Black Arrow Cyber Advisory 22 June 2023 – Rising Threats Facing the Apple Ecosystem, affecting Mac and iOS Devices

Black Arrow Cyber Advisory 22 June 2023 – Rising Threats Facing the Apple Ecosystem, affecting Mac and iOS Devices

Executive Summary

Open Sources Intelligence (OSINT) conducted by Black Arrow Cyber have identified a number of threats against the Apple ecosystem, with some threats reported to have nation state involvement. It is important to highlight that any internet-abled product can be a target for attackers, therefore appropriate protective controls should always be considered for all devices, especially those that are used to directly access sensitive information.

MacOS “Migraine” Vulnerability

Recently, Microsoft revealed a new macOS vulnerability dubbed “Migraine” (CVE-2023-3269) which impacts vulnerable apple devices which run macOS. The vulnerability allows an attacker with root access, which is the highest level of permissions to bypass the built in security protections, gaining remote code execution and the ability to create undeletable malware, tamper with the integrity of systems and expand the attack to the rest of the network. Apple has released a security patch which addresses this vulnerability, further details can be found at the bottom of this post.

iOS “Operation Triangulation”

Reports have identified a new mobile state-sponsored advanced persistent threat group that has been targeting iOS devices as part of an attack campaign labelled “Operation Triangulation”. the campaign is carried out using an invisible iMessage with a malicious attachment, which when executed on a device installs spyware. The deployment of the spyware is completely hidden and requires no action from the user. The spyware then quietly transmits private information to remote servers; this includes microphone recordings, photos from instant messengers, geolocation, and data about a number of other activities of the owner of the infected device. This trojan is targeting middle and upper management staff with the only workaround currently being a complete reset of the device.

Complex toolkit with files allowing backdoor capabilities targeting macOS

Bitdefender researchers have recently discovered a set of malicious files that are part of a sophisticated toolkit targeting Apple macOS systems. This malicious attack allows an attacker to gather system information, run commands, download and execute files on the victim’s machine, and to terminate the exploit script. The malicious files predominantly target macOS Monterey (version 12) and newer.

Growing Malware Threats to macOS

In addition to this, additional growing threats to macOS have been recorded in the wild. This includes:

- Threat actor groups Lazarus and BlueNoroff have been using malware dubbed “RustBucket” in financially motivated attacks to target users and steal victim’s data.  

- Reports identifying ransomware gangs, including the infamous Lockbit, developing encryption that targets macOs, specifically their M1 chips. There is no current working version of this malware.

- A rise in the use of XCSSET malware, which exploits multiple zero-days found in the Apple safari browser to download a developer version of the app on the target’s device giving it access to data from other apps such as Skype, Telegram, notes, and screen recorders.

-  An increase in the use of malware-as-a-service (MaaS), such as Atomic macOS Stealer which is capable of stealing passwords, credentials, cookies, browser data, auto-fills, and other important information and MacStealer, which extracts information from compromised systems.

- The well known 3CX attack in which the state-sponsored APT’s had altered the MacOS version of the 3CX desktop client to deliver further malware, and exfiltrate it.

Mac Vulnerabilities

Looking at the US Cybersecurity and Infrastructure Security Agency’s (CISA) Known Exploited Vulnerabilities (KEV) catalogue, there have been 36 actively recorded exploits relating to devices running macOS devices since 2021.  

What’s the risk to me or my business?

An organisation which excludes the security of any asset, relying on reputation or built-in protections alone, is leaving themselves open to potential compromise of the confidentiality, integrity and availability of the data which is held on the asset and is accessed through the asset, which includes Apple devices. Such assets include devices that are purchased by the organisation to be used as corporate devices and those that are personally owned by employees being used as part of Bring Your Own Device schemes.

What can I do?

Endpoint Protective Technologies and Security Hardening including anti-malware, Firewalls and detective solutions should be considered for all endpoints, including those that run Windows, macOS, Linux, Android and iOS.

Organisation should ensure that their asset registers are up to date and include all assets which hold or access organisational information. The better view an organisations has of its attack surface, the greater their cyber resilience will be. This should be supplemented with an effective threat intelligence programme, allowing organisations to keep up to date with emerging threats.

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.

Top Cyber Stories of the Last Week

  • How to Keep Cyber Attacks from Tanking Your Balance Sheet

According to a recent Forrester report, last year saw 1 billion records exposed in the top 35 breaches, $2.6 billion stolen in the top nine cryptocurrency breaches, and $2.7 billion in fines levied to the top 35 violators.

The average cost of a data breach reached $4.35 million in 2022, according to IBM’s Cost of a Data Breach Report for that year, which represents a 2.6% increase over the prior year, and a 12.7% increase from 2020. For ransomware, a report found the average payment in 2021 was approximately $1.85 million, more than double the $760,000 figure from 2020. These are just direct costs; indirect costs are far greater and can include lost business, lost customers, reputational loss and regulatory fines.

