IPA Reports Record High Fake Warning Scam Consultations in Q2 2026

The Information Processing Promotion Agency (IPA) has reported that personal security consultations received through its Information Security Relief Consultation Window reached 3,832 cases in the second quarter of 2026. This represents an approximate 8.5 percent increase compared to the 3,533 cases recorded in the previous quarter, continuing an upward trend that began in the third quarter of 2025.

Among the consultation topics, fake warning incidents stood out with a significant rise. These scams involve fraudulent pop-up screens claiming to detect malware on a user's device, designed to create panic and prompt victims to call supposed support numbers. In Q2 2026, such consultations totaled 1,428 cases, up 23.7 percent from 1,154 in the prior quarter and marking the highest volume in the last two years.

Victims of these fake warning schemes face risks of financial extortion or device infection when they engage with the criminals posing as technical support staff. Although consultations temporarily declined following arrests in a major support fraud case in May 2025, the numbers have rebounded and now exceed the 1,084 cases seen in the first quarter of 2025, before those arrests occurred.

Separately, phishing consultations increased modestly to 146 cases, a 5.0 percent rise from 139 in the previous quarter. Various tactics were observed, including schemes impersonating the National Tax Agency and other trusted organizations to steal personal or financial information.

The IPA continues to emphasize the importance of remaining alert to these evolving social engineering threats, as the upward trend in fake warning reports shows no signs of abating after three consecutive quarters of growth.

Scammers Impersonate Social Fund to Threaten Child Benefit Cancellation and Steal Savings

Fraudsters have launched a new social engineering campaign targeting parents by impersonating officials from Russia's Social Fund. Callers claim that suspicious transfers have been detected on family accounts and threaten the cancellation of child benefits unless savings are moved to a special transit account. The scheme relies on fabricated rules about income assessment and uses the promise of an 'unreported' account to trick victims into sending money. The Narodny Front's Moshelovka platform, cited by RIA Novosti, confirms that the Social Fund never requests transfers to third-party accounts for benefit verification. Families are instructed to check official notifications exclusively through Gosuslugi or by visiting an SFR office in person. Authentication codes from government services or banking apps must never be shared over the phone.

Silent Call Answering on Android: Defeating Phone Spam by Removing Human Attention

A detailed proposal suggests abandoning traditional spam call blocking in favor of allowing all incoming calls to connect automatically while keeping them invisible to the user. The approach uses Android's Telecom Framework and InCallService to answer calls silently without ringing, notifications, or screen activation. This breaks the economic model of mass dialing systems by inflating answered call metrics with empty connections that contain no human. The concept separates the technical establishment of a call from delivering user attention, forcing spammers to detect real people after the connection is made. Implementation requires the app to hold the ROLE_DIALER role and selectively invoke Call.answer() based on custom rules instead of always showing the incoming call UI. The author argues this shifts the detection burden onto robocall platforms and reduces the value of every successful connection.

Telegram Scam Bot Exposed by Fixed Timer and Deleted Messages in Telethon Userbot Analysis

A detailed investigation into a romance scam attempt on Telegram revealed an AI-driven userbot masquerading as a woman named Maria from Yaroslavl. The bot maintained consistent 4-5 minute response delays regardless of message length or time of day, responded to deleted messages, and accumulated multiple inputs before replying in batches. It refused out-of-character requests using repetitive phrases like "I am not a..." and handed off media or confusing inputs to a human operator. The bot failed to react to a nonexistent city name and ignored voice messages containing silence, leading to delayed human intervention. The chat was later deleted from the scammer side after testing, and the account ignored messages from a second profile. The analysis includes a full reconstruction of the bot's logic using the Telethon library, highlighting prompt protections against jailbreaks and reliance on fixed delays.

CACTER Upgrades PhishSim Anti-Phishing Simulation System to Reduce Employee Click Rates

CACTER has released an updated version of its PhishSim anti-phishing training platform that allows organizations to run realistic simulated attacks in just four steps. The system replicates common phishing vectors including malicious links, infected attachments, and disguised QR codes while spoofing sender addresses and official domains. Organizations can draw from a continuously refreshed template library covering invoices, financial subsidies, system notifications, and industry-specific scenarios. After each campaign the platform produces detailed visual reports that rank departments, classify employee risk levels, and recommend concrete remediation steps. Long-term use of the platform has been shown to lower average click rates from 23.88 percent to 4.16 percent. The solution is designed for immediate deployment without requiring dedicated security staff.
