Cisco is warning about a global surge in brute-force attacks targeting various devices, including Virtual Private Network (VPN) services, web application authentication interfaces, and SSH services, since at least March 18, 2024. "These attacks all appear to be originating from TOR exit nodes and a range of other anonymizing tunnels and proxies," Cisco Talos  said . Successful attacks could pave the way for unauthorized network access, account lockouts, or denial-of-service conditions, the cybersecurity company added. The attacks, said to be broad and opportunistic, have been observed targeting the below devices - Cisco Secure Firewall VPN  Checkpoint VPN Fortinet VPN SonicWall VPN RD Web Services  Mikrotik  Draytek  Ubiquiti  Cisco Talos described the brute-forcing attempts as using both generic and valid usernames for specific organizations, with the attacks indiscriminately targeting a wide range of sectors across geographies. The source IP addresses for t

A threat group of suspected Romanian origin called  RUBYCARP  has been observed maintaining a long-running botnet for carrying out crypto mining, distributed denial-of-service (DDoS), and phishing attacks. The group, believed to be active for at least 10 years, employs the botnet for financial gain, Sysdig said in a report shared with The Hacker News. "Its primary method of operation leverages a botnet deployed using a variety of public exploits and brute-force attacks," the cloud security firm said . "This group communicates via public and private IRC networks." Evidence  gathered  so far suggests that RUBYCARP may have crossover with another threat cluster tracked by Albanian cybersecurity firm Alphatechs under the moniker Outlaw , which has a history of conducting crypto mining and brute-force attacks and has since pivoted to phishing and spear-phishing campaigns to cast a wide net. "These phishing emails often lure victims into revealing sensitive i

Imagine a world where the software that powers your favorite apps, secures your online transactions, and keeps your digital life could be outsmarted and taken over by a cleverly disguised piece of code. This isn't a plot from the latest cyber-thriller; it's actually been a reality for years now. How this will change – in a positive or negative direction – as artificial intelligence (AI) takes on a larger role in software development is one of the big uncertainties related to this brave new world. In an era where AI promises to revolutionize how we live and work, the conversation about its security implications cannot be sidelined. As we increasingly rely on AI for tasks ranging from mundane to mission-critical, the question is no longer just, "Can AI  boost cybersecurity ?" (sure!), but also "Can AI  be hacked? " (yes!), "Can one use AI  to hack? " (of course!), and "Will AI  produce secure software ?" (well…). This thought leadership article is about the latter. Cydrill  (a

Threat actors are actively scanning and exploiting a pair of security flaws that are said to affect as many as 92,000 internet-exposed D-Link network-attached storage (NAS) devices. Tracked as  CVE-2024-3272  (CVSS score: 9.8) and  CVE-2024-3273  (CVSS score: 7.3), the vulnerabilities impact  legacy D-Link products  that have reached end-of-life (EoL) status. D-Link, in an  advisory , said it does not plan to ship a patch and instead urges customers to replace them. "The vulnerability lies within the nas_sharing.cgi uri, which is vulnerable due to two main issues: a backdoor facilitated by hard-coded credentials, and a command injection vulnerability via the system parameter," security researcher who goes by the name netsecfish  said  in late March 2024. Successful exploitation of the flaws could lead to arbitrary command execution on the affected D-Link NAS devices, granting threat actors the ability to access sensitive information, alter system configurations, or even

Threat hunters have discovered a new malware called  Latrodectus  that has been distributed as part of email phishing campaigns since at least late November 2023. "Latrodectus is an up-and-coming downloader with various sandbox evasion functionality," researchers from Proofpoint and Team Cymru  said  in a joint analysis published last week, adding it's designed to retrieve payloads and execute arbitrary commands. There is evidence to suggest that the downloader is likely written by the same threat actors behind the  IcedID malware , with the downloader put to use by initial access brokers (IABs) to facilitate the deployment of other malware. Latrodectus has been primarily linked to two different IABs tracked by Proofpoint under the names  TA577  (aka Water Curupira) and TA578, the former of which has also been linked to the distribution of QakBot and PikaBot. As of mid-January 2024, it's been employed almost exclusively by TA578 in email threat campaigns, in some

Several malicious Android apps that turn mobile devices running the operating system into residential proxies (RESIPs) for other threat actors have been observed on the Google Play Store. The findings come from HUMAN's Satori Threat Intelligence team, which said the cluster of VPN apps came fitted with a Golang library that transformed the user's device into a proxy node without their knowledge. The operation has been codenamed  PROXYLIB  by the company. The 29 apps in question have since been removed by Google. Residential proxies are a network of proxy servers sourced from real IP addresses provided by internet service providers (ISPs), helping users hide their actual IP addresses by routing their internet traffic through an intermediary server. The anonymity benefits aside, they are ripe for abuse by threat actors to not only obfuscate their origins, but also to conduct a wide range of attacks. "When a threat actor uses a residential proxy, the traffic from these
