Threat actors have been discovered distributing a new credential stealer written in AutoHotkey (AHK) scripting language as part of an ongoing campaign that started early 2020. Customers of financial institutions in the US and Canada are among the primary targets for credential exfiltration, with a specific focus on banks such as Scotiabank, Royal Bank of Canada, HSBC, Alterna Bank, Capital One, Manulife, and EQ Bank. Also included in the list is an Indian banking firm ICICI Bank. AutoHotkey  is an open-source custom scripting language for Microsoft Windows aimed at providing easy hotkeys for macro-creation and software automation that allows users to automate repetitive tasks in any Windows application. The multi-stage infection chain commences with a malware-laced Excel file that's embedded with a Visual Basic for Applications (VBA)  AutoOpen  macro, which is subsequently used to drop and execute the downloader client script ("adb.ahk") via a legitimate portable AHK...

An authentication bypass vulnerability in the SolarWinds Orion software may have been leveraged by adversaries as a zero-day to deploy the SUPERNOVA malware in target environments. According to an  advisory  published yesterday by the CERT Coordination Center, the SolarWinds Orion API that's used to interface with all other Orion system monitoring and management products suffers from a security flaw (CVE-2020-10148) that could allow a remote attacker to execute unauthenticated API commands, thus resulting in a compromise of the SolarWinds instance. "The authentication of the API can be bypassed by including specific parameters in the  Request.PathInfo  portion of a URI request to the API, which could allow an attacker to execute unauthenticated API commands," the advisory states. "In particular, if an attacker appends a PathInfo parameter of 'WebResource.adx,' 'ScriptResource.adx,' 'i18n.ashx,' or 'Skipi18n' to a request to a Solar...

21 people have been arrested across the UK as part of a nationwide cyber crackdown targeting customers of WeLeakInfo[.]com, a now-defunct online service that had been previously selling access to data hacked from other websites. The suspects used stolen personal credentials to commit further cyber and fraud offences, the UK National Crime Agency (NCA)  said . Of the 21 arrested — all men aged between 18 and 38 — nine have been detained on suspicion of Computer Misuse Act offences, nine for Fraud offences, and three are under investigation for both. The NCA also seized over £41,000 in bitcoin from the arrested individuals. Earlier this  January , the US Federal Bureau of Investigation (FBI), the NCA, the Netherlands National Police Corps, the German Bundeskriminalamt, and the Police Service of Northern Ireland jointly  seized the domain  of WeLeakInfo.com. Launched in 2017, the service provided its users a search engine to access the personal i...

New evidence amidst the ongoing probe into the  espionage campaign  targeting SolarWinds has uncovered an unsuccessful attempt to compromise cybersecurity firm Crowdstrike and access the company's email. The hacking endeavor was reported to the company by Microsoft's Threat Intelligence Center on December 15, which identified a third-party reseller's Microsoft Azure account to be making "abnormal calls" to Microsoft cloud APIs during a 17-hour period several months ago. The undisclosed affected reseller's Azure account handles Microsoft Office licensing for its Azure customers, including CrowdStrike. Although there was an attempt by unidentified threat actors to read the emails, it was ultimately foiled as the firm does not use Microsoft's Office 365 email service, CrowdStrike  said . The incident comes in the wake of the  supply chain attack  of SolarWinds revealed earlier this month, resulting in the deployment of a covert backdoor (aka "Sunbu...

Citrix has issued an emergency advisory warning its customers of a security issue affecting its NetScaler application delivery controller (ADC) devices that attackers are abusing to launch amplified distributed denial-of-service (DDoS) attacks against several targets . "An attacker or bots can overwhelm the Citrix ADC [Datagram Transport Layer Security] network throughput, potentially leading to outbound bandwidth exhaustion," the company  noted . "The effect of this attack appears to be more prominent on connections with limited bandwidth." ADCs are purpose-built  networking appliances  whose function is to improve the performance, security, and availability of applications delivered over the web to end-users. The desktop virtualization and networking service provider said it's monitoring the incident and is continuing to investigate its impact on Citrix ADC, adding "the attack is limited to a small number of customers around the world." The iss...

Google's Project Zero team has made public details of an improperly patched zero-day security vulnerability in Windows print spooler API that could be leveraged by a bad actor to execute arbitrary code. Details of the unpatched flaw were revealed publicly after Microsoft failed to rectify it within 90 days of responsible disclosure on September 24. Originally tracked as  CVE-2020-0986 , the flaw concerns an elevation of privilege exploit in the GDI Print /  Print Spooler  API ("splwow64.exe") that was reported to Microsoft by an anonymous user working with Trend Micro's Zero Day Initiative (ZDI) back in late December 2019. But with no patch in sight for about six months, ZDI ended up posting a public  advisory  as a zero-day on May 19 earlier this year, after which it was  exploited  in the wild in a campaign dubbed " Operation PowerFall " against an unnamed South Korean company. "splwow64.exe" is a Windows core system binary that allows 32-b...

Threat actors such as the notorious Lazarus group are continuing to tap into the ongoing COVID-19 vaccine research to steal sensitive information to speed up their countries' vaccine-development efforts. Cybersecurity firm Kaspersky  detailed  two incidents at a pharmaceutical company and a government ministry in September and October leveraging different tools and techniques but exhibiting similarities in the post-exploitation process, leading the researchers to connect the two attacks to the North Korean government-linked hackers. "These two incidents reveal the Lazarus group's interest in intelligence related to COVID-19," Seongsu Park, a senior security researcher at Kaspersky, said. "While the group is mostly known for its financial activities, it is a good reminder that it can go after strategic research as well." Kaspersky did not name the targeted entities but said the pharmaceutical firm was breached on September 25, 2020, with the attack again...
