Top Cyber Stories of the Last Week
Cyber Attacks On The Rise For Businesses, Pushing Many To The Brink
The proportion of businesses targeted by cyber criminals in the past year increased from 38% to 43%, with over a quarter of those targeted (28%) experiencing five attacks or more. Those attacks are pushing many firms to the brink, with one in six businesses attacked (17%) saying the financial impact materially threatened the company’s future. On a more positive note, the report shows firms are responding to the cyber challenge: mean spending per business on cyber security has more than doubled in the last two years.

MI5 Warns Of Spies Using Linkedin To Trick Staff Into Spilling Secrets
At least 10,000 UK nationals have been approached by fake profiles linked to hostile states, on the professional social network LinkedIn, over the past five years, according to MI5. It warned users who had accepted such connection requests might have then been lured into sharing secrets. A campaign has been launched to educate government workers about the threat. The 10,000-plus figure includes staff in virtually every government departments as well as key industries, who might be offered speaking or business and travel opportunities that could lead to attempts to recruit them to provide confidential information.

SonicWall Warns Customers To Patch 3 Zero-Days Exploited In The Wild
Security hardware manufacturer SonicWall is urging customers to patch a set of three zero-day vulnerabilities affecting both its on-premises and hosted Email Security products. "In at least one known case, these vulnerabilities have been observed to be exploited 'in the wild,'" SonicWall said in a security advisory published earlier today. The company said it is "imperative" that organisations using its Email Security hardware appliances, virtual appliances, or software installations on Microsoft Windows Server machines immediately upgrade to a patched version.
The FBI Removed Hacker Backdoors From Vulnerable Microsoft Exchange Servers. Not Everyone Likes The Idea
The FBI had worked to remove malicious web shells from hundreds of computers in the United States that were running vulnerable versions of Microsoft Exchange Server. While the move will have helped keep many organisations secure, it has also raised questions about the direction of cyber security. Earlier this year, four zero-day vulnerabilities in Microsoft Exchange Server, which were being actively exploited by a nation-state-backed hacking operation, were uncovered. Microsoft released a critical security update to protect Exchange Server customers from cyber attacks exploiting the vulnerabilities in March, but a significant number of organisations have yet to apply the security patch.
Pulse Secure VPN Zero-Day Used To Hack Defense Firms, Govt Organisations
A zero-day authentication bypass vulnerability in the Pulse Connect Secure (PCS) SSL VPN appliance actively exploited in attacks against worldwide organisations and focused on US Defence Industrial base networks. As a workaround, the vulnerability can be mitigated on some gateways by disabling Windows File Share Browser and Pulse Secure Collaboration features using instructions available in the security advisory published earlier today.
SolarWinds Hack Could Cost Cyber Insurance Firms $90 Million
Cyber insurance vendors are expected to spend $90 million on incident response and forensic services for clients who were compromised by the SolarWinds hackers. “Although the SolarWinds attack is a cyber catastrophe from a national security perspective, insurers may have narrowly avoided a catastrophic financial incident to their businesses,” The Russian hackers behind the SolarWinds attack appear to have avoided large scale exploitation of victims, instead opting to maintain access and collect sensitive data. But if the SolarWinds hackers had been focused on interrupting business and destroying networks, the campaign could have been catastrophic for insurers.

Mount Locker Ransomware Aggressively Changes Up Tactics
The Mount Locker ransomware has shaken things up in recent campaigns with more sophisticated scripting and anti-prevention features, according to researchers. And, the change in tactics appears to coincide with a rebranding for the malware into “AstroLocker.” According to researchers, Mount Locker has been a swiftly moving threat. Having just hit the ransomware-as-a-service scene in the second half of 2020, the group released a major update in November that broadened its targeting capabilities (including searching for file extensions utilized by TurboTax tax-return software to encrypt). It also added improved detection evasion. Attacks have continued to escalate, and now, another major update signals “an aggressive shift in Mount Locker’s tactics,”.

QR Codes Offer Easy Cyber Attack Avenues as Usage Spikes
The use of mobile quick-response (QR) codes in daily life, for both work and personal use, continues to rise – and yet, most people are not aware that these handy mobile shortcuts can open them up to savvy cyber attacks. A survey of 4,157 consumers across China, France, Germany, Japan, the U.K. and the U.S. It found that 57 percent of respondents have increased their QR code usage since mid-March 2020, mainly because of the need for touchless transactions in the wake of COVID-19. In all, three-quarters of respondents (77 percent) said they have scanned a QR code before, with 43 percent having scanned a QR code in the past week.

Google Alerts Continues To Be A Hotbed Of Scams And Malware
Google Alerts continues to be a hotbed of scams and malware that threat actors are increasingly abusing to promote malicious websites. While Google Alerts has been abused for a long time, a significant increase in activity over the past couple of weeks. People use Google Alerts to monitor for various terms related to cyber attacks, security incidents, malware, etc. In one Google Alert, almost every new article shared with people today by the service led to a scam or malicious website.

Black Arrow Cyber Threat Briefing 18 December 2020
Black Arrow Cyber Threat Briefing 18 December 2020: The great hack attack - SolarWinds breach exposes big gaps in cyber security; A wake-up for the world on cyber security; White House activates cyber emergency response; US nuclear weapons agency targeted; UK companies targeted; Increasing Risk of Cyber Attacks; millions of users install malicious browser extensions; C19 Vaccines sold on dark web
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 Headlines of the Week
The great hack attack: SolarWinds breach exposes big gaps in cyber security
Until this week, SolarWinds was a little known IT software group from Texas. Its deserted lobby has a framed magazine article from a few years ago when it was on a list of America’s “Best Small Companies”.
Now the Austin-based company is at the heart of one of the biggest and most startling cyber hacks in recent history, with ramifications that extend into the fields of geopolitics, espionage and national security.
For nine months, sophisticated state-backed hackers have exploited a ubiquitous SolarWinds software product in order to spy on government and business networks around the world, including in the US, UK, Israel and Canada. Wielding innovative tools and tradecraft, the cyber spies lurked in email services, and posed as legitimate staffers to tap confidential information stored in the cloud.
The bombshell revelations have sent 18,000 exposed SolarWinds customers scrambling to assess whether outsiders did indeed enter their systems, what the damage was and how to fix it.

