How to Successfully Recover from a Ransomware Attack

South Africa is an attractive target for cybercriminals for a number of reasons, and the last few years have seen a sharp rise in high-profile ransomware attacks. One of the key motivations driving this volume of attacks is the fact that data is a de facto currency and an extremely valuable commodity on the black market. While backup is a critical component of data protection, when this backup is also encrypted by malicious software, companies are often left with few options other than to pay the ransom. Therefore, an effective Cyber Recovery strategy, which enables businesses to get back up and running without having to give in to criminal demands, is the key. Continue reading Image: Kaspersky

3 Most Common Cyberscams that Compromise Business Emails

Online security firm Kaspersky reports that its cybersecurity experts are increasingly observing BEC (Business Email Compromise) attacks online. Between May and July 2021, Kaspersky says that its security products prevented more than 9,500 BEC attacks globally, including those against businesses in air transportation, industry, retail, IT, and delivery. Such attacks demand significant time and resources, and preparation for them may last from a few weeks to several months. One successful attack may lead to damage worth many millions for a company. During a BEC attack, fraudsters usually initiate an email exchange with a company employee in order to gain their trust and encourage actions that are detrimental to the interest of the company or its clients.

5.8-Million Attacks Detected in Malware Disguised as PC Games

Over 5.8 million attacks by malware and unwanted software disguised as popular PC games were detected and prevented by Kaspersky and its cybersecurity solutions globally from Q3 2020 to Q2 2021. This increased volume may be connected to the rapid growth of gaming activities during the pandemic. The data comes from the latest game-related cyberthreats report by Kaspersky, in which researchers assessed the changes of gaming-related threats during the pandemic. The gaming industry witnessed unprecedented growth over the past 18-months, in part, thanks to users being forced to find alternative means of entertainment as they stayed at home. Even though the world has become safer this year, the demand for games persists, and the industry is predicted to grow even further, reaching a po...

Malware Spreading Through Popular WhatsApp Mod Uncovered

A malicious version of a popular WhatsApp messenger mod (unofficial modification of the app) called FMWhatsapp has been discovered by cybersecurity firm Kaspersky. This mod spreads the Triada mobile Trojan, which downloads other Trojans and can launch ads, issue subscriptions, and intercept a user’s SMSs. Even though WhatsApp is one of the most popular apps for instant mobile messaging, not all users are satisfied with its features. Looking for the most user-friendly version, people can be tempted to install modified versions of WhatsApp, which provide many more options than the official one (such as choosing dynamic templates or the ability to read deleted messages). However, these modified apps do not have the same security and encryption features that the official version o...

Explained: Can the Nigerian government really spy on your WhatsApp messages?

Barely a month after blocking access to Twitter, the Nigerian government allocated ₦1.93 billion ($4.6 million) to the National Intelligence Agency (NIA) for a “WhatsApp Intercept Solution”. An interception solution for WhatsApp would allow an external party (the government, in this case) to access, monitor, or block communications (calls and chats) carried out by users via the app. The move is reportedly aimed at protecting Nigeria from cybercrime and terrorism perpetrated through such messaging platforms. However, it is seen by media stakeholders and activists as yet another attempt to restrict civil liberties. Continue reading

Crypto hacker offered reward after $600m heist

A hacker who stole just over $600m (£433m) worth of cryptocurrency was offered $500,000 and immunity as a reward for returning the money. Poly Network made the controversial offer after the hacker pledged to send back the money. The attack was uncovered on Tuesday when Poly Network publicly pleaded with the hacker to help. One former FBI official said "private companies have no authority to promise immunity from criminal prosecution". The attack is one of the largest hacking heists in history. Poly Network said the person had exploited a vulnerability in its system. Most of the money has now been given back, although the hacker says they are not interested in the reward.
