Sality botnet infrastructure dismantled in joint global takedown

11h ago · bleeping-computer

The Sality botnet, active for over two decades and responsible for infecting more than 15,000 devices, has been disrupted in a joint global takedown operation led by international law enforcement and private sector partners including Europol, FBI, and CrowdStrike. The botnet, attributed to the threat actor group SALTY SPIDER believed to be operating from Russia's Republic of Bashkortostan, used a peer-to-peer (P2P) architecture to distribute malware payloads, primarily EggJagger in recent years. EggJagger is a clipjacking tool that monitors and replaces cryptocurrency wallet addresses in the clipboard with attacker-controlled ones. The disruption was achieved by sinkholing the botnet’s super peer infrastructure, effectively severing communication between infected machines and preventing further propagation of malicious payloads.

Hackers abuse Faronics Deploy admin tool to install ScreenConnect

22h ago · bleeping-computer

Hackers are exploiting the legitimate Faronics Deploy endpoint management tool to gain remote administrative access to victim systems by tricking users into installing a maliciously repurposed, signed installer disguised as an Adobe-related executable. The installer enrolls the victim's machine into an attacker-controlled Faronics deployment, enabling the execution of PowerShell scripts that deploy additional payloads, including ConnectWise ScreenConnect, a remote access tool used for persistent and interactive control. The attack uses phishing emails with business-themed lures, such as fake invoices, and includes anti-analysis techniques to evade detection in sandboxed environments. Activity declined after Faronics implemented anti-abuse measures in response to disclosure by Huntress.

Chinese Fire Ant hackers turn Cisco routers into spying platforms

2d ago · bleeping-computer

The Chinese state-sponsored threat actor Fire Ant has shifted tactics to compromise Cisco IOS XR routers, TACACS servers, and Linux management systems, turning routers into surveillance platforms via concealed GRE tunnels. The group deployed a custom backdoor named 'BridgeAgent', disguised as a Zabbix agent, enabling reverse shells and execution of additional payloads. Fire Ant uses stealthy persistence mechanisms, suppresses syslog messages, and exfiltrates network traffic PCAPs to FTP servers, aiming to map and access high-value networks through a 'target behind the target' strategy. The group's activity overlaps with UNC3886 but shows distinct implementation differences.

Cronos blockchain restarts after $74 million Tectonic exploit

1d ago · bleeping-computer

The Cronos blockchain was exploited via a price-manipulation attack on the Tectonic DeFi lending platform, resulting in the attacker borrowing $74 million worth of assets by artificially inflating the value of the TONIC token by 100x within 20 minutes. The attacker successfully withdrew approximately $6 million in Ethereum, while the remainder of the funds were frozen due to the blockchain's emergency response. Cronos halted operations, rolled back the chain state to before the exploit occurred, and has since resumed normal operations. A post-mortem analysis is expected to follow.
