A critical iPhone and iPad bug that lurked for 8 years may be under active attack – Ars Technica

A critical bug that has lurked in iPhones and iPads for eight years appears to be under active attack by sophisticated hackers to hack the devices of high-profile targets, a security firm reported on Wednesday.

The exploit is triggered by sending booby-trapped emails that, in some cases, require no interaction at all and, in other cases, require only that a user open the message, researchers from ZecOps said in a post. The malicious emails allow attackers to run code in the context of the default mail apps, which make it possible to read, modify, or delete messages. The researchers suspect the attackers are combining the zero-day with a separate exploit that gives full control over the device. The vulnerability dates back to iOS 6 released in 2012. Attackers have been exploiting the bug since 2018 and possibly earlier.

Enormous scope

“With very limited data we were able to see that at least six organizations were impacted by this vulnerability— and the full scope of abuse of this vulnerability is enormous,” ZecOps researchers wrote. “We are confident that a patch must be provided for such issues with public triggers ASAP.”

Targets from the six organizations include:

  • Individuals from a Fortune 500 organization in North America
  • An executive from a carrier in Japan
  • A VIP from Germany
  • Managed security services providers in Saudi Arabia and Israel
  • A journalist in Europe
  • Suspected: An executive from a Swiss enterprise

Zerodays, or vulnerabilities that are known to attackers but not the manufacturer or the general public, are rarely exploited in the wild against against users of iPhones and iPads. Some of the only known incidents a 2016 attack that installed spyware on the phone of a dissident in the United Arab Emirates, a WhatsApp exploit in May of last year that was transmitted with a simple phone call, and attacks that Google disclosed last August.

Apple has currently patched the flaw in the beta for iOS 13.4.5. At the time this post went live, a fix in the general release had not yet been released.

Malicious mails that trigger the flaw work by consuming device memory and then exploiting a heap overflow, which is a type of buffer overflow that exploits an allocation flaw in memory reserved for dynamic operations. By filling the heap with junk data, the exploit is able to inject malicious code that then gets executed. The code triggers strings that include 4141…41, which are commonly used by exploit developers. The researchers believe the exploit then deletes the mail.

A protection known as address space layout randomization prevents attackers from knowing the memory location of this code and thus executing in a way that takes control of the device. As a result, the device or application merely crashes. To overcome this security measure, attackers must exploit a separate bug that reveals the hidden memory location.

Little or no sign of attack

The malicious mails need not be prohibitively large. Normal-size emails can consume enough RAM using rich text format documents, multi-part content, or other methods. Other than a temporary device slowdown, targets running iOS 13 aren’t likely to notice any signs that they’re under attack. In the event that the exploit fails on a device running iOS 12, meanwhile, the device will show a message that says “This message has no content.”

ZecOps said the attacks are narrowly targeted but provided only limited clues about the hackers carrying them out or targets who were on the receiving end.

“We believe that these attacks are correlative with at least one nation-state threat operator or a nation-state that purchased the exploit from a third-party researcher in a Proof of Concept (POC) grade and used ‘as-is’ or with minor modifications (hence the 4141..41 strings),” ZecOps researchers wrote. “While ZecOps refrain from attributing these attacks to a specific threat actor, we are aware that at least one ‘hackers-for-hire’ organization is selling exploits using vulnerabilities that leverage email addresses as a main identifier.”

The most visible third-party organization selling advanced smartphone exploits is Israel-based NSO Group, whose iOS and Android exploits over the past year have been found being used against activists, Facebook users, and undisclosed targets. NSO Group has come under sharp criticism for selling its wares in countries with poor human-rights records. In recent months, the company has vowed to serve only organizations with better track records.

It’s generally against security community norms to disclose vulnerabilities without giving manufacturers time to release security patches. ZecOps said it released its research ahead of a general release fix because the zeroday alone isn’t enough to infect phones, the bugs had already been mentioned in the beta release, and the urgency created by the six organizations the firm believes are under active attack

To prevent attacks until Apple releases a general-availability patch, users can either install the beta 13.4.5 or use an alternate email app such as Gmail or Outlook. Apple representatives didn’t respond to an email seeking comment for this post.

