Apple Patches Zero-Day Flaw allowing Third-Party Access to Locked Devices

 

Tech giant Apple fixed a vulnerability that "may have been leveraged in a highly sophisticated campaign against specific targeted individuals" in its iOS and iPadOS mobile operating system updates earlier this week.

According to the company's release notes for iOS 18.3.1 and iPadOS 18.3.1, the vulnerability made it possible to disable USB Restricted Mode "on a locked device." A security feature known as USB Restricted Mode was first introduced in 2018 and prevents an iPhone or iPad from sending data via a USB connection if the device hasn't been unlocked for seven days. 

In order to make it more challenging for law enforcement or criminals employing forensic tools to access data on those devices, Apple announced a new security feature last year which triggers devices to reboot if they are not unlocked for 72 hours. 

Based on the language used in its security update, Apple suggests that the attacks were most likely carried out with physical control of a person's device, implying that whoever exploited this vulnerability had to connect to the person's Apple devices using a forensics device such as Cellebrite or Graykey, two systems that allow law enforcement to unlock and access data stored on iPhones and other devices. Bill Marczak, a senior researcher at Citizen Lab, a University of Toronto group that studies cyberattacks on civil society, uncovered the flaw.

However, it remains unclear who was responsible for exploiting this vulnerability and against whom it was used. However, there have been reported instances in the past in which law enforcement agencies employed forensic tools, which often exploit zero-day flaws in devices such as the iPhone, to unlock them and access the data inside.

Amnesty International published a report in December 2024 detailing a string of assaults by Serbian authorities in which they utilised Cellebrite to unlock the phones of journalists and activists in the nation before infecting them with malware. According to security experts, the Cellebrite forensic tools were probably used "widely" on members of civil society, Amnesty stated.

Are We Ready For The Next Major Global IT Outage? Here's All You Need to Know

 

Last Friday, a glitch in the tech firm led to a global disruption impacting cross-sector activities. Hospitals, health clinics, and banks were impacted; airlines grounded their planes; broadcasting firms were unable to broadcast (Sky News went off the air); emergency numbers such as 911 in the United States were unavailable; and MDA experienced several troubles in Israel. 

This incident had a significant impact in the United States, Australia, and Europe. Critical infrastructure and many corporate operations were brought to a halt. In Israel, citizens instantly linked the incident to warfare, namely the UAV that arrived from Yemen and exploded in Tel Aviv, presuming that Iran was attacking in the cyber dimension. 

What exactly happened? 

CrowdStrike, an American firm based in Texas that provides a cybersecurity protection system deployed in several companies across the world, announced on Friday morning that there was a glitch with the most recent version of their system given to customers. The issue caused Microsoft's operating system, Windows, not to load, resulting in a blue screen. As a result, any organisational systems that were installed and based on that operating system failed to load. In other words, the organisation had been paralysed. 

But the trouble didn't end there. During the company's repair actions, hackers "jumped on the bandwagon," impersonating as staff members and giving instructions that essentially involved installing malicious code into the company and erasing its databases. This was the second part of the incident. 

Importance of risk management 

Risk management is an organisational discipline. Within risk management processes, the organisation finds out and maps the threat and vulnerability portfolio in its activities, while also developing effective responses and controls to threats and risks. Threats can be "internal," such as an employee's human error, embezzlement, or a technical failure in a computer or server. Threats can also arise "externally" to the organisation, such as consumer or supplier fraud, a cyberattack, geopolitical threats in general, particularly war, or a pandemic, fire, or earthquake. 

It appears that the world has become far more global and technological than humans like to imagine or believe. And, certainly, a keyboard error made by one individual in one organisation can have global consequences, affecting all of our daily lives. This is the fact, and we should recognise it as soon as possible and start preparing for future incidents through systematic risk management methods.

