Cloud company Rackspace has revealed it experienced a cybersecurity incident causing it to temporarily suspend its Hosted Exchange environment, which has now been restored. “On Friday, Dec 2, 2022, we became aware of an issue impacting our Hosted Exchange environment.

by Paul Ducklin One of the first low-level network tools that any computer user learns about is the venerable ping utility. Named after the eponymous sound effect from any and every old-school war movie scene involving submarines, the command is a metaphorical echo (see what we did there?) of the underwater version of RADAR known

Attackers have been increasingly encrypting malware in archives before releasing it in the wild.  According to HP Wolf Security’s latest Threat Insights Report Q3 2022, 44% of malware was delivered via archive files in the third quarter of 2022, an 11% increase from the previous quarter and substantially more than the 32% delivered through Office files. The

by Paul Ducklin It’s just under two weeks since Google rushed out a Chrome patch for the then-current version 107 to seal off a bug that was already being used in real-life attacks. The company said nothing more about that bug than to describe it as a “heap buffer overflow in GPU” [sic], and to

Threat actors have been spotted using criminal proxy networks to obfuscate their illegal activities by hiding behind hijacked IP addresses and using the same to create an appearance of legitimacy. The findings come from security researchers at DomainTools, who have said that while these networks were initially used as part of botnets, their lucrative nature

The annual number of memory safety vulnerabilities in Android dropped from 223 in 2019 to 85 in 2022 as Google gradually transitioned towards memory-safe languages.

by Paul Ducklin It’s just under a month since iOS 16.1.1 came out for Apple iPhone users, fixing a pair of bugs that were listed with the worrying words “a remote user may be able to cause unexpected app termination or arbitrary code execution”. Both macOS 13 Ventura and iPadOS got updated at the same

Colombian healthcare provider Keralty reported a ransomware attack on Sunday, which affected its systems as well as two of its subsidiaries: EPS Sanitas and Colsanitas.

by Paul Ducklin Back in August 2022, popular password manager company LastPass admitted to a data breach. The company, which is owned by sofware-as-a-service business GoTo, which used to be LogMeIn, published a very brief but nevertheless useful report about that incident about a month later: Briefly put, LastPass concluded that the attackers managed to

Nearly nine in 10 (87%) of US defense contractors are failing to meet basic cybersecurity regulation requirements, according to research commissioned by CyberSheath. The survey of 300 US-based Department of Defense (DoD) contractors found that just 13% of respondents have a Supplier Risk Performance System (SPRS) score of 70 or above. Under the Defense Federal

The legal declaration is, in the manner of such things, rather long and (to

The US Cybersecurity and Infrastructure Security Agency (CISA) added a critical flaw affecting Oracle Fusion Middleware systems to its Known Exploited Vulnerabilities (KEV) Catalog on Monday.

Successful attacks targeting this vulnerability

by Paul Ducklin Researchers at secure coding company Checkmarx have warned of porn-themed malware that’s been attracting and attacking sleazy internet users in droves. Unfortunately, the side-effects of this malware, dubbed Unfilter or Space Unfilter, apparently involve plundering data from the victim’s computer, including Discord passwords, thus indirectly exposing the victim’s contacts – such as

A phishing campaign discovered in July that saw threat actors impersonating the Ministry of Human Resources of the UAE government may be more significant in scale than previously believed. The findings come from security researchers at CloudSEK, who published a new advisory about the threat earlier today. The technical write-up says the company has discovered an

by Paul Ducklin Google has just patched Chrome’s eigth zero-day hole of the year so far. Zero-days are bugs for which there were zero days you could have updated proactively… …because cybercriminals not only found the bug first, but also figured out how to exploit it for nefarious purposes before a patch was prepared and

A series of exploits have been found in the wild targeting Windows Internet Key Exchange (IKE) Protocol Extensions.

Google attributed the discovery of the vulnerability to Clement Lecigne from its

Remote monitoring and management (RMM) platform ConnectWise has patched a cross-site scripting (XSS) vulnerability that could lead to remote code execution (RCE).

by Naked Security writer These days, most of us have telephones that display the number that’s calling before we answer. This “feature” actually goes right back to the 1960s, and it’s known in North American English as Caller ID, although it doesn’t actually identify the caller, just the caller’s number. Elsewhere in the English-speaking world,

The Bahamut APT group has been targeting Android users through a fake SecureVPN website since at least January 2022.

Simply put, these scammers use a variety of techniques, notably including prowling on dating sites, to meet people

A Vietnam-based hacking operation dubbed “Ducktail” is targeting individuals and companies operating on Facebook’s Ads and Business platform.

by Paul Ducklin Just under two months ago, some worrying bug news broke: a pair of zero-day vulnerabilities were announced in Microsoft Exchange. As we advised at the time, these vulnerabilities, officially designated CVE-2022-41040 and CVE-2022-41082: [were] two zero-days that [could] be chained together, with the first bug used remotely to open enough of a

Google has announced a legal victory against two Russian nationals connected with the Glupteba botnet. In a blog post last Friday, the tech giant said the court’s ruling against the botnet operators set a crucial legal precedent and sends a warning to cyber-criminals and their accomplices. “Last December, Google’s Threat Analysis Group (TAG) shared the