Ottawa orders TikTok’s Canadian arm to be dissolved

Published

 on

 

The federal government is ordering the dissolution of TikTok’s Canadian business after a national security review of the Chinese company behind the social media platform, but stopped short of ordering people to stay off the app.

Industry Minister François-Philippe Champagne announced the government’s “wind up” demand Wednesday, saying it is meant to address “risks” related to ByteDance Ltd.’s establishment of TikTok Technology Canada Inc.

“The decision was based on the information and evidence collected over the course of the review and on the advice of Canada’s security and intelligence community and other government partners,” he said in a statement.

The announcement added that the government is not blocking Canadians’ access to the TikTok application or their ability to create content.

However, it urged people to “adopt good cybersecurity practices and assess the possible risks of using social media platforms and applications, including how their information is likely to be protected, managed, used and shared by foreign actors, as well as to be aware of which country’s laws apply.”

Champagne’s office did not immediately respond to a request for comment seeking details about what evidence led to the government’s dissolution demand, how long ByteDance has to comply and why the app is not being banned.

A TikTok spokesperson said in a statement that the shutdown of its Canadian offices will mean the loss of hundreds of well-paying local jobs.

“We will challenge this order in court,” the spokesperson said.

“The TikTok platform will remain available for creators to find an audience, explore new interests and for businesses to thrive.”

The federal Liberals ordered a national security review of TikTok in September 2023, but it was not public knowledge until The Canadian Press reported in March that it was investigating the company.

At the time, it said the review was based on the expansion of a business, which it said constituted the establishment of a new Canadian entity. It declined to provide any further details about what expansion it was reviewing.

A government database showed a notification of new business from TikTok in June 2023. It said Network Sense Ventures Ltd. in Toronto and Vancouver would engage in “marketing, advertising, and content/creator development activities in relation to the use of the TikTok app in Canada.”

Even before the review, ByteDance and TikTok were lightning rod for privacy and safety concerns because Chinese national security laws compel organizations in the country to assist with intelligence gathering.

Such concerns led the U.S. House of Representatives to pass a bill in March designed to ban TikTok unless its China-based owner sells its stake in the business.

Champagne’s office has maintained Canada’s review was not related to the U.S. bill, which has yet to pass.

Canada’s review was carried out through the Investment Canada Act, which allows the government to investigate any foreign investment with potential to might harm national security.

While cabinet can make investors sell parts of the business or shares, Champagne has said the act doesn’t allow him to disclose details of the review.

Wednesday’s dissolution order was made in accordance with the act.

The federal government banned TikTok from its mobile devices in February 2023 following the launch of an investigation into the company by federal and provincial privacy commissioners.

Here is how to prepare your online accounts for when you die

Published

 on

 

LONDON (AP) — Most people have accumulated a pile of data — selfies, emails, videos and more — on their social media and digital accounts over their lifetimes. What happens to it when we die?

It’s wise to draft a will spelling out who inherits your physical assets after you’re gone, but don’t forget to take care of your digital estate too. Friends and family might treasure files and posts you’ve left behind, but they could get lost in digital purgatory after you pass away unless you take some simple steps.

Here’s how you can prepare your digital life for your survivors:

Apple

The iPhone maker lets you nominate a “ legacy contact ” who can access your Apple account’s data after you die. The company says it’s a secure way to give trusted people access to photos, files and messages. To set it up you’ll need an Apple device with a fairly recent operating system — iPhones and iPads need iOS or iPadOS 15.2 and MacBooks needs macOS Monterey 12.1.

For iPhones, go to settings, tap Sign-in & Security and then Legacy Contact. You can name one or more people, and they don’t need an Apple ID or device.

You’ll have to share an access key with your contact. It can be a digital version sent electronically, or you can print a copy or save it as a screenshot or PDF.

