Loyalty points fraud is funding hacker holidays (Lock and Code S07E18)

Malwarebytes' Lock and Code podcast examines loyalty-points theft, with LexisNexis' Kim Sutherland explaining why stolen airline and hotel points are lucrative for fraudsters.

LexisNexis Risk Solutions' Kim Sutherland says loyalty currency is worth roughly one cent per point, making 100,000 airline points worth about $1,000 in the US. Cited incidents include a Chicago teacher who lost 240,000 airline points, discovered only via a confirmation email, and a man whose miles were used to book rental cars in New York and Memphis. The episode discusses how points theft happens and what companies and consumers can do.

Scammers leave AI fingerprints all over fake antivirus renewal page

Malwarebytes found an AI-built fake Avast renewal page in Belgium whose contractor-style code comments show scammers now generate polished pages with AI.

Malwarebytes analyzed a fake Avast Premium Security renewal page targeting Belgian users, claiming a €129.99 subscription renewal and asking for name, email, and Belgian mobile number. Harvested numbers feed callback scams where fake support agents persuade victims to install remote access software. French comments in the code, written like an AI assistant's unfinished handover, plus leftover styling and feature-free marketing copy suggest the page was generated with AI, meaning convincing localized scam pages can now be produced in minutes.

The sexy AI-powered dating app scams are here

Anthropic exposed a network of roughly 28 AI-driven dating apps using autonomous personas and gig workers to defraud paying users.

Anthropic threat intelligence uncovered a fraud network of around 28 dating apps after a prepaid account sent over 100,000 Claude API requests daily, with most chats run by autonomous AI personas and no human agent. Researchers Matthew Gore-Kormanik and Anthropic's Chris Cronbaugh documented apps including Dora, Romi, and Doni, which monetize conversations via coins; gig workers were hired only to pass liveness checks and select pregenerated replies. An operations manual written in Chinese was found inside the Doni app, and Anthropic published findings in its September 2026 AI misuse report.

Passkey-themed phishing attacks lead to Microsoft 365 data theft

Microsoft links ShinyHunters- and Helix-affiliated actors to passkey-themed vishing and device-code phishing that compromises Microsoft 365 accounts and steals cloud data.

Microsoft attributes passkey- and SSO-themed social engineering activity, observed since May 2026, to Storm-3121 (linked to ShinyHunters and Falcon) and Storm-3032 (tied to BlackFile members now operating as Helix). Attackers impersonate corporate IT help desks by phone or SMS, urging fake passkey, MFA, or SSO updates and directing victims to adversary-in-the-middle phishing pages or device-code authentication flows that yield credentials, session tokens, and OAuth tokens. Post-compromise behavior includes Microsoft Graph enumeration of users, SharePoint, and OAuth grants, plus persistence via attacker-controlled MFA methods. Google Threat Intelligence tracks related activity as UNC6671, linked to the BlackFile, Helix, Falcon, Pink, and Redact extortion gangs.

Attackers call employees’ personal phones to break into Microsoft 365 accounts

Microsoft tracks vishing campaigns by Storm-3121 and Storm-3032 that impersonate IT staff, phish Microsoft 365 credentials, and steal cloud data.

Microsoft Security Research has tracked a campaign since May 2026 in which attackers call or text employees' personal phones posing as IT staff, using passkey/MFA/SSO lures to run adversary-in-the-middle phishing or device-code authentication flows. Attackers register their own MFA methods for durable persistence, abuse Microsoft Graph for tenant discovery, and download SharePoint, OneDrive, and Exchange data below 1,000 files or emails per hour to avoid detection. Microsoft attributes initial access to actors including Storm-3121, which feeds ShinyHunters and Falcon extortion operations, and Storm-3032, the Helix extortion operation descended from BlackFile.

Safe word: What is it and why do you need one?

ESET recommends pre-agreed family safe words to counter AI voice-clone scams such as virtual kidnapping, as one-in-four Americans report receiving deepfake calls.

ESET outlines how scammers use just seconds of audio scraped from social media or work content to create convincing voice clones, with a Hiya report finding one-in-four Americans received a deepfake voice call in the past 12 months. Common schemes include virtual kidnapping calls mixing cloned voices with sobbing and background noise. A pre-agreed, non-OSINT-discoverable safe word, plus callback verification via known numbers and 2FA, reduces success rates of these frauds.

Five Venezuelan Nationals Plead Guilty in Kansas ATM Jackpotting Attempt

Five Venezuelan nationals pleaded guilty to failed ATM jackpotting attempts in Kansas as the FBI reports 700+ US incidents in 2025.

The five defendants traveled from Indiana to Kansas in December 2025 and tried to install malware on ATMs in Wamego and Manhattan, planning to remotely trigger the machines to dispense cash. Both attempts failed — one triggered an alarm — and the men were arrested days later after surveillance captured the thefts. All five pleaded guilty to conspiracy to commit bank larceny; one has received a nine-month prison sentence. The FBI counted more than 700 jackpotting incidents in 2025 with over $20 million in losses, part of 1,900 incidents since 2020.

