What Is Phishing?

Phishing remains one of the most widespread and damaging cyber threats facing organizations today. Attackers craft deceptive messages designed to trick users into revealing credentials, financial information, or installing malware. To make matters worse, the tactics continue to evolve. Originating in the mid‑1990s, phishing has grown into a sophisticated weapon. Modern attackers now use AI, social media intelligence, and high‑quality impersonation techniques to create convincing campaigns that are harder than ever to detect.

Warning: A LinkedIn Phishing Campaign is Targeting Executives

A phishing campaign is abusing LinkedIn private messages to target executives and IT workers, according to researchers at ReliaQuest. The messages attempt to trick victims into opening an archive file, which will install a legitimate pentesting tool. “A critical element of this attack was the use of a legitimate, open-source Python script designed for pen-testing,” ReliaQuest says.

Warning: "Fancy" QR Codes Are Making Quishing More Dangerous

Scammers are increasingly using visually stylized QR codes to deliver phishing links, Help Net Security reports. QR code phishing (quishing) is already more difficult to detect, since these codes deliver links without a visible URL. Attackers are now using QR codes with colors, shapes, and logos woven into the code’s pattern. “Fancy QR codes further complicate detection,” Help Net Security says. “Their layouts no longer resemble the familiar black and white grid.

New Phishing Campaign Spreads Via LinkedIn Comments

A widespread phishing campaign is targeting LinkedIn users by posting comments on users’ posts, BleepingComputer reports. Threat actors are using bots to post the comments, which impersonate LinkedIn itself and inform the user that their account has been restricted due to policy violations. The comments contain links to supposedly allow the user to appeal the restriction.

1Password presents: Phishing prevention

AI-powered scams are making phishing attacks harder to spot than ever. In this demo, see how 1Password’s phishing prevention feature helps stop users before they share credentials with fraudulent websites. When a site’s URL doesn’t match a saved login, 1Password won’t autofill. Now, when a user tries to paste their credentials anyway, a warning prompts them to pause and take a closer look. This added layer of protection acts as a second pair of eyes at the moment it matters most.

Uncovering A Mass VPN Phishing Campaign - The 443 Podcast - Episode 355

This week on the podcast, we cover some first-hand research from the WatchGuard Threat Lab on a phishing campaign targeting users of nearly every major VPN vendor. After that, we discuss two recently resolved vulnerabilities in the Fortinet FortiSIEM application, then end with research from Varonis on a new attack flow against Copilot called RePrompt.

Threat Actors Exploit Misconfigurations to Spoof Internal Emails

Attackers are increasingly abusing network misconfigurations to send spoofed phishing emails, according to researchers at Microsoft. This technique isn’t new, but Microsoft has observed a surge in these attacks since May 2025. “Phishing actors are exploiting complex routing scenarios and misconfigured spoof protections to effectively spoof organizations’ domains and deliver phishing emails that appear, superficially, to have been sent internally,” the researchers write.

Phishing Campaign Abuses Google's Infrastructure to Bypass Defenses

Researchers at RavenMail warn that a major phishing campaign targeted more than 3,000 organizations last month, primarily in the manufacturing industry. The phishing messages posed as legitimate business notifications, such as file access requests or voicemail alerts, and were designed to send users to credential-harvesting login pages. Notably, the campaign abused legitimate Google infrastructure and links to avoid being flagged by security tools.
