Sophos Identifies Top Ransomware Families in Africa

Cyber security vendor Sophos has identified the top ransomware families that affected Africa in 2017.

According to Sophos, the Ceber ransomware accounted for 80% of attacks in Africa, followed by WannaCry (17%), and others like Jaff (1%), Locky (1%) and Petya (0.5%).

One of the most active kinds of ransomware out there, Cerber encrypts the files of infected users and demands money in exchange for enabling access to their files. It works even if a user is not connected to the Internet, so they can’t stop it by unplugging their PC.

Cerber, sold as a ransomware kit on the Dark Web, remains a dangerous threat, says Sophos, adding the creators of Cerber continuously update the code and charge a percentage of the ransom that the “middle-men” attackers receive from victims.

Regular new features make Cerber not only an effective attack tool, but perennially available to cyber criminals, the cyber security firm notes.

“This Dark Web business model is unfortunately working and, similar to a legitimate company, is likely funding the ongoing development of Cerber. We can assume the profits are motivating the authors to maintain the code,” says Dorka Palotay, SophosLabs security researcher and contributor to the ransomware analysis in the SophosLabs 2018 Malware Forecast.

The WannaCry ransomware attack was a May 2017 worldwide cyber attack by the WannaCry ransomware cryptoworm, which targeted computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in the Bitcoin crypto-currency.

“Looking at the whole world, WannaCry was responsible for 45.3% of the ransomware attacks, while in Africa this value is only 17%,” Palotay says.

“In Africa, clearly Cerber was the biggest ransomware threat this year, since 80% of the ransomware lookups was caused by Cerber, while this number is only 44.2% if we look at the whole world. Regarding the smaller families, the results are very similar.”

The SophosLabs 2018 Malware Forecast report recaps ransomware and other cyber security trends based on data collected from Sophos customer computers worldwide from 1 April to 3 October 2017.

One key finding shows that while ransomware predominately attacked Windows systems in the last six months, Android, Linux and MacOS platforms were not immune.

“Ransomware has become platform-agnostic. Ransomware mostly targets Windows computers, but this year, SophosLabs saw an increased amount of crypto-attacks on different devices and operating systems used by our customers worldwide,” says Palotay.

She notes that for the first time Sophos saw ransomware with worm-like characteristics, which contributed to the rapid expansion of WannaCry.

“This ransomware took advantage of a known Windows vulnerability to infect and spread to computers, making it hard to control.

“Even though our customers are protected against it and WannaCry has tapered off, we still see the threat because of its inherent nature to keep scanning and attacking computers. We’re expecting cyber criminals to build upon this ability to replicate as seen in WannaCry and NotPetya, and this is already evident with Bad Rabbit ransomware, which shows many similarities to NotPetya.”

Millions of Cyber Attacks Launched on Nigeria, Others- Reports

There were 3.8 million malware attacks and 16.8 million Potentially Unwanted Applications (PUA) detections over a 7-month period in Nigeria, according to Kaspersky security solutions.

Millions of Cyber Attacks Launched on Nigeria, Others- Reports

Elsewhere in South Africa, there were almost 10 million malware attacks and a staggering 43 million PUA detections, showing the growing desperation of the attacks.

The company reported on 28 million malware attacks in 2020 and 102 million detections of potentially unwanted programs (pornware, adware etc.) accounted for by the beginning of August 2020.

These numbers show that it’s not only the malware that attacks users but also the “grey zone” programmes that grow in popularity and disturb their experiences, while users might not even know it is there.

Potentially unwanted applications (PUAs) are programmes that are usually not considered to be malicious by themselves.

However, they are generally influencing user experience in a negative way. For instance, adware fills user device with ads; aggressive monetising software propagates unrequested paid offers; downloaders may download even more various applications on the device, sometimes malicious ones.

calculating interim results of threat landscape activity in African countries, Kaspersky researchers noticed that PUAs attack users almost four times more often than traditional malware.

They also eventually reach more users: for instance, while in South Africa, the malware would attack 415,000 users in 7-months of 2020, the figure for PUA would be 736,000.

“The reason why ‘grey zone’ software is growing in popularity is that it is harder to notice at first and that if the programme is detected, its creators won’t be considered to be cybercriminals. The problem with them is that users are not always aware they consented to the installation of such programmes on their device and that in some cases, such programmes are exploited or used as a disguise for malware downloads,” said Denis Parinov, a security researcher at Kaspersky.

By taking a closer look at PUA, it becomes apparent that they are not only more widespread but also more potent than traditional malware.

Evaluating results over the same 7-month period in Nigeria, there were 3.8 million malware attacks and 16.8 million PUA detections – which is four times as much.

Kenyan and South African threat landscapes have been more intense. In South Africa, there were almost 10 million malware attacks and a staggering 43 million PUA detections.

Kenyan users faced even more malware attacks – around 14 million, and 41 million PUA appearances, Kaspersky said.

Tech Giants Strike Deal with Advertisers over Hate Speech

Published

Kindly share this post

Web giants including Facebook have struck a deal with advertisers on how to identify harmful content such as hate speech, after an impasse over the issue which led to boycotts of the platform.

Tech Giants Strike Deal with Advertisers over Hate Speech

The agreement — which also included Twitter and YouTube — laid out for the first time a common set of definitions for hateful statements online.

In July, hundreds of advertisers including big-name consumer brands suspended advertising with Facebook as part of the #StopHateForProfit campaign, saying the social-media titan should do more to stamp out hatred and misinformation on its platform.

And earlier this month a group of celebrities — including Kim Kardashian, Leonardo DiCaprio and Katy Perry — stopped using Facebook and Instagram for 24 hours, to push a similar message.

The World Federation of Advertisers (WFA) said in a statement Wednesday: “Facebook, YouTube and Twitter, in collaboration with marketers and agencies through the Global Alliance for Responsible Media have agreed to adopt a common set of definitions for hate speech and other harmful content and to collaborate with a view to monitoring industry efforts to improve in this critical area.”

The alliance was founded by the WFA and includes other major trade bodies.

According to the WFA, key areas of agreement included applying the alliance’s common definitions of harmful content; developing reporting standards for such content; establishing independent oversight; and rolling out tools for keeping advertisements away from harmful content.

The WFA said that properly defining online hate speech would remove the current problem of different platforms using their own definitions, which it said made it difficult for companies to decide where to put their ads.

“As funders of the online ecosystem, advertisers have a critical role to play in driving positive change and we are pleased to have reached agreement with the platforms on an action plan and timeline in order to make the necessary improvements,” said Stephan Loerke, chief executive of the WFA.

Luis Di Como, executive vice-president of global media at Unilever, a major advertiser, sounded a note of cautious optimism.

He said: “The issues within the online ecosystem are complicated, and whilst change doesn’t happen overnight, today marks an important step in the right direction.”

Speaking in July, Facebook’s founder and chief executive Mark Zuckerberg said he remained adamant that the company did not want hate speech on the social network.

On Wednesday, the company’s vice-president for global marketing solutions, Carolyn Everson, said the agreement gave all parties “a unified language to move forward on the fight against hate online.”
