Working remotely during Summer 2023: 5 steps to protect yourself from cyberattacks according to Sophos
With the arrival of summer, teleworking becomes the priority option for many workers, but it is necessary to take into account the risks and threats involved in moving the workspace to a new location
Before the pandemic, cybersecurity started to be considered as a fundamental area in a company.
But it’s really after the implementation of teleworking during confinement and the cyberattacks that many companies suffered, due to the exposure of their devices, that IT teams are increasingly focused on raising awareness among their workers.
The objective is clear, shield each access point to the business network and monitor it to avoid active threats, making remote work a secure and flexible option.
“At the time the health emergency arose, companies had to apply various measures to continue operating from home, but, although the crisis passed and companies returned to normality, teleworking has remained in many cases. In the first instance, it is the companies that are taking measures to increase their levels of cyber protection, but in addition to that, users can also take measures that accompany them and that allow them to telework from wherever they want while maintaining protection”, explains Chester Wisniewski, Field Sophos CTO.
Flexibility or family reconciliation are some of the advantages offered by this modality, so it is not surprising that it is an option that many workers choose for the summer season. Although at an operational level changing workplaces seems simple, it is important to take into account a protocol for prior actions. Cybersecurity experts at Sophos, a global leader in innovation and delivery of cybersecurity as a service, offer five steps to take to avoid risk and concern in what should be a happy and pleasant time:
1. Previous preparation. Just as you must prepare your devices and materials to establish your office in the new destination, you cannot forget to condition them internally, for this, check that your devices have the appropriate security software installed and that they comply with the compliance policies and security of your organization. solutions are patched and protected.
2. Training. Most cyberattacks start with a vulnerability in the weakest link in the chain, that is, the users. Workers can be the gateway used by attackers to access the rest of the company’s devices. This makes it necessary that, as a worker, it is important to acquire basic knowledge to know how current and identify in time if you are being attacked, either by your company or by your own account.
3. Double check. If you receive an unexpected communication from a coworker or business that seems out of the ordinary, don’t respond directly, rather contact the person or organization using another communications method like phone or SMS to ensure they are who they say they are.
4. Apply updates as soon as they are available. This is easiest on our phones and computers as we are usually prompted to update them, but don’t forget your internet router and smart home things. It is a good practice to check them all for available updates at least once a quarter.
5. Don’t forget to keep the “essentials”. Finally, despite carrying out all the previous steps, we must not forget the most basic protection measures that represent the entry barrier. First, set unique passwords for all your accounts and use a password manager to help keep them long and secure. Ideally, use multi-factor or “two-step” authentication wherever available to provide additional protection.
“Today most devices are used when connected to the internet, so you have to maintain a mindset where devices are considered to be in a hostile environment at all times. The idea that the safe space is inside offices and the insecure one outside is outdated. Now, anywhere you can suffer an attack, but it is true that sometimes when we move along with our workplace we do not take the necessary tools with us, so it is important to be vigilant”, adds Chester Wisniewski.
…Nearly 80% of Organizations Hit by Ransomware Took More than a Week to Recover
Sophos, a global leader of innovative security solutions for defeating cyberattacks, today released a sector survey report, “The State of Ransomware in Healthcare 2024,” which revealed that the rate of ransomware attacks against healthcare organizations has reached a four-year high since 2021.
Of those organizations surveyed, two-thirds (67%) were impacted by ransomware attacks in the past year, up from 60% in 2023.
The rising rate of ransomware attacks against healthcare institutions contrasts with the declining rate of ransomware attacks across sectors; the overall rate of ransomware attacks fell from 66% in 2023 to 59% in 2024.
Alongside an increase in the rate of ransomware attacks, the healthcare sector reported increasingly longer recovery times.
Only 22% of ransomware victims fully recovered in a week or less, a considerable drop from the 47% reported in 2023 and 54% in 2022.
In addition, 37% took more than a month to recover, up from 28% in 2023, reflecting the increased severity and complexity of attacks.
“While we’ve seen the rate of ransomware attacks reach a kind of “homeostasis” or even decline across industries, attacks against healthcare organizations continue to intensify, both in number and scope. The highly sensitive nature of healthcare information and need for accessibility will always place a bullseye on the healthcare industry from cybercriminals. Unfortunately, cybercriminals have learned that few healthcare organizations are prepared to respond to these attacks, demonstrated by increasingly longer recovery times. These attacks can have immense ripple effects, as we’ve seen this year with major ransomware attacks impacting the healthcare industry and impacting patient care,” said John Shier, field CTO, Sophos.
“To combat these determined adversaries, healthcare organizations must adopt a more proactive, human-led approach to threat detection and response, combining advanced technology with continuous monitoring to stay ahead of attackers.”
Additional findings from the report include:
· Ransom Recovery Costs Surge: The mean cost of recovery in a healthcare ransomware attack was $2.57 million in 2024, up from $2.2 million in 2023 and double the 2021 cost
· Ransom Demands vs Payments: 57% of healthcare institutions that paid the ransom ended up paying more than the original demand
· Root Cause of Attack: Compromised credentials and exploited vulnerabilities were tied for the number one root cause of attack, each accounting for 34% of attacks
· Backups Targeted: 95% of healthcare organizations hit by ransomware in the past year said that cybercriminals attempted to compromise their backups during the attack.
