Yahoo: Massive Breaches as 1Bn Accounts Are Hacked

It is not just raining for Yahoo, but pouring as the company said Wednesday that it was hit by yet another hacking attack.

This time, the hacking activity affects more than 1 billion user accounts, doubling the number affected by a hack revealed in September.

The hack occurred in August 2013. Stolen data included users’ names, email addresses, telephone numbers, dates of birth, and encrypted passwords.

Those passwords are scrambled up with an encryption tool called MD5, which experts say is possible to crack with some patience. The data also included some security questions and answers, some of which weren’t encrypted.

“Yahoo is notifying potentially affected users and has taken steps to secure their accounts, including requiring users to change their passwords,” the company said in a statement. “Yahoo has also invalidated unencrypted security questions and answers so that they cannot be used to access an account.”

Among the victims are more than 150,000 US government and military employees, presenting a threat to national security, according to a Bloomberg report. The accounts belong to current and former White House staff, congressmen and their aides, FBI agents, officials at the National Security Agency, the Central Intelligence Agency, the Office of the Director of National Intelligence, and each branch of the US military.

The breach is another black eye for Chief Executive Marissa Mayer, who joined Yahoo in 2012 amid great fanfare. The former Google executive was charged with turning Yahoo around and tried to bring the lumbering company into the smartphone era. She made big bets on mobile, refreshing all of the company’s mobile apps, but Yahoo hasn’t been able to make much money off her projects.

The announcement caps off a rough few months for the troubled tech giant and leaves another blemish on a company seeking to sell itself to Verizon. When Yahoo announced a separate data breach in September, in which hackers in 2014 swiped user information from half a billion accounts, it was said to be the biggest cybersecurity breach ever.

Two weeks later, the company again came under fire after a report said Yahoo built tools to surveil customers’ emails for US intelligence officials.

All the while, Yahoo has been awaiting its fate with Verizon, which agreed to buy the company for $4.8 billion in July. The deal is set to close in the first quarter of next year, but Yahoo’s disclosure of the previous hack had given Verizon executives pause about the deal.

“We are confident in Yahoo’s value and we continue to work toward integration with Verizon,” a Yahoo spokeswoman said Wednesday.

Verizon issued a statement that didn’t say whether the news of the hack would have an impact on the acquisition. “As we’ve said all along, we will evaluate the situation as Yahoo continues its investigation,” Verizon’s statement read. “We will review the impact of this new development before reaching any final conclusions.”

Sumit Argawal, co-founder and vice president of product at cybersecurity company Shape Security, said the increasingly damaging hacks that Yahoo has announced fit a clear pattern in companies that don’t have their security locked down. Often, he said, companies and organizations start by describing their cybersecurity woes in small terms but keep adding new casualties to the list.

“When entities have mediocre security hygiene, they inevitably end up having lost the keys to a much larger kingdom than we originally thought,” Argawal said.

The personal information hackers stole could be used in combination with other hacked data, he added. If a criminal already has a credit card number, he might be able to use the stolen Yahoo data to find the answers to security questions that go along with it, for example.

Yahoo said in its statement that it believes the hacking may be related to the same state-sponsored hacking group it suspects is responsible for the 2014 hack. To Dmitri Sirota, CEO of data protection company BigID, that’s a sign that high profile individuals with Yahoo accounts might have been the real target of the hack.

“The reality is within that billion users, there’s probably a couple politicians, a few celebrities, a few people in key industries,” Sirota told CNET.

Financial Sector Faced AI, Blockchain and Organised Crime Threats in 2025 – Report

Published

on

Kindly share this post

The 2025 Kaspersky Security Bulletin provides a review of the major cybersecurity trends of the year and offers a look towards the future of cybersecurity, including within the financial sector.

According to the report, in 2025, the financial sector navigated a rapidly evolving cyber landscape, with malware spreading through messaging apps, AI-assisted attacks, supply chain compromises, and NFC-based fraud.

