In the wake of last week’s terrorist attack in Westminster, the British government on Sunday disclosed that its security services must have access to encrypted messaging applications such as WhatsApp, revealing it was used by the killer behind the parliament attack.

In this piece, Yudala – the largest online and offline retail chain – examines the benefits of WhatsApp encryption and why access to these encrypted messages by a third-party may mean less privacy for you…

Created in 2009 as an alternative to text messaging, WhatsApp is today one of the world’s most popular instant messaging service with more than one billion users in 180 countries.

According to a May 2016 report from research firm SimilarWeb, WhatsApp is the top chat app in 109 countries, including Brazil, India, and the United Kingdom. Facebook acquired WhatsApp in 2014 to make a bigger play in the rapidly-growing messaging market, along with its own Messenger platform. At the time the deal was announced, WhatsApp had 450 million users worldwide.

Khalid Masood, the 52-year-old Briton who killed four people before being shot dead in a rampage in Westminster on Wednesday, reportedly used WhatsApp to send a message some moments before the assault – a discovery that has seen the UK government determined to gain access to the end-to-end encrypted messages sent through the app.

Home Secretary Amber Rudd affirmed that it was “completely unacceptable” that police and security services had not been able to crack the heavily encrypted service.
“You can’t have a situation where you have terrorists talking to each other — where this terrorist sent a WhatsApp message — and it can’t be accessed,” she said.

WHAT DOES WHATSAPP END-TO-END ENCRYPTION MEAN?
WhatsApp’s end-to-end encryption ensures only you and the person you’re communicating with can read what is sent and nobody in between, not even WhatsApp. Your messages are secured with a lock and, only the recipient and you, have the special key needed to unlock and read your message. For added protection, every message you send has a unique lock and key. All of this happens automatically: no need to turn on settings or set up special secret chats to secure your messages.

It is also important to note that end-to-end encryption is always activated, provided all parties are using the latest version of WhatsApp. There is no way to turn off end-to-end encryption. End-to-end encryption is available when you and the people you message are on the latest versions of WhatsApp.

The benefits of end-to-end encryption on WhatsApp are numerous and has remained one of the major factors that has contributed to the growing popularity of the Facebook-owned service. These benefits include:

Privacy: With end-to-end encryption in place, people can communicate with each other and express themselves freely without fear of unintended people gaining access to their private stuff. This way, you can talk to your doctor about your medication, hold intimate chat sessions with your spouse/partner or have a discussion with an associate about a business proposal without the fear of being overheard or the call being tapped.

Safe group chats: Group chats are also safely encrypted, thereby lending an air of confidentiality to messages sent in such a forum. With encryption featuring in group chats, non-group members will have no clue at all about the happenings in the group. This makes it more attractive for people with like minds and interests to discuss their affairs in WhatsApp groups without the fear of being overheard.

Encryption works by default: Encryption setting is turned on by default by WhatsApp in all devices. If you are running the version of WhatsApp that has encryption support, you will be informed of this on your chat screen when you send messages across along with a lock symbol next to the confirmation screen. You can also verify the default ON setting by making use of a unique QR code on the phone of each contact in your list.

In case, for some reason, the default encryption setting does not get activated, you can do it yourself through a simple process. In your chat window, just click on your contact’s name at the top of the window to display his or her profile details. You will find an option to turn the encryption on.

WhatsApp can’t read your messages: End-to-end encryption means that even if it wanted to, WhatsApp cannot gain access to your messages. In other words, only the sender and receiver can read intended messages.

Not even WhatsApp employees or hackers will be able to gain access to the messages sent or received. This applies to any form of messages – text, images, videos and files.

Encryption works on all devices: The encryption in WhatsApp works using an open-source protocol known as Signal that is developed by an organization called Open Whsiper Systems. This company has worked in close association with WhatsApp in determining its requirements and the level of encryption to be provided.

The app ensures that smartphones featuring this app support the encryption and decryption keys to be applied to messages going out and coming into the device.

The encryption technology is supported by all recent WhatsApp versions running on Android, Windows, iPhones, and Nokia phones. Keeping in line with the usual trend, WhatsApp first introduced encryption on Android before extending it to other platforms.

Even in error, you are protected: WhatsApp has become very focused on making encryption mandatory that it now refuses to work on unencrypted messages.

If a person tries to send a contact an unencrypted message, WhatsApp will immediately prevent him or her from doing so.

Additionally, the sender will be informed that this is because the messages being sent from his or her end are not encrypted.

No server hacks with end-to-end encryption: When the encryption process was first implemented by WhatsApp, it took place over a central hub.

Messages management and key exchange coordination take place centrally, apart from central control of the encrypted code that is executed on both the servers and mobile phones.

However, this did not result in complete safety and paved way for end-to-end encryption. As a result, messages will get decrypted only on the receivers’ handsets rather than in between the server and the handsets.

Oracle Sacks 12,000 in India, Begins Shift to AI

Oracle, US-based technology giant, has initiated a sweeping round of layoffs affecting thousands of employees globally, with India among the worst-hit regions, according to multiple reports.

Oracle Sacks 12,000 in India, Begins Shift to AI

The job cuts, which began on March 31, are part of a broader restructuring exercise that could impact between 20,000 and 30,000 employees worldwide, making it one of the largest workforce reductions in the company’s history.

While the exact number remains unconfirmed, multiple reports  suggest that around 12,000 employees in India have been affected,

Employees across several geographies, including India, the United States, Canada, and Mexico, reported receiving termination emails early in the morning, informing them that their roles had been eliminated with immediate effect.

