Latest Cyber Attacks in Ukraine Feature Golang-Based

Latest Cyber Attacks in Ukraine Feature Golang-Based "Swiftslice" Wiper Malware

Ukraine has experienced a new wave of cyber aggression from Russia, involving the use of a never-before-seen data eraser referred to as SwiftSlicer. ESET security researchers identified the  as Sandworm, a nation-state actor belonging to Military Unit 74455 of the Main Intelligence Directorate of the Russian Federation (GRU). 

According to ESET's report, the malicious software eliminates any trace of Shadow Copies and recursively erases files located in %CSIDL_SYSTEM%\drivers, %CSIDL_SYSTEM_DRIVE%\Windows\NTDS, as well as other non-system drives.

 In addition, the attack was found to be unique in its ability to generate random byte sequences to overwrite blocks of 4,096 bytes in size. The security firm noted that this malware first made its presence known on January 25, 2023.

Having operated since 2007, Sandworm is renowned for the use of various malicious tools, including BlackEnergy, GreyEnergy, Industroyer, NotPetya, Olympic Destroyer, Exaramel, and Cyclops Blink

In particular, the malware was aggressively deployed against Ukrainian infrastructures in 2022, with malicious code like WhisperGate, HermeticWiper, IsaacWiper, CaddyWiper, Industroyer2, Prestige, and RansomBoggs being observed in multiple networks. 

This illustrates the cyber criminal's aim to inflict as much disruption and destruction as possible.

Fortinet FortiGuard Labs' Geri Revay commented that the significant increase in the use of wiper malware during the Russian-Ukrainian conflict should not be surprising.

In addition, it is not uncommon for nation-state actors to exploit Golang's ability to facilitate the development of malware that can operate across multiple platforms. This has been witnessed in the recent cyber attack against Ukrinform, Ukraine's largest news agency.

On December 7, 2022, the attack reportedly utilized five data-erasing programs - CaddyWiper, ZeroWipe, SDelete, AwfulShred, and BidSwipe - in an attempt to target Windows, Linux, and FreeBSD systems. 

Fortunately, CERT-UA was able to identify the infiltration before any substantial damage could be done, and the group reported on January 17, 2023 that the breach had only resulted in a partial success.

Though Sandworm remains one of the major threats to Ukrainian organizations, they have also been victims of other Russia-backed APT29, COLDRIVER, and Gamaredon operations in the years since the war's beginning. With this in mind, it is crucial for these organizations to stay informed and proactive when it comes to digital security

Iranian Government Faces Another Wave of Cyberattacks from Blackdoordiplomacy Group

Iranian Government Faces Another Wave of Cyberattacks from Blackdoordiplomacy Group

The threat, known as BackdoorDiplomacy, is linked to a new wave of attacks against Iranian government entities between July and December 2022. Palo Alto Networks Unit 42, which monitors the activity under its constellation-themed moniker Playful Taurus, said it had identified. government domains trying to connect to malware infrastructure previously identified as associated with the enemy. 

The Chinese APT group, also known as APT15, KeChang, NICKEL and Vixen Panda, has been conducting cyber espionage campaigns against governments and diplomatic entities in North America, South America, Africa and the Middle East since at least 2010. 

 

In June 2021, the Slovak cyber security company ESET eliminated intrusion by a code group against diplomatic units and telecommunications companies in Africa and the Middle East using an implant called Turian. 

Microsoft then announced in December 2021 that it had seized 2 domains operated by the group in attacks against 29 countries, noting that it used attacks against unpatched systems to compromise Internet web applications such as Microsoft Exchange and SharePoint. 

An attacker is believed to have recently carried out an attack against an unnamed telecommunications company in the Middle East using Quarian, a precursor to Turian that allows remote access to targeted networks. 

Turian "is still in active development and we estimate that it will only be used by Game Taurus actors," Unit 42 said in a report shared with Hacker News, adding that new variants of a backdoor used in Iranian separatist attacks have been found. 

The cybersecurity firm also noted that it had discovered four different Iranian organizations, including the Ministry of Foreign Affairs and the Natural Resources Organization, had contacted the group's classified known command and control (C2) server. 

 

"The ongoing, daily nature of these connections to Playful Taurus' controlled infrastructure suggests a likely compromise of these networks," he said. New versions of the Turian backdoor include additional obfuscation and an updated decryption algorithm used to crack C2 servers. However, the malware itself is generic as it provides basic functions to update the C2 server to connect, execute commands and create reverse shells. 

Diplomatic interest in targeting Iran is said to have a geopolitical reach, as it comes on the back of a 25-year-old comprehensive comprehensive cooperation agreement between China and Iran aimed at promoting economic, military and security cooperation. 

"Playful Taurus continues to develop their tactics and tools," Unit 42 scientists said. "Recent updates on Turian backdoors and new C2 infrastructure suggest that these actors continue to see success in their cyber espionage campagns."

7. Look out for small variations in web addresses or spelling which can be indicate a phishing website.

8. Be aware of who you giving sensitive information to and look for trust-indicating signs like SSL Certificates, green padlock on browser, contact information, and clear return and refund policies.

Educate yourself about common phishing techniques and tactics so that you can better recognize them.

Antivirus and Firewall Prevention

Antivirus software is a program or set of programs that are designed to prevent, detect, and remove malware from a computer or device. 

It typically works by scanning all of the files on a computer or device and identifying those that match known patterns of malware. Once a malicious file is identified, the antivirus software will either remove it or quarantine it to prevent it from causing any harm.

A firewall, on the other hand, is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules and policies. It acts as a barrier between a private internal network and the public Internet. 

The firewall can be hardware-based or software-based, and its main purpose is to block unauthorized access while permitting authorized communication.

Both antivirus software and firewalls can play an important role in preventing cyberattacks by protecting the computer or device from malware and unauthorized access, respectively. 

Together these solutions can offer a more robust defense against cyber threats.

It's important to note that antivirus and Firewalls are prevention mechanism and by themselves are not 100% effective. 

They can be bypassed, or sometimes with new or unknown malware they may not detect it. Keeping the software updated, maintain good computer hygiene and security best practices are important in addition to having a robust firewall and antivirus.

Securing Mobile Devices Information

There are several best practices for securing mobile devices and protecting personal information on mobile apps:

Keep your mobile device's operating system and apps up to date, as these updates often include security patches.

Use a strong and unique password or passphrase to lock your device, and enable two-factor authentication (2FA) when available.

Be cautious of public Wi-Fi networks and avoid connecting to them whenever possible. If you must use a public network, use a virtual private network (VPN) to encrypt your traffic.

Use mobile security app to scan for malware and other security threats on your device.

Be careful about the apps you install and the permissions you grant them. Avoid installing apps from untrusted sources and only give apps the permissions they need to function.

Be aware of phishing scams and other malicious content, never click on suspicious links or enter personal information into a website or app that you are not sure is legitimate.

Regularly back up important data such as contacts and photos to a cloud-based service or computer to ensure that you do not lose them in case your device is lost or stolen.e mindful about the personal information that you share online and on your device, especially sensitive information like financial data, social security numbers, and passwords.
