Black Arrow Cyber Advisory 09 March 2023 – Security Flaws in TPM 2.0 Pose Significant Risk

Black Arrow Cyber Advisory 08 March 2023 – Security Flaws in TPM 2.0 Pose Significant Risk

Executive Summary

Security Researchers at Quarkslab have identified two critical vulnerabilities (CVE-2023-1017 and CVE-2023-1018) in The Trusted Platform Module (TPM) firmware; TPMs are used by most modern PCs to make them resistant to tampering and the vulnerabilities could affect billions of devices.

What’s the risk to my business?

Successful exploitation of the vulnerabilities could lead to local information disclosure, including the ability for attackers to make the TPM unavailable leading to denial of service, read sensitive data or escalate privileges. In some cases, an attacker can overwrite protected data in the TPM and go undetected. To be able to exploit the vulnerabilities the attacker would require access to a TPM-command interface to send maliciously crafted-commands to a vulnerable TPM.

What can I do?

The Trusted Computing Group (TCG) have released an updated version of their TPM2.0 library specification: TPM 2.0 library Specifications v1.59 Errata Version 1.4. Once this update has been incorporated within Operating System and Original Equipment Manufacturer (OEM) firmware, it is recommended this updated version is installed. For the meantime, remote attestation may help identify it any changes have been made to the TPM.

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

  • It’s Time to Evaluate Your Security Education Plan with the Rise in Social Engineering Attacks

Security provider Purplesec found 98% of attacks in 2022 involved an element of social engineering. Social engineering attacks can take many forms including phishing, smishing, vishing and quishing and it’s vital to educate your organisation on how to best prepare for these. Education plans should focusing on educating all levels of users, including those at the top. These plans should also be tested to allow organisations to assess where they are at and identify where they can improve.

  • Mobile Users are More Susceptible to Phishing Attacks

A report conducted by mobile security provider Lookout focused on the impact of mobile phishing. Some of the key findings from the report included that more than 50% of personal devices were exposed to a mobile phishing attack every quarter, the percentage of users falling for multiple mobile phishing links increasing and an increased targeting of highly regulated industries such as insurance, banking and financial services. It is likely that this has resulted from the increase in relaxed bring your own device (BYOD) policies.

  • Phishing as a Service Stimulates Cyber Crime

Phishing attacks are at an all-time high and the usage of Phishing as a Service (PaaS) opens this attack technique to virtually anyone. The sale of “phishing kits” and usage of artificial intelligence has further increased the availability of this attack technique. In response, organisations should look to improve their email security, cloud security and education programs for employees.

https://www.trendmicro.com/en_us/ciso/23/c/phishing-as-a-service-phaas.html

  • Attacker Breakout Time Drops to Just 84 Minutes

The average time it takes for a threat actor to move laterally from a compromised host within an organisation dropped 14% between 2012 and 2022 down to 84 minutes, according to a report by security provider Crowdstrike. With the reduction in time it takes a threat actor to move across systems, organisations have even less time to enact their incident response plans and contain breaches effectively, putting further pressure on the incident response team. By responding quickly, organisations can minimise the cost and damage of a breach. The report from Crowdstrike found that organisations were facing increasing difficulty in detecting suspicious activity as attackers are choosing to use valid organisation credentials rather than malware, to gain access to an organisation’s systems.

https://www.infosecurity-magazine.com/news/attacker-breakout-time-drops-just/

  • Attackers are Developing and Deploying Exploits Faster Than Ever

A report from security provider Rapid7 found that over 56% of vulnerabilities were exploited within seven days of public disclosure. Worryingly, the median time for exploitation in 2022 was just one day. The finding from the report highlights the need for organisations to not only conduct threat intelligence to be aware of vulnerabilities but to also look to employ patches where possible in a timely manner.

https://www.helpnetsecurity.com/2023/03/03/attackers-developing-deploying-exploits/

  • Old Vulnerabilities are Haunting Organisations and Aiding Attackers

Known vulnerabilities, vulnerabilities for which patches have already been made available, are one of the primary attack vectors for threat actors. Vulnerability management vendor Tenable found that the top exploited vulnerabilities were originally disclosed as far back as 2017 and organisations that had not applied these patches were at increased risks of attack.

https://www.helpnetsecurity.com/2023/03/03/known-exploitable-vulnerabilities/

  • Scams Drive Nearly $9bn Fraud Surge in 2022

Americans lost $8.8 billion to fraud last year, with imposter scams responsible for $2.8 billion of that amount, according to the Federal Trade Commission (FTC). Losses to business imposters were particularly damaging, climbing to $660 million from the previous year. Interestingly, the FTC found that younger people reported losing money to fraud the most often.

