Top Cyber Stories of the Last Week

  • Cyber Attacks Set to Become ‘Uninsurable’, Says Zurich Chief

The chief executive of one of Europe’s biggest insurance companies has warned that cyber attacks, rather than natural catastrophes, will become “uninsurable” as the disruption from hacks continues to grow.

Insurance executives have been increasingly vocal in recent years about systemic risks, such as pandemics and climate change, that test the sector’s ability to provide coverage. For the second year in a row, natural catastrophe-related claims are expected to top $100bn. 

But Mario Greco, chief executive at insurer Zurich, told the Financial Times that cyber was the risk to watch. “What will become uninsurable is going to be cyber,” he said. “What if someone takes control of vital parts of our infrastructure, the consequences of that?” Recent attacks that have disrupted hospitals, shut down pipelines and targeted government departments have all fed concern about this expanding risk among industry executives. Focusing on the privacy risk to individuals was missing the bigger picture, Greco added: “First off, there must be a perception that this is not just data . . . this is about civilisation. These people can severely disrupt our lives.” 

Spiralling cyber losses in recent years have prompted emergency measures by the sector’s underwriters to limit their exposure. As well as pushing up prices, some insurers have responded by tweaking policies so clients retain more losses. There are exemptions written into policies for certain types of attacks. In 2019, Zurich initially denied a $100mn claim from food company Mondelez, arising from the NotPetya attack, on the basis that the policy excluded a “warlike action”. The two sides later settled. In September, Lloyd’s of London defended a move to limit systemic risk from cyber attacks by requesting that insurance policies written in the market have an exemption for state-backed attacks.

Your Business Should Compensate for Modern Ransomware Capabilities Right Now

The “if, not when” mentality surrounding ransomware may be the biggest modern threat to business longevity. Companies of all sizes and across all industries are increasingly common targets for ransomware attacks, and we know that 94% of organisations experienced a cyber security incident last year alone. Yet, many enterprises continue to operate with decades-old security protocols that are unequipped to combat modern ransomware. Leaders have prioritised improving physical security measures in light of the pandemic — so why haven’t ransomware protections improved?

Maybe it’s the mistaken notion that ransomware attacks are declining. In reality, Q1 of 2022 saw a 200% YoY increase in ransomware incidents. Meanwhile, the rise in Ransomware as a Service (RaaS) offerings suggests that cyber threats have become a commodity for bad actors.

The RaaS market presents a new and troubling trend for business leaders and IT professionals. With RaaS — a subscription ransomware model that allows affiliates to deploy malware for a fee — the barrier to entry for hackers is lower than ever. The relatively unskilled nature of RaaS hackers may explain why the average ransomware downtime has plummeted to just 3.85 days (compared to an average attack duration of over two months in 2019).

While the decrease in attack duration is promising, the rise of RaaS still suggests an inconvenient truth for business leaders: All organisations are at risk. And in time, all organisations will become a target, which is why it’s time for IT and business leaders to implement tough cyber security protocols.

  • Reported Phishing Attacks Have Quintupled

In the third quarter of 2022, the international Anti-Phishing Working Group (APWG) consortium observed 1,270,883 total phishing attacks; the worst quarter for phishing that APWG has ever observed. The total for August 2022 was 430,141 phishing sites, the highest monthly total ever reported to APWG.

Over recent years, reported phishing attacks submitted to APWG have more than quintupled since the first quarter of 2020, when APWG observed 230,554 attacks. The rise in Q3 2022 was attributable, in part, to increasing numbers of attacks reported against several specific targeted brands. These target companies and their customers suffered from large numbers of attacks from persistent phishers.

Threat researchers at the cyber security solution provider Fortra noted a 488 percent increase in response-based email attacks in Q3 2022 compared to the prior quarter. While every subtype of these attacks increased compared to Q2, the largest increase was in Advance Fee Fraud schemes, which rose by a staggering 1,074 percent.

In the third quarter of 2022, APWG founding member OpSec Security found that phishing attacks against the financial sector, which includes banks, remained the largest set of attacks, accounting for 23.2 percent of all phishing. Attacks against webmail and software-as-a-service (SaaS) providers remained prevalent as well. Phishing against social media services fell to 11 percent of the total, down from 15.3 percent.

