A U.K. national has pleaded guilty in the U.S. in connection with the July 2020 Twitter attack affecting numerous high-profile accounts and defrauding other users of the platform. Joseph James O'Connor, who also went by the online alias PlugwalkJoe , admitted to "his role in cyberstalking and multiple schemes that involve computer hacking, including the July 2020 hack of Twitter," the U.S. Department of Justice (DoJ) said. The 23-year-old individual was extradited from Spain on April 26 after the Spanish National Court, in February,  approved  the DoJ request to hand over O'Connor to face 14 criminal charges in the U.S. The  massive hack , which took place on July 15, 2020, involved O'Connor and his co-conspirators seizing control of 130 Twitter accounts, including those belonging to Barack Obama, Bill Gates, and Elon Musk, to perpetrate a cryptocurrency scam that netted them $120,000 in a few hours. The attack was made possible by using social engineering te...

The U.S. government on Tuesday announced the court-authorized disruption of a global network compromised by an advanced malware strain known as  Snake  wielded by Russia's Federal Security Service (FSB). Snake, dubbed the "most sophisticated cyber espionage tool," is the handiwork of a Russian state-sponsored group called  Turla  (aka Iron Hunter, Secret Blizzard, SUMMIT, Uroburos, Venomous Bear, and Waterbug), which the U.S. government attributes to a unit within Center 16 of the FSB. The threat actor has a  track record  of heavily focusing on entities in Europe, the Commonwealth of Independent States (CIS), and countries affiliated with NATO, with recent activity expanding its footprint to incorporate Middle Eastern nations deemed a threat to countries supported by Russia in the region. "For nearly 20 years, this unit [...] has used versions of the Snake malware to steal sensitive documents from hundreds of computer systems in at least 50 countries, ...

Microsoft has rolled out  Patch Tuesday updates  for May 2023 to address 38 security flaws, including two zero-day bugs that it said are being actively exploited in the wild. Trend Micro's Zero Day Initiative (ZDI)  said  the volume is the lowest since August 2021, although it pointed out that "this number is expected to rise in the coming months." Of the 38 vulnerabilities, six are rated Critical and 32 are rated Important in severity. Eight of the flaws have been tagged with "Exploitation More Likely" assessment by Microsoft. This is aside from  18 flaws  – including 11 bugs since the start of May – the Windows maker resolved in its Chromium-based Edge browser following the release of April Patch Tuesday updates. Topping the list is  CVE-2023-29336  (CVSS score: 7.8), a privilege escalation flaw in Win32k that has come under active exploitation. It's not immediately clear how widespread the attacks are. "An attacker who successfully explo...

U.S. authorities have announced the seizure of 13 internet domains that offered DDoS-for-hire services to other criminal actors. The takedown is part of an ongoing international initiative dubbed  Operation PowerOFF  that's aimed at dismantling criminal DDoS-for-hire infrastructures worldwide. The development comes almost five months after a "sweep" in December 2022  dismantled 48 similar services  for abetting paying users to launch distributed denial-of-service (DDoS) attacks against targets of interest. This includes school districts, universities, financial institutions, and government websites, according to the U.S. Department of Justice (DoJ). Ten of the 13 illicit domains seized are "reincarnations" of booter or stresser services that were previously shuttered towards the end of last year. "In recent years, booter services have continued to proliferate, as they offer a low barrier to entry for users looking to engage in cybercriminal activity,...

A gambling company in the Philippines was the target of a China-aligned threat actor as part of a campaign that has been ongoing since October 2021. Slovak cybersecurity firm ESET is tracking the series of attacks against Southeast Asian gambling companies under the name  Operation ChattyGoblin . "These attacks use a specific tactic: targeting the victim companies' support agents via chat applications – in particular, the Comm100 and LiveHelp100 apps," ESET  said  in a report shared with The Hacker News. The use of a trojanized Comm100 installer to deliver malware was  first documented  by CrowdStrike in October 2022. The company attributed the supply chain compromise to a threat actor likely with associations to China. The attack chains leverage the aforementioned chat apps to distribute a C# dropper that, in turn, deploys another C# executable, which ultimately serves as a conduit to drop a Cobalt Strike beacon on hacked workstations. Also highlighted in...

