In the last few days, many Tor relay operators - mainly hosting relay nodes on providers like Hetzner - began receiving abuse notices.
All the abuses reported many failed SSH login attempts - part of a brute force attack - coming from their Tor relays.
Tor relays normally only transport traffic between a guard and an exit node of the Tor network, and per-se should not perform any SSH connections to internet-facing hosts, let alone performing SSH brute force attacks.
Attackers can downgrade Windows kernel components to bypass security features such as Driver Signature Enforcement and deploy rootkits on fully patched systems.

Emails, documents, and other untrusted content can plant malicious memories.
On August 25th 2024, Global Secure Layer mitigated the largest packet rate DDoS attack recorded against our platform
The total number of DDoS attacks during H1 2024 amounted to 830,000, an increase of 46% when compared to H1 2023, according to Gcore.
On July 15, 2024, Akamai prevented one of the largest distributed denial-of-service (DDoS) cyberattacks it has ever observed against a major financial services company in Israel.
The highly sophisticated, high-volume attack lasted almost 24 hours.
The attacker deployed larger-than-usual resources, indicating a serious risk for future attacks.
Other Israeli financial institutions reportedly suffered outages and downtimes on the same day, potentially due to the same type of attack and the same aggressor.
TuDoor is a new DNS attack, which could be exploited to carry out DNS cache poisoning, denial-of-service, and resource consuming.
DNS can be compared to a game of chess in that its rules are simple, yet the possibilities it presents are endless. While the fundamental rules of DNS are straightforward, DNS implementations can be extremely complex. In this study, we intend to explore the complexities and vulnerabilities in DNS response pre-processing by systematically analyzing DNS RFCs and DNS software implementations.
The Sykhiv residential area in Lviv was left without hot water and heating as a result of a hacker attack on Lvivteploenergo. This is reported on the company's website.
"The hacker attack disrupted the heat supply management system. Work is underway to restore heating and hot water supply in the Sykhiv residential area. The estimated time of restoration is 21:00," the statement said.
The National Health Laboratory Service is the primary diagnostic service for 80% of the population, and no timeline for its restoration has been determined

As “P4x,” Alejandro Caceres single-handedly disrupted the internet of an entire country. Then he tried to show the US military how it can—and should—adopt his methods.
Andres Freund published the existence of the xz attack on 2024-03-29 to the public oss-security@openwall mailing list. The day before, he alerted Debian security and the (private) distros@openwall list. In his mail, he says that he dug into this after “observing a few odd symptoms around liblzma (part of the xz package) on Debian sid installations over the last weeks (logins with ssh taking a lot of CPU, valgrind errors).”
At a high level, the attack is split in two pieces: a shell script and an object file. There is an injection of shell code during configure, which injects the shell code into make. The shell code during make adds the object file to the build. This post examines the shell script. (See also my timeline post.)
Automation is making attacks on open source code repositories harder to fight.
Researchers say it's the first known in-the-wild attack targeting AI workloads.
Several Apple customers recently reported being targeted in elaborate phishing attacks that involve what appears to be a bug in Apple's password reset feature. In this scenario, a target's Apple devices are forced to display dozens of system-level prompts that…
