Twilio, which earlier this month became a  sophisticated phishing attack , disclosed last week that the threat actors also managed to gain access to the accounts of 93 individual users of its Authy two-factor authentication (2FA) service. The communication tools company  said  the unauthorized access made it possible for the adversary to register additional devices to those accounts. It has since identified and removed the illegitimately added devices from the impacted accounts. Authy, acquired by Twilio in February 2015, allows  safeguarding online accounts  with a second security layer to prevent account takeover attacks. It's estimated to have nearly 75 million users. Twilio further noted its investigation as of August 24, 2022, turned up 163 affected customers, up from 125 it reported on August 10, whose accounts it said were hacked for a limited period of time. Besides Twilio, the sprawling campaign, dubbed  0ktapus  by Group-IB, is believed...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added 10 new actively exploited vulnerabilities to its  Known Exploited Vulnerabilities (KEV) Catalog , including a high-severity security flaw affecting industrial automation software from Delta Electronics. The issue, tracked as  CVE-2021-38406  (CVSS score: 7.8), impacts DOPSoft 2 versions 2.00.07 and prior. A successful exploitation of the flaw may lead to arbitrary code execution. "Delta Electronics DOPSoft 2 lacks proper validation of user-supplied data when parsing specific project files (improper input validation) resulting in an out-of-bounds write that allows for code execution," CISA said in an alert. It's worth noting that CVE-2021-38406 was originally disclosed as part of an industrial control systems (ICS) advisory  published  in September 2021. However, there are no patches that address the vulnerability, with CISA noting that the "impacted product is end-of-life and ...

Iranian state-sponsored actors are leaving no stone unturned to exploit unpatched systems running Log4j to target Israeli entities, indicating the vulnerability's  long tail  for remediation. Microsoft attributed the latest set of activities to the  umbrella threat group  tracked as  MuddyWater  (aka Cobalt Ulster, Mercury, Seedworm, or Static Kitten), which is  linked  to the Iranian intelligence apparatus, the Ministry of Intelligence and Security (MOIS). The attacks are notable for using SysAid Server instances unsecured against the  Log4Shell flaw  as a vector for initial access,  marking  a  departure  from the actors' pattern of leveraging VMware applications for breaching target environments. "After gaining access, Mercury establishes persistence, dumps credentials, and moves laterally within the targeted organization using both custom and well-known hacking tools, as well as built-in operating system tool...

While phishing and ransomware dominate headlines, another critical risk quietly persists across most enterprises: exposed Git repositories leaking sensitive data. A risk that silently creates shadow access into core systems Git is the backbone of modern software development, hosting millions of repositories and serving thousands of organizations worldwide. Yet, amid the daily hustle of shipping code, developers may inadvertently leave behind API keys, tokens, or passwords in configuration files and code files, effectively handing attackers the keys to the kingdom. This isn't just about poor hygiene; it's a systemic and growing supply chain risk. As cyber threats become more sophisticated, so do compliance requirements. Security frameworks like NIS2, SOC2, and ISO 27001 now demand proof that software delivery pipelines are hardened and third-party risk is controlled. The message is clear: securing your Git repositories is no longer optional, it's essential. Below, we look at the ris...

Atlassian has rolled out fixes for a  critical security flaw  in Bitbucket Server and Data Center that could lead to the execution of malicious code on vulnerable installations. Tracked as  CVE-2022-36804  (CVSS score: 9.9), the issue has been characterized as a command injection vulnerability in multiple endpoints that could be exploited via specially crafted HTTP requests. "An attacker with access to a public Bitbucket repository or with read permissions to a private one can execute arbitrary code by sending a malicious HTTP request," Atlassian  said  in an advisory. The shortcoming, discovered and reported by security researcher  @TheGrandPew  impacts all versions of Bitbucket Server and Datacenter released after 6.10.17, inclusive of 7.0.0 and newer - Bitbucket Server and Datacenter 7.6 Bitbucket Server and Datacenter 7.17 Bitbucket Server and Datacenter 7.21 Bitbucket Server and Datacenter 8.0 Bitbucket Server and Datacenter 8.1 B...

Password management service LastPass confirmed a security incident that resulted in the theft of certain source code and technical information. The security breach is said to have occurred two weeks ago, targeting its development environment. No customer data or encrypted passwords were accessed, although the company provided no further details regarding the hack and what source code was stolen. "An unauthorized party gained access to portions of the LastPass development environment through a single compromised developer account and took portions of source code and some proprietary LastPass technical information," LastPass CEO Karim Toubba  said . Amidst ongoing investigation into the incident, the company said it has engaged the services of a leading cybersecurity and forensics firm and that it has implemented additional countermeasures. LastPass, however, didn't elaborate on the exact mitigation techniques that it used to strengthen its environment. It also reiterated that...

Nation-state threat actors are  increasingly adopting  and integrating the Sliver command-and-control (C2) framework in their intrusion campaigns as a replacement for Cobalt Strike. "Given Cobalt Strike's popularity as an attack tool, defenses against it have also improved over time," Microsoft security experts  said . "Sliver thus presents an attractive alternative for actors looking for a lesser-known toolset with a low barrier for entry." Sliver, first made public in late 2019 by cybersecurity company BishopFox, is a Go-based  open source C2 platform  that supports user-developed extensions, custom implant generation, and other commandeering options. "A C2 framework usually includes a server that accepts connections from implants on a compromised system, and a client application that allows the C2 operators to interact with the implants and launch malicious commands," Microsoft said. Besides facilitating long-term access to infected hosts, the cross-pl...

The threat actor behind the attacks on  Twilio  and  Cloudflare  earlier this month has been linked to a broader phishing campaign aimed at 136 organizations that resulted in a cumulative compromise of 9,931 accounts. The activity has been condemned  0ktapus  by Group-IB because the initial goal of the attacks was to "obtain Okta identity credentials and two-factor authentication (2FA) codes from users of the targeted organizations." Calling the attacks well designed and executed, the Singapore-headquartered company said the adversary singled out employees of companies that are customers of identity services provider Okta. The modus operandi involved sending targets text messages containing links to phishing sites that impersonated the Okta authentication page of the respective targeted entities. "This case is of interest because despite using low-skill methods it was able to compromise a large number of well-known organizations," Group-IB  said ...