Based on Kaspersky Security Network statistics for the year (from November 2024 to October 2025), 8.15% of users in the finance sector globally faced online threats and 15.81% faced local (on-device) threats. 1,338,357 banking trojan attacks were detected by the company’s solutions. 12.8% of B2B finance sector companies faced ransomware this year – that marks a 35.7% increase in unique users in 2025 compared to the same period of 2024.

The company’s experts highlight the following cybersecurity trends and cases shaping the financial sector in 2025:

Large-scale supply chain attacks: the financial sector faced a series of unprecedented supply chain attacks, which are incidents that exploit vulnerabilities in third-party providers to reach their primary targets. The breaches demonstrated how vulnerabilities in third-party providers can cascade through national payment networks, affecting even central systems.

Organised crime converging with cybercrime: organised crime is increasingly combining physical and digital methods, creating more sophisticated and coordinated attacks. Financial institutions faced threats that blend social engineering, insider manipulation, and technical exploitation.

Old malware, new channels: cybercriminals increasingly exploit popular messaging apps to spread malware, shifting from email phishing to social channels. Banking trojans are being rewritten to use messaging platforms as a new distribution vector, enabling large-scale infections.

AI scales malware to new heights: this year, AI-enabled malware has increasingly incorporated automated propagation and evasion techniques, allowing attacks to spread faster and reach a larger number of targets. This automation also shortens the time between malware creation and deployment.

Mobile banking attacks and NFC fraud: Android malware using ATS (Automated Transfer System) techniques automate fraudulent transactions, altering transfer amounts and recipients in real time without the user noticing. NFC-based attacks have also emerged as a key trend, enabling both physical fraud in crowded places and remote fraud via social engineering and fake apps mimicking trusted banks.

Blockchain-Based C2 Infrastructure is on the rise: crimeware attackers increasingly embed malware commands in blockchain smart contracts, targeting Web3 to steal cryptocurrencies.

This method ensures persistence and makes the infrastructure extremely difficult to remove. Using blockchain for C2 operations allows attackers to maintain control even if conventional servers are shut down, highlighting a new level of resilience in cyberattacks.

Ransomware presence: these types of attacks remained a persistent threat for the financial sector with 12.8% of B2B finance organisations globally affected in November 2024 through October 2025. The figure for Africa is similar, with 12.9% of B2B finance organisations affected by ransomware from November 2024 through October 2025.

Disappearance of certain malware families: some malware families are likely to disappear, as their activity depends directly on the operations of specific criminal groups.

“In 2025, financial cyber threats evolved into a complex landscape, with attacks hitting businesses and end users alike. Criminal groups increasingly combined digital tools, insider access, AI and blockchain to scale operations, forcing organisations to secure not only their systems but also the human networks that support them,” said Fabio Assolini, Head of the Americas & Europe units at Kaspersky GReAT.

Kaspersky’s predictions for what finance cybersecurity might face in 2026, include:

Banking Trojans will be rewritten for WhatsApp distribution: criminal groups will increasingly rewrite and scale banking trojans distribution and abuse messaging apps like WhatsApp to target corporate and government organisations that still rely on desktop-based online banking. These environments are where Windows-based banking trojans thrive.

Growth of deepfake/AI services for social engineering: the trade in realistic deepfakes and AI-powered campaigns is expected to expand even more, fueling scams around job interviews and offers, driving underground demand for tools that fully bypass Know Your Customer (KYC) verification.

Appearance of regional info stealers: as Lumma, Redline and other stealers are still active, we expect to see the appearance of regional info stealers, targeting specific countries or regions, expanding the use of malware-as-a-service model.

More attacks on NFC payments: as a key technology used in payments, we’ll see more tools, more malware and attacks directed against NFC payments, in all types.

The advent of Agentic AI malware: agentic AI malware is characterised by its ability to dynamically alter behaviour mid-execution. Unlike conventional malware that relies on pre-defined instructions, agentic variants are designed to assess their environment, analyse their impact, and adapt their tactics on the fly.