Cyber Criminals Siphoned 'Almost All' of AT&T's Call Logs Over Six Months

 

Hackers accessed AT&T's data storage platform in April, stealing metadata from "nearly all" call records and messages sent by users over a six-month period in 2022. AT&T filed paperwork with the Securities and Exchange Commission (SEC) on Friday, stating that it learned of the incident on April 19.

The company revealed to a local media outlet that the breach took place via the third-party cloud platform Snowflake, a data storage giant plagued by hackers who have attacked some of the company's most notable clients and released stuff affecting hundreds of millions of individuals. An investigation revealed the attacker stole files from AT&T's Snowflake account between April 14 and April 25.

When asked why the attacker was still able to access the Snowflake account nearly a week after AT&T detected the issue, the spokesman stated that it "took time to investigate the claim of a breach, determine its source, isolate the impacted data, and close off the illegal access point." 

The spokesperson stated that the hackers took "aggregated metadata" regarding calls or messages, not the content of the talks. AT&T has the most wireless subscribers in the United States, far more than rivals Verizon and T-Mobile. 

According to an annual report for 2022, the incident affected around 109 million people's accounts. The telecom giant believes the hacker stole "files containing AT&T records of customer call and text interactions" from around the beginning of May 2022 to the end of October, as well as on January 2, 2023.

The hack impacted "records of calls and texts of nearly all of AT&T's wireless customers and customers of mobile virtual network operators (MVNO) using AT&T's wireless network.” 

“These records identify the telephone numbers with which an AT&T or MVNO wireless number interacted during these periods, including telephone numbers of AT&T wireline customers and customers of other carriers, counts of those interactions, and aggregate call duration for a day or month,” the company noted in the SEC filing. 

“For a subset of records, one or more cell site identification number(s) are also included. While the data does not include customer names, there are often ways, using publicly available online tools, to find the name associated with a specific telephone number.” 

AT&T pledged to tell current and former customers, and it stated it had locked down the "point of unlawful access." The company stated in the filing that at least one person was arrested in connection with the theft.

Tech Giant Apple Launches Its Own Password Manager App

 

People with knowledge of the matter claim that Apple Inc. launched a new homegrown app this week called Passwords, with the goal of making it simpler for users to log in to websites and apps. 

The company introduced the new app as part of iOS 18, iPadOS 18 and macOS 15, the next major versions of its iPhone, iPad and Mac operating systems, said the people, who asked not to be identified because the initiative hasn’t been announced. The password-generating and password-tracking software was unveiled on June 10 at Apple's Worldwide Developers Conference. 

The new app is backed by iCloud Keychain, a long-standing Apple tool for syncing passwords and account information across several devices. This capability was previously concealed within the company's settings app or displayed when a user logged into a website. 

Apple is attempting to encourage more people to use safe passwords and improve the privacy of its devices by making the feature available as a standalone app. However, the action increases competition with third-party apps. The new app will compete with password managers such as 1Password and LastPass, and Apple will allow users to import credentials from rival services. 

The app displays a list of user logins and divides them into categories such as accounts, Wi-Fi networks, and Passkeys, an Apple-supported password replacement that uses Face ID and Touch ID.

Like most password managers, the data can be auto-filled into websites and apps when a user logs in. The software will also function with the Vision Pro headset and Windows computers. It also supports verification codes and functions as an authentication software similar to Google Authenticator. 

The Passwords push is only one part of the WWDC event. The primary focus will be Apple's artificial intelligence project, which will include features such as notification summaries, fast photo editing, AI-generated emoji, and a more powerful Siri digital assistant. Apple will also announce a collaboration with OpenAI to utilise the ChatGPT chatbot.

Apple Working to Patch Alarming iPhone Issue

 

Apple claims to be working rapidly to resolve an issue that resulted in some iPhone alarms not setting off, allowing its sleeping users to have an unexpected lie-in. 

Many people rely on their phones as alarm clocks, and some oversleepers took to social media to gripe. A Tiktokker expressed dissatisfaction at setting "like five alarms" that failed to go off. 

