Firm Discovers Sophisticated Chrome Zero-day Exploit Used in Active Attacks

Published

Kaspersky has identified and helped patch a sophisticated zero-day vulnerability in Google Chrome (CVE-2025-2783) that allowed attackers to bypass the browser’s sandbox protection system.

The exploit, discovered by Kaspersky’s Global Research and Analysis Team (GReAT), required no user interaction beyond clicking a malicious link and demonstrated exceptional technical complexity. Kaspersky researchers have been acknowledged by Google for discovering and reporting this vulnerability.

In mid-March 2025, Kaspersky detected a wave of infections triggered when users clicked personalised phishing links delivered via email. After clicking, no additional action was needed to compromise their systems.

Once Kaspersky’s analysis confirmed that the exploit leveraged a previously unknown vulnerability in the latest version of Google Chrome, Kaspersky swiftly alerted Google’s security team. A security patch for the vulnerability was released on March 25, 2025.

Kaspersky researchers dubbed the campaign “Operation ForumTroll”, as attackers sent personalised phishing emails inviting recipients to the “Primakov Readings” forum. These lures targeted media outlets, educational institutions, and government organisations in Russia.

The malicious links were extremely short-lived to evade detection, and in most cases ultimately redirected to the legitimate website for “Primakov Readings” once the exploit was taken down.

The zero-day vulnerability in Chrome was only part of a chain that included at least two exploits: a still-unobtained remote code execution (RCE) exploit that apparently launched the attack, while the sandbox escape discovered by Kaspersky constituted the second stage. Analysis of the malware’s functionality suggests the operation was designed primarily for espionage. All evidence points to an Advanced Persistent Threat (APT) group.

“This vulnerability stands out among the dozens of zero-days we’ve discovered over the years,” said Boris Larin, principal security researcher at Kaspersky GReAT. “The exploit bypassed Chrome’s sandbox protection without performing any obviously malicious operations – it’s as if the security boundary simply didn’t exist.

The technical sophistication displayed here indicates development by highly skilled actors with substantial resources. We strongly advise all users to update their Google Chrome and any Chromium-based browser to the latest version to protect against this vulnerability.”

Google has credited Kaspersky for uncovering and reporting the issue, reflecting the company’s ongoing commitment to collaboration with the global cybersecurity community and ensuring user safety.

Kaspersky continues to investigate Operation ForumTroll. Further details, including a technical analysis of the exploits and malicious payload, will be released in a forthcoming report once Google Chrome user security is assured.

Meanwhile, all Kaspersky products detect and protect against this exploit chain and associated malware, ensuring users are shielded from the threat.

This discovery follows Kaspersky GReAT’s previous identification of another Chrome zero-day (CVE-2024-4947), which was exploited last year by the Lazarus APT group in a cryptocurrency theft campaign.

In that case, Kaspersky researchers found a type confusion bug in Google’s V8 JavaScript engine that enabled attackers to bypass security features through a fake cryptogame website.

Terra Industries, a Nigerian defence technology startup, has raised $11.75 million to expand its development of defensive systems that protect critical facilities across Africa.

The fundraising round was led by Silicon Valley venture firm 8VC, which was founded by Palantir co-founder Joe Lonsdale.

Other investors in the round include Valour Equity Partners, Lux Capital, SV Angel, and Nova Global, as well as African-focused funds Tofino Capital, Kaleo Ventures, and DFS Lab.

Terra Industries, founded in Abuja by Nathan Nwachuku and Maxwell Maduka, provides multi-domain security solutions for both air and land. Its solutions are intended to detect and respond to threats including terrorism, sabotage, and armed attacks on infrastructure.

The company’s product portfolio includes surveillance drones, ground-based robotic systems, and fixed monitoring towers deployed around sensitive locations.

Co-founder and CEO Nathan Nwachuku said the company has now fully embraced its identity as a defence-focused startup, citing the growing urgency of security challenges across Africa.

He said safeguarding critical infrastructure from terrorist threats has become unavoidable.

Nwachuku argues that protecting Africa’s infrastructure requires a different approach, one that combines local manufacturing, end-to-end system control, and software capable of independently identifying and responding to threats over large areas.

The company aims to position itself as a defence prime, similar to the role played by firms such as Anduril Industries and Palantir in the United States.

Nwachuku also disclosed that the company had earlier raised $800,000 in pre-seed funding.

