The Index assesses the cybersecurity risk of countries worldwide, with a lower rank indicating higher risk and a higher rank indicating lower risk.

The May 2024 Index highlights significant variations in cybersecurity risk levels across African countries. Egypt ranked highest on the Index among the 111 countries surveyed, followed by Namibia (108th) and South Africa (68th). Ethiopia and Zimbabwe faced the highest risks, being placed second and third respectively on the Index. Other African countries continue to face cybersecurity challenges with Angola (5), Maldives (6), Kenya (9), Ghana (11), Mauritius (18), Morocco (21), Uganda (23) and Nigeria (40) having among the lowest rankings.

“Egypt, Namibia and South Africa’s positions in the Global Threat Index for May 2024 underscore the effectiveness of their strategic approaches to cybersecurity,” says Vincent Mabaso, Distribution Lead: Africa, Check Point Software Technologies. “Their success serves as a model for other African nations striving to improve their cybersecurity posture.”

LockBit is back!

Last month, researchers uncovered a malspam campaign orchestrated by the Phorpiex botnet. The millions of phishing emails sent contained LockBit Black – based on LockBit3 but unaffiliated with the Ransomware group. In an unrelated development, the actual LockBit3 ransomware-as-a-Service (RaaS) group surged in prevalence after a short hiatus following a global takedown by law enforcement, accounting for 33% of published attacks.

The original operators of the Phorpiex botnet shut down and sold the source code in August 2021. However, by December 2021, Check Point Research (CPR) discovered it had reemerged as a new variant called “Twizt”, operating in a decentralized peer-to-peer model.

In April of this year, the New Jersey Cybersecurity and Communications Integration Cell (NJCCIC) (https://apo-opa.co/4ceXqPc) found evidence that Phorpiex botnet, which ranked sixth in last month’s threat index, were being used to send millions of phishing emails as part of a LockBit3 ransomware campaign. These emails carried ZIP attachments (https://apo-opa.co/4ceXtum) that, when the deceptive .doc.scr files within were executed, triggered the ransomware encryption process. The campaign used over 1,500 unique IP addresses, primarily from Kazakhstan, Uzbekistan, Iran, Russia, and China.

Meanwhile, the Check Point Threat Index highlights insights from “shame sites” run by double-extortion ransomware groups posting victim information to pressure non-paying targets. In May, LockBit3 reasserted its dominance, accounting for 33% of published attacks. They were followed by Inc. Ransom with 7% and Play with a detection rate of 5%. Inc. Ransom recently claimed responsibility for a major cyber incident that disrupted public services at Leicester City Council (https://apo-opa.co/4bUharv) in the UK, allegedly stealing over 3 terabytes of data and causing a widespread system shutdown.

“While law enforcement bodies managed to temporarily disrupt the LockBit3 cybergang by exposing one of its leaders and affiliates in addition to releasing over 7,000 LockBit decryption keys (https://apo-opa.co/3KHKcim), it is still not enough for a complete takedown of the threat. It is not surprising to see them regroup and deploy new tactics to continue in their pursuits,” said Maya Horowitz, VP of Research at Check Point Software.

“Ransomware is one the most disruptive methods of attack employed by cybercriminals. Once they have infiltrated the network and extracted information, the options are limited for the target, especially if they cannot afford to pay the ransom demands. That is why organisations must be alert to the risks and prioritise preventative measures.”

Top malware families

*The arrows relate to the change in rank compared to the previous month.

FakeUpdates was the most prevalent malware last month with an impact of 7% worldwide organisations, followed by Androxgh0st with 5%, and Qbot with 3%.

1. ↔ FakeUpdates – FakeUpdates (AKA SocGholish) is a downloader written in JavaScript. It writes the payloads to disk prior to launching them. FakeUpdates led to further compromise via many additional malware, including GootLoader, Dridex, NetSupport, DoppelPaymer, and AZORult.