This means that a single piece of malware could exhibit a range of behaviours, from initial infiltration to data exfiltration or system disruption, all in response to the specific defences and vulnerabilities it encounters.

Classic fraud will obtain new delivery: fraud will remain a major threat to end users, but its delivery methods will keep evolving. As new services and messaging platforms emerge, attackers will continue to adapt their tactics to the channels where their target audience is most active.

The persistence of ‘out of box’, pre-infected devices: the threat of counterfeit smart devices sold already infected with trojans (such as Triada) will continue to evolve.

These trojans often come with extensive capabilities, including the ability to steal banking credentials, and affect not only “gray” Android smartphones but also other smart devices such as TVs.

Report Reveals Half of 2025’s Compromised Passwords were Already Leaked

Published

on

Kindly share this post

Kaspersky’s latest research reveals that the majority of compromised passwords not only violate password-safety guidelines but also remain unchanged for extended periods, which drastically reduces their security.

To provide users with access to more sophisticated and modern ways to log in, Kaspersky’s Password Manager has been enhanced with Passkey technology, enabling users to securely access their accounts while enjoying seamless cross-device synchronisation.

Although passwords still remain one of the major authentication methods, they no longer top the security charts. Often crafted by users themselves, passwords are heavily influenced by human factors, which makes them potentially vulnerable. Kaspersky experts analysed major password leaks from 2023 to 2025 and identified several recurring patterns:

  • Users frequently append predictable elements like numbers, dates, and personal identifiers to their passwords. For example, 10% of passwords in datasets analysed contain a number resembling a date (from 1990 to 2025), 0.5% of all leaked passwords end with the number 2024, which is every 200th password!
  • The most commonly occurring password combination is ‘12345’, which drastically reduces cryptographic strength and shortens the time required for brute-force attacks to succeed. Among other popular password components are the word ‘love’ and users’ names, as well as countries’ names which are also often included in passwords.
  • Moreover, the majority of leaked passwords remain unchanged for years. In 2025, 54% of leaked passwords had already been part of prior data breaches, underscoring widespread reuse of outdated passwords. According to data analysis the average lifetime of the password found in these leaks is 3.5-4 years. 

What makes Passkeys more secure?

All these findings highlight the critical vulnerability of password-based authentication when protocols for creation, management, and storage are not rigorously followed. In response to the growing need for robust security, the industry is increasingly shifting its focus toward next-generation solutions like Passkeys, which offer stronger protection against evolving threats.

Passkey technology is based on cryptographic keys and biometrics and is not subjected to threats like phishing or data leaks. A passkey is created for a particular account on a particular platform and is stored directly on the user’s device or in a password manager.

New Passkey feature in Kaspersky Password Manager

When a user registers on a platform that supports Passkey, the device creates a private key and shares a public key with the service. The private key is stored directly on the device, which is good from a security point of view, but complicates authorisation from other devices.

Now Passkeys can be created and stored directly in Kaspersky Password Manager, which allows users to not only sign in to supported services with a single tap, but also access Passkeys on all their devices owing to secure synchronisation.

“From our own experience, we’ve seen how constantly juggling logins and passwords for work, study and even leisure can erode both time and security. Kaspersky Password Manager has long streamlined this process with tools like our secure password generator and auto-fill functionality – ensuring users never sacrifice safety for speed.

In addition to that, we are happy to offer to our customers a new Passkey feature – an enhanced level of accounts protection which makes authentication even simpler and, most importantly, more secure,” comments Marina Titova, Vice President for Consumer Business at Kaspersky.

Passkey functionality is now available on all platforms in the latest version of Kaspersky Password Manager. To create a passkey in Kaspersky Password Manager, first update the app to the latest version and grant it all necessary permissions. Then, open the website where you want to create the passkey and simply follow the in-app guidance to register and save it.

Africa’s Global Bank, United Bank for Africa (UBA) Plc, has once again, reaffirmed its leadership as one of the continent’s most innovative and resilient financial institutions, as the bank has, for the third time in five years, been named the African Bank of the year 2025 by the Banker.com.

