By Duncan Lennox, VP & GM of Ads Privacy and Safety

Billions of people around the world rely on Google products to provide relevant and trustworthy information, including ads. That’s why we have thousands of people working around the clock to safeguard the digital advertising ecosystem. Today, we are releasing our annual Ads Safety Report to share the progress we’ve made in enforcing our advertiser and publisher policies and to hold ourselves accountable in our work of maintaining a healthy ad-supported internet.

The key trend in 2023 was the impact of generative AI. This new technology introduced significant and exciting changes to the digital advertising industry, from performance optimization to image editing. Of course, generative AI also presents new challenges. We take these challenges seriously and will outline the work we are doing to address them head-on.

Just as importantly, generative AI presents a unique opportunity to improve our enforcement efforts significantly. Our teams are embracing this transformative technology, specifically Large Language Models (LLMs), so that we can better keep people safe online.

Gen AI Bolsters Enforcement 

Our safety teams have long used AI-driven machine learning systems to enforce our policies at scale. It’s how, for years, we’ve been able to detect and block billions of bad ads before a person ever sees them. But, while still highly sophisticated, these machine learning models have historically needed to be trained extensively – they often rely on hundreds of thousands, if not millions of examples of violative content.

LLMs, on the other hand, are able to rapidly review and interpret content at a high volume, while also capturing important nuances within that content. These advanced reasoning capabilities have already resulted in larger-scale and more precise enforcement decisions on some of our more complex policies. Take, for example, our policy against Unreliable Financial Claims which includes ads promoting get-rich-quick schemes. The bad actors behind these types of ads have grown more sophisticated. They  adjust their tactics and tailor ads around new financial services or products, such as investment advice or digital currencies, to scam users.

To be sure, traditional machine learning models are trained to detect these policy violations. Yet, the fast-paced and ever-changing nature of financial trends make it, at times, harder to differentiate between legitimate and fake services and quickly scale our automated enforcement systems to combat scams. LLMs are more capable of quickly recognizing new trends in financial services, identifying the patterns of bad actors who are abusing those trends and distinguishing a legitimate business from a get-rich-quick scam. This has helped our teams become even more nimble in confronting emerging threats of all kinds.

We’ve only just begun to leverage the power of LLMs for ads safety. Gemini, launched publicly last year, is Google’s most capable AI modeI. We’re excited to have started bringing its sophisticated reasoning capabilities into our ads safety and enforcement efforts.

Our Work to Prevent Fraud and Scams

In 2023, scams and fraud across all online platforms were on the rise. Bad actors are constantly evolving their tactics to manipulate digital advertising in order to scam people and legitimate businesses alike. To counter these ever-shifting threats, we quickly updated policies, deployed rapid-response enforcement teams and sharpened our detection techniques.

  • In November, we launched our Limited Ads Serving policy, which is designed to protect users by limiting the reach of advertisers with whom we are less familiar. Under this policy, we’ve implemented a “get-to-know-you” period for advertisers who don’t yet have an established track record of good behavior, during which impressions for their ads might be limited in certain circumstances–for example, when there is an unclear relationship between the advertiser and a brand they are referencing. Ultimately, Limited Ads Serving, which is still in its early stages, will help ensure well-intentioned advertisers are able to build up trust with users, while limiting the reach of bad actors and reducing the risk of scams and misleading ads.

  • A critical part of protecting people from online harm hinges on our ability to respond to new abuse trends quickly. Toward the end of 2023 and into 2024, we faced a targeted campaign of ads featuring the likeness of public figures to scam users, often through the use of deepfakes. When we detected this threat, we created a dedicated team to respond immediately. We pinpointed patterns in the bad actors’ behavior, trained our automated enforcement models to detect similar ads and began removing them at scale. We also updated our misrepresentation policy to better enable us to rapidly suspend the accounts of bad actors.

Overall, we blocked or removed 206.5 million advertisements for violating our misrepresentation policy, which includes many scam tactics and 273.4 million advertisements for violating our financial services policy. We also blocked or removed over 1 billion advertisements for violating our policy against abusing the ad network, which includes promoting malware.

The fight against scam ads is an ongoing effort, as we see bad actors operating with more sophistication, at a greater scale, using new tactics such as deepfakes to deceive people. We’ll continue to dedicate extensive resources, making significant investments in detection technology and partnering with organizations like the Global Anti-Scam Alliance and Stop Scams UK to facilitate information sharing and protect consumers worldwide.