A wake-up for the world on cyber security
Imagine intruders break into your home and loiter undetected for months, spying on you and deciding which contents to steal. This in essence is the kind of access that hackers, assumed to be Russian, achieved in recent months at US government institutions including the Treasury and departments of commerce and homeland security, and potentially many US companies. If the fear in the Cold War was of occasional “moles” gaining access to secrets, this is akin to a small army of moles burrowing through computer systems. The impact is still being assessed, but it marks one of the biggest security breaches of the digital era.

US government, thousands of businesses now thought to have been affected by SolarWinds security attack
Thousands of businesses and several branches of the US government are now thought to have been affected by the attack on software firm SolarWinds.
The Austin-based company has fallen victim to a massive supply chain attack believed to be the work of state-sponsored hackers.
Along with the US treasury and commerce departments, the Department of Homeland Security is now thought to have been affected by the attack. In a statement to the SEC today, SolarWinds said it had notified 33,000 customers of its recent hack, but that only 18,000 of these used the affected version of its Orion platform.

White House activates cyber emergency response under Obama-era directive
In the wake of the SolarWinds breach, the National Security Council has activated an emergency cyber security process that is intended to help the government plan its response and recovery efforts, according to White House officials and other sources.
The move is a sign of just how seriously the Trump administration is taking the foreign espionage operation, former NSC officials told CyberScoop.
The action is rooted in a presidential directive issued during the Obama administration known as PPD-41, which establishes a Cyber Unified Coordination Group (UCG) that is intended to help the U.S. government coordinate multiple agencies’ responses to the significant hacking incident.
The UCG is generally led by the Department of Justice — through the FBI and the National Cyber Investigative Joint Task Force — as well as the Office of the Director of National Intelligence and the Department of Homeland Security.

Hackers targeted US nuclear weapons agency in massive cyber security breach, reports say
The National Nuclear Security Administration and Energy Department, which safeguard the US stockpile of nuclear weapons, have had their networks hacked as part of the widespread cyber espionage attack on a number of federal agencies.
Politico reports that officials have begun coordinating notifications about the security breach to the relevant congressional oversight bodies.
Suspicious activity was identified in the networks of the Federal Energy Regulatory Commission (FERC), Los Alamos and Sandia national laboratories in New Mexico and Washington, the Office of Secure Transportation, and the Richland Field Office of the Department of Energy.
Officials with direct knowledge of the matter said hackers have been able to do more damage to the network at FERC, according to the report.
Microsoft warns UK companies were targeted by SolarWinds hackers
Microsoft has warned that some of its UK customers have been exposed to the malware used in the Russia-linked SolarWinds hack that targeted US states and government agencies.
More than 40 of the tech giant's customers are thought to have used breached SolarWinds software, including clients in Britain, the US, Canada, Mexico, Belgium, Spain, Israel, and the UAE.
The company would not name the victims, but said they include government agencies, think tanks, non-governmental organisations and IT firms. Microsoft said four in five were in the US, with nearly half of them tech companies.
“This is not ‘espionage as usual,’ even in the digital age,” said Brad Smith, Microsoft's president. “Instead, it represents an act of recklessness that created a serious technological vulnerability for the United States and the world.”
The attackers, believed to be working for the Russian government, got into computer networks by installing a vulnerability in Orion software from SolarWinds.
Society at Increasingly High Risk of Cyber Attacks
Cyber attacks are becoming easier to conduct while conversely security is getting increasingly difficult, according to Kevin Curran, senior IEEE member and professor of cyber security, Ulster University, during a virtual media roundtable.
“Any company you can think of has had a data breach,” he commented. “Whenever a data breach happens it weakens our credentials because our passwords are often reused on different websites.”
He observed that the art of hacking doesn’t necessarily require a significant amount of technical expertise anymore, and bad actors can receive substantial help from numerous and readily accessible tools online. “You don’t have to spend seven years in college to learn how to hack, you just have to know about these sites and what terms to use,” noted Curran.
A number of legitimate online mechanisms that can help damaging attacks to be launched by hackers were highlighted by Curran in his presentation. These include Google Dorks, which are “search strings which point to website vulnerabilities.” This means vulnerable accounts can be identified simply via Google searches.

Three million users installed 28 malicious Chrome or Edge extensions
More than three million internet users are believed to have installed 15 Chrome, and 13 Edge extensions that contain malicious code, security firm Avast said today.
The 28 extensions contained code that could perform several malicious operations, including:
-redirect user traffic to ads
-redirect user traffic to phishing sites
-collect personal data, such as birth dates, email addresses, and active devices
-collect browsing history
-download further malware onto a user's device
But despite the presence of code to power all the above malicious features, Avast researchers said they believe the primary objective of this campaign was to hijack user traffic for monetary gains.

Vaccines for sale on dark web as criminals target pandemic profits
Black market vendors were offering coronavirus vaccines for sale on hidden parts of the internet days after the first Covid-19 shot was approved this month, as criminals seek to profit from global demand for inoculations.
One such offer on the so-called dark web, traced by cyber security company Check Point Software, was priced at $250 with the seller promising “stealth” delivery in double-wrapped packaging. Shipping from the US via post or a leading courier company would cost $20, with an extra $5 securing overnight delivery.