When it comes to managing cyber risk, corporate boards should look to understand cyber security as a strategic business enabler, understand the impacts, align risk-management with business needs, ensure the organisation supports cyber security, incorporate cyber security expertise into governance and encourage systemic resilience.

  • Company Size Doesn’t Matter When It Comes to Cyber Attacks

65% of large organisations suffered a cyber attack within the last 12 months, which is similar to the results among companies of all sizes (68%), according to a recent report. The most common security incidents were the same for all companies; these were phishing, ransomware and user account compromise, also known as business email compromise (BEC).

Smaller companies often underestimate their risk, with the reasoning that cyber criminals want the biggest targets as they will likely have more intellectual property, however all businesses have valuable data and are therefore a target. Additionally, smaller organisations can sometimes be seen as a way into larger organisations that use their services.

  • ‘Exceptional’ Cyber Attacks Now Normal, says BT Security Chief

The threat of cyber attacks is growing at an “unprecedented” pace, according to the chief security officer at multinational teleco BT, Howard Watson, but it is not just large organisations such as BT who will be impacted by this increase.

Watson highlighted that the increase in sophisticated technology poses the biggest threat in the long run: “Technological advancement, as ever, is a double-edged sword in security. Quantum and AI have great potential for benefits in the right hands, or to cause massive damage in the wrong hands. But we know that cyber criminals will utilise these technologies, so we have to be able to respond in kind.”  Adding to this, the chief security officer highlighted that events that were previously considered as ‘exceptional’ need to be assessed and planned for as a probability, rather than a possibility.

  • How State-Sponsored/Advanced Persistent Threat Groups (APTs) Target SMBs

Small and medium businesses (SMBs) are not exempt from being targeted by advanced persistent threat (APT) actors, according to Proofpoint researchers who collected data from over 200,000 SMB customers. Proofpoint identified a rise in phishing campaigns originating from such state-sponsored APT groups, who are highly skilled and typically state-sponsored groups with distinct strategic goals. These goals range from espionage and intellectual property theft to destructive attacks, state-sponsored financial theft, and disinformation campaigns.

Unfortunately, SMBs often lack adequate cyber security measures, making them vulnerable to all kinds of cyber threats. APT actors exploit this weakness by targeting SMBs as a stepping stone towards achieving their larger goals.

Alongside phishing campaigns, it was identified that APTs are increasingly targeting regional outsourced IT providers/Managed Service Providers (MSPs) to mount supply chain attacks. By compromising regional MSPs within geographies that align with the strategic collection requirements of APT actors, threat actors can gain access to multiple SMBs to extract sensitive information or execute further attacks.

  • Phishing Campaigns Thrive as Evasive Tactics Outsmart Conventional Detection

According to research, 2022 saw a 25% increase in the use of phishing kits. These phishing kits are a set of tools that enable cyber criminals to effortlessly create and maintain large scale sophisticated phishing campaigns. It is this sophistication that allows cyber criminals to circumnavigate conventional detections; in fact, the research found a 40% increase in the use of anti-bot technologies designed to prevent automated scanners from identifying content as phishing.

In some cases (11% of observed phishing kits) malicious links would not be detected when tested by anti-phishing controls because those controls do not use the exact device parameters, geolocation and referrer of the intended target victim’s profile; therefore the malicious link is allowed to be delivered to the intended target.

  • Don't be Polite When you Get a Text from a Wrong Number

You should immediately be suspicious of any text you get from a number not in your contacts, even if it may be innocent looking. Your first reaction may be to be polite and let them know they have the wrong number, but this person is a stranger. Strangely, despite teaching our children not to talk to strangers, many are comfortable with divulging information to them. Although letting them know they made a mistake seems harmless, responding opens you up to being scammed and you’ve just let them know you’re a real person. Every bit of helpful information you provide has the potential to be leveraged by an attacker.

  • Capita Cyber Attack: 90 Downstream Organisations Reported Data Breaches

90 organisations have reported breaches of personal information held by Capita after the outsourcing group had suffered a cyber attack, according to Britain’s data watchdog. The attack on Capita, which occurred in March, is still impacting businesses, with the UK Information Commissioners Office (ICO) making enquiries. Organisations must notify the ICO within 72 hours of becoming aware of a personal data breach.

The impact of the attack, and its knock-on effect, highlights the need for organisations to consider their third party security, no matter the size of the third party they use.

  • Travel-Themed Phishing, BEC Campaigns Get Smarter as Summer Season Arrives

A recent survey from McAfee found that nearly a third (30%) of adults have fallen victim or know someone who has fallen victim to an online scam when bargain hunting for travel deals during the summer season, with a full two-thirds of victims losing up to $1,000.

