Cyberattackers are targeting a post-authentication remote code-execution vulnerability in Symantec Secure Web Gateways as part of new Mirai and Hoaxcalls botnet attacks. Now, researchers at Palo Alto Networks' Unit 42 division have observed that same version of the botnet exploiting a second unpatched bug, this time in Symantec Secure Web Gateway version 5.0.2.8, which is a product that became end-of-life in 2015 and end-of-support-life in 2019.
That's especially true with phishing emails that attempt to hide the source of their deceptive landing pages and spoof or reference a well-known company or brand. A new phishing attack analyzed by Armorblox takes advantage of Symantec to trick users into falling for the scam.
Exploit acquisition firm Zerodium announced this week that it's no longer buying certain types of iOS exploits due to surplus, and the company expects prices to drop in the near future. Zerodium said on Twitter it would no longer acquire iOS local privilege escalation, Safari remote code execution, and sandbox escape exploits in the next 2-3 months "Due to a high number of submissions related to these vectors."
Business email compromise attacks continue to be a thorn in companies' sides, with the FBI in its IC3 annual cybercrime report saying that the attacks cost victims $1.7 billion in 2019. Making matters worse, BEC cybergangs are turning to new tactics and tricks to avoid detection and capitalize on existing victims.
On Wednesday, the software exploit broker said it won't pay anything for some iOS bugs due to an oversupply. Apple's iOS 13 has been particularly buggy, enough that SVP of software engineering Craig Federighi reportedly overhauled the company's internal software testing process to avoid a repeat when iOS 14 arrives later this year.
A Monero cryptocurrency-mining campaign has emerged that exploits a known vulnerability in public-facing web applications built on the ASP.NET open-source web framework. The campaign has been dubbed Blue Mockingbird by the analysts at Red Canary that discovered the activity.
In many cases, IT staff and other employees need to remotely connect to workstations and servers at the office, and for that they typically rely on the Microsoft Remote Desktop Protocol built into Windows. In a blog post published on Thursday, McAfee explains how cybercriminals are taking advantage of RDP access and what organizations can do to protect themselves.
A proof-of-concept exploit has been made public for a recently patched vulnerability in OpenSSL that can be exploited for denial-of-service attacks. OpenSSL versions 1.1.1d, 1.1.1e and 1.1.1f are affected by a high-severity vulnerability that has been described as a segmentation fault in the SSl check chain function.
Hackers targeted the publishing platform Ghost over the weekend, launching a cryptojacking attack against its servers that led to widespread outages. The attack stemmed from the exploit of critical vulnerabilities in SaltStack, used in Ghost's server management infrastructure.
Threat actors are using people's interest in the Department of Labor's Family and Medical Leave Act to spread what appears to be the TrickBot trojan in a new spam campaign that security researchers discovered recently. "Users infected with the TrickBot Trojan will see their device become part of a botnet that can allow attackers to gain complete control of the device," Via, along with IBM X-Force co-authors David Bryant and Limor Kessem, wrote in the post.
