Based on analysis by Visa Payment Fraud Disruption, the skimmer appears to be more advanced, loading dynamically and using an XOR cipher for obfuscation.

After receiving many tech support calls, the computer networks were shut down to prevent further spread of the ransomware, which led to a cecission in border crossings until systems were up again. The ransomware used in this attack is Netwalker ransomware, that left a ransom note demanding initalling $2 million, however when this wasn’t paid in the first week, the ransom increased to $4 million.<br/> <b>Recommendation:</b> Ransomware can potentially be blocked by using endpoint protection solutions (HIDS). Always keep your important files backed up following the 3-2-1 rule: have at least 3 different copies, on 2 different mediums, with 1 off-site. In the case of ransomware infection, the affected system must be wiped and reformatted. Other devices on the network should be checked for similar infections. Always check for a decryptor before considering payment; avoid payment at all costs. Ransomware should be reported to law enforcement agencies who are doing their best to track these actors and prevent ransom from being a profitable business for cyber criminals.<br/> <b>MITRE ATT&amp;CK: </b> <a href="https://ui.threatstream.com/ttp/2402531">[MITRE ATT&amp;CK] Data Encrypted for Impact - T1486</a><br/> <b>Tags:</b> Argentina, Government, Netwalker, Ransomware</p> <h3 id="article-3" style="margin-bottom:0;"><a href="https://www.cybereason.com/blog/no-rest-for-the-wicked-evilnum-unleashes-pyvil-rat" target="_blank">No Rest for the Wicked: Evilnum Unleashes PyVil RAT</a></h3> <p>(published: September 3, 2020)</p> <p>Researchers on the Cybereason Nocturnus team have published their research tracking the threat actor group known as Evilnum, and an ongoing change in their tooling and attack procedures. This includes a new Remote Access Trojan (RAT), written in python that they have begun to use. The actor group attacks targets in the financial services sector using highly targeted spearphishing. The phishing lures leverage "Know Your Customer" (KYC) methods to increase perceived legitimacy and trick the targets to click on a malicious LNK file that uses a small javascript dropper to achieve initial infection. The dropper subsequently downloads a secondary payload responsible for retrieving and installing the final PyVil RAT executable.

First observed in the middle of August, Radware have identified several extortion requests from threat actors posing as well-known Advanced Persistent Threat (APT) groups including Fancy Bear, Lazarus Group and Armada Collective. Victims are initially contacted with an email including target specific IP addresses and Autonomous System Numbers (ASNs) of servers or services that will be targeted unless the victim pays a ransom. The ransom fee is generally set around 10 BTC (approximately $113,000), however, ransoms of up to 20 BTC have been reported.<br/> <b>Recommendation:</b> Denial-of-service attacks can potentially cost your company loss in revenue because severe attacks can shut down online services for extended periods of time.

Microsoft Defender will still detect malicious files downloaded with MpCmdRun.exe but it is currently unclear if other AV software will allow this program to bypass their detections.<br/> <b>Recommendation:</b> Your company should have patch-maintenance policies in place to expect Microsoft’s Patch Tuesday every month.

The use of Telegram allows the skimmers, which are designed to be executed on checkout pages on web stores, to blend the exfiltration traffic in what appears to be legitimate traffic. Also the use of a legitimate service, makes the exfiltration harder to block, to take down, and not requiring the threat actor to run their infrastructure.<br/> <b>Recommendation:</b> Protecting against credit card skimmers on the client side is a hard task. A TLS interceptor can be used to block traffic to Telegram’s bot API (https://api.telegram.org/bot*). eCommerce site owners must take every step necessary to secure their data and safeguard their payment card information. A bad experience at a retailer site may mean the loss of revenue as impacted users take their money elsewhere. Ensure that your company's firewall blocks all entry points for unauthorized users, and maintain records of how normal traffic appears on your network. Therefore, it will be easier to spot unusual traffic and connections to and from your network to potentially identify malicious activity. Furthermore, ensure that your employees are educated about the risks of opening attachments, particularly from unknown senders and any attachment that requests macros be enabled.Websites, much like personal workstations, require constant maintenance and upkeep to adapt to the latest threats.

Subsequently, in July 2020 a new phishing campaign that targeted Tibetan dissidents was identified delivering the same strain of Sepulcher malware.
