Sweden is on edge over potential Russian sabotage, while a new Cicada ransomware variant is targeting VMware ESXi systems. Halliburton’s confirmation of a major data breach and the FBI’s alert on North Korean social engineering in the crypto sector only add to the urgency. Dive into these stories and more to discover what they mean for the future of cybersecurity.
Critical RCE flaw affects Progress Software’s WhatsUp Gold
Censys has published an advisory on a remote code execution vulnerability affecting Progress Software’s WhatsUp Gold network monitoring and management solution, SecurityWeek reports. The researchers explain, “The vulnerability exists in the GetFileWithoutZip functionality of WhatsUp Gold. An attacker can send a crafted request with directory traversal payloads to upload files to arbitrary locations on the server. By uploading malicious files, the attacker can achieve remote code execution.” Several proof-of-concept exploits have been published on GitHub, and users are urged to update to version 2023.1.3 as soon as possible.

Transport for London suffers cyberattack
The local government body responsible for most of the transport system in Greater London is currently dealing with a cyberattack, but representatives state that there is no evidence that customer information was compromised during the incident. The BBC has stated that the attack mainly impacted the transport provider’s backroom systems at the corporate headquarters. (BBC News)
Sweden warns of heightened risk of Russian sabotage
Security companies in Sweden have reported an increase in sabotage attempts, such as flying mapping drones over defense facilities, and other “more aggressive” espionage, cyber-attacks and misinformation activities. This appears to be connected to the fact that Sweden is supporting Ukraine, and has joined NATO, and evidence of increased aggression in espionage as well as disinformation about the reliability of Swedish military products has been seen in large and small companies involved in the manufacture of weapons and related technologies.

New Cicada variant preys on VMWare ESXi systems
This new ransomware-as-a-service group, named Cicada3301 is already quite busy, with 23 victims since mid-June, according to its leak site. Its ransomware is written in Rust and targets Windows and Linux/ESXi hosts. Researchers at Truesec analyzed a variant that targets VMware ESXi systems, and said it appears to be a version of the Windows malware. They added that “the Cicada3301 ransomware has several interesting similarities to the ALPHV ransomware.” (Security Affairs)
SlowTempest espionage campaign unfolds within China
Researchers at Securonix are tracking what is being called a highly coordinated espionage operation that is targeting people and organizations within China and appears to be the work of an organization with deep knowledge of Chinese language and culture. The goal of the attackers appears to be espionage, persistent access, and potential sabotage, with the end goal being to infiltrate government or high-profile business sectors. The researchers cannot say where the attacks are ultimately coming from or who is behind them, but they note that the sophisticated attack has been designed not just to gain access to their victims, but to maintain it in order to achieve broader strategic objectives, potentially aligned with state-sponsored activities.

Threat actors have poisoned GlobalProtect VPN software to deliver WikiLoader
Hackers have been targeting VPNs like GlobalProtect to inject malware and steal sensitive data, compromising private networks without detection. Cybersecurity researchers at Palo Alto Networks discovered that threat actors have poisoned GlobalProtect VPN software to deliver WikiLoader, a sophisticated malware loader. Active since late 2022, WikiLoader primarily spreads via phishing but recently shifted to SEO poisoning, leading users to fake installer pages. The malware uses complex evasion techniques, including DLL sideloading and shellcode decryption, making detection difficult. WikiLoader’s operators utilize compromised WordPress sites and MQTT brokers for command and control. The malware creates persistence through scheduled tasks and hides in over 400 files within a malicious archive. Despite the malware’s complexity, it was detected by Cortex XDR through behavioral indicators. Mitigations include enhanced SEO poisoning detection, robust endpoint protection, and application whitelisting. (Cyber Security News)
Voldemort malware delivered via social engineering
Proofpoint describes a social engineering campaign that’s impersonating tax authorities in Europe, Asia, and the US in order to deliver a custom strain of malware dubbed “Voldemort.” The researchers explain, “The attack chain comprises multiple techniques currently popular within the threat landscape as well as uncommon methods for command and control (C2) like the use of Google Sheets. Its combination of the tactics, techniques, and procedures (TTPs), lure themes impersonating government agencies of various countries, and odd file naming and passwords like ‘test’ are notable. Researchers initially suspected the activity may be a red team, however the large volume of messages and analysis of the malware very quickly indicated it was a threat actor.” The researchers don’t attribute the activity to any particular threat actor, but they believe the campaign’s goal is cyberespionage.