In the fast-paced cybersecurity landscape, product security takes center stage. DevSecOps swoops in, seamlessly merging security practices into DevOps, empowering teams to tackle challenges. Let's dive into DevSecOps and explore how collaboration can give your team the edge to fight cyber villains. Application security and product security Regrettably, application security teams often intervene late in the development process. They maintain the security level of exposed software, ensuring the integrity and confidentiality of consumed or produced data. They focus on securing data flows, isolating environments with firewalls, and implementing strong user authentication and access control. Product security teams aim to guarantee the intrinsic reliability of applications. They recommend tools and resources, making them available to developers and operations. In the DevSecOps approach, each team is responsible for the security of the applications they create. These teams apply secur...

The advanced persistent threat (APT) actor known as SideWinder has been accused of deploying a backdoor in attacks directed against Pakistan government organizations as part of a campaign that commenced in late November 2022. "In this campaign, the SideWinder advanced persistent threat (APT) group used a server-based polymorphism technique to deliver the next stage payload," the BlackBerry Research and Intelligence Team  said  in a technical report published Monday. Another campaign discovered by the Canadian cybersecurity company in early March 2023 shows that Turkey has also landed in the crosshairs of the threat actor's collection priorities. SideWinder  has been on the radar since at least 2012 and it's primarily known to target various Southeast Asian entities located across Pakistan, Afghanistan, Bhutan, China, Myanmar, Nepal, and Sri Lanka. Suspected to be an Indian state-sponsored group, SideWinder is also tracked under the monikers APT-C-17, APT-Q-39, Ha...

Iranian nation-state groups have now joined financially motivated actors in actively exploiting a critical flaw in PaperCut print management software, Microsoft disclosed over the weekend. The tech giant's threat intelligence team said it observed both Mango Sandstorm (Mercury) and Mint Sandstorm (Phosphorus) weaponizing CVE-2023-27350 in their operations to achieve initial access. "This activity shows Mint Sandstorm's continued ability to  rapidly incorporate [proof-of-concept] exploits  into their operations," Microsoft  said  in a series of tweets. On the other hand, CVE-2023-27350 exploitation activity associated with Mango Sandstorm is said to be on the lower end of the spectrum, with the state-sponsored group "using tools from prior intrusions to connect to their C2 infrastructure." It's worth noting that  Mango Sandstorm  is linked to Iran's Ministry of Intelligence and Security (MOIS) and  Mint Sandstorm  is associated with the Islam...

Cybersecurity researchers have shed light on a new ransomware strain called CACTUS that has been found to leverage known flaws in VPN appliances to obtain initial access to targeted networks. "Once inside the network, CACTUS actors attempt to enumerate local and network user accounts in addition to reachable endpoints before creating new user accounts and leveraging custom scripts to automate the deployment and detonation of the ransomware encryptor via scheduled tasks," Kroll said in a report shared with The Hacker News. The ransomware has been observed targeting large commercial entities since March 2023, with attacks employing double extortion tactics to steal sensitive data prior to encryption. No data leak site has been identified to date. Following a successful exploitation of vulnerable VPN devices, an SSH backdoor is set up to maintain persistent access and a series of PowerShell commands are executed to conduct network scanning and identify a list of machines fo...

The threat actors behind the ransomware attack on Taiwanese PC maker MSI last month have leaked the company's private code signing keys on their dark website. "Confirmed, Intel OEM private key leaked, causing an impact on the entire ecosystem," Alex Matrosov, founder and CEO of firmware security firm Binarly,  said  in a tweet over the weekend. "It appears that Intel Boot Guard may not be effective on certain devices based on the 11th Tiger Lake, 12th Adler Lake, and 13th Raptor Lake." Present in the leaked data are firmware image signing keys associated with 57 PCs and private signing keys for Intel Boot Guard used on 116 MSI products. The Boot Guard keys from MSI are believed to impact several device vendors, including Intel, Lenovo and Supermicro. Intel Boot Guard is a  hardware-based security technology  that's designed to protect computers against executing tampered UEFI firmware. The development comes a month after MSI  fell victim  to a double...

