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

Cloud Hosting Firm Loses All Customer Data After Ransomware Attack

CloudNordic, a Danish cloud hosting provider, has told customers to consider all of their data as having been lost following a ransomware infection that encrypted the large Danish cloud provider. The threat actors had destroyed the organisation’s backups, which prevented the firm from recovering effectively. The attack also impacted AzeroCloud, which is owned by the same company.

Worryingly, many organisations believe that having backups and using the cloud is enough for them to be able to recover from any cyber incident; unfortunately, as shown in the CloudNordic and AzeroCloud attacks, it is not enough. Organisations need to have a recovery plan in place which is tested and improved, to best strengthen themselves in the event of a cyber incident.

Would You Infect Others to Rid Yourself of Ransomware?

Hackers continually develop ransomware with new and creative attack methods that keep internet security professionals on their toes and pose challenges for people trying to detect threats. Victims of ransomware usually see messages asking them to pay for file access restoration; however, the Popcorn Time ransomware group takes a different approach to getting victims involved.

The Popcorn Time ransomware approach works via the referral method. The ransomware group is willing to give victims access to their files if they send the referral link to two other people, extending the attacker’s reach. Most people would hesitate to distribute a ransomware link through email, WhatsApp, or another method that is easy for victims to identify them as the perpetrators. Law enforcement bodies categorise ransomware attacks as crimes that come with hefty fines and prison time. Even those choosing to send the links to people they know face disastrous consequences beyond law enforcement, including the loss of jobs and relationships.

Artificial Intelligence and USBs Drive 8% Rise in Cyber Attacks

Checkpoint’s 2023 Mid-Year Security Report shows an 8% surge in global weekly cyber attacks during Q2, marking the most significant increase in two years. The report highlights the fusion of advanced artificial intelligence (AI) technology with traditional tools like USB devices used for disruptive cyber attacks.

Other significant findings include the evolution of ransomware tactics. The report found that ransomware groups are exploiting vulnerabilities in common corporate software and shifting focus from encrypting data to stealing it. USB devices have resurfaced as threats, employed by both state-affiliated groups and cyber-criminals to distribute malware globally. The misuse of AI has escalated, as attackers use generative AI tools for phishing emails, keystroke monitoring malware and basic ransomware code.

Ransomware Attacks Broke Records in July, Mainly Driven By One Group

A number of ransomware actors are utilising the threat of releasing sensitive data to get organisations to pay ransoms; in some cases this is combined with encryption to give the actor two avenues of payment. A report has found there were over 500 attacks last month, an increase of 153% compared to one year ago, and a 16% increase compared to June. Within Europe, there was a 59% increase in ransomware attacks from June to July.

Part of the significant rise is due to the ransomware group called Cl0p, whose attack on the MOVEit software has accounted for hundreds of victims this year. The Cl0p ransomware group has kept its promise to publish files on the clearweb of all its victims if contact was not made. The clearweb is simply what we know as the internet; anyone can access it. As such, there will be many organisations who are now having their sensitive data published and readily viewable for anyone who has access to the internet.

Cyber Risk in The Boardroom

The relationship between the CISO and the wider boardroom has become increasingly cooperative, with 77% of CEO’s seeing cyber as a strategic function and a potential source of competitive advantage. While it is ultimately up to the board to take steps to keep cybersecurity high on the agenda, the CISO also has a responsibility to press the message and bridge any gaps.

CISOs must deliver concerns, strategies and recommendations in a business-first manner, while avoiding jargon and overly technical language. Attracting and retaining good quality senior security professionals is very challenging in the current market and Black Arrow offer a fractional CISO service, giving access to a whole team of specialists with wider expertise, experience and backgrounds, for less than the cost of hiring one individual.

Malware-Infected Advertising Grows Ever More Sophisticated, And More Damaging

The malware exploits known as malware-infected ads, or malvertising, have been around for decades, but new reports point to a steady rise in efficacy. With malvertising, the infected ads are typically placed on legitimate ad networks, which makes them more difficult to spot and remove. The technique continues to use more and more sophisticated mechanisms for getting their infections spread throughout the web and keeping them running for a long time. The exploits can operate in one of several ways, including intercepting a user’s clickstream on random hyperlinks and substituting them with redirects to advertising websites.

Adblockers either on endpoints or at the network level can also help to prevent malvertising from causing harm.

Cyber Security is Everyone’s Responsibility

A recent survey found that 41% of respondents said that poor quality training, or a lack of training altogether, and insider threats were impacting their organisation’s security. Cyber security involves everyone as any employee can be an entry point for a cyber incident, but they also have the power to prevent one. It is important to make sure all employees are provided adequate training. Not every role requires the same training however, so it is important for organisations to identify and provide training that is appropriate to employees. Black Arrow provide live in person and online instructor lead cyber security training, both through Cyber Risk and Governance Workshops for Senior Leadership and Awareness, Behaviour and Culture Training for employees and contractors.

QR Code Hacks Are Another Thing to Worry About Now

One of the upcoming technologies thrust upon us is QR codes. At this point, you can find them at most restaurants and parking sites. You simply scan the code and you are taken to the relevant site, for example, the menu for the restaurant. Attackers have cottoned on to this and started to use QR codes in phishing attacks; the idea being that the victim will scan the code without scrutinising it and be taken to a malicious website instead.

