In this article, we'll discuss information about the Aptos project and APT coin. What is Aptos (APT) | What is Aptos coin | What is APT coin?

What is Aptos (APT)?

Aptos is a proof-of-stake (PoS) Layer 1 blockchain that uses the Move programming language and virtual machine (MoveVM) for dApp development. APT is the native token for network fees, validator staking and governance.

Aptos blockchain designed with scalability, safety, reliability, and upgradeability as key principles, to address these challenges. The Aptos blockchain has been developed over the past three years by over 350+ developers across the globe. It offers new and novel innovations in consensus, smart contract design, system security, performance, and decentralization. The combination of these technologies will provide a fundamental building block to bring web3 to the masses:

• The Aptos blockchain natively integrates and internally uses the Move language for fast and secure transaction execution. The Move prover, a formal verifier for smart contracts written in the Move language, provides additional safeguards for contract invariants and behavior. This focus on security allows developers to better protect their software from malicious entities.
• The Aptos data model enables flexible key management and hybrid custodial options. This, alongside transaction transparency prior to signing and practical light client protocols, provides a safer and more trustworthy user experience.
• To achieve high throughput and low latency, the Aptos blockchain leverages a pipelined and modular approach for the key stages of transaction processing. Specifically, transaction dissemination, block metadata ordering, parallel transaction execution, batch storage, and ledger certification all operate concurrently. This approach fully leverages all available physical resources, improves hardware efficiency, and enables highly parallel execution.
• Unlike other parallel execution engines that break transaction atomicity by requiring upfront knowledge of the data to be read and written, the Aptos blockchain does not put such limitations on developers. It can efficiently support atomicity with arbitrarily complex transactions, enabling higher throughput and lower latency for real-world applications and simplifying development.
• The Aptos modular architecture design supports client flexibility and optimizes for frequent and instant upgrades. Moreover, to rapidly deploy new technology innovations and support new web3 use cases, the Aptos blockchain provides embedded on-chain change management protocols.
• The Aptos blockchain is experimenting with future initiatives to scale beyond individual validator performance: its modular design and parallel execution engine support internal sharding of a validator and homogeneous state sharding provides the potential for horizontal throughput scalability without adding additional complexity for node operators.

How does Aptos works?

In order to meet the dependability and safety standards set by Aptos’s vision, their blockchain is build on a few of these core principles:

• Creating a new smart smart contract programming language, Move

Move enables fast and safe execution as well as simple auditability and mechanical analyzability. It began with the forerunner of the Aptos blockchain and has continued to evolve alongside the project.

• Creating an extremely high throughput and low latency through a batched, pipelined, and parallelized approach to transaction processing.
• Provides a novel parallel transaction process

In contrast to previous parallel execution engines that need advance knowledge of data locations to be read and written, Block-STM provides novel parallel transaction processing that effectively enables atomicity with arbitrarily complicated transactions.

• Performance and decentralization optimizations are achieved by quick stake-weight validator set rotation and reputation tracking.
• Implement upgradability and configurability into their core design concepts.

I know that everything mentioned above is quite complicated. In layman terms, Aptos is the new layer 1 blockchain that is much faster, more secure and more scalable than all the current live blockchains. You can read more of their in-depth details at the white paper.

Who Are Their Competitors?

• Ethereum – The first blockchain platform particularly intended for smart contracts.
• L1 projects that have been created include Binance Smart Chain, Solana, Avalanche, and others.
• ASTAR, Moonbeam, and other early Language 1 (L1) programs
• Polygon, Arbitrum, Optimism, and other L2-related projects.
• Sui, Celestia, and other incomplete L1 initiatives

Tokenomics

The initial total supply of Aptos tokens at Monday’s mainnet launch was 1 billion, with some 510 million distributed to community members, 190 million to core developers and the remaining to the Aptos Foundation and private investors.

The Aptos Foundation holds 410 million tokens overall, which will be released over the next 10 years. Of that, 125 million APT is available initially to support ecosystem projects, grants, and unspecified community growth initiatives, and a smaller 5,000,000 APT available initially to support the Aptos Foundation initiatives for the Foundation category.

Another 100 million tokens are held by Aptos Labs, a centralized entity that develops and maintains the blockchain.

Aptos said tokens held by private investors and current core contributors are subject to a four-year lockup schedule from the mainnet launch.

There are rewards for holders who stake their tokens to contribute to the network’s upkeep. “Currently, the maximum reward rate starts at 7% annually and is evaluated at every epoch,” the post read.

