Ransomware attacks involving data theft have surged by 275% in 2026, according to a new report from Zscaler. Attackers exfiltrated more than 896.2 terabytes of data from victim organizations, more than seven times the amount stolen during the 2023–2024 reporting period.

Researchers at ReliaQuest have observed a surge in voice phishing (vishing) and Microsoft Teams phishing over the past several months, particularly from extortion groups like ShinyHunters. “Attackers overwhelmingly targeted users and their unmanaged devices to gain access to accounts,” the researchers write.

The digital landscape faces a new and complex challenge: the rise of generative AI. While these tools offer incredible potential for innovation, they also provide malicious actors with sophisticated ways to deceive even the most vigilant users.

A legitimate sender does not mean legitimate content. Attackers have abused legitimate services such as DocuSign, SharePoint, Adobe Sign, Dropbox and Google Drive to exploit that trust for years. KnowBe4's Phishing Threat Trends Report Vol. 7, released April 2026, flagged this shift at the industry level: 22% of all phishing attacks are now sent through a legitimate platform, with attackers moving from impersonating a brand to abusing that brand's actual infrastructure.

Somewhere in your security and compliance stack, there are records that prove your employees completed their security awareness training. But when these records need to serve as evidence, would they actually hold up to scrutiny? For many companies, the answer is no, and that’s becoming a major risk. Following steadily rising claims over the years, insurers have narrowed their coverage definitions and requiring stricter adherence to security standards.

Researchers at Fortra are tracking a new variant of calendar phishing in which threat actors trick employees into sharing meeting links internally. The attackers pose as prospective customers and contact non-sales employees, asking to be directed to a sales representative in order to discuss a business opportunity. The attacker then sends the employee a meeting link to forward to a sales contact. The attack takes place as follows.

At any given moment, there’s an employee somewhere in the world tuning out of a phishing training module that was translated from another language. Every word is rendered correctly, yet the learner still stops paying attention. In these situations, the translation often gets the blame for not engaging the learner, but the real culprit is design.

As millions of shoppers prepare their wishlists and await discounts for Amazon’s Prime Big Deal Days starting October 6, cybercriminals are gearing up for their own payday. In the weeks leading up to major shopping events, Amazon impersonation campaigns reach an annual peak.

Researchers at Netskope are tracking a phishing kit that hijacks users’ browser windows to display fake security alerts. The malicious websites are distributed via Google Ads, and pose as normal online stores. Once a user clicks a link on the page, however, the site will present them with an urgent-looking security warning.

Spies have always relied on technology, disguises, secret communications and clever gadgets, at least if the movies are to be believed. But some of the most effective tools in the espionage business have always been people. Convince the right person to open a door, reveal a secret or trust someone they should not, and suddenly bypassing the sophisticated security system becomes unnecessary.