Apple has stated that it is aware of the issue at hand, but has yet to explain what it believes is causing it or how users may avoid a late start. 

It's also unknown how many people are affected or if the issue is limited to specific iPhone models. The news was first made public by the early risers on NBC's Today Show, which sparked concerns. 

In the absence of an official solution, those who are losing sleep over the issue can try a few simple fixes. One is to prevent human error; therefore, double-check the phone's alarm settings and make sure the volume is turned up. 

Others pointed the finger at Apple designers, claiming that a flaw in the iPhones' "attention aware features" could be to blame.

When enabled, they allow an iPhone to detect whether a user is paying attention to their device and, if so, to automatically take action, such as lowering the volume of alerts, including alarms. 

According to Apple, they are compatible with the iPhone X and later, as well as the iPad Pro 11-inch and iPad Pro 12.9-inch. Some TikTok users speculated that if a slumbering user's face was oriented towards the screen of a bedside iPhone, depending on the phone's settings, the functionalities may be activated. 

Apple said it intends to resolve the issue quickly. But, until then, its time zone-spanning consumer base may need to dust off some old gear and replace TikTok with the more traditional - but trustworthy - tick-tock of an alarm clock.

Critical Flaw Identified in Apple's Silicon M-Series Chips – And it Can't be Patched

 

Researchers have identified a novel, unpatched security vulnerability that can allow an attacker to decrypt data on the most advanced MacBooks. 

This newly discovered vulnerability affects all Macs utilising Apple silicon, including the M1, M2, and M3 CPUs. To make matters worse, the issue is built into the architecture of these chips, so Apple can't fix it properly. Instead, any upgrades must be done before the iPhone maker launches its M4 chips later this year. 

The vulnerability, like last year's iLeakage attack, is a side channel that, under specific circumstances, allows an attacker to extract the end-to-end encryption keys. Fortunately, exploiting this flaw is challenging for an attacker, as it can take a long time. 

The new flaw was identified by a group of seven academic academics from universities across the United States, who outlined their findings in a research paper (PDF) on microarchitectural side channel attacks. 

To demonstrate how this issue could be exploited by hackers, they created GoFetch, an app that does not require root access. Instead, it merely requires the same user privileges as most third-party Mac apps. For those unfamiliar with Apple's M-series chips, they are all organised into clusters that house their respective cores. 

If the GoFetch app and the cryptography app being targeted by an attacker share the same performance cluster, GoFetch will be able to mine enough secrets to reveal a secret key. 

Patching will hinder performance

Patching this flaw will be impossible as it exists in Apple's processors, not in its software. To fully resolve the issue, the iPhone manufacturer would have to create entirely new chips. 

The researchers who found the vulnerability advise Apple to use workarounds in the company's M1, M2, and M3 chips to solve it, as there is no way to fix it. 

In order to implement these solutions, cryptographic software developers would need to incorporate remedies such as ciphertext blinding, which modifies or eliminates masks applied to sensitive variables, such as those found in encryption keys, before or after they are loaded into or saved from memory. 

Why there's no need for concern

To leverage this unfixable vulnerability in an attack, a hacker would first have to dupe a gullible Mac user into downloading and installing a malicious app on their computer. In macOS with Gatekeeper, Apple limits unsigned apps by default, which would make it much harder to install the malicious app required to carry out an attack. 

From here, this attack takes quite some time to complete. In reality, during their tests, the researchers discovered that it took anywhere between an hour and ten hours, during which time the malicious app would have to be operating continually. 

While we haven't heard anything from Apple about this unpatched issue yet, we'll update this post if we do. Until then, the researchers advised that users maintain all of the software on their Apple silicon-powered Macs up to date and apply Apple updates as soon as they become available.

