Spear phishing is a targeted attack that uses information from social media, work emails, and other sources to launch a one-on-one phishing attack against an individual.

Spear phishing is more dangerous than mass phishing because it uses your personal information (for example, your interest) to gain your trust. This technique is used mostly by cybercriminals to gather information about your organization so they can exploit vulnerabilities and cause maximum disruption.

The biggest threat of spear-phishing is the damage that it inflicts on the reputation of your business. Whether it's a fake CEO email asking for personal details, spoofing a supplier to gain access to their systems, or tricking staff into installing malware on their computer, every instance of spear-phishing can leave staff feeling anxious and vulnerable. In some cases, they get too embarrassed to admit that they fell for a scam, which means the issue could be overlooked and remain undetected for a long period of time.

How to Save Yourself from Spear Phishing?

Spear phishing is a targeted form of phishing. If you receive an email from someone you barely know requesting sensitive personal information, don't give it out. These emails are usually not sent randomly. The sender may know the person they are trying to scam, including their personal details and interests. They might even know their phone number and address.

Spear phishing can also target people in an organization, such as employees in a particular department or company executives. These attackers usually pretend to be someone whom your business deals with on a regular basis, such as a supplier or customer. Therefore, you should open all types of emails with caution.

Here are some of the steps you can take to prevent spear phishing:

- The foremost thing is to seek awareness regarding cyberattacks and phishing. Organizations need to ensure that they organized education and awareness programs for employees, teaching them how to spot strange links, protect passwords, use social media carefully, and identify suspicious emails.

- To supplement awareness and education, ensure the use of solid email security software. Such software identifies and blocks phishing emails and other cyberattacks.

- No matter how aware and cautious you are, there is a possibility that you will end up being its victim. It is always recommended to create a full backup of your data in an external hard drive, USB, or cloud storage.

- Always use updated versions of software. Hackers constantly improve their methods to get access somehow, which is why it is crucial to ensure top-notch safety by regularly updating your software and installing new security patches.

A SPAC, or a special purpose acquisition company, is a company set up by investors with the purpose of raising money through an IPO (initial public offering). SPACs have no commercial operations and are formed with the purpose of acquiring an existing company. They are generally formed by a group of investors, known as “sponsors”, where they have the intention of pursuing deals in a particular industry.
The money SPACs raise in an IPO is locked in an interest-bearing trust account where it cannot be disbursed except to complete an acquisition or to return the money to investors if the SPAC is liquidated. They act as an interface between the public and businesses that often face challenges accessing funds.

SPACs are a popular way for companies to go public while avoiding the difficulties of a traditional IPO and ICOs, and without the strong market presence that direct listings require. They are faster and more convenient than IPOs and ICOs in that they allow projects and companies to get assurances from investors early on at an agreed-upon price, rather than the night before like traditional IPOs. Essentially, being acquired by a SPAC will offer business owners a faster IPO process under the guidance of an experienced partner.

What Causes Congestion and High Fees on EVM Blockchains?

This single-threaded limitation is a huge contributor to congestion and high fees on EVM chains.

When transaction volume surges, EVM can't scale up. Everything must be processed sequentially by that single core. The backlog accumulates, and users fiercely bid up gas fees trying to cut in line.

However, SVM and its parallel architecture can utilize more cores to efficiently manage spikes in traffic. The extra throughput prevents congestion and keeps fees low.

SVM’s Localized Fee Markets vs EVM’s Global Fee Market

Alright, last technical comparison - transaction fees.

EVM employs one global fee market across the entire network. With only one lane, activity in one dApp can jam up an unrelated dApp.

But SVM supports localized fees for each transaction. So, an NFT trade won't affect prices for a DeFi swap.
This keeps network access fair and traffic moving smoothly. Plus, dApps can subsidize fees for their users if desired.

What Emerging SVM Rollup Solutions Are Expanding the Reach of SVM?

Let's shift gears and discuss SVM adoption.

Lately, developers started building rollup solutions using SVM. Rollups bundle transactions off-chain before settling on Layer 1s like Ethereum. These allow developers to deploy SVM contracts on other chains while retaining Solana-level speeds.

1. By now you may be thinking - isn't this virtual machine concept similar to Ethereum's EVM? Perceptive observation! #SVM and EVMs serve comparable purposes, but there are some key distinctions.

2. The major one? Parallel processing capabilities. #EVM employs a sequential design that can only process one transaction at a time. But as discussed earlier, SVM leverages Sealevel to enable simultaneous execution.

3. This means #Solana can deliver vastly higher transaction volumes without getting congested. We're talking thousands of transactions per second!
