Black Arrow Cyber Threat Briefing 13 May 2022

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

• UK, US Intelligence Agencies Warn Managed Service Providers, including External IT Providers, Are Now Prime Targets for Cyber Attacks

The Five Eyes coalition of international cyber security authorities, this week issued an advisory to warn managed service providers (MSPs), including external IT providers, of an escalating threat of attack from both everyday cyber criminals and state-sponsored threat actors.

MSPs provide or operate information and communications technology services.

With input from cyber security leaders from Australia, Canada, New Zealand, the UK and the US, the NSA provided recommendations to help bolster their cyber defences, including:

• Finding and disabling dormant accounts.

• Implementing and enforcing multifactor authentication on accounts.

• Ensuring contracts clearly map out who owns and is responsible for securing data.

Malicious actors are targeting MSPs to break into their customers' networks and deploy ransomware, steal data, and spy on them, the Five Eyes authorities have formally warned in a joint security alert.

"The UK, Australian, Canadian, New Zealand, and US cyber security authorities expect malicious cyber actors — including state-sponsored advanced persistent threat (APT) groups — to step up their targeting of MSPs in their efforts to exploit provider-customer network trust relationships," the alert warned.

These types of supply-chain or "island-hopping" attacks can prove very lucrative for cyber criminals because once they break into an MSP, they gain access to all of the customers' networks and data being managed, and in turn commit computer crimes and fraud against those customers' customers.

• Wannacry – 5 Years On, 68% Of Enterprises Are Still at Risk

5 years on from one of the world’s most damaging ransomware attacks, research from network detection and response leader ExtraHop has found that 68% of enterprises are still running insecure protocol that were exploited by the North Korean ransomware.

The events of 12 May 2017 live on in cyber security lore. WannaCry revealed just how extensive the damage caused by ransomware can be if deployed in large scale – from downtime to ransom paid to reputational damage. Yet despite the danger, huge numbers of organisations are still running SMBv1, the protocol exploited in the WannaCry attacks that has been publicly deprecated since 2014.

• You Can’t Eliminate Cyber Attacks, So Focus on Reducing the Blast Radius

Given it is impossible to prevent all cyber attacks, many organisations should look to reduce the size of the company’s attack surface and the limit the “blast radius” of a potential attack.

There is a danger that the biggest risk concerning cyber attacks is that we’re becoming desensitised to them. After all, businesses experience a ransomware attack every 11 seconds—the majority of which the public never hears about. Faced with this reality, it may seem like efforts to safeguard the enterprise are futile. But that’s all the more reason to strengthen your resolve—and switch up your cyber defence strategy.

The core of this strategy should be the concept of “reducing the blast radius” of an attack, and since you can’t completely eliminate cyber attacks, you need to take steps to contain the impact.

This strategy should contain basic blocking and also consider things such as Zero Trust for remote access, traffic inspection, software-based micro-segmentation and other practical measures to reduce your attack surface.

• Just In Time? Bosses Are Finally Waking Up to The Cyber Security Threat

Boardrooms have a reputation for not paying much attention to cyber security, but it could be that executives are finally keen to take more interest in securing the systems and networks their businesses rely on.

Senior figures from American, British and Australian cyber security agencies have said that business execs are now more aware of cyber threats and are actively engaging with their chief information security officer (CISO) and information security teams.

Chief execs are starting to ask their CISOs the right questions, rather than leaving them to it because they don't have to understand complex technology. It does feel like a much more engaging strategic conversation, but there can still be a disconnect between knowing what needs to happen, then actually budgeting for and implementing a cyber security strategy.

• Most Organisations Hit by Ransomware Would Pay Up If Hit Again

Almost nine in 10 organisations that have suffered a ransomware attack would choose to pay the ransom if hit again, according to a new report, compared with two-thirds of those that have not experienced an attack.

The findings come from a report titled "How business executives perceive ransomware threat" by security company Kaspersky, which states that ransomware has become an ever-present threat, with 64 percent of companies surveyed already having suffered an attack, but more worryingly, that executives seem to believe that paying the ransom is a reliable way of addressing the issue.