Digital storage giant Western Digital confirmed that an "unauthorized third party" gained access to its systems and stole personal information belonging to the company's online store customers. "This information included customer names, billing and shipping addresses, email addresses and telephone numbers," the San Jose-based company  said  in a disclosure last week. "In addition, the database contained, in encrypted format, hashed and salted passwords and partial credit card numbers. We will communicate directly with impacted customers." The development comes a little over a month after Western Digital  divulged  a "network security incident" on March 26, 2023, prompting the company to take its cloud services offline. A subsequent report from TechCrunch last month  revealed  that the threat actors behind the attack were allegedly in possession of "around 10 terabytes of data" and were negotiating with Western Digital for a ra...

The suspected Pakistan-aligned threat actor known as  SideCopy  has been observed leveraging themes related to the Indian military research organization as part of an ongoing phishing campaign. This involves using a ZIP archive lure pertaining to India's Defence Research and Development Organization ( DRDO ) to deliver a malicious payload capable of harvesting sensitive information, Fortinet FortiGuard Labs  said  in a new report. The cyber espionage group, with  activity  dating back to at least 2019, targets entities that align with Pakistan government interests. It's believed to share overlaps with another Pakistani hacking crew called  Transparent Tribe . SideCopy's use of DRDO-related decoys for malware distribution was previously flagged by  Cyble  and Chinese cybersecurity firm  QiAnXin  in March 2023, and again by  Team Cymru  last month. Interestingly, the same attack chains have been observed to load and ex...

Threat hunting is an essential component of your cybersecurity strategy. Whether you're getting started or in an advanced state, this article will help you ramp up your threat intelligence program. What is Threat Hunting? The cybersecurity industry is shifting from a reactive to a proactive approach. Instead of waiting for cybersecurity alerts and then addressing them, security organizations are now deploying red teams to actively seek out breaches, threats and risks, so they can be isolated. This is also known as "threat hunting."  Why is Threat Hunting Required? Threat hunting complements existing prevention and detection security controls. These controls are essential for mitigating threats. However, they are optimized for low false positive alerting. Hunt solutions, on the other hand, are optimized for low false negatives. This means that the anomalies and outliers that are considered false positives for detection solutions, are hunting solutions' leads, to b...

An ongoing phishing campaign with invoice-themed lures is being used to distribute the SmokeLoader malware in the form of a polyglot file, according to the Computer Emergency Response Team of Ukraine (CERT-UA). The emails, per the  agency , are sent using compromised accounts and come with a ZIP archive that, in reality, is a  polyglot file  containing a decoy document and a JavaScript file. The JavaScript code is then used to launch an executable that paves for the execution of the  SmokeLoader malware . SmokeLoader, first detected in 2011, is a  loader  whose main objective is to download or load a stealthier or more effective malware onto infected systems. CERT-UA attributed the activity to a threat actor it calls UAC-0006 and characterized it as a financially motivated operation carried out with the goal of stealing credentials and making unauthorized fund transfers. In a related advisory, Ukraine's cybersecurity authority also revealed details of...

An advanced persistent threat (APT) actor known as  Dragon Breath  has been observed adding new layers of complexity to its attacks by adopting a novel  DLL side-loading  mechanism. "The attack is based on a classic side-loading attack, consisting of a clean application, a malicious loader, and an encrypted payload, with various modifications made to these components over time," Sophos researcher Gabor Szappanos  said . "The latest campaigns add a twist in which a first-stage clean application 'side'-loads a second clean application and auto-executes it. The second clean application side-loads the malicious loader DLL. After that, the malicious loader DLL executes the final payload." Operation Dragon Breath, also tracked under the names APT-Q-27 and Golden Eye, was  first   documented  by QiAnXin in 2020, detailing a watering hole campaign designed to trick users into downloading a trojanized Windows installer for Telegram. A  subsequen...
