Malicious actors have published more than 451 unique Python packages on the official Python Package Index (PyPI) repository in an attempt to infect developer systems with  clipper malware . Software supply chain security company Phylum, which  spotted the libraries , said the ongoing activity is a follow-up to a campaign that was initially disclosed in November 2022. The initial vector entails using  typosquatting  to mimic popular packages such as beautifulsoup, bitcoinlib, cryptofeed, matplotlib, pandas, pytorch, scikit-learn, scrapy, selenium, solana, and tensorflow, among others. "After installation, a malicious JavaScript file is dropped to the system and executed in the background of any web browsing session," Phylum  said  in a report published last year. "When a developer copies a cryptocurrency address, the address is replaced in the clipboard with the attacker's address." This is achieved by creating a Chromium web browser extension in the W...

One thing is clear. The " business value"  of data continues to grow, making it an organization's primary piece of intellectual property. From a cyber risk perspective, attacks on data are the most prominent threat to organizations.  Regulators, cyber insurance firms, and auditors are paying much closer attention to the integrity, resilience, and recoverability of organization data – as well as the IT infrastructure & systems that store the data. What Impact Does This Have On The Security Of Storage & Backup Systems? Just a few years ago, almost no CISO thought that storage & backups were important. That's no longer the case today.  Ransomware has pushed backup and recovery back onto the IT and corporate agenda. Cybercriminals, such as Conti, Hive and REvil, are  targeting storage and backup  systems, to prevent recovery. Some ransomwares – Locky and Crypto, for example – now bypass production systems altogether, and directly target backups. ...

Microsoft on Monday attributed a China-based cyber espionage actor to a set of attacks targeting diplomatic entities in South America. The tech giant's Security Intelligence team is tracking the cluster under the emerging moniker  DEV-0147 ,  describing  the activity as an "expansion of the group's data exfiltration operations that traditionally targeted government agencies and think tanks in Asia and Europe." The threat actor is said to use established hacking tools such as ShadowPad to infiltrate targets and maintain persistent access. ShadowPad, also called PoisonPlug, is a  successor  to the  PlugX remote access trojan  and has been widely put to use by Chinese adversarial collectives with links to the Ministry of State Security (MSS) and People's Liberation Army (PLA), per Secureworks. One of the other malicious tools utilized by DEV-0147 is a webpack loader called QuasarLoader , which allows for deploying additional payloads onto the compro...

Web infrastructure company Cloudflare on Monday disclosed that it thwarted a record-breaking distributed denial-of-service (DDoS) attack that peaked at over 71 million requests per second (RPS). "The majority of attacks peaked in the ballpark of 50-70 million requests per second (RPS) with the largest exceeding 71 million," the company  said , calling it a "hyper-volumetric" DDoS attack. It's also the largest HTTP DDoS attack reported to date, more than 35% higher than the previous 46 million RPS DDoS attack that  Google Cloud mitigated in June 2022 . Cloudflare said the attacks singled out websites secured by its platform and that they emanated from a botnet comprising more than 30,000 IP addresses that belonged to "numerous" cloud providers. Targeted websites included a popular gaming provider, cryptocurrency companies, hosting providers, and cloud computing platforms. HTTP attacks of this kind are designed to send a tsunami of HTTP requests t...

Apple on Monday rolled out security updates for  iOS, iPadOS ,  macOS , and  Safari  to address a zero-day flaw that it said has been actively exploited in the wild. Tracked as  CVE-2023-23529 , the issue relates to a type confusion bug in the WebKit browser engine that could be activated when processing maliciously crafted web content, culminating in arbitrary code execution. The iPhone maker said the bug was addressed with improved checks, adding it's "aware of a report that this issue may have been actively exploited." An anonymous researcher has been credited with reporting the flaw. It's not immediately clear as to how the vulnerability is being exploited in real-world attacks, but it's the second actively abused type confusion flaw in WebKit to be patched by Apple after  CVE-2022-42856  in as many months, which was closed in December 2022.  WebKit flaws are also notable for the fact that they impact every third-party web browser that's...

An unknown threat actor created malicious game modes for the Dota 2 multiplayer online battle arena (MOBA) video game that could have been exploited to establish backdoor access to players' systems. The modes exploited a  high-severity flaw  in the V8 JavaScript engine tracked as  CVE-2021-38003  (CVSS score: 8.8), which was  exploited as a zero-day  and addressed by Google in October 2021. "Since V8 was not sandboxed in Dota, the exploit on its own allowed for remote code execution against other Dota players," Avast researcher Jan Vojtěšek  said  in a report published last week. Following responsible disclosure to Valve, the game publisher  shipped fixes  on January 12, 2023, by upgrading the version of V8. Game modes are essentially  custom capabilities  that can either augment an existing title or offer completely new gameplay in a manner that deviates from the standard rules. While publishing a custom game mode to th...