The report is based on research involving 900 respondents across North America, South America, Africa, Russia, Europe, and Asia-Pacific. The respondents were in senior non-IT management roles at companies between 50 and 1,000 employees.

Kaspersky claims that in 88 percent of organisations that have had to deal with a ransomware incident, business leaders said they would choose to pay the money if faced with another attack. In contrast, among those that have not so far suffered a ransomware attack, only 67 percent would be willing to pay, and they would be less inclined to do so immediately.

• 31,000 FTSE 100 Logins Found on Dark Web

Researchers with Outpost24 are reporting over 31,000 corporate credentials for many of the UK’s leading FTSE 100 firms on the dark web. These are the 100 biggest companies listed on the London Stock Exchange by market capitalisation. The researchers used their threat monitoring and auditing tool Blueliv to search dark web sites for the breached credentials.

Key findings from stolen and leaked credentials study:

• The majority (81%) of the companies within the FTSE 100 had at least one credential compromised and exposed on the dark web

• 31,135 total stolen and leaked credentials detected for FTSE 100 companies, with 38% disclosed on the underground in the past 12 months

• Nearly half (42%) of FTSE 100 companies have more than 500 compromised credentials exposed on the dark web

• Up to 20% of credentials are stolen via malware infection and stealers

• 11% disclosed in the last 3 months (21% in the last 6 months and over 68% have been exposed for over 12 months)

• Over 60% of stolen credentials came from 3 industries – IT/Telecom (23%), Energy and Utility (22%) and Finance (21%)

• IT/Telecoms industry is the most at risk with the highest total amount (7,303) and average stolen credentials per company (730), they are most affected by malware infection and have the most amount of stolen credentials disclosed in the last 3 months

• On average, healthcare has the highest number of stolen credentials per company (485) from data breach as they found themselves increasingly in the cyber criminals’ crosshairs since the pandemic.

• Ransomware: How Executives Should Prepare Given the Current Threat Landscape

As the number of ransomware attacks continue to increase, the response at C-level must be swift and decisive.

Top executives are increasingly dreading the phone call from their fellow employee notifying them that their company has been hit by a cyber attack. Nearly every week in 2021 and early 2022, a prominent organisation has been in the media spotlight as their public relations team struggles to explain how they were attacked and how they can regain consumer confidence. A recent survey showed that 37 percent of organisations surveyed had been affected by ransomware attacks in the last year.

Worse, the days when executive leadership teams could fully delegate responsibility to a CISO are over. Regardless of reality, surveys have shown that about 40 percent of the public perception of fault for a ransomware attack lands squarely on the CEO’s shoulders, and that 36 percent of attacks result in the loss of C-level talent. While executive involvement in the security program does not guarantee a successful defence, it does give the executive leadership team (ELT) a degree of ownership of the final product, as well as the ability to speak confidently and knowledgeably to the public.

• What Your Cyber Insurance Application Form Can Tell You About Ransomware Readiness

The annual cyber insurance application form shows what the carriers think you should be doing to best prevent and recover from ransomware attacks. Pay attention.

If it’s the time of year for you to fill out the annual cyber insurance policy application, you will see how the focus for insurance firms is changing. Each year you can get an insight into what insurance vendors are using to rate the risks and threats to your business and what they are stressing firms should have in place as best practice or what they are expecting you should have in place as a baseline set of controls. Not having them in place could affect insurance rates, whether you are able to get cyber coverage at all, or crucially whether they would pay out in the event of you having to make a claim.

This year you might find more questions specifically around ransomware prevention techniques and protections, from Multi Factor Authentication (MFA) to Endpoint Detection and Response (EDR), and email filtering protections to the robustness of your backups.

Make sure to review your cyber insurance policy and its related questionnaire. And ask whether you are doing everything you can to protect your firm and tailoring your actions to align with what your insurance provider has deemed as a best practice.

