USSD Call Forwarding Deactivation: India's Move to Safeguard Against Cyber Fraud

 


The Department of Telecommunications (DoT) has recently taken a step to tackle the surge in online fraud cases across the country. To counter various incidents of fraud resulting from illegal call forwarding, the authorities have required all telecom operators in the country to allow their USSD-based call forwarding services to be deactivated from April 15, 2024.  

In other words, USSD (Unstructured Supplementary Service Data) is a technology that makes it possible for mobile users to gain access to a wide variety of services provided by phone networks by dialling shortcodes such as *401#. Criminals impersonate customer support to trick users into dialing this code followed by their number and into being tricked by them. 

As a result, the fraudster will usually be able to receive all phone calls and forward them to him. The USSD (Unstructured Supplementary Service Data) is commonly used by users to check balances, block numbers, and other information with the option of dialling simple codes. As a result, such social engineering attacks are vulnerable to this particular system by the DoT. 

Several services can assist users with this, including call forwarding, as well as phone number rerouting. In addition to checking mobile phone balances and IMEI numbers, the service is also commonly used to check the health of mobile phones. An order has been issued as a result of an ongoing investigation into frauds involving mobile phones and online crimes that have been committed. 

In making this decision, they do so in response to a rising number of concerns about fraud, and misuse, as well as the increasing number of online scams occurring in the wake of the call forwarding feature. Once users suspend the service for their number, users will need to reactivate any call forwarding that has been set up on it. If they already have it enabled, they will have to reactivate it. 

There have been rumours, however, that users may have to use alternative methods of activating call forwarding, which has yet to be specified, to perform this functionality. The traditional ways for users to manage the forwarding of their calls will now need to be replaced by alternative ways for providers to do so. The suspension of USSD-based call forwarding services comes amid concerns about the susceptibility of such services to fraudulent activities within the telecommunications sector. 

While the request does not imply a permanent removal of the service, there are speculations that it may be reintroduced in the future with enhanced security measures to prevent misuse and fraud. Telecommunications fraud often involves cybercriminals exploiting vulnerabilities within call forwarding systems to unlawfully access sensitive information. 

One prevalent tactic utilized by fraudsters involves persuading unsuspecting users to enable call forwarding to alternative phone numbers via USSD commands. Once activated, these diverted calls serve as a conduit for intercepting confidential data, such as one-time passwords (OTPs), intended for authentication purposes. 

The USSD service, accessed by inputting specific codes on mobile keypads, offers various functionalities including prepaid balance checks and IMEI retrieval. Among these functions is the activation of unconditional call forwarding, a feature now under scrutiny due to reported instances of misuse. 

The DoT's directive to deactivate USSD-based call forwarding represents a proactive measure aimed at disrupting fraudulent schemes. By eliminating this option, telecom operators can thwart fraudsters from exploiting the feature for illicit activities. This action not only protects mobile phone users but also bolsters the integrity of the telecommunications infrastructure.

In summary, the mandated suspension of USSD-based call forwarding services marks a significant stride in combating fraudulent practices in the telecommunications realm. By depriving fraudsters of a crucial tool, the DoT's initiative contributes to the advancement of cybersecurity and fosters a safer digital landscape for both consumers and businesses.

Is Your Android Device Tracking You? Understanding its Monitoring Methods

 

In general discussions about how Android phones might collect location and personal data, the focus often falls on third-party apps rather than Google's built-in apps. This awareness has grown due to numerous apps gathering significant information about users, leading to concerns, especially when targeted ads start appearing. The worry persists about whether apps, despite OS permissions, eavesdrop on private in-person conversations, a concern even addressed by Instagram's head in a 2019 CBS News interview.

However, attention to third-party apps tends to overshadow the fact that Android and its integrated apps track users extensively. While much of this tracking aligns with user preferences, it results in a substantial accumulation of sensitive personal data on phones. Even for those trusting Google with their information, understanding the collected data and its usage remains crucial, especially considering the limited options available to opt out of this data collection.