“The maximum reward rate declines by 1.5% annually until a lower bound of 3.25% annually,” it added, pointing out that all transaction fees are currently burned but this may change based on future governance decisions made by the Aptos community.

Microsoft Exchange, Outlook Under Siege By APTs

New, sophisticated adversaries are switching up their tactics in exploiting enterprise-friendly platforms — most notably Microsoft Exchange, Outlook Web Access (OWA) and Outlook on the Web – in order to steal business credentials and other sensitive data.

Both Microsoft’s Exchange mail server and calendaring server and its Outlook personal information manager web app provide authentication services – and integration with other platforms – that researchers say are prime for attackers to leverage for launching attacks.

Accenture’s 2020 Cyber Threatscape report, released Monday, shed light on how actors are leveraging Exchange and OWA – and evolving their tactics to develop new malware families that target these services, or using new detection evasion techniques.

“Web-facing, data-intense systems and services that typically communicate externally can make it easier for adversaries to hide their traffic in the background noise, while authentication services could open up a credential-harvesting opportunity for cybercriminals,” according to Accenture researchers on Monday.

APTs Flock Exchange, OWA

One threat group that has been targeting Exchange and OWA is what researchers dub “BELUGASTURGEON” (aka Turla or Whitebear). Researchers say that this group operates from Russia, has been active for more than 10 years and is associated with numerous cyberattacks aimed at government agencies, foreign-policy research firms and think tanks across the globe.

The group is targeting these Microsoft services and using them as beachheads to hide traffic, relay commands, compromise e-mail, exfiltrate data and gather credentials for future espionage attacks, said researchers. For instance, they are manipulating legitimate traffic that’s traversing Exchange in order to relay commands or exfiltrate sensitive data.

“Hosts supporting Exchange and associated services frequently relay large volumes of data to external locations— representing a prime opportunity for malicious actors to hide their traffic within this background noise,” said researchers.

Another group, which researchers call SOURFACE (aka APT39 or Chafer), appears to have developed similar techniques to conceal malicious traffic, manipulating local firewalls and proxying traffic over non-standard ports using native commands, tools and functions, researchers said. Researchers said this group has been active since at least 2014 and is known for its cyberattacks on the oil and gas, communications, transportation and other industries in the Australia, Europe, Israel, Saudi Arabia, the U.S. and other regions.

In addition, threat groups are also creating new malware designed to specifically target Exchange and OWA. Researchers said they discovered several malicious files in the wild in 2019 that they assessed “with moderate confidence” were associated to a group called BLACKSTURGEON, used in targeting government and public sector orgs.

That includes a file that seemed like a version of the group’s customized version of the “RULER” tool, which is designed to abuse Microsoft Exchange services. This file exploits the CVE- 2017-11774 Outlook vulnerability, a security-feature bypass vulnerability that affects Microsoft Outlook and enables attackers to execute arbitrary commands, researchers said.

Other Services Under Attack

Cybercriminals are also targeting services that support Exchange and OWA. For instance, client-access servers (CAS), which handle all client connections to Exchange Server 2010 and Exchange 2013, typically operate in web-login portals for services including OWA. Attackers with access to CAS may be able to deploy capabilities to steal user login credentials, researchers said.

“Notably, an advanced persistent threat actor reportedly deployed web shells to harvest credentials from OWA users as they logged in,” they said.

The Windows Internet Information Services (IIS) platform, which supports OWA, is another increasing target. IIS is a web server software created by Microsoft for use with the Windows family. Researchers said they have observed SOURFACE, for instance, deploying custom Active Server Page Extended (ASPX) Web shells to IIS directories within the victim’s OWA environment. These web shells would include discrete file names, to resemble legitimate files on the victim’s system (for instance “login2.aspx” instead of “login.aspx”). And, to evade static detection, they typically contained limited functionality, often only file upload and download or command execution.

How to Install and Correct Dependencies Issues in Ubuntu

What is a Dependency?
A dependency is defined as a file, component, or software package that a program needs to work correctly. Almost every software package we install depends on another piece of code or software to work as expected. Because the overall theme of Linux has always been to have a program do one specific thing, and do it well, many software titles utilize other pieces of software to run correctly.

Introduction
Let’s review what dependencies are and why they are required. We all have, at one point or another, most certainly seen a message from our system when we were installing software regarding “missing dependencies.” This error denotes that a required part of the software package is outdated, unavailable or missing. Let’s review how to address those issues when we come across them on Ubuntu.