Phishing against cryptocurrency targets — such as cryptocurrency exchanges and wallet providers — fell from 4.5 percent of all phishing attacks in Q2 2022 to 2 percent in Q3. This mirrored the fall in value of many cryptocurrencies since mid-year.

  • Ransomware, DDoS See Major Upsurge Led by Upstart Hacker Group

Cyber threat actors Cuba and Royal are driving a 41% boom in ransomware and other attacks hitting industry and consumer goods and services.

According to the Global Threat Intelligence team of information assurance firm NCC Group, November saw a 41% increase in ransomware attacks from 188 incidents to 265. In its most recent Monthly Threat Pulse, the group reported that the month was the most active for ransomware attacks since April this year.

Key takeaways from the study:

  • Ransomware attacks rose by 41% in November.

  • Threat group Royal (16%) was the most active, replacing LockBit as the worst offender for the first time since September 2021.

  • Industrials (32%) and consumer cyclicals (44%) remain the top two most targeted sectors, but technology experienced a large 75% increase over the last month.

  • Regional data remains consistent with last month — North America (45%), Europe (25%) and Asia (14%)

  • DDoS attacks continue to increase.

Recent examples in the services sector include the Play ransomware group’s claimed attack of the German H-Hotels chain, resulting in communications outages. This attack reportedly uses a vulnerability in Microsoft Exchange called ProxyNotShell, which as the name implies, has similarities to the ProxyShell zero-day vulnerability revealed in 2021.

Also, back on the scene is the TrueBot malware downloader (a.k.a., the silence.downloader), which is showing up in an increasing number of devices. TrueBot Windows malware, designed by a Russian-speaking hacking group identified as Silence, has resurfaced bearing Ransom.Clop, which first appeared in 2019. Clop ransomware encrypts systems and exfiltrates data with the threat that if no ransom is forthcoming, the data will show up on a leak site.

  • Videoconferencing Worries Grow, With SMBs in Cyber Attack Crosshairs

Securing videoconferencing solutions is just one of many IT security challenges small businesses are facing, often with limited financial and human resources.

It's no secret that the acceleration of work-from-home and distributed workforce trends — infamously spurred on by the pandemic — has occurred in tandem with the rise of video communications and collaboration platforms, led by Zoom, Microsoft, and Cisco.

But given that videoconferencing now plays a critical role in how businesses interact with their employees, customers, clients, vendors, and others, these platforms carry significant potential security risks, researchers say.

Organisations use videoconferencing to discuss M&A, legal, military, healthcare, intellectual property and other topics, and even corporate strategies. A loss of that data could be catastrophic for a company, its employees, its clients, and its customers.

However, a recent report on videoconferencing security showed that 93% of IT professionals surveyed acknowledged security vulnerabilities and gaping risks in their videoconferencing solutions.

Among the most relevant risks is the lack of controlled access to conversations that could result in disruption, sabotage, compromise, or exposure of sensitive information, while use of nonsecure, outdated, or unpatched videoconferencing applications can expose security flaws.

The risks include the potential for interruptions, unauthorised access, and perhaps most concerning, the opportunity for a bad actor to acquire sensitive information.

  • Will the Crypto Crash Impact Cyber Security in 2023? Maybe.

With the implosion of the FTX exchange putting a punctuation mark on the cryptocurrency crash of 2022, one of the natural questions for those in the cyber security world is, how will this rapid decline of cryptocurrency valuations change the cyber crime economy?

Throughout the most recent crypto boom, and even before then, cyber criminals have used and abused cryptocurrency to build up their empires. The cryptocurrency market provides the extortionary medium for ransomware; it's a hotbed of scams against consumers to steal their wallets and accounts. Traditionally, it's provided a ton of anonymous cover for money laundering on the back end of a range of cyber criminal enterprises.

Even so, according to cyber security experts and intelligence analysts, while there certainly have been some shifts in trends and tactics that they believe are loosely tied to the crypto crash, the jury's still out on long-term impacts.

Regardless of crypto values, cyber criminals this year have definitely become more sophisticated in how they use cryptocurrencies to monetise their attacks including the use by some ransomware groups taking advantage of yield farming within decentralised finance (DeFi), as an example.