Take note that there are some types of files you won’t be able to pass on — including digital rights-protected music, movies and passwords stored in Apple’s password manager. Legacy contacts can only access a deceased user’s account for three years before Apple deletes the account.

Google

Google takes a different approach with its Inactive Account Manager, which allows you to share your data with someone if it notices that you’ve stopped using your account.

When setting it up, you need to decide how long Google should wait — from three to 18 months — before considering your account inactive. Once that time is up, Google can notify up to 10 people.

You can write a message informing them you’ve stopped using the account, and, optionally, include a link to download your data. You can choose what types of data they can access — including emails, photos, calendar entries and YouTube videos.

There’s also an option to automatically delete your account after three months of inactivity, so your contacts will have to download any data before that deadline.

Facebook and Instagram

Some social media platforms can preserve accounts for people who have died so that friends and family can honor their memories.

When users of Facebook or Instagram die, parent company Meta says it can memorialize the account if it gets a “valid request” from a friend or family member. Requests can be submitted through an online form.

The social media company strongly recommends Facebook users add a legacy contact to look after their memorial accounts. Legacy contacts can do things like respond to new friend requests and update pinned posts, but they can’t read private messages or remove or alter previous posts. You can only choose one person, who also has to have a Facebook account.

You can also ask Facebook or Instagram to delete a deceased user’s account if you’re a close family member or an executor. You’ll need to send in documents like a death certificate.

TikTok

The video-sharing platform says that if a user has died, people can submit a request to memorialize the account through the settings menu. Go to the Report a Problem section, then Account and profile, then Manage account, where you can report a deceased user.

Once an account has been memorialized, it will be labeled “Remembering.” No one will be able to log into the account, which prevents anyone from editing the profile or using the account to post new content or send messages.

X

It’s not possible to nominate a legacy contact on Elon Musk’s social media site. But family members or an authorized person can submit a request to deactivate a deceased user’s account.

Passwords

Besides the major online services, you’ll probably have dozens if not hundreds of other digital accounts that your survivors might need to access. You could just write all your login credentials down in a notebook and put it somewhere safe. But making a physical copy presents its own vulnerabilities. What if you lose track of it? What if someone finds it?

Instead, consider a password manager that has an emergency access feature. Password managers are digital vaults that you can use to store all your credentials. Some, like Keeper,Bitwarden and NordPass, allow users to nominate one or more trusted contacts who can access their keys in case of an emergency such as a death.

But there are a few catches: Those contacts also need to use the same password manager and you might have to pay for the service.

Google’s partnership with AI startup Anthropic faces a UK competition investigation

Published

 on

 

LONDON (AP) — Britain’s competition watchdog said Thursday it’s opening a formal investigation into Google’s partnership with artificial intelligence startup Anthropic.

The Competition and Markets Authority said it has “sufficient information” to launch an initial probe after it sought input earlier this year on whether the deal would stifle competition.

The CMA has until Dec. 19 to decide whether to approve the deal or escalate its investigation.

“Google is committed to building the most open and innovative AI ecosystem in the world,” the company said. “Anthropic is free to use multiple cloud providers and does, and we don’t demand exclusive tech rights.”

San Francisco-based Anthropic was founded in 2021 by siblings Dario and Daniela Amodei, who previously worked at ChatGPT maker OpenAI. The company has focused on increasing the safety and reliability of AI models. Google reportedly agreed last year to make a multibillion-dollar investment in Anthropic, which has a popular chatbot named Claude.

Anthropic said it’s cooperating with the regulator and will provide “the complete picture about Google’s investment and our commercial collaboration.”

“We are an independent company and none of our strategic partnerships or investor relationships diminish the independence of our corporate governance or our freedom to partner with others,” it said in a statement.

The U.K. regulator has been scrutinizing a raft of AI deals as investment money floods into the industry to capitalize on the artificial intelligence boom. Last month it cleared Anthropic’s $4 billion deal with Amazon and it has also signed off on Microsoft’s deals with two other AI startups, Inflection and Mistral.
