# 5 BIG lessons recent cyber attacks teach us

The world relies on technology more than ever before. As a result, digital data creation has surged. Devices and their underlying systems have vulnerabilities that, when exploited, undermine the health and objectives of an organization.In this article we will be talking about cyber security attacks in the recent times and 5 big lessons we can learn from these. 

![recent-cyber-attacks](https://blog.savincom.co.uk/hs-fs/hubfs/recent-cyber-attacks.jpg?width=704&name=recent-cyber-attacks.jpg)

### What is cyber security?

Cybersecurity is comprised of an evolving set of tools, risk management approaches, technologies, training, and best practices designed to protect networks, devices, programs, and data from attacks or unauthorized access. It refers to the body of technologies, processes, and practices designed to protect networks, devices, programs, and data from attack, damage, or unauthorized access. Cyber security may also be referred to as information technology security.

### What are the TOP 5 types of recent cyber attacks?

1. Denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks
2. Phishing and spear phishing attacks
3. Password attack
4. Eavesdropping attack
5. Malware attack

### Most notorious recent cyber attacks

#### 1. Experian breach in 2020

A consumer credit reporting agency, Experian, suffered a big breach in August 2020. This affected almost 24 million consumers and nearly 800,000 businesses. The credit agency admitted to handing over the personal details of its South African customers to a fraudster posing as a client. Experian said that none of the data has been used for fraudulent purposes before being deleted and that the fraudster did not compromise its infrastructure, systems, or customer database.

#### 2. Zynga cyber attack in 2019

In September 2019, a hacker claimed to have hacked into Zynga's (Facebook entity) database of Draw Something and Words with Friends players and gained access to the 218 million accounts registered there. Zynga later confirmed that email addresses, hashed passwords, phone numbers, and user IDs for Facebook and Zynga accounts were stolen.

#### 3. Canva attacked in 2019

In May 2019 Australian graphic design tool website Canva suffered an attack that exposed email addresses, usernames, names, cities of residence, and salted and hashed with bcrypt passwords (for users not using social logins — around 61 million) of 137 million users. Canva says the hackers managed to view, but not steal, files with partial credit card and payment data.

#### 4. Marriott attack in 2018

Information from up to 500 million guests at the Marriott-owned Starwood hotel group had been compromised, including banking data. The rift had been open since 2014 and was first spotted September 2018. Even if, as Marriott says, the number of customers that suffered a breach of personal information is anywhere near 327 million, the implications are massive. Information accessed included payment information, names, mailing addresses, phone numbers, email addresses, passport numbers, and even details about the Starwood Preferred Guest (SPG) account, a high-end card recently launched by the American Express credit card issuer for regular travellers.

#### 5. Adobe cyber attack in 2013

Adobe originally reported that hackers had stolen nearly 3 million encrypted customer credit card records, plus login data for an undetermined number of user accounts. Later, Adobe raised that estimate to include IDs and encrypted passwords for 38 million “active users. Weeks of research showed that the hack had also exposed customer names, IDs, passwords and debit and credit card information.

#### 6. Google China hit by cyber attack in 2009

Hackers had gained access to several Google’s corporate servers and intellectual property was stolen. In a blog, Google said it has “evidence to suggest that a primary goal of the attackers was accessing the Gmail accounts of Chinese human rights activists”. As the company dug deeper, they found numerous Gmail of users from US, China and Europe had been routinely been accessed without permission. Those emails belonged to advocates of human rights in China. The cyber attacks in December 2009 resulted in the company’s re-evaluation of its business in the country.

### What lesson do we learn from recent cyber attacks?

We suggest having a solid security baseline, in which you ensure the most obvious risks are addressed early. There are a few lessons you should keep in mind and apply to keep cyber attacks at bay.

#### 1. No system is safe

Don’t be complacent — limit Internet access points with silos.

#### 2. Keep testing your infrastructure

Keeping the critical infrastructure efficient and effective is challenging enough. Yet finding the time to consistently audit and always be improving security is critical too. Attackers will be looking for [mis-configurations or flaws](https://www.redteamsecure.com/blog/business-insider-rides-shotgun-as-redteam-security-hacks-the-power-grid) that offer access — it’s up to you to find those entry points first.

#### 3. Train and educate your staff

Making your people aware of the importance of physical measures — even locking cabinets and supporting the security intentions of access control doors can make a difference.

It is very important to educate employees to always be vigilant and raising awareness of potential threats.

#### 4. Stay up-to-date

Keep updating your software from time-to-time.  Concerns that new operating systems or software updates might destabilize crucial infrastructure can inhibit the best practice of always updating. But cyber criminals keep looking for one loop hole to get in and create havoc.

#### 5. Seek expert help

Savincom can give you the requisite and recommended [cyber security](https://www.savincom.co.uk/cyber-security/)expert help. They know best practices and think like hackers and system engineers to test security control effectiveness and offer advice for remediation.

