Introduction

Phishing is a harmful tactic in which malicious actors pretend to be trusted sources to trick people into sharing their sensitive data. In this article, we will shed light on what phishing is, how it works, and what you can do to avoid falling victim to these types of scams.

How phishing works

Phishing relies primarily on social engineering, a method in which attackers manipulate people into divulging sensitive information. Attackers collect personal data from public sources (such as social media) to create seemingly authentic emails. Victims often receive malicious messages that appear to be from family contacts or reputable organizations.

The most common form of phishing is through emails that contain malicious links or attachments. Clicking on these links can install malware on the user's device or take them to counterfeit websites designed to steal personal and financial information.

While it is easier to detect poorly written phishing emails, cybercriminals are employing advanced tools such as chatbots and AI speech generators to improve the authenticity of their attacks. This makes it difficult for users to distinguish between genuine and fraudulent communications.

How to recognize phishing attempts

Identifying phishing emails can be tricky, but there are some signs you can watch for.

Common signs

Be careful if the message contains suspicious URLs, uses public email addresses, induces fear or urgency, requests personal information, or has spelling and grammatical errors. In most cases, you should be able to hover your mouse over links to check the URLs without clicking them.

Scams based on digital payments

Phishers often impersonate trusted online payment services, such as PayPal, Venmo, or Wise. Users receive fraudulent emails urging them to verify the details of a supposed login. It is essential to remain alert and report any suspicious activity.

Phishing attacks in the area of ​​finance

Scammers pose as banks or financial institutions and claim security flaws to obtain personal information. Common tactics include misleading emails about money transfers or direct deposit scams to new employees. They may also claim that there is an urgent security update.

Work-related phishing scams

These personalized scams involve attackers posing as executives, CEOs, or CFOs, requesting fake wire transfers or purchases. Voice phishing with AI voice generators over the phone is another method used by scammers.

How to prevent phishing attacks

To avoid phishing attacks, it is important to employ multiple security measures. Avoid clicking directly on any link. Instead, head to the company's website or official communication channels to verify if the information you received is legitimate. Consider using security tools such as antivirus software, firewalls, and spam filters.

Additionally, organizations should use email authentication standards to verify incoming emails. Common examples of email authentication methods include DKIM (DomainKeys Identified Mail) and DMARC (Domain-based Message Authentication, Reporting and Conformance).

For individuals, it is essential to inform their family and friends about the risks of phishing. For businesses, it is vital to educate employees about phishing techniques and provide regular awareness training to reduce risks.

If you need more help and information, look for government initiatives like OnGuardOnline.gov and organizations like Anti-Phishing Working Group Inc. These provide more detailed resources and guidance for detecting, preventing, and reporting phishing attacks.

Tips for phishing

Phishing techniques are evolving, and cybercriminals use a variety of methods. The different types of phishing are usually classified based on the objective and attack vector. Let's analyze it in greater detail.

Cloning phishing

The attacker uses a previously sent legitimate email and copies its contents into a similar one that contains a link to a malicious site. The attacker could also claim that this is an updated or new link, and indicate that the previous one was incorrect or had expired.

Spear phishing

This type of attack focuses on a person or institution. A spear attack is more sophisticated than other types of phishing because it is tailored. This means that the attacker first collects information about the victim (for example, names of friends or family) and uses this data to lure the victim to a malicious website file.

Pharming

The attacker contaminates a DNS record, which effectively redirects visitors from a legitimate website to a fraudulent one that the attacker created beforehand. This is the most dangerous of the attacks because the DNS records are not under the user's control, making the user unable to defend themselves.

Whaling

A form of spear phishing that targets wealthy and important people, such as CEOs and government officials.

Email spoofing

Phishing emails often spoof communications from legitimate companies or people. They may include links to malicious sites created for unsuspecting victims. On those sites, attackers collect login credentials, as well as PII, using cleverly disguised login pages. The pages may contain Trojans, keyloggers and other malicious scripts that steal personal information.

Website redirects

Website redirects send users to different URLs than the ones they intended to visit. Actors who exploit the vulnerabilities can insert redirects and install malware on users' computers.

Typosquatting

Typosquatting directs traffic to spoofed websites that use foreign language spelling, common misspellings, or subtle variations in the top-level domain. Phishers use domains to imitate legitimate website interfaces, taking advantage of users who type or read the URL incorrectly.

Fake paid ads

Paid ads are another tactic used for phishing. These (fake) ads use domains that the attackers applied typosquatting to and are paid to rise in search results. The site may even appear as one of the top search results on Google.

Watering hole attack

In a watering hole attack, phishers study users and determine which websites they frequently visit. They scan these sites for vulnerabilities and attempt to inject malicious scripts designed to target users the next time they visit that website.

Identity theft and fake giveaways

They impersonate the identity of influential figures on social networks. Phishers may impersonate key company leaders and advertise giveaways or engage in other deceptive practices. Victims of this hoax can even be targeted individually through social engineering processes aimed at finding gullible users. Actors can hack verified accounts and modify usernames to impersonate a real figure while maintaining verified status.

Recently, phishers have been heavily targeting platforms like Discord, X, and Telegram for the same purposes: spoofing chats, impersonating individuals, and imitating legitimate services.

Malicious applications

Phishers can also use malicious apps that monitor your behavior or steal sensitive information. Apps can pose as price trackers, wallets, and other cryptocurrency-related tools (which have a user base predisposed to trading and owning cryptocurrencies).

SMS and voice phishing

A form of text message-based phishing, usually via SMS or voice messages, that encourages users to share personal information.

Phishing vs. Pharming

Although some consider pharming to be a type of phishing attack, it relies on a different mechanism. The main difference between phishing and pharming is that phishing requires the victim to make a mistake. In contrast, pharming only requires that the victim attempt to access a legitimate website whose DNS record was compromised by the attacker.

Phishing in the crypto and blockchain space

While blockchain technology provides strong data security due to its decentralized nature, users in the blockchain space should remain vigilant against social engineering and phishing attempts. Cybercriminals often try to exploit human vulnerabilities to gain access to private keys or login credentials. In most cases, scams are based on human error.

Scammers may also try to trick users into revealing their seed phrases or transferring funds to fake addresses. It is important to be careful and follow recommended safety practices.

Conclusions

In conclusion, understanding phishing and staying informed about evolving scam techniques is crucial to safeguarding personal and financial information. By combining strong security measures, education and awareness, individuals and organizations can strengthen themselves against the ever-present threat of phishing in our interconnected digital world. Stay SAFU!