The concept of yield farming is the same as lending money, with a contract in place that clearly shows how much interest will need to be paid. The advantage for ransomware groups is that the 'interest' will be legitimate proceeds, so there will be no need to launder or hide it.

Threat actors are increasingly turning toward 'stablecoins,' which are usually tied to fiat currencies or gold to stem their volatility. In many ways, the downturn in crypto values has increased the risk appetite of cyber criminals and is spurring them into more investment fraud and cryptocurrency scams.

  • The Worst Hacks of 2022

The year was marked by sinister new twists on cyber security classics, including phishing, breaches, and ransomware attacks.

With the pandemic evolving into an amorphous new phase and political polarisation on the rise around the world, 2022 was an uneasy and often perplexing year in digital security. And while hackers frequently leaned on old chestnuts like phishing and ransomware attacks, they still found vicious new variations to subvert defences.

Technology magazine Wired looked back on the year's worst breaches, leaks, ransomware attacks, state-sponsored hacking campaigns, and digital takeovers. If the first years of the 2020s are any indication, the digital security field in 2023 will be more bizarre and unpredictable than ever. Stay alert, and stay safe out there.

Russia Hacking Ukraine

For years, Russia has pummelled Ukraine with brutal digital attacks causing blackouts, stealing and destroying data, meddling in elections, and releasing destructive malware to ravage the country's networks. Since invading Ukraine in February, though, times have changed for some of Russia's most prominent and most dangerous military hackers. Shrewd long-term campaigns and grimly ingenious hacks have largely given way to a stricter and more regimented clip of quick intrusions into Ukrainian institutions, reconnaissance, and widespread destruction on the network—and then repeated access over and over again, whether through a new breach or by maintaining the old access.

Twilio and the 0ktapus Phishing Spree

Over the summer, a group of researchers dubbed 0ktapus went on a massive phishing bender, compromising nearly 10,000 accounts within more than 130 organisations. The majority of the victim institutions were US-based, but there were dozens in other countries as well.

Ransomware Still Hitting the Most Vulnerable Targets

In recent years, countries around the world and the cyber security industry have increasingly focused on countering ransomware attacks. While there has been some progress on deterrence, ransomware gangs were still on a rampage in 2022 and continued to target vulnerable and vital social institutions, including health care providers and schools. The Russian-speaking group Vice Society, for example, has long specialised in targeting both categories, and it focused its attacks on the education sector this year.

The Lapsus$ Rampage Continues

The digital extortion gang Lapsus$ was on an intense hacking spree at the beginning of 2022, stealing source code and other sensitive information from companies like Nvidia, Samsung, Ubisoft, and Microsoft and then leaking samples as part of apparent extortion attempts. Lapsus$ has a sinister talent for phishing, and in March, it compromised a contractor with access to the ubiquitous authentication service Okta.

LastPass

The beleaguered password manager giant LastPass, which has repeatedly dealt with data breaches and security incidents over the years, said at the end of December that a breach of its cloud storage in August led to a further incident in which hackers targeted a LastPass employee to compromise credentials and cloud storage keys.

Vanuatu

At the beginning of November, Vanuatu, an island nation in the Pacific, was hit by a cyber attack that took down virtually all of the government's digital networks. Agencies had to move to conducting their work on paper because emergency systems, medical records, vehicle registrations, driver's license databases, and tax systems were all down.

Honourable Mention: Twitter-Related Bedlam

Twitter has been in chaos mode for months following Elon Musk's acquisition of the company earlier this year. Amidst the tumult, reports surfaced in July and then again in November of a trove of 5.4 million Twitter users' data that has been circulating on criminal forums since at least July, if not earlier. The data was stolen by exploiting a vulnerability in a Twitter application programming interface, or API.

  • Geopolitical Tensions Expected to Further Impact Cyber Security in 2023

Geopolitics will continue to have an impact on cyber security and the security posture of organisations long into 2023.

The impact of global conflicts on cyber security was thrust into the spotlight when Russia made moves to invade Ukraine in February 2022. Ukraine’s Western allies were quick to recognise that with this came the threat of Russian-backed cyber-attacks against critical national infrastructure (CNI), especially in retaliation to hefty sanctions. While this may not have materialised in the way many expected, geopolitics is still front of mind for many cyber security experts looking to 2023.

