This ransomware was first spotted to be impersonating the Google Software Update program, and on torrent sites, injected in installers wrapping pirated versions of popular macOS software such as Little Snitch, Ableton Live, and Mixed in key. EvilQuest ransomware is discovered to encrypt macOS systems, installs a keylogger and a reverse shell for full control over infected host, and exfiltrates files that contain valuable information (keys to cryptocurrency wallets, code-signing certificates, and many more) with a variety of extensions (eg .pdf, .doc, .jpg, .txt, .pages, .wallet, .zip, etc).
According to Cisco, different categories of vulnerabilities were discovered from different Cisco routers. This vulnerabilities ranges from static default credential, Management interface remote command execution, authentication bypass, arbitrary code execution, and privilege escalation.
Researchers discovered that attackers can access organizations ‘networks through remote access systems to carry out ransomware attack. This is performed through the remote desktop protocol (RDP) and virtual private networks (VPN). The impact of these attacks can be severe on business operations because data are stolen and sold. Also, the recovery from this attacks is very costly to investigate and remediate the compromised network, and restore encrypted files from backup.
Researchers discovered multiple vulnerabilities in the web-based management interface of Cisco Small Business RV320 and RV325 Series Routers and Cisco Small Business RV016, RV042, and RV082 Routers. This vulnerabilities could allow an authenticated, remote attacker with administrative privileges to execute arbitrary commands on an affected device.
Recently, a group of security researchers discovered a new vulnerability named ReVoLTE attack. This vulnerability is due to mobile operators often utilizing similarly encryption key to obtain multiple 4G voice calls that takes place through similarly base station. This vulnerability could allow a malicious attacker to manipulate encrypted content of a recorded Volte call so as to eavesdrop the conversation.
Researchers has discovered critical security risk with Tecno Android phones which has a pre-installed malware called Triada. Malware which signed users up to subscription services without their permission was discovered on thousands of Tecno mobile phones sold in Africa. Anti-fraud firm Upstream found the malicious code on Tecno handsets sold in Ethiopia, Cameroon, Egypt, Ghana and South Africa.
An SQL injection is a technique that attackers apply to insert SQL query into input fields to then be processed by the underlying SQL database. These weaknesses are then able to be abused when entry forms allow user-generated SQL statements to query the database directly. The attack results in the unauthorized viewing of user lists, the deletion of database entries and stealing of data.
The recent Classification of Nigeria, Kenya and Egypt by Kaspersky lab as easiest Cyberattack target in Africa with about Five Hundred and seventy-seven (577) attempted malware attacks hourly, is a serious wake up call to the government and the stakeholders in the Cybersecurity industry. This was disclosed in the company’s second quarter Spam and phishing 2020 report.
Reports revealed recent compromises of U.S. government agencies, critical infrastructure entities, and private sector organizations by an advanced persistent threat (APT) actor which began at least since March 2020. It is expected that removing this threat actor from compromised environments will be highly complex and challenging for organizations hence the need to take proactive actions in the protection of government critical national information infrastructures. The cyber-security firm that identified the large-scale hacking of US government agencies says it "genuinely impacted" around 50 organisations. The US Treasury and departments of homeland security, state and defence are known to have been targeted. Russian Intelligence has been accused by the US for the cyber intrusion. Several other organisations around the world are understood to have been targeted by hackers using the same network management software.
After conducting investigations into the Advanced Persistent Threat Compromise of Government Critical National Infrastructure, and Private Sector Organizations Infrastructures, SolarWinds have released an updated advisory for the Sunburst and the SuperNova backdoor that was discovered while investigating the recent SolarWinds Orion supply-chain attack. It was discovered that the SuperNova backdoor was likely used by a separate threat actor. Several teams of researchers have mentioned the existence of two second-stage payloads after the initial disclosure of the SolarWinds attacks.
Phishing attacks are the most common and effective cyber security threat to individuals, businesses and organizations. Phishing is the delivery mechanism of choice for ransomware and other malware and it is a critical problem that every organization must address through a variety of means. Most phishing messages indicate immediate action is needed to avoid an unwanted time-sensitive consequence. It is important to be suspicious of all requests, and review messages carefully to determine if the message may be a phishing scam.
