Here's a curious thing about people, sometimes we crave the familiar, and sometimes we demand the novel. Go see Metallica live. What do you want? Enter Sandman. Master of Puppets. The songs you know by heart. Play some deep cut from a B-side and watch 50,000 people suddenly become very interested in their phones. But go see your favourite comedian and the contract flips entirely. Tell me a joke I've heard before and I'll ask for my money back. The difference?

A large phishing campaign is using phony seasonal party invites to trick users into installing remote management and monitoring (RMM) tools, according to researchers at Symantec. “A highly active threat actor that specializes in using the ScreenConnect remote management and monitoring (RMM) software in its attacks has changed tactics and is now infecting its victims with multiple RMM tools, including LogMeIn Resolve and Naverisk,” Symantec says.

Think about your digital spaces. You’ve got your corporate email, which we all treat a bit like a high-security bank vault. We approach it with caution, we're suspicious of unfamiliar senders, and we’re primed to spot a dodgy attachment. Then, you have WhatsApp. That’s the digital equivalent of your living room. It’s comfy, familiar, and filled with people you (mostly) trust. Our guard is down.

Between 1:48pm ET on October 29 and 6:53pm ET on October 30, 2025, KnowBe4 threat analysts observed a high volume of phishing emails detected by KnowBe4 Defend that were sent from the legitimate domain of one of the world’s largest sportswear brands.

In recent weeks, the UK government has announced the introduction of its new Cyber Security and Resilience Bill. The bill aims to strengthen cyber defences for organisations that fall within the scope of critical national infrastructure (CNI), including the NHS, energy, water and transport sectors, ultimately making these industries more resilient to increasing cyber threats.

The finance and banking sector across Europe, the Middle East, and Africa (EMEA) faces extraordinary cybersecurity challenges, according to KnowBe4’s Cyber Risk in Finance and Banking Across EMEA report. While digital transformation has revolutionized operations and customer engagement, it has also created vulnerabilities that threaten the stability of the entire financial system.

A new report from Entrust warns of an increase in deepfake attacks, which now account for one in five biometric fraud attempts. Additionally, instances of deepfaked selfies have increased by 58% over the past year. “This rise in deepfakes is part of a broader trend of increasingly sophisticated attacks driven by injection attacks, which surged 40% year-over-year,” Entrust says.

Ransomware attacks spiked in October 2025, with more than 700 organizations sustaining attacks, according to a new report from Cyfirma. “In October 2025, ransomware activity surged globally, marking a significant resurgence after a period of mid-year stability,” the report says. “Victim counts climbed to 738, driven by renewed campaigns from leading operators and the emergence of several new groups.

Users and organizations should be prepared for a surge in phishing attacks over the next several weeks, as attackers take advantage of the holiday shopping season, according to a new report from Zimperium. The report notes that mobile phishing attacks increase fourfold during the holiday season. Many of these attacks impersonate well-known brands and online retailers, such as Amazon and eBay.

Using the right tool for the job is always better. Anyone who does DIY projects around the home knows how using the right tool can dramatically make the job you are doing far easier. Use the wrong tool, and that task suddenly becomes a burdensome nightmare. And after over 38 years in cybersecurity, I know that applies to cyber defense strategies, but I add one more axiom: Use the dumber, faster thing first for best results. Dumber things are usually faster at blocking a large number of things.

A new phishing kit is impersonating the Italian IT and web services provider Aruba, according to researchers at Group-IB. The kit is designed to trick users into entering their Aruba credentials, granting attackers access to sensitive accounts. “Such a target offers significant payoff: compromising a single account can expose critical business assets, from hosted websites to domain controls and email environments,” Group-IB says.

Researchers at Zimperium are tracking a new malware-as-a-service platform designed to target Android phones with banking Trojans. The platform, dubbed “Fantasy Hub,” allows unskilled threat actors to launch sophisticated malware campaigns that trick victims into granting access to their bank accounts.

Cybereason warns that the Tycoon 2FA phishing kit continues to receive upgrades, allowing unskilled cybercriminals to launch sophisticated social engineering attacks. The platform is known for its ability to bypass multi-factor authentication measures.

Researchers at Push Security warn of an extremely convincing ClickFix attack posing as a Cloudflare verification check. ClickFix is a social engineering technique that tricks the victim into copying and pasting a malicious command, then running it on their computer. In the instance observed by Push Security, the phishing page has a pop-up box that appears to be from Cloudflare, instructing the user to press the keyboard shortcuts necessary to open a terminal and run a command.

KnowBe4 Threat Labs has uncovered an emerging advanced phishing campaign targeting Microsoft 365 users globally to steal their credentials. The attackers are wielding a powerful new tool that’s completely changing the game for cybercriminals—turning what used to be complex, technical phishing setups into simple one-click launches that can bypass certain technical controls. Welcome to the era of “Quantum Route Redirect.".

Researchers at Appknox warn that malicious apps are impersonating popular AI tools like ChatGPT and DALL-E to trick users into installing malware on their mobile devices. Some of these apps simply collect user data to be sold to advertising services, while others act as full-fledged malware.

A phishing campaign is using invisible characters to evade security filters, according to Jan Kopriva at the SANS Internet Storm Center. The emails use soft hyphens to break up the subject line “Your Password is About to Expire” so the messages aren’t flagged as malicious. The email client doesn’t render the hyphens, however, so the user sees a normal sentence.

A phishing campaign is targeting LastPass users with phony notifications informing users that someone has notified the company of the user’s death and is trying to gain access to their account. The emails have the subject line, “Legacy Request Opened (URGENT IF YOU ARE NOT DECEASED).” LastPass describes the following attack flow: Notably, the attackers are also calling recipients of the emails and posing as LastPass representatives, adding another layer of legitimacy to the campaign.

I received this email the other day to my personal email account. It is a “Security Alert” from “Microsoft Helpdesk.” Oh, my! Not only is Microsoft holding five emails headed to me, but my “subscription” is expiring on the same day. The “Unsubscribe” link was just a graphic, no URL. The URL to the main button, “Review All Held Messages results” was linked to the following path (shown below): That is clearly not Microsoft or microsoft.com.

Human error remains the primary exploitation vector in mobile security incidents, according to Verizon’s latest Mobile Security Index (MSI). “At 44%, user behavior is the top cited breach contributor, just ahead of app threats, network threats, and internet threats, which were each cited by 43% of survey respondents,” the report says.

A study from Malwarebytes has found that one in three mobile users has been targeted by an extortion scam, and one in five of these users has fallen victim. Additionally, one in six users has been targeted by sextortion, with a higher number of these attacks (38%) affecting Gen Z users.

AI maturation is leading to more malicious hacking attacks. Like thousands of cybersecurity thought leaders, I’ve been speaking about AI being used maliciously since OpenAI released ChatGPT in November 2022. I’m far from alone. The entire cybersecurity industry has been warning about it nonstop. We’ve known that as AI progresses, attackers would use those same productivity features, thereby harming us.

Attackers can more easily introduce malicious data into AI models than previously thought, according to a new study from Antropic. Poisoned AI models can produce malicious outputs, leading to follow-on attacks. For example, attackers can train an AI model to provide links to phishing sites or plant backdoors in AI-generated code.
