Big bad decryption bug in OpenSSL but no cause for alarm

nakedsecurity.sophos.com/2021/08/27/big-bad-decryption-bug-in-openssl-but-no-cause-for-alarm/ The well-known and widely-used encryption library OpenSSL released a security patch earlier this week. OpenSSL, as its name suggests, is mainly used by network software that uses the TLS protocol (transport layer security), formerly known as SSL (secure sockets layer), to protect data in transit. Although TLS has now replaced SSL, removing a huge number of cryptographic flaws along the way, many of the popular open source programming libraries that support it, such as OpenSSL, LibreSSL and BoringSSL, have kept old-school product names for the sake of familiarity

Widespread credential phishing campaign abuses open redirector links

www.microsoft.com/security/blog/2021/08/26/widespread-credential-phishing-campaign-abuses-open-redirector-links/ Microsoft has been actively tracking a widespread credential phishing campaign using open redirector links. Attackers combine these links with social engineering baits that impersonate well-known productivity tools and services to lure users into clicking. Doing so leads to a series of redirectionsincluding a CAPTCHA verification page that adds a sense of legitimacy and attempts to evade some automated analysis systemsbefore taking the user to a fake sign-in page. This ultimately leads to credential compromise, which opens the user and their organization to other attacks.

Fake DMCA complaints, DDoS threats lead to BazaLoader malware

www.bleepingcomputer.com/news/security/fake-dmca-complaints-ddos-threats-lead-to-bazaloader-malware/ Cybercriminals behind the BazaLoader malware came up with a new lure to trick website owners into opening malicious files: fake notifications about the site being engaged in distributed denial-of-service (DDoS) attacks. The messages contain a legal threat and a file stored in a Google Drive folder that allegedly provides evidence of the source of the attack. The DDoS theme is a variation of another lure, a Digital Millennium Copyright Act (DMCA) infringement complaint linking to a file that supposedly contains evidence about stealing images.

Laskutusjärjestelmä oli jumissa, eikä bensaa kannattanut toimittaa ilmaiseksi Texasista New Yorkiin. Kannattaako joskus siis maksaa kiristäjille? Kysymys saa Viria Securityn kyberturvallisuudesta vastaavan johtajan Benjamin Särkän huokaamaan.
