The Petya ransomeware attack that has been spreading around the world since 27 June my be the worst of its kind and infections are starting to show up in South Africa.
The Petya ransomware attack that has been spreading across the world since yesterday (27 June) may prove to be the worst of its kind yet experienced. South Africa has remained relatively unscathed, but infections are beginning here.
ESET researchers have located the point from which this global epidemic has all started. Attackers have successfully compromised the accounting software M.E.Doc, popular across various industries in Ukraine, including financial institutions. Several of them executed a trojanized update of M.E.Doc, which allowed attackers to launch the massive ransomware campaign today which spread across the whole country and to the whole world. M.E.Doc has today released a warning on their website: http://www.me-doc.com.ua/vnimaniyu-polzovateley
Numerous reports are coming out on social media about a new ransomware attack in Ukraine, which could be related to the Petya family, which is currently detected by ESET as Win32/Diskcoder.C Trojan. If it successfully infects the MBR, it will encrypt the whole drive itself. Otherwise, it encrypts all files, like Mischa.
For spreading, it appears to be using a combination of the SMB exploit (EternalBlue) used by WannaCryptor for getting inside the network, then spreading through PsExec for spreading within the network.
This dangerous combination may be the reason why this outbreak has spread globally and rapidly, even after the previous outbreaks have generated media headlines and hopefully most vulnerabilities have been patched. It only takes one unpatched computer to get inside the network, and the malware can get administrator rights and spread to other computers.
The journalist Christian Borys, for example, tweeted that the cyberattack has “allegedly hit” banks, power grid and postal companies, among others. Moreover, it appears that the government has also come under attack. Borys has also tweeted an image put up on Facebook by Ukraine’s deputy prime minister, Pavlo Rozenko, which shows a computer apparently being encrypted.
The National Bank of Ukraine has also put out a message on its website warning other banks of the ransomware attack. It stated: “Currently, the financial sector strengthened security measures and counter hacker attacks all financial market participants.”
Forbes said that while there appear to be similarities with WannaCryptor – with others describing it as WannaCry-esque – it is likely to be a variant of Petya.
An image, similar to the one witnessed by WannaCryptor victims, reportedly showing the ransomware message is making the rounds online, with one from Group-IB showing the following message (paraphrased):
“If you see this text, then your files are no longer accessible, because they have been encrypted … We guarantee that you can recover all your files safely and easily. All you need to do is submit the payment [$300 bitcoins] and purchase the decryption key.”
However, a spokesman said that “there is no effect on power supplies”, although it may be too early to ascertain this.
It appears that the ransomware attack is not specific to Ukraine. The Independent said that Spain and India may also have been affected, as well as the Danish shipping company Maersk and the British advertising company WPP.
On the latter’s homepage, the following message reads: “The WPP web site is currently unavailable due to important routine maintenance normal service will resume shortly.
“We apologise for any inconvenience this may cause. In the meantime if you would like to contact WPP, please email the site Editor at the following address …”
WPP has since confirmed on Twitter that it has been the victim of an attack: “IT systems in several WPP companies have been affected by a suspected cyberattack. We are taking appropriate measures & will update asap.”
There are also reports that payments are being made in response to the attack, at the BTC address linked here.
For more on Petya, check out this insightful piece from 2016, which notes of the crypto-ransomware:
“Petya took an approach different from that of other crypto-ransomware. Instead of encrypting files individually, it aimed at the file system.
“The target is the victim’s master boot record (MBR), which is responsible for loading the operating system right after system boot.”
In order to prevent this kind of threat, we recommend that you always have your systems fully patched, that you use a proper security solution and that you set up network segmentation, which might help prevent spreading within the network.

Santam Safety Ideas
Start-up businesses that have a FinTech or InsurTech business venture brewing are called to enter the third annual Santam Safety Ideas competition. Safety solutions or InsurTech ventures that are ready for piloting could win up to R150 000 worth of incubation support and R200 000 in seed funding.
The Safety Ideas competition was launched two years ago in partnership with LaunchLab, Stellenbosch University’s startup incubator that facilitates valuable connections for corporates and startups sourced from the startup ecosystem and partner universities in South Africa. The previous winners are Herman Bester and Anton Swanevelder, co-founders of MyLifeLine – a wearable panic device that won the competition last year; and Ntsako Mgiba and Ntandoyenkosi Shezi, co-founders of Jonga – a cost-effective security system for low income families, which won the competition in 2017.

Fortnite fixes hackers’ hole
Epic Games has repaired a vulnerability that exposed Fortnite, the world’s most popular game of the moment, to hackers. The hole, which was left in Epic’s web infrastructure, allowed hackers to target players with email that appeared to come from Epic Games, but would have led them to a phishing site, where their log-in details would have been stolen.
Researchers at cyber security solutions provider Check Point Software alerted Epic to vulnerabilities that could have affected any player of the hugely popular online battle game.
Fortnite has nearly 80 million players worldwide. The game is popular on all gaming platforms, including Android, iOS, PC via Microsoft Windows and consoles such as Xbox One and PlayStation 4. In addition to casual players, Fortnite is used by professional gamers who stream their sessions online, and is popular with e-sports enthusiasts.
If exploited, the vulnerability would have given an attacker full access to a user’s account and their personal information as well as enabling them to purchase virtual in-game currency using the victim’s payment card details. The vulnerability would also have allowed for a massive invasion of privacy, as an attacker could listen to in-game chatter as well as surrounding sounds and conversations within the victim’s home or other location of play.
While Fortnite players had previously been targeted by scams that deceived them into logging into fake websites that promised to generate Fortnite’s ‘V-Buck’ in-game currency, these new vulnerabilities could have been exploited without the player handing over any login details.