https://www.infosecurity-magazine.com/news/investment-scams-drive-9bn-in/

  • Economic Pressure are Increasing Cyber Security Risks and a Recession Would Only Further This

The World Economic Forum’s recent report found that 93% of cyber security leaders and 86% of business leaders think it is moderately or very likely that global geopolitical instability will lead to a catastrophic cyber event in the next two years. Reinforcing this, a report from (ISC)² found that 80% of business executives believe a weakening economy will increase cyber threats and a recession will only amplify this.

https://www.csoonline.com/article/3689008/economic-pressures-are-increasing-cybersecurity-risks-a-recession-would-amp-them-up-more.html

  • Cyber Security in this Era of Polycrisis

A year since Russia invaded Ukraine, the geopolitical context is increasingly tense and volatile. The world faces several major crises in what has been coined a 'polycrisis,' a cluster of global shocks with compounding effects. This, along with increasing geopolitical tensions causes a rise in risk from cyber attacks. In fact, the European Union Agency for Cyber Security (ENISA) recently issued an alert regarding actors conducting malicious cyber activities against businesses and governments in the European Union and findings from Google show a 300% increase in state-sponsored cyber attacks targeting users in NATO countries.

  • Russian Ransomware Projects Rebranded to Avoid Western Sanctions

Research provider TRM labs found that some major Russian-linked ransomware crime gangs have rebranded their activities in 2022 to avoid sanctions. To strengthen their anonymity, two major ransomware crime gangs LockBit and Conti restructured their activities. Conti is reported to have restructured into three smaller groups named Black Besta, BlackByte, Karakurt. LockBit on the other hand launched LockBit 3.0, which is focused on monetary gain. Additionally, the report found that Russian-speaking darknet markets had amassed over $130 million in sales.

  • Ransomware Attacks Ravaged Big Names in February

Despite the apparent slight drop in ransomware activity last month, several high profile targets of various industries were hit; this ranges from the likes of the US Marshal Service, retailer WH Smith, satellite provider Dish and many more. These attacks reinforce the concept that any organisation can be a victim, regardless of industry.

https://www.techtarget.com/searchsecurity/news/365532056/Ransomware-attacks-ravaged-big-names-in-February

  • Firms Who Pay Ransoms Subsidise New Attacks

A report from security provider Trend Micro found that whilst only a relatively small number of ransomware victims pay their extorters, those that do pay are effectively funding 6-10 new attacks. The report also found that attackers are aware of which industries and countries pay ransoms more often, so organisations belonging to those industries and countries may find themselves an even more attractive target.

https://www.infosecurity-magazine.com/news/firms-pay-ransom-subsidise-10/

  • How the Ukraine War Opened a Fault Line in Cyber Crime

A report from threat intelligence provider Recorded Future has highlighted the impact that the Russian invasion of Ukraine has had on cyber. Recorded Future explain how a number of threat actor groups fled during the war and in addition to differing political views between groups, there has been a disruption to the cyber environment. In fact, Recorded Future found that Russian-language dark web marketplaces have taken a major hit and the prediction is that the epicentre of cyber crime may shift to English-speaking dark web forums, shops and marketplaces.

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

Ransomware Volumes Hit Record Highs As 2021 Wears On

Ransomware has seen a significant uptick so far in 2021, with global attack volume increasing by 151 percent for the first six months of the year as compared with the year-ago half. Meanwhile, the FBI has warned that there are now 100 different strains circulating around the world. From a hard-number perspective, the ransomware scourge hit a staggering 304.7 million attempted attacks. To put that in perspective, the firm logged 304.6 million ransomware attempts for the entirety of 2020.

Ransomware Gangs Recruiting Insiders To Breach Corporate Networks

The LockBit 2.0 ransomware gang is actively recruiting corporate insiders to help them breach and encrypt networks. In return, the insider is promised million-dollar payouts. Many ransomware gangs operate as a Ransomware-as-a-Service, which consists of a core group of developers, who maintain the ransomware and payment sites, and recruited affiliates who breach victims' networks and encrypt devices. Any ransom payments that victims make are then split between the core group and the affiliate, with the affiliate usually receiving 70-80% of the total amount. However, in many cases, the affiliates purchase access to networks from other third-party pentesters rather than breaching the company themselves. With LockBit 2.0, the ransomware gang is trying to remove the middleman and instead recruit insiders to provide them access to a corporate network.