For instance, a lesser-known feature involves Google Assistant's ability to identify a parked car and send a notification regarding its location. This functionality, primarily guesswork, varies in accuracy and isn't widely publicized by Google, reflecting how tech companies leverage personal data for results that might raise concerns about potential eavesdropping.

The ways Android phones track users were highlighted in an October 2021 Kaspersky blog post referencing a study by researchers from the University of Edinburgh and Trinity College. While seemingly innocuous, the compilation of installed apps, when coupled with other personal data, can reveal intimate details about users, such as their religion or mental health status. This fusion of app presence with location data exposes highly personal information through AI-based assumptions.

Another focal point was the extensive collection of unique identifiers by Google and OEMs, tying users to specific handsets. While standard data collection aids app troubleshooting, these unique identifiers, including Google Advertising IDs, device serial numbers, and SIM card details, can potentially associate users even after phone number changes, factory resets, or ROM installations.

The study also emphasized the potential invasiveness of data collection methods, such as Xiaomi uploading app window histories and Huawei's keyboard logging app usage. Details like call durations and keyboard activity could lead to inferences about users' activities and health, reflecting the extensive and often unnoticed data collection practices by smartphones, as highlighted by Trinity College's Prof. Doug Leith.

Maximizing Data Security: Why Simply Factory Resetting Your Android Phone Won't Suffice Before Selling

 

 
In today's tech landscape, concerns about smartphone data privacy are increasingly prevalent. While many may not possess highly sensitive information, the thought of unauthorized access to personal data remains unsettling. Despite following common safety practices online, uncertainties persist regarding the vulnerability of smartphones, particularly when selling or upgrading them.

The notion of a factory reset providing comprehensive security for Android devices is a widely accepted belief. However, questions linger about the resilience of this measure against determined hackers or even governmental entities. This isn't merely a product of paranoia but stems from a prudent approach to safeguarding personal information, a sentiment ingrained from a background in security-conscious behaviors.

The general understanding is that a factory reset renders data unrecoverable on Android devices. Yet, the reality isn't absolute. Although prevalent security measures like encryption and complex passcodes offer substantial protection, they aren't impervious to breaches. Encryption, akin to a sturdy barrier around one's home, serves as a deterrent, but persistent and resourceful attempts can circumvent it.

Modern Android phones employ file-based encryption, enhancing security by individually encrypting files using distinct keys. This method, coupled with device-specific keys and user credentials, offers robust protection. However, historical instances have shown vulnerabilities in this system, showcasing potential breaches through sophisticated means like extracting keys from a device's RAM or hacking secure enclave chips.

Recovering data post a factory reset is theoretically possible but incredibly challenging, dissuading the average user from being an easy target. Following a reset, while data recovery is possible, the encrypted nature of the files renders them unreadable, owing to the robust AES-256 encryption standard employed by Android.

Nevertheless, specialized tools such as Cellebrite, marketed to security agencies, possess additional exploits to breach phone security and extract information, including decrypting third-party data and accessing complete file systems. While this might not concern the majority, it underscores the importance of ensuring data security beyond factory resets.

Additional steps, such as using apps to securely wipe phone storage by overwriting it with nonsensical binary data, can further fortify data protection. Although a factory reset is a potent measure for the average user, employing secure wipe programs adds an extra layer of security, reassuring individuals concerned about potential data breaches.

While a factory reset does offer substantial protection for most, opting for an extra layer of security, such as employing secure wipe programs, can offer peace of mind in safeguarding personal data, especially when selling or upgrading an Android device.

Mobile Privacy Milestone: Gmail Introduces Client-Side Encryption for Android and iOS

 


Encryption is one of the most important mechanisms for protecting data exchanged between individuals, especially when the information exchange occurs over e-mail and is quite sensitive. As a result, it can be complicated for users to be able to achieve this when they use public resources such as the internet. 

Now that Gmail has added client-side encryption to its mobile platform, users may feel safer when sending emails with Gmail on their mobile devices. Earlier this year, Google announced that it would be supporting Android and iOS mobile devices with client-side encryption in Gmail too. 

Using Google's client-side encryption (CSE) feature, which gives users more control over encryption keys and data access, Gmail can now be used on Android and iOS devices, as well as web browsers. In the past few months, Gmail's web version has been upgraded to support client-side encryption. This app lets users read and write encrypted emails directly from their smartphones and tablets. 