With the new funding, Terra plans to increase manufacturing capacity within Africa, establish additional defence production facilities, and expand its artificial intelligence and software teams.

While software offices are planned for San Francisco and London, the company said manufacturing operations will remain on the continent.

Kaspersky Warns Telecom Threats from 2025 will Carry into 2026 as New Technology Adds New Risk

Published

Kindly share this post

Kaspersky Security Bulletin reviews what shaped telecom cybersecurity in 2025 and what is likely to persist in 2026. Advanced Persistent Threat (APT) activity, supply-chain compromise, DDoS disruption and SIM-enabled fraud continued to pressure operators in 2025, while newer technology deployments introduce additional operational risk.

In 2025, telecom operators faced four broad threat categories. Targeted intrusions (APTs) continued to focus on gaining stealthy access to operator environments for long-term espionage and leverage through privileged network positioning.

Supply chain vulnerabilities remained an entry point: telecom ecosystems rely on many vendors, contractors and tightly integrated platforms, so weaknesses in widely used software and services can provide a path into operator networks. Finally, DDoS remained a practical availability and capacity problem.

Kaspersky Security Network showed that last year, between November 2024 and October 2025, 12,79% of users in the telecommunications sector encountered web threats and 20,76% faced on-device threats. 9,86% of telecom organisations worldwide experienced ransomware.

At the same time, the telecommunications sector is moving from rapid technological development to broad implementation — and the report argues that this shift creates new opportunities and new operational risks for 2026.

Kaspersky highlights three areas where technology transitions could introduce disruption if rolled out unevenly or without strong controls: AI-assisted network management, where automation can amplify configuration errors or act on misleading data; post-quantum cryptography transitions, where rushed deployment of hybrid and post-quantum approaches could cause interoperability and performance issues across IT, management and interconnect environments; and 5G-to-satellite integration (NTN), where expanding service footprints and partner dependencies introduce new integration points and potential failure modes.

“The threats that dominated 2025 — APT campaigns, supply chain attacks, DDoS floods — aren’t going away. But now they intersect with operational risks from AI automation, quantum-ready cryptography, and satellite integration.

Telecom operators need visibility across both dimensions: maintaining strong defences against known threats while building security into these new technologies from day one. The key is continuous threat intelligence that spans from endpoint to edge to orbit,” said Leonid Bezvershenko, senior security researcher at Kaspersky Global Research & Analysis Team.

Study Reveals 88.5% of Phishing Attacks Focus on Stealing Account Credentials

Published

Kindly share this post

Kaspersky analysed phishing and scam campaigns observed from January through September 2025 and found that 88.5% of attacks globally sought credentials for various online accounts.

Another 9.5% targeted personal data such as names, addresses, and dates of birth, while 2% focused on bank card details.

According to data from Kaspersky, over 38 million phishing links were clicked in Africa in the previous year (from November 2024 to October 2025) – all of which were detected and blocked by Kaspersky solutions.

Not everyone uses protective solutions on their devices however, and phishing remains one of the most prevalent cyber threats, with attackers luring users to fake websites where they unwittingly surrender their login credentials, personal information, or bank card details.

Kaspersky research shows that most phishing pages transmit stolen information via email, Telegram bots, or attacker-controlled panels, before it enters underground resale channels.

Data stolen through phishing is rarely used only once: credentials from multiple campaigns are consolidated into data dumps and sold on dark web markets, in some cases for as little as $50. Buyers sort and verify the data to check whether accounts remain active and reusable across different services.

According to Kaspersky Digital Footprint Intelligence, average 2025 prices ranged from $0.90 for global Internet portals to $105 for crypto platforms and $350 for online banking access. Personal documents such as passports or ID cards sold for about $15 on average, with pricing influenced by account age, balance, linked payment methods, and security settings.

As datasets are enriched and combined, attackers can build detailed digital profiles that may later support targeted attacks on executives, finance staff, IT-administrators or individuals with valuable assets or personal documents.

“Our analysis shows that credentials account for nearly 90% of phishing attempts. Once collected, logins, passwords, phone numbers, and personal details are aggregated, checked, and resold, sometimes years after the initial theft.

Combined with new information, even old credentials can enable account takeovers and targeted attacks against both individuals and organisations.

By leveraging open-source intelligence and old breach data, attackers can craft highly personalised scams, turning one-time victims into long-term targets for identity theft, blackmail, or financial fraud,” said Olga Altukhova, senior web content analyst at Kaspersky.