More Than 12,500 Vulnerabilities Disclosed In First Half Of 2021

Two new reports were released, covering data breaches and vulnerabilities in the first half of 2021, finding that there was a decline in the overall number of reported breaches but an increase in the number of vulnerabilities disclosed.  The company's data breach report found that there were 1,767 publicly reported breaches in the first six months of 2021, a 24% decline compared to the same period last year. The number of reported breaches grew in the US by 1.5% while 18.8 billion records were exposed year to date, a 32% decline compared to the 27.8 billion records leaked in the first half of 2020.

New DNS Vulnerability Allows 'Nation-State Level Spying' On Companies

Security researchers found a new class of DNS vulnerabilities impacting major DNS-as-a-Service (DNSaaS) providers that could allow attackers to access sensitive information from corporate networks.

DNSaaS providers (also known as managed DNS providers) provide DNS renting services to other organisations that do not want to manage and secure yet another network asset on their own.

These DNS flaws provide threat actors with nation-state intelligence harvesting capabilities with a simple domain registration.

Constant Review Of Third Party Security Critical As Ransomware Threat Climbs

Enterprises typically would give their third-party suppliers "the keys to their castle" after carrying out the usual checks on the vendor's track history and systems, according to a New York-based Forrester analyst who focuses on security and risk. They believed they had done their due diligence before establishing a relationship with the supplier, but they failed to understand that they should be conducting reviews on a regular basis, especially with their critical systems suppliers. Third-party suppliers should have the ability to deal with irregular activities in their systems and the appropriate security architecture in place to prevent any downstream effects, he added.

Kaseya Ransomware Attack Sets Off Race To Hack Service Providers

A ransomware attack in July that paralyzed as many as 1,500 organisations by compromising tech-management software from a company called Kaseya has set off a race among criminals looking for similar vulnerabilities, cyber security experts said. An affiliate of a top Russian-speaking ransomware gang known as REvil used two gaping flaws in software from Florida-based Kaseya to break into about 50 managed services providers (MSPs) that used its products, investigators said. Now that criminals see how powerful MSP attacks can be, "they are already busy, they have already moved on and we don’t know where," said head of the non-profit Dutch Institute for Vulnerability Disclosure, which warned Kaseya of the weaknesses before the attack.

‘It’s Quite Feasible To Start A War’: Just How Dangerous Are Ransomware Hackers?

Secretive gangs are hacking the computers of governments, firms, even hospitals, and demanding huge sums. But if we pay these ransoms, are we creating a ticking time bomb? They have the sort of names that only teenage boys or aspiring Bond villains would dream up (REvil, Grief, Wizard Spider, Ragnar), they base themselves in countries that do not cooperate with international law enforcement and they don’t care whether they attack a hospital or a multinational corporation. Ransomware gangs are suddenly everywhere, seemingly unstoppable – and very successful.

Joint UK/US Advisory Detailing Top 30 Vulnerabilities Include Plenty Of Usual Suspects

A joint advisory from law enforcement agencies in the US, UK, and Australia this week tallied the 30 most-frequently exploited vulnerabilities. Perhaps not surprisingly, the list includes a preponderance of flaws that were disclosed years ago; everything on the list has a patch available for whoever wants to install it. But as we've written about time and again, many companies are slow to push updates through for all kinds of reasons, whether it's a matter of resources, know-how, or an unwillingness to accommodate the downtime often necessary for a software refresh. Given how many of these vulnerabilities can cause remote code execution—you don't want this—hopefully they'll start to make patching more of a priority.

Average Total Cost Of A Data Breach Increased By Nearly 10% Year Over Year

Based on in-depth analysis of real-world data breaches experienced by over 500 organisations, the global study suggests that security incidents became more costly and harder to contain due to drastic operational shifts during the pandemic, with costs rising 10% compared to the prior year. Businesses were forced to quickly adapt their technology approaches last year, with many companies encouraging or requiring employees to work from home, and 60% of organisations moving further into cloud-based activities during the pandemic. The new findings suggest that security may have lagged behind these rapid IT changes, hindering organizations’ ability to respond to data breaches.

65% Of All DDoS Attacks Target US And UK

Distributed denial of service (DDoS) attacks are common for cyber criminals who want to disrupt online-dependent businesses. According to the data analysed by a VPN team, 65% of all distributed denial of service (DDoS) attacks are directed at the US or UK. Computers and the internet industry are the favourite among cyber criminals. The United States was a target for 35% of all DDoS attacks in June 2021. Cyber criminals launched DDoS attacks against Amazon Web Services, Google, and other prominent US-based companies in the past. The United Kingdom comes second as it fell victim to 29% of all DDoS attacks. As the UK has many huge businesses, they often are targeted by hackers for valuable data or even a ransom. China was threatened by 18% of all DDoS attacks in June 2021. Assaults from and to China happen primarily due to political reasons, to interrupt some government agency.