### Risk of cyber attacks whilst working remotely

![remote](https://blog.savincom.co.uk/hs-fs/hubfs/remote.jpg?width=690&name=remote.jpg)

The quick spread of the covid 19 pandemic triggered an equally quick transition toward a remote workforce among many organizations across the globe. But because of the abruptness of that shift, security has sometimes taken a back seat as organizations rushed to ramp up this new and evolving environment.

The coronavirus pandemic and lockdown have impacted individuals and organizations in myriad ways. One side effect has been of cybersecurity risks. As cybercriminals have exploited the virus with malicious attacks and employees have transitioned to remote work, organizations have had to reorient and redirect their security efforts.

#### [1. Unreliable Internet Connections](https://blog.savincom.co.uk/is-your-internet-connection-secure-to-work-from-home-1)

The problem with public Wi-Fi or other unreliable internet connections is that there are a tremendous number of risks that go along with these networks. In 2021, with remote working becoming the new normal for many businesses, cybersecurity risks like unsafe internet connections are to be dealt with seriously. While business owners may believe they’re providing a valuable service to their customers, chances are the security on these networks is lax or nonexistent.

#### 2. Phishing attacks via malicious emails

The number of phishing attacks and other email-based cyber-criminal campaigns continues to rise, with most organisations having witnessed an increase over the past year – but despite this, under half of the businesses provide awareness training about cyber threats on a frequent basis.

I would like to thank savincom for the hard work that they have done, they have managed to meet all our requirements and have delivered it in a timely fashion. They have reduced our monthly outgoings for our mobiles by a 1/5 of which we are very happy about.

 Maintenance Manager, Luxury Hotel Group

Since moving to Savincom, we have received excellent and responsive customer service, the small number of issues we have experienced have been resolved in an efficient and expert manner. We have significantly reduced our running costs, with the proactive account management, currently running a reduction of c.40% on costs, the cost reduction has been most prevalent around roaming and international calling. The transfer from Vodafone Direct to Savincom Vodafone was smooth and seamless, with onsite support offered during the days of the transfer. If I was to score them out of 10, it would be 10 as the have excelled as a service partner.

 Office Manager, Leading Global Commodity Merchant

We have worked with Savin Communications for four years now and we are delighted with the work carried out so far.  We have 300+ connections, so service needs to be of the highest quality, which is what we get with Savin Communications. We have a rapid staff turnover and Savin assist us when utilising connections. We used to be on a plan where we were constantly going over minutes and data allowances. Savin Communications has helped us source a much better quality plan and they understand the high standards that our organisation have and are most efficient in delivering well within time limits…. The account manager is always easy to contact and help is really appreciated, meetings with him are regular. The assistance and support we receive is always   
 responsive, proactive and excellent at all times. The advice given is easy to understand along with their online portal which is easy to use too, communicated in a friendly accessible manner. I would highly recommend Savin Communications.

 ICT Manager, National Charity

Having paid overly expensive mobile phone bills for several years, we switched to Savincom who assured us of substantial savings, especially for our mobile phone usage abroad. They were not wrong! Our bills have practically halved since the switch and furthermore Savincom provide a great support service, with any queries or problems being acknowledged and dealt with swiftly and professionally.

 Finance Manager, Global Shipping Company

I can confirm that we switched over our account from a direct one held with one of the Networks, to one under Savincom’s control and have been more than happy with the service thus far. As a Canadian Investment Bank with frequent overseas travellers, I found doing business direct with the Network over the past few years and my numerous dedicated account managers very frustrating indeed. Wrong price plans, outdated tariffs, changes of Account Managers, limited cover on the weekend support desk, and bolt -on’s not being applied to our overseas travellers etc. We are seeing benefits in not having to deal with the Network directly. I would be happy to recommend them in terms of the mobile contract that they proposed and especially their customer service.

 Operations Manager, Investment Bank

Since using Savincom our bills have noticeably decreased and every possible bundle is being added and removed when necessary. The service levels are a world away from what we experienced previously; I get a response back from their support team in at least 5 minutes, and everyone is extremely helpful. The account management is makes a big difference as well. Everything is straightforward and I can request information on our account and be sent a detailed report. I would highly recommend Savincom.

 Office Manager, Investment Company

I have used Savin for the last 4 years and their customer service, support, timescale to response and resolve any queries etc. has been first class! I am the IT Manager for a large construction based Group and as you can appreciate we have a large number of guys based on construction sites who break their phone frequently (and lose them!) so I require a swift service to replace phones and sims, bar phone lines and order new lines (either phone or 4G dongles) ASAP, all of which Savin deliver! So I would recommend Savin without hesitating!

 IT Manager, Construction Group

The highlight for me is being able to shoot an email to Savincom support and almost   
 immediately getting an engaging response, they want to solve my problems rather   
 than assign blame to someone. Overall we are very pleased to be working with a great team.

 IT Manager, Private Equity

Savincom are my righthand. I just phone and everything gets dealt with – no more long maddening calls to mobile providers. Thank you Savincom. You guys rock!

 Andrea Sequeira

Not only have our monthly bills been cut by more than half, savincom saved hours of my time spent on the phone to network direct customer support lines.

 Sujin Bailey

Having had our mobile phone contracts managed by savincom has saved the company considerable time and administrative effort.