In addition to the Education Plus and Enterprise Plus editions of Google Workspace, the Education Standard edition also offers the feature. Workspace editions that don't support client-side encryption, such as Essentials, Business Starter, Business Standard Plus, Business Pro Plus, etc., do not support client-side encryption. 

Furthermore, users who have personal Google accounts are not able to access it. For those using email via desktop through Gmail, client-side encryption will be available at the end of 2022 on a trial basis. Workspace users with a subscription to Enterprise Plus, Education Plus, or Education Standard were the only ones able to take advantage of this feature at that time. 

Client-side encryption also prevented certain features from working, including the multi-send mode, signatures, and Smart Compose, which all functioned properly when using client-side encryption. A more robust version of the feature has been added to the Google Play Store since then. 

The company added the capability to allow users to see contacts even if they are unable to exchange encrypted emails so that they can keep in touch. There is also a security alert that appears in Google Mail when users receive attachments that are suspicious or that cannot be opened because of security concerns. 

While client-side encryption will now be available under the Enterprise Plus, Education Plus, and Education Standard Workspace accounts shortly, it has remained relatively exclusive. This type of Workspace account will also be the only kind of account that will be able to take advantage of the mobile rollout of client-side encryption. 

By using the S/MIME protocol, Google said that it will allow its users to encrypt and digitally sign their emails before sending them to Google servers so that they adhere to compliance and regulatory requirements. This feature lets users access and work with your most sensitive data from anywhere with their mobile devices. 

The blue lock icon present in the subject field of Gmail for Android or iOS users allows them to enable client-side encryption while they are writing a Gmail email for Android or iOS devices. Administrators will, however, have to enable access to the feature through their CSE administration interface, as it is disabled by default. 

During the past week, the search giant celebrated its 25th anniversary by letting teens (age 13 and above) try out its generative search service. The company also announced a new tool called Google-Extended that would enable website administrators to control how Google's Bard AI can be trained on their content. It allows website administrators to control whether or not Google can access their content. 

In addition to pulling the plug on Gmail's basic HTML version, which used to support legacy browsers and users with slow connections and could be used to support legacy browsers, Google will also drop the automatic loading of Gmail's Basic view, instead loading the Standard view by default early next year. Customers who are using Google Workspace Enterprise Plus, Education Plus, and Education Standard will be able to take advantage of this feature.

Data Exfiltration malware MMRat Mobile Network Privacy Protobuf Technology threats Trojan

Rare Technique Deployed by Android Malware to Illicitly Harvest Banking Data

 

Trend Micro, a cybersecurity research firm, has recently unveiled a novel mobile Trojan that employs an innovative communication technique. This method, known as protobuf data serialization, enhances its ability to pilfer sensitive data from compromised devices.

Initially detected by Trend Micro in June 2023, this malware, named MMRat, primarily targets users in Southeast Asia. Surprisingly, when MMRat was first identified, popular antivirus scanning services like VirusTotal failed to flag it as malicious.

MMRat boasts a wide array of malicious functionalities. These include collecting network, screen, and battery data, pilfering contact lists, employing keylogging techniques, capturing real-time screen content, recording and live-streaming camera data, and even dumping screen data in text formats. Notably, MMRat possesses the ability to uninstall itself if required.

The capacity to capture real-time screen content necessitates efficient data transmission, and this is where the protobuf protocol shines. It serves as a customized protocol for data exfiltration, using distinct ports and protocols to exchange data with the Command and Control (C2) server.

Trend Micro's report highlights the uniqueness of the C&C protocol, which is customized based on Netty, a network application framework, and the aforementioned Protobuf. It incorporates well-designed message structures, utilizing an overarching structure to represent all message types and the "oneof" keyword to denote different data types.

Researchers have uncovered instances of this malware concealed within counterfeit mobile app stores, masquerading as government or dating applications. While they commend the overall sophistication of these efforts, it's essential to note that these apps still request permissions for Android's Accessibility Service, a common red flag that clearly signals their malicious nature.
