SA sees spike in network attacks

According to Kaspersky, a major spike in network attacks took place in South Africa last week. Affected devices increased from 20,000-30,000 to about 310,000 in the period spanning from 15 – 21 March.

This has coincided with an increase in remote working in the country, after President Cyril Ramaphosa announced first a National State of Disaster and then a 21-day lockdown.

“Remote working provides cybercriminals a prime opportunity to target devices, especially those that don’t necessarily have adequate IT security measures in place,” Maher Yamout, senior security researcher for the Global Research and Analysis Team at Kaspersky, said in an interview with MyBroadband.

“Such a spike recorded, although temporary, leads us to believe that cybercriminals have keenly been focused on the region given the current circumstances.”

Protecting your networking during lockdown

Kaspersky provided a variety of tips employees should follow when working remotely during the impending lockdown:

  • Make use of a VPN to connect securely to the corporate network
  • Use multi-factor authentication wherever possible
  • Ensure all corporate devices – including mobiles, laptops and tablets are protected with adequate security software
  • Segregate your personal devices/life from corporate computers
  • Ensure the latest available updates are installed regularly
  • Only use corporate-approved teleconferencing software
  • Practice basic cybersecurity rules

 

Top cybersecurity tips for small businesses

Small businesses and self-employed people are big targets for hackers, and the financial implications can be crippling. Gone are the days of thinking “It’ll never happen to us.” A total of 61% of all data breaches this year occurred in businesses with fewer than 1,000 employees, according to the Verizon Data Breach Investigations Report. So, if you would like to keep your workforce educated about potential cyber threats, schedule your employees for cyber security training for beginners.
Not only have hacks increased in frequency, but the impact on SMEs is getting much bigger.

But where do you begin? Many SMEs feel that being as secure as a big business is impossible. Corporations have large budgets, chief security officers and entire teams dedicated to cybersecurity. This perception stems from the impression that hacks are vastly complicated, and rely on a tireless horde of highly skilled attackers. Most hacks aren’t like that. The majority depend on poor passwords and a lack of awareness of what a hacker actually needs to compromise your systems — a simple phishing email or a leaked password and they’re in. It’s that simple.

Educating yourself and your staff is the only solution. Hackers always look for soft targets, so start with the basics. Here are some tips from Hightower Risk:

1. Get a strong password

A total of 80% of hacking-related breaches use either stolen passwords and/or weak or guessable passwords. Getting a strong password is the bare minimum. What’s more, it’s easier than you think. A lot of people don’t know that you can use spaces in your passwords, for example: “horse mug table” is much a much better password than “Horse123.”

2. Then make your password unique

Having a single strong password doesn’t count for much if that password then gets leaked. We’ve seen massive, trusted companies like LinkedIn and Yahoo leak millions of passwords over the last few years, which opens the door to wide-ranging cyber attacks. Password managers like LastPass and OnePassword help you generate and keep track of unique and strong passwords.

3. Know what to look out for with phishing

Hackers are constantly sending “phishing” emails, trying to get you to click on their website so that they can install malware or convince you to give them your password. Understanding what a hacker is trying to do and what to look out for is key. Poor syntax, incorrect spelling, or email addresses and links that include a lot of full stops (for example, amazon.getcode.tickets.phishingattack.com ) are all key warning signs to look out for.

4. Understand the information you’re already giving away

Phishing attacks rely on the amount of information we share about ourselves online. Famously the hackers behind the celebrity iCloud leak in 2014 used information they’d gained from public posts to guess the answers to user’s secret questions. If your secret question is “The city I was born in” and you post that information on Facebook, then hackers have an easy way into your account.

5. Pay attention to Web page URLs

When you see “http” in a web page URL that means your communication with that page is unencrypted. Any communication could be easily read by a hacker waiting on that page; “http” is a warning sign to look out for if you ever think you might have stumbled onto a phishing or generally suspect website. If you’re ever entering sensitive information like credit card numbers or personal details, make sure the website has “https” in the website url. That way you’re more secure.

6. Update your software

Software is updated for a reason. Usually companies like Microsoft or Apple will discover a vulnerability that might let hackers in, fix it, then offer an update. Always take them up on it. We saw with the WanaCry attack earlier this year what happens when organizations don’t install patches (updates bringing computer systems to the most up-to-date version) and security updates. Unpatched vulnerabilities offer gaps into your systems that hackers use to install malware and ransomware, or to just gain control of your systems.

7. Encrypt everything

Should a breach happen, you want to make sure whatever information hackers get their hands on is, at the very least, difficult for them to understand. Encrypting your hard drives and databases with a modern algorithm like AES256 is a key defensive tool to protect your data in the event of a breach. It’s quick and easy to do.

Knowledge is the key to cybersecurity, but it’s important to think about the underlying structure of your business and the way it handles data more broadly. Organization-wide controls and data-protection policies help define sound technological defense, and ensure you know how to respond in the event of a breach. Just remember that industry standards like an ISO27001 certification and SOCII are beneficial, but only when combined with education and good user behavior.