“Today is your last working day,” the email stated, citing “organisational change” as the reason for the decision. Access to company systems, including email and internal platforms, was revoked shortly thereafter.

The communication, according to Business Insider, described the move as part of a broader “reduction in force and other terminations,” and said affected employees would be eligible for severance benefits subject to company policy.

The email also instructed employees to share personal contact details to receive separation documents.

In India, impacted employees have reportedly been offered severance packages that include 15 days’ salary for each completed year of service, notice period pay, leave encashment, gratuity where applicable, and an additional two-month salary top-up in cases of voluntary separation.

The layoffs are linked to Oracle’s strategic shift towards artificial intelligence (AI) and cloud infrastructure.

The company has announced plans to invest approximately USD 50 billion in AI infrastructure and has reportedly raised an equivalent amount in debt to fund its expansion.

In a recent regulatory filing, Oracle said it expects restructuring costs for fiscal 2026 to reach up to USD 2.1 billion, largely driven by severance payouts and related expenses.

The move comes as Oracle looks to strengthen its position against global cloud competitors such as Amazon and Alphabet.

Uncertainty continues to loom over employees, with reports indicating that another round of layoffs could follow in the coming weeks. Employees who were affected described the layoffs as abrupt, with little prior indication.

Some former staff members have taken to social media to share their experiences.

Tricia S Marsh, a former Senior Principal at Oracle, said the layoffs marked the end of an important chapter in her career while urging affected colleagues to remain hopeful.

As of May 2025, Oracle had around 162,000 full-time employees globally.

Cybersecurity Firm Uncovers CrystalX RAT which Steals Data, Mocks its Victims

Published

Kindly share this post

Kaspersky Global Research & Analysis Team (GReAT) has uncovered an active malicious campaign distributing a previously undocumented RAT with a very broad feature set. Beyond the standard remote access trojan functionality, it combines stealer, keylogger, clipper, and spyware capabilities.

Cybercriminals are selling it to third parties as MaaS (malware-as-a-service) promoting it on YouTube and Telegram, increasing the likelihood of its use across a wider range of actors, including less-skilled operators.

Due to its stealer functionality, the malware can collect a wide range of data about its victim: it gathers system information, extracts credentials for Steam, Discord and Telegram, and also harvests data from web browsers. It also poses a threat to cryptocurrency users, as it includes a browser-based clipper that replaces crypto wallet addresses.

Beyond data theft, CrystalX RAT is capable of full-scale surveillance, with the ability to take screenshots, record audio from the microphone, and capture video from both the webcam and the victim’s screen.

Particularly notable is the CrystalX RAT “playful” Prankware feature set, which is actively promoted by the developers. These capabilities allow operators to visibly interfere with the victim’s system by shaking the mouse cursor, setting wallpapers on the victim’s screen, changing screen orientation, hiding desktop icons, forcing system shut downs, and even delivering real-time pop-up notifications and messages to the victim.

While seemingly trivial, these features introduce a disruptive and psychological dimension to the attack, making the attack both visible and distressing for the victim.

Kaspersky reports attacks targeting users in Russia, but the trojan has the potential to spread to other countries due to its sales and distribution model.

“Such a diverse feature set effectively enables a 360-degree compromise of the victim and a complete loss of privacy. Beyond gaining access to account credentials, the stolen data could potentially be used for blackmail.

“At the moment, the initial infection vector is not precisely known, but it is already affecting dozens of victims. Our telemetry is already detecting new versions of the implants, indicating that this malware is still actively developed and maintained.

“We expect the number of victims to grow significantly and its geographic spread to expand in the near future,” says Leonid Bezvershenko, senior security researcher at Kaspersky GReAT.

Kaspersky Warns of a New Phishing Technique Leveraging Bubble, a no-code AI Platform

Published

on

Kindly share this post

Kaspersky has discovered a new phishing tactic used to evade traditional security controls that exploits Bubble, a platform that allows users to build web and mobile applications through a visual interface without writing code.

Attackers are increasingly adopting innovative tools designed for legitimate software development and repurposing them to boost phishing campaigns.

Traditional phishing attacks often rely on malicious links or obvious redirection techniques, which are typically flagged and blocked by modern security systems.

However, attackers are now leveraging Bubble’s no-code environment to generate intermediary web applications which are hosted on Bubble’s legitimate infrastructure and trusted domains such as *.bubble.io, which improves their credibility and helps them bypass security filters.

These applications function as disguised redirectors, silently forwarding victims to malicious credential-harvesting websites.

In the observed campaign, victims were ultimately redirected to a convincing imitation of a Microsoft login page, protected by a Cloudflare verification layer designed to further obscure malicious intent.

This technique is likely being integrated into broader phishing-as-a-service (PhaaS) platforms and phishing kits. These kits enable a wide range of malicious capabilities with ready-made tools, including real-time interception of session cookies, driving phishing campaigns through legitimate services such as Google Tasks and Google Forms, and carry out adversary-in-the-middle (AiTM) attacks that can bypass multi-factor authentication.

They also support the generation of phishing emails using AI, implement geo-filtering and anti-detection mechanisms to evade security crawlers and are often hosted on reputable cloud services like AWS to avoid blacklisting.

“The use of legitimate platforms like Bubble introduces a new level of trust abuse, making it harder for both users and automated systems to distinguish between safe and malicious content. This significantly increases the likelihood of credential theft, unauthorised access and potential data breaches,” comments Roman Dedenok, Anti-Spam Expert at Kaspersky.