UBA Wins Africa’s Bank of the Year for Third Time in Five Years

UBA

UBA also won the Best Bank of the Year awards in nine of its 20 African subsidiaries, bringing its total awards this year to ten as UBA Benin, UBA Chad, UBA Republic of Congo (Congo-Brazzaville), UBA Liberia, UBA Mali, UBA Mozambique, UBA Senegal, UBA Sierra Leone, and UBA Zambia, all came out tops as the best banks in their respective countries, underscoring the bank’s strength across West, Central and Southern Africa and highlighting the depth of its Pan-African franchise.

The Banker.com, a leading global finance news publication published by the Financial Times of London, organises the annual Bank of the Year Awards, and this year’s edition was held at a grand ceremony at the Peninsula, London, on Wednesday.

The Chief Executive Officer, UBA UK, Deji Adeyelure, received the awards on behalf of the bank, representing the Group Managing Director/CEO, Oliver Alawuba, and was accompanied by the bank’s Head Business Development, Mark Ifashe, and Head, Financial Institutions, Shilpam Jha.

The Banker’s awards are widely regarded as the most respected and rigorous in the global banking industry, celebrating institutions that demonstrate outstanding performance, innovation and strategic execution.

In its remarks on UBA’s winnings, the banker.com said, “For the third time in five years, UBA Group has won the coveted Bank of the Year award for Africa. UBA Group time after time punches above its weight against its larger African rivals. The bank this year also takes home nine separate country awards (one more than it gained for its last continental win in 2024), equivalent to around a quarter of the awards for the continent, and more than any of its continent-wide rivals.”

Continuing, it said, “Perhaps even more impressive is the fact that the awards were won across a broad geographic spread, going to lenders based in the Economic Community of West African States (Benin, Liberia, Senegal, Sierra Leone, and former member Mali), the Central African Economic and Monetary Community (Chad, Republic of Congo) and the Southern African Development Community (Mozambique, Zambia). Its award wins were particularly notable in the highly competitive categories for Benin and Mozambique.”

The Banker also highlighted UBA’s strong financial performance and commitment to future growth. In 2024, the Group recorded a 46.8 per cent increase in assets and a 6.1 per cent rise in pre-tax profits in local currency terms, while continuing to invest significantly in talent and technology. West Africa remains UBA’s heartland, with operating revenue and profit increasing by 87 per cent and 89 per cent respectively in H1 2025.

The bank’s digital and innovation leadership was equally recognised. During the year under review, and launched its Advance Top-Up buy-now-pay-later feature on the *919# USSD platform, expanding financial access for customers, while the bank’s chatbot Leo continued its strong growth trajectory, with transaction volumes rising by 29 per cent year-on-year in H1 2025. Notably, in August, Leo became the first African banking chatbot to enable cross-border payments via the Pan-African Payment and Settlement System (PAPSS).

UBA’s Group Managing Director/Chief Executive Officer, Oliver Alawuba, while reacting to the achievement, said the recognition affirms the bank’s long-term strategy and customer-first philosophy.

“This honour reflects the strength of our Pan-African network, the trust of our customers, and the dedication of our people. Winning Africa’s Bank of the Year for the third time in five years is not by chance; it is a testament to disciplined execution, innovation, and a deep understanding of the markets we serve,” Alawuba said.

“Our nine country awards across diverse regions of Africa show that UBA is not just growing, but growing with impact. We remain committed to driving financial inclusion, supporting economic development, and deploying technology that makes banking simpler, faster, and more accessible to Africans everywhere,” he added.

United Bank for Africa is one of the largest employers in the financial sector on the African continent, with 25,000 employees group-wide and serving over 45 million customers globally. Operating in twenty African countries, the United Kingdom, the United States of America, France and the United Arab Emirates, UBA provides retail, commercial and institutional banking services, leading financial inclusion and implementing cutting-edge technology.