Investing in Election Integrity

Political ads are an important part of democratic elections. Candidates and parties use ads to raise awareness, share information and engage potential voters. In a year with several major elections around the world, we want to make sure voters continue to trust the election ads they may see on our platforms. That’s why we have long-standing identity verification and transparency requirements for election advertisers, as well as restrictions on how these advertisers can target their election ads. All election ads must also include a “paid for by” disclosure and are compiled in our publicly available transparency report. In 2023, we verified more than 5,000 new election advertisers and removed more than 7.3M election ads that came from advertisers who did not complete verification.

Last year, we were the first tech company to launch a new disclosure requirement for election ads containing synthetic content. As more advertisers leverage the power and opportunity of AI, we want to make sure we continue to provide people with the greater transparency and the information they need to make informed decisions.

Additionally, we’ve continued to enforce our policies against ads that promote demonstrably false election claims that could undermine trust or participation in democratic processes.

Overall 2023 Numbers

Our goal is to catch bad ads and suspend fraudulent accounts before they make it onto our platforms or remove them immediately once detected. AI is improving our enforcement on all these fronts. In 2023, we blocked or removed over 5.5 billion ads, slightly up from the prior year, and 12.7 million advertiser accounts, nearly double from the previous year. Similarly, we work to protect advertisers and people by removing our ads from publisher pages and sites that violate our policies, such as sexually explicit content or dangerous products. In 2023, we blocked or restricted ads from serving on more than 2.1 billion publisher pages, up slightly from 2022. We are also getting better at tackling pervasive or egregious violations. We took broader site-level enforcement action on more than 395,000 publisher sites, up markedly from 2022.

To put the impact of AI on this work into perspective: last year more than 90% of our publisher page level enforcement started with the use of machine learning models, including our latest LLMs. Of course, any advertiser or publisher can still appeal an enforcement action if they think we got it wrong. Our teams will review it and, in the cases where we find errors, use it to improve our systems.

Staying Nimble and Looking Ahead

When it comes to ads safety, a lot can change over the course of a year: the introduction of new technology such as generative AI to novel abuse trends and global conflicts. And the digital advertising space has to be nimble and ready to react. That’s why we are continuously developing new policies, strengthening our enforcement systems, deepening cross-industry collaboration and offering more control to people, publishers and advertisers.

In 2023, for example, we launched the Ads Transparency Center, a searchable hub of all ads from verified advertisers, which helps people quickly and easily learn more about the ads they see on Search, YouTube and Display. We also updated our suitability controls to make it simpler and quicker for advertisers to exclude topics that they wish to avoid across YouTube and Display inventory. Overall, we made 31 updates to our Ads and Publisher policies.

Though we don’t yet know what the rest of 2024 has in store for us, we are confident that our investments in policy, detection and enforcement will prepare us for any challenges ahead.

Kindly share this post

The Federal Ministry of Livestock Development has announced its commitment to collaborate with the World Bank Group and the African Development Bank (AfDB) to address climate change challenges affecting Nigeria’s livestock sector.

Permanent Secretary of the ministry, Dr. Chinyere-Ijeoma Akujobi, made this known during a meeting with a delegation from the two banks on Wednesday in Abuja.

She said the partnership aims to unlock opportunities for sustainable growth and resilience in the industry and that the collaboration is strategic in realising the ministry’s strategic goals.

“The proposed collaboration aligns with our mandate to mitigate the adverse impacts of climate change on livestock production, safeguard livelihoods, and promote environmentally responsible practices throughout the value chain,” the permanent secretary said.

Represented by the Director of Planning, Research and Statistics in the ministry Mr. Ohaeri Ezenwa, Dr. Akujobi highlighted the livestock sector’s significance to Nigeria’s economy.

She pointed out that “Despite its importance, the sector is highly vulnerable to climate variability and change,” outlining its implications for animal health, productivity, and greenhouse gas emissions.

While emphasising the urgency of robust policies and reliable data to address the impacts of climate change, the Director (Technical) and Team Lead of the Technical Working Group on Climate Change, Dr. Alike Peter, explained that “These realities underscore the need for evidence-based policies and coordinated national action to drive climate-smart livestock development.”

Dr. Peter said that the Technical Working Group supports the National Livestock Growth Acceleration Strategy (NLGAS), which aims to double the sector’s contribution to GDP from approximately $32 billion to $74 billion in a decade.

He added, “Both growth pathways have direct implications for greenhouse gas emissions, making climate considerations crucial in livestock development planning.”

The ministry is also collaborating with the World Bank to establish a national methane baseline and develop evidence-based mitigation measures.