Search results are sending people to fake Bitrefill checkouts

Scam sites impersonating Bitrefill's crypto checkout appear in search results, tricking victims into sending up to $1,990 in crypto directly to scammers.

Malwarebytes documents a cluster of lookalike domains copying Bitrefill's gift card checkout, surfaced via search engine results rather than email. Victims choose an amount up to $1,990 and pay in Bitcoin, Ethereum, USDC, USDT, Solana, or Litecoin to scammer-controlled addresses, with no recourse since crypto payments are irreversible. Domains use typosquatting and Punycode/IDN homoglyph tricks, and the fake sites run commercial analytics software to measure and optimize victim conversion. Bitrefill's security team is working with takedown specialists to remove the sites.

Cybercriminals are building phishing pages that exist only inside victims’ browsers

Barracuda details a DocuSign-themed phishing campaign that renders login pages locally via blob URLs, abusing genuine Microsoft OAuth and Teams infrastructure.

Barracuda researchers describe a phishing campaign that starts with DocuSign-themed emails carrying calendar invites pointing to genuine Microsoft OAuth endpoints, then routes victims through Microsoft Teams to a resource hosted on cdn.bloom[.]io. The login page is assembled entirely inside the victim's browser from a blob URL, registers a service worker, and runs inside a sandboxed iframe that receives live instructions from the attacker's backend. Hidden command-and-control configuration indicates the page is part of a centrally managed phishing platform that can be updated and steered across many victims. Barracuda recommends phishing-resistant MFA such as FIDO2 keys or passkeys, monitoring of OAuth flows and redirect chains, and behavior-based identity controls rather than URL blocklisting.

Once popular for attacking AI, ASCII smuggling is embraced by spammers

Spammers adopt ASCII smuggling—invisible Unicode tag characters—to evade email filters, with Microsoft Defender detections spiking to 2.5 million per day.

ASCII smuggling hides text in Unicode tag characters (e.g., U+E0041 for "A") that are invisible to humans but readable by LLMs and text processors. The technique gained attention as a stealthy prompt-injection vector and is now used by spammers to obfuscate keywords from email detectors. Microsoft reported Defender for Office smuggling detections jumped from roughly 21,000 per day to over 1.3 million in early February, reaching 2.5 million within four days, before falling sharply in mid-May.

Phishing Campaign Sends Millions of Emails Using Invisible Unicode to Evade Filters

Microsoft warns of a high-volume phishing campaign using invisible Unicode characters to split keywords like 'funding' and evade filters, peaking at 2.37 million daily messages.

Microsoft's Security Research team documented a high-volume phishing operation inserting deprecated Unicode Tags characters (U+E0000-U+E007F) inside financial keywords such as 'funding' so literal-string and regex email filters stop matching them. The campaign ran on a weekly cadence with 1-2.37 million weekday messages between February and May 15, 2026, peaking on February 26, 2026. It used hundreds of disposable finance-themed sender domains and relayed mail through ActiveCampaign's click-tracking infrastructure (acemlnd[.]com, activehosted[.]com), lending legitimate platform reputation. Microsoft ties the activity to an AI-assisted SBA loan phishing campaign that Fortra's FIRE team disclosed in September 2025.

Fraudsters steal $6 million from Tectonic crypto platform after inflating token price

Attackers inflated Tectonic's Tonic token price 100x in 20 minutes and borrowed $74 million against it, stealing $6 million before Cronos halted activity.

Attackers manipulated the price of Tectonic's thinly traded Tonic token, raising it more than 100-fold in 20 minutes, then used the inflated tokens as collateral to borrow assets in an attempted $74 million theft. About $6 million left the platform; Cronos halted blockchain activity and later restored roughly $69 million in frozen funds via an on-chain rollback. Tectonic plans a phased reopening and a postmortem. TRM Labs says market manipulation now accounts for one in eight crypto hacks, with 32 incidents in 2026, and compares the case to the 2022 Mango Markets manipulation that led to a criminal conviction.

The Money Mule Solution: What Every Scam Has in Common

CYBERA's money mule intelligence, now in Recorded Future's Payment Fraud Intelligence, targets the shared exit point of $450B-$1T annual scam losses.

Scams, especially authorized push payment fraud, do not require a breach; Global Anti-Scam Alliance estimated ~$450B in 2025 losses while CYBERA co-founder Claudio Staub puts the real figure near $1 trillion when underreporting is counted. Every scam needs a mule account to receive funds, so CYBERA uses agentic personas to engage active scammers and extract verified mule account details before payments occur, now available as an add-on to Recorded Future's Payment Fraud Intelligence. CYBERA collected over 16,000 confirmed mule accounts across 72 countries in H2 2025, finding 28% remained active 30 days or more after identification, including one account in 25 engagements. In Europe 51% of mule accounts sat at neobanks and fintechs, while outside Europe 69% were at major banks; regulatory pressure like the UK's APP reimbursement mandate is raising the stakes for institutions.