Roku Data Breach: Over 15,000 Accounts Compromised; Data Sold for Pennies

 

A data breach impacting more than 15,000 consumers was revealed by streaming giant Roku. The attackers employed stolen login credentials to gain unauthorised access and make fraudulent purchases. 

Roku notified customers of the breach last Friday, stating that hackers used a technique known as "credential stuffing" to infiltrate 15,363 accounts. Credential stuffing is the use of exposed usernames and passwords from other data breaches to attempt to enter into accounts on other services. These attacks started in December 2023 and persisted until late February 2024, as per the company. 

Bleeping Computer was the first to reveal the hack, pointing out that attackers used automated tools to undertake credential-stuffing assaults on Roku. The hackers were able to bypass security protections using techniques such as specific URLs and rotating proxy servers. 

In this case, hackers probably gained login credentials from previous hacks of other websites and attempted to use them on Roku accounts. If successful, they could change the account information and take complete control, locking users out of their own accounts. 

The publication also uncovered that stolen accounts are being sold for as few as 50 cents each on hacking marketplaces. Purchasers can then employ the stored credit card information on these accounts to purchase Roku gear, such as streaming devices, soundbars, and light strips. 

Roku stated that hackers used stolen credentials to acquire streaming subscriptions such as Netflix, Hulu, and Disney Plus in some instances. The company claims to have safeguarded the impacted accounts and required password resets. Furthermore, Roku's security team has discovered and cancelled unauthorised purchases, resulting in refunds for affected users. 

Fortunately, the data breach did not compromise critical information such as social security numbers or full credit card information. So hackers should be unable to perform fraudulent transactions outside of the Roku ecosystem. However, it is recommended that you update your Roku password as a precaution. 

Even if you were not affected, this is a wake-up call that stresses the significance of proper password hygiene. Most importantly, change your passwords every few months and avoid using the same password across multiple accounts whenever possible.

Microsoft Claims Russian Hackers are Attempting to Break into Company Networks.

 

Microsoft warned on Friday that hackers affiliated to Russia's foreign intelligence were attempting to break into its systems again, using data collected from corporate emails in January to seek new access to the software behemoth whose products are widely used throughout the US national security infrastructure.

Some experts were alarmed by the news, citing concerns about the security of systems and services at Microsoft, one of the world's major software companies that offers digital services and infrastructure to the United States government. 

The tech giant revealed that the intrusions were carried out by a Russian state-sponsored outfit known as Midnight Blizzard, or Nobelium.

The Russian embassy in Washington did not immediately respond to a request for comment on Microsoft's statement, nor on Microsoft's earlier statements regarding Midnight Blizzard activity.

Microsoft reported the incident in January, stating that hackers attempted to break into company email accounts, including those of senior company executives, as well as cybersecurity, legal, and other services. 

Microsoft's vast client network makes it unsurprising that it is being attacked, according to Jerome Segura, lead threat researcher at Malwarebytes' Threatdown Labs. He said that it was concerning that the attack was still ongoing, despite Microsoft's efforts to prevent access. 

Persistent Threat

Several experts who follow Midnight Blizzard claim that the group has a history of targeting political bodies, diplomatic missions, and non-governmental organisations. Microsoft claimed in a January statement that Midnight Blizzard was probably gunning after it since the company had conducted extensive study to analyse the hacking group's activities. 

Since at least 2021, when the group was discovered to be responsible for the SolarWinds cyberattack that compromised a number of U.S. federal agencies, Microsoft's threat intelligence team has been looking into and sharing research on Nobelium.

The company stated on Friday that the ongoing attempts to compromise Microsoft are indicative of a "sustained, significant commitment of the threat actor's resources, coordination, and focus.” 

"It is apparent that Midnight Blizzard is attempting to use secrets of different types it has found," the company added. "Some of these secrets were shared between customers and Microsoft in email, and as we discover them in our exfiltrated email, we have been and are reaching out to these customers to assist them in taking mitigating measures.”