The recently published Security Navigator report of Orange Cyberdefense shows there has been a  rapid increase of attacks on industrial control systems (ICS) in the past few years. Looking a bit closer, most of the attacks seem to have spilt over from traditional IT. That's to be expected, as production systems are commonly connected to ordinary corporate networks at this point.  Though the data does not indicate at this point that a lot of threat actors specifically target industrial systems – in fact, most evidence points to purely opportunistic behaviour – the tide could turn any time, once the added complexity of compromising OT environments promises to pay off. Criminals will take any chance they get to blackmail victims into extortion schemes, and halting production can cause immense damage. It is likely only a matter of time. So cybersecurity for operational technology (OT) is vitally important.  Deception is an effective option to improve threat detection and r...

The advanced persistent threat (APT) actor known as  Tonto Team  carried out an unsuccessful attack on cybersecurity company Group-IB in June 2022. The Singapore-headquartered firm  said  that it detected and blocked malicious phishing emails originating from the group targeting its employees. It's also the second attack aimed at Group-IB, the first of which took place in March 2021. Tonto Team, also called Bronze Huntley,  Cactus Pete , Earth Akhlut, Karma Panda, and UAC-0018, is a suspected Chinese hacking group that has been linked to attacks targeting a wide range of organizations in Asia and Eastern Europe. The actor is known to be active since at least 2009 and is said to  share ties  to the Third Department ( 3PLA ) of the People's Liberation Army's Shenyang TRB ( Unit 65016 ). Attack chains involve spear-phishing lures containing malicious attachments created using the Royal Road Rich Text Format (RTF) exploitation toolkit to drop backdoo...

A previously unknown threat actor has been targeting companies in the U.S. and Germany with bespoke malware designed to steal confidential information. Enterprise security company Proofpoint, which is tracking the activity cluster under the name  Screentime , said the group, dubbed  TA866 , is likely financially motivated. "TA866 is an organized actor able to perform well thought-out attacks at scale based on their availability of custom tools; ability and connections to purchase tools and services from other vendors; and increasing activity volumes," the company  assessed . Campaigns mounted by the adversary are said to have commenced around October 3, 2022, with the attacks launched via emails containing a booby-trapped attachment or URL that leads to malware. The attachments range from macro-laced Microsoft Publisher files to PDFs with URLs pointing to JavaScript files. The intrusions have also leveraged conversation hijacking to entice recipients into clicking on...

After the U.S. Cybersecurity and Infrastructure Security Agency (CISA) released a decryptor for affected victims to recover from  ESXiArgs ransomware attacks , the threat actors have bounced back with an updated version that encrypts more data. The emergence of the new variant was reported by a system administrator on an online forum, where another participant stated that files larger than 128MB will have 50% of their data encrypted, making the recovery process more challenging. Another notable change is the removal of the Bitcoin address from the ransom note, with the attackers now urging victims to contact them on Tox to obtain the wallet information. The threat actors "realized that researchers were tracking their payments, and they may have even known before they released the ransomware that the encryption process in the original variant was relatively easy to circumvent," Censys  said  in a write-up. "In other words: they are watching." Statistics shared...

Suspected Russian threat actors have been targeting Eastern European users in the crypto industry with fake job opportunities as bait to install information-stealing malware on compromised hosts. The attackers "use several highly obfuscated and under-development custom loaders in order to infect those involved in the cryptocurrency industry with Enigma stealer," Trend Micro researchers Aliakbar Zahravi and Peter Girnus  said  in a report this week. Enigma is said to be an altered version of Stealerium, an open source C#-based malware that acts as a stealer, clipper, and keylogger. The intricate infection journey starts with a rogue RAR archive file that's distributed via phishing or social media platforms. It contains two documents, one of which is a .TXT file that includes a set of sample interview questions related to cryptocurrency. The second file is a Microsoft Word document that, while serving as a decoy, is tasked with launching the first-stage Enigma loader, ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday  added  three flaws to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active abuse in the wild. Included among the three is  CVE-2022-24990 , a bug affecting TerraMaster network-attached storage (TNAS) devices that could lead to unauthenticated remote code execution with the highest privileges. Details about the flaw were  disclosed  by Ethiopian cyber security research firm Octagon Networks in March 2022. The vulnerability, according to a  joint advisory  released by U.S. and South Korean government authorities, is said to have been weaponized by North Korean nation-state hackers to strike healthcare and critical infrastructure entities with ransomware. The second shortcoming to be added to KEV catalog is  CVE-2015-2291 , an unspecified flaw in the Intel ethernet diagnostics driver for Windows (IQVW32.sys and IQVW64.sys) that could throw an a...

Four different rogue packages in the Python Package Index ( PyPI ) have been found to carry out a number of malicious actions, including dropping malware, deleting the netstat utility, and manipulating the SSH authorized_keys file. The packages in question are  aptx ,  bingchilling2 ,  httops , and  tkint3rs , all of which were collectively downloaded about 450 times before they were taken down. While aptx is an attempt to impersonate Qualcomm's  highly popular audio codec  of the same name, httops and tkint3rs are typosquats of https and tkinter, respectively. "Most of these packages had well thought out names, to purposely confuse people," security researcher and journalist Ax Sharma  said . An analysis of the malicious code injected in the setup script reveals the presence of an obfuscated  Meterpreter payload  that's disguised as " pip ," a legitimate package installer for Python, and which can be leveraged to gain shell access to the...