This has extended to the corporate environment, with threat actors impersonating the HR department and exploiting the trust users place in their employers, a report has found. The attack leverages regular HR procedures associated with holiday requests and taps into the anticipation and excitement surrounding the summer travel season, to capitalise on exploiting the user.

  • Organisations Spend 100 Hours Battling Post-Delivery Email Threats

Nearly every victim of a spear-phishing attack in the last 12 months saw impacts on their organisation, including malware infections, stolen data, and reputational damage, according to Barracuda Networks. The research shows that cyber criminals continue to barrage organisations with targeted email attacks, and many companies are struggling to keep up.

While spear-phishing attacks are low-volume, they are widespread and highly successful compared to other types of email attacks. On average, organisations take nearly 100 hours to identify, respond to, and remediate a post-deliver email threat: 43 hours to detect the attack and 56 hours to respond and remediate after the attack is detected.

Users at companies with more than a 50% remote workforce report higher levels of suspicious emails: 12 per day on average, compared to 9 per day for those with less than a 50% remote workforce. Companies with more than a 50% remote workforce also reported that it takes longer to both detect and respond to email security incidents: 55 hours to detect and 63 hours to respond and mitigate, compared to an average of 36 hours and 51 hours respectively for organisations with fewer remote workers.

  • Ransomware Gangs Adopting Business-like Practices to Boost Profits

Ransomware gangs are using a variety of business-like practices to boost profits, making it more difficult for defenders to differentiate various groups, a new report by WithSecure has surmised. This move towards mirroring legitimate businesses practices means that tactics, techniques and procedures (TTPs) are blurring.

The underground marketplace now includes entities including ransomware-as-a-service (RaaS) groups, Initial Access Brokers (IAB), crypter-as-a-service (CaaS), cryptojackers, malware-as-a-service (MaaS) groups and nation-state actors. This allows nation-states to use tools available on the underground market to gain access to networks and systems without being detected. Ultimately, this trend towards professionalisation makes the expertise and resources to attack organisations accessible to lesser-skilled or poorly resourced threat actors.

  • The Sobering Truth about Ransomware—for the 80% Who Paid Up

Newly published research of 1,200 organisations impacted by ransomware reveals a sobering truth that awaits many of those who decide to pay the ransom. According to research, 80% of the organisations surveyed decided to pay the demanded ransom in order to both end the ongoing cyber attack and recover otherwise lost data. This is despite 41% of those organisations having a “do not pay” policy in place, which only goes to reinforce the cold hard fact that cyber crime isn’t an easy landscape to navigate. This is something that’s especially true when your business is facing the real-world impact of dealing with a ransomware attack.

Of the 960 organisations that paid a ransom, 201 of them (21%) were still unable to recover their lost data. The same number also reported that ransomware attacks were now excluded from their insurance policies. Of those organisations with cyber insurance cover, 74% reported a rise in premiums. Another report, published by Sophos, revealed that 32% of those surveyed opted to pay the ransom but a shocking 92% failed to recover all their data and 29% were unable to recover more than half of the encrypted data.

Some groups have switched to stealing sensitive customer or corporate data instead, with the ransom demanded in return for them not selling it to the highest bidder or publishing it online. Many groups combine the two for a double extortion ransomware attack.

  • The Great CISO Resignation: Why Security Leaders are Quitting in Droves

With the rise in AI tools such as ChatGPT broadening an attacker’s arsenal, this places greater and greater pressure on security leaders who are already dealing with shrinking budgets, skeleton crew staff and a conglomeration of security tools and protocols — so much so that they are increasingly quitting. A recent report found that nearly a third (32%) of CISOs in the US and UK were considering leaving their current organisation and 9 out of 10 reported themselves as “moderately” or “tremendously” stressed.

This so-called Great CISO Resignation is concerning, because what happens when there’s nobody guarding the gate and rallying the troops?

  • When is it Time for a Cyber Hygiene Audit?

Effective cyber hygiene practices limit threats against your systems, devices and users, preventing breaches that could compromise sensitive business information, database information, and personal data. But cyber hygiene isn’t a static or one-off process. It requires routine execution and, occasionally, a full audit. This audit typically covers a range of aspects including encryption, documentation, authentication, patches, security and ongoing cyber hygiene.

Good cyber hygiene is a necessary part of maintaining IT security. Setting up processes and procedures within your organisation’s regular operating procedures is an effective way to maintain cyber hygiene. Although the responsibilities may differ by position, everyone in the organisation plays a role.

An audit provides important information on where and where you need to improve. It also provides a baseline for measuring improvement and effectiveness. The key to success is to integrate hygiene into routine process starting top down from policies into every part of the business and making use of third party experts to help aid in the process.