· Increased Pressure: Organizations whose backups were compromised were more than twice as likely to pay the ransom to recover encrypted data (63% vs. 27%)
· Who Pays the Ransom: Insurance providers are heavily involved in ransom payments, contributing in 77% of cases. 19% of total ransom payment funding comes from insurance providers
The latest Sophos report on real-world ransomware experiences explores the full victim journey, from attack rate and root cause to operational impact and business outcomes, of 402 healthcare organizations.
The results for this sector survey report are part of a broader, vendor-agnostic survey of 5,000 cybersecurity/IT leaders conducted between January and February 2024 across 14 countries and 15 industry sectors.
Boxes have a multitude of uses, and the word “box”, lends itself to diverse contexts. For “Ajala Travelers,” the box is a necessity for keeping goods for their endless journeys. In literature, idiomatically, it can be said that “one has been boxed into a corner;” another might say to deal with a conundrum: “think outside the box;” then there is the “Pandora’s box” that no one wants opened.
To “box one’s ear’s” refers to a hit on the head, especially around one’s ears. For those who celebrate Christmas, “Boxing Day,” which is the 26th of December, the second day of Christmastide is not to be joked with: A day to unbox gifts. So much for the box.
Another type of boxes exists in the telecommunications world: The SIM Box. Have you ever received an international call but saw a local phone number ring in? That is SIM Boxing in action. Let me explain.
SIM boxing happens when a person uses a special equipment, what is called a SIM Box containing tens to hundreds of SIM Cards—from 32, to 96, to 512 and more SIMs —to terminate international calls by bringing in the international call into the SIM Box using internet connections and regenerating the calls to the called party from one of the hundred SIMs in the box.
This way, the called party will see the local number of the SIM from the SIM Box, and not the original international number calling.
With SIM Boxes, the syndicate charges international call carriers lower rates than what regular Nigerian telecommunications operators would charge, as they do not have to pay the full cost of maintaining and operating a phone network.
Basically, they are bypassing the normal route for international phone call termination to terminate international calls cheaply and making windfall profits off it.
Take for instance, a telecommunications operator in Nigeria would ordinarily charge international carriers 10cents per minute for terminating an international call in Nigeria. However, by routing the call through a SIM Boxing syndicate, the international telecommunications carrier only pays a fraction of the charge to the syndicate, say 5cents per minute and does not have to pay the full 10cents per minute charge.
The SIM Boxer will terminate this call to the called subscriber at a rate of, say N15 per minute using one of the SIM cards in their SIM Box. The SIM Boxer thus makes a killing from the differential between the rate charged to the international carrier and the rate paid to telecommunications operators whose SIM they utilise in their SIM Boxes, at the expense of our national security and income of mobile network operators and quality of our service to consumers.
Asides the revenue loss that local mobile network operators suffer courtesy the activities of these syndicates, networks face congestion around areas where the illegal call routings via SIM Boxing occurs. With the huge traffic from the boxes, callers around the area see more dropped calls, poor call quality, and slower data speeds.
The introduction of the linking of National Identity Numbers (NIN) to SIMs is one way the Federal Government has worked to tackle this criminal enterprise. With every SIM in the country being linked to an NIN, an identity is tied to the owner of each line, and regulators now have visibility of ownership. That is not all. There is also the “Max-4 Rule” where a subscriber is not allowed to have more than four lines per network operator linked to his NIN. With this rule in place, coupled with the NIN-SIM Linkage, every telephone subscriber in Nigeria would not just be accurately identifiable but limited to having only four telephone lines per subscriber.
To enforce this rule, the Nigerian Communications Commission (NCC) on the 29th of March 2024 announced the deadline for Mobile Network Operators to bar all subscribers who had five lines and above, and whose NIN failed the verification test of biometrics matching.
Over the last few weeks, sources within the NCC have confirmed cases where a single NIN was linked to over 100,000 lines.
Some NINs had well over 10,000 SIMS linked to them, others over a thousand, others had hundreds. Many have questioned the reports and asked, what would any single reasonable person be doing with these number of lines? Justifiable questions, because no sane person—who is not running a business—should own more than five SIM cards.
Given the ‘Max 4 Rule’ in place and the NIN-SIM Linkage Policy, SIM Boxers have been boxed into a corner.
The applications they use require tens to thousands of SIM Cards, and the imperative to stay anonymous. If these policies are well and fully implemented, this is the death knell for SIM Boxing merchants.
But the regulator, NCC needs to be fast and ready for the battle ahead. SIM Boxing is a billion-dollar criminal enterprise. They are not going to go down without a fight. It is like taking a bone being chewed from the mouth of a bulldog.
Already, the battle seems to have kicked off. A lawyer, Barrister Olukoya Ogunbeje has recently taken the Federal Government, NCC and Mobile Network Operators to court, claiming that the barring of SIMs not linked to NINs goes against his fundamental human rights, and has cost him the loss of business opportunities.
Anyone who has Nigeria’s interest at heart ordinarily supports this policy. It then does not add up seeing a so-called activist lawyer take up such a matter that is clearly against the public interest—unless this is the Haka cry of SIM Boxers.
A most interesting observation with his case is that it is not even a class action, but individually driven. It begs the question then, who is funding Barr. Olukoya Ogungbeje? What is his interest in fighting this policy that puts paid to the business of a criminal enterprise? Is he funded by interests in the SIM Boxing world? Time would tell. But in the meantime, NCC must go head on without fear or intimation and clean the Augean stable of SIM ownership in Nigeria.