Dr. Peter said, “Ongoing collaborations aim to strengthen Nigeria’s Nationally Determined Contributions (NDCs) and access carbon markets.”

Dr. Harrison Charo Karisa, a representative from the World Bank Group, highlighted opportunities in climate-smart aquaculture, the blue economy, and carbon markets.

“Seaweed can serve as a nutritious livestock feed supplement rich in essential vitamins and minerals,” he noted.

Dr. Youssouf Kabore, Chief Livestock Officer at AfDB, commended the ministry’s proactive approach and assured the bank’s support in implementing effective interventions in the livestock sector.

Kaspersky Highlights Cyber Threats at a Major Event Such as the Winter Olympics Games

Published

on

Kindly share this post

The 2026 Winter Olympics will begin on February 6 in Italy, attracting the attention of fans both online and offline. Hundreds of athletes will participate, and the host cities are expected to welcome large crowds. Kaspersky experts have listed the types of threats that may emerge in the context of a major international event, regardless of its location.

The Event Audience as a Target

The Olympics attract thousands of people travelling to the host country. Offline spectators may face unpleasant surprises such as fake tickets, which scammers distribute. This could result in stolen funds from bank accounts or even compromised cryptocurrency wallet credentials instead of access to their favourite events. Meanwhile, online fans are at risk from fake live streams and fraudulent websites selling merchandise of their favourite athletes.

Travellers may also encounter fraudulent services posing as cell phone plans that collect and steal personal and financial information. That is why it’s convenient to choose Kaspersky eSIM Store to always stay connected, avoiding potential fraudulent services and physical SIM card hassles.

Attacks on athletes

Cybercriminals may exploit publicly available information and the popularity of the participating athletes. Other scenarios might be targeted phishing attacks and deepfake-based operations aimed at data theft or blackmail.

These should be of particular concern, as well as the potential hijacking of social media accounts. In addition, athletes may face risks of ‘doxxing’, — the public exposure of private information — and other forms of tech-enabled abuse, which can impact personal safety.

Threat actors may also take advantage of vulnerabilities in online security, particularly through data leaks that affect users’ personal information. The Data Leak Checker feature in Kaspersky Premium enables users to identify potential compromises in their accounts, alerting them to any risks of exposure.

Urban infrastructure attacks

Both profit-driven and other types of threat actors may target critical city systems, including transportation, utilities, communication networks, and vulnerable public Wi‑Fi, with the aim of disrupting services or compromising operational stability.

According to a 2024 study by Kaspersky, conducted ahead of the Summer Olympic and Paralympic Games in Paris, nearly 25 percent of the approximately 25,000 free Wi-Fi hotspots analysed in the city were found to have weak or no encryption, putting users’ personal and banking data at risk of theft.

These attacks can be carried out using malware, network intrusions, or manipulation of connected systems, potentially affecting city operations and services relied upon by residents and visitors. Using security solutions such as Kaspersky Premium along with a VPN will help to protect data by encrypting Internet connection and securing online activity.

Ransomware

Ransomware actors, seeking maximum profit, may view mass events and the related entities such as vendors or other organisations in the supply chain as high-value targets. To maximise financial gain from the high demand to attend the event in person, such attacks can target hotel networks in the host city, as well as stadiums, official ticket sales platforms and other event resources.

APT attacks

Advanced Persistent Threat (APT) actors also consider large international events as strategically significant targets due to their global visibility, high concentration of critical IT infrastructure contractors and complex supply chains.

A prime example of such an attack was the Olympic Destroyer, used against the IT infrastructure at the 2018 PyeongChang Olympics. In this attack, the malware spread within the organisers’ network using compromised credentials and was aimed at sabotage and disrupting the operation of the event.

Hacktivism attacks

Hacktivist actors may launch campaigns targeting event-related organisations to achieve their strategic goals and public attention. These offensive operations could take the form of data theft and leaks, misinformation, or the disruption of the systems involved in the event, such as broadcast infrastructure or ticketing platforms, potentially affecting both the spectators and organisations.

“Events on the scale of the Olympic Games typically draw significant attention from cybercriminals, and potential threats can take many forms, affecting spectators, cities’ infrastructure and the athletes themselves, as well as millions of people accessing with digital services before, during and after the event.

The international dimension and big audience make such events especially attractive targets for sophisticated actors, who pose serious threats that everyone involved should be prepared for,” said Igor Kuznetsov, Director of Global Research & Analysis Team at Kaspersky.