• NCSC Shut Down 2.7 Million Scams in 2021

The UK National Cyber Security Centre (NCSC) removed 2.7 million online scams last year, it was revealed this week, four times as many scams compared to 2020.

The announcement comes as the security agency shared the most recent data from its Active Cyber Defence initiative at the CYBERUK summit earlier in the week.

According to the NCSC, neutralised scams included fake celebrity endorsements and spoof extortion emails.

It has also been revealed that fraud campaigns used common themes, with NHS vaccines and vaccine passports being particularly popular.

Some cyber criminals even posed as NCSC CEO Lindy Cameron – victims received an email claiming the NCSC had prevented £5m of their money from being stolen, and were urged to supply personal information to retrieve the funds.

• Security Threats Targeting Remote Workers

Remote work offers great benefits, like reduced commute time, increased freedom, and more time to spend with loved ones. But there can be security downsides if sufficient controls are not in place to protect remote workers against the digital threats that come with working via unsecured connections.

Being on a home network lacks the layered network security of the company environment. Remote work itself is not new, but the dramatic shift to working from home over the past two years means there are more security-naive people who are not in the office.

Not all security threats are the fault of technology. Much of it also comes from human error.

Remote work greatly exacerbates human-activated risk, and people are working in more distracting environments where they may have to answer the door for deliveries or might multitask with household chores. That means mistakes are more likely to happen, like sending an email to the wrong recipient or falling for a malicious email attack.

Recent research by Egress found that 77% of IT leaders said they have seen an increase in security compromises since going remote two years ago.

• Password Reuse Is Rampant Among Employees in All Sectors

SpyCloud published an annual analysis of identity exposure among employees of Fortune 1000 companies in key sectors such as technology, finance, retail and telecommunications.

Drawing on a database of over 200 billion recaptured assets, researchers identified over 687 million exposed credentials and PII tied to Fortune 1000 employees, a 26% increase from last year’s analysis.

Analysis of this data showed a 64% password reuse rate, widespread use of easy-to-guess passwords, and a spike in malware-infected devices –– all sources of cyber risk for both employers and consumers who rely on businesses to safeguard their personal data. With remote work blurring the lines between work and personal device use, a larger attack surface compounds the risk of cyber attacks proliferating beyond compromised employee and consumer identities to penetrate corporate networks.

Black Arrow Cyber Threat Briefing 05 May 2022

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

• Cyber Scams Cost Victims $6.9b-Plus Worldwide in 2021

Cyber-scams cost victims around the globe at least $6.9 billion last year, according to the FBI's latest Internet Crime Report.

Since 2017, the bureau's Internet Crime Complaint Center (IC3) received an average of 552,000 complaints per year. This includes reports of extortion, identity theft, phishing, fraud, and a slew of other nefarious schemes that cost victims no less than $18.7 billion in losses over the five-year period.

Unsurprisingly, the volume of these crimes — and related costs — have grown every year; 2021 set records for the total number of complaints (847,376) as well as losses exceeding $6.9 billion, a jump from the $4.2 billion reported a year earlier.

As with earlier years, phishing attacks were by far the most commonly reported crimes, with 323,972 last year. A subset of this category, business email compromise (BEC), is proving very lucrative and cost victims almost $2.4 billion from 19,954 victims, according to the Feds.

BEC involves a cyber criminal compromising a legitimate email account, and then tricking a business or individual into transferring funds, sending employees' personal data, or unlocking cryptocurrency wallets. The fraudster then steals the cash, drains the crypto wallet and/or sells employees' identities and credentials on the dark web.

• Bad Actors Are Maximising Remote Everything

The rise of remote work and learning opened new opportunities for many people – as we’ve seen by the number of people who have moved to new places or adapted to “workcations.” Cyber criminals are taking advantage of the same opportunities – just in a different way. Evaluating the prevalence of malware variants by region reveals a sustained interest by cyber adversaries in maximising the remote work and learning attack vector.

