB) enterprises have been tasked with two sets of activities: Asset discovery and vulnerability enumeration, which are seen as essential steps to gain "greater visibility into risks facing federal civilian networks." This  involves  carrying out automated asset discovery every seven days and initiating vulnerability enumeration across those discovered assets every 14 days by April 3, 2023, in addition to having the capabilities to do so on an on-demand basis within 72 hours of receiving a request from CISA. Similar baseline vulnerability enumeration obligations have also been put in place for Android and iOS devices as well as other devices that reside outside of agency on-premise

Now more than ever, organizations need to enable their development teams to build and grow their security skills. Today organizations face a threat landscape where individuals, well-financed syndicates, and state actors are actively trying to exploit errors in software. Yet, according to recent global research, 67% of developers that were interviewed said they were still shipping code they knew contained vulnerabilities.  Helping your development teams progress to achieve security maturity is possible, and ultimately beneficial. It will help ensure secure software development at every stage of the software development lifecycle. But how can you help your development teams reach security maturity? We dug deep and leveraged insights from over 400 of our customers to identify traits and behaviors that occur when a development team increases its security maturity. Here we share two of them: #1: A deep understanding of your gaps Before creating any maturity program, we first need to u

Researchers have disclosed details about a security vulnerability in the Netwrix Auditor application that, if successfully exploited, could lead to arbitrary code execution on affected devices.  "Since this service is typically executed with extensive privileges in an Active Directory environment, the attacker would likely be able to compromise the Active Directory domain," Bishop Fox  said  in an advisory published this week. Auditor  is an auditing and visibility platform that enables organizations to have a consolidated view of their IT environments, including Active Directory, Exchange, file servers, SharePoint, VMware, and other systems—all from a single console. Netwrix, the company behind the software, claims more than 11,500 customers across over 100 countries, such as Airbus, Virgin, King's College Hospital, and Credissimo, among others. The flaw, which impacts all supported versions prior to 10.5, has been described as an  insecure object deserialization