2. ↔ Androxgh0st – Androxgh0st is a botnet that targets Windows, Mac, and Linux platforms. For initial infection, Androxgh0st exploits multiple vulnerabilities, specifically targeting- the PHPUnit, Laravel Framework, and Apache Web Server. The malware steals sensitive information such as Twilio account information, SMTP credentials, AWS key, etc. It uses Laravel files to collect the required information. It has different variants which scan for different information.

3. ↔ Qbot – Qbot AKA Qakbot is a multipurpose malware that first appeared in 2008. It was designed to steal a user’s credentials, record keystrokes, steal cookies from browsers, spy on banking activities, and deploy additional malware. Often distributed via spam email, Qbot employs several anti-VM, anti-debugging, and anti-sandbox techniques to hinder analysis and evade detection. Commencing in 2022, it emerged as one of the most prevalent Trojans.

Top exploited vulnerabilities 

Last month, “Command Injection Over HTTP” was the most exploited vulnerability, impacting 50% of organisations globally, followed by “Web Servers Malicious URL Directory Traversal” at 47% and “Apache Log4j Remote Code Execution” with 46%.

1. ↔ Command Injection Over HTTP (CVE-2021-43936, CVE-2022-24086) – A command Injection over HTTP vulnerability has been reported. A remote attacker can exploit this issue by sending a specially crafted request to the victim. Successful exploitation would allow an attacker to execute arbitrary code on the target machine. 

2. ↔ Web Servers Malicious URL Directory Traversal (CVE-2010-4598,CVE-2011-2474,CVE-2014-0130,CVE-2014-0780,CVE-2015-0666,CVE-2015-4068,CVE-2015-7254,CVE-2016-4523,CVE-2016-8530,CVE-2017-11512,CVE-2018-3948,CVE-2018-3949,CVE-2019-18952,CVE-2020-5410,CVE-2020-8260) – There exists a directory traversal vulnerability On different web servers.

Top-Attacked Industries in Africa

According to the data, the top attacked industries last month in Africa were:

Government/Military
Finance/Banking
Communications

Last month, Education/Research remained in first place in the most attacked industries globally, followed by Government/Military and Communications.

Top Ransomware Groups

The following data is based on insights from ransomware “shame sites” run by double-extortion ransomware groups that post victim information. Last month, LockBit3 was the most prevalent ransomware group last month, responsible for 33% of the published attacks, followed by Inc. Ransom with 7% and Play with 5%.

LockBit3 – LockBit3 is a ransomware, operating in a RaaS model, first reported in September 2019. LockBit targets large enterprises and government entities from various countries and does not target individuals in Russia or the Commonwealth of Independent States. Despite experiencing significant outages in February 2024 due to law enforcement action, LockBit has resumed publishing information about its victims.
Inc. Ransom – Inc. Ransom is a ransomware extortion operation that emerged in July 2023, performing spear-phishing attacks and targeting vulnerable services. The group’s main targets are organisations in North America and Europe across multiple sectors including healthcare, education, and government. Inc. ransomware payloads support multiple command-line arguments and uses partial encryption with a multi-threading approach.
Play – Play Ransomware, also referred to as PlayCrypt, is a ransomware that first emerged in June 2022. This ransomware has targeted a broad spectrum of businesses and critical infrastructure across North America, South America, and Europe, affecting approximately 300 entities by October 2023. Play Ransomware typically gains access to networks through compromised valid accounts or by exploiting unpatched vulnerabilities, such as those in Fortinet SSL VPNs. Once inside, it employs techniques like using living-off-the-land binaries (LOLBins) for tasks such as data exfiltration and credential theft.

“While there are commonalities in the industries targeted by cybercriminals across different regions, specific sectors such as Government/Military, Finance/Banking, and Communications are consistently at high risk. African countries must continue to enhance their cybersecurity measures to protect these critical industries from evolving threats

Ransomware and the other cyber threats listed are among the most disruptive methods employed by cybercriminals globally. Organisations must be proactive, not reactive, in their cybersecurity strategies. Preventative measures, continuous monitoring, and rapid response protocols are crucial to mitigating the impact of these attacks,” Mabaso concludes.