As hybrid work and learning become embedded paradigms in our culture, there are fewer layers of protection between malware and would-be victims. And bad actors are gaining access to more tools to help them pull off their nefarious deeds – like exploit kits. At the same time, the attack surface has rapidly expanded and continues to do so.

That means enterprises must take a work-from-anywhere approach to their security. They need to deploy solutions capable of following, enabling and protecting users no matter where they are located. They need security on the endpoint (EDR) combined with zero trust network access (ZTNA) approaches.

• This Sneaky Hacking Group Hid Inside Networks For 18 Months Without Being Detected

A previously undisclosed cyber-espionage group is using clever techniques to breach corporate networks and steal information related to mergers, acquisitions and other large financial transactions – and they've been able to remain undetected by victims for periods of more than 18 months.

Detailed by cyber security researchers at Mandiant, who've named it UNC3524, the hacking operation has been active since at least December 2019 and uses a range of advanced methods to infiltrate and maintain persistence on compromised networks that set it apart from most other hacking groups. These methods include the ability to immediately re-infect environments after access is removed. It's currently unknown how initial access is achieved. 

One of the reasons UNC3524 is so successful at maintaining persistence on networks for such a long time is because it installs backdoors on applications and services that don't support security tools, such as anti-virus or endpoint protection.

https://www.zdnet.com/article/this-sneaky-hacking-group-hid-inside-networks-for-18-months-without-being-detected/

• FBI: Business Email Compromise: The $43 Billion Scam

According to the FBI, business email compromise (BEC) and email account compromise (EAC) losses have surpassed $43 billion globally. BEC/EAC is a sophisticated scam that targets both businesses and individuals who perform legitimate transfer-of-funds requests.

The BEC/EAC scam continues to grow and evolve, targeting small local businesses to larger corporations, and personal transactions. Between July 2019 and December 2021, there was a 65% increase in identified global exposed losses, meaning the dollar loss that includes both actual and attempted loss in United States dollars.

The following information was derived from filings with financial institutions between June 2016 and December 2021:

• Domestic and international incidents: 241,206

• Domestic and international exposed dollar loss: $43,312,749,946

The following BEC/EAC statistics were reported in victim complaints to the IC3 between October 2013 and December 2021:

• Total US victims: 116,401

• Total US exposed dollar loss: $14,762,978,290

• Total non-US victims: 5,260

• Total non-US exposed dollar loss: $1,277,131,099

• Disgruntled Employees Cashing in On Confidential Information Over Dark Web

Disgruntled employees are making hundreds of thousands of dollars by leaking confidential information over a new platform on the so-called dark web, cyber researchers have said.

Hidden in a part of the internet that is only accessible using special software, the Industrial Spy platform promises huge payouts to staff willing to hand over "dirty secrets" to competitors, according to experts at intelligence business Cyberint.

Industrial Spy currently has data on twelve companies from a range of industries available to people who sign up, Cyberint said.

The platform recently managed to sell two tranches of company data for $400,000 (£318,236) and $750,000 each.

An individual has advertised the platform to potential purchasers of the data on the dark web.

The post said: "With our information you could refuse partnership with an unscrupulous partner, reveal dirty secrets of your competitors and earn millions of dollars using insider information."

Cyber criminals have long approached employees individually and offered a bribe to release sensitive information such as internal data and passwords to access computer systems.

But this new platform allows employees to act on their own initiative to steal data and sell it online.

• Google Sees More APTs Using Ukraine War-Related Themes

Researchers at Google's Threat Analysis Group (TAG) say the number of advanced threat actors using Ukraine war-related themes in cyber attacks went up in April with a surge in malware attacks targeting critical infrastructure.

According to Google, known state-backed APT groups from China, Iran, North Korea, and Russia, along with various unattributed groups have been using war-related themes in phishing and malware distribution campaigns.

Looking at the cyber attacks that target Eastern Europe, however, a new Google report notes there hasn't been a significant change from the normal levels of activity, despite the increased adoption of lures related to the Ukraine war.

