Threat actors affiliated with a ransomware strain known as Play are leveraging a never-before-seen exploit chain that bypasses blocking rules for ProxyNotShell flaws in Microsoft Exchange Server to achieve remote code execution (RCE) through Outlook Web Access (OWA). “The new exploit method bypasses URL rewrite mitigations for the Autodiscover endpoint,” CrowdStrike researchers Brian Pitchford, Erik […]
An ongoing analysis of the KmsdBot botnet has raised the possibility that it’s a DDoS-for-hire service offered to other threat actors. This is based on the different industries and geographies that were attacked, web infrastructure company Akamai said. Among the notable targets included FiveM and RedM, which are game modifications for Grand Theft Auto V […]
The operators of the Glupteba botnet resurfaced in June 2022 as part of a renewed and “upscaled” campaign, months after Google disrupted the malicious activity. The ongoing attack is suggestive of the malware’s resilience in the face of takedowns, cybersecurity company Nozomi Networks said in a write-up. “In addition, there was a tenfold increase in […]
Meta Platforms disclosed that it took down no less than 200 covert influence operations since 2017 spanning roughly 70 countries across 42 languages. The social media conglomerate also took steps to disable accounts and block infrastructure operated by spyware vendors, including in China, Russia, Israel, the U.S. and India, that targeted individuals in about 200 […]
Microsoft has revised the severity of a security vulnerability it originally patched in September 2022, upgrading it to “Critical” after it emerged that it could be exploited to achieve remote code execution. Tracked as CVE-2022-37958 (CVSS score: 8.1), the flaw was previously described as an information disclosure vulnerability in SPNEGO Extended Negotiation (NEGOEX) Security Mechanism. […]
The U.S. Department of Justice (DoJ) on Wednesday announced the seizure of 48 domains that offered services to conduct distributed denial-of-service (DDoS) attacks on behalf of other threat actors, effectively lowering the barrier to entry for malicious activity. It also charged six suspects – Jeremiah Sam Evans Miller (23), Angel Manuel Colon Jr. (37), Shamar […]
Phishing campaigns involving the Qakbot malware are using Scalable Vector Graphics (SVG) images embedded in HTML email attachments. The new distribution method was spotted by Cisco Talos, which said it identified fraudulent email messages featuring HTML attachments with encoded SVG images that incorporate HTML script tags. HTML smuggling is a technique that relies on using […]
Cybersecurity researchers have published the inner workings of a new wiper called Azov Ransomware that’s deliberately designed to corrupt data and “inflict impeccable damage” to compromised systems. Distributed through another malware loader known as SmokeLoader, the malware has been described as an “effective, fast, and unfortunately unrecoverable data wiper,” by Israeli cybersecurity company Check Point. […]
A cryptocurrency mining attack targeting the Linux operating system also involved the use of an open source remote access trojan (RAT) dubbed CHAOS. The threat, which was spotted by Trend Micro in November 2022, remains virtually unchanged in all other aspects, including when it comes to terminating competing malware, security software, and deploying the Monero […]
The U.S. Department of Health and Human Services (HHS) has cautioned of ongoing Royal ransomware attacks targeting healthcare entities in the country. “While most of the known ransomware operators have performed Ransomware-as-a-Service, Royal appears to be a private group without any affiliates while maintaining financial motivation as their goal,” the agency’s Health Sector Cybersecurity Coordination […]
Travel agencies have emerged as the target of a hack-for-hire group dubbed Evilnum as part of a broader campaign aimed at legal and financial investment institutions in the Middle East and Europe. The attacks, which took place during 2020 and 2021 and likely went as far back as 2015, involved a revamped variant of a […]
Cybersecurity researchers have shed light on a darknet marketplace called InTheBox that’s designed to specifically cater to mobile malware operators. The actor behind the criminal storefront, believed to be available since at least January 2020, has been offering over 400 custom web injects grouped by geography that can be purchased by other adversaries looking to […]
A persistent intrusion campaign has set its eyes on telecommunications and business process outsourcing (BPO) companies at lease since June 2022. “The end objective of this campaign appears to be to gain access to mobile carrier networks and, as evidenced in two investigations, perform SIM swapping activity,” CrowdStrike researcher Tim Parisi said in an analysis […]
A version of an open source ransomware toolkit called Cryptonite has been observed in the wild with wiper capabilities due to its “weak architecture and programming.” Cryptonite, unlike other ransomware strains, is not available for sale on the cybercriminal underground, and was instead offered for free by an actor named CYBERDEVILZ until recently through a […]
A new data wiper malware called CryWiper has been found targeting Russian government agencies, including mayor’s offices and courts. “Although it disguises itself as a ransomware and extorts money from the victim for ‘decrypting’ data, [it] does not actually encrypt, but purposefully destroys data in the affected system,” Kaspersky researchers Fedor Sinitsyn and Janis Zinchenko […]
Cybersecurity researchers have discovered a security vulnerability that exposes cars from Honda, Nissan, Infiniti, and Acura to remote attacks through a connected vehicle service provided by SiriusXM. The issue could be exploited to unlock, start, locate, and honk any car in an unauthorized manner just by knowing the vehicle’s vehicle identification number (VIN), researcher Sam […]
Medibank on Thursday confirmed that the threat actors behind the devastating cyber attack have posted another dump of data stolen from its systems on the dark web after its refusal to pay a ransom. “We are in the process of analyzing the data, but the data released appears to be the data we believed the […]
More than 300,000 users across 71 countries have been victimized by a new Android threat campaign called the Schoolyard Bully Trojan. Mainly designed to steal Facebook credentials, the malware is camouflaged as legitimate education-themed applications to lure unsuspecting users into downloading them. The apps, which were available for download from the official Google Play Store, […]
An ongoing analysis into an up-and-coming cryptocurrency mining botnet known as KmsdBot has led to it being accidentally taken down. KmsdBot, as christened by the Akamai Security Intelligence Response Team (SIRT), came to light mid-November 2022 for its ability to brute-force systems with weak SSH credentials. The botnet strikes both Windows and Linux devices spanning […]
Popular password management service LastPass said it’s investigating a second security incident that involved attackers accessing some of its customer information. “We recently detected unusual activity within a third-party cloud storage service, which is currently shared by both LastPass and its affiliate, GoTo,” LastPass CEO Karim Toubba said. GoTo, formerly called LogMeIn, acquired LastPass in […]
The French data protection watchdog on Tuesday fined electricity provider Électricité de France (EDF) €600,000 for violating the European Union General Data Protection Regulation (GDPR) requirements. The Commission nationale de l’informatique et des libertés (CNIL) said the electric utility breached European regulation by storing the passwords for over 25,800 accounts by hashing them using the […]