Security Basics Aren’t So Basic Anymore

The basics of cyber security, it turns out, aren’t so basic anymore. What was considered basic has moved way beyond just having firewalls and antivirus, and the most basic controls nowadays include more advanced controls such as robust identity and access management, multi-factor authentication (MFA) and patching and vulnerability management. Many of these now basic controls are lacking or non-existent across the economy according to cyber security experts. A report found that only 28% of Microsoft users had MFA enabled as 2022 closed.

You can’t solve all the problems at once. However, progress on these fronts also relies heavily on the need for a cultural shift. Organisations need to get to the point where they view cyber security in the same light as locks on doors and seatbelts in cars.

Apple MacOS Security Myths

Apple has maintained a reputation as being more secure than other manufacturers, and whilst Apple has put many different security mechanisms into its operating system, no technology is bulletproof. Assuming an Apple device is invulnerable can lead users to believe that their Mac will not get viruses or be subject to a plethora of other cyber threats. As a result, this can lead to poor cyber hygiene from the individual, as they assume they are safe regardless of what they do. Apple users need to remain every bit as aware of risks, social engineering, keeping devices up to date, and having appropriate security controls.

Security Leaders Report Misalignment of Investments and Risk Reduction

The cyber risk landscape was analysed in a recent report that examined the amount of risk that organisations are willing to accept, their resource constraints and key priorities for approaching cyber risk in the future. The report found 66% of respondents indicating that they have limited visibility and insight into their cyber risk profiles, hindering their ability to prioritise investments and allocate resources effectively. 67% of organisations experienced a breach requiring attention within the last two years despite having traditional threat-based security measures in place. Further, 61% of security executives expressed concerns over the current misalignment between cyber security investments and their organisation's risk reduction priorities.

Many CISOs Tout SaaS (Cloud) Cyber Security Confidence, but 79% Admit to Incidents

Cyber security, IT, and business leaders alike recognise SaaS (cloud) cyber security as an increasingly important part of the cyber threat landscape. And at first glance, respondents appear generally optimistic about their SaaS cyber security as 85% answered that they are confident or very confident in their company's or customer's data security in sanctioned SaaS apps.

Despite the confidence, 79% of respondents confirmed that their organisation had identified SaaS cyber security incidents over the past 12 months. Many of those incidents occurred in environments with cyber security policies in place and enforced, as 66% of respondents claimed in their responses.

If You Ever Used Duolingo, Watch Out for Phishing Email

Users of Duolingo, past and present, should be wary of phishing emails as data on about 2.6 million accounts were scraped through an exposed application programming interface (API), and then offered on a hacking forum back in January. Login and real names, email addresses, phone numbers, and courses studied were part of the collection, which went for $1,500. Now that data has resurfaced on a different forum, and at a substantially lower cost of just a few dollars, users of the service can expect this data to be used in fresh phishing campaigns.

91% of Security and IT Professionals: Criminals are Already Using AI in Email Attacks

Recent research found that 91% of security and IT professionals are noticing cyber criminals already using AI as part of email attack campaigns, with 74% indicating they have experienced an increase in the use of AI by cyber criminals in the past six months. This is worrying as 52% reported that email security is among one of their top three concerns.

Organisations need to make sure that their technologies, procedures and policies are updated to factor in AI-enabled email attacks to help reduce the risk they pose to the organisation. Such improvements should also include employees.

Black Arrow Cyber Alert 07 March 2023 – ACTION REQUIRED: New Hiatus Hacking Campaign Targets DrayTek Routers to Spy on Businesses

Black Arrow Cyber Alert 07 March 2023 – ACTION REQUIRED: New Hiatus Hacking Campaign Targets DrayTek Routers to Spy on Businesses

Executive Summary

An ongoing hacking campaign known as “Hiatus” is targeting DrayTek Vigour router models 2960 and 3900 to monitor and steal data from businesses.

What’s the risk to my business?

If exploited successfully, the attacker is able to remotely execute commands on the router, and monitor and control traffic that passes through the router including file-transfer and email communications.

Technical Summary:

Research by Black Lotus Labs has found the campaign involves following:

  • A Bash script to deploy two executables to the targetdevice, post-exploitation. These are:

    • HIATUS Remote Access Trojan

    • A variant of ‘tcpdump’ that enables packet capture

Once this script has been executed the ‘HiatusRAT’ and ‘tcpdump’ variant are downloaded to a directory created by the script located at ‘/database/.updata’ and are then executed. The malware will listen on TCP port 8816 and if this port is already in use, the process on that port is terminated  so that the malware can use it instead. Once the malware has been sucessfully enabled on this port, a second process collects information about the victim device and sends it to a Command and Control (C2) server operated by the attacker (104.250.58.192); an additional C2 server (46.8.113.227) is also used by the attacker to receive information captured by the packet-capture tool . The packet capture tool observes ports associated with mail server and FTP connections, this include TCP ports 21, 25, 110, 143.

What can I do?

It is not currently known how the DrayTek routers have been initially compromised and Draytek have not yet released a security update to resolve any associated known vulnerability. The following actions can be taken to help mitigate and identify if a device has been impacted:

  • Prevent outbound network traffic on TCP port 8816, to disable the malware’s outbound communication.

  • Block network traffic to or from the following IP addresses: 104.250.58.192 and 46.8.113.227

  • Check the following location on vulnerable devices for any files in that location, as this would be an indicator of compromise (IoC): ‘database’ and ‘/database/.updata’

  • Configure continuous security monitoring to detect anomalous activity that may be indicative of a compromise.

Further indicators of compromise can be found here: https://github.com/blacklotuslabs/IOCs/blob/main/Hiatus_IoCs.txt