• Cryptocurrency Regulators Are Scrambling to Catch Up with Hackers Who Are Swiping Billions

Just four months in, 2022 has been a banner year for hackers, and fraudsters targeting the industry have swindled more than $1 billion from cryptocurrency investors, according to separate estimates by cryptocurrency analysis firm Immunefi.

The rise in fraud has put US regulators on the offensive. The US Securities and Exchange Commission, which has positioned itself as the industry’s main regulator and enforcer, announced on Tuesday that it was going to double its staff working to resources to combat the rise in fraud.

“Crypto markets have exploded in recent years, with retail investors bearing the brunt of abuses in this space. Meanwhile, cyber-related threats continue to pose existential risks to our financial markets and participants,” Gurbir Grewal, director of the SEC’s Division of Enforcement said in a statement. “The bolstered Crypto Assets and Cyber Unit will be at the forefront of protecting investors and ensuring fair and orderly markets in the face of these critical challenges.”

• Tackling the Threats Posed by Shadow IT

While remote technologies have allowed businesses to shift their workforces online, this flexibility has created a swathe of challenges for IT teams who must provide a robust security framework for their organisation – encompassing all the personnel and devices within their remit. In addition to the ever-increasing number of personal devices, corporate devices and programs, more and more applications are moving to the cloud as workloads become increasingly distributed across public clouds and software-as-a-service (SaaS).

This means IT teams are even harder pressed to secure and manage the complex environments they operate in. The unsanctioned use of corporate IT systems, devices, and software – known as shadow IT – has increased significantly during the shift to remote work, and recent research found almost one in seven (68%) are concerned about information security because of employees following shadow IT practices.

Shadow IT can allow hackers to steal employee and customer identities, company intellectual property, and cause companies to fail compliance audits. It can also open the door to enterprises accidentally breaking laws and exposes organisations to data exfiltration, malware, and phishing.

• Hackers Used the Log4j Flaw to Gain Access Before Moving Across a Company's Network, Say Security Researchers

State-backed hacking groups are some of the most advanced cyber attack operations in the world - but criminals don't need to rely on them if they can exploit unpatched cyber security flaws.

A North Korean hacking and cyber espionage operation breached the network of an engineering firm linked to military and energy organisations by exploiting a cyber security vulnerability in Log4j.

First detailed in December, the vulnerability (CVE-2021-44228) allows attackers to remotely execute code and gain access to systems that use Log4j, a widely used Java logging library.

The ubiquitous nature of Log4j meant cyber security agencies urged organisations globally to apply security updates as quickly as possible, but months on from disclosure, many are still vulnerable to the flaw.

According to cyber security researchers at Symantec, one of those companies that was still vulnerable was an undisclosed engineering firm that works in the energy and military sectors. That vulnerability resulted in the company being breached when attackers exploited the gap on a public-facing VMware View server in February this year. From there, attackers were able to move around the network and compromise at least 18 computers.

• New Hacker Group Pursuing Corporate Employees Focused on Mergers and Acquisitions

[Explanatory note from Black Arrow: When a group of cyber attackers is identified by the cyber security community, it is given a code name usually composed of letters and digits. These groups are also sometimes referred to as APTs., or Advanced Persistent Threats, because the groups are highly skilled and are persistent in their attacks; they are often supported by their state government].

A newly discovered suspected espionage threat actor has been targeting employees focusing on mergers and acquisitions as well as large corporate transactions to facilitate bulk email collection from victim environments.

Mandiant is tracking the activity cluster under the uncategorised moniker UNC3524, citing a lack of evidence linking it to an existing group. However, some of the intrusions are said to mirror techniques used by different Russia-based hacking crews like APT28 and APT29.

"The high level of operational security, low malware footprint, adept evasive skills, and a large Internet of Things (IoT) device botnet set this group apart and emphasise the 'advanced' in Advanced Persistent Threat," the threat intelligence firm said in a report.

The initial access route is unknown but upon gaining a foothold, attack chains involving UNC3524 culminate in the deployment of a novel backdoor called QUIETEXIT for persistent remote access for as long as 18 months without getting detected in some cases.