Halliburton confirms data stolen in cyberattack
Following up on a story from last week on Cyber Security Headlines, the U.S. oil service giant confirmed Tuesday that corporate data was stolen from its computer systems during a ransomware attack it suffered in August. Halliburton stopped short of confirming a ransomware extortion scheme but said significant portions of its IT systems were disrupted. The company said it engaged law enforcement to help identify exactly what data was stolen and who they will need to notify. The company’s acknowledgement comes on the heels of CISA, the FBI, and HHS blaming the RansomHub gang for the attack. (SecurityWeek)
FBI warns crypto firms of aggressive North Korean social engineering
On Tuesday, the FBI warned that North Korean hacking groups are aggressively targeting crypto company employees in sophisticated social engineering attacks. After the threat actors identify specific DeFi and crypto businesses, they then target employees with offers of new employment or investment opportunities to deploy crypto-stealing malware. The communications use fluent English and leverage detailed personal information to boost credibility and appeal. The FBI added that the threat actors are also well-versed in technical aspects of cryptocurrency. The FBI provided a list of indicators associated with North Korean social engineering activity and best practices for companies to lower the risk of compromise. (Bleeping Computer and The Record)
North Korean social engineering attacks target the cryptocurrency sector
The US Federal Bureau of Investigation (FBI) has issued an advisory on North Korean social engineering campaigns targeting employees in the cryptocurrency industry. The Bureau notes, “North Korean malicious cyber actors conducted research on a variety of targets connected to cryptocurrency exchange-traded funds (ETFs) over the last several months. This research included pre-operational preparations suggesting North Korean actors may attempt malicious cyber activities against companies associated with cryptocurrency ETFs or other cryptocurrency-related financial products. For companies active in or associated with the cryptocurrency sector, the FBI emphasizes North Korea employs sophisticated tactics to steal cryptocurrency funds and is a persistent threat to organizations with access to large quantities of cryptocurrency-related assets or products.” (FBI)
Iran paid at least $3 million in ransom following attack on banking system
POLITICO reports that Iran paid at least $3 million in ransom last month to extortionists who threatened to leak information stolen from up to 20 Iranian banks. The hacking group “IRLeaks” claimed to have stolen personal and financial data belonging to millions of Iranians. Iran hasn’t acknowledged the incident, but the country’s supreme leader said in the wake of the attack that the US and Israel are attempting “to spread psychological warfare to push us into political and economic retreat and achieve its objectives.” POLITICO cites sources as saying that IRLeaks is likely a financially motivated group, unaffiliated with a nation-state.

Indictments follow swatting attack on CISA boss Easterly
Following up on the story from last December in which a swatting attack was placed on the home of Jen Easterly, two individuals have now been identified as instigating this attack along with about 100 other threats against U.S. politicians, members of Congress and senior Federal law enforcement officials. The two individuals, both in their 20s, are from Romania and Serbia. (The Record)
Cisco issues patches for smart licensing utility
These patches deal with two issues regarding the company’s Smart Licensing Utility. The first would allow unauthenticated attackers to access sensitive information or to log in as administrators. It exists due to “an undocumented static user credential for an administrative account present in the Utility.” The second issue is due to “excessive verbosity in a debug log file, which could allow an attacker to send a crafted HTTP request and obtain log files containing sensitive data, including credentials.” Since there are no workarounds available, Cisco recommends migrating to Smart License Utility version 2.3.0.