Russia has always been among a handful of states recognised for their cyber prowess and being the source of many cyber criminal gangs. As previously mentioned, we have failed to see a significant cyber-attack, at least one comparable to the Colonial Pipeline incident, in 2022. However the cyber security services provider, e2e-assure, warned: “We have underestimated Russia’s cyber capability. There is a wide view that Russian cyber activity leading up to and during their invasion of Ukraine indicated that they aren’t the cyber power we once thought. Patterns and evidence will emerge in 2023 that shows this wasn’t the case, instead Russia was directing its cyber efforts elsewhere, with non-military goals (financial and political).”

NordVPN, the virtual private network (VPN) provider, warns that the cyber-war is only just starting: “With China’s leader securing his third term and Russia’s war in Ukraine, many experts predict an increase in state-sponsored cyber-attacks. China may increase cyber-attacks on Taiwan, Hong Kong, and other countries opposing the regime. Meanwhile, Russia is predicted to sponsor attacks on countries supporting Ukraine.”

We are used to seeing cyber-attacks that encrypt data and ask for ransom, but it is likely in this era of nation-state sponsored attacks we could experience attacks for the sake of disruption.

  • Fraudsters’ Working Patterns Have Changed in Recent Years

Less sophisticated fraud — in which doctored identity documents are readily spotted — has jumped 37% in 2022, according to the identify verfication provider Onfido. Fraudsters can scale these attacks on an organisation’s systems around the clock.

It is estimated that the current global financial cost of fraud is $5.38 trillion (£4.37 trillion), which is 6.4% of the world’s GDP. With most fraud now happening online (80% of reported fraud is cyber-enabled), Onfido’s Identity Fraud Report uncovers patterns of fraudster behaviour, attack techniques, and emerging tactics.

Over the last four years, fraudsters’ working patterns have dramatically changed. In 2019, attacks mirrored a typical working week, peaking Monday to Friday and dropping off during the weekends. Yet over the last three years, fraudulent activity started to shift so that levels of fraud span every day of the week.

In 2022, fraud levels were consistent across 24 hours, seven days a week. With technology, fraudsters are more connected across the globe and are able to traverse regions and time zones, and can easily take advantage of businesses’ closed hours when staff are likely offline. This hyperconnectivity means there are no more ‘business hours’ for fraudsters and sophisticated fraud rings — they will scam and defraud 24/7.

“As criminals look to take advantage of digitisation processes, they’re able to commit financial crimes with increasing efficiency and sophistication, to the extent that financial crime and cyber crime are now invariably linked,” said Interpol. “A significant amount of financial fraud takes place through digital technologies, and the pandemic has only hastened the emergence of digital money laundering tools and other cyber-enabled financial crimes.”

  • Hacktivism is Back and Messier Than Ever

Throughout 2022, geopolitics has given rise to a new wave of politically motivated attacks with an undercurrent of state-sponsored meddling.

During its brutal war in Ukraine, Russian troops have burnt cities to the ground, raped and tortured civilians, and committed scores of potential war crimes. On November 23, lawmakers across Europe overwhelmingly labelled Russia a “state sponsor” of terrorism and called for ties with the country to be reduced further. The response to the declaration was instant. The European Parliament’s website was knocked offline by a DDoS attack.

The unsophisticated attack—which involves flooding a website with traffic to make it inaccessible—disrupted the Parliament’s website offline for several hours. Pro-Russian hacktivist group Killnet claimed responsibility for the attack. The hacktivist group has targeted hundreds of organisations around the world this year, having some limited small-scale successes knocking websites offline for short periods of time. It’s been one player in a bigger hacktivism surge.

Following years of sporadic hacktivist activity, 2022 has seen the re-emergence of hacktivism on a large scale. Russia’s full-scale invasion of Ukraine spawned scores of hacktivist groups on both sides of the conflict, while in Iran and Israel, so-called hacktivist groups are launching increasingly destructive attacks. This new wave of hacktivism, which varies between groups and countries, comes with new tactics and approaches and, increasingly, is blurring lines between hacktivism and government-sponsored attacks.
